/** \ingroup python
* \name Class: Rpmts
* \class Rpmts
* \brief A python rpm.ts object represents an RPM transaction set.
*
* The transaction set is the workhorse of RPM. It performs the
* installation and upgrade of packages. The rpm.ts object is
* instantiated by the TransactionSet function in the rpm module.
*
* The TransactionSet function takes two optional arguments. The first
* argument is the root path. The second is the verify signature disable flags,
* a set of the following bits:
*
* - rpm.RPMVSF_NOHDRCHK if set, don't check rpmdb headers
* - rpm.RPMVSF_NEEDPAYLOAD if not set, check header+payload (if possible)
* - rpm.RPMVSF_NOSHA1HEADER if set, don't check header SHA1 digest
* - rpm.RPMVSF_NODSAHEADER if set, don't check header DSA signature
* - rpm.RPMVSF_NOMD5 if set, don't check header+payload MD5 digest
* - rpm.RPMVSF_NODSA if set, don't check header+payload DSA signature
* - rpm.RPMVSF_NORSA if set, don't check header+payload RSA signature
*
* For convenience, there are the following masks:
* - rpm.RPMVSF_MASK_NODIGESTS if set, don't check digest(s).
* - rpm.RPMVSF_MASK_NOSIGNATURES if set, don't check signature(s).
*
* A rpm.ts object has the following methods:
*
* - addInstall(hdr,data,mode) Add an install element to a transaction set.
* @param hdr the header to be added
* @param data user data that will be passed to the transaction callback
* during transaction execution
* @param mode optional argument that specifies if this package should
* be installed ('i'), upgraded ('u').
*
* - addErase(name) Add an erase element to a transaction set.
* @param name the package name to be erased
*
* - check() Perform a dependency check on the transaction set. After
* headers have been added to a transaction set, a dependency
* check can be performed to make sure that all package
* dependencies are satisfied.
* @return None If there are no unresolved dependencies
* Otherwise a list of complex tuples is returned, one tuple per
* unresolved dependency, with
* The format of the dependency tuple is:
* ((packageName, packageVersion, packageRelease),
* (reqName, reqVersion),
* needsFlags,
* suggestedPackage,
* sense)
* packageName, packageVersion, packageRelease are the name,
* version, and release of the package that has the unresolved
* dependency or conflict.
* The reqName and reqVersion are the name and version of the
* requirement or conflict.
* The needsFlags is a bitfield that describes the versioned
* nature of a requirement or conflict. The constants
* rpm.RPMSENSE_LESS, rpm.RPMSENSE_GREATER, and
* rpm.RPMSENSE_EQUAL can be logical ANDed with the needsFlags
* to get versioned dependency information.
* suggestedPackage is a tuple if the dependency check was aware
* of a package that solves this dependency problem when the
* dependency check was run. Packages that are added to the
* transaction set as "available" are examined during the
* dependency check as possible dependency solvers. The tuple
* contains two values, (header, suggestedName). These are set to
* the header of the suggested package and its name, respectively.
* If there is no known package to solve the dependency problem,
* suggestedPackage is None.
* The constants rpm.RPMDEP_SENSE_CONFLICTS and
* rpm.RPMDEP_SENSE_REQUIRES are set to show a dependency as a
* requirement or a conflict.
*
* - ts.order() Do a topological sort of added element relations.
* @return None
*
* - ts.setFlags(transFlags) Set transaction set flags.
* @param transFlags - bit(s) to control transaction operations. The
* following values can be logically OR'ed together:
* - rpm.RPMTRANS_FLAG_TEST - test mode, do not modify the RPM
* database, change any files, or run any package scripts
* - rpm.RPMTRANS_FLAG_BUILD_PROBS - only build a list of
* problems encountered when attempting to run this transaction
* set
* - rpm.RPMTRANS_FLAG_JUSTDB - only make changes to the rpm
* database, do not modify files.
* - rpm.RPMTRANS_FLAG_NOSCRIPTS - do not execute package scripts
* - rpm.RPMTRANS_FLAG_NOTRIGGERS - do not run trigger scripts
* - rpm.RPMTRANS_FLAG_NO* - disable specific scripts and triggers
* - rpm.RPMTRANS_FLAG_NODOCS - do not install files marked as %doc
* - rpm.RPMTRANS_FLAG_NOPLUGINS - do not run plugins
* - rpm.RPMTRANS_FLAG_NOFILEDIGEST - disable checking checksums
* - rpm.RPMTRANS_FLAG_ALLFILES - create all files, even if a
* file is marked %config(missingok) and an upgrade is
* being performed.
* - rpm.RPMTRANS_FLAG_NOCONFIGS - skip config files
* - rpm.RPMTRANS_FLAG_DEPLOOPS - enable debugging for dependency loops
* @return previous transFlags
*
* - ts.setProbFilter(ignoreSet) Set transaction set problem filter.
* @param problemSetFilter - control bit(s) to ignore classes of problems,
* a logical or of one or more of the following bit(s):
* - rpm.RPMPROB_FILTER_IGNOREOS -
* - rpm.RPMPROB_FILTER_IGNOREARCH -
* - rpm.RPMPROB_FILTER_REPLACEPKG -
* - rpm.RPMPROB_FILTER_FORCERELOCATE -
* - rpm.RPMPROB_FILTER_REPLACENEWFILES -
* - rpm.RPMPROB_FILTER_REPLACEOLDFILES -
* - rpm.RPMPROB_FILTER_OLDPACKAGE -
* - rpm.RPMPROB_FILTER_DISKSPACE -
* @return previous ignoreSet
*
* - ts.run(callback,data) Attempt to execute a transaction set.
* After the transaction set has been populated with install/upgrade or
* erase actions, the transaction set can be executed by invoking
* the ts.run() method.
