37 The pool is libsolv\(cqs central resource manager\&. A pool consists of Solvables, Repositories, Dependencies, each indexed by Ids\&.
45 my \fI$pool\fR \fB= solv::Pool\->new()\fR;
46 \fIpool\fR \fB= solv\&.Pool()\fR
47 \fIpool\fR \fB= Solv::Pool\&.new()\fR
53 Create a new pool instance\&. In most cases you just need one pool\&.
60 \fBvoid *appdata;\fR /* read/write */
61 \fI$pool\fR\fB\->{\*(Aqappdata\*(Aq}\fR
62 \fIpool\fR\fB\&.appdata\fR
63 \fIpool\fR\fB\&.appdata\fR
69 Application specific data that may be used in any way by the code using the pool\&.
75 \fBSolvable solvables[];\fR /* read only */
76 my \fI$solvable\fR \fB=\fR \fI$pool\fR\fB\->{\*(Aqsolvables\*(Aq}\->[\fR\fI$solvid\fR\fB]\fR;
77 \fIsolvable\fR \fB=\fR \fIpool\fR\fB\&.solvables[\fR\fIsolvid\fR\fB]\fR
78 \fIsolvable\fR \fB=\fR \fIpool\fR\fB\&.solvables[\fR\fIsolvid\fR\fB]\fR
84 Look up a Solvable by its id\&.
90 \fBRepo repos[];\fR /* read only */
91 my \fI$repo\fR \fB=\fR \fI$pool\fR\fB\->{\*(Aqrepos\*(Aq}\->[\fR\fI$repoid\fR\fB]\fR;
92 \fIrepo\fR \fB=\fR \fIpool\fR\fB\&.repos[\fR\fIrepoid\fR\fB]\fR
93 \fIrepo\fR \fB=\fR \fIpool\fR\fB\&.repos[\fR\fIrepoid\fR\fB]\fR
99 Look up a Repository by its id\&.
105 \fBRepo *installed;\fR /* read/write */
106 \fI$pool\fR\fB\->{\*(Aqinstalled\*(Aq} =\fR \fI$repo\fR;
107 \fIpool\fR\fB\&.installed =\fR \fIrepo\fR
108 \fIpool\fR\fB\&.installed =\fR \fIrepo\fR
114 Define which repository contains all the installed packages\&.
117 \fBPOOL_FLAG_PROMOTEEPOCH\fR
119 Promote the epoch of the providing dependency to the requesting dependency if it does not contain an epoch\&. Used at some time in old rpm versions, modern systems should never need this\&.
122 \fBPOOL_FLAG_FORBIDSELFCONFLICTS\fR
124 Disallow the installation of packages that conflict with themselfs\&. Debian always allowd self\-conflicting packages, rpm used to forbid them but switched to also allowing them recently\&.
127 \fBPOOL_FLAG_OBSOLETEUSESPROVIDES\fR
129 Make obsolete type dependency match against provides instead of just the name and version of packages\&. Very old versions of rpm used the name/version, then it got switched to provides and later switched back again to just name/version\&.
132 \fBPOOL_FLAG_IMPLICITOBSOLETEUSESPROVIDES\fR
134 An implicit obsoletes is the internal mechanism to remove the old package on an update\&. The default is to remove all packages with the same name, rpm\-5 switched to also removing packages providing the same name\&.
137 \fBPOOL_FLAG_OBSOLETEUSESCOLORS\fR
139 Rpm\(cqs multilib implementation (used in RedHat and Fedora) distinguishes between 32bit and 64bit packages (the terminology is that they have a different color)\&. If obsolteusescolors is set, packages with different colors will not obsolete each other\&. This is also true for implicit obsoletes, thus you can install both the 32bit and the 64bit version of a package with the same name\&.
142 \fBPOOL_FLAG_NOINSTALLEDOBSOLETES\fR
144 New versions of rpm consider the obsoletes of installed packages when checking for dependency, thus you may not install a package that is obsoleted by some other installed package, unless you also deinstall the other package\&.
147 \fBPOOL_FLAG_HAVEDISTEPOCH\fR
149 Mandriva added a new field called distepoch that gets checked in version comparison if the epoch/version/release of two packages are the same\&.
152 \fBPOOL_FLAG_NOOBSOLETESMULTIVERSION\fR
154 If a package is installed in multiversionmode, rpm used to ignore both the implicit obsoletes and the obsolete dependency of a package\&. This was changed to ignoring just the implicit obsoletes, thus you may install multiple versions of the same name, but obsoleted packages still get removed\&.
163 \fI$pool\fR\fB\->free()\fR;
164 \fIpool\fR\fB\&.free()\fR
165 \fIpool\fR\fB\&.free()\fR
171 Free a pool\&. This is currently done with a method instead of relying on reference counting or garbage collection because it\(cqs hard to track every reference to a pool\&.
177 \fBvoid setdebuglevel(int\fR \fIlevel\fR\fB)\fR
178 \fI$pool\fR\fB\->setdebuglevel(\fR\fI$level\fR\fB)\fR;
179 \fIpool\fR\fB\&.setdebuglevel(\fR\fIlevel\fR\fB)\fR
180 \fIpool\fR\fB\&.setdebuglevel(\fR\fIlevel\fR\fB)\fR
186 Set the debug level\&. A value of zero means no debug output, the higher the value, the more output is generated\&.
192 \fBint set_flag(int\fR \fIflag\fR\fB, int\fR \fIvalue\fR\fB)\fR
193 my \fI$oldvalue\fR \fB=\fR \fI$pool\fR\fB\->set_flag(\fR\fI$flag\fR\fB,\fR \fI$value\fR\fB)\fR;
194 \fIoldvalue\fR \fB=\fR \fIpool\fR\fB\&.set_flag(\fR\fIflag\fR\fB,\fR \fIvalue\fR\fB)\fR
195 \fIoldvalue\fR \fB=\fR \fIpool\fR\fB\&.set_flag(\fR\fIflag\fR\fB,\fR \fIvalue\fR\fB)\fR
205 \fBint get_flag(int\fR \fIflag\fR\fB)\fR

