It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell command './configure && make && make install' +should configure, build, and install this package. The following +more-detailed instructions are generic; see the 'README' file for +instructions specific to this package. Some packages provide this +'INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The 'configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a 'Makefile' in each directory of the package. +It may also create one or more '.h' files containing system-dependent +definitions. Finally, it creates a shell script 'config.status' that +you can run in the future to recreate the current configuration, and a +file 'config.log' containing compiler output (useful mainly for +debugging 'configure'). + + It can also use an optional file (typically called 'config.cache' and +enabled with '--cache-file=config.cache' or simply '-C') that saves the +results of its tests to speed up reconfiguring. Caching is disabled by +default to prevent problems with accidental use of stale cache files. + + If you need to do unusual things to compile the package, please try +to figure out how 'configure' could check whether to do them, and mail +diffs or instructions to the address given in the 'README' so they can +be considered for the next release. If you are using the cache, and at +some point 'config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file 'configure.ac' (or 'configure.in') is used to create +'configure' by a program called 'autoconf'. You need 'configure.ac' if +you want to change it or regenerate 'configure' using a newer version of +'autoconf'. + + The simplest way to compile this package is: + + 1. 'cd' to the directory containing the package's source code and type + './configure' to configure the package for your system. + + Running 'configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type 'make' to compile the package. + + 3. Optionally, type 'make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type 'make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the 'make install' phase executed with root + privileges. + + 5. Optionally, type 'make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior 'make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing 'make clean'. To also remove the + files that 'configure' created (so you can compile the package for + a different kind of computer), type 'make distclean'. There is + also a 'make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type 'make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide 'make + distcheck', which can by used by developers to test that all other + targets like 'make install' and 'make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the 'configure' script does not know about. Run './configure --help' +for details on some of the pertinent environment variables. + + You can give 'configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here is +an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU 'make'. 'cd' to the +directory where you want the object files and executables to go and run +the 'configure' script. 'configure' automatically checks for the source +code in the directory that 'configure' is in and in '..'. This is known +as a "VPATH" build. + + With a non-GNU 'make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use 'make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple '-arch' options to the +compiler but only a single '-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the 'lipo' tool if you have problems. + +Installation Names +================== + + By default, 'make install' installs the package's commands under +'/usr/local/bin', include files under '/usr/local/include', etc. You +can specify an installation prefix other than '/usr/local' by giving +'configure' the option '--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option '--exec-prefix=PREFIX' to 'configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like '--bindir=DIR' to specify different values for particular +kinds of files. Run 'configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the default +for these options is expressed in terms of '${prefix}', so that +specifying just '--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to 'configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +'make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, 'make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +'${prefix}'. Any directories that were specified during 'configure', +but not in terms of '${prefix}', must each be overridden at install time +for the entire installation to be relocated. The approach of makefile +variable overrides for each directory variable is required by the GNU +Coding Standards, and ideally causes no recompilation. However, some +platforms have known limitations with the semantics of shared libraries +that end up requiring recompilation when using this method, particularly +noticeable in packages that use GNU Libtool. + + The second method involves providing the 'DESTDIR' variable. For +example, 'make install DESTDIR=/alternate/directory' will prepend +'/alternate/directory' before all installation names. The approach of +'DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of '${prefix}' +at 'configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving 'configure' the +option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. + + Some packages pay attention to '--enable-FEATURE' options to +'configure', where FEATURE indicates an optional part of the package. +They may also pay attention to '--with-PACKAGE' options, where PACKAGE +is something like 'gnu-as' or 'x' (for the X Window System). The +'README' should mention any '--enable-' and '--with-' options that the +package recognizes. + + For packages that use the X Window System, 'configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the 'configure' options '--x-includes=DIR' and +'--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of 'make' will be. For these packages, running './configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with 'make V=1'; while running './configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with 'make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC +is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX 'make' updates targets which have the same time stamps as their +prerequisites, which makes it generally unusable when shipped generated +files such as 'configure' are involved. Use GNU 'make' instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its '' header file. The option '-nodtk' can be used as a +workaround. If GNU CC is not installed, it is therefore recommended to +try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put '/usr/ucb' early in your 'PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in '/usr/bin'. So, if you need '/usr/ucb' +in your 'PATH', put it _after_ '/usr/bin'. + + On Haiku, software installed for all users goes in '/boot/common', +not '/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features 'configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, 'configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +'--build=TYPE' option. TYPE can either be a short name for the system +type, such as 'sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file 'config.sub' for the possible values of each field. If +'config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option '--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with '--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for 'configure' scripts to share, +you can create a site shell script called 'config.site' that gives +default values for variables like 'CC', 'cache_file', and 'prefix'. +'configure' looks for 'PREFIX/share/config.site' if it exists, then +'PREFIX/etc/config.site' if it exists. Or, you can set the +'CONFIG_SITE' environment variable to the location of the site script. +A warning: not all 'configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to 'configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the 'configure' command line, using 'VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified 'gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an +Autoconf limitation. Until the limitation is lifted, you can use this +workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +'configure' Invocation +====================== + + 'configure' recognizes the following options to control how it +operates. + +'--help' +'-h' + Print a summary of all of the options to 'configure', and exit. + +'--help=short' +'--help=recursive' + Print a summary of the options unique to this package's + 'configure', and exit. The 'short' variant lists options used only + in the top level, while the 'recursive' variant lists options also + present in any nested packages. + +'--version' +'-V' + Print the version of Autoconf used to generate the 'configure' + script, and exit. + +'--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally 'config.cache'. FILE defaults to '/dev/null' to + disable caching. + +'--config-cache' +'-C' + Alias for '--cache-file=config.cache'. + +'--quiet' +'--silent' +'-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to '/dev/null' (any error + messages will still be shown). + +'--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + 'configure' can determine that directory automatically. + +'--prefix=DIR' + Use DIR as the installation prefix. *note Installation Names:: for + more details, including other options available for fine-tuning the + installation locations. + +'--no-create' +'-n' + Run the configure checks, but stop before creating any output + files. + +'configure' also accepts some other, not widely useful, options.

GNU libmicrohttpd only implements the HTTP 1.1 +protocol. The main application must still provide the application +logic to generate the content. + +GNU libmicrohttpd is dual-licensed under the GNU Lesser General Public +License (LGPLv3+) and the eCos License. See COPYING for details. + + +Installation +============ + +See INSTALL for generic installation instructions. + +If you are using Git, run "autoreconf -fi" to create configure. + +In order to run the testcases, you need a recent version of libcurl. +libcurl is not required if you just want to install the library. + +Especially for development, do use the MHD_USE_ERROR_LOG option to get +error messages. + + +Configure options +================= + + +If you are concerned about space, you should set "CFLAGS" to "-Os +-fomit-frame-pointer" to have gcc generate tight code. + +You can use the following options to disable certain MHD features: + +--disable-https: no HTTPS / TLS / SSL support (significant reduction) +--disable-messages: no error messages (they take space!) +--disable-postprocessor: no MHD_PostProcessor API +--disable-dauth: no digest authentication API +--disable-epoll: no support for epoll, even on Linux + +The resulting binary should be about 30-40k depending on the platform. + + +Portability +=========== + +The latest version of libmicrohttpd will try to avoid SIGPIPE on its +sockets. This should work on OS X, Linux and recent BSD systems (at +least). On other systems that may trigger a SIGPIPE on send/recv, the +main application should install a signal handler to handle SIGPIPE. + +libmicrohttpd should work well on GNU/Linux, W32, FreeBSD, Darwin, +NetBSD, OpenBSD, Solaris/OpenIndiana, and z/OS. +Note that HTTPS is not supported on z/OS (yet). We also have reports +of users using it on vxWorks. + + +Development Status +================== + +This is a beta release for libmicrohttpd.

Keep in mind that a server might have to satisfy hundreds +of concurrent connections and we have to make sure that the correct data is sent to the destined +client. Therefore, this variable is a means to refer to a particular connection if we ask the +daemon to sent the reply. + +Talking about the reply, it is defined as a string right after the function header +@verbatim +int answer_to_connection (void *cls, struct MHD_Connection *connection, + const char *url, + const char *method, const char *version, + const char *upload_data, + size_t *upload_data_size, void **con_cls) +{ + const char *page = "Hello, browser!"; + +@end verbatim + +@noindent +HTTP is a rather strict protocol and the client would certainly consider it "inappropriate" if we +just sent the answer string "as is". Instead, it has to be wrapped with additional information stored in so-called headers and footers. Most of the work in this area is done by the library for us---we +just have to ask. Our reply string packed in the necessary layers will be called a "response". +To obtain such a response we hand our data (the reply--string) and its size over to the +@code{MHD_create_response_from_buffer} function. The last two parameters basically tell @emph{MHD} +that we do not want it to dispose the message data for us when it has been sent and there also needs +no internal copy to be done because the @emph{constant} string won't change anyway. + +@verbatim + struct MHD_Response *response; + int ret; + + response = MHD_create_response_from_buffer (strlen (page), + (void*) page, MHD_RESPMEM_PERSISTENT); + +@end verbatim + +@noindent +Now that the the response has been laced up, it is ready for delivery and can be queued for sending. +This is done by passing it to another @emph{GNU libmicrohttpd} function. As all our work was done in +the scope of one function, the recipient is without doubt the one associated with the +local variable @code{connection} and consequently this variable is given to the queue function. +Every HTTP response is accompanied by a status code, here "OK", so that the client knows +this response is the intended result of his request and not due to some error or malfunction. + +Finally, the packet is destroyed and the return value from the queue returned, +already being set at this point to either MHD_YES or MHD_NO in case of success or failure. + +@verbatim + ret = MHD_queue_response (connection, MHD_HTTP_OK, response); + MHD_destroy_response (response); + + return ret; +} + +@end verbatim + +@noindent +With the primary task of our server implemented, we can start the actual server daemon which will listen +on @code{PORT} for connections. This is done in the main function. +@verbatim +int main () +{ + struct MHD_Daemon *daemon; + + daemon = MHD_start_daemon (MHD_USE_INTERNAL_POLLING_THREAD, PORT, NULL, NULL, + &answer_to_connection, NULL, MHD_OPTION_END); + if (NULL == daemon) return 1; + +@end verbatim + +@noindent +The first parameter is one of three possible modes of operation. Here we want the daemon to run in +a separate thread and to manage all incoming connections in the same thread.

In this +example, where the reply is already known and therefore the request is served quickly, this poses no problem. + +We will allow all clients to connect regardless of their name or location, therefore we do not check +them on connection and set the third and fourth parameter to NULL. + +Parameter five is the address of the function we want to be called whenever a new connection has been +established. Our @code{answer_to_connection} knows best what the client wants and needs no additional +information (which could be passed via the next parameter) so the next (sixth) parameter is NULL. Likewise, +we do not need to pass extra options to the daemon so we just write the MHD_OPTION_END as the last parameter. + +As the server daemon runs in the background in its own thread, the execution flow in our main +function will contine right after the call. Because of this, we must delay the execution flow in the +main thread or else the program will terminate prematurely.

