I have recompiled with the patch,
When trying to commit to the slave, the client receive:
"Commit failed (details follow):
Server sent unexpected return value (500 Internal Server Error) in response to
MKACTIVITY request for '/!svn/act/12aad366-69cf-2b48-9303-bfb1220af919'
And now the error is logged in the VirtualHost error log (as defined)
instead of the main apache error log.
[Wed Dec 12 16:47:33 2012] [error] [client 10.0.2.15] (125009)APR does
not understand this error code: Invalid URI segment
'!svn/act/779db2c6-6390-e147-a8be-cc8434b0919f' in slave fixup
As i understand it will be best to switch from using root dir to
something like "/svn".
Thanks for your help.
