Hmmm. I'm still getting a failure over ra_neon:
prop_tests.py 26: test handling invalid svn:* property values
When I say I run 'make check', what I really mean is I run the
regression test suite over at least three RA layers:
make check CLEANUP=true
make svncheck CLEANUP=true
make neoncheck CLEANUP=true
make serfcheck CLEANUP=true /* Usually run this, not always */
Now, the latter two, Neon and Serf, require that I start up the httpd
server of course. I usually do that by hand, but 'make davautocheck'
should automate the process if you want.
The above failure is from 'make neoncheck'. Do you know what's causing
it? (I haven't looked into it yet, having choosen instead to
shamelessly toss the ball back into your court :-) .)
Below is the exact patch I was testing, using approximately r31143 of
trunk:
[[[
Fix "file not found" error when a merge target is a broken symbolic link.
Patch by: David O'Shea <david.oshea_at_s3group.com>
* subversion/libsvn_wc/merge.c
(svn_wc__merge_internal): Diff against detranslated file if the
target is "special".
* subversion/tests/cmdlink/merge_tests.py
(merge_broken_link): New test function.
(test_list): Call the new test function.
]]]
