- Zope - Zope lists

Another problem
by a.wacknitz＠francotyp.com 14 Apr '00

14 Apr '00

Hi all, as formerly mentioned I try to return checked out files from a version management system with Zope. The check out is done within an external method (mthCheckout) that returns the binary data prepended by an appropriate header, eg. Content-Type: application/vnd.ms-excel Content-Disposition: inline; filename="mytable.xls" <binary data> BUT: When I call the external method within a document that only contains the following line: <dtml-call "mthCheckout(file)"> the user is prompted to choose what to do with the data. If open with Excel is chosen, Excel gets not only the binary data but also the header as its input. What shall I do to get the correct behaviour? What I want is that the appropriate application is called inside the browser filled with the binary data.

Ideas for the management-interface

Hi there, I got some ideas for the management-interface. First I wanted to get with= and height= attributes. Second I wanted to know the owner and the time of the last modify. Let me know what you think about it.

Re: [Zope] Zope Eating Memory for Breakfast

And we'd better figure out where it is. I have already seen several messages complaining about Zope's memory usage. ------------------------------------------------------------- OK, let us try to narrow down a bit. (1) Version: I also use Zope 2.1.4. System is Linux. (2) Webserver: ZServer with multiple threads. (3) Products: I use SybaseDAv2 for database adapter. I also use a bit of Gadfly (through SQLSession), this of course is a temporary feature because eventually I want to get rid of Gadfly. (4) ZODB: I don't have anything that dynamically changes Zope's ZODB, that is, I don't upload files into ZODB (Do you?), I don't create more Zope users on the fly. In fact, I believe my site can run from a CD-Rom, if necessary. (5) Size of ZODB: my Data.fs is about 9 MB. (6) Uptime pattern: the maximum time I have run Zope is less than a week. Usually I restart it a few times a week. (7) Memory growth pattern: my Zope starts out with 7 MB in each of the 4 threads. It starts to climb up slowly, by the end of the day it reaches 18 MB per thread. After 3 days it climbs up to 38 MB. That's about 160 MB total. (No, I don't think the threads are sharing memory, because the Linux "top" command also tells me the percentage of memory usage.) (8) Performance: I have severe problem with SQLSession and Gadfly, and also some problem with SybaseDAv2. I think the performance problem is related to the RAM memory consumption, because when I clean up Gadfly (deleting non-used table records), the Gadfly performance increased substantially. (9) Database Management cache parameters: (from Zope's control panel) Total number of objects in the database 4285 Total number of objects in all of the caches combined 1533 Target size 400 Target maximum time between accesses 60 Flush Cache: Full Sweep and Minimize don't help to reduce the memory consumption. ------------------------------------------------------------ Please post back your site's info. And let us see if we can narrow it down a bit. Anyone else that has memory problem please also help us to narrow down the problem. Why do we need to narrow it down? Because at this moment I am not sure whether the memory leak comes from a product or from Zope, and I am not sure whether it happens in Unix systems or in Windows as well, and I am not sure whether threads have problems, etc. Let's narrow down the problem first. thanks, Hung Jung ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

PTK and GUF
by Monty Taylor 14 Apr '00

14 Apr '00

Hello all, Maybe the problem is that I'm trying to use too many acronyms at once, but I'm having a problem using GUF, ZMySQLDA and PTK all together. Basically, I have a Portal up and going ok, and I have a Folder authenticated by a GUF against a MySQL database ok, but I want to have the Portal authenticate through the GUF. (I'm trying to get the portal up and running and integreted with an existing system, if you're wondering why) So I've got something like Zope |-GUFTest |-Portal But when I do http://zope/GUFTest/Portal it brings up the GUF authentication screen ok, but won't actually authenticate me. Is there something preventing Aquisition from handing the Roles found by the GUF to the Portal pages? I added roles in the GUF to match those in the Portal (Member, etc.), created a user in GUF with the same name as one in my MySQL database (to make sure the user folders were created properly) and then deleted the acl_users folder in the Portal. Does any of this sound like it makes sense? Any help anyone could offer would be of great use. Thanks! Monty