207 \fIvalue\fR \fB=\fR \fIpool\fR\fB\&.get_flag(\fR\fIflag\fR\fB)\fR
208 \fIvalue\fR \fB=\fR \fIpool\fR\fB\&.get_flag(\fR\fIflag\fR\fB)\fR
214 Set/get a pool specific flag\&. The flags define how the system works, e\&.g\&. how the package manager treats obsoletes\&. The default flags should be sane for most applications, but in some cases you may want to tweak a flag, for example if you want to solv package dependencies for some other system than yours\&.
220 \fBvoid set_rootdir(const char *\fR\fIrootdir\fR\fB)\fR
221 \fI$pool\fR\fB\->set_rootdir(\fR\fIrootdir\fR\fB)\fR;
222 \fIpool\fR\fB\&.set_rootdir(\fR\fIrootdir\fR\fB)\fR
223 \fIpool\fR\fB\&.set_rootdir(\fR\fIrootdir\fR\fB)\fR
233 \fBconst char *get_rootdir()\fR
234 my \fI$rootdir\fR \fB=\fR \fI$pool\fR\fB\->get_rootdir()\fR;
235 \fIrootdir\fR \fB=\fR \fIpool\fR\fB\&.get_rootdir()\fR
236 \fIrootdir\fR \fB=\fR \fIpool\fR\fB\&.get_rootdir()\fR
242 Set/get the rootdir to use\&. This is useful if you want package management to work only in some directory, for example if you want to setup a chroot jail\&. Note that the rootdir will only be prepended to file paths if the \fBREPO_USE_ROOTDIR\fR flag is used\&.
248 \fBvoid setarch(const char *\fR\fIarch\fR \fB= 0)\fR
249 \fI$pool\fR\fB\->setarch()\fR;
250 \fIpool\fR\fB\&.setarch()\fR
251 \fIpool\fR\fB\&.setarch()\fR
257 Set the architecture for your system\&. The architecture is used to determine which packages are installable\&. It defaults to the result of \(lquname \-m\(rq\&.
263 \fBRepo *add_repo(const char *\fR\fIname\fR\fB)\fR
264 \fI$repo\fR \fB=\fR \fI$pool\fR\fB\->add_repo(\fR\fI$name\fR\fB)\fR;
265 \fIrepo\fR \fB=\fR \fIpool\fR\fB\&.add_repo(\fR\fIname\fR\fB)\fR
266 \fIrepo\fR \fB=\fR \fIpool\fR\fB\&.add_repo(\fR\fIname\fR\fB)\fR
272 Add a Repository with the specified name to the pool\&. The reposiory is empty on creation, use the repository methods to populate it with packages\&.
278 \fBRepoiterator *repos_iter()\fR
279 \fBfor my\fR \fI$repo\fR \fB(\fR\fI@\fR\fB{\fR\fI$pool\fR\fB\->repos_iter()})\fR
280 \fBfor\fR \fIrepo\fR \fBin\fR \fIpool\fR\fB\&.repos_iter():\fR
281 \fBfor\fR \fIrepo\fR \fBin\fR \fIpool\fR\fB\&.repos_iter()\fR
287 Iterate over the existing repositories\&.
293 \fBSolvableiterator *solvables_iter()\fR
294 \fBfor my\fR \fI$solvable\fR \fB(\fR\fI@\fR\fB{\fR\fI$pool\fR\fB\->solvables_iter()})\fR