If everything works as expected, the browser will present the message of the +static HTML page it got from our minimal server. + +@heading Remarks +To keep this first example as small as possible, some drastic shortcuts were taken and are to be +discussed now. + +Firstly, there is no distinction made between the kinds of requests a client could send. We implied +that the client sends a GET request, that means, that he actually asked for some data. Even when +it is not intended to accept POST requests, a good server should at least recognize that this +request does not constitute a legal request and answer with an error code. This can be easily +implemented by checking if the parameter @code{method} equals the string "GET" and returning a +@code{MHD_NO} if not so. + +Secondly, the above practice of queuing a response upon the first call of the callback function +brings with it some limitations. This is because the content of the message body will not be +received if a response is queued in the first iteration. Furthermore, the connection will be closed +right after the response has been transferred then. This is typically not what you want as it +disables HTTP pipelining. The correct approach is to simply not queue a message on the first +callback unless there is an error. The @code{void**} argument to the callback provides a location +for storing information about the history of the connection; for the first call, the pointer +will point to NULL. A simplistic way to differenciate the first call from others is to check +if the pointer is NULL and set it to a non-NULL value during the first call. + +Both of these issues you will find addressed in the official @code{minimal_example.c} residing in +the @code{src/examples} directory of the @emph{MHD} package. The source code of this +program should look very familiar to you by now and easy to understand. + +For our example, we create the response from a static (persistent) buffer in memory and thus pass @code{MHD_RESPMEM_PERSISTENT} to the response construction +function. In the usual case, responses are not transmitted immediately +after being queued. For example, there might be other data on the system that needs to be sent with +a higher priority. Nevertheless, the queue function will return successfully---raising the problem +that the data we have pointed to may be invalid by the time it is about being sent. This is not an +issue here because we can expect the @code{page} string, which is a constant @emph{string literal} +here, to be static. That means it will be present and unchanged for as long as the program runs. +For dynamic data, one could choose to either have @emph{MHD} free the memory @code{page} points +to itself when it is not longer needed (by passing @code{MHD_RESPMEM_MUST_FREE}) or, alternatively, have the library to make and manage +its own copy of it (by passing @code{MHD_RESPMEM_MUST_COPY}). Naturally, this last option is the most expensive. + +@heading Exercises +@itemize @bullet +@item +While the server is running, use a program like @code{telnet} or @code{netcat} to connect to it.

Contains a list with the CA names that the server considers trusted. Normally we should send a certificate that is signed by one of these CAs. These names are DER encoded. To get a more meaningful value use the function @code{gnutls_x509_rdn_get()}. + +@item pk_algos +contains a list with server’s acceptable signature algorithms. The certificate returned should support the server’s given algorithms. + +@item pcert +should contain a single certificate and public or a list of them. + +@item pcert_length +is the size of the previous list. + +@item pkey +is the private key. +@end table +@end deftypefn + +A possible implementation of this callback would look like this: + +@verbatim +struct Hosts +{ + struct Hosts *next; + const char *hostname; + gnutls_pcert_st pcrt; + gnutls_privkey_t key; +}; + +static struct Hosts *hosts; + +int +sni_callback (gnutls_session_t session, + const gnutls_datum_t* req_ca_dn, + int nreqs, + const gnutls_pk_algorithm_t* pk_algos, + int pk_algos_length, + gnutls_pcert_st** pcert, + unsigned int *pcert_length, + gnutls_privkey_t * pkey) +{ + char name[256]; + size_t name_len; + struct Hosts *host; + unsigned int type; + + name_len = sizeof (name); + if (GNUTLS_E_SUCCESS != + gnutls_server_name_get (session, + name, + &name_len, + &type, + 0 /* index */)) + return -1; + for (host = hosts; NULL != host; host = host->next) + if (0 == strncmp (name, host->hostname, name_len)) + break; + if (NULL == host) + { + fprintf (stderr, + "Need certificate for %.*s\n", + (int) name_len, + name); + return -1; + } + fprintf (stderr, + "Returning certificate for %.*s\n", + (int) name_len, + name); + *pkey = host->key; + *pcert_length = 1; + *pcert = &host->pcrt; + return 0; +} +@end verbatim + +Note that MHD cannot offer passing a closure or any other additional information +to this callback, as the GnuTLS API unfortunately does not permit this at this +point. + +The @code{hosts} list can be initialized by loading the private keys and X.509 +certificats from disk as follows: + +@verbatim +static void +load_keys(const char *hostname, + const char *CERT_FILE, + const char *KEY_FILE) +{ + int ret; + gnutls_datum_t data; + struct Hosts *host; + + host = malloc (sizeof (struct Hosts)); + host->hostname = hostname; + host->next = hosts; + hosts = host; + + ret = gnutls_load_file (CERT_FILE, &data); + if (ret < 0) + { + fprintf (stderr, + "*** Error loading certificate file %s.\n", + CERT_FILE); + exit(1); + } + ret = + gnutls_pcert_import_x509_raw (&host->pcrt, &data, GNUTLS_X509_FMT_PEM, + 0); + if (ret < 0) + { + fprintf(stderr, + "*** Error loading certificate file: %s\n", + gnutls_strerror (ret)); + exit(1); + } + gnutls_free (data.data); + + ret = gnutls_load_file (KEY_FILE, &data); + if (ret < 0) + { + fprintf (stderr, + "*** Error loading key file %s.\n", + KEY_FILE); + exit(1); + } + + gnutls_privkey_init (&host->key); + ret = + gnutls_privkey_import_x509_raw (host->key, + &data, GNUTLS_X509_FMT_PEM, + NULL, 0); + if (ret < 0) + { + fprintf (stderr, + "*** Error loading key file: %s\n", + gnutls_strerror (ret)); + exit(1); + } + gnutls_free (data.data); +} +@end verbatim + +The code above was largely lifted from GnuTLS.

This +chapter discusses a first method of client's authentication and its +limits. + + A very simple approach feasible with the means already discussed +would be to expect the password in the _URI_ string before granting +access to the secured areas. The password could be separated from the +actual resource identifier by a certain character, thus the request line +might look like +GET /picture.png?mypassword + + In the rare situation where the client is customized enough and the +connection occurs through secured lines (e.g., a embedded device +directly attached to another via wire) and where the ability to embedd a +password in the URI or to pass on a URI with a password are desired, +this can be a reasonable choice. + + But when it is assumed that the user connecting does so with an +ordinary Internet browser, this implementation brings some problems +about. For example, the URI including the password stays in the address +field or at least in the history of the browser for anybody near enough +to see. It will also be inconvenient to add the password manually to +any new URI when the browser does not know how to compose this +automatically. + + At least the convenience issue can be addressed by employing the +simplest built-in password facilities of HTTP compliant browsers, hence +we want to start there. It will however turn out to have still severe +weaknesses in terms of security which need consideration. + + Before we will start implementing _Basic Authentication_ as described +in _RFC 2617_, we should finally abandon the bad practice of responding +every request the first time our callback is called for a given +connection. This is becoming more important now because the client and +the server will have to talk in a more bi-directional way than before to + + But how can we tell whether the callback has been called before for +the particular connection? Initially, the pointer this parameter +references is set by _MHD_ in the callback. But it will also be +"remembered" on the next call (for the same connection). Thus, we will +generate no response until the parameter is non-null--implying the +callback was called before at least once. We do not need to share +information between different calls of the callback, so we can set the +parameter to any adress that is assured to be not null. The pointer to +the 'connection' structure will be pointing to a legal address, so we +take this. + + The first time 'answer_to_connection' is called, we will not even +look at the headers. + +static int +answer_to_connection (void *cls, struct MHD_Connection *connection, + const char *url, const char *method, const char *version, + const char *upload_data, size_t *upload_data_size, + void **con_cls) +{ + if (0 != strcmp(method, "GET")) return MHD_NO; + if (NULL == *con_cls) {*con_cls = connection; return MHD_YES;} + + ... + /* else respond accordingly */ + ... +} + + Note how we lop off the connection on the first condition (no "GET" +request), but return asking for more on the other one with 'MHD_YES'. +With this minor change, we can proceed to implement the actual +authentication process. + +Request for authentication +========================== + +Let us assume we had only files not intended to be handed out without +the correct username/password, so every "GET" request will be +challenged. _RFC 2617_ describes how the server shall ask for +authentication by adding a _WWW-Authenticate_ response header with the +name of the _realm_ protected. MHD can generate and queue such a +failure response for you using the 'MHD_queue_basic_auth_fail_response' +API. The only thing you need to do is construct a response with the +error page to be shown to the user if he aborts basic authentication. +But first, you should check if the proper credentials were already +supplied using the 'MHD_basic_auth_get_username_password' call. + + Your code would then look like this: +static int +answer_to_connection (void *cls, struct MHD_Connection *connection, + const char *url, const char *method, + const char *version, const char *upload_data, + size_t *upload_data_size, void **con_cls) +{ + char *user; + char *pass; + int fail; + struct MHD_Response *response; + + if (0 != strcmp (method, MHD_HTTP_METHOD_GET)) + return MHD_NO; + if (NULL == *con_cls) + { + *con_cls = connection; + return MHD_YES; + } + pass = NULL; + user = MHD_basic_auth_get_username_password (connection, &pass); + fail = ( (user == NULL) || + (0 != strcmp (user, "root")) || + (0 != strcmp (pass, "pa$$w0rd") ) ); + if (user != NULL) free (user); + if (pass != NULL) free (pass); + if (fail) + { + const char *page = "Go away."; + response = + MHD_create_response_from_buffer (strlen (page), (void *) page, + MHD_RESPMEM_PERSISTENT); + ret = MHD_queue_basic_auth_fail_response (connection, + "my realm", + response); + } + else + { + const char *page = "A secret."; + response = + MHD_create_response_from_buffer (strlen (page), (void *) page, + MHD_RESPMEM_PERSISTENT); + ret = MHD_queue_response (connection, MHD_HTTP_OK, response); + } + MHD_destroy_response (response); + return ret; +} + + See the 'examples' directory for the complete example file. + +Remarks +======= + +For a proper server, the conditional statements leading to a return of +'MHD_NO' should yield a response with a more precise status code instead +of silently closing the connection. For example, failures of memory +allocation are best reported as _internal server error_ and unexpected +authentication methods as _400 bad request_. + +Exercises +========= + + * Make the server respond to wrong credentials (but otherwise + well-formed requests) with the recommended _401 unauthorized_ + status code. If the client still does not authenticate correctly + within the same connection, close it and store the client's IP + address for a certain time. (It is OK to check for expiration not + until the main thread wakes up again on the next connection.) If + the client fails authenticating three times during this period, add + it to another list for which the 'AcceptPolicyCallback' function + denies connection (temporally). + + * With the network utility 'netcat' connect and log the response of a + "GET" request as you did in the exercise of the first example, this + time to a file. Now stop the server and let _netcat_ listen on the + same port the server used to listen on and have it fake being the + proper server by giving the file's content as the response (e.g. + 'cat log | nc -l -p 8888'). Pretending to think your were + connecting to the actual server, browse to the eavesdropper and + give the correct credentials. + + Copy and paste the encoded string you see in 'netcat''s output to + some of the Base64 decode tools available online and see how both + the user's name and password could be completely restored. + + +File: libmicrohttpd-tutorial.info, Node: Processing POST data, Next: Improved processing of POST data, Prev: Supporting basic authentication, Up: Top + +6 Processing POST data +********************** + +The previous chapters already have demonstrated a variety of +possibilities to send information to the HTTP server, but it is not +recommended that the _GET_ method is used to alter the way the server +operates. To induce changes on the server, the _POST_ method is +preferred over and is much more powerful than _GET_ and will be +introduced in this chapter. + + We are going to write an application that asks for the visitor's name +and, after the user has posted it, composes an individual response text. +Even though it was not mandatory to use the _POST_ method here, as there +is no permanent change caused by the POST, it is an illustrative example +on how to share data between different functions for the same +connection. Furthermore, the reader should be able to extend it easily. + +GET request +=========== + +When the first _GET_ request arrives, the server shall respond with a +HTML page containing an edit field for the name. + +const char* askpage = "\ + What's your name, Sir?
\ + \ + \ + "; + + The 'action' entry is the _URI_ to be called by the browser when +posting, and the 'name' will be used later to be sure it is the +editbox's content that has been posted. + + We also prepare the answer page, where the name is to be filled in +later, and an error page as the response for anything but proper _GET_ +and _POST_ requests: + +const char* greatingpage="

Welcome, %s!

