1132458 - Improve mozharness l10n setup time

Status: RESOLVED FIXED

(Release Engineering :: Applications: MozharnessCore, defect)

Description

[Massimo Gervasini [:massimo]]

A full run of desktop repacks, 5 locales, takes about 48 minutes to complete (on windows). About 20 minutes are spent by setting up the environment: deleting old directories, updating hg, ... 

We should improve the set up time, for example we could use mozharness to download the initial en_US binary, skipping the first mach configure/make wget-en-US run.

We spend few minutes re-cloning everything because PurgeMixin.clobber(self, always_clobber_dirs=[objdir]) deletes the build/ directory too.

This patch remove the dependency of DesktopSingleLocale from PurgeMixin, and deletes only the directories that need to be deleted.

-----------------------------------------------------------------

I'll trust in you to know the bits that should be and shouldn't be deleted each time.

side effect of this is we lose the ability to do a full clobber (c['force_clobber']) and developer_mode though I don't think that really matters at this point and if we can safely speed this up, \o/
