2011-04-20Header inclusion cleanupDan McGee
This does touch a lot of things, and hopefully doesn't break things on other platforms, but allows us to also clean up a bunch of crud that no longer needs to be there. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-20syntax: if/while statements should have no trailing spaceDan McGee
This is the standard, and we have had a few of these introduced lately that should not be here. Done with: find -name '*.c' | xargs sed -i -e 's#if (#if(#g' find -name '*.c' | xargs sed -i -e 's#while (#while(#g' Signed-off-by: Dan McGee <dan@archlinux.org>
2011-03-20Style change: return(x) --> return xDan McGee
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>
2011-02-22Remove trans->skip_addDan McGee
This is old code that has since gone stale; we no longer ever add anything to this list so no need to keep it around and check the contents during extraction. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-29alpm: drop old target interfacesXavier Chantry
It's likely that these interfaces will break sooner or later, now that pacman no longer uses them. So better force the two people who use them to migrate their code to the new add_pkg/remove_pkg interface, which is very easy anyway. Signed-off-by: Xavier Chantry <chantry.xavier@gmail.com>
2011-01-29alpm: new alpm_add_pkg interfaceXavier Chantry
This new function is meant to deprecate all existing sync/add target functions : int alpm_sync_target(char *target); int alpm_sync_dbtarget(char *db, char *target); int alpm_add_target(char *target); Rather than dropping these 3 interfaces, it might be better to rewrite them using alpm_add_pkg for now.

2011-01-10Remove need for floating point division in backendDan McGee
All of these can be done with integer division; the only slightly interesting part is ensuring we round up like before with calling the ceil() function. We can also remove the math library from requirements; now that the only ceil() calls are gone, we don't need this anymore. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-07Use size_t for alpm_list sizesAllan McRae
There is a lot of swtiching between size_t and int for alpm_list sizes in the codebase. Start converting these to all be size_t by adjusting the return type of alpm_list_count and fixing all additional warnings given by -Wconversion that are generated by this change. Dan: a few more small changes to ensure things compile, adjusting some printf format string characters to accommodate the larger size on x86_64.

2010-12-12Attempt to stop installation when we encounter problemsDan McGee
This should hopefully address some of the concerns raised in FS#11639 with regards to continuing after filling the disk up. Add some more checks and passing of error conditions between our functions. When a libarchive warning is encountered, check if it is due to lack of disk space and if so upgrade it to an error condition. A review of other libarchive warnings suggests that these are less critical and can remain as informative warning messages at this stage. Note the presence of errors after extraction of an entire package is complete. If so, we abort the transaction to be on the safe side and keep damage to a minimum.

2010-10-14Completely separate local and sync db handlingAllan McRae
Put the db_operations struct to use and completely split the handling of the sync and local databases. Signed-off-by: Allan McRae <allan@archlinux.org>
2010-10-14Separate be_files into be_sync and be_localAllan McRae
The file be_files.c is "split" to be_local.c and be_sync.c in order to achieve separate handling of sync and local databases. Some basic clean-up of functions that are only of use for local or sync databases has been performed and some rough function renaming in duplicated code has been performed to prevent compilation errors. However, most of the clean-up and final separation of sync and local db handling occurs in following patches. Signed-off-by: Allan McRae <allan@archlinux.org>

2009-10-11typing: a few more fixes for special int typesDan McGee
Signed-off-by: Dan McGee <dan@archlinux.org>
2009-09-20Fully implement database lazy loadingDan McGee
Commit 34e1413d75 attempted to implement lazy loading of package databases. Although it took care of my main complaint (creating the database directory if it didn't exist), it didn't allow sync repos to be registered before alpm_option_set_dbpath() had been called. With this patch, we no longer compute the individual repository DB paths until necessary, allowing full lazy loading to work as intended, and allowing us to drop the extra setlibpath() calls from the frontend. This allows the changes introduced in a2cd48960 (but later reverted) to be added back in again. Signed-off-by: Dan McGee <dan@archlinux.org>

2009-09-08Remove transaction typeXavier Chantry
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.
2009-09-08Use sync.c for upgrade transaction prepare and commitNagy Gabor
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.

2009-07-20Fix one bug with .paccheck leftover fileXavier Chantry
This happens for example if you install a new package, and one of its backup config file is already on the file system. If the local file was different, it was saved to .pacorig which is fine. However if the local file and pkg file were the same, the pkg file (temporarily extracted as .paccheck) was left on the system.

2009-07-20Fix fileconflict004Xavier Chantry
When one package wants to replace a directory by a file, we check that all files in that directory were owned by that package. Additionally pacman can be more verbose when the extraction of the symlink (or file) fails. The patch to add.c looks more complex than it is, I just moved and reindented code to handle cases 10 and 11 together.

2009-04-11Fix for trans001.py (FS#9088)Nagy Gabor
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>

2009-01-18Use archive_entry_set_perm instead of archive_entry_set_modeNagy Gabor
This patch fixes FS#12148 ('unstable' regular file). I also changed the other archive_entry_set_mode usage in add.c to archive_entry_set_perm. Since I cannot find any relevant info in libarchive manual, I quote Tim Kientzle (the author of libarchive) here, and I say thank you for his help. *** Tim Kientzle wrote ************************************* This is the problem in libalpm/util.c: 323 if(S_ISREG(st->st_mode)) { 324 archive_entry_set_mode(entry, 0644); 325 } else if(S_ISDIR(st->st_mode)) { 326 archive_entry_set_mode(entry, 0755); 327 } Your example unstable.db.tar.gz is not empty. It has one entry in it, called "./". That entry is marked as a directory. But, when you call archive_entry_set_mode(), you are changing the file type! archive_read_extract() then creates the file /var/unstable as you requested. (archive_read_extract() will replace an empty directory with a file.) You should either set the mode value correctly: 323 if(S_ISREG(st->st_mode)) { 324 archive_entry_set_mode(entry, IFREG | 0644); 325 } else if(S_ISDIR(st->st_mode)) { 326 archive_entry_set_mode(entry, IFDIR | 0755); 327 } Or use archive_entry_set_perm(), which does not change the file type: 323 if(S_ISREG(st->st_mode)) { 324 archive_entry_set_perm(entry, 0644); 325 } else if(S_ISDIR(st->st_mode)) { 326 archive_entry_set_perm(entry, 0755); 327 } ************************************************************ Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>

2009-01-02Separate local db directory creation and db writeAllan McRae
Changelogs and install files were getting extracted into the local db folder before it was manually created. This created issues for uses with 0077 umasks and was highlighted with the new sudo handling of umasks (FS#12263). This moves the local db creation to its own function which is called before the start of package archive extraction. Also, added a check that the folder is actually created.

2008-06-04Get rid of double / in database paths.Xavier Chantry
Errors like the following one happen regularly (for unknown reasons...) : error: could not open file /var/lib/pacman/local//glibc-2.7-9/depends: No such file or directory Anyway, every time an user reported an error like that, it always seemed like he thought the error was caused by the double /, which is obviously wrong. Since db->path always include a trailing /, there is no need to add one when concatenating paths in be_files.c or add.c. Additionally, some static strings were switched to dynamic. And the computation of the "dbpath"/"pkgname"-"pkgversion" was refactored in db_read, db_write and db_remove with a get_pkgpath static function.

2008-06-04Use correct C type for file sizesDan McGee
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. Note that at least on Linux, all applications compiled against libalpm must now be sure to use large file support, where _FILE_OFFSET_BITS is defined to be 64 or there will be some weird issues that crop up.

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.
