[gentoo-dev] Little prog to check compile-options for packages.

[gentoo-dev] Little prog to check compile-options for packages.

[Daniel Armyr]

I thik I am the only one in the world who is interested in this feature, 
but since I took the time to write the prog I can just as well post it. 
It requires an installed portage, and being a python script obviously 
python. I think some of you have issues with long emails, so I'll link 
the code. Just save and make sure to set permissions. Then run >qflag 
[substring] to display all packages with the given substring.

Nice script, thanks.

I think that we are numerous to wonder which packages have to be rebuilt
after a USE flag change: For instance, if a user adds "gtk2" to his USE
flags, applications that support it will only use it after their next
update, whereas he may want to recompile this apps right now.

So my point is that your program could be even more useful if it could
show only diffs on flags that appear in the IUSE variable from their
ebuild. This would be a nice answer to the "what should I recompile?"
question.


Here are a few other ideas of possible improvements:

 * a few options: --cflags-only (-c), --useflags-only (-u), etc.

 * integration into "qpkg" (as yet another "Information Selection"
option). I know "qpkg" is still a bash script, but I think there are
plans for a python version, am I wrong?

 * taking ebuilds cflags filters into account. (Because if you go from
"-O2" to "-O3" in make.conf, and then wonder what packages have to be
recompiled for optimisation, those which filter "-O3" to "-O2" should
not be listed.)


Having said that, I won't blame you if you don't want to implement my
suggestions. I'm not a python programmer myself, and I really don't know
how hard it would be. :)

Well, I got the afternoon off, so I sat down and skimmed the original
qpkg code. Not quite understanding it, I wrote a Python version. It
mostly uses the portage core to do the work, and is therefore quite
simple. My unscientific tests shows it does some tastks slower, but some
up to 4 times faster than the bash script. All functionality of qpkg
have not been implemented yet, but It will if interest is shown.

Oh, and a link:

Oops, found a quite embarassing bug. When searching for the owner of a 
file, only every other file in the /var/db/pkg tree will be matched 
against. Well, It was only a test-release anyways. Well, if there is 
anyone out there who actually decides to est the thing, all you need to 
do is remove on of the two

line = contentsFile.readline()

and it will work properly.

I'd like to test it but I just get a 404 error.

If you can't upload it anywhere again could you please mail it to me
offlist?

Thanks,
Michael
