We are planning on shipping Zope 2.7 with the Plone 2 installer for Mac OS X. I can start a Zope instance on Mac OS X 10.2.8 using $INSTANCE_HOME/bin/runzope, but not using $INSTANCE_HOME/bin/zopectl start. I'm using Python 2.3.2 built from source, and Zope was built using: ./configure --with-python=/Applications/Plone2/Library/Software/Zope270/Python/bin/ python --prefix=/Applications/Plone2/Library/Software/Zope270/Zope --optimize make make install (note, the same thing happens whether or not i use the --optimize option) This happens with b3 and Zope-2_7-branch from today. cd $INSTANCE_HOME ./bin/zopectl start

Traceback (most recent call last): File "/Applications/Plone2/Library/Software/Zope270/Zope/lib/python/Zope/ Startup/zopectl.py", line 215, in ? main() File "/Applications/Plone2/Library/Software/Zope270/Zope/lib/python/Zope/ Startup/zopectl.py", line 198, in main c.onecmd(" ".join(options.args)) File "/Applications/Plone2/Library/Software/Zope270/Python/lib/python2.3/ cmd.py", line 210, in onecmd return func(arg) File "/Applications/Plone2/Library/Software/Zope270/Zope/lib/python/Zope/ Startup/zopectl.py", line 134, in do_start ZDCmd.do_start(self, arg) File "/Applications/Plone2/Library/Software/Zope270/Zope/lib/python/ zdaemon/zdctl.py", line 214, in do_start os.spawnvp(flag, args[0], args) File "/Applications/Plone2/Library/Software/Zope270/Python/lib/python2.3/ os.py", line 543, in spawnvp return _spawnvef(mode, file, args, None, execvp) File "/Applications/Plone2/Library/Software/Zope270/Python/lib/python2.3/ os.py", line 504, in _spawnvef wpid, sts = waitpid(pid, 0) OSError: [Errno 10] No child processes

I added code to zdctl.py to print out the environment and the command line used in os.spawnvp. It is (including some environment variables I set before running it): SOFTWARE_HOME=/Applications/Plone2/Library/Software/Zope270/Zope/lib/ python INSTANCE_HOME=/Applications/Plone2/Sites/Testing PYTHONPATH=/Applications/Plone2/Library/Software/Zope270/Zope/lib/python CLIENT_HOME=/Applications/Plone2/Sites/Testing/var ZOPE_HOME=/Applications/Plone2/Library/Software/Zope270/Zope export SOFTWARE_HOME INSTANCE_HOME PYTHONPATH CLIENT_HOME ZOPE_HOME /Applications/Plone2/Library/Software/Zope270/Python/bin/python /Applications/Plone2/Library/Software/Zope270/Zope/lib/python/zdaemon/ zdrun.py -S /Applications/Plone2/Library/Software/Zope270/Zope/lib/python/Zope/ Startup/zopeschema.xml -b 10 -d -s /Applications/Plone2/Sites/Testing/var/zopectlsock -x 0,2 -z /Applications/Plone2/Sites/Testing /Applications/Plone2/Sites/Testing/bin/runzope I get this output:

Another zrdun is already up using socket '/Applications/Plone2/Sites/Testing/var/zopectlsock': status=running now=1070998107.721581 mood=1 delay=0 backoff=0 lasttime=1070998096.551084 application=1152 manager=1141 backofflimit=10 filename='/Applications/Plone2/Sites/Testing/bin/runzope' args=['/Applications/Plone2/Sites/Testing/bin/runzope']

I've looked at the source and nothing is popping out as being obviously wrong. If you have any suggestions for ways I can debug this further I can go further on this. For now I think I'm going to have to stick with runzope... but I'd really like to be using zopectl start/stop/status instead. Jim -- Jim Roepcke Tyrell Software Corp <http://www.tyrell.com/>
