* Cleanup usages of alpm_list_find and alpm_list_remove.Chantry Xavier2008-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * remove obsolete and unused *_cmp helper functions like deppkg_cmp and _alpm_grp_cmp * new alpm_list_remove_str function, used 6 times in handle.c * remove _alpm_prov_cmp / _alpm_db_whatprovides and replace them by a more general alpm_find_pkg_satisfiers with a cleaner implementation. before: alpm_db_whatprovides(db, targ) after: alpm_find_pkg_satisfiers(alpm_db_getpkgcache(db), targ) * remove satisfycmp and replace alpm_list_find + satisfycmp usage by _alpm_find_dep_satisfiers. before : alpm_list_find(_alpm_db_get_pkgcache(db), dep, satisfycmp) after : _alpm_find_dep_satisfiers(_alpm_db_get_pkgcache(db), dep) * remove _alpm_pkgname_pkg_cmp, which was used with alpm_list_remove, and use _alpm_pkg_find + alpm_list_remove with _alpm_pkg_cmp instead. This commit actually get rids of all complicated and asymmetric _cmp functions. I first thought these functions were worth it, be caused it allowed us to reuse list_find and list_remove. But this was at the detriment of the clarity and also the ease of use of these functions, dangerous because of their asymmetricity.

* | Refactor pkg_load/parse_descfile into a new backend fileDan McGee2008-05-11
| | | | | | | | | | | | | | | | | | | | alpm_pkg_load() and parse_descfile() are specific to getting information from package files, just as other code is specific to getting information into or out of a package database. Move this code out of package.c, which should eventually only contain operators on the pmpkg_t struct that do not depend at all on where the data came from.

* | Remove some useless abstraction and start db cleanupDan McGee2008-05-11
| | | | | | | | | | | | | | | | | | | | We have some useless abstractions like an alpm_db_rewind function. I've read somewhere that readdir() was the worst filesystem function call invented, and what do we do? Add a wrapper around it. Kill this abstraction and move some other things into be_files that should be there anyway because they are so tied to how a files backend works. Signed-off-by: Dan McGee <dan@archlinux.org>

* | Add documentation for transaction eventsSebastian Nowicki2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | It is hard to decipher what the transaction events actually notify you of, and what parameters are passed to the callback function, without looking at the code.

* | Rework extract_single_file() temp file creationDan McGee2008-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | We were a bit juryrigged using one call to mkstemp() before rather than extracting the new files side-by-side and doing our comparisons there. We were also facing some permissions issues. Instead, make our life easier by extracting all temp files to a '.paccheck' extension, doing our md5 comparisons, and then taking the correct actions. Still to be done here- a cleanup of the use of PATH_MAX which should not be necessary if we use dynamic allocation on the heap. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Remove unnecessary archive_entry_set_pathname() callsDan McGee2008-04-27
| | | | | | | | | | | | | | I'm not sure why these were ever here, as by this point we have already extracted the file meaning a call to this function is basically a no-op. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Fix some fallout from the delta/download changesDan McGee2008-04-26
| | | | | | | | | | | | | | | | We removed one too many FREELIST() calls when trying to fix some memleaks, and add a safety/sanity check to ensure filename is set, as packages in old DBs are likely to not have this field. Signed-off-by: Dan McGee <dan@archlinux.org>
* | get_filename : use the FILENAME db field only.Chantry Xavier2008-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reference : FS#9547. The get_filename function first tries to get the filename field from the database, and if it doesn't find it, it tries to guess it based on the name, version and arch. 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.

* | Get rid of the delta patches listChantry Xavier2008-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As Nathan noticed, the new informations in the delta struct allows us to get rid of this list : http://www.archlinux.org/pipermail/pacman-dev/2008-February/011163.html So I rewrote apply_deltas for that. The previous apply_deltas also had a limitation: it assumed that the initial package and the deltas were in the first cache dir, which is not necessarily the case. That situation is supported now.

* | 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.

* | Rework delta struct and modify code accordinglyDan McGee2008-04-26
| | | | | | | | | | | | | | | | | | | | Start to move the delta struct away from an assumed package name scheme and towards something that is package (or even filename) agnostic. This will allow us much greater flexibility in the usage of deltas (maybe even sync DBs some day) as well as allowing code outside of delta.h/delta.c to be much cleaner with less of a need for snprintf() calls.

* | Kill compute_requiredby usage in can_remove_package()Nagy Gabor2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | In the can_remove_package function, we don't need to compute the whole requiredby list, we just need to find one member of it that doesn't belong to the targets list. That way we get a small speedup and remove the only usage of alpm_pkg_compute_requiredby in the backend, so that it can be tweaked for frontend usage.

| | | | | | | | | | | | | | | | | | This should remove the need for any additional patching to run on platforms that have libfetch available but not libdownload.

| * More non-Linux build updates, mostly DarwinDan McGee2008-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Darwin's binary format does support symbols with differing visibilities, but it does not support the protected or internal visibilities- only hidden. For Darwin only, we should fall back to this visibility to prevent warnings from the compiler and because it is close enough for our library purposes. See http://gcc.gnu.org/viewcvs/*checkout*/trunk/gcc/config/darwin.c, search for the "darwin_assemble_visibility" function for more details. Also add pacman.static.exe to gitignore.

| * Correctly use the fd returned my mkstemp()Dan McGee2008-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | There were a few issues with this code: 1. We already had an open fd to a file, but never used it to our benefit. Use the libarchive convienence method to write the current file contents straight to a file descriptor. 2. The real problem cropped up on Windows where the locking semantics caused the old way of extraction to fail because we had an open file descriptor. By using the file descriptor and closing it ASAP, we prevent these failures. Signed-off-by: Dan McGee <dan@archlinux.org>

This will be helpful on platforms that currently don't support either libdownload or libfetch (such as Cygwin) and for just compiling a lighter weight pacman binary.

| * Duplicate the result of archive_entry_pathname.Chantry Xavier2008-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the libarchive upgrade from 2.4.12 to 2.4.14, our usage of archive_entry_pathname became dangerous. We were using the result of that function even after calls to archive_entry_set_pathname. With 2.4.14, the entryname becomes wrong after these calls, and so all the future use of entryname are bogus. entryname is used quite a lot for logging, so that's not so bad. But it's also used for the backup handling, so that's not very cool. For example, reinstalling a package with backup entries will erase all the md5 entries from the DB, because they won't be found back. entryname is now a static string so that we can easily keep the result of archive_entry_pathname.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
