I'm sorry, I completely managed to miss this email too, somehow.
Guess things are a little better now than back in August...

else on the list will take my questions as being directed at them too

Interesting idea. I'm not quite sure how useful it is in monotone's
case, though, because of some other architectural differences:
-- for databases, you can just run a "push" to be sure; this is
always safe and painless (it never requires any merging, unlike,
-- for working directories, you can just run "diff" or "status" to
see if there are any local changes.
These pre-existing commands seem to handle the "bk superset" use case
pretty naturally, I think?

Yep, it'd be nice. On the todo; I keep suggesting it would be a nice
project for someone, but no-one's taken me up on it yet...

'ls tags', though there's currently no way to restrict it to a branch.

Agreed. Stuck this in the newly cleaned up bug tracker:

Hmm, interesting. The code change for this would be a bit complex; do
you have any use case in mind in particular?
(Remember again that, unlike BK IIUC, "push" and "pull" in monotone
are completely safe and completely separate from merging.)

Agreed. I'm not sure what a good interface for this would be, though.

Honestly, the easiest way to do this right now is "cat MT/revision"
:-). While this is impure and all, it sort of lowers the urgency of
such a thing...
Perhaps the new "automate" interface should contain basic revision

We have this now: explicit_merge.

If you still have the information, I'm curious; though things have
changed enough it may not still apply...

merge-into-working-directory is a TODO item; that will give you what
For most people, it seems more common to just do the merge, and then
if there are any problems with it commit a fixup revision as a child,
before sync'ing. With some strategic use of when you choose to sync,
you can get the effect of a temporary database -- before running a
merge, push your changes out. Now, until your next commit/merge,
you can treat your main database as a temporary database, it contains
nothing irreplaceable. Run your merge, and make sure things look good
before pushing them out. If they don't look good, and you want to
just scratch that whole merge altogether, then just delete your
database and re-fetch from the server.

Thanks for you feedback and kind words! Hope we haven't scared you
off by misplacing your message...

Hmm, odd. I've filed a report with the savannah admins about it.
