[pacman-dev] Examples in the manpages
by Nico Schottelius 04 Oct '11

04 Oct '11

Dear pacman-devs, after a funny replace pacman-with-pacman-git evening, I digged around a bit into makepkg and pacman and noticed there are no examples in the manpages. Is that intented or would you like to/accept patches which add the EXAMPLES section? Cheers, Nico -- New PGP key: 7ED9 F7D3 6B10 81D7 0EC5 5C09 D7DC C8E4 3187 7DF0 Please resign, if you signed 9885188C or 8D0E27A4.

[pacman-dev] configurable shell for install scripts
by Allan McRae 12 May '11

12 May '11

Hi, I thought I'd run this past people on this list before I spent the two weeks that this would take me to figure out how to implement it! This is motivated by experience packaging for Arch. Install scriptlets are written assuming /bin/sh is bash, which is true on a default system. But some people want to change their /bin/sh to (e.g.) dash. As pacman uses the default shell (as given by /bin/sh) to run install scriptlets, pointing /bin/sh at dash may cause failures when bash specific features are used. So I thought, why not manually specify the shell for install scriptlets in pacman.conf. Something like "INSTALL_SHELL=/bin/sh" by default. Then _alpm_runscriptlet would call something like "<shell> -c ". <scriptlet path> && <function>" (which works for bash, dash, zsh, pdksh). Comments? Allan

[pacman-dev] New patchset for package signing
by Denis A. Altoé Falqueto 25 Nov '10

25 Nov '10

So, I changed the code to use gpgme. Here are the patches for your evaluation. By the way, I'm not {angry,upset,crying} :) I really want to see package signing in pacman, but I know that this is a complex issue that will need lots of discussion. Below, follows a little explanation of the general idea of each patch. [PATCH 1/5] pacman-key: keyring management tool The script that helps with management for pacman keyring. It uses gpg, instead of gpg2 and is heavly inpired on apt-key, from debian. It is very straightforward. [PATCH 2/5] Signature verification functions Two functions: one for signatures in memory and another for signatures in files. Signatures of packages are stored in the repository and are copied to memory before verification. The signatures of database files are stored on files, hence the new function. [PATCH 3/5] Verify the signatures of databases and packages The calls for the signature functions. Verification of database updates and package instalations from the repositories. I didn't worry about local instalations, but it doesn't mean they are not there. If it were verified before (as Dan suggests), they are there. :) A point raised by Dan was that the reading of the signature from the repository was too complex. The reaasoning behind it is that signatures grow according to the size of the key used to sign. So, we can't be never sure if some buffer size is really enough. Maybe it is enough now, but in the future it may be not and we'll have a new bug in the bugtracker. My implementation is simple and robust, so it will work with any signature size. [PATCH 4/5] Parameter to select key to sign Just a new parameter to allow the packager to select the key he wants to use. if the key is not specified, his default key will be used. [PATCH 5/5] Document new options related to package signing Just documentation. No imporant comment. As always, comments and suggestions are welcome. -- Denis A. Altoé Falqueto

[pacman-dev] 3.4.1 String freeze
by Dan McGee 02 Sep '10

02 Sep '10

Guys, We're going to be doing a 3.4.1 maint release this week, so this is a call for any minor translation updates you want to sneak in. The files are available via Transifex: http://www.transifex.net/projects/p/archlinux-pacman/ Remember that there are two projects, so you will need to submit both files if applicable. We have one outstanding translation bug on the German translation: http://bugs.archlinux.org/task/20216?project=3 Thanks! -Dan

[pacman-dev] [PATCH] Use pipe to create compressed package instead of an intermediate tar file
by Juergen Hoetzel 27 Aug '10

27 Aug '10

A pipe between tar and compression command is used. This improves performance by running tar and the compression command simultaneously. Using a pipe also reduces IO by not writing an intermediate tar file to disk.
