Andreas, I used what you recommended but now when I try to view the uploaded file it comes up blank. Is there a step that I am not doing? spaceAvail = context.Availability() data = file.read() fileSize = len(data) fileSize = (fileSize/1024)/1024 if spaceAvail < 80: if fileSize < 30: sizeTest = context.getDirectories('/var/www/html/da') if sizeTest > 900: message = 'Failure: No available disk space, see system administrator' return ('failure', new_context,{'portal_status_message':message}) else: test = new_context.manage_editPloneExternalFile(title = title,file = file,REQUEST = REQUEST) if not test: return ('success', new_context,{'portal_status_message':context.REQUEST.get('portal_status_ message', 'Content updated.')}) else: return ('failure', new_context,{'portal_status_message':test}) else: errormsg = 'Failure: File exceeds size limitation of 30MB' return ('failure', new_context,{'portal_status_message':fileSize}) else: errormsg2 = 'Failure: No disk space available in /var directory' return ('failure', new_context,{'portal_status_message':errormsg2}) Thank You, Laura -----Original Message----- From: Andreas Jung [mailto:lists@andreas-jung.com] Sent: Monday, November 08, 2004 11:16 AM To: Laura McCord; zope(a)zope.org Subject: Re: [Zope] Python question --On Montag, 8.

Zope X3 install
by John Poltorak 09 Nov '04

09 Nov '04

I ran 'make install' but don't see anything in /usr/local/Zope3 - my specified home. No error msgs were produced. Is there a log or can I generate some msgs to give me some indication of what has gone wrong? Am I correct in assuming that ZopeX3 should run on any platform supported by Python 2.3.4? -- John

Calling superclass methods from inside a Zope object

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all. We've a problem with a class like this: class MyObject(CatalogPathAware, SimpleItem): ~ def manage_afterAdd(self, item, container): ~ CatalogPathAware.manage_afterAdd(self, item, container) ~ ## other stuff here ## The problem is that MyObject apparentely does not have any visibility of the superclasses methods, if they came from some non Zope class (like the CatalogPathAware, and therefore the manage_afterAdd crashes. Any hint on this? The environment is Zope 2.6.4.

how to isolate a grave problem with zope
by Jonas Meurer 09 Nov '04

09 Nov '04

hello, we have some grave problems with zope 2.6.4: it crashes every time we put it under (some) heavy load, especially at one process, a convertion process. i tried to reproduce this bug in exactly the same installation on my home machine, but this finally doesn't work. on the machine where we encounter the problem, the problem appears in _all_ installed zope instances, which means: 5 instances from debian/testing packages of zope 2.6.4 with python2.2 1 instance from source installation of zope 2.6.4 with python2.2 1 instance from source installation of zope 2.6.4 with python2.1 to produce the bug, i have to install TinyTablePlus (as our Products depends on it), and some other own Products, but they are also installed on my local server, which doesn't crash. I stripped the Products Directory of zope down to native zope products and TinyTablePlus, used a fresh new installation of zope, and imported only 5 needed Products into Control_Panel/Products plus the one Application that does the convertion. on all 7 instances at our server zope get's crashed by the process, on my local machine, and even on windows zope servers it doesn't. i use everywhere exactly the same zope/tinytableplus versions, and my local system runs debian/unstable while the server runs debian/testing. python versions and installed modules of home and server are also synced. do you have any suggestions how to continue debugging, and how to isolate the problem? maybe there are some more components that could cause this crash, than just python (modules) and zope itself. bye jonas

ATAudio 0.3.5 released - for handling MP3 files in your Plone site
by Nate Aune 09 Nov '04

09 Nov '04

The Plone4Artists project team is pleased to announce version 0.3.5 of ATAudio. New features - **Streaming via Zope**. Thanks to Christian Scholz (MrTopf), ATAudio now makes use of the file iterator support in Zope 2.7.2. - **Limit file size**. Thanks to Christian Heimes (Tiran), you can now limit the size of the uploaded MP3 files. - **ATAudioFolder - Container for audio files**. There is now a container which displays a track listing and a CD cover image. Bug fixes - **Better WebDAV support**. Thanks to Sidnei da Silva (dreamcatcher), the uploads from OS X to WebDAV are more reliable now. Existing features - **MP3 files stored on file system**. The files are not saved in the ZODB, but on the file system. This prevents database bloat and exposes the files to 3rd party streaming software. - **ID3 tag extraction**. When you upload an MP3 file via WebDAV, the metadata is extracted and auto-populates the fields on the Plone form. Download To download the latest release of ATAudio, please visit the download page: http://plone4artists.org/downloads/ataudio/ Development All are welcome to join in the development of ATAudio. We would like to add support for other audio formats (OGG, Real, WMA), enable genre selection, allow for a sample/preview of the song, improve performance of the ID3 tag reading. CVS access in the collective: http://cvs.sourceforge.net/viewcvs.py/collective/ATAudio/ Documentation Please read the documentation in the 'docs' directory, and visit the online documentation page. http://plone4artists.org/development/teams/audio/. Brought to you by Plone4Artists ATAudio is a product developed by the Plone4Artists project team. Plone4Artists is a community driven project with the goal of assembling a Plone package catered to artist/musician communities. The Plone4ArtistsPackage product is a special Plone distribution which is pre-configured with many useful add-on modules. You can think of it as a complete portal solution for building artist/musician websites.

Stopping error messages in an external method
by Joe Goldthwaite 08 Nov '04

08 Nov '04

I've got a strange problem. It may not be Zope related but it only happens when my code is running under Zope. I'm using Win32com to create an OleDB connection to my database. (Don't ask why - it's a long story. Lets just say that MS SQL has problem working with remote tables when accessed through ODBC.) My routine executes a stored procedure step-by-step and displays the status of each step to the user. I'm returning the status with the RESPONSE.write method. This works great most of the time. I've noticed that if I put any print statements in my code that print to the standard device, it seems to confuse Zope. I've read that you want to either return a value from the external method or use RESPONSE.write but not both. I think the problem is that the OleDB execute method is printing an error message to the standard device. I'm using try:except: to trap any errors. When I run the code in the WingIDE, everything is fine. When I run it in Zope, it hangs when it hits the first error. I know the code hangs because I put some file write statements in the loop. When I run it under the debugger, I get a complete log. If I run it under Zope, the log ends when it hits the first error. Anyone know what I'm missing here? Thanks, Joe Goldthwaite

Doing adduser with the server stopped I was able to add a new user and then start the server and log in. My username had been replaced with "t"+username. I hope I do not have to go through the whole site and re-add all of the users ... Not even sure how I would go about that since I do not know people's passwords and there is no "rename" button for users... hmm... Anyhow, I am in now...

Adding a File Object to a LocalFS Object
by Asad Habib 08 Nov '04

08 Nov '04

Hello. I am trying to add a File object to a LocalFS object with id 'test'. I am able to detect the LocalFS object within the <dtml-in> and there is only one Local FS object in this particular parent Folder object. When the manage_addFile function call is executed, the File object is added to the parent Folder object instead of the contained Local FS object. Any help would be greatly appreciated. Thanks. - Asad <dtml-in expr="aq_parent.objectValues('Local File System')" prefix="current_localFS"> <dtml-if expr="current_localFS_item.getId() == 'test'"> <dtml-call "current_localFS_item.manage_addFile(id=REQUEST.form['fileName'],file=REQUEST.form['file'],title='',precondition='',content_type='application/pdf')"> </dtml-if> </dtml-in>
