[wingide-users] Problems with wingdbstub.SuspendDebugPeter.Frey@haufe.de Peter.Frey at haufe.de

Hi, I am using WingIDE 1.1.9-1 with Python 2.2.2 (with largefile support compiled in) and Zope 2.6.1 for debugging on a Suse Linux 8.1 desktop system. My problem is with startup performance when debugging my scripts that interface to the Zope runtime. It looks like it is caused by over 600 modules loaded at startup time of my script. The script runs as a batch process, i.e. not inside a Zope http request. To speed up this process I tried to implement the tip found in the Wing IDE manual (HTML) in section 6.15.7 "Full Control via Debug API" as follows: global DEBUG DEBUG = 1 if DEBUG: import wingdbstub wingdbstub.debugger.SuspendDebug() # suspend debugger to speed up startup time for Zope environment import sys, traceback import os, os.path import re import time import getopt, glob import Zope try: print "% starting up Zope environment ..." Zope.startup() # added for Zope 2.6 except: etype, value, tb = sys.exc_info() print "*** failed to do Zope 2.6 style initialisation" print "Exception %s: %s" % (etype, value) traceback.print_tb(tb) sys.exit(1) import Acquisition ... if DEBUG: wingdbstub.debugger.ResumeDebug() The problem now is, when started from inside WingIDE 1.1.9-1, I get the following exception when starting the script from inside the IDE: Attribute not found: 'module' object has no attribute 'debugger' Traceback (innermost last): File "<string>", line 1, in ? File "/home/freyp/EPcvs/HRS/Prod/HaufeCMSScripts/QueryTest.py", line 11, in ? wingdbstub.debugger.SuspendDebug() when stepping through wingdbstub.py (that I just copied from /usr/lib/wingide/wingdbstub.py over to the directory where my python script is, I am unable to step over the line 136: if not kWingDebugDisabled and not os.environ.has_key('WINGDB_DISABLED') and \ not os.environ.has_key('WINGDB_ACTIVE'): (looks like an exception that is not caught/handled by the Wing IDE debugger) and in the interactive debug probe, I also see no member debugger with the wingdbstub module: >>> dir (wingdbstub) ['WINGHOME', '__builtins__', '__doc__', '__file__', '__name__', 'imp', 'kAttachPort', 'kEmbedded', 'kExitOnFailure', 'kLogFile', 'kPWFileName', 'kPWFilePath', 'kSilent', 'kWingDebugDisabled', 'kWingHostPort', 'os', 'string', 'sys'] >>> (so probably it is kind of python magic?) Next try was to run the script from a bash shell: freyp@linux-frpkoend:~/EPcvs/HRS/Prod/HaufeCMSScripts> sh start_query.sh Traceback (most recent call last): File "QueryTest.py", line 11, in ? wingdbstub.debugger.SuspendDebug() File "2.2.0/src/debug/server/netserver.pyc", line 758, in SuspendDebug TypeError: tracer_stop_trace() takes exactly 0 arguments (1 given) the script used was was: freyp@linux-frpkoend:~/EPcvs/HRS/Prod/HaufeCMSScripts> more start_query.sh #!/bin/sh export PYTHONPATH=/home/freyp/Zope/Server/lib/python/ export INSTANCE_HOME=/windows/Work/Zope/HaufeCMSTest exec /usr/local/bin/python QueryTest.py /HaufeCMSTest/ImportTest /windows/Work/Zope/daten/import /windows/Work/Zope/test/export Does this mean I am no longer possible to use SuspendDebug/ResumeDebug from WingIDE 1.1.9? debug.passive-listen is set to true (as I need this for other Zope debugging sessions, too) but I could not find the .wingdebugpwd file. Probably I do not need it as I run both the ZEO Server and my script from within the same user account. Any help? Or, is there an other - better - way to speed up load time? regards Peter
