Turning back system clock
by Sinang, Danny 10 May '08

10 May '08

Dear All, The system clock of our Zope 2.7 machine accidentally got set to 2009. We noticed this mistake 6 hours later and we decided to set back the clock to 2008. How does this affect the integrity of Data.fs ? >From our observation : 1. Session write errors suddenly began to appear 2. Data.fs.index won't grow anymore and its timestamp remained at the time we set back the clock 3. Packing the database (which was 8 GB at the time) took too long without any signs of any Data.fs.pack file in the var folder. We decided to restart Zope after a few minutes. 4. There seem to be some catalog indexing problems as our catalog searches on a certain field doesn't work as reliably as it did before. We tried reindexing the field and even the catalog, but it timed out on us (lots of objects in the database). Has anyone here had any similar experiences ? How do I go about fixing this ? Using repozo.py last night, I made a full backup of Data.fs, copied it to a new instance, was able to create a new Data.fs.index, and eventually succeeded in packing the 8 GB database to just 2.4 GB. But it took quite a while - like 10 or 15 minutes before any Data.fs.pack appeared. I haven't checked yet if the catalog indexing problem has gone away. Regards, Danny

Making Zope stop storing old object versions
by Sinang, Danny 09 May '08

09 May '08

Hello, We've got lots of Catalog reads and writes and our Data.fs is growing at an immense rate. Is there a way we can tell Zope to stop storing old object versions to limit the growth and not have to pack that often ? Regards, Danny

Question about adapters
by Martijn Jacobs 09 May '08

09 May '08

Hello guys. A question about adapters : I've written two adapters wich implement my own interface IMyAdapter. The first adapter adapts CMFCore.interfaces._content.IFolderish objects and the other one CMFCore.interfaces._content.IContentish objects. One of the base classes of the IFolderish objects also implement the IContentish interface, so when I adapt folderish objects with IMyAdapter(object), the adapter registered for the IContentish objects always "wins". (and if it's a folderish object I want the adapter for IFolderish to jump in). In other words : How can I influence the order of adapter lookup? I'm feeling there should be a simple solution for this (applying a marker interface to folderish objects?), so I hope someone can point me in the right direction. Kind regards, Martijn. -- Martijn Jacobs Four Digits, Internet Solutions a: Willemsplein 15-1 6811 KB Arnhem NL kvk: 091621370000 | btw: 8161.22.234.B01 e-mail: martijn(a)fourdigits.nl | web: http://www.fourdigits.nl tel: +31 (0)26 44 22 700 | fax: +31 (0)84 22 06 117

problem attach file / Zfile - more informations
by Frederique Blondelle 02 May '08

02 May '08

Hello, I have created a zclass with zfile as basic class. With this class, users could, via a web form, send an attached file if they want. With zope 2.5 (my previous version) if users don't attach a file, there is no problem with zope 2.10, if there is no file attached, I have an error message : 'file not specified". It seems that attach file is mandatory. Here, the complete message from the events log : Traceback (innermost last): Module ZPublisher.Publish, line 119, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 42, in call_object Module OFS.DTMLMethod, line 144, in __call__ - <DTMLMethod at /assistance/do_add> - URL: http://assistance.abes.fr/do_add/manage_main - Physical Path: /assistance/do_add Module DocumentTemplate.DT_String, line 476, in __call__ Module DocumentTemplate.DT_With, line 76, in render Module DocumentTemplate.DT_Util, line 196, in eval - __traceback_info__: _ Module <string>, line 1, in <expression> Module OFS.DTMLMethod, line 137, in __call__ - <DTMLMethod at /assistance/Quest_susvp_add> - URL: http://assistance.abes.fr/Quest_susvp_add/manage_main - Physical Path: /assistance/Quest_susvp_add Module DocumentTemplate.DT_String, line 476, in __call__ Module DocumentTemplate.DT_With, line 61, in render Module DocumentTemplate.DT_Util, line 196, in eval - __traceback_info__: REQUEST Module <string>, line 1, in <expression> Module ZClasses.ZClass, line 454, in createInObjectManager Module ZClasses.ZClass, line 485, in fromRequest Module ZPublisher.mapply, line 89, in mapply Module OFS.Image, line 120, in __init__ Module OFS.Image, line 501, in _read_data ValueError: File not specified Who could help me THanks
