List head nodes contain null 'prev' pointer, which we can (ab)use to maintain a
back reference to the tail pointer of the list.
While list additions are not _significantly_ improved, they are still sped up.

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).

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 had many unnecessary casts, most of them dealing with malloc and
other memory allocations. The variable type should take care of it;
no need to do it explicitly. In addition, I caught a const error while
removing the casts.

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.

the alpm strcmp operation which takes void* references.
* We had this great visibility patch, but never actually took advantage of
it. Added the right compile flag to make it work and added some more
SYMEXPORTs where necessary to have a successful compile.
|
|
reordering and adding ones that were forgotten (noticed when trying to
compile after reordering).
* Updated the HACKING file to include information on #include usage.
* print -> vprint in "making dir" function in pactest.
|
|
* 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

allows for the same bit operators to be used across the board on pkg_get
operations.
* Changed name of INFRQ_NONE -> INFRQ_BASE to more clearly reflect what it
does (loads pkg name and version).
* Added a few missing things on package functions, such as SYMEXPORT and
ALPM_LOG_FUNC.
* Slight updates to pmenv to print 'pass' and 'fail' instead of 'passed' and
'failed'. Keeps output a bit more concise.
* Fixed a doxygen comment spelling error. :P
|
|
* 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
|
|
* gcc visiblity changes
Also modified _alpm_versioncmp -> alpm_versioncmp (public function) as per K.
Piche's suggestions
|
|
* 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
|
|
* Fixed -Ss output so as not to call alpm_list_getdata with a NULl list
* Added a NULL check in alpm_list_getdata
* Fixed alpm_list_add_sorted to properly handle a new / beginning insertions
|
|
|
|
* 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
