kill Zserver zombie channels
by J�lio Dinis Silva 20 Feb '01

Hi, blatantly taken from ZServer/HTTPServer.py and adultered is this code to kill zhttp channels used in zope by way of an external method: def killzombies(): import ZServer from ZServer import HTTPServer from ZServer import medusa from ZServer.medusa import asyncore from ZServer.medusa import http_server for channel in asyncore.socket_map.values(): if channel.__class__ == HTTPServer.zhttp_channel: channel.close() return 1 I ignore here the zombie_timeout, Im just killing all channels. The problem is that I also kill the main python process. I would apreciate if any zserver/medusa guru can iluminate my mind on what I'm doing wrong here. In this code I only close zhttp_channels and not zhttp_server ones, so I dont understand why the server is also closed. Thanx for comments, Júlio Dinis Silva _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Zope probably has opened a communication (socket or pipe) with an external process (database?) and this process closed unexpectedly the connection (probably because it died). > 2001-02-19T20:21:08 ERROR(200) zdaemon zdaemon: Mon Feb 19 21:21:08 2001: Aiieee! > 938 exited with error code: 256 This is an "exit(1)". Some external component (database adapter?) has called exit with code 1. Unfortunately, I can not tell you which component does not work or even explain why. At your place, I would try to find log file of external components and see whether they contain some hints. Dieter

ZCatalog Lazy Results
by Johan Carlsson 20 Feb '01

20 Feb '01

Hi, I need to check an assumption I have made on the ZCatalog Brains and Lazy Results from reading the source. 1. The Brains gets its schema from the ZCatalog and this schema is basicly fixed. E.g. a search result always has the attributes defined by the Meta Data in the ZCatalog? I would rather be able to construct a Brain Schema at search time equivalent to the way theSELECT statement sets up the result attributes in SQL. Example: resultset = Catalog.searchResults(query,schema=('id','title','keywords')) 2. The laziness of the ZCatalog search result means it's batched?

Product release: ExtFile/ExtImage 1.1.0.beta1
by Gregor Heine 20 Feb '01

20 Feb '01

ExtFile/ExtImage Product 1.1.0.beta1 has just been released. Get it at http://www.zope.org/Members/MacGregor/ExtFile The new Version comes with many, many internal changes and some new features which will (hopefully) make ExtFile/ExtImage even more reliable: - You can set a 'level of undo' which determines in wich cases the external file is overwritten/deleted or renamed to '.undo'. - 'id collision bug' fixed, which caused unreferenced files in the repository, when an id of a new object already existed (thanks to Fred Yanowski). Instead of in the __init__ method, the file data is now passed to the object after it has been successfully added, via manage_file_upload. - 'wrong file size bug' fixed, which caused a wrong file size and resolution of the image and preview, after a new file was uploaded followed by an undo of this transaction. The filesize and resolution attributes have been replaced by corresponding methods which determine the respective value directtly from the file(e.g. width(), height(), prev_size(), ...) - Objects can be assigned an alternative id (instead of the filename) by the optional 'id' field in the manage_add method of ExtFile and ExtImage. - Uploaded preview images can be resized during upload (like the generated previews). - Images can be dynamically resized (thanks to Arno Gross): the index_html method now has two additional parameters ('width' and 'height') which cause the image to be resized on the fly. - Documentation updated. Because the product was rewritten in big parts this release is a beta version which might still have some bugs. I haven't had too much time for testing, so please report me any bug you find. I hope I will be ableto publish the next stable release within the next two or three weeks.

Photo Product Strangeness
by Michael R. Bernstein 20 Feb '01

20 Feb '01

I've been messing around with the Photo product, and I've noticed something odd about how it handles changes to the display sizes: When you create several Photo objects in the same folder (not in a ZPhotoAlbumPage), they affect each others display sizes. For example, changing one of the display sizes in one Photo will change the corresponding display in sibling Photo. Can anyone suggest how to fix this? Michael Bernstein.

Editing DTML Documents
by Philipp von Weitershausen 20 Feb '01

20 Feb '01

Hi there, Is there an efficient way to use an external editor to edit DTML Documents? Some people in my homepage group are tired of the ZMI and I can understand them, especially because of a lack of syntax highlighting. There is the possibility of copy'n'paste and upload again, but that's ugly. I also read that development on the Mozilla-based management tool is not continued. (That's sad, BTW...) Could I use WebDAV (don't have any experience with it) to retrieve and save the DTML source? If so, is there a good HTML source code editor (don't want WYSIWYG!) for Windows or Linux supporting WebDAV? Any suggestions welcome!

Python Scripts Bug & Question
by Chris Withers 20 Feb '01

20 Feb '01

Hi, Got a bug and an old unanswered question: The Bug: If I use an name other than 'context' to bind to context, I quite often (but not always :-S) get a KeyError on that name. The Question: If I'm calling a Python Script from a Python Product (for example), how would I pass a namespace to the script that would get bound as the namespace argument? cheers, Chris
