Add two requiredby pactests
One currently should succeed (006), and 005 fails.
requiredby005.py is originally from Nagy Gabor <ngaba@petra.hos.u-szeged.hu>. Well, I'm not sure that pacman should deal with broken localdbs. After we decided that _all_ satisfiers _must_ list the dependency "owner" in their requiredby, this is a broken db. We have a cool testdb stuff (created by you) to help user fix these (an automatized db fix wouldn't be so hard to implement).
Well, nowadays I started to dislike requiredby: 1. The requiredby handling was _very_ negligent earlier, so most users have corrupt localdbs. 2. When the old deps.c just trusted on these fields blindly (-R), these db corruptions caused wrong pacman operation too. After we implemented a slower but more clever checkdeps, all of these problems disappeared. 3. So now a missing requiredby can generate a bug, a false cannot. Note: we use requiredby as a speed-up only (probably speed-up was the main reason for implementing it). 4. Do we really need this speed-up? a.) This is not as efficient as it could be: %REQUIREDBY% should show the dependency also [%REQUIREDBY% gcc:bash>=3.2]; since now foo's %REQUIREDBY% says gcc only, so we have to _scan_ pkgcache for gcc; then check _all_ dependencies of gcc to find the foo-satisfies-this ones. b.) If we didn't use requiredby at all, we should just scan pkgcache (only once!, now we scans it n times, if foo has n requiredby fields), and simply check all depends of all packages to find the satisfied-by-foo dependencies. This would probably slower, and evaluate its degree, but testdb is extremely fast, which makes me optimist.

Update bash completion
Signed-off-by: Dan McGee <dan@archlinux.org>
First of all: Dan, many thanks, great job. Hoverer (don't kill me plz;-), now the new --ignoregroup is missing (maybe others too). We should reach (verify) that bash_completion is up-to-date; and then all new pacman option should trigger a bash_completion update and manual update too to keep that state. I'm sorry for "assigning" new tasks to you (I am a living TODO sometimes here, sry), but I'm not sure that I could hack that correctly [I could "copy" the rules, but I wouldn't take the responsibility for that]:-( Bye, ngaba ---------------------------------------------------- SZTE Egyetemi Könyvtár - http://www.bibl.u-szeged.hu This mail sent through IMP: http://horde.org/imp/
