2010-12-30Merge branch 'fgets-perf'Dan McGee7-42/+140
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
And modify the code to not print the full rule string if it is more than 40 characters long; truncate it instead. Signed-off-by: Dan McGee <dan@archlinux.org>
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>
2010-12-21testdb: 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>
2010-12-21Only 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).

2010-12-21Always specify arguement type in function delcarationsAllan McRae6-28/+28
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>
2010-12-21makepkg: remove last inappropriate PKGBUILD usageAllan McRae1-1/+1
We should always use $BUILDSCRIPT instead of PKGBUILD. The only remaining uses of PKGBUILD in makekg are in comments. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-21Use 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>
2010-12-15Merge branch 'maint'Dan McGee3-20/+25
2010-12-15Add a cushion for diskspace checkingDan McGee1-3/+8
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>
2010-12-15Document PKGEXT and SRCEXTAllan McRae1-2/+3
Add some basic documentation for the PKGEXT and SRCEXT options in makepkg.conf. Fixes FS#21302. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-15Reorganize 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>

2010-12-14Add hash_sdbm functionDan McGee2-0/+22
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>

2010-12-13Add script to update pacman database formatAllan McRae2-0/+124
The pacman-db-upgrade script was added to detect old pacman database formats and upgrade them. Currently performs the merging of depends files into desc files in the local database. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

2010-12-13Merge 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.

2010-12-13Attempt 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.

2010-12-13Turn libarchive warnings into libalpm warningsDan McGee2-3/+3
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.

2010-12-13Make reading from any file possible in sync DBDan McGee1-12/+8
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>
2010-12-13Explicitly test time difference is greater than zeroAllan McRae1-1/+1

2010-12-13Refactor statfs/statvfs type checkDan McGee4-62/+50
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. Adjust some of the other defined checks to look at the headers available rather than trying to pull in the right ones based on configure checks.

2010-12-13Add functions to calculate approximate disk usage by packagesAllan McRae2-0/+103
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>
2010-12-13Add function to match file to mount pointAllan McRae1-0/+28
For a given file, determine which mount point it is on or will be installed to. Take into account that we might be using an alternative installation root. Add additional helper function added to sort mount point list for easier matching. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-13Add function for listing system mount pointsAllan McRae3-1/+160
