[jira] [Commented] (SVN-1532) Switch a file to a dir: can't switch it back to the file

    [ https://issues.apache.org/jira/browse/SVN-1532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16996868#comment-16996868 ] 

Nathan Hartman commented on SVN-1532:
-------------------------------------

Not sure what that "bang!" comment on the last line of the repro script represents but I just tested with 1.13.0.

First, the reproduction script in its current form no longer exposes the original issue because 'svn switch' errors out with "E195012: Path 'f' does not share common version control ancestry with the requested switch location. Use --ignore-ancestry to disable this check."

When using '--ignore-ancestry' on both invocations of 'svn switch', the first call switches the directory to the file; the second call gives "svn: E160005: Cannot replace a directory from within" (same error message as noted above). And... it is not possible to switch back to the file.

Two different fixes have been suggested above:

(1) Several people: Open the editor on the parent rather than the node itself.

or

(2) Max Oliver Bowsher: "For exactly the same reason that you cannot checkout a file, you cannot switch a file. ... So, the 'fix' for this issue is teach switch to maintain this invariant..."

(Personally, Bowsher's idea makes more sense to me.)

> "svn switch" is able to switch a file to a directory but, having done that,
> cannot switch the directory back to the file.  When "d" is a directory and "f"
> is a file, the output is:
> + svn switch file:///home/julianfoad/tmp/svn-switch-test/repos/d f
> D  f
> A  f
> Updated to revision 1.
> + svn switch file:///home/julianfoad/tmp/svn-switch-test/repos/f f
> /home/julianfoad/src/subversion/subversion/libsvn_repos/delta.c:209:
> (apr_err=160005)
> svn: Invalid filesystem path syntax
> svn: svn_repos_dir_delta: invalid editor anchoring; at least one of the input
> paths is not a directory and there was no source entry
> {noformat}
