2010-06-21Clarify testing within conditional statementsAllan McRae
Follow the HACKING guidelines and always use != 0 or == 0 rather than negation within conditional statements to improve clarity. Most of these are !strcmp usages which is the example of what not to do in the HACKING document. Signed-off-by: Allan McRae <allan@archlinux.org>

2010-03-14Only extract new DB entriesXavier Chantry
This implements FS#15198. The idea apparently came from Csaba Henk <csaba-ml <at> creo.hu> which submitted a patch to Frugalware, so thanks to him, even though I did not look at the code :) The idea is to only extract folders for new packages into the package database and clean up the old directories. This is essentially implementing Xyne's "rebase" script within pacman. If using -Syy, just remove and extract everything. If using -Sy : 1. Generate list of directories in DB 2. Generate list of directories in archive 3. Compare both 4. Clean up old directories 5. Extract new directories Original-work-by: Allan McRae <allan@archlinux.org> Signed-off-by: Xavier Chantry <shiningxc@gmail.com> [Dan: fix compile error, s/int/size_t/] Signed-off-by: Dan McGee <dan@archlinux.org>

2009-10-27Fix opendir error condition checksDan McGee
Thanks to Laszlo Papp <djszapi@archlinux.us> for the following catch: opendir(path)) == (DIR *)-1; is maybe the result of misunderstanding the manpage.

2009-10-11cygwin fix : use unsigned char for ctype functionXavier Chantry
See http://www.nabble.com/-PATCH-RFA--Distinguish-between-EOF-and-character-with-value-0xff-td23161772.html#a23188494 cygwin 1.7 actually displays a warning when using signed char with the ctype function, so that compilation fails when using -Wall -Werror.

2009-10-11int typing: s/unsigned short/int/ in libalpmDan McGee
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.

2009-01-20alpm_unpack : change prefix handling to workaround FS#12148.Xavier Chantry
Instead of appending the prefix to each entry name, we can chdir to the prefix before extracting, and restoring when it is done. This seems to work better with the strange and special case of FS#12148 where an archive contained the "./" entry. Signed-off-by: Xavier Chantry <shiningxc@gmail.com>

2009-01-18Use archive_entry_set_perm instead of archive_entry_set_modeNagy Gabor
This patch fixes FS#12148 ('unstable' regular file). I also changed the other archive_entry_set_mode usage in add.c to archive_entry_set_perm. Since I cannot find any relevant info in libarchive manual, I quote Tim Kientzle (the author of libarchive) here, and I say thank you for his help. *** Tim Kientzle wrote ************************************* This is the problem in libalpm/util.c: 323 if(S_ISREG(st->st_mode)) { 324 archive_entry_set_mode(entry, 0644); 325 } else if(S_ISDIR(st->st_mode)) { 326 archive_entry_set_mode(entry, 0755); 327 } Your example unstable.db.tar.gz is not empty. It has one entry in it, called "./". That entry is marked as a directory. But, when you call archive_entry_set_mode(), you are changing the file type! archive_read_extract() then creates the file /var/unstable as you requested. (archive_read_extract() will replace an empty directory with a file.) You should either set the mode value correctly: 323 if(S_ISREG(st->st_mode)) { 324 archive_entry_set_mode(entry, IFREG | 0644); 325 } else if(S_ISDIR(st->st_mode)) { 326 archive_entry_set_mode(entry, IFDIR | 0755); 327 } Or use archive_entry_set_perm(), which does not change the file type: 323 if(S_ISREG(st->st_mode)) { 324 archive_entry_set_perm(entry, 0644); 325 } else if(S_ISDIR(st->st_mode)) { 326 archive_entry_set_perm(entry, 0755); 327 } ************************************************************ Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>

2008-10-12libalpm: handle syscall interruption correctlyDan McGee
It is possible to throw EINTR from a system call such as open(), close(), or waitpid() if custom signal handlers are set up and they are not initialized with the SA_RESTART flag. This was noticed by Andreas Radke when ^C (SIGINT) was given during the call to waitpid(), causing it to throw the EINTR error and we could not accommodate it. Simply wrap these calls in a simple loop that allows us to retry the call if interrupted. Signed-off-by: Dan McGee <dan@archlinux.org>

2008-04-26Completely rework delta algorithmChantry Xavier
Using the graph structures that Nagy set up for dependency sorting, we now do a similar process for deltas. Load up all of the deltas into a graph object on which we can then apply Dijkstra's algorithm, using the new weight field of graph struct. We initialize the nodes weight using the base files that we can use in our filecache (both filename and md5sum must match). The algorithm then picks the best path among those that can be resolved. Note that this algorithm has a few advantages over the old one: 1. It is completely file agnostic. These delta chains do not have to consist of package files- this could be adopted to do delta-fied DBs. 2. It does not use the local_db anymore, or even care if a package or file is currently installed. Instead, it only looks in the filecache for files and packages that match delta chain entries.

2008-01-13util.c : fix segfault when the cachedir isn't usable.Chantry Xavier
For example, if the cachedir is a broken symlink or a non writable directory, pacman fallbacks to /tmp/. Just before doing that, it freed the handle->cachedirs list twice ! once in _alpm_filecache_setup, and once in alpm_option_set_cachedirs. So the first one was removed. Fixes FS#9186. Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
2008-01-05Don't stat cachedir immediatelyDan McGee
By attempting to stat the cachedir when we load the pacman config, pacman bails out if it is a non-existant directory, even if it will never be needed. This is unfortunate as it is only used for sync transactions anyway. Instead, wait until we need it in _alpm_filecache_setup to actually do anything. Reported as FS#9096.
