2010-12-30Declare all local functions staticAllan McRae7-63/+67
All functions that are limited to the local translation unit are declared static. This exposed that the _pkg_get_deltas declaration in be_local.c was being satified by the function in packages.c which when declared static caused linker failures. Fixes all warnings with -Wmissing-{declarations,prototypes}. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

2010-12-29makepkg: add option to clear buildflagsAllan McRae3-2/+15
Add the "buildflags" option, which is useful in its negative form for disabling CFLAGS, CXXFLAGS and LDFLAGS when building a package. This is useful when determining of one of these flags is causing an issue with a package. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-29makepkg: Add check() function for running test suitesAllan McRae7-8/+70
A PKGBUILD can have an option check() function for running test suites between the build() and package() stages. This function is run by default but can be disabled globally in with "!check" in BUILDENV in makepkg.conf. This setting can be controlled on an individual package basis using makepkg's --check and --nocheck flags. Addition dependencies needed for running the test suite can be specified in the checkdepends array and are only checked when running the check() function.

2010-12-29Use limits.h for PATH_MAXAllan McRae3-10/+6
We use PATH_MAX everywhere by including limits.h so there is no point in doing a check for it in a different header when dealing with FreeBSD's libfetch. Also, remove autoconf check for strings.h header as it is not used anywhere. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-29Detect undefined PATH_MAXAllan McRae11-5/+25
POSIX does not require PATH_MAX be defined when there is not actual limit to its value. This affects HURD based systems. Work around this by defining PATH_MAX to 4096 (as on Linux) when this is not defined. Also, clean up inclusions of limits.h and remove autoconf check for this header as we do not use macro shields for its inclusion anyway.

2010-12-29makepkg: escape closing bash array paren for awkDave Reisner1-4/+4
The closing parenthesis of bash arrays needs to be escaped in the ending address of awk expressions in order to play nicely with implementations of awk other than gawk. This change provides compatibility with gawk, nawk and mawk.

2010-12-29makepkg: allow pkgname usage in split package functionsAllan McRae1-4/+6
Currently, using $pkgname in a split package package_*() function always returns the first value in the pkgname array rather than the name of tha package being packaged. Fix this so $pkgname gives the expected value. Fixes FS#22174 Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

2010-12-21Use name hashes in depends to avoid strcmp callsDan McGee2-8/+18
Just like we did for package name comparsions, if we add a depend name_hash field on depend struct initialization, we can use it instead of doing a string name comparison, saving us a lot of checks in the depcmp code. Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-21Remove need for memory allocation in _alpm_depcmpDan McGee1-9/+13
Noticed when tweaking testdb, when we run _alpm_depcmp in loops and call it seven million times, the strdup()/free() combo can add up. Remove the need for any string duplication by some pointer manipulation and use of strncmp instead of strcmp. Also kill the function logger and add an escape so we don't needlessly retrieve the list of provides. Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-21Add pactest to test long archive readsDan McGee1-0/+19
This creates two packages with extremely long description lines (500KB and 600 KB), causing our archive read code to perform reallocation to store the whole contents. One of the packages will successfully read while the other will fail for the time being. Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-21pactest: allow testing of package descriptionDan McGee2-10/+7

2010-12-21Overhaul archive fgets functionDan McGee4-32/+114
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>
2010-12-20testdb: update for new database formatDan McGee1-33/+21
Sync DB's no longer have an extracted directory, so remove the files check for those. Local databases no longer have a 'depends' file, so kill that check as well. Finally, do a little other cleanup and remove the need for PATH_MAX. Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-20Only check diskspace availability if needs more than zeroAllan McRae1-1/+2
The amount of diskspace needed for a transaction can be less than zero. Only test this against the available disk space if it is positive, which avoids a comparison being made between signed and unsigned types (-Wsign-compare).

2010-12-20makepkg: remove last inappropriate PKGBUILD usageAllan McRae1-1/+1

2010-12-20Use macros in sync DB parsingDan McGee1-99/+52
This simplifies a lot of the repetative code and makes it obvious where the tricky or different ones are (e.g. depends, dates). It also makes it significantly easier to change the way this code works in the future. There should be no functional change with this patch. Signed-off-by: Dan McGee <dan@archlinux.org>

2010-12-14Reorganize fields in package structDan McGee1-13/+15
Saves a few bytes due to padding (256 -> 248 bytes), especially on x86_64, so we get the overhead of our new hash field right back. Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-14Used hashed package name in _alpm_pkg_findDan McGee1-2/+13
This results in huge gains to a lot of our codepaths since this is the most frequent method of random access to packages in a list. The gains are seen in both profiling and real life. $ pacman -Sii zvbi real: 0.41 sec -> 0.32 sec strcmp: 16,669,760 calls -> 473,942 calls _alpm_pkg_find: 52.73% -> 26.31% of time $ pacman -Su (no upgrades found) real: 0.40 sec -> 0.50 sec strcmp: 19,497,226 calls -> 524,097 calls _alpm_pkg_find: 52.36% -> 26.15% of time There is some minor risk with this patch, but most of it should be avoided by falling back to strcmp() if we encounter a package with a '0' hash value (which we should not via any existing code path). We also do a strcmp once hash values match to ensure against hash collisions. The risk left is that a package name is modified once it was originally set, but the hash value is left alone. That would probably result in a lot of other problems anyway. Signed-off-by: Dan McGee <dan@archlinux.org>

2010-12-12Merge desc and depends files in local dbAllan McRae3-94/+61
Whenever depends is needed from the local db, so is desc. The only disadvantage to merging them is the additional time taken to read the depends entries when they are not needed. As depends is in general relatively small, the additional time taken to read it in will be negligable. Also, merging these files will speed up local database access due to less file seeks.

2010-12-12Attempt to stop installation when we encounter problemsDan McGee1-32/+48
This should hopefully address some of the concerns raised in FS#11639 with regards to continuing after filling the disk up. Add some more checks and passing of error conditions between our functions. When a libarchive warning is encountered, check if it is due to lack of disk space and if so upgrade it to an error condition. A review of other libarchive warnings suggests that these are less critical and can remain as informative warning messages at this stage. Note the presence of errors after extraction of an entire package is complete. If so, we abort the transaction to be on the safe side and keep damage to a minimum.
