2018-07-27Handle root prefix in overwrite operationsAllan McRae1-4/+5
The pacman --overwrite operation currently expects a path without the root prefix specified. This is unexpected, particularly given our conflict error message reports the path with the root prefix included. This patch allows libalpm to overwrite files with the root prefix specified.

2018-05-14Remove all modelines from the projectEli Schwartz1-2/+0
Many of these are pointless (e.g. there is no need to explicitly turn on spellchecking and language dictionaries for the manpages by default). The only useful modelines are the ones enforcing the project coding standards for indentation style (and "maybe" filetype/syntax, but everything except the asciidoc manpages and makepkg.conf is already autodetected), and indent style can be applied more easily with .editorconfig Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>

Allows for safer, more fine-grained control for overwriting files than --force's all-or-nothing approach. Implements FS#31549. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2017-01-04conflict: skip dir children when replacing a fileAndrew Gregory1-1/+15
When replacing a file with a directory, any files under that directory do not need to be checked for conflicts. This prevents possible false-positive conflicts where the file being replaced is a symlink. We were already skipping the directory children when the file was owned by the previous version of a package being upgraded. This extends that to other packages being removed.

2015-12-05skip conflicts resolved by file replacementAndrew Gregory1-0/+15
When replacing a file with a directory, any files inside the new directory cannot possibly exist on the filesystem and can be skipped. This allows cross-package symlink-to-directory transitions when there are files with the same name under both the symlinked directory and the new directory.

Forcing vim users to view files with a tabstop of 2 seems really unnecessary when noet is set. I find it much easier to read code with ts=4 and I dislike having to override the modeline by hand.

2013-06-03improve dir->file transition conflict resolutionAndrew Gregory1-68/+65
Packages removed due to conflicts are always removed at the beginning of the transaction and as such can be included in the check for whether all owners of a directory will be removed in a transaction. Installed versions of packages being upgraded, other than the one with the conflict, cannot be used because our transaction ordering is not intelligent enough to ensure that they are removed prior to the installation of the conflicted package. Also, return false from dir_belongsto_pkgs on errors. Previously, we simply continued which could return true even if we were unable to actually establish that the package owned the entire tree.

2013-06-03conflict.c: exclude trailing slash from file pathAndrew Gregory1-6/+6
After the initial checks, we either use the path as a directory and have to append the trailing slash anyway or use it as a file in which case the trailing slash should be excluded. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2013-05-04conflict.c: compare package pointers directlyAndrew Gregory1-3/+5
p1 and p2 both come directly from the upgrade list without being copied so they can be compared directly instead of comparing their names. Also fix minor style violation. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2013-02-24Perform limited conflict checking with --forceAllan McRae1-2/+26
Pacman currently bails when trying to extract a file over a directory when using --force. Instead of ignoring all conflict, perform the check and skip any file-file conflicts. Conflicts between directories and files are still flagged and cause the transation to abort. As a bonus, we now know about files changing packages when using --force, so we can skip removing them fixing upgrade046. Signed-off-by: Allan McRae <allan@archlinux.org>
2013-02-24use resolved_path for filelist_containsAndrew Gregory1-0/+5
alpm_filelist_contains was being used to search for resolved paths, but searching in the unresolved paths, causing it to miss matches. We always search unresolved paths and search the resolved paths if available because _alpm_filelist_resolve is not public and requires a context handle, so it can't be called from alpm_filelist_contains.

2013-02-24return resolved paths from filelist_differenceAndrew Gregory1-22/+14
We were comparing files based on resolved paths but returning the original file_t structures, which were not necessarily in the same order. The extra file_t information was only being used to determine if the file was a directory which can be accomplished by testing for a trailing slash, so just return the resolved path.

2013-02-24return resolved paths from filelist_intersectionAndrew Gregory1-2/+2
We were comparing files based on resolved paths but returning the original file_t structures, which were not necessarily in the same order.

2012-12-14Avoid upgrade conflict with unchanged effective pathAllan McRae1-0/+1
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 McRae1-0/+5
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>
2012-08-02Split _alpm_filelist_operation functionAllan McRae1-6/+6

2012-08-02Move filelist functions into separate source fileDan McGee1-86/+11
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.

2012-07-10Check 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>
