pacman/TODO.aaron

== This is my custom TODO file ==

* Make sure all the alpm_list_t changes are valid (especially alpm_list_free)

* src/pacman:
    - There's quite a few single function headers which contain the pacman_*
      functions.  We should move these to a single header (pacman.h) to clean up
      the source a bit.
    - config_t duplicates much of what can be accessed from the alpm_option_*
      interface.  Determine what can / can't be removed and do so.
    - initialize alpm BEFORE parsing args, so we can get rid of a handful of
      local lists and things in pacman.c (see below)
    - fix the "--debug" parameter. requiring a bitmask from the user is silly.
      we can parse this can send a real bitmask to alpm.

* lib/libalpm:
    - Remove `root` param from alpm_initialize.  We can simply initialize to /
      and call set_root at a later time.  This allows us to initiliaze earlier.
    - move logging (alpm_logaction) out of the library.  log files should be
      written by the app, not the library.  Adding a PM_LOG_* constant that
      frontends can recognize and send to a file is probably a good idea.
    - maybe it's my fault, but I see little difference between PM_LOG_FLOW1,
      PM_LOG_FLOW2, and PM_LOG_DEBUG.  We might want to just do away with flow1
      and flow2 and use debug across the board.

* pacman: A LOT of functions are way too long.  There should be an upper limit of
  100-200 lines.  _alpm_add_commit is around 600 lines, and is far too complex.

  Quite a lot of this needs to be refactored as we go.
    Function list (from Dan McGee):
     add.c:
     _alpm_add_commit
     be_files.c:
     _alpm_db_read
     _alpm_db_write
     conflict.c:
     _alpm_checkconflicts
     _alpm_db_find_conflicts
     package.c:
     _alpm_pkg_load (getting a bit long)
     remove.c:
     _alpm_remove_commit
     server.c:
     _alpm_downloadfiles_forreal
     sync.c:
     _alpm_sync_sysupgrade (getting there)
     _alpm_sync_prepare
     _alpm_sync_commit

* pacman: fixup doxygen documentation for public interface

* pacman: use gcc visibility (static) for non-public functions (all _alpm
  functions should be static)

**** BUGS ****
* Removal of conflicts on -A and -U (INCOMPLETE)
* ordering of installed packages based on dependencies
    i.e. pkga depends=(pkgb pkgc), pkgb depends=(pkgc)
    pacman -S pkga pkgb pkgc
    > a depends on b and c, move them: pkgb pkgc pkga
    > b depends on c, move it: pkgc pkgb pkga
    > pacman -S pkgc pkgb pkga
* gensync: get all info from packages instead of PKGBUILDs
  for now, we only need to check the PKGBUILD in case of a
  'force' option
* pacman: add pactest cases/functionality for all -Q operations and make sure
  the output is sane
