* Add events on pacnew/pacsave/pacorig file creationOlivier Brunel2014-03-03
| | | | | | | | | | | | | | ALPM still adds a warning to the log, but doesn't emit an event about said warning, instead using a specific event to let the frontend what happened/how to inform the user. Note that there are 2 cases for installing a .pacnew file, to not overwrite user changes and because file is in NoUpgrade. In the later case the warning was a bit different: it happened before and said "extracting" instead of "installed." Now both happen after and are phrased the same.

* restrict transaction package originsAndrew Gregory2014-03-03
| | | | | | | | | This moves the "wrong args" error up from trans_commit to add_pkg when used with a local pkg and adds the error for remove_pkg when used with a sync pkg, which currently just removes the db entry.

* Update the event callbackOlivier Brunel2014-03-03
| | | | | | | | | | | | Instead of using two void* arguments for all events, we now send one pointer to an alpm_event_t struct. This contains the type of event that was triggered. With this information, the pointer can then be typecasted to the event-specific struct in order to get additional arguments.

* Remove ts and sw from vim modeline when noet is setFlorian Pritz2014-01-28
| | | | | | | | | | | | Forcing vim users to view files with a tabstop of 2 seems really unnecessary when noet is set. I find it much easier to read code with ts=4 and I dislike having to override the modeline by hand. Command run: find . -type f -exec sed -i '/vim.* noet/s# ts=2 sw=2##' {} + Signed-off-by: Florian Pritz <bluewind@xinu.at> Signed-off-by: Allan McRae <allan@archlinux.org>

* log important events from the backendAndrew Gregory2013-11-15
| | | | | | | | | | | | | 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.

* sortbydeps: include local pkgs in dep graphAndrew Gregory2013-10-31
| | | | | | | | | | | | | | | | 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.

* Do not resolve every local package filelist on removeAllan McRae2013-03-07
| | | | | | | | | | Although technically correct, this results in my system taking ~30 seconds to resolve all filelists when removing a package that has a directory not owned by any package. The check for if any package own the empty directory is a rare enough occurance, and it will be even rarer when that directory has a directory symlink in its path, so just revert this at this stage.

* use resolved_path for filelist_containsAndrew Gregory2013-02-24
| | | | | | | | | | | alpm_filelist_contains was being used to search for resolved paths, but searching in the unresolved paths, causing it to miss matches. We always search unresolved paths and search the resolved paths if available because _alpm_filelist_resolve is not public and requires a context handle, so it can't be called from alpm_filelist_contains.

* libalpm: never attempt to remove a mountpointDave Reisner2013-02-16
| | | | | | | | | | | | | | | | | | | | | | | Arch Linux typically runs into this with /sys when upgrading the filesystem package in build chroots, but LXC users might also run into this, since their /sys is shared from the host and must, for security reasons, be mounted RO. I've neglected to add any tests for this because they would require root in order to run. Current tests all pass with this patch and I've confirmed the desired behavior in a VM. Incidentally, the first hunk of this patch (skipping can_remove_file checks for directories) resolves the case of API mountpoints being removed since they eventually fall into unlink_file and fail with "contains files". However, this patch should still be the Right Thing To Do™, as we can't possibly remove a directory that is also a mountpoint. Signed-off-by: Dave Reisner <dreisner@archlinux.org> [Allan] Do not skip checking if directories can be removed. Instead test if directories are mountpoints in can_remove_file.

* Save backup files with extension .pacsave.nPang Yan Han2013-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Teach pacman to save backup files with extension .pacsave.n, where n is a positive integer. The current backup file shall be saved as <name>.pacsave, while existing .pacsave.n files will be renamed to <name>.pacsave.n+1 Example: 1. You have subversion installed in your local repo. /etc/conf.d/svnserve is a file to be backed up. It contains local modifications 2. You remove subversion from your repo. /etc/conf.d/svnserve is backed up as /etc/conf.d/svnserve.pacsave 2. You install subversion again 3. You edit /etc/conf.d/svnserve 4. You remove subversion. The existing /etc/conf.d/svnserve.pacsave is renamed to /etc/conf.d/svnserve.pacsave.1 and /etc/conf.d/svnserve is backed up as /etc/conf.d/svnserve.pacsave Signed-off-by: Pang Yan Han <pangyanhan@gmail.com> Rebased from original email and adjusted for util-common usage.

* Move filelist functions into separate source fileDan McGee2012-08-02
| | | | | | | | | We have a few of these and might as well gather them together. This also cleans up the code a bit by using an enum instead of integer values, as well as makes a "search for file in filelist" function public so frontends can do better than straight linear search of the filelists.

* | Rework package removal codeDan McGee2011-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extract the actual unlinking of files into a new method, which eliminates a goto used for flow control. Also fix up a few small issues in the code: * Unnecessary (unsigned long) cast, use '%zd' instead * Total up errors returned from unlink_file calls and return to caller * Be consistent with scriptlets- we run pre_remove on dbonly, so we should also run post_remove. Both can be disabled by way of the --noscriptlet argument. * Don't pass an invalid pointer to oldpkg to the event callbacks; instead call the callback before we free the object.

* | include config.h via MakefilesDave Reisner2011-12-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ensures that config.h is always ordered correctly (first) in the includes. Also means that new source files get this for free without having to remember to add it. We opt for -imacros over -include as its more portable, and the added constraint by -imacros doesn't bother us for config.h. This also touches the HACKING file to remove the explicit mention of config.h as part of the includes.

