I am currently having issues with hosting a SVN repository in Phabricator. I am considering temporarily hosting the repository outside of Phabricator, until I am able to resolve this issue.

Looking at the repository Edit Hosting options, it seems like it should be possible to host a repository outside of Phabricator and later edit it so that it is hosted by Phabricator. Probably going from Phabricator-hosted to remote and from remote to different remote is supported too?

I tried a few things and details are provided below, but, briefly, what I would like to know is:

Does Phabricator support changing the hosting of repositories after they are created?
Can they be changed in the following ways:

• Remote -> Phabricator-hosted (This is most important to me at the moment.)
• Phabricator-hosted -> Remote
• Remote -> A different remote

Are additional steps beyond changing the hosting options in the Edit Hosting page necessary? If so, what are they?

Is there anything else I should be aware of when doing this?

Here is an explanation of what I've tried so far and what has happened:

To test, I configured a remote SVN repository to work with Phabricator and everything seemed to work. I then tried editing the repository to be hosted by Phabricator, which was allowed. However, the Edit Repository page complains about this error:

Working Copy Error	Working copy /var/repo/SVNTESTTWO/ has been deleted, or is not readable by the webserver. Make this directory readable. If it has been deleted, the daemons should restore it automatically.

After waiting a little while and refreshing the page, the error goes away and the page seems to indicate that everything is all right. However, if I look at the /var/repo/SVNTESTTWO/db/revs/0 directory, it looks like this:

ls -la /var/repo/SVNTESTTWO/db/revs/0
total 4
drwxr-sr-x. 2 phd phd  15 Jan  7 10:42
drwxr-sr-x. 3 phd phd  15 Jan  7 10:42
-r--r--r--. 1 phd phd 253 Jan  7 10:42 0

There seems to be only one revision, even though the remote repository had multiple revisions. It seems like the revisions have not been fully imported into the new repository. If I check out a working copy and try svn log -v, no log info is available. Also, clicking on commits for this repository in Phabricator can cause Unhandled Exception ("CommandException") messages to appear, with error messages like this:

Command failed with error #1!
COMMAND
svn --non-interactive cat 'file:///var/repo/SVNTESTTWO/path/to/some/file/in/the/repo/@320'

STDOUT (empty)
    
STDERR svn: E160006: No such revision 320

Is there something else I need to do to make this work and have all the revisions moved to the Phabricator-hosted repository? Do I need to manually dump and load the revisions?
