bitkeeper question

[Cameron, Steve]

Hi,

I'm not sure if this is the right place
to ask.  I'm wondering about how (and if) tags
are being used for the bk://ppc.bkserver.net/linuxppc_2_4_devel
tree.

I would like to be able to clone and
export a "known" state (lets call it "state_1")
of the tree, then later be able to get another
known state of the tree ("state_2") and have
(or be able to generate) a patch that can take
me from "state_1" to "state_2".

I guess I can do this by doing

bk export -r state_1 state_1

then, later after some "bk pulls" have been done,

bk export -r state_2 state_2

provided that "state_1" and "state_2" are
the two tags.

But, i don't know what the tags are that people
are using, if any.  Or am I grossly misunderstanding
bitkeeper?  Is it up to me to tag my own clone of
the repository whenever I want, and just use "bk pull"
to get "the latest stuff", whatever that might be?
If there is a regular tagging scheme already in use,
I think I'd rather just use those existing tags, as
long as I can stay reasonably up to date that way.

Thanks for any info.

The only tags on that repository are the kernel.org tags.  IE:
bk export -rv2.4.18
Will get you kernel.org as of 2.4.18.   If you do some looking w/ bk
changes, you can see when that was merged into the repository, and
export that changeset.

You might be grossly misunderstanding bk, let's see if this makes any
sense...

Every time you do a commit, you've created the equivalent of a CVS
tag.  It's just a number, but it is a "known state" of the entire
repository, not just the files you checked in.  You can add a
non-numeric tag to some versions for convenience, but a non-numeric
tag is not required to do the kind of operations you're looking for.

The easiest way to export a patch is to find the two changeset numbers
you're interested in and run:

bk export -tpatch -r<rev1,rev2> > ../patchfile

Does that help or did I grossly misunderstand you? :)