"; + +const char* errorpage="This doesn't seem to be right."; + + Whenever we need to send a page, we use an extra function 'int +send_page(struct MHD_Connection *connection, const char* page)' for +this, which does not contain anything new and whose implementation is +therefore not discussed further in the tutorial. + +POST request +============ + +Posted data can be of arbitrary and considerable size; for example, if a +user uploads a big image to the server. Similar to the case of the +header fields, there may also be different streams of posted data, such +as one containing the text of an editbox and another the state of a +button. Likewise, we will have to register an iterator function that is +going to be called maybe several times not only if there are different +POSTs but also if one POST has only been received partly yet and needs +processing before another chunk can be received. + + Such an iterator function is called by a _postprocessor_, which must +be created upon arriving of the post request. We want the iterator +function to read the first post data which is tagged 'name' and to +create an individual greeting string based on the template and the name. +But in order to pass this string to other functions and still be able to +differentiate different connections, we must first define a structure to +share the information, holding the most import entries. + +struct connection_info_struct +{ + int connectiontype; + char *answerstring; + struct MHD_PostProcessor *postprocessor; +}; + + With these information available to the iterator function, it is able +to fulfill its task. Once it has composed the greeting string, it +returns 'MHD_NO' to inform the post processor that it does not need to +be called again. Note that this function does not handle processing of +data for the same 'key'. If we were to expect that the name will be +posted in several chunks, we had to expand the namestring dynamically as +additional parts of it with the same 'key' came in. But in this +example, the name is assumed to fit entirely inside one single packet. + +static int +iterate_post (void *coninfo_cls, enum MHD_ValueKind kind, const char *key, + const char *filename, const char *content_type, + const char *transfer_encoding, const char *data, + uint64_t off, size_t size) +{ + struct connection_info_struct *con_info = coninfo_cls; + + if (0 == strcmp (key, "name")) + { + if ((size > 0) && (size <= MAXNAMESIZE)) + { + char *answerstring; + answerstring = malloc (MAXANSWERSIZE); + if (!answerstring) return MHD_NO; + + snprintf (answerstring, MAXANSWERSIZE, greatingpage, data); + con_info->answerstring = answerstring; + } + else con_info->answerstring = NULL; + + return MHD_NO; + } + + return MHD_YES; +} + + Once a connection has been established, it can be terminated for many +reasons. As these reasons include unexpected events, we have to +register another function that cleans up any resources that might have +been allocated for that connection by us, namely the post processor and +the greetings string. This cleanup function must take into account that +it will also be called for finished requests other than _POST_ requests. + +void request_completed (void *cls, struct MHD_Connection *connection, + void **con_cls, + enum MHD_RequestTerminationCode toe) +{ + struct connection_info_struct *con_info = *con_cls; + + if (NULL == con_info) return; + if (con_info->connectiontype == POST) + { + MHD_destroy_post_processor (con_info->postprocessor); + if (con_info->answerstring) free (con_info->answerstring); + } + + free (con_info); + *con_cls = NULL; +} + + _GNU libmicrohttpd_ is informed that it shall call the above function +when the daemon is started in the main function. + +... +daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY, PORT, NULL, NULL, + &answer_to_connection, NULL, + MHD_OPTION_NOTIFY_COMPLETED, &request_completed, NULL, + MHD_OPTION_END); +... + +Request handling +================ + +With all other functions prepared, we can now discuss the actual request +handling. + + On the first iteration for a new request, we start by allocating a +new instance of a 'struct connection_info_struct' structure, which will +store all necessary information for later iterations and other +functions. + +static int +answer_to_connection (void *cls, struct MHD_Connection *connection, + const char *url, + const char *method, const char *version, + const char *upload_data, + size_t *upload_data_size, void **con_cls) +{ + if(NULL == *con_cls) + { + struct connection_info_struct *con_info; + + con_info = malloc (sizeof (struct connection_info_struct)); + if (NULL == con_info) return MHD_NO; + con_info->answerstring = NULL; + + If the new request is a _POST_, the postprocessor must be created +now.

In this chapter, we are going to +discuss a more advanced server program that allows clients to upload a +file in order to have it stored on the server's filesystem. The server +shall also watch and limit the number of clients concurrently uploading, +responding with a proper busy message if necessary. + +Prepared answers +================ + +We choose to operate the server with the 'SELECT_INTERNALLY' method. +This makes it easier to synchronize the global states at the cost of +possible delays for other connections if the processing of a request is +too slow.

We use a +simple example where the user submits multiple forms and the server is +supposed to accumulate state from all of these forms. Naturally, as +this is a network protocol, our session mechanism must support having +many users with many concurrent sessions at the same time. + + In order to track users, we use a simple session cookie. A session +cookie expires when the user closes the browser. Changing from session +cookies to persistent cookies only requires adding an expiration time to +the cookie. The server creates a fresh session cookie whenever a +request without a cookie is received, or if the supplied session cookie +is not known to the server. + +Looking up the cookie +===================== + +Since MHD parses the HTTP cookie header for us, looking up an existing +cookie is straightforward: + +const char *value; + +value = MHD_lookup_connection_value (connection, + MHD_COOKIE_KIND, + "KEY"); + + Here, "KEY" is the name we chose for our session cookie. + +Setting the cookie header +========================= + +MHD requires the user to provide the full cookie format string in order +to set cookies. In order to generate a unique cookie, our example +creates a random 64-character text string to be used as the value of the +cookie: + +char value[128]; +char raw_value[65]; + +for (unsigned int i=0;i openssl genrsa -out server.key 1024 + + In addition to the key, a certificate describing the server in human +readable tokens is also needed. This certificate will be attested with +our aforementioned key. In this way, we obtain a self-signed +certificate, valid for one year. + +> openssl req -days 365 -out server.pem -new -x509 -key server.key + + To avoid unnecessary error messages in the browser, the certificate +needs to have a name that matches the _URI_, for example, "localhost" or +the domain. If you plan to have a publicly reachable server, you will +need to ask a trusted third party, called _Certificate Authority_, or +_CA_, to attest the certificate for you. This way, any visitor can make +sure the server's identity is real. + + Whether the server's certificate is signed by us or a third party, +once it has been accepted by the client, both sides will be +communicating over encrypted channels. From this point on, it is the +client's turn to authenticate itself. But this has already been +implemented in the basic authentication scheme. + +Changing the source code +======================== + +We merely have to extend the server program so that it loads the two +files into memory, + +int +main () +{ + struct MHD_Daemon *daemon; + char *key_pem; + char *cert_pem; + + key_pem = load_file (SERVERKEYFILE); + cert_pem = load_file (SERVERCERTFILE); + + if ((key_pem == NULL) || (cert_pem == NULL)) + { + printf ("The key/certificate files could not be read.\n"); + return 1; + } + + and then we point the _MHD_ daemon to it upon initalization. + + daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY | MHD_USE_SSL, + PORT, NULL, NULL, + &answer_to_connection, NULL, + MHD_OPTION_HTTPS_MEM_KEY, key_pem, + MHD_OPTION_HTTPS_MEM_CERT, cert_pem, + MHD_OPTION_END); + + if (NULL == daemon) + { + printf ("%s\n", cert_pem); + + free (key_pem); + free (cert_pem); + + return 1; + } + + The rest consists of little new besides some additional memory +cleanups. + + getchar (); + + MHD_stop_daemon (daemon); + free (key_pem); + free (cert_pem); + + return 0; +} + + The rather unexciting file loader can be found in the complete +example 'tlsauthentication.c'. + +Remarks +======= + + * While the standard _HTTP_ port is 80, it is 443 for _HTTPS_. The + common internet browsers assume standard _HTTP_ if they are asked + to access other ports than these. Therefore, you will have to type + 'https://localhost:8888' explicitly when you test the example, or + the browser will not know how to handle the answer properly. + + * The remaining weak point is the question how the server will be + trusted initially. Either a _CA_ signs the certificate or the + client obtains the key over secure means. Anyway, the clients have + to be aware (or configured) that they should not accept + certificates of unknown origin. + + * The introduced method of certificates makes it mandatory to set an + expiration date--making it less feasible to hardcode certificates + in embedded devices. + + * The cryptographic facilities consume memory space and computing + time. For this reason, websites usually consists both of + uncritically _HTTP_ parts and secured _HTTPS_. + +Client authentication +===================== + +You can also use MHD to authenticate the client via SSL/TLS certificates +(as an alternative to using the password-based Basic or Digest +authentication). To do this, you will need to link your application +against _gnutls_. Next, when you start the MHD daemon, you must specify +the root CA that you're willing to trust: + daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY | MHD_USE_SSL, + PORT, NULL, NULL, + &answer_to_connection, NULL, + MHD_OPTION_HTTPS_MEM_KEY, key_pem, + MHD_OPTION_HTTPS_MEM_CERT, cert_pem, + MHD_OPTION_HTTPS_MEM_TRUST, root_ca_pem, + MHD_OPTION_END); + + With this, you can then obtain client certificates for each session. +In order to obtain the identity of the client, you first need to obtain +the raw GnuTLS session handle from _MHD_ using +'MHD_get_connection_info'. + +#include +#include + +gnutls_session_t tls_session; +union MHD_ConnectionInfo *ci; + +ci = MHD_get_connection_info (connection, + MHD_CONNECTION_INFO_GNUTLS_SESSION); +tls_session = ci->tls_session; + + You can then extract the client certificate: + +/** + * Get the client's certificate + * + * @param tls_session the TLS session + * @return NULL if no valid client certificate could be found, a pointer + * to the certificate if found + */ +static gnutls_x509_crt_t +get_client_certificate (gnutls_session_t tls_session) +{ + unsigned int listsize; + const gnutls_datum_t * pcert; + gnutls_certificate_status_t client_cert_status; + gnutls_x509_crt_t client_cert; + + if (tls_session == NULL) + return NULL; + if (gnutls_certificate_verify_peers2(tls_session, + &client_cert_status)) + return NULL; + pcert = gnutls_certificate_get_peers(tls_session, + &listsize); + if ( (pcert == NULL) || + (listsize == 0)) + { + fprintf (stderr, + "Failed to retrieve client certificate chain\n"); + return NULL; + } + if (gnutls_x509_crt_init(&client_cert)) + { + fprintf (stderr, + "Failed to initialize client certificate\n"); + return NULL; + } + /* Note that by passing values between 0 and listsize here, you + can get access to the CA's certs */ + if (gnutls_x509_crt_import(client_cert, + &pcert[0], + GNUTLS_X509_FMT_DER)) + { + fprintf (stderr, + "Failed to import client certificate\n"); + gnutls_x509_crt_deinit(client_cert); + return NULL; + } + return client_cert; +} + + Using the client certificate, you can then get the client's +distinguished name and alternative names: + +/** + * Get the distinguished name from the client's certificate + * + * @param client_cert the client certificate + * @return NULL if no dn or certificate could be found, a pointer + * to the dn if found + */ +char * +cert_auth_get_dn(gnutls_x509_crt_c client_cert) +{ + char* buf; + size_t lbuf; + + lbuf = 0; + gnutls_x509_crt_get_dn(client_cert, NULL, &lbuf); + buf = malloc(lbuf); + if (buf == NULL) + { + fprintf (stderr, + "Failed to allocate memory for certificate dn\n"); + return NULL; + } + gnutls_x509_crt_get_dn(client_cert, buf, &lbuf); + return buf; +} + + +/** + * Get the alternative name of specified type from the client's certificate + * + * @param client_cert the client certificate + * @param nametype The requested name type + * @param index The position of the alternative name if multiple names are + * matching the requested type, 0 for the first matching name + * @return NULL if no matching alternative name could be found, a pointer + * to the alternative name if found + */ +char * +MHD_cert_auth_get_alt_name(gnutls_x509_crt_t client_cert, + int nametype, + unsigned int index) +{ + char* buf; + size_t lbuf; + unsigned int seq; + unsigned int subseq; + unsigned int type; + int result; + + subseq = 0; + for (seq=0;;seq++) + { + lbuf = 0; + result = gnutls_x509_crt_get_subject_alt_name2(client_cert, seq, NULL, &lbuf, + &type, NULL); + if (result == GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE) + return NULL; + if (nametype != (int) type) + continue; + if (subseq == index) + break; + subseq++; + } + buf = malloc(lbuf); + if (buf == NULL) + { + fprintf (stderr, + "Failed to allocate memory for certificate alt name\n"); + return NULL; + } + result = gnutls_x509_crt_get_subject_alt_name2(client_cert, + seq, + buf, + &lbuf, + NULL, NULL); + if (result != nametype) + { + fprintf (stderr, + "Unexpected return value from gnutls: %d\n", + result); + free (buf); + return NULL; + } + return buf; +} + + Finally, you should release the memory associated with the client +certificate: + +gnutls_x509_crt_deinit (client_cert); + +Using TLS Server Name Indication (SNI) +====================================== + +SNI enables hosting multiple domains under one IP address with TLS. So +SNI is the TLS-equivalent of virtual hosting. To use SNI with MHD, you +need at least GnuTLS 3.0. The main change compared to the simple +hosting of one domain is that you need to provide a callback instead of +the key and certificate. For example, when you start the MHD daemon, +you could do this: + daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY | MHD_USE_SSL, + PORT, NULL, NULL, + &answer_to_connection, NULL, + MHD_OPTION_HTTPS_CERT_CALLBACK, &sni_callback, + MHD_OPTION_END); + Here, 'sni_callback' is the name of a function that you will have to +implement to retrieve the X.509 certificate for an incoming connection. +The callback has type 'gnutls_certificate_retrieve_function2' and is +documented in the GnuTLS API for the +'gnutls_certificate_set_retrieve_function2' as follows: + + -- Function Pointer: int *gnutls_certificate_retrieve_function2 + (gnutls_session_t, const gnutls_datum_t* req_ca_dn, int nreqs, + const gnutls_pk_algorithm_t* pk_algos, int pk_algos_length, + gnutls_pcert_st** pcert, unsigned int *pcert_length, + gnutls_privkey_t * pkey) + + REQ_CA_CERT + is only used in X.509 certificates. Contains a list with the + CA names that the server considers trusted. Normally we + should send a certificate that is signed by one of these CAs. + These names are DER encoded. To get a more meaningful value + use the function 'gnutls_x509_rdn_get()'. + + PK_ALGOS + contains a list with server’s acceptable signature algorithms. + The certificate returned should support the server’s given + algorithms. + + PCERT + should contain a single certificate and public or a list of + them. + + PCERT_LENGTH + is the size of the previous list. + + PKEY + is the private key. + + A possible implementation of this callback would look like this: + +struct Hosts +{ + struct Hosts *next; + const char *hostname; + gnutls_pcert_st pcrt; + gnutls_privkey_t key; +}; + +static struct Hosts *hosts; + +int +sni_callback (gnutls_session_t session, + const gnutls_datum_t* req_ca_dn, + int nreqs, + const gnutls_pk_algorithm_t* pk_algos, + int pk_algos_length, + gnutls_pcert_st** pcert, + unsigned int *pcert_length, + gnutls_privkey_t * pkey) +{ + char name[256]; + size_t name_len; + struct Hosts *host; + unsigned int type; + + name_len = sizeof (name); + if (GNUTLS_E_SUCCESS != + gnutls_server_name_get (session, + name, + &name_len, + &type, + 0 /* index */)) + return -1; + for (host = hosts; NULL != host; host = host->next) + if (0 == strncmp (name, host->hostname, name_len)) + break; + if (NULL == host) + { + fprintf (stderr, + "Need certificate for %.*s\n", + (int) name_len, + name); + return -1; + } + fprintf (stderr, + "Returning certificate for %.*s\n", + (int) name_len, + name); + *pkey = host->key; + *pcert_length = 1; + *pcert = &host->pcrt; + return 0; +} + + Note that MHD cannot offer passing a closure or any other additional +information to this callback, as the GnuTLS API unfortunately does not +permit this at this point. + + The 'hosts' list can be initialized by loading the private keys and +X.509 certificats from disk as follows: + +static void +load_keys(const char *hostname, + const char *CERT_FILE, + const char *KEY_FILE) +{ + int ret; + gnutls_datum_t data; + struct Hosts *host; + + host = malloc (sizeof (struct Hosts)); + host->hostname = hostname; + host->next = hosts; + hosts = host; + + ret = gnutls_load_file (CERT_FILE, &data); + if (ret < 0) + { + fprintf (stderr, + "*** Error loading certificate file %s.\n", + CERT_FILE); + exit(1); + } + ret = + gnutls_pcert_import_x509_raw (&host->pcrt, &data, GNUTLS_X509_FMT_PEM, + 0); + if (ret < 0) + { + fprintf(stderr, + "*** Error loading certificate file: %s\n", + gnutls_strerror (ret)); + exit(1); + } + gnutls_free (data.data); + + ret = gnutls_load_file (KEY_FILE, &data); + if (ret < 0) + { + fprintf (stderr, + "*** Error loading key file %s.\n", + KEY_FILE); + exit(1); + } + + gnutls_privkey_init (&host->key); + ret = + gnutls_privkey_import_x509_raw (host->key, + &data, GNUTLS_X509_FMT_PEM, + NULL, 0); + if (ret < 0) + { + fprintf (stderr, + "*** Error loading key file: %s\n", + gnutls_strerror (ret)); + exit(1); + } + gnutls_free (data.data); +} + + The code above was largely lifted from GnuTLS.

