[PATCH] Remove redundant url-encoding added in r917523

From: vijay <vijay_at_collab.net>
Date: Thu, 24 Mar 2011 16:11:31 +0530


This patch adds a testcase for the regression triggered by r917523 and
fixes it.

The revision r917523 do some url-encodings to the paths and uris in

$svn log -r917523
r917523 | kameshj | 2010-03-01 19:18:01 +0530 (Mon, 01 Mar 2010) | 26 lines

With the below apache configuration(See the <space> character "/svn 1/").

<Location "/svn 1/">
   DAV svn
   SVNParentPath /repositories
<Location "/svn 2/">
   DAV svn
   SVNParentPath /repositories-slave
   SVNMasterURI "http://localhost/svn 1"

Write through proxy is *not* happening and commit happens *directly*
inside the slave.

* subversion/mod_dav_svn/mirror.c
   (proxy_request_fixup): URI encode the to be proxied file name.
   (dav_svn__proxy_request_fixup): r->unparsed_uri is in url encoded
form while
     root_dir is not in encoded form. So use r->uri to compare with
   (dav_svn__location_in_filter): URL Encode the 'find & replace' urls as
     the request body has it in url encoded format.
   (dav_svn__location_header_filter): Encode the master_uri as the
response from
     master has the Location header url encoded already. Set the
outgoing Location
     header url encoded.
   (dav_svn__location_body_filter): URL Encode the 'find & replace' urls as
     the response body has it in url encoded format.


There is one extra url encoding in
mirror.c:dav_svn__location_header_filter() which encodes the Location
header response from master second time, which in turn causes failure
while committing a path to slave repo which has space in it. The space
in the path is encoded as "%20" first time, again it is encoded as
"%2520", which fails with error "File not found" while committing.

I have added a testcase for this issue in
subversion/tests/cmdline/dav-mirror-autocheck.sh. I have just used the
existing master and slave repo setup for my new test case.

I have a plan of introducing "davmirrorautocheck" which we can execute
like "make davmirrorautocheck", it will run all our python test suites
via write-through proxy. All commits to the slave will be proxied to the
master repo. The master repo's post commit hook will sync every commit
to the slave repo. We can check whether slave and master repo are in
sync in 'run_and_verify_commit'.
We can extensively test our write-through proxy by making use of all our
existing tests.

Attaching the patch and log message.

Thanks & Regards,
