BTW, we have related those unnecessary commits to CMFQuestions, an old plone product now superseded by PloneSurveys... We came to that not by inspecting the code, but by realizing there were too many conflicts related with CMFQuestionnaire. We removed it, and the commits vanished.

For this what I was thinking was to introduce a new control >apart from the regular ones. Apparently, my previous message has not been clear enough. Let's try again: The effect of changing the effective user (e.g. to "root") is not restricted to a single thread but affects all threads in the current process. If you do this in one of your ExternalMethod's, all Zope requests start to be executed with root as effective user -- even those not executing your ExternalMethod. If at the end of your ExternalMethod, you switch back to the former user, the complete Zope process switches back -- even (other) requests that are currently executing an ExternalMethod that should run as root -- and which is likely to fail therefore. I hope the description should show you that this is the wrong approach. Please read my previous message (and other messages in this thread) to learn about alternatives. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Really funny
Unfortunately, this means that is will be quite difficult
to find the cause of your problem.
One approach would be to emulate in a pure Python interpreter
what "zopectl debug" would do for us.
You may try:
bin/zopectl shell # will create a new shell process with the correct
environment
from Zope2.Startup.run import configure
configure('etc/zope.conf')
# this is likely to raise the exception you have earlier reported
from pdb import pm
pm() # analyse the exception context

[Zope] Help writing test where bobobase_modification_time changes
I'll try to explain as briefly as possible.
I've got a working cache pattern that keeps a cached version of a Zope
file's content and only when it changes (by >
bobobase_modification_time) the cache is invalidated and recreated.
Here's the gist of my test
class Test(ZopeTestCase.FunctionalTestCase):
def test_recreateCache(self):
""" bla """
self.folder.manage_addFile('foo.js','FOO data')
url = self.folder.mytool.cacheFile('foo.js') # pseudo code this time
path = urlparse(url)[2]
response = self.publish(path)
self.assert... tests on response...
_file = getattr(self.folder, 'foo.js')
_file.manage_edit(_file.title, _file.content_type,
filedata='new data')
newurl = self.folder.mytool.cacheFile('foo.js')
assert newurl != url, "url hasn't changed :("
The reason it fails on the last line is that the time difference
between the first time and the second time is nil. Adding a
time.sleep(1) won't change anything because the
bobobase_modification_time() doesn't change.
How can I solve this? Make one big transaction two without having to
use transaction.get().commit() which I don't think I can use in unit
tests as per Dieter's advice.
Grateful for help.
Peter

Re: [Zope] ExternalMethod - add new parameter
Hi Rishi. Can you telll me where should I look in the source(Code segment where external methods are loaded and executed) External methods are not just 'called' or 'loaded', they are executed in a zope thread which belong to the zope user. Changing the effective user would be a complex and risky task to do and is probably not needed your your project. Can you explain what you're trying to do in those External methods? Maybe we can help you to find a more elegant, simple solution.

Re: [Zope] ExternalMethod - add new parameter
Zope itself should not be running as root. The external method will run as whatever user zope is running as. If you insist on doing this kind of thing, which is a pretty bad idea, then use os.system(...) or one of the popen(...) commands to call another program that you have permitted root access by a somewhat controlled process, such as sudo. At least then, you will have a log of changes (unless you make a security mistake and the log can itself be altered). jim penny Chris Withers <[EMAIL PROTECTED]> Sent by: [EMAIL PROTECTED] 04/08/2008 09:52 AM To rishi pathak <[EMAIL PROTECTED]> cc Dieter Maurer <[EMAIL PROTECTED]>, zope@zope.org Subject Re: [Zope] ExternalMethod - add new parameter rishi pathak wrote: > I dont have a need to run all the external method as root, only > some of them.

Re: [Zope] ExternalMethod - add new parameter
Hi Dieter, I dont have a need to run all the external method as root, only some of them. For this what I was thinking was to introduce a new control apart from the regular ones. viz id , title , Module Name and Function Name by name of 'Run as root', it would probably be a checkbox.Then at the point when external method code is executed I would check for the said control and if checked would get it executed as root.