If you + distribute a large enough number of copies you must also follow the + conditions in section 3. + + You may also lend copies, under the same conditions stated above, + and you may publicly display copies. + + 3. COPYING IN QUANTITY + + If you publish printed copies (or copies in media that commonly + have printed covers) of the Document, numbering more than 100, and + the Document's license notice requires Cover Texts, you must + enclose the copies in covers that carry, clearly and legibly, all + these Cover Texts: Front-Cover Texts on the front cover, and + Back-Cover Texts on the back cover. Both covers must also clearly + and legibly identify you as the publisher of these copies. The + front cover must present the full title with all words of the title + equally prominent and visible. You may add other material on the + covers in addition. Copying with changes limited to the covers, as + long as they preserve the title of the Document and satisfy these + conditions, can be treated as verbatim copying in other respects. + + If the required texts for either cover are too voluminous to fit + legibly, you should put the first ones listed (as many as fit + reasonably) on the actual cover, and continue the rest onto + adjacent pages. + + If you publish or distribute Opaque copies of the Document + numbering more than 100, you must either include a machine-readable + Transparent copy along with each Opaque copy, or state in or with + each Opaque copy a computer-network location from which the general + network-using public has access to download using public-standard + network protocols a complete Transparent copy of the Document, free + of added material. If you use the latter option, you must take + reasonably prudent steps, when you begin distribution of Opaque + copies in quantity, to ensure that this Transparent copy will + remain thus accessible at the stated location until at least one + year after the last time you distribute an Opaque copy (directly or + through your agents or retailers) of that edition to the public. + + It is requested, but not required, that you contact the authors of + the Document well before redistributing any large number of copies, + to give them a chance to provide you with an updated version of the + Document. + + 4. MODIFICATIONS + + You may copy and distribute a Modified Version of the Document + under the conditions of sections 2 and 3 above, provided that you + release the Modified Version under precisely this License, with the + Modified Version filling the role of the Document, thus licensing + distribution and modification of the Modified Version to whoever + possesses a copy of it. In addition, you must do these things in + the Modified Version: + + A. Use in the Title Page (and on the covers, if any) a title + distinct from that of the Document, and from those of previous + versions (which should, if there were any, be listed in the + History section of the Document). You may use the same title + as a previous version if the original publisher of that + version gives permission. + + B. List on the Title Page, as authors, one or more persons or + entities responsible for authorship of the modifications in + the Modified Version, together with at least five of the + principal authors of the Document (all of its principal + authors, if it has fewer than five), unless they release you + from this requirement. + + C. State on the Title page the name of the publisher of the + Modified Version, as the publisher. + + D. Preserve all the copyright notices of the Document. + + E. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. + + F. Include, immediately after the copyright notices, a license + notice giving the public permission to use the Modified + Version under the terms of this License, in the form shown in + the Addendum below. + + G. Preserve in that license notice the full lists of Invariant + Sections and required Cover Texts given in the Document's + license notice. + + H. Include an unaltered copy of this License. + + I. Preserve the section Entitled "History", Preserve its Title, + and add to it an item stating at least the title, year, new + authors, and publisher of the Modified Version as given on the + Title Page. If there is no section Entitled "History" in the + Document, create one stating the title, year, authors, and + publisher of the Document as given on its Title Page, then add + an item describing the Modified Version as stated in the + previous sentence. + + J. Preserve the network location, if any, given in the Document + for public access to a Transparent copy of the Document, and + likewise the network locations given in the Document for + previous versions it was based on. These may be placed in the + "History" section. You may omit a network location for a work + that was published at least four years before the Document + itself, or if the original publisher of the version it refers + to gives permission. + + K. For any section Entitled "Acknowledgements" or "Dedications", + Preserve the Title of the section, and preserve in the section + all the substance and tone of each of the contributor + acknowledgements and/or dedications given therein. + + L. Preserve all the Invariant Sections of the Document, unaltered + in their text and in their titles. Section numbers or the + equivalent are not considered part of the section titles. + + M. Delete any section Entitled "Endorsements". Such a section + may not be included in the Modified Version. + + N. Do not retitle any existing section to be Entitled + "Endorsements" or to conflict in title with any Invariant + Section. + + O. Preserve any Warranty Disclaimers. + + If the Modified Version includes new front-matter sections or + appendices that qualify as Secondary Sections and contain no + material copied from the Document, you may at your option designate + some or all of these sections as invariant. To do this, add their + titles to the list of Invariant Sections in the Modified Version's + license notice. These titles must be distinct from any other + section titles. + + You may add a section Entitled "Endorsements", provided it contains + nothing but endorsements of your Modified Version by various + parties--for example, statements of peer review or that the text + has been approved by an organization as the authoritative + definition of a standard. + + You may add a passage of up to five words as a Front-Cover Text, + and a passage of up to 25 words as a Back-Cover Text, to the end of + the list of Cover Texts in the Modified Version. Only one passage + of Front-Cover Text and one of Back-Cover Text may be added by (or + through arrangements made by) any one entity. If the Document + already includes a cover text for the same cover, previously added + by you or by arrangement made by the same entity you are acting on + behalf of, you may not add another; but you may replace the old + one, on explicit permission from the previous publisher that added + the old one. + + The author(s) and publisher(s) of the Document do not by this + License give permission to use their names for publicity for or to + assert or imply endorsement of any Modified Version. + + 5. COMBINING DOCUMENTS + + You may combine the Document with other documents released under + this License, under the terms defined in section 4 above for + modified versions, provided that you include in the combination all + of the Invariant Sections of all of the original documents, + unmodified, and list them all as Invariant Sections of your + combined work in its license notice, and that you preserve all + their Warranty Disclaimers. + + The combined work need only contain one copy of this License, and + multiple identical Invariant Sections may be replaced with a single + copy. If there are multiple Invariant Sections with the same name + but different contents, make the title of each such section unique + by adding at the end of it, in parentheses, the name of the + original author or publisher of that section if known, or else a + unique number. Make the same adjustment to the section titles in + the list of Invariant Sections in the license notice of the + combined work. + + In the combination, you must combine any sections Entitled + "History" in the various original documents, forming one section + Entitled "History"; likewise combine any sections Entitled + "Acknowledgements", and any sections Entitled "Dedications". You + must delete all sections Entitled "Endorsements." + + 6. COLLECTIONS OF DOCUMENTS + + You may make a collection consisting of the Document and other + documents released under this License, and replace the individual + copies of this License in the various documents with a single copy + that is included in the collection, provided that you follow the + rules of this License for verbatim copying of each of the documents + in all other respects. + + You may extract a single document from such a collection, and + distribute it individually under this License, provided you insert + a copy of this License into the extracted document, and follow this + License in all other respects regarding verbatim copying of that + document. + + 7. AGGREGATION WITH INDEPENDENT WORKS + + A compilation of the Document or its derivatives with other + separate and independent documents or works, in or on a volume of a + storage or distribution medium, is called an "aggregate" if the + copyright resulting from the compilation is not used to limit the + legal rights of the compilation's users beyond what the individual + works permit. When the Document is included in an aggregate, this + License does not apply to the other works in the aggregate which + are not themselves derivative works of the Document. + + If the Cover Text requirement of section 3 is applicable to these + copies of the Document, then if the Document is less than one half + of the entire aggregate, the Document's Cover Texts may be placed + on covers that bracket the Document within the aggregate, or the + electronic equivalent of covers if the Document is in electronic + form. Otherwise they must appear on printed covers that bracket + the whole aggregate. + + 8. TRANSLATION + + Translation is considered a kind of modification, so you may + distribute translations of the Document under the terms of section + 4. Replacing Invariant Sections with translations requires special + permission from their copyright holders, but you may include + translations of some or all Invariant Sections in addition to the + original versions of these Invariant Sections. You may include a + translation of this License, and all the license notices in the + Document, and any Warranty Disclaimers, provided that you also + include the original English version of this License and the + original versions of those notices and disclaimers. In case of a + disagreement between the translation and the original version of + this License or a notice or disclaimer, the original version will + prevail. + + If a section in the Document is Entitled "Acknowledgements", + "Dedications", or "History", the requirement (section 4) to + Preserve its Title (section 1) will typically require changing the + actual title. + + 9. TERMINATION + + You may not copy, modify, sublicense, or distribute the Document + except as expressly provided under this License. Any attempt + otherwise to copy, modify, sublicense, or distribute it is void, + and will automatically terminate your rights under this License. + + However, if you cease all violation of this License, then your + license from a particular copyright holder is reinstated (a) + provisionally, unless and until the copyright holder explicitly and + finally terminates your license, and (b) permanently, if the + copyright holder fails to notify you of the violation by some + reasonable means prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is + reinstated permanently if the copyright holder notifies you of the + violation by some reasonable means, this is the first time you have + received notice of violation of this License (for any work) from + that copyright holder, and you cure the violation prior to 30 days + after your receipt of the notice. + + Termination of your rights under this section does not terminate + the licenses of parties who have received copies or rights from you + under this License. If your rights have been terminated and not + permanently reinstated, receipt of a copy of some or all of the + same material does not give you any rights to use it. + + 10. FUTURE REVISIONS OF THIS LICENSE + + The Free Software Foundation may publish new, revised versions of + the GNU Free Documentation License from time to time. Such new + versions will be similar in spirit to the present version, but may + differ in detail to address new problems or concerns. See + . + + Each version of the License is given a distinguishing version + number. If the Document specifies that a particular numbered + version of this License "or any later version" applies to it, you + have the option of following the terms and conditions either of + that specified version or of any later version that has been + published (not as a draft) by the Free Software Foundation. If the + Document does not specify a version number of this License, you may + choose any version ever published (not as a draft) by the Free + Software Foundation. If the Document specifies that a proxy can + decide which future versions of this License can be used, that + proxy's public statement of acceptance of a version permanently + authorizes you to choose that version for the Document. + + 11. RELICENSING + + "Massive Multiauthor Collaboration Site" (or "MMC Site") means any + World Wide Web server that publishes copyrightable works and also + provides prominent facilities for anybody to edit those works. A + public wiki that anybody can edit is an example of such a server. + A "Massive Multiauthor Collaboration" (or "MMC") contained in the + site means any set of copyrightable works thus published on the MMC + site. + + "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 + license published by Creative Commons Corporation, a not-for-profit + corporation with a principal place of business in San Francisco, + California, as well as future copyleft versions of that license + published by that same organization. + + "Incorporate" means to publish or republish a Document, in whole or + in part, as part of another Document. + + An MMC is "eligible for relicensing" if it is licensed under this + License, and if all works that were first published under this + License somewhere other than this MMC, and subsequently + incorporated in whole or in part into the MMC, (1) had no cover + texts or invariant sections, and (2) were thus incorporated prior + to November 1, 2008. + + The operator of an MMC Site may republish an MMC contained in the + site under CC-BY-SA on the same site at any time before August 1, + 2009, provided the MMC is eligible for relicensing. + +ADDENDUM: How to use this License for your documents +==================================================== + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and license +notices just after the title page: + + Copyright (C) YEAR YOUR NAME. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.3 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover + Texts.

