BerkeleyStorage with BerkeleyDB 3.2
by Duncan Booth 15 Mar '01

15 Mar '01

I wanted to get BerkeleyStorage installed on my Windows system. Since there is a nice downloadable binary version of the Python bindings for version 3.2, I downloaded and installed that, then modified BerkeleyStorage.py to support the new interface instead of the old one. If anyone wants a copy, see http://www.zope.org/Members/Duncan/BerkeleyStorage -- Duncan Booth duncan(a)rcp.co.uk

get_request() idea
by Tim McLaughlin 15 Mar '01

15 Mar '01

I'm making some mod's to the property sheets to allow them to fire an event (call a hook) when they change on an instance. Anyway, it looks like I'm gonna have to hand the REQUEST object all around, so I can get the data out of it that I need (as well as allow other inspection in the future). Anyway, I propose that we could make Zope internals many times simpler by having the REQUEST object available in all places Python simply by calling get_request() (a __built_in__ method much like get_transaction). This may even speed up Zope since in fact, no stack space will have to be managed for the REQUEST object to be passed to methods that might or might not need it. Cheers, Tim Please don't kill me if this is a _really_stupid_idea_.

PythonScript for iso_week
by Steve Alexander 15 Mar '01

15 Mar '01

Hi folks, At various times in the past, people on this list have asked about getting week numbers from DateTime instances. I recently had this requirement, so I wrote a PythonScript to produce an iso_week tuple (year, week_number, dow_monday_is_one__sunday_is_seven) from a DateTime instance. I've submitted the same to the collector as a feature-enhancement patch to DateTime.py. I've tested this by empirically comparing it with the output of mxDateTime's iso_week attribute for all days from 1920-01-01 to some date in the twenty-third century. Note also that this iso_week method does not create additional DateTime instances. See also http://www.cl.cam.ac.uk/~mgk25/iso-time.html -------- PythonScript iso_week Parameters: date doy=date.dayOfYear() dow=(date.dow()-1)%7 y=date.year() thurs_this_week=doy+(3-dow) is_leap=y%4==0 and (y%100!=0 or y%400==0) if thurs_this_week>(is_leap and 366 or 365): week=1 if dow<8: y=y+1 else: mon_this_week=doy-dow day_year_begins=(dow-doy+1)%7 day_of_4_jan=(day_year_begins+3)%7 monday_of_first_week=4-day_of_4_jan week=(mon_this_week-monday_of_first_week)/7+1 if week==0: y=y-1 is_last_leap=y%4==0 and (y%100!=0 or y%400==0) if day_year_begins==4 or (day_year_begins==5 and is_last_leap): week=53 else: week=52 return y,week,dow+1 -------- -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

zwiki & chinese
by Sin Hang Kin 14 Mar '01

14 Mar '01

in my current effort to try make zwiki work in chinese, i have done the following: i remove the intl_char_entities and add to _create_page: #make a new (blank) page object page = re.sub("%","",quote(page)) which make the created pageid valid zopeid (does it work all_the_time?) however, the page is created, but zwiki fail to recognize the new page and fail to link to it. can anybody help point to me where should i make further changes? moreover, is it possible to create a corresponding wikiname -> id link so the wikiname does not necessary a valid zope id? when we make editing the wiki page, is it a worth to have a list of all valid wiki name handy so we can make reference to them or avoid making an unexpected link?

Zope on OpenBSD 2.8 makes me cry
by andrew fabbro 14 Mar '01

14 Mar '01

I'm pulling out my hair trying to get Zope working on OpenBSD 2.8. I understand that there are issues...someone sent in a bug report on 1/15/2001 to the OpenBSD folks with the exact problem I'm experience. The problem has something to do with threading. I've tried 2.3.0 and 2.3.1b1 and the situation is the same in both: builds fine and starts fine, but when you try to go to /manage, python shoots up to 99% on the CPU and it never loads. I'm wondering if anyone has any ideas on how to proceed, or if there is a more recent development snapshot that 2.3.1b1 that I could try...? Also, I notice that I *have* to use python 1.5.2, not any later version. Later versions give ugly "got node 12, expected node 312" errors. I've seen some posts on deja.com that Solaris people have this problem as well. This is not a problem (I installed python 1.5.2), just want to mention it in case it's important. Thanks for any assistance! <Goes back to his caterwauling "I want my Zope" sobbing...> -- Email : afabbro(a)indoctrination.com "Don't try to be like Jackie.

Thats a really good idea, to add rsync support, but the much better way to have verson control would be having release and versions (and maybe later branches). Thats a problem with the current fs, a cvs like version expanding would be great, like <dtml-meta> <version>3</><revision>2</><release>4</> <changelog> Bugfix refererred to Bugreport #4711. </changelog> </dtml-meta> The user would be the user who had logged in, of course. The only problem of ftp is that it is not able to manage versions, I would suggest (a toggleable mode) to have a folder for each document where the versions would lie into as files (representation) for ftp. yours sincerely, Bijan Fathi

QuickTime VR Movies
by Andre Schubert 13 Mar '01

13 Mar '01

Hi all, I have found an error or bug in handling QT VR Movies with Zope. I have uploaded three qt files into Zope as File objects. I also have installed this files in the normal appache directory. Now comes the error? If i do a wget with the files from the apache directory and thi files from Zope i get always two different version of the same file. That means that a QT File that comes from Zope has a different content than a file comes from apache. The problem is that this litte difference makes a qt plugin to crash. I'am using zope 2.2.4 on Immunix 6.2(redhat). Who can help???

Permission problems
by morten 13 Mar '01

13 Mar '01

Hi guys, I've been struggling with some permission problems, and I'd appreciate some help... Being that I don't know too much about permissions (yet!), solving this issue is hard (and security _is_ hard); so I'll just point you to the problem: http://www.zope.org/Members/morphex/AddressBook/address_book-1.0.0-permissi… Just read about the SecurityClass stuff in AccessControl, but can't quite gripe that either. Anyone care to enlighten a security newbie? :-) Thanks, Morten
