[pacman-dev] [PATCH] Remove makepath function from frontend
by Laszlo Papp 01 Oct '09

01 Oct '09

Remove makepath function from pacman frontend, because _alpm_makepath(_mode) is good enough from the libalpm API, so it was duplicated in fact, and this function from the API may be paramiterized with permission rights, while makepath from frontend not. It's a cleaning activity too, at last it wasn't used. ./src/pacman/util.c: - this source code contained the makepath() function definition ./src/pacman/util.h: - this header file contained the makepath() function declaration Signed-off-by: Laszlo Papp <djszapi(a)archlinux.us> --- src/pacman/util.c | 36 ------------------------------------ src/pacman/util.h | 1 - 2 files changed, 0 insertions(+), 37 deletions(-) diff --git a/src/pacman/util.c b/src/pacman/util.c index 353aae3..8f6948d 100644 --- a/src/pacman/util.c +++ b/src/pacman/util.c @@ -99,42 +99,6 @@ int getcols(void) return 0; } -/* does the same thing as 'mkdir -p' */ -int makepath(const char *path) -{ - /* A bit of pointer hell here.

[pacman-dev] [PATCH] Signed/unsigned mixup fixup
by Dan McGee 30 Sep '09

30 Sep '09

After our recent screwup with size_t and ssize_t in the download code, I found the `-Wsign-conversion` flag to GCC to see if we were doing anything else boneheaded. I didn't find anything quite as bad, but we did have some goofups- most of our public unsigned methods would return -1 on error, which is a bit odd in an unsigned context.

[pacman-dev] [PATCH 8/8] Replace hardcoded option numbers with enumeration
by Laszlo Papp 25 Sep '09

25 Sep '09

Pacman's long option parsing used hardcoded numbers to identify them. This is not good practice, so replace them with enumeration constants. ./src/pacman/conf.h: - This contains the enumeration of long options that are used in pacman.c source file. ./src/pacman/pacman.c - This source contains long options where the changing was happened. It's safer and more comfortable now, instead of hard coding 10-15 or more integer value into the code.

[pacman-dev] Empty repo databases
by Allan McRae 24 Sep '09

Hi, With the community-testing repo now being empty, I get the following: > pacman -Syu :: Synchronizing package databases... kernel64 is up to date testing 10.3K 21.2K/s 00:00:00 [#####################] 100% core 33.8K 34.8K/s 00:00:01 [#####################] 100% extra 429.2K 13.0K/s 00:00:33 [#####################] 100% error: failed retrieving file 'community-testing.db.tar.gz' from <"mirror"> : Not Found error: failed to update community-testing (Not Found) community 365.3K 10.2K/s 00:00:36 [#####################] 100% :: Starting full system upgrade... local database is up to date Can we leave a shell database somehow when using repo-rm on the last package? It seems [testing] has never been empty! Allan

[pacman-dev] [PATCH] Separate file parsing from backend
by Henning Garus 23 Sep '09

23 Sep '09

Split the huge list of else ifs which was used for parsing 'desc', 'depends', 'files' and 'deltas' files, into separate functions and move them to a new file parse.c . This makes it possible for other backends to share the same parse code. Also change the parsing from the giant else if list to a single loop calling different functions as specified in an array of parser structs (see parse_lines() for details). Move _alpm_delta_parse to parse.c and make it static. Signed-off-by: Henning Garus <henning.garus(a)gmail.com> --- I actually managed to make it longer, instead of shorter (well if you take out comments and license headers this version is roughly as long as the old one), however I think it is more readable. Feel free to call it overkill though. I don't really like the ugets stuff I used to get the next line, but I wanted this to work on something other than FILE*, even though this is not used (yet), and this was the best thing I could come up with. I toyed around with using fopencookie, but that sucks when it comes to portability (there is funopen on bsd, beyond that you are simply screwed). I removed the memset for the line array, it should be fairly safe and I ran valgrind with several pactests and it did not shout at me (at least after I supressed the numerous leaks reported for bash).