* | Large performance improvement for check for owned directoriesDan McGee2011-10-14
|/ | | | | | | | | | | | | | | | | | | | We can take a large shortcut here that saves us a lot of time, especially when upgrading packages with lots of directories. Obviously iterating the full file list of every single package to determine if this directory was present in any other package can take quite some time on a system with many packages installed. We don't need to remove a directory at all if we are upgrading a package and the version we are moving to still had the directory. Also make a small optimization on the package comparsion- we really only care about equality here, not the result of the compare, so we can shortcut using our name_hash. What kind of benefit does this give us? Oh, only a reduction from 295.7 million to 1.4 million strcmp() calls (99.5% fewer) during a `pacman -S linux libreoffice-common` operation.

* Revamp scriptlet path formation for scriptlets in local databaseDan McGee2011-09-30
| | | | | | | | | Expose the current static get_pkgpath() function internally to the rest of the library as _alpm_local_db_pkgpath(). This allows use of this convenience function in add.c and remove.c when forming the path to the scriptlet location. Signed-off-by: Dan McGee <dan@archlinux.org>
* Refactor _alpm_runscriptlet()Dan McGee2011-09-30
| | | | | | | | | | Add an is_archive parameter to reduce the amount of black magic going on. Rework to use fewer PATH_MAX sized local variables, and simplify some of the logic where appropriate in both this function and in the callers where duplicate calls can be replaced by some conditional parameter code. Signed-off-by: Dan McGee <dan@archlinux.org>
* Move pacsave path construction code off the stackDan McGee2011-09-28
| | | | | | | This is definitely not in the normal hot path, so we can afford to do some temporary heap allocation here. Signed-off-by: Dan McGee <dan@archlinux.org>
* Be smarter about running ldconfig during removal transactionsDan McGee2011-09-19
| | | | | | | | | | 1. Don't run it if something failed in package removal- this mirrors what we already do in sync transactions. 2. Don't run it if we are invoking it for the replaces removal bit of a sync transaction- it doesn't make sense to run ldconfig halfway through a sync install; we should only run it once at the end.

* Search for non-prefixed paths in skip_remove listDan McGee2011-09-19

* Former transaction callback rename refactorDan McGee2011-09-02
| | | | | | | | | | | | | Put all the callback stuff in alpm.h in one spot, and make the following renames for clarity with the new structure: ALPM_TRANS_EVT_* --> ALPM_EVENT_* ALPM_TRANS_CONV_* --> ALPM_QUESTION_* ALPM_TRANS_PROGRESS_* --> ALPM_PROGRESS_* alpm_option_get_convcb() --> alpm_option_get_questioncb() alpm_option_set_convcb() --> alpm_option_set_questioncb() Signed-off-by: Dan McGee <dan@archlinux.org>
* Move all callbacks up to the handle levelDan McGee2011-09-02
| | | | | | | | | This was just disgusting before, unnecessary to limit these to only usage in a transaction. Still a lot of more room for cleanup but we'll start by attaching them to the handle rather than the transaction we may or may not even want to use these callbacks. Signed-off-by: Dan McGee <dan@archlinux.org>
* Be more robust when copying package dataDan McGee2011-08-19
| | | | | | | | | | | | | | | | This changes the signature of _alpm_pkg_dup() to return an integer error code and provide the new package in a passed pointer argument. All callers are now more robust with checking the return value of this function to ensure a fatal error did not occur. We allow load failures to proceed as otherwise we have a chicken and egg problem- if a 'desc' local database entry is missing, the best way of restoring said file is `pacman -Sf --dbonly packagename`. This patch fixes a segfault that was occurring in this case. Fixes the segfault reported in FS#25667. Signed-off-by: Dan McGee <dan@archlinux.org>
* Remove use of no-op accessor functions in libraryDan McGee2011-08-18
| | | | | | | | | The functions alpm_db_get_name(), alpm_pkg_get_name(), and alpm_pkg_get_version() are not necessary at all, so remove the calling and indirection when used in the backend, which makes things slightly more efficient and reduces code size.

* Check return value of rename() callsDan McGee2011-08-08
| | | | | | | | | We did a good job checking this in add.c, but not necessarily anywhere else. Fix this up by adding checks into dload.c, remove.c, and conf.c in the frontend. Also add loggers where appropriate and make the message syntax more consistent. Signed-off-by: Dan McGee <dan@archlinux.org>
* Convert package filelists to an array instead of linked listDan McGee2011-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This accomplishes quite a few things with one rather invasive change. 1. Iteration is much more performant, due to a reduction in pointer chasing and linear item access. 2. Data structures are smaller- we no longer have the overhead of the linked list as the file struts are now laid out consecutively in memory. 3. Memory allocation has been massively reworked. Before, we would allocate three different pieces of memory per file item- the list struct, the file struct, and the copied filename. What this resulted in was massive fragmentation of memory when loading filelists since the memory allocator had to leave holes all over the place. The new situation here now removes the need for any list item allocation; allocates the file structs in contiguous memory (and reallocs as necessary), leaving only the strings as individually allocated. Tests using valgrind (massif) show some pretty significant memory reductions on the worst case `pacman -Ql > /dev/null` (366387 files on my machine): Before: Peak heap: 54,416,024 B Useful heap: 36,840,692 B Extra heap: 17,575,332 B After: Peak heap: 38,004,352 B Useful heap: 28,101,347 B Extra heap: 9,903,005 B Several small helper methods have been introduced, including a list to array conversion helper as well as a filelist merge sort that works directly on arrays.
