[Zope-dev] zopectl start not working on Mac OS X

[Jim Roepcke]

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

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

> 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.
