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

 



this covers a few cases of direct filesystem access to the ref database in
tests.

v4:

 * fix stack OOB read due to missing array terminator.

Han-Wen Nienhuys (8):
  test-ref-store: remove force-create argument for create-reflog
  test-ref-store: parse symbolic flag constants
  test-ref-store: plug memory leak in cmd_delete_refs
  refs: update comment.
  refs: introduce REF_SKIP_OID_VERIFICATION flag
  refs: introduce REF_SKIP_REFNAME_VERIFICATION flag
  t1430: remove refs using test-tool
  t1430: create valid symrefs using test-helper
