[v2,0/4] Fix use of uninitialized hash algorithms

Message

Junio C Hamano May 13, 2024, 7:21 p.m. UTC

The series adds an escape hatch to "the default hash algorithm is
no longer SHA-1; it is an error to rely on the default" by
introducing an undocumented GIT_TEST_DEFAULT_HASH_IS_SHA1=1
environment variable that users can set after reporting an failure
they saw to us.

We can see that Patrick's two fixes to patch-id and hash-object
corrects the breakage as the series progresses.

Junio C Hamano (2):
  setup: add an escape hatch for "no more default hash algorithm" change
  t1517: test commands that are designed to be run outside repository

Patrick Steinhardt (2):
  builtin/patch-id: fix uninitialized hash function
  builtin/hash-object: fix uninitialized hash function
