2012-04-30Convert ALLOC_FAIL macro into a functionDan McGee1-5/+5
This path is rarely (read: never) taken in any normal run of the code, so injecting the fprintf() call everywhere with the macro is a bit overkill. Instead, add a lightweight _alpm_alloc_fail() function that gets called instead. This does have a reasonable effect on the size of the generated code; most places using the macros provided by util.c have their code size reduced. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-04-09Various tweaks to support building with excessive GCC warning flagsDan McGee1-1/+1
This fixes a bunch of small issues in order to enable a clean successful build with a crazy number of GCC warning flags. A lot of these changes are covered by -Wshadow, -Wformat-security, and -Wstrict-overflow=5. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-03-09Remove _alpm_csumAllan McRae1-6/+1
The enum alpm_pkgvalidation_t is essentially a more generic version of _alpm_csum, so use it instead. Signed-off-by: Allan McRae <allan@archlinux.org>
2012-02-20Update copyright yearsAllan McRae1-1/+1
Add 2012 to the copyright range for all libalpm and pacman source files. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2012-01-23Remove rmrf implementation from backendDan McGee1-1/+1
This moves the code for removal of local database entries right into be_local.c, which was the last user of the rmrf() function we had in our utility source file. We can simplify the implementation and make it non-recursive as we know the structure of the local database entries. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-12-23Remove strtrim function from backendDan McGee1-1/+0
The last user of this was the code in the backend for loading packages, but this no longer uses it. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-12-22include config.h via MakefilesDave Reisner1-2/+0
Ensures that config.h is always ordered correctly (first) in the includes. Also means that new source files get this for free without having to remember to add it. We opt for -imacros over -include as its more portable, and the added constraint by -imacros doesn't bother us for config.h. This also touches the HACKING file to remove the explicit mention of config.h as part of the includes.

2011-11-22added doxygen documentationandrew.gregory.8@gmail.com1-1/+1
Made existing documentation more consistent and added documentation where there was none. One function still needs documentation and is marked with 'TODO'. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-11-16Add helper method for creating and opening archive objectDan McGee1-0/+3
This moves the common setup code of about 5 different callers into one method. Error messages will now be common and shared in all places; several paths did not have any messages at all before. In addition, we now pick an ideal block size for the archive read based off the larger value of our default buffer size or the st.st_blksize field. For a filesystem such as NFS, this is often much larger than the default 8192- values such as 32768 and 131072 are common. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-11-13add support for back end fnmatch'd optionsDave Reisner1-0/+1
This is work originally provided by Sascha Kruse on FS#20360 with only minor adjustments to the implementation. It's been expanded to cover: NoUpgrade, NoExtract, IgnorePkg, IgnoreGroup. Adds tests ignore008, sync139, sync502, and sync503. Also satisfies FS#18988. Original-work-by: Sascha Kruse <knopwob@googlemail.com> Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2011-11-01Add OPEN() and CLOSE() util macrosDan McGee1-1/+11
These wrap the normal open() and close() low-level I/O calls and ensure EINTR is handled correctly. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-11-01Merge branch 'maint'Dan McGee1-0/+7
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>
2011-10-12Convert MALLOC to actually call malloc()Dan McGee1-1/+1
If you need zero-filled allocations, call CALLOC() instead. This was from the original definition of these macros in commit cc754bc6e3be0f3; hopefully our code is in the shape it needs to be to switch this behavior. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-10-12Introduce alpm_time_t typeDan McGee1-2/+1
This will always be a 64-bit signed integer rather than the variable length time_t type. Dates beyond 2038 should be fully supported in the library; the frontend still lags behind because 32-bit platforms provide no localtime64() or equivalent function to convert from an epoch value to a broken down time structure. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-01_alpm_parsedate(): return time_t and not longDan McGee1-1/+1
Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-30Parse > 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.

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>
2011-06-14Switch 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>
2011-06-14Move 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>

2011-03-21Style 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>

2011-02-27Fix 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>
