Zope 2.5.0, thread stack issues
by Geoff Gerrietts 09 May '02

09 May '02

I'm in the process of moving a site from a (much) earlier release of Zope, up to 2.5.whatever. In making this migration, I have encountered a problem with segmentation faults and spontaneous Zope restarts that sounds an awful lot like the problems some BSD users were encountering earlier. The principal difference between my case and theirs is that they're on BSD, where the thread stack size is by default yitty-bitty (64k), and I'm working on Linux, where the thread stack size is by default really huge (2MB). The solution previously recommended was to boost the thread stack size to 128k; Linux already provides well more. It's also a lot harder to boost the stack size under Linux; if there's a way to do it short of recompiling glibc, I don't know what it is, yet, and I've spent a lot more time than I should trying to find one. Now the symptoms I'm seeing pretty obviously have more to do with the signal handler for segfaults than any particular manifestation of segfault, but early triage attempts pointed at this thread stack problem. So, because I can't find hard diagnostic details in the mailing list archives, I'm hoping that someone might be able to tell me what the best indicator would be, or how to go about demonstrating that it isn't this problem.

Close Database Connection /Newbie Question
by Philipp Giere 09 May '02

09 May '02

Hello! Could someone please help me? In a little python-product I open a connection to Mysql like that: db = self.ZMySQL_Connection() With db.query("SQL") i send requests to the database. It works fine. But after a while I get an error "too many connections". Seems logical for me, because I don't close the connection. But how do I close it? Something like db.close() doesn't work. Thanks in advance Philipp

Zope 2.5.1 installation problems (zope dumping core)
by Malcolm E Davis 09 May '02

09 May '02

I have downloaded Zope 2.5.1 both as the source distribution and as the linux distribution. I have installed the source distribution onto an SGI running IRIX 6.5 (running python2 w_pcgi.py and then start) and installed the linux distribution onto a Linux box running RedHat 6.2 (running the install script and then start). In both cases, I can connect to http://hostname:8080/, login with the initial admin account, and get the initial index page with no difficulty. However, if I select the link to the Zope Management Interface, I get the three frames, but only the top one fills with anything. I get two "Document contains no data" dialogs. When I check the server it has dumped core and the shell window indicates that the server has restarted. No error messages are apparent in either the shell window or the var/Z2.log file. Since I have exactly the same problem in two completely different installs, but can find no similar complaints in the mail archives, I suspect I am doing some so completely newbie mistake that no one even mentions it. However, I am clearly stumped and would appreciate some help. As an additional data point, I actually tried the Zope 2.5.0 install on the SGI box as well. I had a similar problem, although then I did get the lower right frame and could perform some of the tasks. However, I wasn't able to get it to add the Zope Tutorial. Again the symptoms on the server side were core dumps with no apparent error messages in the logs. Finally, just for the record, I have tested this with Netscape 4.79 on the SGI, as well as Netscape 4.72 and 6.2 under Windows NT. Same problem with each. So it does not appear to be a browser problem. (Actually if some browser problem could crash the server, that would be rather scary anyway.) Thanks, Malcolm

aq_acquire problem
by Alexander Westholm 09 May '02

09 May '02

All, in a product method, I'm trying to access the REQUEST... the class that the method lives in inherits from Acquisition.Explicit so I tried to access it like so: self.aq_acquire('REQUEST') which yields an error about aq_acquire not being there... any ideas? -- Alex

parameters to dtml docs and methods?
by Dennis Allison 09 May '02

09 May '02

Suppose I have two DTML documents and/or methods, method A and method B. Method A Creferences Method B -- Method A: ... <dtml-var name="B"> ... which causes B to be published and it's "value" incorporated into A. Now, suppose there are some variables in A's namespace and further suppose that they are needed in method B. The question is how to pass them from A to B. What is the proper syntax? I find it surprising that I've been able to use Zope extensively without needing to know how to do this. But now I am beginning to write more modular and tigher code and need this mechanism.

Hi, how do I use the send-mail tag from a pythonscript, or better what is the replacement for the sendmail-tag in a ZPT Pythonscript combo ?

Zope 2.5 as an xmlrpc client
by Richard Wesley 09 May '02

09 May '02

I have been trying to write an external method to do XML-RPC calls from Zope 2.5 and I keep getting the rather uninformative error message "Fault" whenever I try to test a simple method. After poking around a bit, it appears that xmlrpclib is no longer included in Zope 2.5. Does anyone know why? Is there a version that works?

Question about <dtml-let ...>
by George M. Ellenburg 09 May '02

09 May '02

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Okay... I have a DTML Document called show_tip. In it, it calls a DTML Method called STYLE_TIP which contains essentially the stylesheet for the tool-tip. In STYLE_TIP, I'm picking a random integer, to show a random background image, but am using <dtml-let ...> to create a new variable (called TD_WIDTH) which I actually need to use from within the main show_tip DTML Document. ,---------- | Reason being is because the random backgrounds have different sized images | embedded in them, and flushed right, so I need to adjust the width of the | table depending on which image is ultimately picked so the text doesn't | overwrite the image. `---------- Part of the code is as follows: <dtml-if "imgID==1"> <dtml-let TD_WIDTH=400></dtml-let> background-image: url('/img/TIP-bg-1.png'); </dtml-if> ,---------- | If I put quotes around the TD_WIDTH=400 above, I get an invalid paramete | error when I try to save the DTML method. `---------- But, when I go to view show_tip, I get the following: Error Type: NameError Error Value: global name 'TD_WIDTH' is not defined The line that's calling it is: <table border=0 width=<dtml-var TD_WIDTH> align="left"> (I've also tried <dtml-var "TD_WIDTH">, too, but with no luck.) Can anyone steer me in the right direction? Could the problem be that the variable assignation is in a different DTML method from the DTML document that's calling it? Should the "400" (in TD_WIDTH=400) be quoted? I didn't quote it because I didn't want 400 to be misconstrued as a string, when I want it to be an integer. Thanks in advance. - -- George M.

cookie scope?
by Mark A. Robinson 09 May '02

09 May '02

Hang on this is kinda confusing: I set a cookie in a script in the top-level folder. Then move to a sub-folder and change the cookie value. Then I go back to the top-level folder and change the cookie. Lastly, I go back to the sub-folder and it has kept the value from the previous sub-folder's change not the last top-level folder change. So it's acting like I have created 2 cookies: 1 at the top-level, and 1 at the sub-folder level. Anyone ideas? Thanks!

Products and vhm
by Steven Pokrandt 09 May '02

09 May '02

I'd like to host other zope based sites. I see the need to allow admins of the vhosted sites access to creating there own produces Isn't the Idea of a product to be able to create custom objects? I do NOT what them to be able to delete or install system wide products. just ones that would be available within the vhm directory. is this possible, am I missing something...