MHD +is a small HTTP daemon library. As such, it does not have any API +for logging errors (you can only enable or disable logging to stderr). +Also, it may not support all of the HTTP features directly, where +applicable, portions of HTTP may have to be handled by clients of the +library. + +The library is supposed to handle everything that it must handle +(because the API would not allow clients to do this), such as basic +connection management. However, detailed interpretations of headers, +such as range requests, are left to the main application. In +particular, if an application developer wants to support range +requests, he needs to explicitly indicate support in responses and +also explicitly parse the range header and generate a response (for +example, using the @code{MHD_create_response_from_fd_at_offset} call +to serve ranges from a file). MHD does understands headers that +control connection management (specifically, @code{Connection: close} +and @code{Expect: 100 continue} are understood and handled +automatically). @code{Connection: upgrade} is supported by passing +control over the socket (or something that behaves like the real +socket in the case of TLS) to the application (after sending the +desired HTTP response header). + +MHD largely ignores the semantics of the different HTTP methods, +so clients are left to handle those. One exception is that MHD does +understand @code{HEAD} and will only send the headers of the response +and not the body, even if the client supplied a body. (In fact, +clients do need to construct a response with the correct length, even +for @code{HEAD} request.) + +MHD understands @code{POST} data and is able to decode certain +formats (at the moment only @code{application/x-www-form-urlencoded} +and @code{multipart/form-data}) using the post processor API. The +data stream of a POST is also provided directly to the main +application, so unsupported encodings could still be processed, just +not conveniently by MHD. + +The header file defines various constants used by the HTTP protocol. +This does not mean that MHD actually interprets all of these values. +The provided constants are exported as a convenience for users of the +library. MHD does not verify that transmitted HTTP headers are +part of the standard specification; users of the library are free to +define their own extensions of the HTTP standard and use those with +MHD. + +All functions are guaranteed to be completely reentrant and +thread-safe. MHD checks for allocation failures and tries to +recover gracefully (for example, by closing the connection). +Additionally, clients can specify resource limits on the overall +number of connections, number of connections per IP address and memory +used per connection to avoid resource exhaustion. + +@section Scope + +MHD is currently used in a wide range of implementations. +Examples based on reports we've received from developers include: +@itemize +@item Embedded HTTP server on a cortex M3 (128 KB code space) +@item Large-scale multimedia server (reportedly serving at the + simulator limit of 7.5 GB/s) +@item Administrative console (via HTTP/HTTPS) for network appliances +@c If you have other interesting examples, please let us know +@end itemize + +@section Thread modes and event loops +@cindex poll +@cindex epoll +@cindex select + +MHD supports four basic thread modes and up to three event loop +styles. + +The four basic thread modes are external sockets polling (MHD creates +no threads, event loop is fully managed by the application), internal +polling (MHD creates one thread for all connections), polling in +thread pool (MHD creates a thread pool which is used to process all +connections) and thread-per-connection (MHD creates one thread for +listen sockets and then one thread per accepted connection). + +These thread modes are then combined with the evet loop styles +(polling function type). MHD support select, poll and epoll. select +is available on all platforms, epoll and poll may not be available on +some platforms. Note that it is possible to combine MHD using epoll +with an external select-based event loop. + +The default (if no other option is passed) is ``external select''. +The highest performance can typically be obtained with a thread pool +using @code{epoll}. Apache Benchmark (ab) was used to compare the +performance of @code{select} and @code{epoll} when using a thread pool +and a large number of connections. @ref{fig:performance} shows the +resulting plot from the @code{benchmark.c} example, which measures the +latency between an incoming request and the completion of the +transmission of the response. In this setting, the @code{epoll} +thread pool with four threads was able to handle more than 45,000 +connections per second on loopback (with Apache Benchmark running +three processes on the same machine). +@cindex performance + + +@float Figure,fig:performance +@image{libmicrohttpd_performance_data,400pt,300pt,Data,.png} +@caption{Performance measurements for select vs. epoll (with thread-pool).} +@end float + + +Not all combinations of thread modes and event loop styles are +supported. This is partially to keep the API simple, and partially +because some combinations simply make no sense as others are strictly +superior. Note that the choice of style depends first of all on the +application logic, and then on the performance requirements. +Applications that perform a blocking operation while handling a +request within the callbacks from MHD must use a thread per +connection. This is typically rather costly. Applications that do +not support threads or that must run on embedded devices without +thread-support must use the external mode. Using @code{epoll} is only +supported on some platform, thus portable applications must at least +have a fallback option available. @ref{tbl:supported} lists the sane +combinations. + +@float Table,tbl:supported +@multitable {@b{thread-per-connection}} {@b{select}} {@b{poll}} {@b{epoll}} +@item @tab @b{select} @tab @b{poll} @tab @b{epoll} +@item @b{external} @tab yes @tab no @tab yes +@item @b{internal} @tab yes @tab yes @tab yes +@item @b{thread pool} @tab yes @tab yes @tab yes +@item @b{thread-per-connection} @tab yes @tab yes @tab no +@end multitable +@caption{Supported combinations of event styles and thread modes.} +@end float + + +@section Compiling GNU libmicrohttpd +@cindex compilation +@cindex embedded systems +@cindex portability + +MHD uses the standard GNU system where the usual build process +involves running +@verbatim +$ ./configure +$ make +$ make install +@end verbatim + +MHD supports various options to be given to configure to tailor the +binary to a specific situation. Note that some of these options will +remove portions of the MHD code that are required for +binary-compatibility.

