This is more efficient than alpm_list_diff since it assumes the two lists
are sorted. And also we get the two sides of the diff.
Even sorting should more efficient than the current list_diff. Sorting the
two lists should be O(n*log(n)+m*log(m)) while the current list_diff is
O(n*m). So I also reimplemented list_diff using list_diff_sorted.

* 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.

* Introduces 'list == NULL' convention for empty list. That means
alpm_list_new isn't needed anymore, so kill it
* Small straightforward fixes in alpm_list.c

This will allow us to utilize this helpful type and functions in places
besides dependency calculations. In addition, remove the public declaration
of pmgraph_t in alpm.h- there is zero need to expose this internal type.

Update the GPL boilerplate to direct people to the GNU website for a copy of
the license, as well as bump all of Judd's copyrights to 2007.

alpm_list_find and alpm_list_find_ptr will now return a void *, and
alpm_list_find_str will return a char *, instead of an int.

The old alpm_list_find was renamed to alpm_list_find_ptr, and a new
alpm_list_find was introduced, which uses the fn comparison-function
parameter in its decision.
Now both alpm_list_find_ptr (a new ptrcmp helper function was also
added) and alpm_list_find_str are just an alpm_list_find call.

So I spent a good 4 hours tracking a bug down tonight due to
alpm_list_copy_data not actually doing what I expected to do. We can't find
the size of an object we don't know the type of, so rewrite it so we pass
in the size explicitly. This was making _alpm_pkg_dup fail and causing all
sorts of other issues.

Package dup needs to copy all members. Nathan had his implementation, but
I generalized it to this new alpm_list function (and will use it in the
next commit).

We had way too much going on with the Doxygen manpage generation. Clean it
up quite a bit by removing directory manpages, using relative paths, not
having a manpage for every single alpm function, and ensuring internal
functions are not documented publicly.

Add some 'const' keywords all over the code to make it a bit more strict on
what you can and can't do with data. This is especially important when we
return pointers to the pacman frontend- ideally this would always be
untouchable data.

We haven't done a whole lot with Doxygen so far, so this updates some of the
things that have changed a lot- namely, the now public exposure of alpm_list.
All functions in this file have now been Doxygen commented, and a few other
things in alpm.c were fixed as well. In addition, the Doxygen config file
was updated.

* Moved entirely to alpm_pkg_get_* accessors, to read data on demand
* Mostly removed the INFRQ_ parameters from outside the be_files backend (making
the backend more extensible in the long run)
* packages created from _alpm_db_scan now have the db and origin set (making
accessors actually work for these packages)
* removed _alpm_db_ensure_pkgcache
* totally revamped the _alpm_checkconflicts function, making it cleaner and
easier to read (and thus fix in the long run) - maintainable code ftw
NOTE: feel free to rename the functions... I couldn't think of anything better
* removed an extra loop in sync.c:find_replacements - no sense in looping over
an entire DB while strcmp'ing the name, when we have get_pkgfromcache
Other:
* package struct "license" -> "licenses"
* Created _alpm_sync_find (duplicate code in some places, find_pkginsync
* Minor const correctness changes along the way
* fixed a couple extra '/' pathing issues (non-issues really)
* removed a duplicate pkg_cmp function
|
|
* Added some provision switching hackery. This could probably use some
refactoring,.. it solves the following case:
pkg1 and pkg2 provide 'foo' and are both installed
pkg3 depends on 'foo' and so lists 'pkg1' in the REQUIREDBY db section
pkg1 is upgraded and no longer provides 'foo'
** This code ensures that the REQUIREDBY of pkg3 is updated to require pkg2
now instead of pkg1

* Added comment for something I noticed while looking through code
|
|
unbelievable amount of strcmp() calls (25 million) due to the list searching.
This has been reimplemented with a set-intersection scheme, due to the fact
that file lists are always ordered. - NEEDS TESTING
* Minor clean up, "globalized" the str_cmp helper to match the alpm comparison
signature, so we can use it elsewhere.
|
|
* alpm_list_is_in --> alpm_list_find
* alpm_list_is_strin --> alpm_list_find_str
* Flip parameters of both functions to be inline with rest of alpm_list.
First commit, woohoo.

* Added alpm_list_remove_node for single list node removal
* Proper error checking/output for failed db_read/db_write (missing files)
* Invalid packages (missing files) are now removed from the package cache
* -Qs and -Ss output now look the same
* config.rpath causes errors on one machine I had, so I added it to CVS
* Fixed a "clobbered memory" issue when installing groups - only the outer list
should be free'd, not the contained data
|
|
* renamed pmlist_t -> alpm_list_t
* made alpm_list_t a public type (alpm_list.h header)
* removed additional storage for registered DBs in pacman source
* some code cleanup
* removed duplicate (pm)list_display functions from pacman source
* misc code cleanup
