bzr-svn breaks https:// urls?

[Steve Langasek]

Binary package hint: bzr-svn

Recently, bzr has been failing when trying to do checkouts of https:// urls:

$ bzr co https://code.launchpad.net/~hardware-certification/checkbox/trunk
bzr: ERROR: A Subversion remote access command failed: Server sent unexpected return value (405 Method Not Allowed) in response to OPTIONS request for 'https://code.launchpad.net/~hardware-certification/checkbox/trunk'
$

I initially thought it was user error, but I'm seeing this with package Vcs-Bzr values that I know used to work.

Checking out with lp: URIs works fine, but then these map to bzr+ssh instead of https anyway.

I think you have the wrong binary package, as there's nothing subversion related going on here. It should probably be just plain 'bzr'. (Updating as such.)

Also, I am unable to reproduce this on my system. Can you post apt-cache policy bzr?

bzr:
  Installed: 1.18-0ubuntu1
  Candidate: 1.18-0ubuntu1
  Version table:
 *** 1.18-0ubuntu1 0
        500 http://us.archive.ubuntu.com karmic/main Packages

Except for, er, the error message that *says* Subversion, and that removing the bzr-svn package is sufficient to correct the problem?

I think you didn't have bzr-svn installed on your system when you tried to reproduce this.

[David Tomaschik (matir)]

You're right, my apologies. I did, however, have bzr-svn installed on my system at the time I tested this. Oddly enough, my main user has no problem, but a new user gets the same message you do.

Weirdly, the bzr-svn package only registers a handler for svn+https, so it SHOULDN'T be intercepting https requests.

Again, sorry for my confusion.

[Jelmer Vernooij (jelmer)]

This is a known issue, fixed in newer versions of bzr-svn.

There is an existing transport for https:// registered that bzr-svn can also use.

Any chance of getting the newer version into Ububtu Karmic? The current version (0.6.4) still displays these problems ... :-(

[Jelmer Vernooij (jelmer)]

There is a 0.6.5 in Debian now that should work better. Any chance
this could be synced over to Karmic?

Hi Jelmer,

I don't see immediately which revision between 0.6.4 and 0.6.5
would fix this bug, but I assume it is fixed in the 0.6.5 that
you uploaded to Debian?

Thanks,

James

Does it need a feature freeze exception?

Sorry, my assessment was premature. This problem was fixed for bzr+httplib users in bzr-svn 0.6.4 but is still there for people who have pycurl installed and that has not yet been fixed for 0.6.5.

Yes, but only for tiny tiny features, I was planning to request one once
I heard back from Jelmer here.

Thanks,

Should be fixed - we now have a hack to probe for Subversion repositories using pycurl.

Fetching this URL still fails, but with a more appropriate error:

jelmer@ganieda:~/tmp$ bzr co https://code.launchpad.net/~hardware-certification/checkbox/trunk cb
bzr: ERROR: Invalid http response for https://code.launchpad.net/~hardware-certification/checkbox/trunk/.bzr/branch-format: Unable to handle http code 405: expected 200 or 404 for full response.

[Jelmer Vernooij (jelmer)]

FWIW, a workaround for this problem is uninstalling pycurl or using http+urllib:// in bzr.

[Steve Langasek (vorlon)]

Issue still appears to be present, even with bzr-svn 1.0.0-1 installed:

$ bzr co https://code.launchpad.net/~ubuntu-desktop/gnome-screensaver/ubuntu gnome-screensaver
bzr: ERROR: A Subversion remote access command failed: Server sent unexpected return value (405 Method Not Allowed) in response to OPTIONS request for 'https://code.launchpad.net/~ubuntu-desktop/gnome-screensaver/ubuntu'
$

[Jelmer Vernooij (jelmer)]

You need the trunk version of bzr-svn, the fix isn't included in the bzr-svn packages in either Debian or Ubuntu (yet).