Standard distributions including MHD are expected to +always ship with all features enabled, otherwise unexpected +incompatibilities can arise! + +Here is a list of MHD-specific options that can be given to configure +(canonical configure options such as ``--prefix'' are also supported, for a +full list of options run ``./configure --help''): + +@table @code +@item ``--disable-curl'' +disable running testcases using libcurl + +@item ``--disable-largefile'' +disable support for 64-bit files + +@item ``--disable-messages'' +disable logging of error messages (smaller binary size, not so much fun for debugging) + +@item ``--disable-https'' +disable HTTPS support, even if GNUtls is found; this option must be used if eCOS license is desired as an option (in all cases the resulting binary falls under a GNU LGPL-only license) + +@item ``--disable-postprocessor'' +do not include the post processor API (results in binary incompatibility) + +@item ``--disable-dauth'' +do not include the authentication APIs (results in binary incompatibility) + +@item ``--disable-httpupgrade'' +do not build code for HTTP ``Upgrade'' (smaller binary size, binary incompatible library) + +@item ``--disable-epoll'' +do not include epoll support, even if it supported (minimally smaller binary size, good for portability testing) + +@item ``--enable-coverage'' +set flags for analysis of code-coverage with gcc/gcov (results in slow, large binaries) + +@item ``--with-gcrypt=PATH'' +specifies path to libgcrypt installation + +@item ``--with-gnutls=PATH'' +specifies path to libgnutls installation + + +@end table + +@section Validity of pointers + +MHD will give applications access to its internal data structures +via pointers via arguments and return values from its API. This +creates the question as to how long those pointers are assured to +stay valid. + +Most MHD data structures are associated with the connection of an +HTTP client. Thus, pointers associated with a connection are +typically valid until the connection is finished, at which point +MHD will call the @code{MHD_RequestCompletedCallback} if one is +registered. Applications that have such a callback registered +may assume that keys and values from the +@code{MHD_KeyValueIterator}, return values from +@code{MHD_lookup_connection_value} and the @code{url}, +@code{method} and @code{version} arguments to the +@code{MHD_AccessHandlerCallback} will remain valid until the +respective @code{MHD_RequestCompletedCallback} is invoked. + +In contrast, the @code{upload_data} argument of +@code{MHD_RequestCompletedCallback} as well as all pointers +from the @code{MHD_PostDataIterator} are only valid for the +duration of the callback. + +Pointers returned from @code{MHD_get_response_header} are +valid as long as the response itself is valid. + + +@section Including the microhttpd.h header +@cindex portability +@cindex microhttpd.h + +Ideally, before including "microhttpd.h" you should add the necessary +includes to define the @code{uint64_t}, @code{size_t}, @code{fd_set}, +@code{socklen_t} and @code{struct sockaddr} data types. Which +specific headers are needed may depend on your platform and your build +system might include some tests to provide you with the necessary +conditional operations. For possible suggestions consult +@code{platform.h} and @code{configure.ac} in the MHD distribution. + +Once you have ensured that you manually (!) included the right headers +for your platform before "microhttpd.h", you should also add a line +with @code{#define MHD_PLATFORM_H} which will prevent the +"microhttpd.h" header from trying (and, depending on your platform, +failing) to include the right headers. + +If you do not define MHD_PLATFORM_H, the "microhttpd.h" header will +automatically include headers needed on GNU/Linux systems (possibly +causing problems when porting to other platforms). + +@section SIGPIPE +@cindex signals +MHD does not install a signal handler for SIGPIPE. On platforms where +this is possible (such as GNU/Linux), it disables SIGPIPE for its I/O +operations (by passing MSG_NOSIGNAL or similar). On other platforms, +SIGPIPE signals may be generated from network operations by MHD and +will cause the process to die unless the developer explicitly installs +a signal handler for SIGPIPE. + +Hence portable code using MHD must install a SIGPIPE handler or +explicitly block the SIGPIPE signal. MHD does not do so in order to +avoid messing with other parts of the application that may need to +handle SIGPIPE in a particular way. You can make your application +handle SIGPIPE by calling the following function in @code{main}: + +@verbatim +static void +catcher (int sig) +{ +} + +static void +ignore_sigpipe () +{ + struct sigaction oldsig; + struct sigaction sig; + + sig.sa_handler = &catcher; + sigemptyset (&sig.sa_mask); +#ifdef SA_INTERRUPT + sig.sa_flags = SA_INTERRUPT; /* SunOS */ +#else + sig.sa_flags = SA_RESTART; +#endif + if (0 != sigaction (SIGPIPE, &sig, &oldsig)) + fprintf (stderr, + "Failed to install SIGPIPE handler: %s\n", strerror (errno)); +} +@end verbatim + +@section MHD_UNSIGNED_LONG_LONG +@cindex long long +@cindex MHD_LONG_LONG +@cindex IAR +@cindex ARM +@cindex cortex m3 +@cindex embedded systems + +Some platforms do not support @code{long long}. Hence MHD defines a +macro @code{MHD_UNSIGNED LONG_LONG} which will default to +@code{unsigned long long}. For standard desktop operating systems, +this is all you need to know. + +However, if your platform does not support @code{unsigned long long}, +you should change "platform.h" to define @code{MHD_LONG_LONG} and +@code{MHD_UNSIGNED_LONG_LONG} to an appropriate alternative type and +also define @code{MHD_LONG_LONG_PRINTF} and +@code{MHD_UNSIGNED_LONG_LONG_PRINTF} to the corresponding format +string for printing such a data type. Note that the ``signed'' +versions are deprecated. Also, for historical reasons, +@code{MHD_LONG_LONG_PRINTF} is without the percent sign, whereas +@code{MHD_UNSIGNED_LONG_LONG_PRINTF} is with the percent sign. Newly +written code should only use the unsigned versions. However, you need +to define both in "platform.h" if you need to change the definition +for the specific platform. + + +@section Portability to W32 + +libmicrohttpd in general ported well to W32. Most libmicrohttpd features +are supported. W32 do not support some functions, like epoll and +corresponding MHD features are not available on W32. + + +@section Portability to z/OS + +To compile MHD on z/OS, extract the archive and run + +@verbatim +iconv -f UTF-8 -t IBM-1047 contrib/ascebc > /tmp/ascebc.sh +chmod +x /tmp/ascebc.sh +for n in `find * -type f` +do + /tmp/ascebc.sh $n +done +@end verbatim +to convert all source files to EBCDIC.

