Hi I'm shameem, newbie. I've nailed down the basics of shell scripting. I'd like to contribute to pacman and other official projects. Any other skills that you'd recommend me to learn along with the process ? Thank You.

[pacman-dev] Variable execution time for pacman -Qdt?
by Will S 08 Aug '17

08 Aug '17

I have noticed that the first time I run pacman -Qdt after not running it for a while it can take a variable amount of time -- usually at least 20 seconds and as long as one minute. If I run it again shortly after that it completes in less than a second. Is there a simple explanation for this variation? I have 1705 packages installed and pacman -Qdt lists 26. The reason I'd like it to be fast is that yaourt calls this command before a system update, so I get a 20-60 second lag before being prompted for my password for sudo pacman -Syu.

Yeah, that. Although now I am starting to think... I don't have any PKGBUILDs that do this myself. So it's never really been on my radar. However, I am wondering if it would make more sense to allow/use: - $SRCDEST/$repo for the submodule url. The variable should be accessible, we just don't document its availability for use in a PKGBUILD. - Implement noextract=() for source/git.sh to avoid having two checkouts with that ugly layer of indirection. - Update the "VCS package guidelines" wiki page -- Eli Schwartz

[pacman-dev] Repository management
by Allan McRae 30 Jul '17

30 Jul '17

Hi all, Every time I attempt to work on repo-add, I find it to be a very difficult endeavour. Even though it is half the size of makepkg (without even including any of libmakepkg), it is much more convoluted to work on. We also have a weird repository database system. We have: - .db dbs with package information, signatures and delta information - .files dbs that are the same as .db dbs but additionally include filelists There are two reasons the .files dbs replicate all information in the .db dbs - .db and .files dbs getting out of sync could cause issues - a complete database is useful for things like archweb, mostly to avoid the above I would also like to include information on source packages to these databases. The files information is separate due to wanting our primary database to be small. Likewise, source package information needs to be separate (the signatures take most of the size in the .db dbs, so adding source package signatures effectively doubles the size). So two points up for discussion: 1) Sync repository layout? I don't see any point in leaving the tar based format, as reading of sync databases is not a bottleneck. (The local db format can be a bottleneck, but that is a separate discussion...) Do we split the information in .db out of .files and add a .full db with complete information? Then any .src db could follow suit and just have source package information. How do we get around the out of sync issue (e.g., a package is removed from .db, but we have an old .files database with it). Do we add timestamps, and print a warning on -F operations when the two are out of sync? 2) Do we need a better (read "more easily maintainable") tool for handling database generation and updates? libalpm already can read in information package files, so we could add libalpm/db_write.c with the database creation functions. Should we unify our repo format with our local database format which we already write? I am looking for ideas here. Please brainstorm to your hearts content. Cheers, Allan

[pacman-dev] Outdated comments in pacman.conf
by Andrey Azarov 16 Jul '17

16 Jul '17

Hello! I found what comments in ls /etc/pacman.conf about signature verification is out of date: # By default, pacman accepts packages signed by keys that its local keyring > # trusts (see pacman-key and its man page), as well as unsigned packages. > SigLevel = Required DatabaseOptional > LocalFileSigLevel = Optional > #RemoteFileSigLevel = Required So I propose following changes to make comments consistent with default settings: # By default, pacman accepts only packages signed by keys that its local > keyring trusts (see pacman-key and its man page) > # The only exclusion is packages from local filesystem, such packages can > be unsigned > SigLevel = Required DatabaseOptional > LocalFileSigLevel = Optional > #RemoteFileSigLevel = Required I include svn patch in attachments. With best wishes, Andrey
