Working on SandboxUser patch
by Allan McRae 12 Feb '23

12 Feb '23

Just to avoid any potential overlap - I am working on the SandboxUser patch that Remi submitted a long while ago... https://lists.archlinux.org/archives/list/pacman-dev@lists.archlinux.org/th… The patch is far too big for me to confidently review in one go, so I am splitting it into smaller sections as I go. Progress can be seen here: https://gitlab.archlinux.org/pacman/pacman/-/commits/allan/privsep Allan

[Important] Gitlab migation plan for Pacman
by Morten Linderud 03 Jan '23

03 Jan '23

Hi, Some time ago it was decided to migrate the pacman development from the Mailing List to the Gitlab instance hosted by Arch Linux. The pacman source has been hosted there for a while but the development has strictly been conducted on the Mailing List and this is about to change. https://gitlab.archlinux.org/pacman/pacman/ The plan is as follows: 1. Open the patch submission via Gitlab and close the mailing list submission 2. Open the Gitlab issue tracker and close down the flyspry issue tracker 3. Manually migrate bugs from flyspry to Gitlab and close the others. Currently the issue tracker is open on Gitlab, and merge requests have also been enabled for some time. No EOL dates has been set on on patch submission nor flyspry, but I'd encourage any new development to using gitlab instead of the mailing list and flyspry from this point on. I propose we close down Flyspry and patch submission 1st of January 2023. This change also implies decommisioning the Patchwork instance. For this to be done we need to keep track of any unmerged/unreviewed patches from the mailing list. This list has been made and if anything is missing please do reach out. https://gitlab.archlinux.org/pacman/pacman/-/issues/1 There is also some documentation work that needs to be done to direct users from the Mailing List to Gitlab. Any help updating this documentation is very much appreciated. Cheers, Morten Linderud

RFC: Simple package diff
by Allan McRae 13 Dec '22

13 Dec '22

The idea of package deltas just won't go away... However, binary diffs really are not ideal with pacman verifying the compressed package - that means we need to reconstruct the package on the users system to verify. Also our old approach using xdelta3 somewhat died when moving packages away from gz (or xz?) compression. Other binary diff approaches really suffered the same issue. In general, I find the approach of reconstructing the full package to be suboptimal. I also don't particulaly want to verify uncompressed packages. I wondered if this was a case of perfect being the enemy of good, so I have investigated a different, very lazy approach. Instead of taking a binary diff, we could just provide the files that have changed between package versions. This is super easy to do as we have checksums for all files in the mtree file. We could then extract this "diff" package directly, and use the mtree file to adjust timestamps/permissions/etc(?) on kept files, and it would be just like the full package had been installed. I ran some numbers to see if this was worth while. The results for the last bunch of updates for bash, coreutils, qt5-base and systemd are given here: https://wiki.archlinux.org/title/User:Allan/Pkgdiff On major version updates, this is approach is a waste of time. But for minor updates bash download would average 25% of the size, coreutils about 36% (though was ~1% for simple rebuilds!), qt5-base about 40% and systemd 60%. Not shown but worth noting note that when Arch changes gcc/binutils versions or updates CFLAGS etc, this can stop any binary diff being as useful. If we implemented using these diffs but only allowed it for updates from the previous package version (i.e. no diffs to package (current - 2) or earlier, or diff chaining), then this would be rather simple to implement (at least from the pacman side...). Any comments before I invest time implementing? Allan