Note that this will mean +that IPv4 addresses are returned by MHD in the IPv6-mapped format +(the 'struct sockaddr_in6' format will be used for IPv4 and IPv6). + +@item MHD_USE_PEDANTIC_CHECKS +@cindex deprecated +Deprecated (use @code{MHD_OPTION_STRICT_FOR_CLIENT}). +Be pedantic about the protocol. +Specifically, at the moment, this flag causes MHD to reject HTTP +1.1 connections without a @code{Host} header. This is required by the +standard, but of course in violation of the ``be as liberal as possible +in what you accept'' norm. It is recommended to turn this @strong{ON} +if you are testing clients against MHD, and @strong{OFF} in +production. + +@item MHD_USE_POLL +@cindex FD_SETSIZE +@cindex poll +@cindex select +Use @code{poll()} instead of @code{select()}. This allows sockets with +descriptors @code{>= FD_SETSIZE}. This option currently only works in +conjunction with @code{MHD_USE_INTERNAL_POLLING_THREAD} (at this point). +If you specify @code{MHD_USE_POLL} and the local platform does not +support it, @code{MHD_start_daemon} will return NULL. + +@item MHD_USE_EPOLL +@cindex FD_SETSIZE +@cindex epoll +@cindex select +Use @code{epoll()} instead of @code{poll()} or @code{select()}. This +allows sockets with descriptors @code{>= FD_SETSIZE}. This option is +only available on some systems and does not work in conjunction with +@code{MHD_USE_THREAD_PER_CONNECTION} (at this point). If you specify +@code{MHD_USE_EPOLL} and the local platform does not support it, +@code{MHD_start_daemon} will return NULL. Using @code{epoll()} +instead of @code{select()} or @code{poll()} can in some situations +result in significantly higher performance as the system call has +fundamentally lower complexity (O(1) for @code{epoll()} vs. O(n) for +@code{select()}/@code{poll()} where n is the number of open +connections). + +@item MHD_USE_TURBO +@cindex performance +Enable optimizations to aggressively improve performance. + +Currently, the optimizations this option enables are based on +opportunistic reads and writes. Bascially, MHD will simply try to +read or write or accept on a socket before checking that the socket is +ready for IO using the event loop mechanism. As the sockets are +non-blocking, this may fail (at a loss of performance), but generally +MHD does this in situations where the operation is likely to succeed, +in which case performance is improved. Setting the flag should generally +be safe (even though the code is slightly more experimental). You may +want to benchmark your application to see if this makes any difference +for you. + + +@item MHD_USE_SUPPRESS_DATE_NO_CLOCK +@cindex date +@cindex clock +@cindex embedded systems +Suppress (automatically) adding the 'Date:' header to HTTP responses. +This option should ONLY be used on systems that do not have a clock +and that DO provide other mechanisms for cache control. See also +RFC 2616, section 14.18 (exception 3). + + +@item MHD_USE_NO_LISTEN_SOCKET +@cindex listen +@cindex proxy +@cindex embedded systems +Run the HTTP server without any listen socket. This option only makes +sense if @code{MHD_add_connection} is going to be used exclusively to +connect HTTP clients to the HTTP server. This option is incompatible +with using a thread pool; if it is used, +@code{MHD_OPTION_THREAD_POOL_SIZE} is ignored. + + +@item MHD_USE_ITC +@cindex quiesce +Force MHD to use a signal inter-thread communication channel to notify +the event loop (of threads) of our shutdown and other events. This is +required if an application uses @code{MHD_USE_INTERNAL_POLLING_THREAD} +and then performs @code{MHD_quiesce_daemon} (which eliminates our +ability to signal termination via the listen socket). In these modes, +@code{MHD_quiesce_daemon} will fail if this option was not set. Also, +use of this option is automatic (as in, you do not even have to +specify it), if @code{MHD_USE_NO_LISTEN_SOCKET} is specified. In +"external" select mode, this option is always simply ignored. + +Using this option also guarantees that MHD will not call +@code{shutdown()} on the listen socket, which means a parent +process can continue to use the socket. + +@item MHD_ALLOW_SUSPEND_RESUME +Enables using @code{MHD_suspend_connection} and +@code{MHD_resume_connection}, as performing these calls requires some +additional inter-thred communication channels to be created, and code +not using these calls should not pay the cost. + +@item MHD_USE_TCP_FASTOPEN +@cindex listen +Enable TCP_FASTOPEN on the listen socket. TCP_FASTOPEN is currently +supported on Linux >= 3.6. On other systems using this option with +cause @code{MHD_start_daemon} to fail. + + +@item MHD_ALLOW_UPGRADE +@cindex upgrade +This option must be set if you want to upgrade connections +(via ``101 Switching Protocols'' responses). This requires MHD to +allocate additional resources, and hence we require this +special flag so we only use the resources that are really needed. + + +@item MHD_USE_AUTO +Automatically select best event loop style (polling function) +depending on requested mode by other MHD flags and functions available +on platform. If application doesn't have requirements for any +specific polling function, it's recommended to use this flag. This +flag is very convenient for multiplatform applications. + +@end table +@end deftp + + +@deftp {Enumeration} MHD_OPTION +MHD options. Passed in the varargs portion of +@code{MHD_start_daemon()}. + +@table @code +@item MHD_OPTION_END +No more options / last option. This is used to terminate the VARARGs +list. + +@item MHD_OPTION_CONNECTION_MEMORY_LIMIT +@cindex memory, limiting memory utilization +Maximum memory size per connection (followed by a @code{size_t}). The +default is 32 kB (32*1024 bytes) as defined by the internal constant +@code{MHD_POOL_SIZE_DEFAULT}. Values above 128k are unlikely to +result in much benefit, as half of the memory will be typically used +for IO, and TCP buffers are unlikely to support window sizes above 64k +on most systems. + +@item MHD_OPTION_CONNECTION_MEMORY_INCREMENT +@cindex memory +Increment to use for growing the read buffer (followed by a +@code{size_t}). The default is 1024 (bytes). Increasing this value +will make MHD use memory for reading more aggressively, which can +reduce the number of @code{recvfrom} calls but may increase the number +of @code{sendto} calls. The given value must fit within +MHD_OPTION_CONNECTION_MEMORY_LIMIT. + +@item MHD_OPTION_CONNECTION_LIMIT +@cindex connection, limiting number of connections +Maximum number of concurrent connections to accept (followed by an +@code{unsigned int}). The default is @code{FD_SETSIZE - 4} (the +maximum number of file descriptors supported by @code{select} minus +four for @code{stdin}, @code{stdout}, @code{stderr} and the server +socket). In other words, the default is as large as possible. + +If the connection limit is reached, MHD's behavior depends a bit on +other options. If @code{MHD_USE_ITC} was given, MHD +will stop accepting connections on the listen socket. This will cause +the operating system to queue connections (up to the @code{listen()} +limit) above the connection limit. Those connections will be held +until MHD is done processing at least one of the active connections. +If @code{MHD_USE_ITC} is not set, then MHD will continue +to @code{accept()} and immediately @code{close()} these connections. + +Note that if you set a low connection limit, you can easily get into +trouble with browsers doing request pipelining. For example, if your +connection limit is ``1'', a browser may open a first connection to +access your ``index.html'' file, keep it open but use a second +connection to retrieve CSS files, images and the like. In fact, modern +browsers are typically by default configured for up to 15 parallel +connections to a single server. If this happens, MHD will refuse to +even accept the second connection until the first connection is +closed --- which does not happen until timeout. As a result, the +browser will fail to render the page and seem to hang. If you expect +your server to operate close to the connection limit, you should +first consider using a lower timeout value and also possibly add +a ``Connection: close'' header to your response to ensure that +request pipelining is not used and connections are closed immediately +after the request has completed: +@example +MHD_add_response_header (response, + MHD_HTTP_HEADER_CONNECTION, + "close"); +@end example + +@item MHD_OPTION_CONNECTION_TIMEOUT +@cindex timeout +After how many seconds of inactivity should a connection automatically +be timed out? (followed by an @code{unsigned int}; use zero for no +timeout). The default is zero (no timeout). + +@item MHD_OPTION_NOTIFY_COMPLETED +Register a function that should be called whenever a request has been +completed (this can be used for application-specific clean up). +Requests that have never been presented to the application (via +@code{MHD_AccessHandlerCallback()}) will not result in +notifications. + +This option should be followed by @strong{TWO} pointers. First a +pointer to a function of type @code{MHD_RequestCompletedCallback()} +and second a pointer to a closure to pass to the request completed +callback. The second pointer maybe @code{NULL}. + +@item MHD_OPTION_NOTIFY_CONNECTION +Register a function that should be called when the TCP connection to a +client is opened or closed. Note that +@code{MHD_OPTION_NOTIFY_COMPLETED} and the @code{con_cls} argument to +the @code{MHD_AccessHandlerCallback} are per HTTP request (and there +can be multiple HTTP requests per TCP connection). The registered +callback is called twice per TCP connection, with +@code{MHD_CONNECTION_NOTIFY_STARTED} and +@code{MHD_CONNECTION_NOTIFY_CLOSED} respectively. An additional +argument can be used to store TCP connection specific information, +which can be retrieved using @code{MHD_CONNECTION_INFO_SOCKET_CONTEXT} +during the lifetime of the TCP connection. The respective location is +not the same as the HTTP-request-specific @code{con_cls} from the +@code{MHD_AccessHandlerCallback}. + +This option should be followed by @strong{TWO} pointers. First a +pointer to a function of type @code{MHD_NotifyConnectionCallback()} +and second a pointer to a closure to pass to the request completed +callback. The second pointer maybe @code{NULL}. + +@item MHD_OPTION_PER_IP_CONNECTION_LIMIT +Limit on the number of (concurrent) connections made to the +server from the same IP address. Can be used to prevent one +IP from taking over all of the allowed connections. If the +same IP tries to establish more than the specified number of +connections, they will be immediately rejected. The option +should be followed by an @code{unsigned int}. The default is +zero, which means no limit on the number of connections +from the same IP address. + +@item MHD_OPTION_LISTEN_BACKLOG_SIZE +Set the size of the @code{listen()} back log queue of the TCP socket. +Takes an @code{unsigned int} as the argument. Default is the +platform-specific value of @code{SOMAXCONN}. + +@item MHD_OPTION_STRICT_FOR_CLIENT +Specify how strict we should enforce the HTTP protocol. +Takes an @code{int} as the argument. Default is zero. + +If set to 1, MHD will be strict about the protocol. Specifically, at +the moment, this flag uses MHD to reject HTTP 1.1 connections without +a "Host" header. This is required by the standard, but of course in +violation of the "be as liberal as possible in what you accept" norm. +It is recommended to set this to 1 if you are testing clients against +MHD, and 0 in production. + +If set to -1 MHD will be permissive about the protocol, allowing +slight deviations that are technically not allowed by the +RFC. Specifically, at the moment, this flag causes MHD to allow spaces +in header field names. This is disallowed by the standard. + +It is not recommended to set it to -1 on publicly available servers as +it may potentially lower level of protection. + + +@item MHD_OPTION_SOCK_ADDR +@cindex bind, restricting bind +Bind daemon to the supplied socket address. This option should be followed by a +@code{struct sockaddr *}. If @code{MHD_USE_IPv6} is specified, +the @code{struct sockaddr*} should point to a @code{struct sockaddr_in6}, +otherwise to a @code{struct sockaddr_in}. If this option is not specified, +the daemon will listen to incoming connections from anywhere. If you use this +option, the 'port' argument from @code{MHD_start_daemon} is ignored and the port +from the given @code{struct sockaddr *} will be used instead. + +@item MHD_OPTION_URI_LOG_CALLBACK +@cindex debugging +@cindex logging +@cindex query string +Specify a function that should be called before parsing the URI from +the client. The specified callback function can be used for processing +the URI (including the options) before it is parsed. The URI after +parsing will no longer contain the options, which maybe inconvenient for +logging. This option should be followed by two arguments, the first +one must be of the form +@example + void * my_logger(void * cls, const char * uri, struct MHD_Connection *con) +@end example +where the return value will be passed as +@code{*con_cls} in calls to the @code{MHD_AccessHandlerCallback} +when this request is processed later; returning a +value of @code{NULL} has no special significance; (however, +note that if you return non-@code{NULL}, you can no longer +rely on the first call to the access handler having +@code{NULL == *con_cls} on entry) +@code{cls} will be set to the second argument following +MHD_OPTION_URI_LOG_CALLBACK. Finally, @code{uri} will +be the 0-terminated URI of the request. + +Note that during the time of this call, most of the connection's state +is not initialized (as we have not yet parsed he headers). However, +information about the connecting client (IP, socket) is available. + +@item MHD_OPTION_HTTPS_MEM_KEY +@cindex SSL +@cindex TLS +Memory pointer to the private key to be used by the +HTTPS daemon. This option should be followed by an +"const char*" argument. +This should be used in conjunction with 'MHD_OPTION_HTTPS_MEM_CERT'. + +@item MHD_OPTION_HTTPS_KEY_PASSWORD +@cindex SSL +@cindex TLS +Memory pointer to the password that decrypts the +private key to be used by the HTTPS daemon. +This option should be followed by an +"const char*" argument. +This should be used in conjunction with 'MHD_OPTION_HTTPS_MEM_KEY'. + +The password (or passphrase) is only used immediately during +@code{MHD_start_daemon()}. Thus, the application may want to +erase it from memory afterwards for additional security. + +@item MHD_OPTION_HTTPS_MEM_CERT +@cindex SSL +@cindex TLS +Memory pointer to the certificate to be used by the +HTTPS daemon. This option should be followed by an +"const char*" argument. +This should be used in conjunction with 'MHD_OPTION_HTTPS_MEM_KEY'. + +@item MHD_OPTION_HTTPS_MEM_TRUST +@cindex SSL +@cindex TLS +Memory pointer to the CA certificate to be used by the +HTTPS daemon to authenticate and trust clients certificates. +This option should be followed by an "const char*" argument. +The presence of this option activates the request of certificate +to the client. The request to the client is marked optional, and +it is the responsibility of the server to check the presence +of the certificate if needed. +Note that most browsers will only present a client certificate +only if they have one matching the specified CA, not sending +any certificate otherwise. + +@item MHD_OPTION_HTTPS_CRED_TYPE +@cindex SSL +@cindex TLS +Daemon credentials type.

