zope core dump
by seb bacon 10 Jul '01

10 Jul '01

I just tried to restart zope and got a core dump. The backtrace (pasted below) indicated a problem with the binascii module, and sure enough, trying to import it reproduced the segfault. I reinstalled python and it all worked again. This isn't strictly a Zope issue but I wondered if anyone's seen this before, or can explain what might have happened? I'm a bit out of my depth when it comes to this kind of thing... cheers, seb ---- (top of backtrace follows) #0 0x40181ba3 in frame_dummy () from /home/Zope-2.3.2-src/lib/python2.0/lib-dynload/binascii.so #1 0x40181a01 in _init () from /home/Zope-2.3.2-src/lib/python2.0/lib-dynload/binascii.so #2 0x40130c0a in dl_open_worker (a=0xbfffaa48) at dl-open.c:199 #3 0x4000ac3b in _dl_catch_error () at dl-error.c:99 #4 0x40130d1d in _dl_open () at dl-open.c:210 #5 0x4002e3d3 in dlopen_doit (a=0xbfffab58) at dlopen.c:41 #6 0x4000ac3b in _dl_catch_error () at dl-error.c:99 #7 0x4002e8b9 in _dlerror_run (operate=0x4002e3a8 <dlopen_doit>, args=0xbfffab58) at dlerror.c:125 #8 0x4002e393 in __dlopen_check ( file=0xbfffaea4 "/home/Zope-2.3.2-src/lib/python2.0/lib-dynload/binascii.so", mode=2) at dlopen.c:53 #9 0x8069e14 in _PyImport_GetDynLoadFunc (fqname=0xbfffb334 "binascii", shortname=0xbfffb334 "binascii", pathname=0xbfffaea4 "/home/Zope-2.3.2-src/lib/python2.0/lib-dynload/binascii.so", fp=0x8266ff8) at dynload_shlib.c:81 #10 0x80640c7 in _PyImport_LoadDynamicModule (name=0xbfffb334 "binascii", pathname=0xbfffaea4 "/home/Zope-2.3.2-src/lib/python2.0/lib-dynload/binascii.so", fp=0x8266ff8) at ./importdl.c:42 #11 0x806279e in load_module (name=0xbfffb334 "binascii", fp=0x8266ff8, buf=0xbfffaea4 "/home/Zope-2.3.2-src/lib/python2.0/lib-dynload/binascii.so", type=3) at import.c:1236 #12 0x8063355 in import_submodule (mod=0x80b7bcc, subname=0xbfffb334 "binascii", fullname=0xbfffb334 "binascii") at import.c:1755 #13 0x8062f53 in load_next (mod=0x80b7bcc, altmod=0x80b7bcc,

