* Introduce _alpm_pkg_free_trans()Nagy Gabor2009-06-07
| | | | | | | | | The main purpose of this function to make our code more readable. It frees transaction specific fields of pmpkg_t. (It is used when a package is removed from the target list.) Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>
* Introduce PM_TRANS_FLAG_NOLOCKNagy Gabor2009-06-01
| | | | | | | | | | | | 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).

* Remove pmsyncpkg_tNagy Gabor2009-04-11
| | | | | | | | | | | | | | | | | | | | | 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.

* Revert "popen does NOT require /bin/sh in a subchroot"Xavier Chantry2009-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* runscriptlet : Flush open fds before fork() to avoid cloning buffersXavier Chantry2009-03-15
| | | | | | | | | | | | | | | | | | | | | | 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. In addition, clean up some of the other logic such as directly calling exit(1) on a popen() failure rather than going to our cleanup block, and handling and respecting the exit status of the subprocess correctly.

| * libalpm: handle syscall interruption correctlyDan McGee2008-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* _alpm_db_add_pkgincache reworkNagy Gabor2008-07-15
| | | | | | | | | | | | | | | | | | | | | 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.

* Use access() instead of stat() when possibleDan McGee2008-06-15
| | | | | | | | | | | | | | | | | | | We were using the stat() system call in quite a few places when we didn't actually need anything the stat struct returned- we were simply checking for file existence. access() will be more efficient in those cases.

* Remove trans->targetsNagy Gabor2008-03-10
| | | | | | | | | | | | | | | | | Its implementation was quite broken: * add_loadtarget() might have silently filtered out some targets when replacing an older version. * This was used in sync.c to determine whether a target is implicit or not, which is incorrect behavior. Before this patch we silently removed user confirmed replacements; now we always warn on a replacement. * remove001.py behavior was quite odd in adding same target 5 times to the target list, we can change this behavior to be a failure.

* popen does NOT require /bin/sh in a subchrootAaron Griffin2007-12-10
| | | | | | | | | | | | I appears that when chrooted, the /bin/sh used by popen is that of the parent process. This is true until the process forks once chrooted, which we do not want to do.

* Remove duplicated get_upgrades function, use sysupgrade instead.Chantry Xavier2007-11-21
| | | | | | | | | | | | | | | | The alpm_get_upgrades was exactly the same as find_replacements + _alpm_sync_sysupgrade, except that it automatically made the eventual replacements, without asking the user : Replace %s with %s/%s? [Y/n] The replace question, asked in find_replacements. can now be skipped by using a NULL trans argument, so that we get the same behavior as with alpm_get_upgrades.

* libalpm: introduce MALLOC and CALLOC macrosDan McGee2007-10-29
| | | | | | | | | | | | | | | | | These macros take the place of the common 4 or 5 line blocks of code we had in most places that called malloc or calloc. This should reduce some code duplication and make memory allocation more standard in libalpm. Highlights: * Note that the MALLOC macro actually uses calloc, this is just for safety so that memory is initialized to 0. This can be easily changed in one place. * One malloc call was completely eliminated- it made more sense to do it on the stack. * The use of RET_ERR in public functions (mainly the alpm_*_new functions) was standardized, this makes sense so pm_errno is set.

* libalpm/trans.c : fix a recently introduced breakage in scriptlets handling.Chantry Xavier2007-10-14
| | | | | | | | | | | | | | Commit 4853a4aad97fe36f9237ffb7356201adab507a1c used the tmpdir variable for checking the existence of /bin/sh, without resetting it. This caused /bin/sh to be deleted during the cleanup part, as soon as a scriptlet other than pre_upgrade or pre_install was executed. For example, on the first post_upgrade during a -Su. I introduced two variables : clean_tmpdir and restore_cwd, for deciding what should be done in the cleanup part. Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
* libalpm/trans.c : remove the DBPath <-> RootDir dependence in runscriptlet.Chantry Xavier2007-10-14
| | | | | | | | | | | | This code assumed that DBPath was under RootDir, while this is not necessarily the case : pacman doesn't enforce anymore than DBPath is under RootDir. So now, all scriptlets will be put somewhere in RootDir/tmp/, so that when it chroots in RootDir, the scriptlets are still available inside the chroot. This also removes the need of normalizing both dbpath and rootdir, in order to do computation on the paths. Signed-off-by: Chantry Xavier <shiningxc@gmail.com>

* trans.c : reworking of transaction interruptionsChantry Xavier2007-09-16
| | | | | | | | | | | | | | | | | | | | | | | | | | My two previous hacks related to this part (8038190c7c4786e1c49494eea1b40cdddcbd5136 and b15a5194d1a8485a2769560e49e6ff03e1862533) were caused by the lack of understanding of a feature introduced a while ago: Better control over CTRL-C interruptions -- do not leave the DB in an inconsistent state (54008798efcc9646f622f6b052ecd83281d57cda). Now I have been looking at this commit, and the added feature is indeed interesting. The main problem I had with it is that it does a rather unusual use of alpm_trans_release, which caused a few problems that I tried to fix in a weird way. I think these problems were caused by the fact that there weren't any difference between "interrupt transaction" and "release a transaction which failed" actions from the alpm_trans_release POV. So I decided to add a new function instead, alpm_trans_interrupt, which is called on Ctrl+C, and which only sets trans->state to STATE_INTERRUPTED so that remove_commit and add_commit can exit cleanly at a safe moment. This allowed me to revert my two previous hacks as well. Also ensure we handle SIGINT correctly in all cases- if a transaction is not ongoing, then we can free the transaction and exit quickly.

* libalpm/add.c,trans.c : cleanup of requiredby handling.Nagy Gabor2007-08-20
| | | | | | | | | | | | | | | | | | | | This patch cleans up and fix the _alpm_trans_update_depends function and ensure that all requiredby fields are filled in case of multiple satisfiers (previously, the handling of mutliple satisfiers in that function was inconsistent). This makes a special case handling of requiredby in commit_single_pkg() obsolete, and so allows cleaning that code as well. Also fixed upgrade056 pactest because : 1) the requiredby fields were wrong, and this wouldn't happen with the fixed _alpm_trans_update_depends(). 2) this is a very unusual case anyway (and handling all corner cases combined to a broken database seems nearly impossible to achieve).
