* sortbydeps: include local pkgs in dep graphAndrew Gregory2013-10-31
| | | | | | | | | | | | | | | | Detecting indirect dependencies by traversing a package's entire dependency tree is prohibitively slow for larger transactions. Instead add local packages to the dependency graph. This additionally requires delaying dependency ordering for sync operations so that removed packages may be excluded from dependency detection. tests/sync012.py was also updated to ensure that the dependency cycle was actually detected.

* Be more robust when copying package dataDan McGee2011-08-19
| | | | | | | | | | | | | | | | This changes the signature of _alpm_pkg_dup() to return an integer error code and provide the new package in a passed pointer argument. All callers are now more robust with checking the return value of this function to ensure a fatal error did not occur. We allow load failures to proceed as otherwise we have a chicken and egg problem- if a 'desc' local database entry is missing, the best way of restoring said file is `pacman -Sf --dbonly packagename`. This patch fixes a segfault that was occurring in this case. Fixes the segfault reported in FS#25667. Signed-off-by: Dan McGee <dan@archlinux.org>

* Ensure reported missing dependencies show correct version comparisonDan McGee2011-03-25
| | | | | | | | | | | | This addresses FS#23424. The -dd backend code was introduced in commit b6ec9019d77, and unfortunately the munged depend used for comparison did not carry through to the eventual display of this version. To fix this, we undo some of the depcmp_tolerant() business introduced, and instead make a new pmdepend_t object if necessary when the no dependency version flag is set. This results in the correct depend being copied to the missing depend passed onto the frontend. Signed-off-by: Dan McGee <dan@archlinux.org>

* alpm/depcmp: new NODEPVERSION flagXavier Chantry2011-01-31
| | | | | | | | | | | | | | | | This flag allows to disable version checking in dependency resolving code. depcmp_tolerant respects the NODEPVERSION flag but we still keep the original strict depcmp. The idea is to reduce the impact of the NODEPVERSION flag by using it in fewer places. I replaced almost all depcmp calls by depcmp_tolerant in deps.c (except in the public find_satisfier used by deptest / pacman -T), but I kept depcmp in sync.c and conflict.c Signed-off-by: Xavier Chantry <chantry.xavier@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>

* alpm: don't expose alpm_depcmpXavier Chantry2010-12-12
| | | | | | | | | | | | | Either we expose all low levels function dealing with pmdepend_t (splitdep and depfree come to mind), or we don't. Since none of the tools use depcmp, I chose to remove it. In the future, we might want to expose higher level functions such as alpm_find_satisfier, or just lower level functions like splitdep and depfree together with depcmp.

* Partial fix for the phonon/qt issueNagy Gabor2010-05-18
| | | | | | | | | | | | | | | | | This patch fixes the phonon/qt issue, if all to-be-upgraded packages are explicit targets (ie. only not-yet-installed packages are pulled by resolvedeps). This condition covers the most common situations, for example it should hold with every -Su operation. After this patch sync405.py passes, but sync406.py doesn't. The work is inspired by the patch of Henning Garus, thanks for his work: http://mailman.archlinux.org/pipermail/pacman-dev/2010-February/010429.html (I moved the alpm_list_diff computation to sync.c in order to compute it only once.)

* Look in target-list first to resolve dependenciesBryan Ischo2009-04-11
| | | | | | | | | | | | | | | This fixes a bug introduced by my previous changes which changes the behavior of IgnorePkg/IgnoreGroup to allow the user to remove unresolvable packages from the transaction. The bug is that the target-list was no longer being consulted first to resolve dependencies, which means that if two packages in the sync database satisfied a dependency, and the user explicitly requested one of those two packages in the sync, the other package was still being pulled in. A new test was added, sync993.py, to verify the desired behavior. Signed-off-by: Bryan Ischo <bji-keyword-pacman.3644cb@www.ischo.com> Signed-off-by: Dan McGee <dan@archlinux.org>

* Reorganize code for one-at-a-time resolvingBryan Ischo2009-02-18
| | | | | | | | | | | | This change reorganizes the internal code so that packages are resolved one at a time instead of all at once from a list. This will allow a future checkin to prompt the user to see if they'd rather remove unresolvable packages from the transaction and continue, or fail the transaction.

