source: tailor/vcpx/tests/darcs.py @ 1179

Revision 1179, 12.7 KB checked in by lele@…, 7 years ago (diff)

Split the monolithic repository.py into smaller units
The repository subclass of each backend is now in the same unit that
implements its working dir, under the vcpx.repository subpackage.
This has several advantages: the obvious of keeping related code closer
and the ability of lazy load only the needed unit, as it was already done
for the working dir subclasses.
