2012-12-14Detect inter-package conflicts between files and directoriesAllan McRae
Detect a conflict between a file/symlink in one package and a directory in another when both are being installed at once. A side effect is the creation of conflicts between a directory symlink and a real directory (e.g lib -> usr/lib in pkg1 and /lib in pkg2). Given we can not guarantee pkg1 is installed before pkg2, this is a genuine conflict. Signed-off-by: Allan McRae <allan@archlinux.org>

Given the message is repeated for each repo, it is a good idea to print the repo name in the output. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2012-08-02Split _alpm_filelist_operation functionAllan McRae
To improve conflict checking, we will need to make these functions diverge to an extent where having two separate functions will be preferable. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2012-08-02Move filelist functions into separate source fileDan McGee
We have a few of these and might as well gather them together. This also cleans up the code a bit by using an enum instead of integer values, as well as makes a "search for file in filelist" function public so frontends can do better than straight linear search of the filelists.

2012-08-01util: fix line length calc in _alpm_archive_fgetsDave Reisner
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 Reisner
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_package: use qsort instead of our own msortDave Reisner
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 McRae
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 McRae
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.

2012-06-25diskspace: only load filesystem info on demandDave Reisner
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.

2012-06-25diskspace: dedupe code for loading FS usageDave Reisner
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>
2012-06-25repo-add: add checkdepends informationAllan McRae
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>
2012-06-25add line length parameter to _alpm_strip_newlineDave Reisner
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>
2012-06-25add real_line_size to alpm_read_bufferDave Reisner
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>

2012-04-29Convert ALLOC_FAIL macro into a functionDan McGee
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>
2012-04-29be_local: use the right length value for filename in all casesDan McGee

2012-04-08buildsys: cleanup gpgme compile time checkDave Reisner
- 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.
