[pacman-dev] Please make the colourised output exactly like that of "pacman-color"

Hi All, It's great that "pacman" finally has native colour support in v4.1.0. It's just a shame that it's not as good as that of "pacman-color". Without meaning any offence, it falls way short of the mark IMHO. I'm hoping you can just replicate the colourisation of "pacman-color". For your convenience, I've attached the relevant files you'd need. I'm only requesting this because "pacman-color" no longer exists. -- Regards, Xavion.

[pacman-dev] Source Package Repositories
by Allan McRae 06 Dec '15

06 Dec '15

Now we have .SRCINFO in source packages, it would be easy to add the source packages to a repository and have pacman be able to access them. This will kill ABS in Arch! There are two ideas on how this should be handled: 1) Add source package information in the .db file if it is there when a package is added or 2) Have a separate .source repository I have listed the pros/cons of each approach here: https://wiki.archlinux.org/index.php/User:Allan/Pacman_Source_Repositories I personally like #2, because adding them to .db files is a major increase in size. Currently, signatures take up ~55% of the average sync database size. With the source package also having a signature, that increases the db by slightly more than that much again. Any other comments to add to the debate before I make a final decision and implement this? Cheers, Allan

[pacman-dev] [PATCH v2 1/1] libalpm: generate alpm.h on the fly and add version information
by Christian Hesse 28 Nov '15

28 Nov '15

From: Christian Hesse <mail(a)eworm.de> Programs linked against libalpm (for example packagekit) may want to use preprocessor macros to check version and choose correct API.

[pacman-dev] [PATCH 0/4] hooks
by Andrew Gregory 18 Oct '15

18 Oct '15

= TODO = * documentation * run PreTransaction hooks *after* conflict checks * hook/trigger validation * masking hooks with an empty file or symlink to /dev/null * tests = Hook Directories = ALPM handles keep a list of hook directories to scan. Initially, this list is populated with a single directory: /usr/share/alpm/hooks/. This directory is intended for packages to be able to place hooks in a front-end agnostic manner. Front-ends may specify any number of additional directories to search, with later directories overriding earlier ones. Front-ends can disable hooks altogether by setting an empty list. = Parsing Hooks = Configured directories are scanned for files matching '*.hook'. Hook files must be in pacman-style INI format with the following available options: [Trigger] (multiple Trigger sections allowed) Operation = Sync|Remove (Required) Type = File|Package (Required) Target = <Path|PkgName> (Required, multiple allowed) [Action] (only one Action section allowed) When = PreTransaction|PostTransaction (Required) Exec = <Command> (Required) Depends = <PkgName> (Optional) AbortOnFail (Optional, PreTransaction only) Unlike pacman.conf multiple values are *not* allowed on a single line. Exec is currently limited to the path of the executable to run, arguments are not allowed. This is intended to be a temporary limitation until I decide the best way to go about splitting the arguments, which depends in part on whether we want to try to provide hooks with the packages/files that triggered them. Targets are matched the same as IgnorePkg in pacman.conf, meaning multiple targets can be specified and targets can be negated with a leading '!'. If multiple Trigger sections are specified the hook will run if any of them match the transaction. = Running Hooks = Hooks are not cached after running. Directories are rescanned and hooks reloaded each time. This is to make sure that any hooks added/removed during a transaction are appropriately accounted for. Hooks are run exactly the same as install scriptlets (chroot, output passed to the front-end, etc.). They do *not* have access to which package/file triggered the hook. For the time being, run order is officially undefined. apg Andrew Gregory (4): move strtim to util-common move ini parser into common wip add hooks add example hooks hooks/checkboot.hook | 17 +++ hooks/checkmount | 13 ++ hooks/checkmount.conf | 1 + hooks/checkmount.hook | 17 +++ hooks/sync.hook | 16 +++ lib/libalpm/Makefile.am | 2 + lib/libalpm/alpm.c | 1 + lib/libalpm/alpm.h | 10 ++ lib/libalpm/handle.c | 59 ++++++++ lib/libalpm/handle.h | 1 + lib/libalpm/hook.c | 354 +++++++++++++++++++++++++++++++++++++++++++++++ lib/libalpm/hook.h | 34 +++++ lib/libalpm/trans.c | 6 + src/common/ini.c | 116 ++++++++++++++++ src/common/ini.h | 30 ++++ src/common/util-common.c | 39 ++++++ src/common/util-common.h | 2 + src/pacman/ini.c | 117 +--------------- src/pacman/ini.h | 31 +---- src/pacman/util.c | 39 ------ src/pacman/util.h | 1 - src/util/pactree.c | 36 ----- 22 files changed, 720 insertions(+), 222 deletions(-) create mode 100644 hooks/checkboot.hook create mode 100644 hooks/checkmount create mode 100644 hooks/checkmount.conf create mode 100644 hooks/checkmount.hook create mode 100644 hooks/sync.hook create mode 100644 lib/libalpm/hook.c create mode 100644 lib/libalpm/hook.h create mode 100644 src/common/ini.c create mode 100644 src/common/ini.h mode change 100644 => 120000 src/pacman/ini.c mode change 100644 => 120000 src/pacman/ini.h -- 2.4.5

