In the last few days, I committed an extra criterion to help determine
'changedness' of a file: libsvn_wc also considers the size of the file
at hand. So, now we do not only depend on the timestamp any more. If a
file changes in size (but not in time), svn will detect it's possibly
In our test-suite all but 2 tests change the sizes of the files
involved in the test. That means that all (except these 2) tests don't
have to depend on the timestamp to complete successfully.
I added (locally) a test to svn_sleep_for_timestamps() to check an
environment variable whether or not to sleep for stamps. When running
the test suite with that variable set to the right value,
basic_tests.py took 24seconds.
Recently lgo added parellel (?) execution of tests. Tests run in
parellel also take 24seconds.
I'd like to change our test suite to not sleep for timestamps except
for a specified number of tests. Currently the specified tests would
be the ones which fail without sleeping. That way, we won't need the
parellelized feature (lgo prefers to rip that).
Additional benefit of not-sleeping versus parellelizing is that the
on-disk space-requirements stay the same as they currently are. This
could be important for execution on RAM disks.
