New submission from Jason R. Coombs <[email protected]>:
Using Windows 7 32-bit, and /branches/p...@79802.
When I run the test_tarfile from the regrtest script, often the first run will
succeed and subsequent runs will fail (though sometimes a first run will fail
and rarely a subsequent run will succeed). It appears to be a timing issue. The
output from a failed attempt is included below.
Passing -v to the regrtest script prevents the failure from occurring. Also
disabling test_extract_hardlink test prevents the failure from occurring in
most cases. I found that enabling pdb and setting a trace in
test_extract_hardlink prevented the error from occurring. I also attempted
closing the tarfile explicitly (including in a finally block) and putting
time.sleep(1) at the beginning or end of that test, but that seemed to have no
effect.
I am beginning to suspect that this problem is related to an indexer or malware
scanner on the system checking the file after it's created, causing it to be
locked at the time it's scheduled to be deleted.
