[pacman-dev] alpm_list regex matching

[pacman-dev] pacman-contrib package
by Allan McRae 27 May '08

27 May '08

Hi everyone, With the release of pacman 3.1.2 I was reminded to get around to putting a pacman-contrib package into AUR/community like I said I would [1]. I have categorized the files in the contrib directory below. Utilities: pacdiff pacsearch re-pacman (needs some updates? [2]) wget-xdelta.sh vim: PKGBUILD.vim vimproject (needs updated - developer use only) Included in pacman package: bash_completion zsh_completion Old: gensync updatesync I think the pacman-contib package should only include pacdiff, pacserach, re-pacman, PKGBUILD.vim. I did a very quick review of the files to check if they still work with the current pacman. As far as I can tell pacdiff and pacsearch don't need updated. I will look into updating re-pacman as I don't see any commits to this file since [2]. No idea about the status with PKGBUILD.vim - I don't use vim for PKGBUILDs so can someone else comment here. Any comments on the status of these scripts or list of scripts to be included? Thanks, Allan [1] http://www.archlinux.org/pipermail/pacman-dev/2008-February/011076.html [2] http://www.archlinux.org/pipermail/pacman-dev/2008-January/010788.html

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.

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.

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.

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.

[pacman-dev] [PATCH] Refactor the trans init and release code.
by Chantry Xavier 26 Apr '08

26 Apr '08

The calls to alpm_trans_init and alpm_trans_release (+ error checking) were duplicated between remove.c, sync.c and upgrade.c This patch introduces trans_init and trans_release functions in util.c to have this code just once.
