bzr st on a working copy is slow

[Kevin Fitch]

bzr 1.12
bzr-svn 0.5.2
Ubuntu 8.04

I have a subversion working copy, if I do bzr st on it, it will pull down stuff from the repo .. very slick. Then in the future if I do bzr st on that directory it takes 15-30 seconds.

If instead I check out the subversion repo with bzr e.g.:
bzr co svn+https://....
bzr st

It responds immediately.

The subversion server is running svn 1.3.0 (I can't get them to upgrade :( )
I checked it out with svn 1.5 (I think ... whatever is in ubuntu 8.04)

bzr checkouts contain all history locally, svn (lightweight) checkouts do not and therefore contact with the server is required to retrieve some of that information.

I don't think there's much that bzr-svn could be doing differently here.

[Matt Nordhoff (mnordhoff)]

They do contain enough information for "svn st", don't they?

[Jelmer Vernooij (jelmer)]

Yes, but the bzr API requires other stuff as well - the repository layout and file ids, for example.

[Jelmer Vernooij (jelmer)]

re-assigning this to bzr, as this is as slow on native bzr lightweight checkouts as on svn lightweight checkouts with the recent svn/bzr-foreign performance improvements.

Is this any more than just connecting to the remote machine? (establishing an ssh connection, for example)

At 'bzr st' time, we do make a connection to make sure the target branch exists, etc.

It is just connecting to the remote machine and checking for the
latest revid there.
