2012-12-14It turns out we do care about directories...Allan McRae1-19/+9
This is a bug that has been around since at least 2007. On a package upgrade (either by -S or -U) a new directory could overwrite any file. This is caused by the filelist difference calculation ignoring all directories and thus no new directories were checked for conflicting files on the filesystem.

2012-12-14_alpm_filelist_resolve: add useful return codeAndrew Gregory2-38/+47
Return -1 if a path is too long to resolve or we run out of memory. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2012-12-14Avoid upgrade conflict with unchanged effective pathAllan McRae2-3/+3
This applies to a case such as when /lib is a symlink to /usr/lib. If a package is installed which contains /lib/libfoo.so, pacman will complain if this package is then "fixed" to contain /usr/lib/libfoo.so. Since these have the same effective path and it exists within the same package, ignore the conflict. Fixes FS#30681. Signed-off-by: Allan McRae <allan@archlinux.org>
2012-12-14Resolve file paths during inter-package conflict checkAllan McRae2-8/+10
File paths are resolved if necessary during inter-package conflict checks so that packages carrying the same effective file due to directory symlinks on the filesystem are flagged as conflicting. Signed-off-by: Allan McRae <allan@archlinux.org>
2012-12-14_alpm_filelist_resolve: use original filenames where possibleAndrew Gregory2-22/+34

2012-12-14Add _alpm_filelist_resolveAndrew Gregory2-0/+181
The _alpm_filelist_resolve function takes a filelist and creates a list with any symlinks in directory paths resolved. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2012-12-14Add resolved_path to alpm_filelist_tAllan McRae2-1/+11
Add an array to hold the resolved paths of the files in alpm_filelist_t. When the file name and its resolved file name are identical, the pointer to the original file name is used to avoid duplicate memory allocation. Signed-off-by: Allan McRae <allan@archlinux.org>
2012-12-14Detect inter-package conflicts between files and directoriesAllan McRae1-13/+38
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>

2012-08-02Split _alpm_filelist_operation functionAllan McRae3-30/+57
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 McGee11-104/+178
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 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_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

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>

2012-04-30Convert 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>
