836433 - mock-init brings in gcc45_0moz3 package via gcc dependency

Status: RESOLVED FIXED

(Release Engineering :: General, defect)

Description

[John Hopkins (:jhopkins)]

The mock-init step installs several packages including system gcc which in turn brings in the Mozilla gcc45_0moz3 package.
We should either:
a) stop installing system gcc during mock-init.
b) satisfy gcc's dependency explicitly to avoid bringing in gcc45_0moz3.

The system gcc may be used for a build bootstrapping operation (this has not been confirmed) so I would consider option (a) a bit more risky than option (b).

The root issue is the gcc45_0moz3 RPM package lists 'provides' of libraries which it only installs privately (in /tools/gcc-4.5-0moz3/lib/...).

gcc45_0moz3 is still being installed during mock-init which I believe is due to the yum cache holding on to package and dependency info.
I'll check back tomorrow and see whether it is cleared up.

Checked in a change to $repoflag to trigger a yum-clean-expire-cache run.  http://hg.mozilla.org/build/puppet/rev/a0b71b1ab3a9

(thanks to :rail for pointing out this mechanism)

Mock has its own yum cache which needs to be cleared.  This patch adds a mechanism to do that.

This patch also reverts patch 710285 which didn't resolve the issue.
Ran with this patch in staging and mock-init no longer brings in gcc45_0moz[34]

Confirmed that gcc45_0moz3 was not installed in build http://buildbot-master49.srv.releng.scl3.mozilla.com:8001/builders/Thunderbird%20comm-aurora%20linux%20l10n%20nightly/builds/1392/steps/mock-init/logs/stdio
