Long PythonScript Problem
by Chris Withers 29 Apr '01

29 Apr '01

Hi Evan, Sorry to bug you but there appears to be a problem with Python Scripts longer than about 6kb. If you submit them via the web form, you either get 'connection reset by peer' or no data returned. You can reproduce this quite easy by using a _big_ block of hashes ;-) Any ideas? cheers, Chris

Zope shows internal setup (Bobo-Exception-File)
by Frank Tegtmeyer 29 Apr '01

29 Apr '01

Hi, is there any chance to suppress the Bobo-Exception-File header that is generated by a <dtml-raise Redirect>? Server: Zope/Zope 2.3.0 (source release, python 1.5.2, linux2) ZServer/1.1b1 Date: Sun, 29 Apr 2001 16:36:46 GMT Bobo-Exception-File: /web/zope5/lib/python/DocumentTemplate/DT_Raise.py Bobo-Exception-Type: Redirect Location: /kabine/ Bobo-Exception-Value: /kabine/ Content-Length: 0 Bobo-Exception-Line: 128 I don't think that there is any need to show my internal paths to the world. Is there any need for this header? Regards, Frank

Does mod_python conflict with Zope?
by Jason Cunliffe 29 Apr '01

29 Apr '01

I have been trying to install mod_python. I want to use it for the sections of the site which are served by Apache not Zope. Zope 2.3.2 Apache 1.3 Redhat 6.2 mod_python ./configure gives me a warning message about threading: ...checkingchecking... checking whether Python is compiled with thread support ..yes *****Warning***** Python is compiled with thread support. Apache 1.3 does not use threads. On some systems this will cause problems during compilation, on others it may result in upredictable behaviour of your Apache server. Yet on others it will work just fine. The recommended approach is to compile Python in a separate location and specify it with --with-python option to this ./configure script. Q1: Has anyone come across this? Q2: Do Zope and mod_python play well together? Q3: Should I wait and upgrade Redhat and Apache? If yes, what versions do you recommend with Zope 2.3.2++ ? - Jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']

[Fwd: installation question]

Installing Zope products is well documented, where I don't know ;-) Ask on the zope(a)zope.org list, I'm sure people there can explain it better than I... cheers, Chris Bobby Joe wrote: > > Actually, it's a silly question: How do I install it on Zope?

Hello, I would like to redirect a user to another page if their login fails, instead of showing the error: Zope Error Zope has encountered an error while publishing this resource. Unauthorized You are not authorized to access this resource. I guess that I need to catch an exception, but I am not sure where I need to catch it form. Please could anyone help? Cheers Neil

You either need to locate this server and shut it down or give Zope a different port. Dieter

But ZPublisher FileUpload instances have a "filename" attribute. Maybe, that is what you look for? Dieter

