Re: svnlook_tests.py 12 failing on trunk and 1.6.x over ra_serf and ra_neon

The test in question (svnlook_tests.py 12 "test 'svnlook * -t'")
creates this pre-commit hook:


Which wraps the "real" Pyhthon hook:

import sys,os,subprocess

fp = open(os.path.join(sys.argv[1], 'hooks.log'), 'wb')
def output_command(fp, cmd, opt):
  command = [svnlook_bin, cmd, '-t', sys.argv[2], sys.argv[1]] + opt
  process = subprocess.Popen(command, stdin=subprocess.PIPE,
stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=False)
  (output, errors) = process.communicate()
  status = process.returncode
  return status

for (svnlook_cmd, svnlook_opt) in [('changed', ''), ('dirs-changed', '')]:
  output_command(fp, svnlook_cmd, svnlook_opt.split(' '))

You'll notice that that the hook uses the svnlook binary from the
build we are testing.

This test passed for me over ra_local and ra_svn, but with ra_neon and
ra_serf, the 'hooks.log' file was empty after the test commits a
change. This causes the test to fail because it checks the contents
of 'hooks.log' after the commit and seeing nothing thinks that svnlook
isn't working.

So something wasn't working between Apache, the batch wrapper, the
python hook, and svnlook.exe.

Expanding a bit on what I said at the start: I built Apache myself
(2.2.10) and have the executable built by the InstallBin target
installed as a Windows Service. The test fails when going against
that. Starting httpd.exe manually from the command line, and using
the same conf file, it passes.
