[pacman-dev] md5sum check script
by Xavier 23 Apr '07

23 Apr '07

Hello, I started writing a script last week, but I think I'm pretty bad at this. IMO, it's ugly, long, complicated, slow and unsafe. I'm sending it not for usage, but since I don't see any progress, I thought maybe you could pick some ideas for writing a better one :) Now a little description of what it does : it takes the list of NoUpgrade config in /etc/pacman.conf . If it doesn't find any, it takes the default list in pacman2. It then builds the list of packages owning these files, and stores the result temporary in /tmp/backup/ It then checks if the package are available in the cache (/var/cache/pacman/pkg), if not, it tries to download them. If it's still can't download it, it'll just use a fake md5sum (0^32) for the config files in this package. Then, for each package, it'll go look at the md5sum of its config files in /var/lib/pacman/local , and compare them with the md5sum from the original package. If they are different, it's wrong, and was most certainly caused by NoUpgrade. If this file was indeed in the NoUpgrade array, and additionally the md5sum stored in the local database is the same than the md5sum of the config in the filesystem, then everything confirms that it's wrong, and the script is happy. Note : there are already 2 places where root is needed, just for checking : for downloading the missing packages, and for reading the config files in the filesystem only readable by root, like /etc/shadow. I used sudo for these 2 lines. It would then also be needed for actually correcting the md5sum.

[pacman-dev] duplicated ldconfig after -S
by Nagy Gabor 22 Apr '07

22 Apr '07

Hi! We fixed the bug that -U doesn't run ldconfig, but now in case of -S ldconfig runs twice, because -S induces and upgrade transaction too. So _alpm_ldconfig can be removed from _alpm_sync_commit. Anyway, I don't like this "pseudo-transaction" way, at least we should use different transaction types (see my PM_TRANS_TYPE_UPGRADERM patch). I think some depcheck codes should be moved to deps.c from sync.c. Bye, ngaba

[pacman-dev] _alpm_sortbydeps is slow and buggy
by Nagy Gabor 21 Apr '07

21 Apr '07

Hi! I don't really understand how this function does 'topological sorting', but it is buggy. If n is the number of targets, maxscans=sqrt(n) is not enough: See the following example: Let the targets foo[1], ... foo[n]; where foo[i] depends on foo[j] iff i<j. It's easy to see that the function would sort correctly these target in 'n-1' steps; but it is stopped after sqrt(n) steps. (libm seems to be needed for libalpm because of these _one_ sqrt() only, so libm "depend" should be removed too). In the example above O(n^3) operations needed (+ I think first compute the dependency graph would much more effective; because for example we compute (n-1) times that foo[n-1] depends on foo[n], which is needless.). Well known O(n+e)~O(n^2) algorithms exists for topological sorting (see google). And I'm not sure that even maxscans=n enough (I cannot prove that this algorithm is correct yet, this is probably my fault;), and I cannot find an extreme example where this algorithm sucks. Bye, Nagy Gabor

[pacman-dev] spanish translation for pacman
by Juan Pablo González T. 21 Apr '07

21 Apr '07

hi.. the last month i wrote a question for a spanish pacman translation. Finally we did it, with the invaluable help of Gustavo Chain, member of this mail list. well, less words, more action. the files attached are translation of pacman and libalpm for the "es" locale. Please, add to the cvs. thanks __________________________________________________ Correo Yahoo! Espacio para todos tus mensajes, antivirus y antispam ¡gratis!