* sync_addtarget reworkNagy Gabor2008-07-13
| | | | | | | | | | | | | | | | | | | | | | Now '-S provision' handling is done in the back-end. In case of multiple providers, the first one is selected (behavior change: deleted provision002.py). The old processing order was: literal, group, provision; the new one: literal, provision, group. This is more rational, but "pacman -S group" will be slower now. "pacman -S repo/provision" also works. Provision was generalized to dependencies, so you can resolve deps by hand: "pacman -S 'bash>2.0'" or "pacman -S 'core/bash>2.0'" etc. This can be useful in makepkg dependency resolving. The changes were documented in pacman manual. alpm_find_pkg_satisfiers and _alpm_find_dep_satisfiers functions were removed, since they are no longer needed. I added some verbosity to "select provider instead of literal" and "fallback to group". Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>
* Resolvedeps reworkNagy Gabor2008-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I divided resolvedeps into 2 functions. The new _alpm_resolvedep function will resolve one dependency, for example the 'foo>=1.0-1' dependency. It can be useful in sync_addtarget refactoring. The resolvedeps parameters were changed, to be coherent with recursedeps: * the target-list is an alpm_list* instead of alpm_list**. This is OK, because alpm_list_add == alpm_list_add_last * syncpkg param was removed. list contains the to-be-installed packages, resolvedeps will add the required dependencies into this list * trans param was removed, it was used in QUESTION() only, which can be used on the main (handle->trans) transaction only (because the front-end cannot access our pseudo-transactions at all!). The patch fixes some wrong dynamic pmdepmissing_t usage. I did a behavior change (and sync1003.py was modified accordingly), which needs some explanation: The old resolvedeps didn't elect packages from 'remove' list. I've dropped this because I don't want that 2nd excluding list param. In fact, in real life, we ~never need this rule. Resolvedeps is called before checkconflicts, so only -Su's %REPLACES% packages are sitting in 'remove' list. This means, that we have the replacement packages in our target list. Usually "foo replaces bar" means, that bar isn't in our repos any more, so resolvedeps *cannot* elect it; but usually it won't try it at all, because foo is in the target list, and it is expected to satisfy 'bar>=1.0-1'-like dependencies too. Since checkdeps and checkconflicts is done after resolvedeps, this cannot cause any harm. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>

This commit actually get rids of all complicated and asymmetric _cmp functions. I first thought these functions were worth it, be caused it allowed us to reuse list_find and list_remove. But this was at the detriment of the clarity and also the ease of use of these functions, dangerous because of their asymmetricity.

* New remove option : -u / --unneeded (FS#6505).Nagy Gabor2008-02-06
| | | | | | | | | | | | | | | | | With --unneeded option 'pacman -R' doesn't stop in case of dependency error; it removes the needed-dependency targets from the target-list instead. See also: http://archlinux.org/pipermail/pacman-dev/2007-October/009653.html . The patch also adds a new causingpkg field to pmdepmissing_t which indicates the to-be-removed package which would cause a dependency break. This is needed, because miss->depend.name may be a provision. miss->causingpkg will be useful in -R dependency error messages too. [Xavier: renamed inducer to causingpkg, removed the _alpm_pkgname_pkg_cmp helper function as requested by Aaron. This might be added by a further commit.

* Move the deptest code from frontend to backend.Chantry Xavier2008-01-21
| | | | | | | | | | | | | | | | | | The deptest code (pacman -T) used by makepkg was mostly in the frontend. There were 2 drawbacks: 1) the public splitdep function returns a pmdepend_t struct, but the _alpm_dep_free function for freeing it is private. So there was a memleak. 2) there is a helper in the backend (satisfycmp in deps.c) which makes this function much easier. So this adds a new public alpm_deptest in libalpm/deps.c, which cleans pacman_deptest in pacman/deptest.c a lot. Besides, alpm_splitdep was made private, because the frontend no longer requires it, and _alpm_dep_free is also private. Finally the deptest001 pactest was extended.

* Add functions to manipulate pmdepend_t objectsDan McGee2008-01-11
| | | | | | | | | | | We didn't have a free function before, causing some memory leaks. We also need a dup function now that strings are not in the structure but are dynamically allocated. Also adapt pmdepmissing_t to use a pointer to a depend struct instead of an inclusive one so we can use the functions we created here. Signed-off-by: Dan McGee <dan@archlinux.org>
* Use dynamic string allocation in package structuresDan McGee2008-01-11
| | | | | | | | | | | | | | This also affects all structures with static strings, such as depmiss, conflict, etc. This should help a lot with memory usage, and hopefully make things a bit more "idiot proof". Currently our pactest pass/fail rate is identical before and after this patch. This is not to say it is a perfect patch- I have yet to pull valgrind out. However, this should be quite safe to use in all situations from here on out, and we can start plugging the memleaks.

* Add the pmconflict_t type.Nagy Gabor2007-11-18
| | | | | | | | | | | | | | | | | | pmdepmissing_t was used for two totally different things : missing dependencies, and dependency conflicts. So this patch simply adds a type for dep conflicts, and convert the code to use it. This fix the TODO in conflict.c : /* TODO WTF is a 'depmissing' doing indicating a conflict? */ Additionally, the code in conflict.c now eliminates the duplicated conflicts. If pkg1 conflicts with pkg2, and pkg2 conflicts with pkg1, only one of them will be stored. However the conflict handling in sync_prepare (sync.c) is still very asymetrical, and very ugly too. This should be improved in the future (there is already a pending patch from Nagy that cleans it a lot). Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
