Remove old TODO lists
These had not been touched since 2007 and had lost most of their relevance. The bug tracker is a better place for the filing of ideas. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

== This is my custom TODO file ==
|
||||
|
||||
* transaction object should contain two package list (install and remove)
|
||||
instead of a single list of syncpkgs - this should allow us to get rid of that
|
||||
type. This also requires seperate functionality to return a list of
|
||||
"replaces" packages to the front end, so the frontend can handle the QUESTION()
|
||||
stuff in that case
|
||||
|
||||
* libalpm -> front end communication needs a work-up. Both progress functions
|
||||
can be combined into one callback, IFF we adjust it to accept a prefix string
|
||||
for the progress bars, and format it at the lib side. Question functions
|
||||
should also do the same - create the string at the library side, and simply
|
||||
call some sort of int yes_no = ask_question("Do foo with bar?");
|
||||
|
||||
* 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.
|
||||
|
||||
* clear up list allocation/deallocation - some lists need to be free'd, some
|
||||
do not and there is no clear indication WHEN this should happen.
|
||||
|
||||
* remove DB entries (directories) on a read error?
|
||||
|
||||
* Add a pm_errstr error string, which will allow us to do things like:
|
||||
pm_errno = PM_ERR_LIBARCHIVE;
|
||||
pm_errstr = archive_error_string(archive);
|
||||
or:
|
||||
pm_errno = PM_ERR_LIBDOWNLOAD;
|
||||
pm_errstr = downloadLastErrString;
|
||||
This way we don't break abstraction when returning specific errors in
|
||||
cases like the above.
|
||||
|
||||
* 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.
|
||||
|
||||
* pacman: fixup doxygen documentation for public interface
|
||||
|
||||
* feature for 3.1: package file hooks *
|
||||
I've been planning on this one for some time. Here's a simple rundown:
|
||||
in /etc/pacman.d/hooks:
|
||||
Hook /usr/include/* : /usr/bin/ctags -R /usr/include/*.h -f /usr/include/systags
|
||||
This will allow us to make "global hooks" to simplify a lot of repetitive
|
||||
install files (scrollkeeper, depmod, etc). This also allows us to move
|
||||
ldconfig out of pacman entirely.
|
||||
possible: /etc/pacman.hooks/* files for hooks, so packages can add them too
|
||||
|
||||
* feature for 3.1: multiple search/match types
|
||||
option: MatchType regex (current way)
|
||||
MatchType fnmatch (use fnmatch to match things like 'pacman -S gnome*')
|
||||
MatchType plain (no matching. expect plain text).
|
||||
|
||||
* feature for 3.1: revamp the autotools system. I'd LOVE to use a manual system
|
||||
like wmii and friends do. It'd be real nice if we could just do away with
|
||||
autotools altogether.
|
||||
|
||||
**** BUGS ****
|
||||
* Removal of conflicts on -A and -U (INCOMPLETE)

========
|
||||
|
||||
This is my personal TODO list. No guarantees if it is out of date and things no
|
||||
longer apply. If you want to help out with any of it, send me an email.
|
||||
|
||||
Pacman 3.1:
|
||||
-----------
|
||||
|
||||
Downgrade feature - allow users to see cached packages and downgrade to
|
||||
(previous or any?) available options.
|
||||
|
||||
Extreme similarity between some of the sync and add code...we have to be able
|
||||
to abstract more away from sync actions and add actions to just 'actions'
|
||||
(example: sync,c, add.c, and deptest.c all contain a switch on PM_DEP_MOD_*).
|
||||
Merge update, add, and sync code when possible, so we reduce duplication.
|
||||
|
||||
Review progress/transaction event subsystem. (from TODO)
|
||||
|
||||
Add Doxygen comments to every function in libalpm including private functions.
|
||||
Ensure functions are doing exactly their purpose and nothing more. Find
|
||||
functions that perform duplicate behavior and merge them. Combine and refactor
|
||||
others. Delete unnecessary functions. Stop keeping everything clustered in
|
||||
little add/sync/remove parts, allow transactions to share code.
|
||||
|
||||
Go through options list. Decide if namings are good, all options are still
|
||||
relevant, etc. Ideas for -Re (#6273), changing meaning of -c (has two meanings,
|
||||
another FS bug), etc. Remove the -A flag and possibly -D, -T, and -Y (-Y is
|
||||
killed now in favor of vercmp binary) if they can be done by other actions.
|
||||
Possible switch of -U --> -I (#5571).
|
||||
|
||||
Review display and logging functions. There seems to be an abundance of them.
|
||||
Make it extensible to use color, review what verbose/debug means. Perhaps
|
||||
separate logging functionality- Pacman has its normal log, and alpm backend
|
||||
keeps a very simple log file - listing only adds (including syncs) and removes.
|
||||
This way a consistency list can be kept of what is currently installed and what
|
||||
isn't, without all the logging junk from the front end.
|
||||
|
||||
Profile the code. Find the functions that are being called a lot, and see what
|
||||
can be done about it. Find out if all these calls are necessary (e.g. excessive
|
||||
alpm_list_count calls), and maybe think about changing data structures to speed
|
||||
operations up (e.g. a 'count' field). NOTE: already found two huge issues with
|
||||
quick profiling- excessive setlocale calls, and extremely excessive strcmp
|
||||
calls.
|
||||
|
||||
Fix other localized issues- use non-printf when necessary. We may need to use
|
||||
some wchar_t output on the progress bar as char/byte counts differ here. Sizes
|
||||
of packages (e.g. 10,400.23 MB) should all be localized with correct
|
||||
seperators.
|
||||
|
||||
Rewrite makepkg to use terminal-safe coloring/bolding. tput utility should
|
||||
allow us to do this. Make universal message functions for systemwide use,
|
||||
including all pacman utilites- abs, pacman-optimize, etc.
|
||||
|
||||
Bugs/FRs to smash: 6468, 6437, 6430?, 6420, 6404, 6389, 6312?, 6284, 6273?,
|
||||
6255?, 6208, 5987, 5885, 5571, 4182, 3492, 2810?, 1769, 1588, 1571
|
||||
|
||||
Update doxygen comments, they may need some work. Try to document all of the
|
||||
private internal functions too- it helps a ton for people just getting a
|
||||
start on pacman hacking.
|
||||
|
||||
Other smaller things:
|
||||
---------------------
|
||||
|
||||
unsigned int vs. unsigned- determine a standard and stick with it
|
||||
|
||||
FS #4185 - move where message is logged, perhaps?
|
||||
|
||||
Update copyrights (2007)
|
||||
|
||||
Update pacman website, and add/finish pacman coding style page
|
||||
|
||||
Refine makepkg error codes. Each kind of failure could have its own code:
|
||||
--package already built
|
||||
--failed integ checks
|
||||
--failed build
|
||||
--etc.
|
||||
|
||||
Revamp the downloadprog function a bit. Seems kind of messy.
|
||||
|
||||
--print-uri option to sync should not require saying yes or no to up to date
|
||||
|
||||
Build a replacement for this, or at least standardize its use. We shouldn't
|
||||
always need to pass handle->root around, it is constant. Something like char*
|
||||
buildpath(file).
|
||||
/* build the new entryname relative to handle->root */
|
||||
snprintf(filename, PATH_MAX, "%s%s", handle->root, entryname);
|
||||
|
||||
Random ideas:
|
||||
-------------
|
||||
|
||||
Possibly split utilities/extras from pacman package
|
||||
|
||||
Make .indent.pro file for GNU indent (started, but didn't finish)
|
||||
