Bug Description

It seems that if the site's directories and files already exist on the remote server, bzr-upload fails with an unhandled error.

$ bzr -Derror upload --remember
FTP <email address hidden> password:
No uploaded revision id found, switching to full upload
bzr: ERROR: bzrlib.errors.FileExists: File exists: '/Foo': 550 /Foo: Access is denied.

I think the error handling has changed a bit since 2008, but the problem continues more or less the same. Uploading a working tree to an sftp location fails if that location already exists. For example:

I first created a "testfolder" folder on my server. Then:
bzr upload -v sftp://<email address hidden>/testfolder
<email address hidden>'s password:
No uploaded revision id found, switching to full upload
bzr: ERROR: File already exists

If I then issue:
bzr upload -v sftp://<email address hidden>/anothertestfolder
(where anothertestfolder doesn't exists before running the bzr command)
then everything works as expected.

I think the problem comes from a call to transport.ensure_base() from the upload plugin's upload_full_tree() function (line 227). Looks like ensure_base() returns errors that should be handled somehow, I'll see if I can work out a patch...

Better late than never, if someone still falls here, I made a little patch for /usr/lib/pythonX.X/dist-packages/bzrlib/transport/

The patch simply checks if the directory exists before trying to create it. It might be solved in recent bzr code, but on my debian testing the problem is (was) still there.

Actually this bug is in bzrlib itself, not in the upload plugin...

This is a bug in bzr-upload, not. bzrlib.mkdir() is supposed to create the directory, it's an error if that directory already exists and bzrlib properly raises an exception in that case.

It's a bug in bzr-upload that it doesn't check if the directory doesn't exist before it tries to create it, or handles the exception.
