virtual zope hosting

hi! i am using apache 1.3.3 and zope 1.10b3 and want to set up virtual zope servers, where each server gets its own sub directory within the zope file system. if you access such a virtual server, however, the path to the server's root within the zope file system is added to the base url of each page. i've tried to trick zope to use the correct path using mod_rewrite, and failed. is there a workaround available or a way to modify the zope server to do the trick? thanx in advance, basti --------------------------------------------------------------------- sebastian f. luehnsdorf beehive elektronische medien gmbh --------------------------------------------------------------------- http://basti.beehive.de http://www.beehive.de mailto:basti@beehive.de mailto:service@beehive.de fon: (+49 30) 84 78 20 fax: (+49 30) 84 78 22 99

Making Zope international
by Thilo Mezger 22 Jun '99

22 Jun '99

hi! there are a couple of details that make zope a little bit inconvenient when using it outside the US. for example:  will output: $10,000.00 if you want to develop software for non-angloamerican countries and want to output monetary values you usually want something like this: fl 10.000,00 (Dutch guilders) DM 10.000,00 (Deutsche Mark) 10.000,00 F (French francs) L. 10.000,00 (Italian Lira) please mind the different use of "," to seperate decimals and "." to seperate thousands and the currency symbols before or after the money value. this is how most continental european countries format money values. in addition, the available output formats for the DateTime object (aCommon, fCommon, etc.) are not suitable for use in continental europe. for example, in germany i would like to have a format to output a date like this: "22. Juni 1999" or "22. 06. 1999". writing zope products that behave according to these local conventions is quite difficult. on the other hand, i think making zope aware of the locale system that is available on most unix systems shouldn't be this hard. therefore, i'd like to suggest the creating of ZIP - the ZOPE INTERNATIONALIZATION PROJECT instead of asking DC to implement the features mentioned above a couple of volunteers could develop some more output methods for the DateTime object and expand the money output methods to behave more internationally. strictly keeping the new version compatible with the old one of course. later, these code contributions might be merged with the official zope if DC approved the changes. i already have a couple of ideas but i'm still looking for a couple of people (preferably from different european countries) to discuss and implement these i18n functions. suggestions? comments? volunteers? thilo

This is unfortunately a much hairier problem than it first appears - for one thing, you do not _truly_ have internationalization without unicode, and the use of unicode raises huge architectural issues - just ask Guido :) These issues go very deep. The string-sig has been working to find some reasonable answer to the unicode dilemma - hopefully the end result of their work will provide a reliable basic level of built-in unicode support that could be used as a starting point for thinking about internationalization. It would be a good thing for one or more champions in the Zope community with an interest in this to start capturing some things such as: o a laundry list of requirements or use cases describing the kind of internationalization support we think we need (e.g. "it should be possible to read and render a file-based DocumentTemplate written in unicode", "it should be possible to create and store a unicode DTML Method", etc.). o a laundry list of known or possible issues related to internationalization. If some folks can get the ball rolling by starting to capture these things, maybe can create something like an internationalization SIG on the new Zope.org that's coming soon and let the SIG champions maintain and evolve those artifacts on the site. If nothing else, this would keep these concerns from being washed away in the raging rapids of the mailing lists...

Win32: BUG + FIX
by Anthony Pfrunder 22 Jun '99

22 Jun '99

Hi, I've finally fixed the corrupted database problem on Windows. This occurs when you delete Data.fs and involves the transation engine not correctly initalising the database when it is created. This results in all records having the same datetime, hence causing lots of problems. This patch works by manually setting the create flag if the file doesn't exist. Also, directly after writing the first record it closes Data.fs allowing it to be re-opened to read the (now existing) first record. The patch: ******************************** Cut here ************************** File: \lib\python\Zodb\FileStorage.py: line 195 class FileStorage: _packt=0 _transaction=None _serial=z64 def __init__(self, file_name, create=0, log=lambda s: None, read_only=0, stop=None): + # Windows database hack: + # if db file doesn't exist then set create mode + if not(os.path.exists(file_name)): + create = 1 if read_only: if create: raise ValueError, "can\'t create a read-only file" elif stop is not None: raise ValueError, "time-travel is only supported in read-only mode" # Now open the file ************************************ Cut here ************************* File \lib\python\Zodb\FileStorage.py: line 248 if create: if os.path.exists(file_name): os.remove(file_name) self._file=file=open(file_name,'w+b') self._file.write(packed_version) self._pos=4 self._oid='\0\0\0\0\0\0\0\0' + # was return, instead, close file and allow it to be reopened + file.close() Cheers, Anthony Pfrunder

ZODB3 Q
by Clint Shelby McCulloch 21 Jun '99

21 Jun '99

A few Q's on the new ZopeBase for any takers. 1) ZODB3 supports multiple concurrency. Does this mean that an application can have transactions running on different threads AND multiple application processes may be running? If the latter is possible, is it possible using the present ZODB classes (I noticed there was one for 'distributed filestorages') or possible only by supplementing them in some way? 2) Can ZODB be easily used independently of Zope? Is there any sample code for such a thing?
