You can do some strange and crazy hacks, if nothing else: $ FID=`sha1sum myfile` $ monotone automate ancestors `cat MT/revision` \ | monotone automate toposort [EMAIL PROTECTED] | tac \ | while read REV; do if monotone cat revision $REV | grep -q $FID; then echo "$FID was touched in rev $REV" fi done This will print one line for each revision that either created or removed a file with the given hash, in some plausible (history respecting) order. > >>It may be useful to go from a hash to a list of all revisions which > >>contain it (together with the filenames, since the same contents may > >>be in files with different names, of course), but I don't think > > > > I agree, that would be extremely useful. > > All we need is something like an SQL database; then we could have a > table: (filename, hash, revision).

History searching is, in general, an interesting feature for a VCS to have -- searching for old paths, searching for old text (history-sensitive grep), grepping through changelogs, etc. Mercurial and I guess FastCST both make some interesting efforts in this area; I would certainly not object if people wanted to add similar features to Monotone, they're rather handy. -- Nathaniel -- "But suppose I am not willing to claim that.
