tagging for platformeng to see if anyone can repro a non-windows platform.

When uploading a new version of an existing file.
I always got the following message:

Could not acquire lock for key "est5rsvfknamj8y9bqldhv8tszzpfqe".

Does this happen when uploading a file under a name that nothing uses?

No, I can upload file with a brand-new name.

Can you test a bit of PHP code, e.g.:
$fp1 = fopen( <path to a file in a dir that exists>, 'a ' );
$ok1 = flock( $fp1, LOCK_SH | LOCK_NB );
$fp2 = fopen( <path to same file>, 'a ' );
$ok2 = flock( $fp2, LOCK_EX | LOCK_NB );

And look at $ok1/$ok2.

You can also test MW before and after r106935 to see if that helps.

I added following code into FSLockManager.php, and my php-errors.log shows:

[21-Dec-2011 18:10:23] $ok1: "1"
[21-Dec-2011 18:10:23] $ok2: ""

Sorry that I know almost nothing about php...

I can finally upload the file after updating to r106935.