RE: [Zope-CMF] no mem for new parser

Hello Tres, Thanks fo your reply, you say my system is running out of memory, do you mean Hard Disk Space, RAM or what? I am with iServer, and they have allocated me 400Mb of HDD and I have only used about 150Mb -- I'll check though. I can also confirm that I have not done any changes to the code. I also had this error on my screen 2001-04-28T15:40:43 ERROR(200) ZServer uncaptured python exception, closin g channel <select-trigger (pipe) at 82e956c> (exceptions.MemoryError: [/usr/home /khine/usr/local/Zope/ZServer/medusa/asyncore.py|poll|83] [/usr/home/khine/usr/l ocal/Zope/ZServer/medusa/asyncore.py|handle_read_event|335] [/usr/home/khine/usr /local/Zope/ZServer/medusa/select_trigger.py|handle_read|77] [/usr/home/khine/us r/local/Zope/ZServer/medusa [/usr/home/khine/usr/local/Zop e/ZServer/medusa/asyncore.p and on the zope I get this Error Type: MemoryError Error Value: Out of memory while compressing data Traceback (innermost last): File /usr/home/khine/usr/local/Zope/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/home/khine/usr/local/Zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/home/khine/usr/local/Zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File /usr/home/khine/usr/local/Zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/home/khine/usr/local/Zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_contents) File /usr/home/khine/usr/local/Zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_contents) File /usr/home/khine/usr/local/Zope/lib/python/Shared/DC/Scripts/Bindings.py, line 324, in __call__ (Object: manage_contents) File /usr/home/khine/usr/local/Zope/lib/python/Shared/DC/Scripts/Bindings.py, line 354, in _bindAndExec (Object: manage_contents) File /usr/home/khine/usr/local/Zope/lib/python/App/special_dtml.py, line 236, in _exec (Object: manage_contents) File /usr/home/khine/usr/local/Zope/lib/python/DocumentTemplate/DT_In.py, line 721, in renderwob (Object: objectItems) File /usr/home/khine/usr/local/lib/python2.0/string.py, line 129, in join MemoryError: And then the server restarts. Can you confirm as to what you want me to do on the DirectoryView.py file -- where the following lines are, which I found on the file, if self.data is None or changed: try: self.data, self.objects = self.prepareContents(registry, register_subdirs=changed) except: # DEBUG import traceback traceback.print_exc() self.data = {} self.objects = () return self.data, self.objects you want me to change it to: try: self.data = data = self.prepareContents(registry, register_subdirs=changed) except: # DEBUG import traceback traceback.print_exc() raise Thanks Norman -----Original Message----- From: tres [mailto:tres]On Behalf Of Tres Seaver Sent: 28 April 2001 15:56 To: Norman Khine Cc: Zope-CMF Subject: Re: [Zope-CMF] no mem for new parser Norman Khine wrote: > > Hello I just gort this error and the server crashed. > > My set up > Zope version: Zope 2.3.2b2 (source release, python 1.5.2, linux2) > Python version: 2.0 (#2, Jan 8 2001, 16:54:34) [GCC 2.95.2 19991024 > (release)] > System Platform: freebsd4 > > no mem for new parser > Traceback (most recent call last): > File > "/usr/home/khine/usr/local/Zope/lib/python/Products/CMFCore/DirectoryView > .py", line 198, in getContents > > Any suggestions will be most appreciated Hmm, the relevant bits of getContents are (both for CMF 1.0 and the head of the CVS repository):: # CMFCore/DirectoryView.py, line #97 try: self.data = data = self.prepareContents(registry, register_subdirs=changed) except: # DEBUG import traceback traceback.print_exc() I can't see how that code could *possibly* yield the traceback you post -- did you trim it at all? At any rate, that code is broken; having caught the exception in order to print it, it doesn't re-raise it. For the nonce, please try adding raise just below the last line of the snippet. I find that error message deep in the bowels of the Python 2.0 C source:: # $PYTHON_2/Parser/parsetok.c, line #81 static node * parsetok(struct tok_state *tok, grammar *g, int start , perrdetail *err_ret) { parser_state *ps; node *n; int started = 0; if ((ps = PyParser_New(g, start)) == NULL) { fprintf(stderr, "no mem for new parser\n"); err_ret->error = E_NOMEM; return NULL; } So, it looks like your system is running out of memory, but the DirectoryView suppresses the error, and hence you get a core dump. Please submit a tracker issue for this problem: http://www.zope.org/Products/PTK/Tracker Do note your version of Python on the issue -- that was most helpful for tracking down the source of the exception.

Topic: I want to transfer work between two Zopes [2.2.5 -> 2.3.1] while both are running, using cut'n'paste, and also export/import .zexp files. Problem: How do I run both Zopes at the same time behind Appache Configuration: I am runing Zope2.3.1 on port:8888 = > Works fine I now want to run the old Zope 2.2.5 on port:88 Appache includes in its list of virtual servers: Handles the name-based server http://www.e-turb.com on address 64.7.41.100.
