should prompt for usernames during HTTP Basic/Digest auth

Bug Description

if there is no username in the URL and the remote server sends a 401, bzr currently just prints the error it received back. It would be nice if it could prompt the user for a username rather than printing the (confusing) error message.

svn+ is just a workaround to bypass the standard http implementation in bzr. Bzr's standard http implementation should handle the 401 response properly and prompt for a password, so reassigning this to bzr.

I doubt bzr is going to look for the svn cached username/password
in, nor write the password it got into that cache. If so, having
bzr handle this itself is not good.

http:// is handled by bzr itself, so this can only be handled in bzr itself.

bzr-svn can expose the credentials in the subversion cache to bzr and likewise, bzr can expose the credentials entered on the command-line to bzr-svn.

Should we perhaps increase the severity of this bug? There are 8 dupes reported already.

While the number of dupes can be seen as a launchpad bug, it is indeed a sign that we should fix it rather sooner than later.

As discussed on IRC with jelmer, the solution seems to be that bzr should access the svn credentials and be able to give them back to bzr-svn so that it fails (more gracefully) when probing the server and let bzr-svn probe successfully.

For now, bzr-svn can't probe because the bzr probe aborts.

Work has begin at lp:~bzr/bzr/pluggable-credential-stores. The idea is to allow bzr-svn to plug a credential store enabling bzr to access svn credentials.

I encountered this bug today and found the solution to be prepending svn+ to the url.

However, since you still won't be able to commit without credentials, won't this only be a solution for reading the repo and not committing to it?

Anyway, when I try to commit I get the error:

C:\temp\test-repo\trunk>bzr commit -m "Testing bzr svn integration"
The svn+ syntax is deprecated, use
ss-001/grant/trunk instead.

Just to add another vote for fixing this asap, this bug is really important to me, since I was hoping to switch from git, but cannot without https auth cred.

sorry comment was out of line, i should of taken time to see that it's marked as high priority and triaged already.
i'd take it back if I could! (perhaps a delete/undo comment feature would be good in launchpad?)

sorry guys!

Changing status to 'in progress' as it better reflects the actual state of affairs. There is progress, even if too slow for everybody taste, sorry for that.

Jelmer, I think bzr now provides enough support for bzr-svn to provide the credentials to bzr, is there something I can do to help here ?

The bug is still open as I want to have a working svn solution for it and also reports a more user-friendly error (along the lines of: connection error, check your credentials instead of the 401 unexpected error).
