[RFC][WIP][PATCH 0/5] adding extended package data
by Andrew Gregory 21 Jul '22

21 Jul '22

ALPM is currently parsing several fields that are not particularly relevant to managing package installation (e.g. pkgbase, pkgtype, makedepends, checkdepends). pkgtype in particular is not even exposed in any way through the API, it has to be included in the parser with a "not actually used" comment. This patchset adds an extended data field to packages that can be used by packagers or package-building infrastructure to store arbitrary package data in a way that doesn't require altering alpm for every field and allows the data to actually be retrieved via alpm (though not as easily as first-class fields).

makedepends field of alpm_pkg_t
by Colin Woodbury 16 Jul '22

16 Jul '22

Hi guys, I have a brief question about the `makedepends` field of the `alpm_pkg_t` type. Try as I might, I'm unable to get this field to report anything (i.e. a non-empty alpm_list) for installed packages originally from the AUR that definitely had makedepends. This seems to be the case even when those makedepends are still installed. Under what circumstances should this field be expected to yield results? To be clear, I'm accessing it via the top-level `_pkg_get_makedepends` function. Thanks, Colin

[PATCH] libmakepkg/integrity: handle PGP signature files containing multiple signatures
by Jonas Witschel 26 Jun '22

26 Jun '22

PGP signature files can contain multiple signatures from different keys. In this case, verification is considered to be successful if *all* signatures are valid, compare e.g. the behaviour of the gpgv verification tool. parse_gpg_statusfile() is currently not equipped to handle the gpg output for such signature files: it assumes that the file contains only one signature and therefore overwrites the verification results of previous signatures, effectively only considering the last signature in the file. Therefore the logic needs to be refined so that $success and $trusted are only true if all signatures are valid and trusted, respectively. We also need to store the verification results per key (in order to present more specific error messages) and all the validated fingerprints (in order to check whether they are in validpgpkeys). The signatures for the source tarballs of recent GnuPG releases, e.g. version 2.2.35, are examples of such signature files.

[PATCH] makepkg: Implement the verify function
by Morten Linderud 25 Jun '22

25 Jun '22

From: Morten Linderud <morten(a)linderud.pw> This patch implements a new verify function in makepkg. It allows us to do arbitrary authentication on sources before extraction. There are several new signing and validation methods being implemented and it would be hard to have `makepkg` implement support for things such as sequoia, cosign or minisign. This would allow us to distribute generic validation functions. This also implements a new `copy_` routine for our protocols as we need to have a separation between extracting sources and copying sources.

[Git][pacman/pacman][master] 8 commits: makepkg: use bsdtar --no-read-sparse for archive creation if available

Allan McRae pushed to branch master at Pacman / Pacman Commits: f5f9e0f4 by Jonas Witschel at 2022-03-11T09:43:59+10:00 makepkg: use bsdtar --no-read-sparse for archive creation if available bsdtar uses the "pax" TAR archive format by default, which has support for storing sparse file information in the archive. Unfortunately this is a source of unreproducibility because the sparse encoding is taken from the file system and different file systems handle sparse files differently: some file systems have no support for sparsely encoded files at all, and even file systems with sparse file support can report different file information for identical files due to differing implementations. As a real world example where this happens, consider the Arch Linux package "brotli-testdata 1.0.9-7", which contains a sparsely encoded all-zeros file "usr/share/brotli/testdata/zeros". Building this package on a btrfs file system yields a different package than building it on tmpfs or ext4 solely due to different sparse file information that gets recorded in the package tarball. To improve the reproducibility of archives containing sparsely encoded files, libarchive version 3.6.0 introduces a new --no-read-sparse option. This skips reading sparse file information from disk entirely and therefore stores files "expanded" in the archive, which is the only way to make them reliably reproducible across file systems. makepkg will use this option if libarchive is recent enough to support it, which is detected at build time.

[pacman-dev] [PATCH 1/3] alpm: add ALPM_TRANS_FLAG_NOKEEP
by morganamilo 25 Jun '22

25 Jun '22

this flag prevents backup files from being kept on package installation. This is useful for resetting a package's config files back to their original state. Implements FS#59908 although with it's own flag name instead of reusing nosave. This allows nokeep to optionally create a pacnew that you can then choose to disable by also setting nosave. --- I actually very dislike NOKEEP but it was the best I could come up with I would have prefered overwrite or nosave but they are taken. Better names are welcome. --- lib/libalpm/alpm.h | 3 ++- lib/libalpm/remove.c | 4 +++- 2 files changed, 5 insertions(+), 2 deletions(-) diff --git a/lib/libalpm/alpm.h b/lib/libalpm/alpm.h index 8d8fe243..c6048b63 100644 --- a/lib/libalpm/alpm.h +++ b/lib/libalpm/alpm.h @@ -2704,7 +2704,8 @@ int alpm_pkg_mtree_close(const alpm_pkg_t *pkg, struct archive *archive); typedef enum _alpm_transflag_t { /** Ignore dependency checks. */ ALPM_TRANS_FLAG_NODEPS = 1, - /* (1 << 1) flag can go here */ + /** Don't keep backup files when installing packages. */ + ALPM_TRANS_FLAG_NOKEEP = (1 << 1), /** Delete files even if they are tagged as backup. */ ALPM_TRANS_FLAG_NOSAVE = (1 << 2), /** Ignore version numbers when checking dependencies. */ diff --git a/lib/libalpm/remove.c b/lib/libalpm/remove.c index de39724a..233fff0c 100644 --- a/lib/libalpm/remove.c +++ b/lib/libalpm/remove.c @@ -575,7 +575,9 @@ static int should_skip_file(alpm_handle_t *handle, { return _alpm_fnmatch_patterns(handle->noupgrade, path) == 0 || alpm_list_find_str(handle->trans->skip_remove, path) - || (newpkg && _alpm_needbackup(path, newpkg) + || (!(handle->trans->flags & ALPM_TRANS_FLAG_NOKEEP) + && newpkg + && _alpm_needbackup(path, newpkg) && alpm_filelist_contains(alpm_pkg_get_files(newpkg), path)); } -- 2.33.0
