2010-12-13Merge desc and depends files in local dbAllan McRae3-94/+61
Whenever depends is needed from the local db, so is desc. The only disadvantage to merging them is the additional time taken to read the depends entries when they are not needed. As depends is in general relatively small, the additional time taken to read it in will be negligable. Also, merging these files will speed up local database access due to less file seeks.

2010-12-13Attempt to stop installation when we encounter problemsDan McGee1-32/+48
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.

2010-12-13Turn libarchive warnings into libalpm warningsDan McGee2-3/+3
Rather than hiding these warnings, show them to the user as they happen. This will prevent things such as hiding full filesystem errors (ENOSPC) from the user as seen in FS#11639.

2010-12-13Make reading from any file possible in sync DBDan McGee1-12/+8
Whether it be "desc", "depends", or "deltas", it really doesn't matter- treat them all the same and have the ability to read any data from any file in that list. This continues the work in a44c7b8956. Signed-off-by: Dan McGee <dan@archlinux.org>

* Use our normal return() function syntax * Rework a few things to reduce number of casts * Fix void function argument declaration * Add missing gettext _() call * Remove need for seperate malloc() of statvfs/statfs structure * Unify argument order of static functions- mountpoints now always passed first * Count all files that start with '.' in a package against the DB * Rename db to db_local in check_diskspace to clarify some code * Fix some line wrapping to respect 80 characters Signed-off-by: Dan McGee <dan@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>
2010-12-13Refactor statfs/statvfs type checkDan McGee2-41/+21
Turn it into a configure-type typedef, which allows us to reduce the amount of duplicated code and clean up some #ifdef magic in the code itself. Adjust some of the other defined checks to look at the headers available rather than trying to pull in the right ones based on configure checks.

2010-12-13Add functions to calculate approximate disk usage by packagesAllan McRae1-0/+100
Two helper function are added to calculate the disk usage from packages that are either currently installed on the system or from a package archive. Some minor approximations have been made: 1. Size for directories is not considered when removing a package from the filesystem to avoid multiple counting across packages. Also, these are reported to take zero size while installing. 2. Symlinks are reported to contribute zero size towards removal as libarchive reports them to have zero size for install. 3. Package data files (.PKGINFO, .INSTALL, .CHANGELOG) are counted towards usage on dbpath on install, but their size is not counted on package removal. 4. No handling of extra size needed for .pacsave/.pacnew files. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

2010-12-13alpm: don't expose alpm_depcmpXavier Chantry5-9/+9
Either we expose all low levels function dealing with pmdepend_t (splitdep and depfree come to mind), or we don't. Since none of the tools use depcmp, I chose to remove it. In the future, we might want to expose higher level functions such as alpm_find_satisfier, or just lower level functions like splitdep and depfree together with depcmp.

whatprovides and splitdep were removed, so depcmp alone is quite useless now without splitdep, and deptest is not flexible enough.

This patch is only meant for 3.4.x. It prepares the place for the future epoch-aware release.

2010-12-11Fix possible null pointer deref in check_archDan McGee1-1/+1
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.

[Y/n] ( 1/15) removing kde-meta-kdewebdev [------------------------] 100% $ it stopped here.. On one side, libalpm did not initialize the progress bar at 0 percent. So with meta-packages that have 0 files, there was only one progress bar call with percent == 100. On the other side, pacman callback kept track of the last percent that it received. When there are only meta-packages, we always received only 100, so pacman believed the progress bar needed not update. Thus only the first package was actually displayed. A proper fix for the callback would be to keep track of last package name to make sure the recorded prev percent applies. But since we now specify that both Add and Remove should at least send percent=0 at beginning and percent=100 at the end, there is no need for that.

2010-10-14Separate be_files into be_sync and be_localAllan McRae8-325/+943
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>

2010-10-13Complete rework of package accessor logicDan McGee5-92/+398
Hopefully we've finally arrived at package handling nirvana, or at least this commit will get us a heck of a lot closer. The former method of getting the depends list for a package was the following: 1. call alpm_pkg_get_depends() 2. this method would check if the package came from the cache 3. if so, ensure our cache level is correct, otherwise call db_load 4. finally return the depends list Why did this suck? Because getting the depends list from the package shouldn't care about whether the package was loaded from a file, from the 'package cache', or some other system which we can't even use because the damn thing is so complicated. It should just return the depends list. So what does this commit change? It adds a pointer to a struct of function pointers to every package for all of these 'package operations' as I've decided to call them (I know, sounds completely straightforward, right?). So now when we call an alpm_pkg_get-* function, we don't do any of the cache logic or anything else there- we let the actual backend handle it by delegating all work to the method at pkg->ops->get_depends. Now that be_package has achieved equal status with be_files, we can treat packages from these completely different load points differently. We know a package loaded from a zip file will have all of its fields populated, so we can set up all its accessor functions to be direct accessors. On the other hand, the packages loaded from the local and sync DBs are not always fully-loaded, so their accessor functions are routed through the same logic as before. Net result? More code. However, this code now make it roughly 52 times easier to open the door to something like a read-only tar.gz database backend. Are you still reading? I'm impressed. Looking at the patch will probably be clearer than this long-winded explanation.

2010-10-13Allow local and sync db to be treated separatelyDan McGee5-34/+37
Implement this seemingly simple change in package.h: typedef enum _pmpkgfrom_t { - PKG_FROM_CACHE = 1, - PKG_FROM_FILE + PKG_FROM_FILE = 1, + PKG_FROM_LOCALDB, + PKG_FROM_SYNCDB } pmpkgfrom_t; which requires flushing out several assumptions from around the codebase with regards to usage of the PKG_FROM_CACHE value. Make some changes where required to allow the switch, and now the correct value should be set (via a crude hack) depending on whether a package was loaded as an entry in a local db or a sync db.
