cset #'s stable?

Are changeset #'s stable?

I'm specifically looking at linux-2.5/net/sunrpc/clnt.c, "rev 1.1153.63.[123]" which I recorded earlier as 1.1153.48.[123].

/fc

No, they are not. The key, however, is stable (bk changes -k -r<rev>, for example).

Changeset numbers are subject to change when you merge in other changesets which depend on earlier changesets. So older changeset numbers tend to be more stable compared to newer changeset numbers, and changeset numbers won't change unless you have done a pull (or someone else has done a push) to your repository.

This is in the X-BK-ChangeSetKey: header of the mails sent to the mailing lists.

FWIW, it's easy to go back and forth as well, bash (pure sh?) functions to do it:
REVTOKEY() {
if [ -z "$1" ]; then
echo "Usage: REVTOKEY revision-number"
else
if [ ! -f ChangeSet -a ! -f SCCS/s.ChangeSet ]; then
echo "Must be run from the base of a BitKeeper repositor
y"
else
echo -n "The key is: "
bk prs -r$1 -hnd:KEY: ChangeSet
fi
fi
}

KEYTOREV() {
if [ -z "$1" ]; then
echo "Usage: KEYTOREV key"
else
if [ ! -f ChangeSet -a ! -f SCCS/s.ChangeSet ]; then
echo "Must be run from the base of a BitKeeper repositor
y"
else
echo -n "The key is: "
bk prs -r$1 -hnd:REV: ChangeSet
fi
fi
}

Nice. I believe current bk lets you do bk changes -k -r<rev> to get key from ChangeSet file (identical to bk prs -r -hnd:Key ChangeSet), and echo key | bk key2rev ChangeSet to convert back. Not much simpler, but a little ;-)

In general, we're moving towards a BK version where keys (internal revisions, sort of like mail message id's) are useable anywhere a rev is useable.

One place we'll be using this is on BK/Web so that you guys can have URLs that don't change out from underneath you.

We should fix that at the same time that we turn on the GNU patch server so you can get any changeset as a patch. The dual T1's are due in at the end of this month.

There may be some delay, I'm away dealing with family stuff that is way higher in priority than this but I'll try and get someone else to do it if it takes longer than the end of the month before I'm back.