[pacman-dev] pacman files database operations
by Allan McRae 17 Oct '15

17 Oct '15

Hi all, On my "files" branch I have implemented some operations on the .files databases. (remember these are unconditionally created with the repo-add in git now) Download .files databases: $ pacman -Fy :: Synchronizing package databases... ... List files in packages: $ pacman -Fl abs abs /etc/ abs /etc/abs.conf ... Check file ownership using sync databases: $ pacman -Fo /usr/bin/pacman /usr/bin/pacman is owned by pacman 4.2.1-1 Search file lists: $ pacman -Fs libpng.so libpng 1.6.16-1: /usr/lib/libpng.so darktable 1.6.7-1: /usr/lib/darktable/plugins/imageio/format/libpng.so lib32-libpng 1.6.16-1: /usr/lib32/libpng.so Search with regexes: $ pacman -Fsx kcm.*print.*\.so print-manager 15.04.2-1: /usr/lib/qt/plugins/kcm_printer_manager.so kmymoney 4.7.2-1: /usr/lib/kde4/kcm_kmm_printcheck.so Anything else that is worth implementing before I do the much needed rebase on that branch?

[pacman-dev] [PATCH] libmakepkg: check if PKGBUILD variables are arrays or not as appropriate
by Allan McRae 07 Aug '15

07 Aug '15

When extracting variables from PKGBUILD (e.g. for .SRCINFO creation) we make assumptions about whether variables are arrays or not. This adds a check to the PKGBUILD linter to ensure variables are arrays or not as appropriate.

[pacman-dev] Patch-proposal for makepkg: be able to use su for installations even if sudo is installed
by Jonas Große Sundrup 28 Jul '15

28 Jul '15

Hi, at the moment makepkg will use sudo to obtain root privileges if it is installed, otherwise it will use su. This means that if sudo is configured to only allow special commands (and none of those is "pacman"), "makepkg -i" will fail to install the built package. Same goes for installing dependencies with "makepkg -s". The patch appended introduces a new variable into makepkg.conf named SUPER_USER_BINARY, which is set to "sudo" by default. With it being "sudo" makepkg will behave as it does currently, so there should be no breakages with updates. If not set to sudo, makepkg will ignore an installed sudo and use su right away. Comments on this? ~ Jonas >From d4d0e6914ce669123e77f6f470fdbe56e40b449a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jonas=20Gro=C3=9Fe=20Sundrup?= <cherti(a)letopolis.de> Date: Sat, 25 Jul 2015 00:45:18 +0200 Subject: [PATCH] implemented option to use su even if sudo is installed --- etc/makepkg.conf.in | 9 +++++++++ scripts/makepkg.sh.in | 10 ++++++---- 2 files changed, 15 insertions(+), 4 deletions(-) diff --git a/etc/makepkg.conf.in b/etc/makepkg.conf.in index 71ec624..e466edc 100644 --- a/etc/makepkg.conf.in +++ b/etc/makepkg.conf.in @@ -142,4 +142,13 @@ COMPRESSZ=(compress -c -f) PKGEXT='@PKGEXT@' SRCEXT='@SRCEXT@' +######################################################################### +# SUPER USER BINARY +######################################################################### +# +# how to obtain root-privileges for installing packages +# can be either sudo or su +# +SUPER_USER_BINARY='sudo' + # vim: set ft=sh ts=2 sw=2 et: diff --git a/scripts/makepkg.sh.in b/scripts/makepkg.sh.in index 8b6557e..68edee5 100644 --- a/scripts/makepkg.sh.in +++ b/scripts/makepkg.sh.in @@ -229,7 +229,7 @@ run_pacman() { cmd=("$PACMAN_PATH" "$@") fi if [[ $1 != -@(T|Qq) ]]; then - if type -p sudo >/dev/null; then + if type -p sudo >/dev/null && [[ $SUPER_USER_BINARY == "sudo" ]]; then cmd=(sudo "${cmd[@]}") else cmd=(su root -c "$(printf '%q ' "${cmd[@]}")") @@ -1507,9 +1507,11 @@ check_software() { fi # check for sudo if we will need it during makepkg execution - if (( DEP_BIN || RMDEPS || INSTALL )); then - if ! type -p sudo >/dev/null; then - warning "$(gettext "Cannot find the %s binary.

[pacman-dev] Signature within repo databases?
by Allan McRae 22 Jul '15

22 Jul '15

I searched the archives, but I can not find why we stored the package PGP signatures base64'd in the repo database rather than downloading them as needed. Signatures are responsible for ~55% of the Arch repo database size, so I am guessing there must have been a tradeoff. Can anyone provide insight to this? It was 2008... Thanks, Allan
