2008-05-13Cleanup usages of alpm_list_find and alpm_list_remove.Chantry Xavier
* 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.

2008-04-26Fix some fallout from the delta/download changesDan McGee
We removed one too many FREELIST() calls when trying to fix some memleaks, and add a safety/sanity check to ensure filename is set, as packages in old DBs are likely to not have this field. Signed-off-by: Dan McGee <dan@archlinux.org>
2008-04-26get_filename : use the FILENAME db field only.Chantry Xavier
Reference : FS#9547. The get_filename function first tries to get the filename field from the database, and if it doesn't find it, it tries to guess it based on the name, version and arch. This field was introduced in 3.0, but there are still many old entries in the official databases without it. So the databases need to be regenerated first before this patch can be applied. There is a second problem with the delta code, which needs the filename for locally installed packages too, but this field is not present in the local db. So the delta code needs to be fixed first.

2008-04-26Get rid of the delta patches listChantry Xavier
As Nathan noticed, the new informations in the delta struct allows us to get rid of this list : http://www.archlinux.org/pipermail/pacman-dev/2008-February/011163.html So I rewrote apply_deltas for that. The previous apply_deltas also had a limitation: it assumed that the initial package and the deltas were in the first cache dir, which is not necessarily the case. That situation is supported now.

2008-04-26Completely rework delta algorithmChantry Xavier
Using the graph structures that Nagy set up for dependency sorting, we now do a similar process for deltas. Load up all of the deltas into a graph object on which we can then apply Dijkstra's algorithm, using the new weight field of graph struct. We initialize the nodes weight using the base files that we can use in our filecache (both filename and md5sum must match). The algorithm then picks the best path among those that can be resolved. Note that this algorithm has a few advantages over the old one: 1. It is completely file agnostic. These delta chains do not have to consist of package files- this could be adopted to do delta-fied DBs. 2. It does not use the local_db anymore, or even care if a package or file is currently installed. Instead, it only looks in the filecache for files and packages that match delta chain entries.

2008-04-26Rework delta struct and modify code accordinglyDan McGee
Start to move the delta struct away from an assumed package name scheme and towards something that is package (or even filename) agnostic. This will allow us much greater flexibility in the usage of deltas (maybe even sync DBs some day) as well as allowing code outside of delta.h/delta.c to be much cleaner with less of a need for snprintf() calls.

2008-03-23Avoid duplicated target names.Nagy Gabor
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.

2008-03-10Remove trans->targetsNagy Gabor
Its implementation was quite broken: * add_loadtarget() might have silently filtered out some targets when replacing an older version. * This was used in sync.c to determine whether a target is implicit or not, which is incorrect behavior. Before this patch we silently removed user confirmed replacements; now we always warn on a replacement. * remove001.py behavior was quite odd in adding same target 5 times to the target list, we can change this behavior to be a failure.

2008-02-27libalpm: clean up of md5sum functions.Chantry Xavier
test_delta_md5sum and test_pkg_md5sum were simple wrappers to test_md5sum, and only used once, so not very useful. I removed them. Also, test_md5sum and alpm_pkg_checkmd5sum functions were a bit duplicated, so I refactored them with a new _alpm_test_md5sum function in libalpm/util.c Signed-off-by: Chantry Xavier <shiningxc@gmail.com>

2008-02-24Remove pmserver_t abstractionDan McGee
Remove what was a pretty weird abstraction in the libalpm backend. Instead of parsing server URLs as we get them (of which we don't usually use more than a handful anyway), wait until they are actually used, which allows us to store them as a simple string list instead. This allows us to remove a lot of code, and will greatly simplify the continuing refactoring of the download code. Signed-off-by: Dan McGee <dan@archlinux.org>

Instead of using type = UPGRADE or DEPEND, we now rather use a "pmpkgreason_t newreason" field directly (= explicit or depend) which allows a better handling of the install reason.

2008-01-23libalpm/sync.c : conflicts resolving cleanup.Chantry Xavier
The original patch from Nagy tried to resolve target vs target conflicts, and so broke the following pactests : sync040, sync041 and sync990 Nagy's proposal to solve this situation was to choose the interactive way, ask the user how to deal with it: either remove pkg1 or remove pkg2 or stop here. So he left this as a TODO. But instead of trying to resolve these conflicts or asking the user, I tried to find a more conservative way, looking at what the current pactests expected: If between the two conflicting packages, one provides the other, pacman will keep that one and remove the other from the target list. That breaks sync893 and sync897. But Dan agreed these two looked weird and should be changed. This commit should close FS#8897, FS#8899 and FS#9024.

2008-01-23Add new public alpm_checkdbconflicts function.Chantry Xavier
This function has a limited purpose, but might be interesting to do a sanity check from a frontend (eg testdb). Also removed the private _alpm_checkconflicts function to avoid confusion. This function was used only once in libalpm, in sync.c, and was just a single line anyway. Having to do it manually makes it explicit that we are looking for two kind of conflicts (targ vs targ and db vs targ).

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.

2008-01-09Move the fallback on providers from backend to frontend.Chantry Xavier
This reverts commit e28973169d2e5eda8b64ebdda11ece0dc761d978. This code might fit better in the frontend than in the backend finally. Ref: http://www.archlinux.org/pipermail/pacman-dev/2007-November/010150.html I also changed it for fixing FS#8763 : if there is exactly one provider, pacman will pull it and print a warning. if there are several providers, pacman will list them and fail. It's up to the user to pick one. Add sync501 pactest to reflect that.

2007-12-02Add new --needed option for -S.Chantry Xavier
During a pacman operation such as a group install, pacman can ask several questions such as "local version is up to date. Upgrade anyway?". They are usually all answered either by yes or by no: * yes when you want to reinstall all the targets. * no when you only want to install the missing ones (either because you are installing a group, or because you are copying a pacman -S line from wiki or whatever). So instead of asking this question for each target, it is now now configured with a flag. Yes will be the default -S behavior, No will be achieved with the --needed flag.

2007-11-18Add the pmconflict_t type.Nagy Gabor
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>