295 \fBfor\fR \fIsolvable\fR \fBin\fR \fIpool\fR\fB\&.solvables_iter():\fR
296 \fBfor\fR \fIsolvable\fR \fBin\fR \fIpool\fR\fB\&.solvables_iter()\fR
302 Iterate over the existing solvables\&.
308 \fBDep *Dep(const char *\fR\fIstr\fR\fB, bool\fR \fIcreate\fR\fB=1)\fR
309 my \fI$dep\fR \fB=\fR \fI$pool\fR\fB\->Dep(\fR\fI$string\fR\fB)\fR;
310 \fIdep\fR \fB=\fR \fIpool\fR\fB\&.Dep(\fR\fIstring\fR\fB)\fR
311 \fIdep\fR \fB=\fR \fIpool\fR\fB\&.Dep(\fR\fIstring\fR\fB)\fR
317 Create an object describing a string or dependency\&. If the string is currently not in the pool and \fIcreate\fR is false, \fBundef\fR/\fBNone\fR/\fBnil\fR is returned\&.
323 \fBvoid addfileprovides()\fR
324 \fI$pool\fR\fB\->addfileprovides()\fR;
325 \fIpool\fR\fB\&.addfileprovides()\fR
326 \fIpool\fR\fB\&.addfileprovides()\fR
336 \fBQueue addfileprovides_queue()\fR
337 my \fI@ids\fR \fB=\fR \fI$pool\fR\fB\->addfileprovides_queue()\fR;
338 \fIids\fR \fB=\fR \fIpool\fR\fB\&.addfileprovides_queue()\fR
339 \fIids\fR \fB=\fR \fIpool\fR\fB\&.addfileprovides_queue()\fR
345 Some package managers like rpm allow dependencies on files contained in other packages\&. To allow libsolv to deal with those dependencies in an efficient way, you need to call the addfileprovides method after creating and reading all repositories\&. This method will scan all dependency for file names and than scan all packages for matching files\&. If a filename has been matched, it will be added to the provides list of the corresponding package\&. The addfileprovides_queue variant works the same way but returns an array containing all file dependencies\&. This information can be stored with the repository to speed up the next usage of the repository\&.
351 \fBvoid createwhatprovides()\fR
352 \fI$pool\fR\fB\->createwhatprovides()\fR;
353 \fIpool\fR\fB\&.createwhatprovides()\fR
354 \fIpool\fR\fB\&.createwhatprovides()\fR
360 Create the internal \(lqwhatprovides\(rq hash over all of the provides of all packages\&. This method must be called before doing any lookups on provides\&. It\(cqs encuraged to do it right after all repos are set up, usually right after the call to addfileprovides()\&.
366 \fBQueue whatprovides(DepId\fR \fIdep\fR\fB)\fR
367 my \fI@solvables\fR \fB=\fR \fI$pool\fR\fB\->whatprovides(\fR\fI$dep\fR\fB)\fR;

