* Improve mbasename performanceDan McGee2011-01-22
| | | | | | | Rather than roll our own, use strrchr() instead, which glibc may have a better implementation than the simple iteration method we were using. Signed-off-by: Dan McGee <dan@archlinux.org>

* Add wrapper around asprintf callsAllan McRae2010-09-27
| | | | | | | | | | | Not checking the return value of asprintf calls reuslts in a warning when using -D_FORTIRFY_SOURCE=2. This adds a simple wrapper around asprintf calls which checks the return value. Currently the check does nothing more than outputing a message to stderr on failure, but that is at least an improvement over silent failures. Signed-off-by: Allan McRae <allan@archlinux.org>

* fgets invocation cleanupDan McGee2010-08-23
| | | | | | | | | | | | | | From the fgets manpage: fgets() reads in at most one less than size characters from stream and stores them into the buffer pointed to by s. Reading stops after an EOF or a newline. If a newline is read, it is stored into the buffer. A '\0' is stored after the last character in the buffer. This means there is no need at all to do 'size - 1' math. Remove all of that and just use sizeof() for simplicity on the buffer we plan on reading into. Signed-off-by: Dan McGee <dan@archlinux.org>

* Introduce -D, --databaseNagy Gabor2010-05-05
| | | | | | | | | | | | | The request of FS#12950 is implemented. On the backend side, I introduced a new function, alpm_db_set_pkgreason(), to modify the install reason of a package in the local database. On the front-end side, I introduced a new main operation, -D/--database, which has two options, --asdeps and --asexplicit. I documented this in pacman manual.

* Remove trailing whitespace on all lines in list_displayDan McGee2009-12-13
| | | | | | | | | | | | | | | | This ensures we never have trailing whitespace. Take the following text, with line numbers added for clarity: 1. Title : item1 item2 item3 item4 2. item5 item6 item7 item8 3. item9 itemA itemB itemC Laszlo Papp helpfully pointed out we would have two trailing spaces on line three after the last item. However, we also had these trailing spaces on lines one and two, which the initial patch didn't take care of. This can be seen on something like `pacman -Qi glibc`.

| | | | | | | | | | | | | | | | | | | | Thanks to Laszlo Papp <djszapi@archlinux.us> for the following catch: opendir(path)) == (DIR *)-1; is maybe the result of misunderstanding the manpage.

* We don't need root with -SpNagy Gabor2009-06-01
| | | | | | | | | | | | FS#8905 is fixed. The front-end passes PM_TRANS_FLAG_NOLOCK to the back-end, so it doesn't lock the database. That's why we don't need root anymore. I reworked (and renamed) needs_transaction() accordingly. I also added missing -Sc check there (for example, -Sci didn't print non-root error, but pacman wanted to lock the database).

* Remove pmsyncpkg_tNagy Gabor2009-04-11
| | | | | | | | | | | | | | | | | | | | | pmsyncpkg_t data sructure was removed: 1. pmpkg_t.reason is used instead of pmsyncpkg_t.newreason. (The target packages come from sync repos, so we can use this field without any problems. Upgrade transaction also uses this field to store this info.) 2. pmsyncpkg_t.removes was moved to pmpkg_t.removes. This step requires careful programming, because we don't duplicate packages when we add them to trans->packages. So we modify sync pkgcache when we add this transaction-only info to our package. Hence it is important to free this list when we remove any package from the target list (remove_unresolvable, remove_conflicts, trans_free), otherwise this could confuse the new sync transactions (with non-pacman GUI). Overall, our code became ~100 line shorter, and we can call our helper functions directly on trans->packages in sync.c, we don't need to maintain parallel package lists.

Having to specify preset==1 for all the other cases was rather cumbersome.

| | | | | | | | | | | | | | | | | | | | We had a lot of duplicated code here. The code handling the showsize option needed to be there three times : 1) for install part of -S 2) for remove part of -S (conflict removal) 3) for -R This patch introduce a new display_targets(pkglist, install) function which can handle the 3 cases above. We pass install == 1 for case 1), and install == 0 for case 2) and 3). Now we can finally get the benefit of an old patch which handled the ShowSize option consistently in the 3 cases above, without an awful lot of duplicated code : http://www.archlinux.org/pipermail/pacman-dev/2008-January/011029.html Signed-off-by: Xavier Chantry <shiningxc@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>

* Use correct C type for file sizesDan McGee2008-06-04
| | | | | | | | | | | | | | We have been using unsigned long as a file size type for a while, which works but isn't quite correct and could easily break. Worse was probably our use of int in the download callback functions, which could be restrictive for packages > 2GB in size. Switch all file size variables to use off_t, which is the preferred type for file sizes. Note that at least on Linux, all applications compiled against libalpm must now be sure to use large file support, where _FILE_OFFSET_BITS is defined to be 64 or there will be some weird issues that crop up.

* Completely rework delta algorithmChantry Xavier2008-04-26
| | | | | | | | | | | | | | | | | | | | 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.
