From 7d7ee630f1c65e7dd234f945edf5e3b3bcb0fc30 Mon Sep 17 00:00:00 2001 From: Mark Hatle Date: Tue, 15 Jan 2019 16:31:35 -0500 Subject: gitsm.py: revise unpack Greatly simply the unpack rule by copying the general functionality of update_submodules as unpack_submodules. This will recursively construct a set of urls and unpack them using the standard system behaviors. The overall code may be slightly bigger, but this ensures that all of the standard locks are inplace, ensuring the code doesn't change out from under the unpack function. (This could have happened before due to using 'cp' instead of further unpacks on submodules. This may still happen in shallow clones.)
