2011-02-28Check local DB version before continuing transactionDan McGee1-2/+13
Ensure we have a local DB version that is up to par with what we expect before we go down any road that might modify it. This should prevent stupid mistakes with the 3.5.X upgrade and people not running pacman-db-upgrade after the transaction as they will need to. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-02-28Move locking functions to where they are neededDan McGee1-7/+48

2011-02-27Fix double close of the lock fileJonathan Conder1-8/+5
According to FOPEN(3), using fclose on an fdopen'd file stream also closes the underlying file descriptor. This happened in _alpm_lckmk (util.c), which meant that when alpm_trans_release closed it again, the log file (which reused the original file descriptor) was closed instead.

2010-12-29Detect undefined PATH_MAXAllan McRae1-0/+1
POSIX does not require PATH_MAX be defined when there is not actual limit to its value. This affects HURD based systems. Work around this by defining PATH_MAX to 4096 (as on Linux) when this is not defined. Also, clean up inclusions of limits.h and remove autoconf check for this header as we do not use macro shields for its inclusion anyway.

2010-12-10Fix possible null pointer deref in check_archDan McGee1-1/+1
If we have a corrupted database, a package can come through without an arch, causing the code to blow up when making strcmp() calls. It might even be possible with perfectly valid database entries lacking an 'arch =' line. This behavior was seen as at least one of the problems in FS#21668. Ensure pkgarch is not null before doing anything further. Signed-off-by: Dan McGee <dan@archlinux.org>

2010-08-23fgets invocation cleanupDan McGee1-2/+3
From the fgets manpage: fgets() reads in at most one less than size characters from stream and stores them into the buffer pointed to by s. Reading stops after an EOF or a newline. If a newline is read, it is stored into the buffer. A '\0' is stored after the last character in the buffer. This means there is no need at all to do 'size - 1' math. Remove all of that and just use sizeof() for simplicity on the buffer we plan on reading into. Signed-off-by: Dan McGee <dan@archlinux.org>

2009-09-08Remove transaction typeXavier Chantry1-198/+173
This basically started with this change : /* Transaction */ struct __pmtrans_t { - pmtranstype_t type; pmtransflag_t flags; pmtransstate_t state; - alpm_list_t *packages; /* list of (pmpkg_t *) */ + alpm_list_t *add; /* list of (pmpkg_t *) */ + alpm_list_t *remove; /* list of (pmpkg_t *) */ And then I have to modify all the code accordingly.
2009-09-08Use sync.c for upgrade transaction prepare and commitNagy Gabor1-13/+3
This patch utilizes the power of sync.c to fix FS#3492 and FS#5798. Now an upgrade transaction is just a sync transaction internally (in alpm), so all sync features are available with -U as well: * conflict resolving * sync dependencies from sync repos * remove unresolvable targets See http://www.archlinux.org/pipermail/pacman-dev/2009-June/008725.html for the concept. We use "mixed" target list, where PKG_FROM_FILE origin indicates local package file, PKG_FROM_CACHE indicates sync package. The front-end can add only one type of packages (depending on transaction type) atm, but if alpm resolves dependencies for -U, we may get a real mixed trans->packages list. _alpm_pkg_free_trans() was modified so that it can handle both target types _alpm_add_prepare() was removed, we use _alpm_sync_prepare() instead _alpm_add_commit() was renamed to _alpm_upgrade_targets() sync.c (and deps.c) was modified slightly to handle mixed target lists, the modifications are straightforward. There is one notable change here: We don't create new upgrade trans in sync.c, we replace the pkgcache entries with the loaded package files in the target list (this is a bit hackish) and call _alpm_upgrade_targets(). This implies a TODO (pkg->origin_data.db is not accessible anymore), but it doesn't hurt anything with pacman front-end, so it will be fixed later (otherwise this patch would be huge). I updated the documentation of -U and I added a new pactest, upgrade090.py, to test the syncdeps feature of -U.

2009-07-22Introduce -SuuNagy Gabor1-2/+2
If the user switches from unstable repo to a stable one, it is quite hard to sync its system with the new repo (the user will see many "Local is newer than stable" messages, nothing more). That's why I introduced -Suu, which treats a sync package like an upgrade, iff the package version doesn't match with the local one's. I added a new pactest (sync104.py) to test this, and I updated the documentation of -Su.

