Bugzilla Bug 188678

several core (and not so core) ebuilds have a KEYWORDS entry like (as copied
from sys-libs/glibc-2.5-r4)

KEYWORDS="-* alpha amd64 arm hppa ia64 mips ppc ppc64 ~s390 sh sparc x86"

so that all supported architectures had to be unmasked explicitly, but the
logic used in equery's _get_mask_status gets confused by the use of "-*" and
indicates the package is otherwise keyword masked


Reproducible: Always

Steps to Reproduce:
1. using "amd64" or "x86" (as an example, but ~amd64 or others could be used as
well with different packages)
2. equery -N list | grep glibc
3. look at the MASK status (second field in square brackets)

Actual Results:  
$ equery -N list | grep glibc
[I--] [ -] sys-libs/glibc-2.5-r4 (2.2)

Expected Results:  
$ ./equery -N list | grep glibc
[I--] [  ] sys-libs/glibc-2.5-r4 (2.2)

present in both "amd64" and "~amd64" as well as the HEAD of the svn version

Created an attachment (id=127920) [details]
a patch to HEAD in svn (currently version 431) with a fix 

tested in "amd64", but most likely working for all other ARCH.

a more complete patch should ideally also invert the order of the "-*" check so
that it is clear that it is used as a last resource.

the construction with "pkgmask = pkmask + 0" is not really doing anything but
was added as it helped keep the change minimal and was self documenting but
could be replaced with some refactored logic and some comments instead for code
efficiency

Created an attachment (id=127921) [details]
a patch to the stable amd64 version (based on 0.2.3-r1) with a slightly
refactored logic

tested in "amd64" and with slight modifications (a patch name change since the
epatch uses ${PV} to keep consistency with what is used in 0.2.3-r1) also in
"~amd64"

gentoolkit-0.2.4_pre7 still affected by this bug,

these problem was apparently reported in bug 121220 for gentoolkit-0.2.1

Created an attachment (id=131030) [details]
if package is marked stable, skip looking for masking hints

applies against current HEAD in svn (version 440) and also to current unstable
package: gentoolkit-0.2.4_pre7
