2012-08-01util: fix line length calc in _alpm_archive_fgetsDave Reisner1-2/+4
74274b5dc347ba70 which added the real_line_size to the buffer struct didn't properly account for what happens when archive_fgets has to loop more than once to find the end of a line. In most cases, this isn't a problem, but could potentially cause a longer line such as PGP signature to be improperly read. This patch fixes the oversight and focuses on only calculating the line length when we hit the end of line marker. The effective length is then calculated via pointer arithmetic as: (start_of_last_read + read_length) - start_of_line Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-08-01lib/conflict: use a binary search within filelistsDave Reisner1-8/+5
Take advantage of the fact that our filelists are arrays sorted by filename with a known length and use a binary search. This should speed up file conflict checking, particularly when larger packages are involved. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2012-08-01lib/be_local: ensure local filelists are sortedDave Reisner1-0/+2
This may very well be a no-op, but better safe than sorry. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2012-08-01lib/be_package: use qsort instead of our own msortDave Reisner1-49/+3
On the assumption that these arrays are already mostly sorted, use the standard quicksort method to sort the files arrays. The files_msort function name is tweaked to give it a more general name to reflect this change. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

2012-07-10Check empty subdirectory ownershipAllan McRae1-0/+5
When checking if a package owns a directory, it is important to check not only that all the files in the directory are part of the package, but also if the directory is part of a package. This catches empty subdirectories during conflict checking for directory to file/symlink replacements. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2012-07-10Add conflict for replacing owned empty directoryAllan McRae1-6/+26
When two packages own an empty directory, pacman finds no conflict when one of those packages wants to replace the directory with a file or a symlink. When it comes to actually extracting the new file/symlink, pacman sees the directory is still there (we do not remove empty directories if they are owned by a package) and refuses to extract. Detect this potential conflict early and bail. Note that it is a _potential_ conflict and not a guaranteed one as the other package owning the directory could be updated or removed first which would remove the conflict. However, pacman currently can not sort package installation order to ensure this, so this conflict requires manual upgrade ordering.

2012-06-26diskspace: only load filesystem info on demandDave Reisner2-13/+47
Only load filesystem details for the mount points that we're actually going to write to. This reduces our syscall count considerably. In the case of installation, we would actually stat every mountpoint twice (an extra round for download diskspace) which means (on my system) a total of 60 syscalls to write to 3 partitions when installing the kernel package. This change reduces the 60 syscalls down to the expected 3. A slight debug output change is added here to discern between a mountpoint added to our linked list versus when we actually load the fs info.

2012-06-26diskspace: dedupe code for loading FS usageDave Reisner1-25/+27
add mount_point_load_fsinfo() for platforms using getmntent(). Dan: move the #ifdef slightly so we don't have unused functions on certain platforms (e.g., OS X). Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2012-06-26repo-add: add checkdepends informationAllan McRae1-0/+6
Similar to the case for makedepends, it is useful to be able to access this information without parsing a PKGBUILD. Signed-off-by: Allan McRae <allan@archlinux.org>
2012-06-26add line length parameter to _alpm_strip_newlineDave Reisner4-15/+17
If known, callers can pass the line size to this function in order to avoid an strlen call. Otherwise, they simply pass 0 and _alpm_strip_newline will do the call instead. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2012-06-26add real_line_size to alpm_read_bufferDave Reisner2-3/+4
We inevitably call strlen() or similar on the line returned from _alpm_archive_fgets(), so include the line size of the interesting line in the struct. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

2012-06-26diskspace: canonicalize path to download dirDave Reisner1-0/+8
With lazy loading in place, it's now quite obvious that we aren't necessarily checking the right mountpoint for necessary download space. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-05-21fix -Wshadow warnings as reported by gcc 4.4.3Dave Reisner3-20/+20

2012-04-30Convert ALLOC_FAIL macro into a functionDan McGee4-8/+13
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>
2012-04-30be_local: use the right length value for filename in all casesDan McGee1-2/+3
Increment the strlen() provided value by 1 for the NULL byte so we use the right value in all three places we later reference it. Signed-off-by: Dan McGee <dan@archlinux.org>

2012-04-30Move short-lived realpath buffers to the stackDan McGee2-6/+2
There is little reason here to grab 4K from the heap only to return it a few lines later. Instead, just use the stack to hold the returned value saving ourselves the malloc/free cycle. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-04-26libalpm: add pkg-config fileDave Reisner3-0/+16
No one seems to do this "correctly", but for the sake of having an easy method of detecting the presence and version of libalpm on a given system, we provide a straightforward .pc file. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-04-09buildsys: cleanup gpgme compile time checkDave Reisner1-0/+2
- handle gpgme libs and cflags separately rather than appending to CFLAGS and LDFLAGS - be consistent in AC_LINK_IFELSE check for gpgme 1.3.0 (though this is irrelephant since we don't actually run) - be consistent with usage of "have" and "with" variables (this actually ends up reducing SLOC) - when voluntary detection fails, unset GPGME_CFLAGS and GPGME_LIBS - when requested support fails the version check, complain about the min version.

2012-04-07Return more useful error codes on package open failuresDan McGee2-2/+13
Failure isn't always due to the package file location not existing; permission issues can also play a part on something like a FUSE-based filesystem inaccessible to root. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-04-07Make selecting scriptlet shell workAllan McRae1-1/+1
The initial patch to implement this achieved nothing apart from adding a configure option. This patch makes that configure option do what it advertises. Note that specifing any shell apart from /bin/sh causes testsuite failures as /bin/sh is the only shell in the testing environment.

2012-03-16Prefer fputs/fputc over fprintf when writing local databaseDan McGee1-11/+15
Using fputs should be faster as no format string parsing is required. It also prevents silly errors related to unescaped '%' signs, and removes the need to double them up in a lot of places. Signed-off-by: Dan McGee <dan@archlinux.org>

2012-03-16Remove unnecessary path check from local databaseDan McGee1-12/+3
This removes a call to _alpm_local_db_pkgpath() as well as an access() call when reading the local database. This appears to be code from 2006 that has stuck around. We don't need it because: 1) We never use this path except to check it via access(); however, we are already in a readdir() loop so it exists, or at least did at the time of the call. 2) The fopen() and other calls will fail on accessing the database files anyway, and we need to check those for errors.

2012-03-15lib/sync: avoid unwanted unlink after download failDave Reisner1-0/+2
In case we have a mirror failure, unlink_on_fail would remain set, causing an interrupt in a successive download attempt to be wrongly unlinked. This also fixes a memory leak in the url member, as we would allocate over the previous, unfreed URL. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