How long below the radar?
by alan runyan 10 Jul '01

10 Jul '01

I couldnt resist jumping in. I have been playing w/ ZOPE and BEA Weblogic for over two years. I would say I know more about Weblogic than ZOPE, but I am more productive w/ ZOPE. thus my 'love' for ZOPE. I believe that before ZOPE can truely take off it will need a miniVend like solution to get the PHP/CF/ASPers to ZOPE. Why? Because everyone needs this functionality - Now. In fact, I want it, but not enough to put the time into either of the two existing solutions. When you come to Zope, its almost impossible to build something like this the first day, even if you are somewhat fluent with Python. Why? Tools/Experience from other systems are not out-of-the-box. Sessions _are_ fundamental in keeping state in a shopping cart application. You can not easily embed logic w/ presentation (please dont flame me.) -- all other systems do it. ZOPE is the only one that *forces* you to be correct. people dont want correct, they want it to work, Now. After using resin, http://www.caucho.com/ for over a year, the dynamically loaded classes, form based authentication (i hear this at least 4-5 times a week on #zope), jsp, easy configuration xml file (?environment variable explosion?), sessions, and clear API documentation. I'm not saying make ZOPE - servlet/jsp like I'm just pointing out what I find **incredibly** useful for large scale ecommerce projects, http://www.skyauction.com/ Redhat's solution is a evolved minivend - http://interchange.redhat.com/cgi-bin/ic/index.html I was on #zope for the talk about creating pay modules for ZOPE. I am a fan of this idea. I think having a 100% Zope Certified Product could lead to more consistent configurations/out-of-the-box products -- how many products besides the DC released ones would you give a 100% Zope Certified Product label to? I havent seen that many at all. With some work they could get it, but very few out-of-the-box. The last thing people want is to have to download 3 different products to get another product working. It would be different if these dependancies were on products like PageTemplates in that they are 100% Zope Certified. Seeing that there are over 300 products, its about time the 'truely drop-in products' are seperated from the almost drop-in workable products. I would like to see a Roadmap for ZOPE. A option to purchase 100% Zope Certified Products (I dont believe this was in the survey sent out to the community) that Work Now. I would like to have a clearer way of development path, a Best Practices. ZEO is a huge secret, if you can get the average ASP/PHPer to be able to use ZEO and get interactive debugging working in the a few hours (or out of the box!! ;) -- you will see a new tune sung about 'ease of use'. I think with the right tools coming out of the box w/ ZOPE in the future it will be gain even more popularity. Preserving quality with a 100% Zope Certified label will give people confidance in the testing/reliability of their Products. And with the option of purchasing modules maybe some people can make some(quite a few?) bucks on the side ;). cheers, ~runyaga

Python Script bug?
by Chris Withers 10 Jul '01

10 Jul '01

Hi, The following code: objects = map(lambda b: b.getObject,brains) Results in: Error type: Unauthorized Error value: __len__ File E:\Zope\current\Products\CMFCore\FSPythonScript.py, line 187, in _exec (Object: index_html_postings) (Info: ({'script': <FSPythonScript instance at 01BB2C20>, 'context': <SwishdotSite instance at 01C09950>, 'container': <SwishdotSite instance at 01C09950>, 'traverse_subpath': []}, (), {}, None)) File Script (Python), line 5, in index_html_postings File E:\Zope\2379B4~1.2\lib\python\Products\PythonScripts\Guarded.py, line 204, in __careful_map__ (Object: <lambda>) File E:\Zope\2379B4~1.2\lib\python\Products\PythonScripts\Guarded.py, line 273, in __getattr__ File E:\Zope\2379B4~1.2\lib\python\Products\PythonScripts\Guarded.py, line 152, in __careful_getattr__ ...and yet the following code: objects = [] for brain in brains: objects.append(brain.getObject()) ...works fine. This is on Zope 2.3.2, is it a bug? cheers, Chris

LDAPLoginAdapter
by Nicolas Vincent 09 Jul '01

09 Jul '01

I use Zope 2.3.2, python 1.5.2 and python_LDAP 1.1 . I want to use loginadapter 1.5 to authenticate the users who try to connect to the portal I build and during all his session I need to know a lot of things about this user. The loginadapter connects itself to the localhost:390 wich is linked by a secure stunnel to the port 389 of another machine which is a OpenLDAP 2.* server. I use the Loginscreen & cookie option of the configure tab and the RDN of the LDAP database is uid. The authentication is made by uid and work perfectly. My first problem is that : Where I can get the LDAP attributs (such mail or another descriptive field of the LDAP database) after the authentication? AUTHENTICATED_USER contains only the uid (AUTHENTICATED_USER.mail for example is not define, even if I specify it in the loginadapter schema). My second problem is that when I do a research with the search tab of the Loginadapter, it doesn't find anything, as if the database would be empty. On the contrary, the research with the search tab of the LDAPUserManager work perfectly. Thanks for your futur response Le Lapinlove _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Management Interface in ZODB
by Tim R Ansell 09 Jul '01