369 \fIsolvables\fR \fB=\fR \fIpool\fR\fB\&.whatprovides(\fR\fIdep\fR\fB)\fR
375 Return all solvables that provide the specified dependency\&. You can use either a Dep object or an simple Id as argument\&.
381 \fBQueue matchprovidingids(const char *\fR\fImatch\fR\fB, int\fR \fIflags\fR\fB)\fR
382 my \fI@ids\fR \fB=\fR \fI$pool\fR\fB\->matchprovidingids(\fR\fI$match\fR\fB,\fR \fI$flags\fR\fB)\fR;

384 \fIids\fR \fB=\fR \fIpool\fR\fB\&.matchprovidingids(\fR\fImatch\fR\fB,\fR \fIflags\fR\fB)\fR
390 Search the names of all provides and return the ones matching the specified string\&. See the Dataiterator class for the allowed flags\&.

444 \fIjob\fR \fB=\fR \fIpool\fR\fB\&.Job(\fR\fIhow\fR\fB,\fR \fIwhat\fR\fB)\fR
450 Create a new Job object\&. Kind of low level, in most cases you would use a Selection or Dep job constructor instead\&.
456 \fBSelection *Selection()\fR
457 my \fI$sel\fR \fB=\fR \fI$pool\fR\fB\->Selection()\fR;
458 \fIsel\fR \fB=\fR \fIpool\fR\fB\&.Selection()\fR
459 \fIsel\fR \fB=\fR \fIpool\fR\fB\&.Selection()\fR
465 Create an empty selection\&. Useful as a starting point for merging other selections\&.
471 \fBSelection *Selection_all()\fR
472 my \fI$sel\fR \fB=\fR \fI$pool\fR\fB\->Selection_all()\fR;
473 \fIsel\fR \fB=\fR \fIpool\fR\fB\&.Selection_all()\fR
474 \fIsel\fR \fB=\fR \fIpool\fR\fB\&.Selection_all()\fR
480 Create a selection containing all packages\&. Useful as starting point for intersecting other selections or for update/distupgrade jobs\&.
486 \fBSelection *select(const char *\fR\fIname\fR\fB, int\fR \fIflags\fR\fB)\fR
487 my \fI$sel\fR \fB=\fR \fI$pool\fR\fB\->select(\fR\fI$name\fR\fB,\fR \fI$flags\fR\fB)\fR;
488 \fIsel\fR \fB=\fR \fIpool\fR\fB\&.select(\fR\fIname\fR\fB,\fR \fIflags\fR\fB)\fR
489 \fIsel\fR \fB=\fR \fIpool\fR\fB\&.select(\fR\fIname\fR\fB,\fR \fIflags\fR\fB)\fR
495 Create a selection by matching packages against the specified string\&. See the Selection class for a list of flags and how to create solver jobs from a selection\&.
501 \fBvoid setpooljobs(Jobs *\fR\fIjobs\fR\fB)\fR

