[pacman-dev] Broken pacman output when resizing
by Constantin Weißer 05 Dec '15

05 Dec '15

Hi there! As probably everyone noticed one time or the other, pacman output (in particular progress bars) breaks whenever one resizes the terminal, which leads to scrambled output like this: https://paste.xinu.at/LNo/plain This is due to the fact, that pacman always claims the whole terminal width. Whenever one runs pacman in tmux (split pane) or uses a tiling wm, resizing happens quite often and will produce such broken output. Considering the output closely, we have quite some "uninteresting" information there. All the 100% progress bars are actually redundant as pacman does not continue installation (or download) if it cannot retrieve a package. Also, it only downloads one package at a time, so we only really care about the progress of the last package (or total progress). I thus propose a different output: https://paste.xinu.at/m-5XEa/ version1 uses a fixed 100 columns output, version2 a fixed 80 columns output. In version1 it is possible to draw the per package progress at the same line as the package name. When complete, only the package name remains. In both versions the currently downloaded package is always the last line of the output. Both proposals contain an example for per package and total progress. I'm personally in favour of version2, because it seems safe to assume that we always have 80 cols available and it also unifies the output style for both per package and total progress. To sum up the changes shown in the mockups, I propose: * progress bars of database synchronising, download and installation move on line below compared with the current output * when a step is complete, the line with the package (or step) name remains, but without any width-dependent progress bars. For download, you find and example in the link above. For installation a finished steop could look like this: (26/63) upgrading opus So basically just the redundant progress bar is removed here. * The output is limited to 80 columns which should fit nicely as seen in the example. * Other output (such as warnings, errors, new optional deps, ...) remains the same. Is there any interest for such a change? If so, I could develop and provide a patch. I'm also happy about comments, fine-tuning and further improvements to the proposal. -- Constantin

[pacman-dev] pacman-5.0 freeze
by Allan McRae 05 Dec '15

05 Dec '15

Hi all, We are calling a freeze on pacman for the upcoming 5.0 release. This means I will only accept bug fixes and patches that have already been submitted (I know there is a few that need reviewed/pushed so I will go through patchwork and look at them all soon). I realise that the festive season is approaching, so I will push strings to Transifex in the next day. This will have the majority of pacman-5.0 changes, but a couple more may slip in. Feel free to ping any patch that has been "ignored"! Allan

[pacman-dev] [PATCH] db_update: always clear db flags after update
by Andrew Gregory 05 Dec '15

05 Dec '15

Signature downloading and DB validation was being based on the most recent download status for the DB. If a DB successfully downloaded but a signature did not, db_update would move to the next server. If the next server tried does not have a more recent copy of the DB, db_update would not download the DB again and would forget that the DB had previously been updated. In this case it would skip validation entirely, leaving an updated DB with the original validation status.

[pacman-dev] System hook dir contains a double slash
by David Macek 29 Nov '15

29 Nov '15

Hi all. In `alpm_initialize`, there's sprintf(hookdir, "%s%s", myhandle->root, SYSHOOKDIR); where `SYSHOOKDIR` is by default `"/usr/share/libalpm/hooks/"` (defined by `-DSYSHOOKDIR=\"@datarootdir@/libalpm/hooks/\"` in `AM_CPPFLAGS`). This means that the resulting `hookdir` is `"//usr/share/libalpm/hooks/"`, or `"/something/else//usr/share/libalpm/hooks/"` if `--root /something/else` is passed on command line. If you need a reason for changing this (other than programmer's tidiness), know that this causes trouble in Cygwin/MSYS2 as paths starting with `//` have special meaning. I can send a patch, but I'm not sure what's the best way to change it. How about sprintf(hookdir, "%s%s", myhandle->root, SYSHOOKDIR + 1); with a corresponding change in the allocation above it and a comment explaining the magic number? It seems that `root` will always end in a slash and `SYSHOOKDIR` will always start with one, so I picked the one easier to remove. -- David Macek

[pacman-dev] [PATCH] Add large file support CFLAGS to pkgconfig file
by Allan McRae 29 Nov '15

29 Nov '15

Large file support is enabled by our configure script as required. If anything linking to libalpm does not also define large file support, there will be differences in the size of off_t which are not caught until runtime. Add the required CFLAGS to the pkg-config file so that users of libalpm know what flags are required. Signed-off-by: Allan McRae <allan(a)archlinux.org> --- Tested with i686-Linux and x86_64-Linux. At worst, on other systems some flags will be missed, making the situation no different than today... configure.ac | 9 +++++++++ lib/libalpm/libalpm.pc.in | 2 +- 2 files changed, 10 insertions(+), 1 deletion(-) diff --git a/configure.ac b/configure.ac index 359d61b..60bb837 100644 --- a/configure.ac +++ b/configure.ac @@ -165,6 +165,15 @@ AC_ARG_ENABLE(git-version, # testing compilation against gpgme).
