newbie: How to responde to failed logins?
by Neil Blue 29 Apr '01

29 Apr '01

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

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.

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.

running multiple Zopes behind Appache

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.

start stop problems after renaming Zope installation
by Jason Cunliffe 28 Apr '01

28 Apr '01

hum: Newbie Trouble understanding how Zope 'sees' itelf and where it sets this ... Am upgrading from Zope 2.2.5 to 2.3.1b3 on Linux Redhat6.2 Running behind Apache 1.3 with Proxy Pass Directives and Siteroot. Thought I would install install Zope in a separate folder and do some private tests and imports firsts. I installed Zope-2.3.1-src.tgz but after installing renamed its root folder to 'Zope231' [I'm a bad dislexic typist]. Problem: It starts OK but when I try to stop from su I get this error: [root@colocate05 Zope231]# ./stop cat: /web/Zope-2.3.1-src/var/Z2.pid: No such file or directory Obviously when running Zope still 'thinks' it is in /web/Zope-2.3.1-src/ but it is actually /web/Zope231/ now. Q1: Where and when does Zope set this ? Q2: How do I change it? Q2: How best to install Zope adn upgrades into a newly named directory without these problems? Using Zope manage control panel to restart or stop I get the same problem: Traceback (innermost last): File /web/Zope-2.3.1-src/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /web/Zope-2.3.1-src/lib/python/ZPublisher/Publish.py, line 187, in publish File /web/Zope-2.3.1-src/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /web/Zope-2.3.1-src/lib/python/ZPublisher/Publish.py, line 171, in publish File /web/Zope-2.3.1-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_restart) File /web/Zope-2.3.1-src/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_restart) File /web/Zope-2.3.1-src/lib/python/App/ApplicationManager.py, line 385, in manage_restart (Object: Traversable) File /web/Zope-2.3.1-src/lib/python/zLOG.py, line 213, in LOG File /web/Zope-2.3.1-src/lib/python/ZLogger/ZLogger.py, line 17, in log_write File /web/Zope-2.3.1-src/lib/python/ZLogger/stupidFileLogger.py, line 99, in __call__ File /web/Zope-2.3.1-src/lib/python/ZLogger/stupidFileLogger.py, line 151, in stupid_log_write IOError: (see above) Thanks - Jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']
