* sync.c : duplicate the target before modifying itXavier Chantry2009-09-20
| | | | | | | | | | | | | | | | | | | | | | | It was probably a bad idea to modify the target directly in case of repo/pkg syntax. Duplicating it also allows us to keep the original target string, which is more informative when printing errors. Also remove a duplicated error message from libalpm, and improve the message already returned to the frontend. $ pacman -S foo/bar before error: repository 'foo' not found error: 'bar': no such repository after error: 'foo/bar': could not find repository for target Signed-off-by: Xavier Chantry <shiningxc@gmail.com> 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.

* Add a new reason field to pmconflict_t structNagy Gabor2009-09-08
| | | | | | | | | | | | | Sometimes "foo conflicts with bar" information is not enough, see this thread: http://bbs.archlinux.org/viewtopic.php?id=77647. That's why I added a new reason field to our pmconflict_t struct that stores the packager- defined conflict that induced the fact that package1 conflicts with package2. I modified the front-end (in callback.c, sync.c, upgrade.c) to print this new information as well. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu>
* 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.

* Give sensible feedback when a repo has no configured serversDan McGee2009-06-08
| | | | | | | | | | | | | | This fixes FS#14899. When running an -Sp operation without servers configured for a repository, we would segfault, so add an assert to the backend method returning the first server preventing a null pointer dereference. In addition, add a new error code to libalpm that indicates we have no servers configured for a repository. This makes -Sy and -S <package> operations fail gracefully and helpfully when a repo is set up with no servers, as the default mirrorlist in Arch is provided this way.

* xdelta : only handle gz compression specificallyXavier Chantry2009-06-06
| | | | | | | | | | | | | | There is apparently no need to handle the re-compression manually when applying a xdelta patch in case of bzip2 or xz.

* Remove find_replacements()Nagy Gabor2009-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | "Foo replaces bar" simply means that "foo is a new version of bar". So this patch refactors the code to use this "rule". _alpm_sync_sysupgrade now does the following for each local package [bar] (pseudo-code): for db in syncdbs { if(db contains bar) {check if db/bar is an upgrade; break;} replacers = find(bar replacers in db); if(replacers!=NULL) {ask_user; break;} } Note: 1. Replacers are grouped per repo. If more than one package replace bar in a repo, all of them are considered ("package set of bar replacers"). 2. If repo1/foo1 and repo2/foo2 both replaces bar, only repo1/foo1 is considered (if repo1 stands before repo2 in pacman.conf). FS#11737 is fixed. 3. It can happen that pacman doesn't consider any replacer, if it found a literal "earlier", so sync132.py modified accordingly (btw, that situation should not appear irl). The new sysupgrade code doesn't use sync_newversion(), so I removed the "local is newer than repo" message, which was annoying with -Qu and SyncFirst.

* Look in target-list first to resolve dependenciesBryan Ischo2009-04-11
| | | | | | | | | | | | | | | This fixes a bug introduced by my previous changes which changes the behavior of IgnorePkg/IgnoreGroup to allow the user to remove unresolvable packages from the transaction. The bug is that the target-list was no longer being consulted first to resolve dependencies, which means that if two packages in the sync database satisfied a dependency, and the user explicitly requested one of those two packages in the sync, the other package was still being pulled in. A new test was added, sync993.py, to verify the desired behavior. Signed-off-by: Bryan Ischo <bji-keyword-pacman.3644cb@www.ischo.com> Signed-off-by: Dan McGee <dan@archlinux.org>

* 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.

* Fix for trans001.py (FS#9088)Nagy Gabor2009-04-11
| | | | | | | | | | | | | | | | | | | | | | | From now on _alpm_db_find_fileconflicts() works with upgrade and remove target lists (like checkdeps), which makes it transaction independent (we still need a trans param because of the progressbar). This is a small step towards the universal transaction. So we call this function directly from sync.c before commiting the remove transaction. This is much safer, but we can get false fileconflict error alarms in some tricky cases ("symlinks puzzle" etc). The patch on find_fileconflict looks complex, but it is mainly an "indent-patch", the new code-part can be found after the /* check remove list ... */ comment, and I modified something around the "file has changed hand" case (see comment modifications in the code). Unfortunately sync.c became more ugly, because we have to create 2 parallel internal transactions: to avoid duplicated work, upgrade transaction is used to load package data (filelists). This problem will disappear, when we finally get rid of internal transactions. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>

| | | | | | | | | | | | | | Resolvedeps reports error when it cannot resolve some dependencies, puts them into the *data list, and set pm_errno. If user removes the unresolvable packages from the target list, we have no error anymore, so from now on we free *data list (we eliminate a memleak) and unset pm_errno.

Fix a bug where download_size == 0 because the packages and deltas are already in the cache, but we still need to build the deltas list and apply the deltas to create the final package. 2) Fix the gzip / md5sum issue by switching to xdelta3, disabling external recompression and using gzip -n in pacman, and disable bsdtar compression and using gzip -n in makepkg.

* libalpm: remove from_md5 and to_md5 from pmdelta_tXavier Chantry2009-02-28
| | | | | | | | | | | | | The from_md5 and to_md5 fields were a nice extra safety, which would avoid trying to apply deltas on corrupted package files. However, they are not strictly necessary, since xdelta should be able to detect that on its own. The main problem is that it is impossible to compute these informations from the delta only. So repo-add would not be able to compute the delta entry based on just the delta file. Signed-off-by: Xavier Chantry <shiningxc@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>

Many pactest tests that used to fail now return success codes, because pacman now issues a prompt allowing the user to cancel rather than failing many transactions, and the pactest scripts always choose to cancel with no error rather than failing.

