[gentoo-dev] format of files in /var/cache/edb/dep

[gentoo-dev] format of files in /var/cache/edb/dep

[Andrew Gaffney]

I've looked around for a reference to the format of the files in 
/var/cache/edb/dep, but I can't seem to find anything. From looking at 
/var/cache/edb/dep/x11-base/xfree-4.3.0-r5, it seems that it is:

DEPEND
RDEPEND
SLOT
SRC_URI
RESTRICT
HOMEPAGE
LICENSE
DESCRIPTION
KEYWORDS
?
IUSE
?
?

Can someone verify what I have filled in and fill in my blanks? Thank you.

Well that rather depends upon which backend you're using for the portage
cache. You can't really rely upon a particular format there.

Are you serious? Why would the format of important files used by Portage change?

I was testing it earlier again my Perl dependency checker that I'm working on. 
After deleting the contents of /var/cache/edb/dep, Portage took 42s to do 
'emerge -ep xfree'. It then took 2.819s to run the same command again with the 
cache rebuilt. My program took 0.981s to do the same thing while generating 
dependency information directly from the ebuilds on the fly. Although, my 
dependency checker isn't yet as complete as Portage's.

For example, if one package has a dependency of '>=package2-2.0' and another has 
'<package2-2.3' and the newest version of package2 is 2.6, my program will 
choose to install package2-2.6.

It can currently handle USE flags, auto-USE flags, (un)masked packages, and 
virtuals (somewhat). It also saves time by not involving bash in the dependency 
process at all. Instead, it parses all the variable declarations straight out of 
the ebuild and does bash-style interpolation within the program.

Thanks. That's just what I needed. Someone also suggested to look at the end of 
ebuild.sh, which contains about the same information.

You're after the auxdbkeys list in portage.py- this is it, note that 
the flatfile cache's use the same ordering for storage-
auxdbkeys=[
'DEPEND',
'RDEPEND',
'SLOT',
'SRC_URI',
'RESTRICT',
'HOMEPAGE',
'LICENSE',
'DESCRIPTION',
'KEYWORDS',
'INHERITED',
'IUSE',
'CDEPEND',
'PDEPEND',
'PROVIDE',
'UNUSED_01',
'UNUSED_02',
'UNUSED_03',
'UNUSED_04',
'UNUSED_05',
'UNUSED_06',
'UNUSED_07',
'UNUSED_08'
]