2009-06-01Introduce PM_TRANS_FLAG_NOLOCKNagy Gabor1-12/+20
This flag indicates that the front-end will not call alpm_trans_commit(), so the database needn't be locked. This is the first step toward fixing FS#8905. If this flag is set, alpm_trans_commit() does nothing and returns with an error (that has new code: PM_ERR_TRANS_NOT_LOCKED).

2009-04-11Remove pmsyncpkg_tNagy Gabor1-1/+6
pmsyncpkg_t data sructure was removed: 1. pmpkg_t.reason is used instead of pmsyncpkg_t.newreason. (The target packages come from sync repos, so we can use this field without any problems. Upgrade transaction also uses this field to store this info.) 2. pmsyncpkg_t.removes was moved to pmpkg_t.removes. This step requires careful programming, because we don't duplicate packages when we add them to trans->packages. So we modify sync pkgcache when we add this transaction-only info to our package. Hence it is important to free this list when we remove any package from the target list (remove_unresolvable, remove_conflicts, trans_free), otherwise this could confuse the new sync transactions (with non-pacman GUI). Overall, our code became ~100 line shorter, and we can call our helper functions directly on trans->packages in sync.c, we don't need to maintain parallel package lists.

2009-03-15Revert "popen does NOT require /bin/sh in a subchroot"Xavier Chantry1-7/+0
This reverts commit 9558639d8009483fbf422b138d020745986f82f1. This change was wrong, popen does require /bin/sh in a subchroot. 1) pacman -S lilo -r root Notice no error 2) rm root/bin/sh ; pacman -S lilo -r root Notice an error : error: scriptlet failed to execute correctly Actually, we already get an explicit error here, when popen is run, so there is no need to check for bin/sh explicitely. Besides this check was problematic in some cases. For example, bash itself has a scriptlet, but only post_install and post_upgrade, no pre_install and pre_upgrade. However, since bash has a scriptlet, runscriptlet will also be called before bash is installed. It won't do anything since the scriptlet has no pre_install function. But if we keep the check, we will still get "error : no /bin/sh". Conflicts: lib/libalpm/trans.c Signed-off-by: Xavier Chantry <shiningxc@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
2009-03-15runscriptlet : Flush open fds before fork() to avoid cloning buffersXavier Chantry1-0/+3
This is a bug I noticed 2 years ago : http://www.nabble.com/Re%3A-logging-output-crazy-to11437357.html#a11479679 I thought I fixed it with 57d77eab32c01cd7572a11f76480a3724d09c029 But the bug was still here. Reading man fork, this part caught my attention: * The child inherits copies of the parent's set of open file descriptors. Each file descriptor in the child refers to the same open file description (see open(2)) as the corresponding file descriptor in the parent. This means that the two descriptors share open file status flags, current file offset, and signal-driven I/O attributes (see the description of F_SETOWN and F_SETSIG in fcntl(2)). Since the open file descriptors are inherited, it is probably a good idea to flush them before forking.

We never had a call to pclose() in here before, leaving our file descriptor in some sort of limbo state.

2008-10-12libalpm: handle syscall interruption correctlyDan McGee1-3/+2
It is possible to throw EINTR from a system call such as open(), close(), or waitpid() if custom signal handlers are set up and they are not initialized with the SA_RESTART flag. This was noticed by Andreas Radke when ^C (SIGINT) was given during the call to waitpid(), causing it to throw the EINTR error and we could not accommodate it. Simply wrap these calls in a simple loop that allows us to retry the call if interrupted. Signed-off-by: Dan McGee <dan@archlinux.org>

2008-07-15_alpm_db_add_pkgincache reworkNagy Gabor1-2/+1
Commit 8240da6cb3ff95ad480efe3e1876104024398fae broke some alpm hierarchy and introduced a new memleak (trans->packages was never freed in case of add transaction, even if the transaction wasn't committed), so it is reverted now. We follow a different approach to reduce memory usage: _alpm_db_add_pkgincache doesn't duplicate the whole package before adding it to the cache, only the package name and version (INFRQ_BASE). This method needs very small extra memory (compared to the reverted method), and after transaction commit we use less memory than before (since the big 'files' fields are not copied to cache), this is useful in GUIs. Note: The old add_pkgincache was a bit broken, since pkg->origin wasn't filled in correctly.
