| Starting with 2.4.7, libxml2 makes provisions to ensure that concurrent |
|
|
|
|
|
|
Packit Service |
a31ea6 |
threads can safely work in parallel parsing different documents. There is
|
|
Packit Service |
a31ea6 |
however a couple of things to do to ensure it:
|
|
Packit Service |
a31ea6 |
configure the library accordingly using the --with-threads options
|
|
Packit Service |
a31ea6 |
call xmlInitParser() in the "main" thread before using any of the
|
|
Packit Service |
a31ea6 |
libxml2 API (except possibly selecting a different memory allocator)
|
|
Packit Service |
a31ea6 |
Note that the thread safety cannot be ensured for multiple threads sharing
|
|
Packit Service |
a31ea6 |
the same document, the locking must be done at the application level, libxml
|
|
Packit Service |
a31ea6 |
exports a basic mutex and reentrant mutexes API in <libxml/threads.h>.
|
|

The parts of the library checked for thread safety are:
|
|

concurrent loading
|

file access resolution
|

|
|

global variables per-thread override
|
|
Packit Service |

memory handling
|
|
Packit Service |

XPath has been tested for threaded usage on non-modified document
|
|
Packit Service |
a31ea6 |
for example when using libxslt, but make 100% sure the documents
|

are accessed read-only !Daniel Veillard </body></html>
