First call to external method after restart fails
by Ted Skolnick 22 May '02

22 May '02

Hi all, I have an external method that takes 3 params. After I restart Zope ( running on Linux ), I get the following error on my first call... Error Type: TypeError Error Value: rmlToPDF() takes at least 3 arguments (0 given) All subsequent calls work fine (i.e. a refresh in my browser, and no more error, my external method works ). I restart Zope as root. Anyone ever see this before? thanks, Ted

StructuredText with Images
by Barry Pederson 22 May '02

22 May '02

I posted this earlier on zope, but I guess maybe it's more of a zope-dev kind of thing.... ------------- I was wondering what's the story with lib/python/StructuredText/HTMLWithImages.py - it looks like it should allow you to place images in structured text, with something like: "my image":img:http://foo.com/myimg.jpg but it doesn't seem to be used by default, instead plain HTMLClass.py looks to be the usual handler for STX documents, for example when calling structured_text() from within a PythonScript. I'm also curious why HTMLWithImages.document() method overrides HTMLClass.document() but takes away the option of disabling the header, and only adds a: bgcolor="#FFFFFF" attribute to the body tag (athough the version in CVS doesn't even add that). In CVS it also looks like HTMLWithImages overrides the HTMLClass.xref() method with an absolutely identical method. I'm guessing I could call it with an external method (I'm not asking for help with that) - I would mostly like to know why is it (HTMLWithImages) there separately, why isn't it being used by default, and why is it just a little different from HTMLClass in not being able to turn off the headers in the document() method.

Hello, I'm working on porting Casey Duncans ExternalEditor helper application to work with Windows. I've got some stuff working, but it's far from complete. I was wondering if anyone else was working on this? I would hate to be duplicating efforts, but I would love to help. -Brian

Is it at all productive to have .py files in the help system byte-compiled?

Presider la France en grand et autrement !
by Mailer 22 May '02

22 May '02

Chers compatriotes, Le 5 mai dernier au soir, vous vous etes tous rejouis comme nous de voir triompher, avec Jacques Chirac, les traditionnelles valeurs de tolerance et d'hospitalite de la Republique contre le fascisme au front bas, et d'abord contre l'exclusion raciste de nos amis immigres, qui ne representent - somme toute - que l'avant-garde de la misere du monde et auxquels il importe donc d'ouvrir au large, des a present, les portes de notre societe, ainsi qu'en temoigne largement l'actualite, surtout celle des faits divers. Reprenant a son compte - et a celui de la droite d'extreme centre-gauche - les meilleures propositions de la Gauche Plurielle, ce en quoi il ne faisait d'ailleurs que repondre au voeu de la quasi-totalite des Francais, le Premier Ministre, Jean-Pierre Raffarin, s'est prononce sans ambiguite - avec l'appui explicite, naturellement, du President de la Republique - POUR LE DROIT DE VOTE DES ETRANGERS. Il importe donc - en vue d'assurer le succes de cette reforme bienvenue parmi d'autres - de plebisciter les candidats de l'Union de la Majorite Presidentielle aux prochaines elections legislatives. Cet appel s'adresse surtout a vous, Francais qui travaillez et payez des impots (et qui - malheureusement - etes encore majoritaires pour quelque temps dans votre pays). Sans votre adhesion active et enthousiaste, cette reforme citoyenne serait vouee a l'echec. Vous aurez donc a coeur de repondre "Present" pour en permettre l'adoption, comme vous saurez repondre "Present" lorsqu'il s'agira d'en gerer les incidences previsibles ou non. A cette fin, vous voterez tous ensemble, tous ensemble pour les candidats de la majorite presidentielle, qui ne vous proposent ni plus ni moins que le maintien de l'excellent cap pris par la France depuis vingt ans et davantage en ce qui concerne l'integration des immigres (vous n'etes pas sans savoir combien le modele d'"integration a la francaise" fait l'admiration du monde entier). On ne saurait trop insister sur la puissante motivation que donnera aux jeunes desoeuvres des banlieues et aux malheureux deracines de Sangatte - tous en proie au racisme hideux de la population locale et aux inadmissibles brutalites d'une police de plus en plus arrogante - le fait de savoir qu'ils ne sont plus rejetes et qu'ils peuvent compter sur le soutien sans faille d'une immense majorite de la population francaise, a commencer par les forces vives du pays. Ainsi aurez-vous l'assurance, chers compatriotes, que vos impots seront bien depenses, comme il le sont deja en vacances a la neige, a la plage ou a la montagne pour les pauvres jeunes des quartiers sensibles, en attendant la generalisation et la systematisation de ce genre de mesure, qui releve de la plus elementaire justice sociale. Souvenez-vous que nous devons a Jacques Chirac le regroupement familial, qui a tant fait pour l'enrichissement du pays par l'apport d'immigres travailleurs, pacifiques, honnetes et patriotes envers leur Algerie natale ! Faites en sorte que la France s'engage enfin resolument a devenir davantage pluriethnique, multiculturelle, metissee, tolerante, citoyenne et genereuse ; faites en sorte qu'elle regarde l'avenir avec confiance : votez pour les candidats de l'Union de la Gauche de la Majorite Presidentielle ! Union de la Majorite Presidentielle, Tous ensemble avec Jacques Chirac.

