Bug#555804: pu, opu: package fam/2.7.0-13.3, fam/2.7.0.12

[Chuan-kai Lin-2]

Package: release.debian.org
Severity: normal
User: release.debian.org@...
Usertags: pu, opu

I propose updating the fam packages in stable (lenny) and oldstable
(etch) to fix the long-standing bug of occasional 100% CPU usage.

The fix is very simple: linking famd with librt and libpthread.  I am
not familiar with the inner workings of this fix, but it is proposed by
Wil Evers on the fam mailing list [1].  Since I introduced this fix in
fam 2.7.0-14 in July 2009, there have been no reports of either this bug
reoccurring, or regressions caused by this fix.

Since there are still some stable and oldstable users who would like to
see this bug fixed [2], I would like the release team to consider
accepting this fix in both stable and oldstable.  Attached are the
incremental patches from current fam sources in stable and oldstable; I
have tested the patches in the appropriate chroot environments and they
both build fine.

Please let me know if you would like further information.

wow, it didn't even make it into the bug tracker.  Please, pretty please,
get that issue fixed in stable and oldstable.  The argument in Wil's mail
seems convincing.

Kind regards,

I take that as a GO permission to upload, yes?
