CC'ing current Liaisons:
alpha : yoswink
amd64 : welp
 hppa : jer
  ppc : dertobi123

sparc : fmccor
  x86 : opfer
Comment 4 Christian Faulhammer (RETIRED) gentoo-dev 2008-06-30 10:02:03 UTC
x86 good to go.
Comment 5 Jose Luis Rivero (yoswink) (RETIRED) gentoo-dev 2008-06-30 13:44:34 UTC
In alpha:
 - compiles just fine with several USE flags combinations
 - tests passed

Seems ok.
Comment 6 Raúl Porcel (RETIRED) gentoo-dev 2008-06-30 14:58:34 UTC
Looks okay on ia64/sparc
Comment 7 Jeroen Roovers (RETIRED) gentoo-dev 2008-06-30 16:41:21 UTC
OK for HPPA.
Comment 8 Robert Buchholz (RETIRED) gentoo-dev 2008-06-30 20:52:54 UTC
Lifting embargo, Gnome team please commit straight to stable for the arches that
Comment 9 Peter Weller (RETIRED) gentoo-dev 2008-07-01 00:45:59 UTC
Good to go on AMD64 too
Comment 10 Mart Raudsepp gentoo-dev 2008-07-01 02:14:27 UTC
The ebuild has been added to the tree.

Target keywords : "alpha amd64 arm hppa ia64 m68k ppc ppc64 s390 sh sparc x86"
Already stabled : "alpha amd64 hppa ia64 sparc x86"
Missing keywords: "arm m68k ppc ppc64 s390 sh"

CCing the remaining arches. Please stabilize.

Security@ - this is much less widespread through glib than pcre proper, so I believe "A2" status should not be an "A" at least. While glib is quite widely used, PCRE code is exposed only via the GRegex API, which is not used by many glib using packages. "B" perhaps as it's not a system package.

I also don't know what the status whiteboard should be now
Comment 11 Markus Rothe (RETIRED) gentoo-dev 2008-07-01 05:27:21 UTC
ppc64 stable
Comment 12 Robert Buchholz (RETIRED) gentoo-dev 2008-07-01 08:27:38 UTC
As for whiteboard, the question should be: Is there at least one "A" program that exposes the API to attackers -- that is, allow compilation of regular expressions from a file, or from remote. Is there one within the Gnome default set of packages that does this?
Comment 13 Mart Raudsepp gentoo-dev 2008-07-01 17:03:43 UTC
I am not aware of any, but I also don't know for sure there aren't.
There are some GRegex users around by now, but most of those in turn are probably only using it with their own match strings in sources, but some might allow the user to enter it "locally" (in the X session or so). Or there might be no such things, as I said, not sure :(
