[v13,0/9] set-head/fetch remote/HEAD updates

Message

Bence Ferdinandy Nov. 18, 2024, 3:09 p.m. UTC

This iteration handles the special case when the previous HEAD was detached.
This case is now specifically printed by both remote set-head -a and fetch.
There were also some small cleanups in commit messages and unintended
formattings.

Although the patches themselves are versioned:

- 2/9 is completely new (the above uncovered a discrepancy between backends)
- 3/9 had smaller changes to accomodate this
- 5/9 and 8/9 needed more substantial changes


Bence Ferdinandy (9):
  t/t5505-remote: set default branch to main
  refs: standardize output of refs_read_symbolic_ref
  refs: atomically record overwritten ref in update_symref
  remote set-head: refactor for readability
  remote set-head: better output for --auto
  refs: add TRANSACTION_CREATE_EXISTS error
  refs: add create_only option to refs_update_symref_extended
  fetch: set remote/HEAD if it does not exist
  fetch set_head: handle mirrored bare repositories
