2014-01-06Use O_CLOEXEC as much as possible when opening filesDan McGee4-11/+18
When calling open(), use O_CLOEXEC as much as possible to ensure the file descriptor is closed when and if a process using libalpm forks. For most of these cases, and especially in utility functions, the file descriptor is opened and closed in the same function, so we don't have too much to worry about. However, for things like the log file and database lock file, we should ensure descriptors aren't left hanging around for children to touch. This patch is inspired by the problem in FS#36161, where an open file descriptor to the current working directory prevents chroot() from working on FreeBSD. We don't need this file descriptor in the child process, so open it (and now several others) with O_CLOEXEC.

2014-01-06deps.c: remove filtered_depend functionsAndrew Gregory1-22/+10
filtered_dep was duplicating an alpm_depend_t solely for the purpose of overriding its depmod and would effectively cause alpm_checkdeps to ignore ALPM_TRANS_FLAG_NODEPVERSION if the duplication failed. Manually overriding/restoring the depmod for the original depend removes the duplication as a point of failure and fixes a memory leak where the duplicated depend was not being properly freed.

2013-12-15Close file descirptor before forkWolfgang Bumiller1-0/+1
FreeBSD chroot(2) fails with EPERM when a directory file descriptor is open with either `kern.chroot_allow_open_directories` being 0, or when the process already is inside a chroot. This is exposed in alpm_run_chroot that uses opendir() to open a file descriptor to the current directory before doing the forking and chrooting. Since the file descriptor is not used in the forked process, we close it. Fixes FS#36161. Signed-off-by: Allan McRae <allan@archlinux.org>

This ensures that important events will be logged and consistent regardless of the frontend. The need for global context in the event callback is also removed. The event is logged before any post_* scripts run, so this also moves the post_* script output underneath the event in the log.

There was a brief window between opening the file descriptor and creating a stream to it. If the process was interrupted during that window the lock file would not be removed correctly.

2013-10-31sortbydeps: include local pkgs in dep graphAndrew Gregory4-89/+80
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.

2013-10-15Ensure packages have a valid versionAllan McRae1-0/+4
Currently you can manually create and then install a package with a version not containing a pkgrel. The created local database entry is invalid as the directory name can not be split by _alpm_splitname due to the assumtion of hyphens separating name-pkgver-pkgrel.

2013-10-15Fix progress bar overflow while checking package integrityAllan McRae1-3/+5
On 32bit systems, the progress bar intergrity checking can show values greater than 100% with large transactions. This is due to the total size of all package files being greater than a size_t. Use uint64_t for these sizes. Fixes FS#36608 Signed-off-by: Allan McRae <allan@archlinux.org>

2013-09-18dload: avoid renaming files downloaded via sync operationsChristian Hesse2-17/+22
If the server redirects from ${repo}.db to ${repo}.db.tar.gz pacman gets this wrong: It saves to new filename and fails when accessing ${repo}.db. We need the remote filename only when downloading remote files with pacman's -U operation. This introduces a new field 'trust_remote_name' to payload. If set pacman downloads to the filename given by the server. The field trust_remote_name is set in alpm_fetch_pkgurl(). Fixes FS#36791 ([pacman] downloads to wrong filename with redirect).

We currently only warn if a directory's permissions differ, but using -Qkk on my system shows that directory permissions tend to change in packages reasonably frequently without notice.

2013-07-22be_sync: avoid crashing on files in the root of a DBDave Reisner1-0/+8
If a sync DB is malformed and contains entries in the root of the archive, load_pkg_for_entry will leave the 'filename' variable empty, leading to a crash in the ensuing strcmp() calls which determine the DB fragment being examined.

2013-07-05do not check error from close(2)Dave Reisner6-25/+24
On operating systems we support, the behavior is always such that the kernel will do the right thing as far as invalidating the file descriptor, regardless of the eventual return value. Therefore, potentially looping and calling close multiple times is wrong. At best, we call close again on an invalid FD and throw a spurious EBADF error. At worst, we might close an FD which doesn't belong to us when a multi-threaded application opens its own file descriptor between iterations of the loop.

2013-06-26deps.c: check for indirect deps when orderingAndrew Gregory1-18/+83
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.
