2010-12-20Only check diskspace availability if needs more than zeroAllan McRae
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).

2010-12-20Always specify arguement type in function delcarationsAllan McRae
Always declare a function with (void) rather than () when we expect no arguements. Fixes all warnings with -Wstrict-prototypes. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-20Use macros in sync DB parsingDan McGee
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>
2010-12-15Add a cushion for diskspace checkingDan McGee
It is the minimum of 5% of disk capacity or 20 MiB on a per-partition basis. Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-14Reorganize fields in package structDan McGee
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 McGee
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>

2010-12-14Add hash_sdbm functionDan McGee
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>

2010-12-12Create sync/ DB directory if it does not existDan McGee
Rather than error out, this is easy enough. Looks quite similar to the code in be_local for creating the local directory. Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-12Merge desc and depends files in local dbAllan McRae
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 McGee
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.

2010-12-12Turn libarchive warnings into libalpm warningsDan McGee
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.

2010-12-12Make reading from any file possible in sync DBDan McGee
Whether it be "desc", "depends", or "deltas", it really doesn't matter- treat them all the same and have the ability to read any data from any file in that list. This continues the work in a44c7b8956. Signed-off-by: Dan McGee <dan@archlinux.org>

2010-12-12Refactor statfs/statvfs type checkDan McGee
Turn it into a configure-type typedef, which allows us to reduce the amount of duplicated code and clean up some #ifdef magic in the code itself.

2010-12-12Add functions to calculate approximate disk usage by packagesAllan McRae
Two helper function are added to calculate the disk usage from packages that are either currently installed on the system or from a package archive. Some minor approximations have been made: 1. Size for directories is not considered when removing a package from the filesystem to avoid multiple counting across packages. Also, these are reported to take zero size while installing. 2. Symlinks are reported to contribute zero size towards removal as libarchive reports them to have zero size for install. 3. Package data files (.PKGINFO, .INSTALL, .CHANGELOG) are counted towards usage on dbpath on install, but their size is not counted on package removal. 4. No handling of extra size needed for .pacsave/.pacnew files. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-12Add function to match file to mount pointAllan McRae

2010-12-12Add function for listing system mount pointsAllan McRae

2010-12-12alpm: don't expose alpm_depcmpXavier Chantry
Either we expose all low levels function dealing with pmdepend_t (splitdep and depfree come to mind), or we don't. Since none of the tools use depcmp, I chose to remove it.

whatprovides and splitdep were removed, so depcmp alone is quite useless now without splitdep, and deptest is not flexible enough.

This patch is only meant for 3.4.x. It prepares the place for the future epoch-aware release. All force packages that get reinstalled or upgraded will get an EPOCH entry in the local database, and thus the new pacman with epoch won't reinstall them by mistake on the first -Su.

2010-12-10Fix possible null pointer deref in check_archDan McGee
If we have a corrupted database, a package can come through without an arch, causing the code to blow up when making strcmp() calls. It might even be possible with perfectly valid database entries lacking an 'arch =' line. This behavior was seen as at least one of the problems in FS#21668.

[Y/n] ( 1/15) removing kde-meta-kdewebdev [------------------------] 100% $ it stopped here.. On one side, libalpm did not initialize the progress bar at 0 percent. So with meta-packages that have 0 files, there was only one progress bar call with percent == 100. On the other side, pacman callback kept track of the last percent that it received. When there are only meta-packages, we always received only 100, so pacman believed the progress bar needed not update. Thus only the first package was actually displayed. A proper fix for the callback would be to keep track of last package name to make sure the recorded prev percent applies. But since we now specify that both Add and Remove should at least send percent=0 at beginning and percent=100 at the end, there is no need for that.
