9 years agolock_file(): always initialize and register lock_file object
Michael Haggerty [Wed, 1 Oct 2014 10:28:13 +0000 (12:28 +0200)] 
lock_file(): always initialize and register lock_file object

The purpose of this change is to make the state diagram for
lock_file objects simpler and deterministic.

If locking fails, lock_file() sometimes leaves the lock_file object
partly initialized, but sometimes not. It sometimes registers the
object in lock_file_list, but sometimes not. This makes the state
diagram for lock_file objects effectively indeterministic and hard
to reason about. A future patch will also change the filename field
into a strbuf, which needs more involved initialization, so it will
become even more important that the state of a lock_file object is
well-defined after a failed attempt to lock.

The ambiguity doesn't currently have any ill effects, because
lock_file objects cannot be removed from the lock_file_list anyway.
But to make it easier to document and reason about the code, make
this behavior consistent: *always* initialize the lock_file object
and *always* register it in lock_file_list the first time it is
used, regardless of whether an error occurs.

While we're at it, make sure that all of the lock_file fields are
initialized to values appropriate for an unlocked object; the caller
is only responsible for making sure that on_list is set to zero before
the first time it is used.

file is deleted immediately and the lockfile object is left in a
predictable state (namely, unlocked).  Previously, the lockfile was

merge-recursive: fix copy-paste mistake

The following issue was found by scan.coverity.com (ID: 1049510),
and claimed to be likely a copy-paste mistake.

Introduced in 331a1838b (2010-07-02, Try normalizing files
to avoid delete/modify conflicts when merging), which is
quite a long time ago, so I'm rather unsure if it's of any impact
or just went unnoticed.

The line after the changed line has a comparison of 'o.len' to 'a.len',
so we should assume the lengths may be different.

I'd be happy to have a test for this bug(?) attached to
t6031-merge-recursive.sh, but I did not manage to
come up with a test in a reasonable amount of time.
