* Improve splitname memory allocationDan McGee2011-01-21
| | | | | | | | We don't need to create a temporary copy of the string if we are smart with our pointer manipulation and string copying. This saves a bunch of string duplication during database parsing, both local and sync. Signed-off-by: Dan McGee <dan@archlinux.org>
* Add strndup fallback function to libalpm utilDan McGee2011-01-21

* Fix some more simple conversion "errors"Dan McGee2011-01-07
| | | | | | | | None of these warn at the normal "-Wall -Werror" level, but casts do occur that we are fine with. Make them explicit to silence some warnings when using "-Wconversion". Signed-off-by: Dan McGee <dan@archlinux.org>

* Overhaul archive fgets functionDan McGee2010-12-21
| | | | | | | | | | | | | | | | | | | | | | | | The old function was written in a time before we relied on it for nearly every operation. Since then, we have switched to the archive backend and now fast parsing is a big deal. The former function made a per-character call to the libarchive archive_read_data() function, which resulted in some 21 million calls in a typical "load all sync dbs" operation. If we instead do some buffering of our own and read the blocks directly, and then find our newlines from there, we can cut out the multiple layers of overhead and go from archive to parsed data much quicker. Both users of the former function are switched over to the new signature, made easier by the macros now in place in the sync backend parsing code. Performance: for a `pacman -Su` (no upgrades available), _alpm_archive_fgets() goes from being 29% of the total time to 12% The time spent on the libarchive function being called dropped from 24% to 6%. This pushes _alpm_pkg_find back to the title of slowest low-level function. Signed-off-by: Dan McGee <dan@archlinux.org>

* Add hash_sdbm functionDan McGee2010-12-14
| | | | | | | | This is prepping for the addition of a hash field to each package to greatly speed up the string comparisons we frequently do on package name in _alpm_pkg_find. Signed-off-by: Dan McGee <dan@archlinux.org>
* Turn libarchive warnings into libalpm warningsDan McGee2010-12-12
| | | | | | | | | | | | Rather than hiding these warnings, show them to the user as they happen. This will prevent things such as hiding full filesystem errors (ENOSPC) from the user as seen in FS#11639.

* Move and rename splitnameAllan McRae2010-10-14
| | | | | | | | | The splitname function is a general utility function and so is better suited to util.h. Rename it to _alpm_splitname to indicate it is an internal libalpm function as was the case prior to splitting local and sync db handling. Signed-off-by: Allan McRae <allan@archlinux.org>
* Use OpenSSL MD5 crypto functions if availableDan McGee2010-09-02
| | | | | | | | | | | | | | | I've noticed my Atom-powered laptop is dog-slow when doing integrity checks on packages, and it turns out our MD5 implementation isn't near as good as that provided by OpenSSL. Using their routines instead provided anywhere from a 1.4x up to a 1.8x performance benefit over our built-in MD5 function. This does not remove the MD5 code from our codebase, but it does enable linking against OpenSSL to get their much faster implementation if it is available on whatever platform you are using. At configure-time, we will default to using it if it is available, but this can be easily changed by using the `--with-openssl` or `--without-openssl` arguments to configure.

* Only extract new DB entriesXavier Chantry2010-03-14
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | Thanks to Laszlo Papp <djszapi@archlinux.us> for the following catch: opendir(path)) == (DIR *)-1; is maybe the result of misunderstanding the manpage.

| | | | | | | | | | | | | | | | | | | | 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.

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>

* libalpm: handle syscall interruption correctlyDan McGee2008-10-12
| | | | | | | | | | | | | 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>

* Completely rework delta algorithmChantry Xavier2008-04-26
| | | | | | | | | | | | | | | | | | | | 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.
