            Bug ID: 36358
           Summary: .rtf files from test suite cause svn failures on
                    buildbot
           Product: new-bugs
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: seurer at linux.vnet.ibm.com
                CC: llvm-bugs at lists.llvm.org

I updated one of the powerpc64 lnt buildbot machines to a new OS release and
the buildbot started failing every run when it tries to check out the test
suite.

The checkout will run for a while then always fails like this:

/usr/bin/svn checkout --non-interactive --no-auth-cache --revision 323463
http://llvm.org/svn/llvm-project/test-suite/trunk@323463 test/test-suite
 in dir /home/buildbots/ppc64be-clang-lnt-test/clang-ppc64be-lnt (timeout 1200
secs)
...lots of files checked out...
svn: E000104: Error running context: Connection reset by peer


I tried checking out the test suite by hand on the same machine with the same
results.  If I restart the checkout (or do an svn update) it will run a bit
longer then fail.  Eventually I figured out that 3 files were causing the
problem:

MultiSource/Applications/ClamAV/inputs/rtf-test/Doc1.rtf
MultiSource/Applications/ClamAV/inputs/rtf-test/docCLAMexe.rtf
MultiSource/Applications/ClamAV/inputs/rtf-test/rtf1.rtf


I tried on other powerpc64 machines (various distros and BE/LE) and it works on
all of them UNLESS they are using the latest version of svn, version 1.9.7
(r1800392).  The latest svn version that works on a powerpc64 machine was
1.9.5.
It also will fail on a mac running svn 1.9.4.

svn 1.9.7 on a powerpc64 BE machine (or on the mac with svn 1.9.4) always
eventually gives the "Connection reset by peer".  With svn 1.9.7 on a powerpc64
LE machine it eventually will hang.

Note that at least one of these files is flagged as suspicious by AV:

If I use https instead of http to check them out they succeed so we could
update  the buildbot python to use https.  However, given the AV thing above
that makes me nervous.