* sync_addtarget reworkNagy Gabor2008-07-13
| | | | | | | | | | | | | | | | | | | | | | Now '-S provision' handling is done in the back-end. In case of multiple providers, the first one is selected (behavior change: deleted provision002.py). The old processing order was: literal, group, provision; the new one: literal, provision, group. This is more rational, but "pacman -S group" will be slower now. "pacman -S repo/provision" also works. Provision was generalized to dependencies, so you can resolve deps by hand: "pacman -S 'bash>2.0'" or "pacman -S 'core/bash>2.0'" etc. This can be useful in makepkg dependency resolving. The changes were documented in pacman manual. alpm_find_pkg_satisfiers and _alpm_find_dep_satisfiers functions were removed, since they are no longer needed.

* Resolvedeps reworkNagy Gabor2008-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I divided resolvedeps into 2 functions. The new _alpm_resolvedep function will resolve one dependency, for example the 'foo>=1.0-1' dependency. It can be useful in sync_addtarget refactoring. The resolvedeps parameters were changed, to be coherent with recursedeps: * the target-list is an alpm_list* instead of alpm_list**. This is OK, because alpm_list_add == alpm_list_add_last * syncpkg param was removed. list contains the to-be-installed packages, resolvedeps will add the required dependencies into this list * trans param was removed, it was used in QUESTION() only, which can be used on the main (handle->trans) transaction only (because the front-end cannot access our pseudo-transactions at all!). The patch fixes some wrong dynamic pmdepmissing_t usage. I did a behavior change (and sync1003.py was modified accordingly), which needs some explanation: The old resolvedeps didn't elect packages from 'remove' list. I've dropped this because I don't want that 2nd excluding list param. In fact, in real life, we ~never need this rule. Resolvedeps is called before checkconflicts, so only -Su's %REPLACES% packages are sitting in 'remove' list. This means, that we have the replacement packages in our target list. Usually "foo replaces bar" means, that bar isn't in our repos any more, so resolvedeps *cannot* elect it; but usually it won't try it at all, because foo is in the target list, and it is expected to satisfy 'bar>=1.0-1'-like dependencies too. Since checkdeps and checkconflicts is done after resolvedeps, this cannot cause any harm. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>
* Reimplement TotalDownload functionalityDan McGee2008-06-04
| | | | | | | | | | | | Add a new totaldlcb callback function to libalpm and make pacman utilize it when the TotalDownload option is enabled. This callback function is pretty simple- it is meant to be called once at the beginning of a "list download" action, and once at the end (with value 0 to indicate the list has been finished). The frontend is responsible for keeping track of adding individual file download amounts to the total xfered amount in order to display some sort of overall progress.

| | | | | | | | | | | | | | We have been using unsigned long as a file size type for a while, which works but isn't quite correct and could easily break. Worse was probably our use of int in the download callback functions, which could be restrictive for packages > 2GB in size. Switch all file size variables to use off_t, which is the preferred type for file sizes.

This field was introduced in 3.0, but there are still many old entries in the official databases without it. So the databases need to be regenerated first before this patch can be applied. There is a second problem with the delta code, which needs the filename for locally installed packages too, but this field is not present in the local db. So the delta code needs to be fixed first.

* Completely rework delta algorithmChantry Xavier2008-04-26
| | | | | | | | | | | | | | | | | | | | Using the graph structures that Nagy set up for dependency sorting, we now do a similar process for deltas. Load up all of the deltas into a graph object on which we can then apply Dijkstra's algorithm, using the new weight field of graph struct. We initialize the nodes weight using the base files that we can use in our filecache (both filename and md5sum must match). The algorithm then picks the best path among those that can be resolved. Note that this algorithm has a few advantages over the old one: 1. It is completely file agnostic. These delta chains do not have to consist of package files- this could be adopted to do delta-fied DBs. 2. It does not use the local_db anymore, or even care if a package or file is currently installed. Instead, it only looks in the filecache for files and packages that match delta chain entries.

* Avoid duplicated target names.Nagy Gabor2008-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | This patch should avoid duplicated target names in the backend. 1. sync_loadtarget will return with PM_ERR_TRANS_DUP_TARGET when trying to add a duplicated target 2. sysupgrade never pulls duplicated targets 3. resolvedeps won't pull duplicated targets anymore A pulled list was introduced in sync_prepare to improve the pmsyncpkg_t<->pmpkg_t list conversion by making it more direct. Also replace sync1005 and sync1006 by the sync1008 pactest, which is similar but more interesting (the provisions are dependencies instead of explicit targets). sync1005 didn't work as expected anyway. It was expecting that pacman failed, and pacman indeed failed, but not for the good reason. It didn't fail during the preparation step because of conflicting targets, but during the commit step, because of a md5 error... And sync1006 didn't pass and was not really worth fixing. We have already enough failing pactests more important than these two. sync1008 pass with this patch.

* 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.

* libalpm: clean up of md5sum functions.Chantry Xavier2008-02-27
| | | | | | | | | test_delta_md5sum and test_pkg_md5sum were simple wrappers to test_md5sum, and only used once, so not very useful. I removed them. Also, test_md5sum and alpm_pkg_checkmd5sum functions were a bit duplicated, so I refactored them with a new _alpm_test_md5sum function in libalpm/util.c Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
