problem with paths with spaces with 12.04 client with 14.04 server
source package: subversion
bin package: libapache2-mod-svn
The problem shows up with libapache2-mod-svn 1.8.8-1ubuntu3 on the current 14.04 (amd64 though that doesn't matter). It showed up in 1.7.14 already.
The problem is an interoperability problem with subversion clients prior to 1.7.x. Typically, ubuntu 12.04 clients (1.6.17) are affected by that bug. That means that anybody upgrading their server from 12.04 to 14.04 are potentially going to be affected (unless they upgrade their clients beforehand)..
There's a related bug with the subversion server coming with 13.10 which I'll raise shortly.
Newer clients (1.7 and above) are not affected even with "SVNAdvertiseV2
How to reproduce:
On a 14.04 server (as root),
apt-get install apache2 subversion libapache2-mod-svn
svnadmin create /srv/svn
chown -R www-data: /srv/svn
cat > /etc/apache2/
service apache2 restart
On a 12.04 client:
svn co http://
mkdir -p 'A B/C'
echo test > 'A B/C/x'
svn add 'A B'
svn ci -m m1
svn log 'A B/C/x'
That svn log command will fail with:
svn: Unable to parse URL '/svn/A B/C/x'
A commit of a change on that "x" file will fail as well:
echo test >> 'A B/C/x'
svn ci -m m2
When using svn log --config-option servers:
Sending request headers:
PROPFIND /svn/A%20B/C/x HTTP/1.1
User-Agent: SVN/1.6.17 (r1128011) neon/0.29.6
[status-line] < HTTP/1.1 207 Multi-Status
[<?xml version="1.0" encoding="utf-8"?>
<D:multistatus xmlns:D="DAV:" xmlns:ns1="http://
<D:response xmlns:lp1="DAV:" xmlns:lp2="http://
<D:status>HTTP/1.1 200 OK</D:status>
While the problem with 13.10 (1.7.9) was too much URI encoding (space turned to %20 itself turned into %2520), it looks like in this case there's not enough encoding (href being /svn/A B/C/x instead of /svn/A%20B/C/x above).
It is really a bug because even < and > are not encoded. The reason why newer clients work is because they send different HTTP requests (OPTIONS, REPORT and no PROPFIND even with V2 disabled).
On 12.04, one can work around the problem by upgrading svn from the "svn" ppa (svn 1.7.9), but note that it breaks rapidsvn (segfault) and possibly other tools linking to libsvn.
As show above, space is not the only character causing problem.