Database query -> HTML table
by Mike Orr 14 Apr '00

14 Apr '00

I'm trying to find a generic way to turn a database query into an HTML table the way the ZSQL Method's "test" routine does. I can do this with a literal list calling a Python method: Python method: table Parameter list: headers, data, table='<TABLE BORDER>', ntable='</TABLE>', tr='<TR>', ntr='</TR>', td='<TD ALIGN="left" VALIGN="top">', ntd='</TD>', th='<TH ALIGN="left" VALIGN="top">', nth='</TH>' Code: """ in : headers, list of strings, the column titles. : data, list of tuples, each row of data. : table, ntable, tr, ntr, td, ntd, th, nth, strings, how to render these HTML tags. """ headers_len = len(headers) data_len = len(data) if data_len == 0: return "" if data_len > headers_len: # Why doesn't Zope have a list() function? headers = headers[:] # Make a copy. ext = [ " " ] * (data_len - headers_len) headers.extend(ext) ret = [table, tr] for h in headers: ret.extend([th, h, nth]) ret.append(ntr) for row in data: ret.append(tr) for d in row: ret.extend([td, d, ntd]) ret.append(ntr) ret.append(ntable) return _.string.join(ret, '\n') I can then call it with a literal list: <dtml-var expr="table(['header1', 'header2'], [('value 1a', 'value 1b'), ('value2a', 'value2b')])"> What I want is a Python method that constructs the header and value lists and calls table(header, value). So that my documents can have a nice, clean: <dtml-var expr="sql_table( my_zsql_method(arg1, arg2, ...) )"> Where can I find some documentation on using a ZQSL Method object in Python? Or is there a way to access the table-creation code Zope uses in the "test" routine? -- -Mike Orr, mso(a)mso.oz.net -or- mso(a)oz.net (permanent: mso(a)jimpick.com) http://mso.oz.net/ English * Esperanto * Russkiy * Deutsch * Espan~ol

Can't start 2.1.6
by Tim Wilson 14 Apr '00

Hi everyone, I've installed Zope many times on my various Linux servers, but this one has got me puzzled. I'm working on a Mandrake 7.0 box here. I installed 2.1.6 and everything apparently compiled OK. I start it using # ./start -f '' -m '' Everything seems OK, but when I try to access my page I get this on the server console: 2000-04-14T01:56:46 ERROR(200) ZODB Couldn't load state for '\000\000\000\000\000\000\000\003' ------ 2000-04-14T01:56:46 ERROR(200) ZODB Couldn't load state for '\000\000\000\000\000\000\000\003' ------ 2000-04-14T01:56:46 ERROR(200) ZODB Couldn't load state for '\000\000\000\000\000\000\000\003' And this traceback pops up in my browser window.

manage from Opera on localhost
by Jerry McRae 14 Apr '00

14 Apr '00

Better details: In Win98, I can connect to localhost and do everything just fine using IE. Opera (3.6.2) will run the site at localhost correctly UNTIL I attempt to go into /manage. At this point Opera shows the tree correctly in the left frame. The right frame will display the original 'public' page, not the list of items. Most clicks on the tree structure produces the same result (always the index_html page output). Occasionally a partial management page shows up but it difficult to duplicate. This means I need (for the moment) to use IE to manage my local Zope site. Does anyone have suggestions for making Opera work all the time? ---d1 Jerry

Debugging Zope in Idle, setting breakpoints?
by Chui Tey 14 Apr '00

14 Apr '00

May be a little off-topic. So far, I have figured out how to load Zope from within Idle, (python 1.5.2's IDE) ZOPE_DIR = "C:\Program files\website" import sys, os start_path = os.path.join(ZOPE_DIR,'lib','python') sys.path.insert(0, start_path) os.chdir (start_path) import Zope, ZPublisher and invoking the debugger and executing ZPublisher to publish Zope objects [DEBUG ON] >>>ZPublisher.Zope('index_html') How do I set the same breakpoints like the ones done by ZPublisher when using the (d=1) option?

Is it in the CVS? ;-) No, not yet :( It looks like it may be a little trickier than I thought though, since we'll have to work around the default behavior of the publisher on a GET somehow.
