* 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>
* Print warning in _alpm_resolvedep() if a satisfier package is ignored ↵Nagy Gabor2009-04-11
| | | | | | | | | | | | | without QUESTION After commit f57f8d33862050acc8d131710c100ba47877e675 pacman *silently* ignores packages from IgnorePkg/IgnoreGroup during dependency resolving, if prompt == 0. This behavior is changed to "give warning + ignore". (Otherwise the user is not informed about the fact that the package resolving was blocked by ignorepkg.)

* New error type: PM_ERR_PKG_IGNOREDNagy Gabor2009-04-11
| | | | | | | | | | This patch fixes FS#12059. Now sync_addtarget can return with PM_ERR_PKG_IGNORED, which indicates that although the requested package was found it is in ignorepkg, so alpm could not add it to the transaction. So the front-end can decide what to do. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>

* Enabled new interactive prompt and updated some testsBryan Ischo2009-02-23
| | | | | | | | | | | | | | | Enabled a new prompt to ask the user if they'd like to remove unresolvable packages from the transaction rather than failing it. Many pactest tests that used to fail now return success codes, because pacman now issues a prompt allowing the user to cancel rather than failing many transactions, and the pactest scripts always choose to cancel with no error rather than failing. The only net effect is that the return status of pacman is now 0 in cases where it used to be nonzero. Signed-off-by: Bryan Ischo <bryan@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. This change does not affect the actual behavior of libalpm and all tests pass without changes. Signed-off-by: Bryan Ischo <bryan@ischo.com> Signed-off-by: Dan McGee <dan@archlinux.org>

* 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.

* Avoid duplicated target names.Nagy Gabor2008-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | This patch should avoid duplicated target names in the backend. 1. sync_loadtarget will return with PM_ERR_TRANS_DUP_TARGET when trying to add a duplicated target 2. sysupgrade never pulls duplicated targets 3. resolvedeps won't pull duplicated targets anymore A pulled list was introduced in sync_prepare to improve the pmsyncpkg_t<->pmpkg_t list conversion by making it more direct. Also replace sync1005 and sync1006 by the sync1008 pactest, which is similar but more interesting (the provisions are dependencies instead of explicit targets). sync1005 didn't work as expected anyway. It was expecting that pacman failed, and pacman indeed failed, but not for the good reason. It didn't fail during the preparation step because of conflicting targets, but during the commit step, because of a md5 error... And sync1006 didn't pass and was not really worth fixing. We have already enough failing pactests more important than these two. sync1008 pass with this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the 'provname provver' format to 'provname=provver'. In .PKGINFO, the provisions are copied from the PKGBUILD without quotes. So the provision version was actually handled as a different provision... See FS#9171. Dan: Unfortunately we have to change our original specification for versioned provisions with this patch, but it ends up being the simpler and cleaner solution in the long run, and if there is any time to change it the time is now before many packages have been built. Keeping the ' ' based format would have required us to do special parsing in repo-add, as well as being susceptible to users not using quotes in their provides array. Hopefully this will resolve the issues we had with our initial plan. Sorry for the confusion.

| | | | | | | | | | | | | | | | | | 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.
