Hi
I wonder if someone with the new Zope-Plone-LatexWiki experience can help me.
Having been enthusiastic about MathAction I tried to set it up locally on my
local computer, too, using the ZWiki and LatexWiki files on
http://page.axiom-developer.org/repository. Strangely enough Axiom is not
rendered, as the method runCommand() in axiomWrapper.py fails when run from
inside Zope. Testing the method externally either within a zope.app() or as a
standalone method, does not produce errors and works as expected.
I checked with a lot of analoguous situations, first suspecting missing access
rights, but "wrapping", for example, an executable, a segfaulting executable
or a psql script run fine, standalone or within zope as external methods.
I can boil down the error to the external method "demo.py" at the end of the
mail, which is similar to the runCommand() in axiomWrapper.py.
Zope is version 2.6.4; python used is version 2.2 and it all runs on a Debian
sarge system.
The exit codes for Popen3 when run from Zope are:
WEXITSTATUS:139
WIFEXITED: 1
Thank you for any help.
Cheers, H.P.
demo.py:
import os
from popen2 import Popen3
axiomTemplate = r""")set output algebra off
)set output tex on
)set message autoload off
)set quit unprotected
integrate(x**2,x)
)quit
"""
LatexWikiHome = '/usr/lib/zope/lib/python\
/Products/LatexWiki/Extensions/'
axTinput = open ( LatexWikiHome + 'axT.input', 'w' )
axTinput.write(axiomTemplate)
axTinput.close()
cmdLine = r'export AXIOM=/usr/lib/axiom-0.20040831;\
export PATH=$AXIOM/bin:$PATH;\
AXIOMsys < %s ' %(LatexWikiHome + 'axT.input')
def echoWorld():
""" external method calling Popen3 """
p = Popen3 (cmdLine, 1, 4096)
status = p.wait()
p.tochild.close()
out = p.fromchild.read()
p.fromchild.close()
err = ''
if p.childerr: err = p.childerr.read(); p.childerr.close()
error = os.WEXITSTATUS(status) or \
not os.WIFEXITED(status)
if not error: return\
'Output: ' + out +\
