2011-10-27Introduce ALPM_BUFFER_SIZE constantDan McGee1-0/+7
This takes the place of three previously used constants: ARCHIVE_DEFAULT_BYTES_PER_BLOCK, BUFFER_SIZE, and CPBUFSIZE. In libarchive 3.0, the first constant will be no more, so we can ensure we are forward-compatible by removing our usage of it now. The rest are unified for consistency. By default, we will use the value of BUFSIZ provided by <stdio.h>, which is 8192 on Linux. If that is undefined, a default value is provided. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-08-29Parse > 2GiB file sizes correctlyDan McGee1-0/+1
We were using atol(), which on 32 bit, cannot handle values greater than 2GiB, which is fail. Switch to a strtoull() wrapper function tailored toward parsing off_t values. This allows parsing of very large positive integer values. off_t is a signed type, but in our usages, we never parse or have a need for negative values, so the function will return -1 on error.

Adjust load_internal() to check the sha256sum value if we have it. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-02Don't trim whitespace when reading database entriesDan McGee1-0/+1
We don't write with extra or unknown whitespace, so there is little reason for us to trim it when reading either. This also fixes the hopefully never encountered "paths that start or end with spaces" issue, for which two pactests have been added. The tests also contain other evil characters that we have encountered before and handle just fine, but it doesn't hurt to ensure we don't break such support in the future.

2011-07-18add _alpm_access() wrapperFlorian Pritz1-0/+1
This is a wrapper function for access() which logs some debug information and eases handling in case of split directory and filename. Signed-off-by: Florian Pritz <bluewind@xinu.at> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-18Handle removal of empty directories properlyDan McGee1-0/+1
This addresses FS#25141. We shouldn't remove every empty directory we come across during the removal process unless it is truly not known to any other package. This will prevent removal of essential directories such as '/var/lock/'. This is accomplished by first checking the empty/non-empty status of a directory, which was previously done implicitly by calling rmdir() and ignoring errors. We do this to avoid the next (new) check in most cases, which is to look at all local packages to see if the to-be-removed directory is present in another packages' filelist. If we do not find it anywhere, then we remove it, else we keep the file around. The pactest has been updated to test more cases, as well as finding a flaw in the original expected to fail case- we need separate DIR and FILE based EXIST rules.

2011-06-24Make sync DB reading a bit more flexibleDan McGee1-1/+2
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. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-20lib/util: call _alpm_log before setting handle->pm_errnoDave Reisner1-2/+4
This is an unfortunate chain of events. RET_ERR and RET_ERR_VOID will eventually call CHECK_HANDLE, which resets the handle's pm_errno member. Dan probably had a reason for doing this, so we merely switch the order of operations in the RET_ERR macros to avoid stomping on our pm_errno. Signed-off-by: Dave Reisner <d@falconindy.com>
2011-06-14Ensure handle is valid and pm_errno is reset when calling into APIDan McGee1-0/+2
We didn't do due diligence before and ensure prior pm_errno values weren't influencing what happened in further ALPM calls. I observed one case of early setup code setting pm_errno to PM_ERR_WRONG_ARGS and that flag persisting the entire time we were calling library code. Add a new CHECK_HANDLE() macro that does two things: 1) ensures the handle variable passed to it is non-NULL and 2) clears any existing pm_errno flag set on the handle. This macro can replace many places we used the ASSERT(handle != NULL, ...) pattern before. Several other other places only need a simple 'set to zero' of the pm_errno field. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-13Switch all logging to use handle directlyDan McGee1-3/+3
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>
2011-06-13Move pm_errno onto the handleDan McGee1-6/+9
This involves some serious changes and a very messy diff, unfortunately. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-09Require handle argument to all alpm_option_(get|set)_*() methodsDan McGee1-2/+2
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>

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>

2011-03-20Style change: return(x) --> return xDan McGee1-1/+1
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>

2011-02-28Move locking functions to where they are neededDan McGee1-2/+0
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>
2011-02-27Fix double close of the lock fileJonathan Conder1-1/+1
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.

2010-12-21Overhaul archive fgets functionDan McGee1-1/+17
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>

2010-10-14Move and rename splitnameAllan McRae1-0/+2
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>

2009-10-11int typing: s/unsigned short/int/ in libalpmDan McGee1-1/+1
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.

2008-02-27libalpm: clean up of md5sum functions.Chantry Xavier1-0/+1
test_delta_md5sum and test_pkg_md5sum were simple wrappers to test_md5sum, and only used once, so not very useful. I removed them. Also, test_md5sum and alpm_pkg_checkmd5sum functions were a bit duplicated, so I refactored them with a new _alpm_test_md5sum function in libalpm/util.c Signed-off-by: Chantry Xavier <shiningxc@gmail.com>

2008-01-11Use dynamic string allocation in package structuresDan McGee1-1/+2
This also affects all structures with static strings, such as depmiss, conflict, etc. This should help a lot with memory usage, and hopefully make things a bit more "idiot proof". Currently our pactest pass/fail rate is identical before and after this patch. This is not to say it is a perfect patch- I have yet to pull valgrind out. However, this should be quite safe to use in all situations from here on out, and we can start plugging the memleaks.
