Zope 2.6 traceback problems
by Jesse D'Aguanno 20 Dec '03

20 Dec '03

Hello, I recently moved a number of production servers from Zope 2.5.1 to 2.6.2, I'm trying to figure out why the tracebacks are so different in the 2.6 tree. I do know that error messages and tracebacks are now available in the /error_log object (That took me a bit of mailing list archive digging :), but I'm referring to the actual content of the tracebacks. In 2.5.1 my tracebacks would tell me the actual zope object and most of the time the line number where zope was encountering a problem. For example, if I have a dtml-document which runs a number of SQLMethods and a number of PythonScripts and one of those SQLMethods had an error, 2.5.1 would tell me the id of the exact zope object (eg. SQLqueryblah) and line number where I had a problem, but zope 2.6.2's tracebacks will only tell me that it encountered an error somewhere in the zope plumbing, like the database adapter. Then I get to go through each and every SQLMethod that is called on that page and determine which one has the error. As you might imagine, this makes debugging a problem a much longer process and a very frusterating one. If someone is familliar with this problem and can suggest a fix for it, that would be very much appreciated. Even if someone just knows the reason for this change, I would be much obliged. Thank you very much for your time, -- Jesse D'Aguanno JJRaM, Inc. 10217 Fair Oaks Blvd., Suite B Fair Oaks, CA 95628 http://www.jjram.com

Accessing a file on a network drive
by Jørgen Larsen 20 Dec '03

20 Dec '03

Hi, I'm trying to open a file from a windows network drive from a external python script in ZOPE: The operation looks like this: fh = Open('\\\\projects/subprojectname/sound/C01-1_FAS_01AS.wav','rb') I also tried: fh = Open('\\\\projects\\subprojectname\\sound\\C01-1_FAS_01AS.wav','rb') Both operation fails with this error: Error Type: IOError Error Value: [Errno 22] Invalid argument When I try the two operation above from a standalone python script everything works fine. I also tried to open a locale file from my ZOPE script example: fh = open('c:\\test.txt','rb') And this works fine too. What am I doing wrong? Best Regards Jørgen Larsen

Defining classes in scripts in Zope 2.7, examples are broken
by Jeff Kowalczyk 20 Dec '03

20 Dec '03

What is the new convention for creating classes in scripts? Is it disallowed now? The examples (File Library, Guest Book) define exception classes in their add/upload scripts, which results in an error on Zope2.7b3 Win32. Thanks. Error Type: NameError Error Value: global name '__name__' is not defined """Create a guest book entry. """ class LimitExceeded(Exception): """raised when too many entries are submitted""" entries_folder=container.Entries # create up-to 5 unique entry ids, a real app might not impose such a # small limit, but we do because this is just an example after all n=len(entries_folder.objectIds()) if n > 4: raise LimitExceeded, "limit on number of entries (5) exceeded" id='entry_%d' % n

Remove (version) locked resource
by Rod Thorburn 19 Dec '03

19 Dec '03

I am new to Zope; working through the Zope Book. I created a version object to test out this functioality, made changes to some objects etc. However, perhaps I didn't have 'cookies' configured properly, but some versioned changes were published on the save command and others were not. I tried to backout of what I had done using the 'Undo' feature, but it seems that I have created a right old mess now! The problem is that there is a version lock on a folder that I can't get rid of. If I start the version and then try to view the contents of the folder concerned I get this error message : Changed in a Version Site Error An error was encountered while publishing this resource. Error Type: POSKeyError Error Value: 000000000000332b Is there any way of forcing a delete version / remove lock so that I can at least try again, as opposed to uninstalling / reinstalling the whole Zope server and database?

Multiple user folders
by Heimo Laukkanen 19 Dec '03

19 Dec '03

Hi all, this is a question that arose in one client situation where part of the users were defined in LDAP and others were just defined in normal user folder. Client had created a drirectory structure where on the subfolder he had the LDAP userfolder and normal userfoder on top folder, this way authentication worked for both groups. However I started to think whether anyone had done yet a userfolder that could have multiple sources for users in one userfolder? -- -huima

Lotus Domino frontend

Did anyone successfully install Zope with Lotus Domino operating as a front-end? We have Lotus Domino used as a virtual hosting solution. All virtual websites use Domino directly. Now we are going to attempt adding a virtual web supported by Zope. -- Milos Prudek

accessing dtml-in SQL variables
by Lalo Castro 19 Dec '03

19 Dec '03

Hi, What is the syntax (if it exists) for accessing SQL fields from a <dtml-in>? For example, say you had a SQL method that performed a 'select * from data_base'. If you called that SQL method by <dtml-in "SQL_method(variables)"> that would return the entries in the database. Then you could directly show those entries using the names of the database fields as variables. But, how could you call those entries (variables) without explicitly using the names of the database fields? I'm looking for something like the sequence-item tag, where the name of the variable itself isn't needed. Those entry/variables are pushed onto the name space, but I'm not sure how to access the name space to get those variables. Our location is using Zope 2.6 and Python 2.1.3 The context to this is we are building a generic SQL adaptor from scratch using Zope. The modify function (calling an UPDATE SQL method) contains 2 Forms, one to search for applicable entries and the second to narrow down the search of entries to modify. Both use a SQL method that searches the database. The method is called from <dtml-in "SQL_method(variables)". When it returns those entries we have to hand-code all those names/values to be changed into the function itself, for each table, and each database. This would be much easier if there was a way to call the database fields returned from a <dtml-in select_all_method> without explicitly naming the fields. If anyone knows how to call those variables in a generic way, or has a better way for doing this than we've described, please let us know. Thanks in advance. -- Lalo Castro Programmer/Analyst McHenry Library (831) 459-5208

Uploading audio mp3
by Børge Kjeldstad 19 Dec '03

19 Dec '03

Hello : ) I have tried to upload some mp3 music files to my zope 2.6.1. To do this I have both tried the "add file" option in the management interface and used the product "CMF-friendly Audio object" found here: http://zope.org/Members/bowerymarc/CMFAudio However when i play (view) these mp3 songs or embed them in a web page, some of the songs get a silent moment (about a second) just a few seconds after I start to play them. Now I wonder what could be the reason for this? I have tried to modify/compress an mp3 song using lame, but this does not help. I have also used winamp to study the diferences between the mp3 files that play well and those who does not. A difference I notice is that the well played songs are encoded by "Exact Audio Copy (Secure mode)", whereas the unsuccessful songs have no information about encoding. I do not know if this matters. Thanks! Børge

VHM Question
by Marc Stein 18 Dec '03

18 Dec '03

I have a Plone site (I know...this is the Zope list, but I don't think that this is a Plone question) named 'intranet'. I want to use VHM to resolve intranet.yyy.com to this folder. Zope is currently listening on port 80 and Apache is not being used. I have creates a VHM mapping which reads intranet.yyy.com/intranet This causes intranet.yyy.com to resolve to the root of my Zope installation instead of to the intranet folder. If I enter intranet.yyy.com/intranet I get to the right folder. Clearly, I'm doing something wrong...can someone please tell me what it is. Many thanks in advance. Marc Stein