The string is passed +unchanged to gnutls_priority_init. If this option is not +specified, ``NORMAL'' is used. + +@item MHD_OPTION_HTTPS_CERT_CALLBACK +@cindex SSL +@cindex TLS +@cindex SNI +Use a callback to determine which X.509 certificate should be used for +a given HTTPS connection. This option should be followed by a +argument of type "gnutls_certificate_retrieve_function2 *". This +option provides an alternative to MHD_OPTION_HTTPS_MEM_KEY and +MHD_OPTION_HTTPS_MEM_CERT. You must use this version if multiple +domains are to be hosted at the same IP address using TLS's Server +Name Indication (SNI) extension. In this case, the callback is +expected to select the correct certificate based on the SNI +information provided. The callback is expected to access the SNI data +using gnutls_server_name_get(). Using this option requires GnuTLS 3.0 +or higher. + +@item MHD_OPTION_DIGEST_AUTH_RANDOM +@cindex digest auth +@cindex random +Digest Authentication nonce's seed. + +This option should be followed by two arguments. First an integer of +type "size_t" which specifies the size of the buffer pointed to by the +second argument in bytes. Note that the application must ensure that +the buffer of the second argument remains allocated and unmodified +while the daemon is running. For security, you SHOULD provide a fresh +random nonce when using MHD with Digest Authentication. + +@item MHD_OPTION_NONCE_NC_SIZE +@cindex digest auth +@cindex replay attack + +Size of an array of nonce and nonce counter map. This option must be +followed by an "unsigned int" argument that have the size (number of +elements) of a map of a nonce and a nonce-counter. If this option +is not specified, a default value of 4 will be used (which might be +too small for servers handling many requests). If you do not use +digest authentication at all, you can specify a value of zero to +save some memory. + +You should calculate the value of NC_SIZE based on the number of +connections per second multiplied by your expected session duration +plus a factor of about two for hash table collisions. For example, if +you expect 100 digest-authenticated connections per second and the +average user to stay on your site for 5 minutes, then you likely need +a value of about 60000. On the other hand, if you can only expect +only 10 digest-authenticated connections per second, tolerate browsers +getting a fresh nonce for each request and expect a HTTP request +latency of 250 ms, then a value of about 5 should be fine. + + +@item MHD_OPTION_LISTEN_SOCKET +@cindex systemd +Listen socket to use. Pass a listen socket for MHD to use +(systemd-style). If this option is used, MHD will not open its own +listen socket(s). The argument passed must be of type "int" and refer +to an existing socket that has been bound to a port and is listening. + +@item MHD_OPTION_EXTERNAL_LOGGER +@cindex logging +Use the given function for logging error messages. +This option must be followed by two arguments; the +first must be a pointer to a function +of type 'void fun(void * arg, const char * fmt, va_list ap)' +and the second a pointer of type 'void*' which will +be passed as the "arg" argument to "fun". + +Note that MHD will not generate any log messages without +the MHD_USE_ERROR_LOG flag set and if MHD was compiled +with the "--disable-messages" flag. + +@item MHD_OPTION_THREAD_POOL_SIZE +@cindex performance +Number (unsigned int) of threads in thread pool. Enable +thread pooling by setting this value to to something +greater than 1. Currently, thread model must be +MHD_USE_INTERNAL_POLLING_THREAD if thread pooling is enabled +(@code{MHD_start_daemon} returns @code{NULL} for an unsupported thread +model). + +@item MHD_OPTION_ARRAY +@cindex options +@cindex foreign-function interface +This option can be used for initializing MHD using options from an +array. A common use for this is writing an FFI for MHD. The actual +options given are in an array of 'struct MHD_OptionItem', so this +option requires a single argument of type 'struct MHD_OptionItem'. +The array must be terminated with an entry @code{MHD_OPTION_END}. + +An example for code using MHD_OPTION_ARRAY is: +@example +struct MHD_OptionItem ops[] = @{ + @{ MHD_OPTION_CONNECTION_LIMIT, 100, NULL @}, + @{ MHD_OPTION_CONNECTION_TIMEOUT, 10, NULL @}, + @{ MHD_OPTION_END, 0, NULL @} +@}; +d = MHD_start_daemon(0, 8080, NULL, NULL, dh, NULL, + MHD_OPTION_ARRAY, ops, + MHD_OPTION_END); +@end example +For options that expect a single pointer argument, the +second member of the @code{struct MHD_OptionItem} is ignored. +For options that expect two pointer arguments, the first +argument must be cast to @code{intptr_t}. + +@item MHD_OPTION_UNESCAPE_CALLBACK +@cindex internationalization +@cindex escaping + +Specify a function that should be called for unescaping escape +sequences in URIs and URI arguments. Note that this function will NOT +be used by the MHD_PostProcessor. If this option is not specified, +the default method will be used which decodes escape sequences of the +form "%HH". This option should be followed by two arguments, the +first one must be of the form + +@example + size_t my_unescaper(void * cls, struct MHD_Connection *c, char *s) +@end example + +where the return value must be @code{strlen(s)} and @code{s} should be +updated. Note that the unescape function must not lengthen @code{s} +(the result must be shorter than the input and still be 0-terminated). +@code{cls} will be set to the second argument following +MHD_OPTION_UNESCAPE_CALLBACK. + + +@item MHD_OPTION_THREAD_STACK_SIZE +@cindex stack +@cindex thread +@cindex pthread +@cindex embedded systems +Maximum stack size for threads created by MHD. This option must be +followed by a @code{size_t}). Not specifying this option or using +a value of zero means using the system default (which is likely to +differ based on your platform). + +@item MHD_OPTION_TCP_FASTQUEUE_QUEUE_SIZE +@cindex listen +When the flag @code{MHD_USE_TCP_FASTOPEN} is used, this option sets the +connection handshake queue size for the TCP FASTOPEN connections. Note +that a TCP FASTOPEN connection handshake occupies more resources than a +TCP handshake as the SYN packets also contain DATA which is kept in the +associate state until handshake is completed. If this option is not +given the queue size is set to a default value of 10. This option must +be followed by a @code{unsigned int}. + +@item MHD_OPTION_HTTPS_MEM_DHPARAMS +@cindex TLS +@cindex SSL +@cindex DH +Memory pointer for the Diffie-Hellman parameters (dh.pem) to be used +by the HTTPS daemon for key exchange. This option must be followed by +a @code{const char *} argument. The argument would be a zero-terminated +string with a PEM encoded PKCS3 DH parameters structure suitable +for passing to @code{gnutls_dh_parms_import_pkcs3}. + +@item MHD_OPTION_LISTENING_ADDRESS_REUSE +@cindex bind, restricting bind +@cindex reusing listening address +This option must be followed by a @code{unsigned int} argument. +If this option is present and true (nonzero) parameter is given, allow reusing +the address:port of the listening socket (using @code{SO_REUSEPORT} on most +platforms, and @code{SO_REUSEADDR} on Windows). If a false (zero) parameter is +given, disallow reusing the the address:port of the listening socket (this +usually requires no special action, but @code{SO_EXCLUSIVEADDRUSE} is needed on +Windows). If this option is not present @code{SO_REUSEADDR} is used on all +platforms except Windows so reusing of address:port is disallowed. + +@end table +@end deftp + + +@deftp {C Struct} MHD_OptionItem +Entry in an MHD_OPTION_ARRAY.

The Free Translation Project is a +way to get maintainers of free software, translators, and users all +together, so that free software will gradually become able to speak many +languages. A few packages already provide translations for their +messages. + + If you found this 'ABOUT-NLS' file inside a distribution, you may +assume that the distributed package does use GNU 'gettext' internally, +itself available at your nearest GNU archive site. But you do _not_ +need to install GNU 'gettext' prior to configuring, installing or using +this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work on translations can contact the appropriate team. + +1.1 INSTALL Matters +=================== + +Some packages are "localizable" when properly installed; the programs +they contain can be made to speak your own native language. Most such +packages use GNU 'gettext'. Other packages have their own ways to +internationalization, predating GNU 'gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system already +provides the GNU 'gettext' functions. Installers may use special +options at configuration time for changing the default behaviour. The +command: + + ./configure --disable-nls + +will _totally_ disable translation of messages. + + When you already have GNU 'gettext' installed on your system and run +configure without an option for your new package, 'configure' will +probably detect the previously built and installed 'libintl' library and +will decide to use it. If not, you may have to to use the +'--with-libintl-prefix' option to tell 'configure' where to look for it. + + Internationalized packages usually have many 'po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at 'configure' time by using the +'--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable 'LINGUAS' +may be set, prior to configuration, to limit the installed set. +'LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +1.2 Using This Package +====================== + +As a user, if your language has been installed for this package, you +only have to set the 'LANG' environment variable to the appropriate +'LL_CC' combination. If you happen to have the 'LC_ALL' or some other +'LC_xxx' environment variables set, you should unset them before setting +'LANG', otherwise the setting of 'LANG' will not have the desired +effect. Here 'LL' is an ISO 639 two-letter language code, and 'CC' is +an ISO 3166 two-letter country code. For example, let's suppose that +you speak German and live in Germany. At the shell prompt, merely +execute 'setenv LANG de_DE' (in 'csh'), 'export LANG; LANG=de_DE' (in +'sh') or 'export LANG=de_DE' (in 'bash'). This can be done from your +'.login' or '.profile' file, once and for all. + + You might think that the country code specification is redundant. +But in fact, some languages have dialects in different countries. For +example, 'de_AT' is used for Austria, and 'pt_BR' for Brazil. The +country code serves to distinguish the dialects. + + The locale naming convention of 'LL_CC', with 'LL' denoting the +language and 'CC' denoting the country, is the one use on systems based +on GNU libc. On other systems, some variations of this scheme are used, +such as 'LL' or 'LL_CC.ENCODING'. You can get the list of locales +supported by your system for your language by running the command +'locale -a | grep '^LL''. + + Not all programs have translations for all languages. By default, an +English message is shown in place of a nonexistent translation. If you +understand other languages, you can set up a priority list of languages. +This is done through a different environment variable, called +'LANGUAGE'. GNU 'gettext' gives preference to 'LANGUAGE' over 'LANG' +for the purpose of message handling, but you still need to have 'LANG' +set to the primary language; this is required by other parts of the +system libraries. For example, some Swedish users who would rather read +translations in German than English for when Swedish is not available, +set 'LANGUAGE' to 'sv:de' while leaving 'LANG' to 'sv_SE'. + + Special advice for Norwegian users: The language code for Norwegian +bokma*l changed from 'no' to 'nb' recently (in 2003). During the +transition period, while some message catalogs for this language are +installed under 'nb' and some older ones under 'no', it's recommended +for Norwegian users to set 'LANGUAGE' to 'nb:no' so that both newer and +older translations are used. + + In the 'LANGUAGE' environment variable, but not in the 'LANG' +environment variable, 'LL_CC' combinations can be abbreviated as 'LL' to +denote the language's main dialect. For example, 'de' is equivalent to +'de_DE' (German as spoken in Germany), and 'pt' to 'pt_PT' (Portuguese +as spoken in Portugal) in this context. + +1.3 Translating Teams +===================== + +For the Free Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list. The up-to-date list of +teams can be found at the Free Translation Project's homepage, +'http://translationproject.org/', in the "Teams" area. + + If you'd like to volunteer to _work_ at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is _not_ the same as the list itself, it has +'-request' appended. For example, speakers of Swedish can send a +message to 'sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate _actively_ +in translations, or at solving translational difficulties, rather than +merely lurking around. If your team does not exist yet and you want to +start one, or if you are unsure about what to do or how to get started, +please write to 'coordinator@translationproject.org' to reach the +coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology in use. Proven linguistic skills are praised more than +programming skills, here. + +1.4 Available Packages +====================== + +Languages are not equally supported in all packages. The following +matrix shows the current state of internationalization, as of Jun 2014. +The matrix shows, in regard of each package, for which languages PO +files have been submitted to translation

matrix are higher than the number of +visible blocks let us expect. This is because a few extra PO files are +used for implementing regional variants of languages, or language +dialects. + + For a PO file in the matrix above to be effective, the package to +which it applies should also have been internationalized and distributed +as such by its maintainer. There might be an observable lag between the +mere existence a PO file and its wide availability in a distribution. + + If Jun 2014 seems to be old, you may fetch a more recent copy of this +'ABOUT-NLS' file on most GNU archive sites. The most up-to-date matrix +with full percentage details can be found at +'http://translationproject.org/extra/matrix.html'. + +1.5 Using 'gettext' in new packages +=================================== + +If you are writing a freely available program and want to +internationalize it you are welcome to use GNU 'gettext' in your +package. Of course you have to respect the GNU Lesser General Public +License which covers the use of the GNU 'gettext' library. This means +in particular that even non-free programs can use 'libintl' as a shared +library, whereas only free software can use 'libintl' as a static +library or use modified versions of 'libintl'. + + Once the sources are changed appropriately and the setup can handle +the use of 'gettext' the only thing missing are the translations. The +Free Translation Project is also available for packages which are not +developed inside the GNU project. Therefore the information given above +applies also for every other Free Software Project. Contact +'coordinator@translationproject.org' to make the '.pot' files available +to the translation teams. diff --git a/po/ChangeLog b/po/ChangeLog new file mode 100644 index 0000000..47e3fc0 --- /dev/null +++ b/po/ChangeLog @@ -0,0 +1,5 @@ +2016-09-05 gettextize + + * Makefile.in.in: Upgrade to gettext-0.19.8.1. + * Rules-quot: Upgrade to gettext-0.19.8.1. + diff --git a/po/Makefile.in.in b/po/Makefile.in.in new file mode 100644 index 0000000..4e5c700 --- /dev/null +++ b/po/Makefile.in.in @@ -0,0 +1,516 @@ +# Makefile for PO directory in any package using GNU gettext. +# Copyright (C) 1995-1997, 2000-2007, 2009-2010 by Ulrich Drepper +# +# Copying and distribution of this file, with or without modification, +# are permitted in any medium without royalty provided the copyright +# notice and this notice are preserved.
