[PATCH 02/15] refs.c: return error instead of dying when locking fails during transaction

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

 



commit e193c10fc4f9274d1e751cfcdcc4507818e8d498 upstream.

Change lock_ref_sha1_basic to return an error instead of dying when
we fail to lock a file during a transaction.
This function is only called from transaction_commit() and it knows how
to handle these failures.
