* Save backup files with extension .pacsave.nPang Yan Han2013-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Teach pacman to save backup files with extension .pacsave.n, where n is a positive integer. The current backup file shall be saved as <name>.pacsave, while existing .pacsave.n files will be renamed to <name>.pacsave.n+1 Example: 1. You have subversion installed in your local repo. /etc/conf.d/svnserve is a file to be backed up. It contains local modifications 2. You remove subversion from your repo. /etc/conf.d/svnserve is backed up as /etc/conf.d/svnserve.pacsave 2. You install subversion again 3. You edit /etc/conf.d/svnserve 4. You remove subversion. The existing /etc/conf.d/svnserve.pacsave is renamed to /etc/conf.d/svnserve.pacsave.1 and /etc/conf.d/svnserve is backed up as /etc/conf.d/svnserve.pacsave Signed-off-by: Pang Yan Han <pangyanhan@gmail.com> Rebased from original email and adjusted for util-common usage.

* Split common utility functions for libalpm and pacmanAllan McRae2013-01-04
| | | | | | | | | | | | There is duplicated code in the util.c files in the libalpm and pacman source code. Split this into a separate file so that it can be shared via a symlink. This prevents code divergence between the two code bases. Also, move mbasename and mdirname from pacman/util.c into util-common.c in preparation for the following patch that uses them to add an extension to pacsave files.

* Do not warn about missing database if being downloadedAllan McRae2012-12-14
| | | | | | | | | When a configured repo database is not already downloaded, a warning message such as "warning: database file for 'testing' does not exist" is printed. Disable this warning when the database is scheduled to be downloaded in the transaction. Signed-off-by: Allan McRae <allan@archlinux.org>
* Fix future signature timestamp warningAllan McRae2012-12-14
| | | | | | | | | | | | The warning given for a signature timstamp being in the future compared to the system time stated the opposite. Also, move this warning to debug output. It is useless in its current form as the package or database that is giving the error is not mentioned and so other debug output is needed to find the offending signature.

* It turns out we do care about directories...Allan McRae2012-12-14
| | | | | | | | | | 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.

* Avoid upgrade conflict with unchanged effective pathAllan McRae2012-12-14
| | | | | | | | | | | | 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>
* Resolve file paths during inter-package conflict checkAllan McRae2012-12-14
| | | | | | | | 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>

| | | | | | | | 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>
* Detect inter-package conflicts between files and directoriesAllan McRae2012-12-14
| | | | | | | | | | | | 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>

* | util: fix line length calc in _alpm_archive_fgetsDave Reisner2012-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * Check empty subdirectory ownershipAllan McRae2012-07-10
| | | | | | | | | | | | | | | | | | | | | | 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>
| * Add conflict for replacing owned empty directoryAllan McRae2012-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | diskspace: only load filesystem info on demandDave Reisner2012-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
