2008-07-17alpm_list_remove treat NULL needle as "nothing"Nagy Gabor
So if you want to remove NULL needle from a list, alpm_list_remove will return with "not found". Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>
2008-05-13Cleanup usages of alpm_list_find and alpm_list_remove.Chantry Xavier
* 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.

2008-02-24More cleanup to alpm_listDan McGee
* Remove some #include statements that are not strictly necessary * Remove node_new function that is really just a one-liner Signed-off-by: Dan McGee <dan@archlinux.org>
2008-02-25alpm_list.c clean-upNagy Gabor
* 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 Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Chantry Xavier <shiningxc@gmail.com>

2007-12-02alpm_list : change the alpm_list_find* to return the matching item.Chantry Xavier
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. Signed-off-by: Chantry Xavier <shiningxc@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
2007-11-20New alpm_list_join functionNagy Gabor
This O(1) function joins 2 lists. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>
2007-11-17Generalized alpm_list_find.Nagy Gabor
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.

2007-11-14Fix alpm_list_copy_dataDan McGee
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. Signed-off-by: Dan McGee <dan@archlinux.org>
2007-11-14alpm_list_add == alpm_list_add_lastNagy Gabor
It's time to define that alpm_list_add(list, foo) adds 'foo' to the end of 'list' and returns with 'list', because: 1. list is a list, not a set. 2. sortbydeps _needs_ an alpm_list_add definition to work properly. As a first step, I used this definition in recursedeps.

2007-11-11Ensure list tail pointer is updated when we remove tail nodeDan McGee
Commit 2ee90ddae23dd86c68223c0d6c49f0b92d62429d did a special check to see if we were removing the head node, but not the tail node. Add a special case for the tail node to ensure all relevant pointers get updated. Signed-off-by: Dan McGee <dan@archlinux.org>

2007-11-06Maintain list tail pointers in the head nodeAaron Griffin
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.

2007-10-29Make general list copy functionDan McGee
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). CC: Nathan Jones <nathanj@insightbb.com> Signed-off-by: Dan McGee <dan@archlinux.org>

2007-07-20libalpm/alpm_list.c : add SYMEXPORT to all alpm_list_ functions.Chantry Xavier
Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
2007-06-05Const correctness!Dan McGee
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. Signed-off-by: Dan McGee <dan@archlinux.org>
2007-05-14Remove unnecessary casts on malloc and elsewhereDan McGee
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. Signed-off-by: Dan McGee <dan@archlinux.org>
2007-04-27Remove FREESERVER macro and correctly type _alpm_server_freeDan McGee
Signed-off-by: Dan McGee <dan@archlinux.org>
2007-03-29Doxygen fixups for libalpmDan McGee
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. Signed-off-by: Dan McGee <dan@archlinux.org>
2007-03-11* Fix group comparison issue and associated compilation warnings by usingDan McGee
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.
2007-03-05This commit looks much more monumental than it is. Almost all just #includeDan McGee
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.
2007-03-03Big commit this time:Aaron Griffin
* 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
2007-03-01* Modified values of INFRQ_* options so we start at 0x01 and not 0x00. ThisDan McGee
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
2007-03-01* Switched some functions to alpm_pkg_get_* usage as I came across themAaron Griffin
* 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
2007-01-30K. Piche <kpiche@rogers.com>Aaron Griffin
* gcc visiblity changes Also modified _alpm_versioncmp -> alpm_versioncmp (public function) as per K. Piche's suggestions
2007-01-30Discussed on IRC for a bit, this makes the following changes for clarity:Dan McGee
* 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.
2007-01-24* Shuffled some of the alpm_list free funtions - still not perfect, but betterAaron Griffin
* 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
2007-01-23* Added some calloc calls to replace the malloc-then-set-to-zero functionalityAaron Griffin
* 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
2007-01-22Introduced an infinite loop during the pmlist -> alpm_list transition, whoopsAaron Griffin
2007-01-19Preliminary checkin for alpm_list conversionAaron Griffin
* 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
