* Change checkdeps and checkdbconflicts to be more flexible.Xavier Chantry2008-08-25
| | | | | | | | These two functions now take directly a package list rather than a database. checkdbconflicts was renamed to checkconflicts. Signed-off-by: Xavier Chantry <shiningxc@gmail.com>

* 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>
* Swap parameters on PM_TRANS_CONV_INSTALL_IGNOREPKG callback functionNagy Gabor2008-07-07
| | | | | | | | | | | | | | | PM_TRANS_CONV_INSTALL_IGNOREPKG callback function can get 2 params: foo, bar in this order (packages), bar can be NULL. Old API: foo, NULL: Do you want to install foo from IgnorePkg? foo, bar: foo requires bar from IgnorePkg. Do you want to install bar? New API: foo, bar: Do you want to install foo from IgnorePkg?

* New _alpm_find_dep_satisfier functionNagy Gabor2008-07-07
| | | | | | | | | | This function finds the first satisfier package in a pkglist. Using it instead of _alpm_find_dep_satisfiers eliminates some memleaks and it is faster.

* Cleanup usages of alpm_list_find and alpm_list_remove.Chantry Xavier2008-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * remove obsolete and unused *_cmp helper functions like deppkg_cmp and _alpm_grp_cmp * new alpm_list_remove_str function, used 6 times in handle.c * remove _alpm_prov_cmp / _alpm_db_whatprovides and replace them by a more general alpm_find_pkg_satisfiers with a cleaner implementation. before: alpm_db_whatprovides(db, targ) after: alpm_find_pkg_satisfiers(alpm_db_getpkgcache(db), targ) * remove satisfycmp and replace alpm_list_find + satisfycmp usage by _alpm_find_dep_satisfiers. before : alpm_list_find(_alpm_db_get_pkgcache(db), dep, satisfycmp) after : _alpm_find_dep_satisfiers(_alpm_db_get_pkgcache(db), dep) * remove _alpm_pkgname_pkg_cmp, which was used with alpm_list_remove, and use _alpm_pkg_find + alpm_list_remove with _alpm_pkg_cmp instead. 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.

* Kill compute_requiredby usage in can_remove_package()Nagy Gabor2008-04-25
| | | | | | | | | | | | | In the can_remove_package function, we don't need to compute the whole requiredby list, we just need to find one member of it that doesn't belong to the targets list. That way we get a small speedup and remove the only usage of alpm_pkg_compute_requiredby in the backend, so that it can be tweaked for frontend usage.

* 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.

* | 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.

| * Change the versioned provision format.Chantry Xavier2008-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | 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>
