Get revisions affecting a file?

[Michael Gliwinski]

Hello All,

I've tried a couple of approaches and searched around for some info but didn't 
find anything relevant.

Basically what I'm trying to do is to get dates of most recent revision where 
a specific file/set of files were changed (added/modified).  Is there an easy 
way to do this using bzrlib?

My most recent attempt was to use the bzrlib.log.Logger, sth like:

from bzrlib.workingtree import WorkingTree
from bzrlib.log import Logger, make_log_request_dict
from bzrlib.tests.test_log import LogCatcher

wt = WorkingTree.open_containing('.')[0]
wt.lock_read()

try:
    for filename in some_set_of_files:
        lc = LogCatcher()
        Logger(wt.branch, make_log_request_dict(
            specific_fileids=wt.path2id(filename),
            limit=1,
            )).show(lc)
...

and then accessing `lc.revisions[0].rev.timestamp` for each file.  However 
that does not seem to work (lc.revisions is empty).  (It was also very slow, 
especially in loops like `for revs in log_rev_iterator` in bzrlib.log, which 
made me think that maybe it's not the right approach)

Is there a better/any way to do this?
