* Remove global handle dependencies from sync/upgrade pathsDan McGee2011-06-03
| | | | | | | | | This kills a lot more global handle business off. sync.c still requires the handle declaration for one reference that can't be changed yet; it will be removed in a future patch which isolates all of the necesary API changes. Signed-off-by: Dan McGee <dan@archlinux.org>

* Remove ALPM_LOG_FUNC macroDan McGee2011-06-03
| | | | | | | | | The usefulness of this is rather limited due to it not being compiled into production builds. When you do choose to see the output, it is often overwhelming and not helpful. The best bet is to use a debugger and/or well-placed fprintf() statements. Signed-off-by: Dan McGee <dan@archlinux.org>

| * Bail early if we don't have a valid lockfile pathDan McGee2011-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This addresses FS#24292. If one does the bad thing of not checking pm_errno after calling set_dbpath(), you may not realize the initialization process went wrong and calling trans_init() resulted in a segfault. If we don't have a lockfile path, bail out and have trans_init() fail. Also remove a ALPM_LOG_FUNC call that was causing pm_errno to return "no handle"; this was due to a log call in the handle setup (whereby the log attempts to use a callback attached to the handle).

| * trans.c: create transaction prior to checking DB versionDave Reisner2011-05-16
| | | | | | | | | | | | | | | | | | | | | | The addition of the DB version check introduces a lag time between the lockfile creation and the transaction initialization. In cases where the local DB is large enough and/or the user's disk is slow enough, this time is significant enough that its possible for a user to send a SIGINT and leave behind a db.lck file.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was discussed and more or less agreed upon on the mailing list. A huge checkin, but if we just do it and let people adjust the pain will end soon enough. Rebasing should be relatively straighforward for anyone that sees conflicts; just be sure you use the new return style if possible. The following semantic patch was used to do the change, along with some hand-massaging in order to preserve parenthesis where appropriate: The semantic match that finds this problem is as follows, although some hand-massaging was done in order to keep parenthesis where appropriate: (http://coccinelle.lip6.fr/) // <smpl> @@ expression a; @@ - return(a); + return a; // </smpl> A macros_file was also provided with the following content: Additional steps taken, mainly for ASSERT() macros: $ sed -i -e 's#return(NULL)#return NULL#' lib/libalpm/*.c $ sed -i -e 's#return(-1)#return -1#' lib/libalpm/*.c Signed-off-by: Dan McGee <dan@archlinux.org>
* Check local DB version before continuing transactionDan McGee2011-02-28
| | | | | | | | | 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.

* Fix double close of the lock fileJonathan Conder2011-02-27
| | | | | | | | | | 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.

| * Fix possible null pointer deref in check_archDan McGee2010-12-10
| | | | | | | | | | | | | | | | | | | | | | 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.

* | fgets invocation cleanupDan McGee2010-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Remove transaction typeXavier Chantry2009-09-08
| | | | | | | | | | | | | | | 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.
* Use sync.c for upgrade transaction prepare and commitNagy Gabor2009-09-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Introduce -SuuNagy Gabor2009-07-22
| | | | | | | | | | | | | | | 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.

* 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.