ZEO & product installation Q
by Jeremy Hylton 21 May '02

21 May '02

The documentation for ZEO contains the following note about product installation. The final sentence suggests that we intend to fix it, but I don't understand the problem exactly or whether it has been fixed. Can anyone tell me if this warning is still relevant? Jeremy Zope product installation Normally, Zope updates the Zope database during startup to reflect product changes or new products found. It makes no sense for multiple ZEO clients to do the same installation. Further, if different clients have different software installed, the correct state of the database is ambiguous. Zope will not modify the Zope database during product installation if the environment variable ZEO_CLIENT is set. Normally, Zope ZEO clients should be run with ZEO_CLIENT set so that product initialization is not performed. If you do install new Zope products, then you need to take a special step to cause the new products to be properly registered in the database. The easiest way to do this is to start Zope once with the environment variable FORCE_PRODUCT_LOAD set. The interaction between ZEO and Zope product installation is unfortunate. In the future, this interaction will be removed by

Testing package & framework.py
by Stefan H. Holek 21 May '02

21 May '02

I am in the process of modifying framework.py to support INSTANCE_HOME installations of Zope. This involves a) Honouring SOFTWARE_HOME when locating the Testing package b) Adding the instance's Products and lib/python dirs to Products.__path__ and sys.path respectively You can look at a preliminary draft version here: http://www.zope.org/Members/shh/Testing/framework.py I am however unclear about the __name__ == '__main__' test at the beginning of the first half of framework.py. Is this just some kind of (redundant?) safeguard, or is framework.py actually ment to be imported (in some cases at least), contradicting the comments? And, if the latter is true, what is the second half supposed to do (or to avoid) when framework.py is imported as a module? TIA, Stefan -- BLOWFISH, n. - Preference for beef

Zope crash & restart
by Myroslav Opyr 20 May '02

20 May '02

Hi, There is installation: Zope Version (Zope 2.5.1 (source release, python 2.1, linux2), python 2.1.3, freebsd4) Python Version 2.1.3 (#1, May 5 2002, 06:29:09) [GCC 2.95.3 20010315 (release) [FreeBSD]] System Platform freebsd4 ZODB contains an instance of modified CMFSite (translated in Ukrainian, CMFSiteUA). System works perfectly well even on Zope 2.5.0 on Win32 platform but crashes on FreeBSD. Site was Exported (from Win32) and Imported (to FreeBSD). Local Filesystem View folders were deleted and recreated manually. As soon as somebody tries to touch that CMFSiteUA Zope crashes and restarts. Workaround found is: to enter management interface somwhere deeper, for example /Examples/manage or /Control_Panel/manage. Then Zope loads parts of the system into RAM and appears possibility to run the site. Sooner or later, when there is sufficient time-frame to unload all objects out of the RAM cache (no user activity), system turns back into unusable state and again there is need to bring it up with /Control_Panel/manage... Any hints? BTW, there is absolutely no output in debug mode. Just usual INFO(0) messages on startup. Crash and again usual messages. Watchdow process remains into memory but new child performing requests processinf are respawned. And again INFO(0) messages are flushed into stdout... Any help would be appreciated.

Zope/Python crashing
by Ahsan Imam 20 May '02

20 May '02

Hello, I was going through the zope archive mail and saw message posted by Matthew T. Kromer regarding crashing problems with Python 2.1.2. It instructed to increase the #define PyTrash_UNWIND_LEVEL from 50 5000000. I just downloaded python 2.1.3. Do I still have to edit the object.h file before I compile it. Thanks
