Some patches..

Couldn't find the right place to submit'em, so here they are.. DT_Util and DT_Var are fixed to escape characters that break javascript and tclscript strings. DTMLMethod has a hack that let's us edit files via the composer which is part of the Netscape Communicator package, for examples go to emm.src.no/dirigent (may not be updated yet) -Morten W.

BooleanIndex for ZCatalog?
by Alexander Limi 24 Mar '00

24 Mar '00

Hi. I would like to suggest the following addition to the ZCatalog code: A BooleanIndex type in addition to the existing FieldIndex, TextIndex and KeyIndex. The reason behind this is that Zope stores boolean 1 as "on", whereas a lot of other sources store them as "True" or simply "1". I ran into this problem when trying to catalog values that other programs had set in the ZODB. Some of them appeared as "on", some as "1", and yet others as "0". The last one was the one causing the trouble, as it was per Zope definition true, even if the value indicated false. So, I thought I would suggest that the catalog does some interpreting of the result when indexing boolean fields, setting the values "off", "0" and "false" to None, and not just do a pure "index what's contained in the field" like it does now. This would IMHO best be done with a new Index called BooleanIndex. If this sounds totally unacceptable, feel free to ignore my post - I'm a clueless newbie relaying my initial problems to the zope list as I find them :) Regards, Alexander Limi PS: CC any answers to me, as I'm not really qualified to be on the zope-dev-list :)

Re: [ZIP] dtml-str idea

Hi all, Note: I cc this message to zope-dev because I want to be sure that the DC folks get aware of this, since I think internazionalization support should be a standard Zope feature, so their opinion is *very* important. First, I've just uploaded the vocabulary product to Zope.org, download from "http://www.zope.org/Members/jdavid/vocabulary". Now a brief description of the vocabulary python product. It is really simple, the data structure is a dictionary indexed by strings which contains another dictionary indexed by language which contains the translations, example: {'window': {'en': 'window', 'es': 'ventana', 'ca': 'finestra'}, 'house': {'es': 'casa'}, ... } It also provides a web interface to edit the entries and translations, visit "http://estce.act.uji.es/zope-edu/LLEU/V/manage_workspace" to see it. And more, it has XML support, you can export/import its contents to/from XML files. Just click in the "XML" tab to see it. It's used in this way (if the product instance is called "V"): <dtml-var "V('window')"> The language is determined by the variable "languages" which must be a sequence of languages, for instance it could be a Folder property of type tokens with value "en es ca". First the translation is searched for the first language ('en' in our example), if it's found that translation is returned, if no it tries with the next language, if no translation is found it returns the original string. Hi Shane, First, please excuse me because my yesterday comments were so short, writing good english messages takes time for me. Your proposal is a different approach to the problem, and I think both solutions complement each other. The vocabulary product is more flexible because you can use it from any place (not just DTML Documents) and it also allows to share common translations. The solution you propose is specially useful to translate long texts which are unlikely to be found in more than one place. And since the contents between the "dtml-str" tag could be very dynamic it also opens the door to automatic translators. > > Hi folks!

Re: [Zope] reall-time data to a Java client interface from ZOPE
by Performance.net Support 24 Mar '00

24 Mar '00

That's definitely the idea. I've been reading up on ZOPE and Medusa and this type of thing is is exactly what they were designed for. What I'm wondering now is, is it possible to plug a server I write into ZOPE in the same way that FTP is plugged in, as a behind the scenes service that starts when ZOPE starts. If so, how is this done? Are there any docs that might give a bit of detail on this subject? kh ----- Original Message ----- From: "sam" <linuxcraft(a)redspice.com> To: "Kevin Howe" <khowe(a)performance-net.com> Sent: Monday, March 20, 2000 9:37 PM Subject: Re: [Zope] reall-time data to a Java client interface from ZOPE > On Sun, 19 Mar 2000, you wrote: > I can think of some possibilities.

Aye carumba, I haven't even been following this thread, not the most useful subject line! Ok, it looks like there are two issues: 1) some sort of FCGI issue which I do not have the capacity to reproduce 2) the same stability issue I am currently looking into. The problem with 2) is that no one can reproduce it reliably (this may not be true after I look at something someone sent me today, I'll keep everyone updated) including myself. I have pounded a half dozen sandboxes with ab for hours and gotten nowhere. No crashes. Not a single burp. I'm, of course still looking into this, but I need more data from the folks out there. First of all, if you suspect that your Zope is dying and restarting alot, run it in debug mode like this (unix only, sorry): bash$ strace -f -e trace=none -signal=all python z2.py -D See 'man strace' for the gory details. obviously tune the parameters to z2.py to suite your needs. What we are looking for here are SIGSEGV. You'll probably see a lot of SIGUSR1s, these are normal. If you can get a SIGSEGV to happen reliably, _please_ let me know. -Michel
