2008-05-13Cleanup usages of alpm_list_find and alpm_list_remove.Chantry Xavier1-9/+29
* 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.

2008-04-25Kill compute_requiredby usage in can_remove_package()Nagy Gabor1-8/+10
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.

2008-03-23Avoid duplicated target names.Nagy Gabor1-2/+4
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.

2008-02-16Move pmgraph_t struct and functions to their own header fileDan McGee1-27/+3
This will allow us to utilize this helpful type and functions in places besides dependency calculations. In addition, remove the public declaration of pmgraph_t in alpm.h- there is zero need to expose this internal type. Signed-off-by: Dan McGee <dan@archlinux.org>
2008-02-06New remove option : -u / --unneeded (FS#6505).Nagy Gabor1-4/+18
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. Other small cleanups, updated manpage and bash completion.] Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
2008-01-23Fix flip-flopped parameters to CALLOC macroDan McGee1-2/+2

2008-01-21Move the deptest code from frontend to backend.Chantry Xavier1-1/+26
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.

2008-01-14Change the versioned provision format.Chantry Xavier1-2/+2
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.

Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> [Xav: In my opinion, computing both dblist and modified in one for loop also makes the code clearer, besides being more efficient.

2008-01-11Add functions to manipulate pmdepend_t objectsDan McGee1-21/+32
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>
2008-01-11Use dynamic string allocation in package structuresDan McGee1-18/+39
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.

2007-11-30Remove alpm_depcmp DEBUG outputDan McGee1-4/+0
alpm_depcmp is simple enough that we shouldn't need constant debug logging, and the logging we do have in there negatively impacts our speed regardless of whether we actually are seeing it or not.

2007-11-25Fix for sync1003 and sync1004 pactestsNagy Gabor1-164/+121
checkdeps and resolvedeps now take both a remove list and an install list as arguments, allowing dependencies to be calculated correctly. This broke the sync990 pactest, but this pactest used dependencies and provides in an unusual way, so it has been changed. Dan: the sync990 pactest was just plain wrong. It didn't satisfy the dependencies correctly, so should never have succeeded.

2007-11-18Add the pmconflict_t type.Nagy Gabor1-22/+7
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>

2007-11-14Move alpm_splitdep usage to db_readDan McGee1-26/+11
Holy inefficient batman! For a pacman -Qt operation (when we are using compute_requiredby and not database entries), splitdep was being called ~1.3 million times on my local database. By splitting when we read the DB, we drop this number to around 1700 and save a LOT of time in doing so (a 5x increase in pacman -Qt speed here). Note that the depends alpm_list_t in the package struct is no longer a string list, but a list of pmdepent_t objects. Signed-off-by: Dan McGee <dan@archlinux.org>
2007-11-14Remove REQUIREDBY usage from libalpmDan McGee1-6/+17
Instead of using the often-busted REQUIREDBY entries in the pacman database, compute them each time they are required. This should help many things: 1. Simplify the codebase 2. Prevent future database corruption 3. Ensure when we do use requiredby, it is always correct 4. Shrink the pmpkg_t memory overhead Signed-off-by: Dan McGee <dan@archlinux.org>
2007-11-14alpm_list_add == alpm_list_add_lastNagy Gabor1-26/+17
It's time to define that alpm_list_add(list, foo) adds 'foo' to the end of 'list' and returns with 'list', because: 1. list is a list, not a set. 2. sortbydeps _needs_ an alpm_list_add definition to work properly. As a first step, I used this definition in recursedeps.

2007-10-29libalpm: introduce MALLOC and CALLOC macrosDan McGee1-15/+6
These macros take the place of the common 4 or 5 line blocks of code we had in most places that called malloc or calloc. This should reduce some code duplication and make memory allocation more standard in libalpm. Highlights: * Note that the MALLOC macro actually uses calloc, this is just for safety so that memory is initialized to 0. This can be easily changed in one place. * One malloc call was completely eliminated- it made more sense to do it on the stack. * The use of RET_ERR in public functions (mainly the alpm_*_new functions) was standardized, this makes sense so pm_errno is set.
