[PATCH 0/2] Another reroll of sb/submodule-init

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



* squashed the fixes from Johannes Sixt to unbreak Windows tests.
  (I had encoding issues; so I manually integrated the changes)
* fixed memleaks
* the base to apply did not change (ee30f17805f51d37 Merge branch
'sb/submodule-path-misc-bugs' into sb/submodule-init)

Thanks,
Stefan
