ZConfig keys
by Godefroid Chapelle 04 Aug '04

04 Aug '04

Hello, I would like to confirm that ZConfig keys are case insensitive and that the corresponding attributes on the config object returned by the 'loadConfig' call are always lower case. The only thing that seems relevant about keys and case sensitivity in the documentation does not state it explicitely : '''When this schema is loaded, a set of defaults for the derived section type is computed. Since basic-key is case-insensitive (everything is converted to lower case), ‘foo’ and ‘Foo’ are both converted to ‘foo’, which clashes since key only allows one value for each key.'''

More POSKeyErrors than I know what to do with
by Richard Jones 04 Aug '04

04 Aug '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Our 2.7.1-based production server has started throwing up a lot of POSKeyErrors recently. Forcing regeneration of the Data.fs.index didn't fix it. Packing didn't fix it or generate any new errors - we haven't packed the database since it went live. fsrecover.py doesn't do anything. Running fsrefs.py on the Data.fs gives *scary* long output (attached both unpacked and packed ouput). I haven't been able to get checkbtrees.py to produce any useful output (it doesn't appear to want to poke into the Application). I'm not sure it'll tell me any more than fsrefs.py though. - From my reading of the fsrefs.py output, it looks like the corruption is the result of a single transaction. I'm more than happy to look into this further, and also to supply the Data.fs (200Mb unpacked, 20Mb packed) to help analyse it.

Forgot to Cc: zope-dev -----Mensagem encaminhada----- From: Leonardo Rochael Almeida <leo(a)hiper.com.br> To: Santi Camps <scamps(a)earcon.com> Subject: Re: [Zope-dev] Referencial Integrity in ZCatalogs Date: Mon, 02 Aug 2004 17:05:53 -0300 I would suggest you take a look at mxmRelations, however Zope.org workflow is keeping it out of reach, and I couldn't find it on MaxM's own site. The URL for it would be: http://www.zope.org/Members/maxm/products/mxmRelations but right now it requires a login. If any kind soul from the Zope web team could release it, or if MaxM could post it somewhere else, that would be very nice. Cheers, Leo

Referencial Integrity in ZCatalogs
by Santi Camps 02 Aug '04

02 Aug '04

Hi all, I've been developing database oriented applications for about 10 years, using zope with Relation DDBB for one year and a half, and just one year using Zope with ZODB in my applications. At this point, I can see a lot of advantatges of use ZODB with Zope, but there are some points where the relational model was more useful to me. In fact, the main problem in my applications are relationships. In a relational world, you can specify relations using foreign keys, and also say what action should be done on delete or on update (no action, set null, restrict, cascade, set default). This is very useful developing business oriented applications. Using ZODB some of these relations can be done using containment: If A contains B, this is the same of having a relation "1->N on delete cascade" Another case is to use a Relation Manager. I've implemented and object Relation that is deleted when some of the two related objects are (using manage_beforeDelete). This is the same that a relation "M -> N on delete cascade" The third case I've been implemented, and the one giving me more problems, is to have a property referencing another object (path or UID). If the referenced object is dropped, the referer has problems I work a lot with ZCatalogs, using one catalog for each meta_type of objects, so for me catalogs are the most similar thing to a "Table". I'm thinking that could be very useful to implement some basic referencial integrity in ZCatalogs. Just being able to define primary keys and some simple types of foreign keys we will have on Zope the best of two worlds. Seeing code of ZCatalog product it seems not to be very difficult to implement, adding some validations on catalog_object and uncatalog_object methods. Of course, all these should be optional. I no Primary Keys neither Foreign Keys are defined, catalogs should work exactly like until now. What do you think about this ? If nobody convince me that this is a stupid work, I will try to implement it. In this case, what's the better way to provide the code ? A patch for ZCatalog ? Or a new Product IntegrityZCatalog inheriting from ZCatalog ? Thanks Santi Camps

Syslog logger broken?
by Paul Winkler 01 Aug '04

Has anybody had success with the syslog logger in Zope 2.7.0 or later? AFAICT the example in zope.conf.in is borken. See http://collector.zope.org/Zope/1425 Andreas assigned it to me, but I really have no clue how to fix it. -- Paul Winkler http://www.slinkp.com

Are input streams seekable in Zope?
by Ames Andreas (MPA/DF) 30 Jul '04

30 Jul '04

Hi, I've stumbled over some code in Zope 2.7.0 that seems to suggest that input streams are meant to be seekable. In an extension I wrote for ZServer, i.e. AJPServer, I throw an exception when this is tried and I'm quite sure the call to seek wasn't there in 2.6.x. I found the call to seek in ZPublisher.HTTPRequest.py, line 128, in method "retry". Does this mean that only seekable streams are allowed in ZPublisher (i.e. not stdin) or is this a bug? TIA, andreas
