* Make sync DB reading a bit more flexibleDan McGee2011-06-24
| | | | | | | | | | | We can reorganize things a bit to not require reading a directory-only entry first (or at all). This was noticed while working on some pactest improvements, but should be a good step forward anyway. Also make _alpm_splitname() a bit more generic in where it stores the data it parses.

* archive_fgets(): ensure we return any trailing text with no newlineDan McGee2011-06-24
| | | | | | | | | | Discovered this when doing some pactest rewrite work to generate archives in memory only. If a sync database file or PKGINFO file is missing a newline on the final line, the text from that line gets tossed aside and never read into the package struct. This is pretty critical when that last line is a depend or something. Signed-off-by: Dan McGee <dan@archlinux.org>

* Switch all logging to use handle directlyDan McGee2011-06-13
| | | | | | | This is the last user of our global handle object. Once again the diff is large but the functional changes are not. Signed-off-by: Dan McGee <dan@archlinux.org>
* Move pm_errno onto the handleDan McGee2011-06-13
| | | | | | This involves some serious changes and a very messy diff, unfortunately. Signed-off-by: Dan McGee <dan@archlinux.org>
* Require handle argument to all alpm_option_(get|set)_*() methodsDan McGee2011-06-09
| | | | | | | | This requires a lot of line changes, but not many functional changes as more often than not our handle variable is already available in some fashion. Signed-off-by: Dan McGee <dan@archlinux.org>
* Require handle argument to alpm_logaction()Dan McGee2011-06-09
| | | | | | | This is the first in a series of patches to update the API to remove the implicit global handle variable. Signed-off-by: Dan McGee <dan@archlinux.org>
* _alpm_lstat: only duplicate string if necessaryDan McGee2011-06-09
| | | | | | | | | The vast majority of the time we will just be passing the same string value on to the lstat() call. The only time we need to duplicate it is if the path ends in '/'. In one run using a profiler, only 400 of the 200,000 calls (0.2%) required the string to be copied first. Signed-off-by: Dan McGee <dan@archlinux.org>
* Add helper methods for setting directory optionsDan McGee2011-06-07
| | | | | | | This keeps duplicate code to a minimum. This will come in more handy as we refactor some of these option setters away. Signed-off-by: Dan McGee <dan@archlinux.org>
* Use standard errno codes in return from _alpm_archive_fgetsDan McGee2011-06-03
| | | | | | | | | | | | | This allows us to not require the context (e.g. handle) when calling this function. Also beef up the checks in the two callers of this function to bail if the last return code is not ARCHIVE_EOF, which is the expected value. This requires a change to one of the pactest return codes and the overall result of the test, but results in a much safer operating condition whereby invalid database entries will stop the operation.

* Push down extern handle variable to files that need itDan McGee2011-06-03

* Remove ALPM_LOG_FUNC macroDan McGee2011-06-03
| | | | | | | | | The usefulness of this is rather limited due to it not being compiled into production builds. When you do choose to see the output, it is often overwhelming and not helpful. The best bet is to use a debugger and/or well-placed fprintf() statements. Signed-off-by: Dan McGee <dan@archlinux.org>
* Header inclusion cleanupDan McGee2011-04-20
| | | | | | | | This does touch a lot of things, and hopefully doesn't break things on other platforms, but allows us to also clean up a bunch of crud that no longer needs to be there. Signed-off-by: Dan McGee <dan@archlinux.org>
* syntax: if/while statements should have no trailing spaceDan McGee2011-04-20

| * Fix line_offset not being reset in _alpm_archive_fgets()Dan McGee2011-03-21
| | | | | | | | | | | | | | | | | | | | This is a rather serious data corruption issue that luckily manifested itself today in a noticable way. A package in testing had replaces entries read in as ["%RE pkgname", "%RE"] which was clearly wrong. This happens when we hit the end of an archive block, do not have a newline, and have to continue reading from the next block to complete the line. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Style change: return(x) --> return xDan McGee2011-03-20
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was discussed and more or less agreed upon on the mailing list. A huge checkin, but if we just do it and let people adjust the pain will end soon enough. Rebasing should be relatively straighforward for anyone that sees conflicts; just be sure you use the new return style if possible. The following semantic patch was used to do the change, along with some hand-massaging in order to preserve parenthesis where appropriate: The semantic match that finds this problem is as follows, although some hand-massaging was done in order to keep parenthesis where appropriate: (http://coccinelle.lip6.fr/) // <smpl> @@ expression a; @@ - return(a); + return a; // </smpl> A macros_file was also provided with the following content: Additional steps taken, mainly for ASSERT() macros: $ sed -i -e 's#return(NULL)#return NULL#' lib/libalpm/*.c $ sed -i -e 's#return(-1)#return -1#' lib/libalpm/*.c Signed-off-by: Dan McGee <dan@archlinux.org>
* Fix some easy to find double translationsDan McGee2011-02-28
| | | | | | | | A lot of these were places that should have used the same message but didn't, or were very easy to convert to using the same message and letting some of the burden off of the translators. Signed-off-by: Dan McGee <dan@archlinux.org>
* Move locking functions to where they are neededDan McGee2011-02-28
| | | | | | | | We only call these from the transaction init and teardown, so move them to that file, mark them static, and push more of the logic of handle manipulation into these functions. Signed-off-by: Dan McGee <dan@archlinux.org>
* Fix double close of the lock fileJonathan Conder2011-02-27
| | | | | | | | | | According to FOPEN(3), using fclose on an fdopen'd file stream also closes the underlying file descriptor. This happened in _alpm_lckmk (util.c), which meant that when alpm_trans_release closed it again, the log file (which reused the original file descriptor) was closed instead.

* Ensure found files are actually filesDan McGee2011-02-04
| | | | | | | | | We located files in a few places but didn't check if they were files or directories. Ensure they are actually files using stat() and S_ISREG(); this showed itself when trying to download to the directory name itself in FS#22645. Signed-off-by: Dan McGee <dan@archlinux.org>
* Fix locale.h/setlocale inclusion with --disable-nlsDan McGee2011-02-01
| | | | | | | | | Noted in FS#22697. When I factored out _alpm_parsedate() into a common function, I didn't move the <locale.h> include properly, causing a build failure when NLS is disabled and this header isn't automatically included everywhere. Signed-off-by: Dan McGee <dan@archlinux.org>
* 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>

* 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>

* Turn libarchive warnings into libalpm warningsDan McGee2010-12-12
| | | | | | | | | | | | Rather than hiding these warnings, show them to the user as they happen.

* 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.
