[bitbake-devel] [PATCH 1/1] fetch2/git.py: fix _latest_revision for local PREMIRROR

[Robert Yang]

- Fixed when SRCREV = "${AUTOREV}", and set BB_NO_NETWORK = "1":
$ bitbake <recipe> -ccleanall
| DEBUG: Executing python function do_cleanall
| DEBUG: Python function do_cleanall finished
| ERROR: Function failed: Network access disabled through BB_NO_NETWORK ...

- Fixed when SRCREV = "${AUTOREV}", set BB_NO_NETWORK = "1"  and use
  local PREMIRROR:
$ bitbake <recipe> -cfetchall
| DEBUG: Python function do_fetch finished
| ERROR: Function failed: Network access disabled through BB_NO_NETWORK ...

Stop running "git ls-remote" when BB_NO_NETWORK would fix the problem.