516 \fIjobs\fR \fB=\fR \fIpool\fR\fB\&.getpooljobs()\fR
517 \fIjobs\fR \fB=\fR \fIpool\fR\fB\&.getpooljobs()\fR
523 Get/Set fixed jobs stored in the pool\&. Those jobs are automatically appended to all solver jobs, they are meant for fixed configurations like which packages can be multiversion installed, which packages were userinstalled or must not be erased\&.
529 \fBvoid set_loadcallback(Callable *\fR\fIcallback\fR\fB)\fR
530 \fI$pool\fR\fB\->setloadcallback(\e\fR\fI&callbackfunction\fR\fB)\fR;

532 \fIpool\fR\fB\&.setloadcallback { |\fR\fIrepodata\fR\fB| \&.\&.\&. }\fR
538 Set the callback function called when repository metadata needs to be loaded on demand\&. To make use of this feature, you need to create repodata stubs that tell the library which data is available but not loaded\&. If later on the data needs to be accessed, the callback function is called with a repodata argument\&. You can then load the data (maybe fetching it first from an remote server)\&. The callback should return true if the data has been made available\&.
539 .SS "DATA RETRIEVAL METHODS"
541 In the following functions, the \fIkeyname\fR argument describes what to retrive\&. For the standard cases you can use the available Id constants\&. For example,
547 \fB$solv::SOLVABLE_SUMMARY\fR
548 \fBsolv\&.SOLVABLE_SUMMARY\fR
549 \fBSolv::SOLVABLE_SUMMARY\fR
555 selects the \(lqSummary\(rq entry of a solvable\&. The \fIsolvid\fR argument selects the desired solvable by Id\&.

1059 \fBREPO_LOCALPOOL\fR
1061 Use the repodata\(cqs pool for Id storage instead of the global pool\&. Useful if you don\(cqt want to pollute the global pool with many unneeded ids, like when storing the filelist\&.
1064 \fBREPO_USE_LOADING\fR
1066 Use the repodata that is currently being loaded instead of creating a new one\&. This only makes sense if used in a load callback\&.
1069 \fBREPO_EXTEND_SOLVABLES\fR
1071 Do not create new solvables for the new data, but match existing solvables and add the data to them\&. Repository metadata is often split into multiple parts, with one primary file describing all packages and other parts holding information that is normally not needed, like the changelog\&.
1074 \fBREPO_USE_ROOTDIR\fR
1076 Prepend the pool\(cqs rootdir to the path when doing file operations\&.
1079 \fBREPO_NO_LOCATION\fR
1081 Do not add a location element to the solvables\&. Useful if the solvables are not in the final position, so you can add the correct location later in your code\&.

1086 Do not create stubs for repository parts that can be downloaded on demand\&.
1089 \fBSUSETAGS_RECORD_SHARES\fR
1091 This is specific to the add_susetags() method\&. Susetags allows to refer to already read packages to save disk space\&. If this data sharing needs to work over multiple calls to add_susetags, you need to specify this flag so that the share information is made available to subsequent calls\&.

2214 .SH "FILE MANAGEMENT"
2216 This functions were added because libsolv uses standard \fBFILE\fR pointers to read/write files, but languages like perl have their own implementation of files\&. The libsolv functions also support decompression and compression, the algorithm is selected by looking at the file name extension\&.

2246 Create a file handle from the specified file descriptor\&. The path argument is only used to select the correct (de\-)compression algorithm, use an empty path if you want to make sure to read/write raw data\&.

2285 \fIfile\fR\fB\&.flush()\fR
2286 \fIfile\fR\fB\&.flush()\fR
2292 Flush the file\&. Returns false if there was an error\&. Flushing a closed file always returns true\&.
2299 \fI$file\fR\fB\->close()\fR;
2300 \fIfile\fR\fB\&.close()\fR
2301 \fIfile\fR\fB\&.close()\fR
2307 Close the file\&. This is needed for languages like Ruby, that do not destruct objects right after they are no longer referenced\&. In that case, it is good style to close open files so that the file descriptors are freed right away\&. Returns false if there was an error\&.
