2017-04-17conflict: include owner for filesystem conflictsAndrew Gregory2-0/+18
Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
2017-04-17unlink_file: strip trailing slashesAndrew Gregory2-0/+17
If the user replaces a directory with a symlink, libalpm would get confused because the trailing slash causes system calls to resolve the symlink. This leads to errors and a misleading message during upgrades. Even though libalpm does not support this, it should not be giving misleading errors. Also adds an overflow check. Fixes FS#51377 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
2017-04-12add --overwrite option to ignore file conflictsAndrew Gregory4-0/+42
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 Gregory2-0/+19
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.

2017-01-04extract db files with dbonlyAndrew Gregory2-0/+17
Some database files (install, mtree, and changelog) are extracted directly from the package, but DBONLY was skipping extraction altogether, causing those files to be missing after the transaction.

2016-08-30recursedeps: include cyclic dependenciesAndrew Gregory2-0/+42
Cyclic dependencies (A depends on B, B depends on A) were not selected because neither package could be removed individually, so can_remove_package would always return false for both. By preselecting all dependencies then filtering back out any dependencies still required by any packages that will not be uninstalled, groups of unneeded cyclic dependencies can be found.

2016-05-05Print replacements when using -SupAllan McRae2-0/+15
When printing a list of URLs of packages to be updated, pacman was ignoring any replacements that would be made in the update process. Fixes FS#35812 Signed-off-by: Allan McRae <allan@archlinux.org>
2016-02-23do not rely on localdb for hook matchingAndrew Gregory2-0/+24
Relying on localdb to determine which trigger operations should match is completely broken for PostTransaction hooks because the localdb has already been updated. Store a copy of the old version of any packages being updated to use instead.

Check if we overwrote an exiting pacnew file before unlinking it. Otherwise, updating to a version with an unchanged file would delete existing pacnew files. FS#47993 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2016-01-15test version range restrictions corner caseDominik Fischer2-0/+20
The test introduced herein illustrates a behavior that may be unexpected to package writers. It creates a package "pkg3" that is configured to depend on a "dependency" which version is between 3 and 4, inclusive. Two other packages are already present, providing "dependency" in version 2 and 5, respectively. So, the situation looks roughly like this: pkg1 pkg3 pkg2 provides depends on provides | <------------> | version __________2____________3____________4____________5___________... This seems to be enough to satisfy pacman when installing "pkg3". From an iterative standpoint, this is completely logical: First, the requirement "dependency>=3" is checked. There is a package that satisfies this restriction, it is called "pkg2". Afterwards, "dependency<=4" is covered in the same way by "pkg1". Nonetheless, what a package writer intends when specifying depends=('dependency>=3' 'dependency<=4') is most probably that pacman should only allow this package to be installed when there indeed is a package present that provides a version of "dependency" that lies _between_ 3 and 5.

2015-12-05skip conflicts resolved by file replacementAndrew Gregory1-2/+0
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.

2015-12-05Detect potential conflict when symlink to directory is changing to directoryAllan McRae2-0/+29
When a symlink to a directory is changing to a directory, any package file inside the new directory can create an unexpected conflict with the filesystem. Reported by Neofytos and Luca from Chakra. Signed-off-by: Allan McRae <allan@archlinux.org>

2015-02-12sync200.py.in: remove unused substitutionAndrew Gregory3-22/+2
LIBCURL was never set in the Makefile so XferCommand was always being set in the test file.

2014-08-03add test for file type check with -QkAndrew Gregory2-0/+15
If a directory has been replaced by a symlink, -Qk currently stats the symlink target rather than the symlink itself and doesn't check that the actual file type matches the package file list. This will make it difficult to discover errors once 4.2 is released and replacing directories with symlinks is no longer supported. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>

2014-01-06Add the unit tests for -Qk and -Qkk that are possible now.Jeremy Heiner3-0/+32
The -Qk test (001) validates the existence of the package files (which were installed to the filesystem by the framework because the package was added to the "local" db). The -Qkk test (002) does not validate any file's properties - it can only check that the pacman run produces the expected warning message saying that the package lacks an mtree. Further tests will require modifications to the testing framework to allow intentional damage to the filesystem and generating an mtree.

2013-10-31pacman -Si/-Qi: Autodetect best fitting file size unitFlorian Pritz1-1/+1
I've tracked this back to e223366 and it looks like this just forces KiB because back then humanize_size didn't exist, but the size was just divided by 1024 to keep it somewhat readable. When humanize_size got introduced in 3c8a448 this was just carried over. The unit detected for "Download Size" is reused for "Installed Size" to make it easier to read.

2013-10-31sortbydeps: include local pkgs in dep graphAndrew Gregory1-0/+2
Detecting indirect dependencies by traversing a package's entire dependency tree is prohibitively slow for larger transactions. Instead add local packages to the dependency graph. This additionally requires delaying dependency ordering for sync operations so that removed packages may be excluded from dependency detection. tests/sync012.py was also updated to ensure that the dependency cycle was actually detected.

2013-10-14Use Python's "range" instead of deprecated "xrange".Jeremy Heiner3-5/+5
Reported by 2to3. Python 3 throws out the old range, renames the old xrange to be the new range, leaving no xrange. A shim could be used, but using the less efficient version does not have a noticeable impact on the run time. This observed (lack of an) effect is as described in the Python 2 docs for xrange. The largest range created is only 1000 elements big, and the memory cost of those ranges is negligible when compared to that of all the pmpkg instances created.

2013-06-26deps.c: check for indirect deps when orderingAndrew Gregory2-2/+44
On upgrades, indirect dependencies were not being detected if there was a dependency in between them that was not part of the transaction. For example, with the dependency chain: pkg1 -> pkg2 -> pkg3, if pkg1 and pkg3 are being upgraded but not pkg2 pacman would not order pkg1 and pkg3 properly. This was particularly problematic when replacements were involved because the replaced package(s) would be removed at the start of the transaction. If an install script required the replacer and lacked a direct dependency, it could fail. Fixes FS#32764. Partially fixes FS#23011.

2013-06-03improve dir->file transition conflict resolutionAndrew Gregory1-0/+17
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.
