[jira] [Comment Edited] (TS-871) Subversion (1.7) with serf fails
with ATS in forward and reverse proxy mode
[ https://issues.apache.org/jira/browse/TS-871?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13492234#comment-13492234 ]

--------------------------------------------------------
I took a look at the patch Leif had attached here. It did not apply cleanly so I worked through the issues. In the process I removed some unnecessary whitespace changes and a change of a variable to a static that don't really seem to be related to this issue. I'm attaching this updated patch as TS-871-20121107.diff.
This patch is able to function with Subversion 1.7 using Neon. However it will not work with Subversion 1.8 which can only use serf (and probably won't work with Subversion clients using serf in general though I haven't tested that).
In verifying that the patch works I modified Subversion's test suite to run through a forward TS. All tests pass (again with 1.7 using neon).
Now that I've looked at the code I can make one big observation. TS (without any patch) assumes that only POST and PUT can have request bodies. It also rejects any method it does not know e.g. REPORT.
It's not clear what the problem is with serf but for some reason the REPORT response body gets cut off when I do a checkout. It's cut off in both the response back to TS and to the Subversion client. So it'll take some more digging to understand what the problem is. It's made more complicated by the fact that 1.8 is using pipelining.
