[PATCHv1 0/6] Fix bug in large transactions

(reported as: git update-ref --stdin : too many open files, 2014-12-20)

First a test case is introduced to demonstrate the failure, the patches 2-6 are little refactoring and the last patch fixes the bug and also marks the bugs as resolved in the test suite.

Unfortunately this applies on top of origin/next.

Any feedback would be welcome!

Thanks, Stefan

Stefan Beller (6):
  update-ref: Test handling large transactions properly
  refs.c: remove lock_fd from struct ref_lock
  refs.c: replace write_str_in_full by write_in_full
  refs.c: Have a write_in_full_to_lock_file wrapping write_in_full
  refs.c: write to a lock file only once
  refs.c: enable large transactions
