[pacman-dev] [PATCH] libmakepkg: when stripping split debug symbols, warn on duplicate paths
by Eli Schwartz 03 Feb '20

03 Feb '20

Trying to strip multiple files installed to the same filepath (in different components of a split package) can produce surprising results if those files are built using different options. Per FS#63356 this is not a supported PKGBUILD configuration. Instead, warn about such cases when producing debug packages.

[pacman-dev] [PATCH] makepkg: make source tarballs work with per-package files containing '$pkgname'
by Eli Schwartz 19 Jan '20

19 Jan '20

Extracting function variables containing arbitrarily scoped variables of arbitrary nature is a disaster, but let's at least cover the common case of using the actual '$pkgname' in an install/changelog file. It's the odd case of actually being basically justified use of disambiguating between the same variable used in multiple different split packages and is even recommended in the PKGBUILD(5) documentation... ... and also, --printsrcinfo already uses and overwrites the variable 'pkgname' in pkgbuild_extract_to_srcinfo, so this "works" in .SRCINFO but doesn't work in .src.tar.gz Fixes FS#64932 Signed-off-by: Eli Schwartz <eschwartz(a)archlinux.org> --- scripts/makepkg.sh.in | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/scripts/makepkg.sh.in b/scripts/makepkg.sh.in index ca3e7459..674e0d87 100644 --- a/scripts/makepkg.sh.in +++ b/scripts/makepkg.sh.in @@ -784,13 +784,14 @@ create_srcpackage() { fi done - local i + local pkgname_backup=(${pkgname[@]}) + local i pkgname for i in 'changelog' 'install'; do local file files [[ ${!i} ]] && files+=("${!i}") - for name in "${pkgname[@]}"; do - if extract_function_variable "package_$name" "$i" 0 file; then + for pkgname in "${pkgname_backup[@]}"; do + if extract_function_variable "package_$pkgname" "$i" 0 file; then files+=("$file") fi done @@ -802,6 +803,7 @@ create_srcpackage() { fi done done + pkgname=(${pkgname_backup[@]}) local fullver=$(get_full_version) local pkg_file="$SRCPKGDEST/${pkgbase}-${fullver}${SRCEXT}" -- 2.24.1

[pacman-dev] [PATCH 1/2] doc: clarify the format of a PKGBUILD source fragment
by Eli Schwartz 25 Dec '19

25 Dec '19

Currently, it could be misread to say that a fragment is literally 'commit', rather than 'commit=somehash'. Anecdotally this does not seem to be obvious to everyone, and rewording it certainly doesn't hurt.

[pacman-dev] Adding an expiry time to repo databases
by Allan McRae 13 Dec '19

13 Dec '19

Hi all, I have made a start at adding an expiry time to repo databases. See the three patches here: https://patchwork.archlinux.org/bundle/Allan/repo_timestamp/ My question is, what should we do once a database is determined to be expired? Follow the example of a bad signature, and refuse to load it at all? Just refuse to install anything from it, but still enable searching etc? Just deciding "bad repo, don't use" will be much easier to implement... Comments? A

[pacman-dev] [PATCH 1/3] libmakepkg: use extraction commands instead of file to find archive type
by Ethan Sommer 11 Dec '19