09 Jul '01

I have a couple of small patches here that allow you to override the manage options (i.e. manage_tabs, manage_page_header, manage_page_footer) in the ZODB. This simple patch seems a nice way to provide this option without breaking compatibility with the current system. It patches the App/Management.py and OFS/Application.py file. This also causes risk of locking yourself out of management, there are 2 ways around this problem; First is to ftp/webDAV in and delete the offending file. I've also added a SUPPRESS_CUST_MANAGE option, (for example abc/SUPPRESS_CUST_MANAGE/manage_main) when this is in the path it will stop use the core zope management interface instead of the custom ones. The problem with this is that i get a "<Override instance at 8189638>" instead of the DTML code that should be in place of the object. As well this option IS NOT thread safe. I'm looking for a better solution but i can't think of one? What do people think of this patch? Is there a better way to do this? Is it possible to get a patch similar to this integrated into the Zope core because it's an extremely useful. Hope to hear from you soon Mithro ############################################################################## # # Zope Public License (ZPL) Version 1.0 # ------------------------------------- # # Copyright (c) Digital Creations.

Pack tops ZEO Client :-(
by Chris Withers 09 Jul '01

09 Jul '01

Hi, I just tried to pack a 2.4.0b2 Zope server via a ZEO client connected to it. The browser icon just sat there and spun. When I did a top on the server, none of the threads for the ZEO client or the ZSS were anywhere to be seen ;-( Any ideas what happened? cheers, Chris

Content integration question
by Webkitschen Mailbox 09 Jul '01

09 Jul '01

newbie question I'm have a lot of structured content that I want to batch process into a Zope installation some of it i already have in zclass instances that i want to change to new zclass instances and other stuff is in a variety of access database and Excel spreadsheets, CSV files etc. I have thought about using an external database but i don't think it warrants it for this situation. I also develop Mediasurface applications. there is an integration module that allows you to import CSV or XML marked up content into specified 'Item type', creating a new instance of the type for each record. Item types are a similar concept to Zclasses. what i'm getting at is that i need a similar means in Zope to perform this kind of integration process any guidance would be greatly appreciated

manage_workspace => index_html
by The Doctor What 08 Jul '01

08 Jul '01

My workspace keeps being redirected to index_html.... Example: http://host/manage_workspace redirects me to http://host/ Likewise, http://host/pi/manage_workspace redirects me to http://host/pi/ I don't understand it, but I see that netscape navigator doesn't seem to have this problem. But Mozilla and Lynx does! Here is some output from lynx: lynx -head -source -nopause -auth=id:pass http://linuxasm.gerf.org:9673/manage_workspace HTTP/1.0 302 Moved Temporarily Server: Zope/Zope 2.3.2 (source release, python 1.5.2, linux2) ZServer/1.1b1 Date: Mon, 14 May 2001 20:28:12 GMT Bobo-Exception-File: /usr/lib/zope/lib/python/App/Management.py Bobo-Exception-Type: Redirect Location: http://linuxasm.gerf.org:9673/index_html Bobo-Exception-Value: http://linuxasm.gerf.org:9673/index_html Content-Length: 0 Bobo-Exception-Line: 152 X-Cache: MISS from lego.gerf.net X-Cache-Lookup: MISS from lego.gerf.net:3128 Proxy-Connection: close What's going on? Is this a Mozilla problem? If so, why is lynx doing the same? How should I go about trouble shooting it?

DateTime class not recognizing timezone correctly...
by Steve Spicklemire 08 Jul '01

08 Jul '01

Hi -dev folk.. I ha(d) a problem where DateTime was basing the local timezone on time.tzname, and getting it wrong. (tzname comes from the abbreviation, which in Indiana is 'EST', but DateTime really wants 'US/East-Indiana'. So.. I patched DateTime as follows.. I saw a proposal in the archives about this kind of solution. Any other ideas? How are other folks handling this? thanks, -steve diff DateTime.py myDateTime.py 96,97c96,107 < try: from time import tzname < except: tzname=('UNKNOWN','UNKNOWN') --- > > tzname = None > try: > from localzoneinfo import tzname > except: > pass > > try: > if tzname is None: > from time import tzname > except: > tzname=('UNKNOWN','UNKNOWN')
