Re: [Zope] Using Chinese Characters

There're also Unicode CJK and GB. But GB is for China, which uses simplified chinese characters. And CJK includes both Big5 and GB. classic zope is built on python 1.52 and does not naturally support unicode. But there is a light on the horizont: http://www.zope.org/Members/htrd/wstring I have a vision of everything working together for localizing and internationalisation ;-) It's good to finally see some Unicode support coming through. I'm a bit surprised that Guido didn't mandate Unicode support from the beginning, given that Python is a relative newcomer to the programming scene. I imagine Python 2 will have full Unicode support, right? Or is it already in Python 1.6? Bad news is that Unicode is not good enough. It allows for about 64k characters, yet Chinese alone (Han ideographs) has over 75,000 (maybe a lot more, but that includes old, rare and uncommon characters). When will we see support for UCS (Universal Character System, ISO 10646) which uses (up to) 32 bit (31 bit?) characters. As far as I know, at present the only UCS characters currently defined are those defined by Unicode (about 40,000 of them), but we should be supporting it now in readiness for the future. Food for thought. Zai jian! (Too bad email is plain ASCII or I could use the proper characters!)

Not all countries use the american form of dates, so it would be nice to have a standardized one (in my opinion this applies also to the standard date functions in Zope). The reasons for establishing ISO 8601 apply here as well: - ordering of month and day are different in Europe and America, this leads to difficulties interpreting date values - ISO dates are sortable by string functions - ISO dates are easy to parse by humans AND programs Opinions? I agree. If everyone standardised on ISO 8601 in written date and time formats, the world would be a saner place. Writing MM-DD-YY(YY) is just silly in my opinion, no matter how you like to say it out loud. It may have been acceptable in times past (like when the Internet was not nearly globally ubiquitous), but these days it's just an anachronism (as is DD-MM-YY, because it is easily mistaken for MM-DD-YY).

I have a custom error page in Zope (2.1.6), but Zope wants to put the traceback information into an HTML comment at the foot of the page (which I don't want to have there). I set BOBO_DEBUG_MODE=0 and exported it in the "start" script, and also removed the "-D" from the command line that launches Z2.py. I thought that was all there was to it, but there must be something else that I've forgotten. Just removing the -D flag should do it. It may be that just having 'BOBO_DEBUG_MODE' defined (whatever the value you set it to) triggers debug mode, so defining 'BOBO_DEBUG_MODE=0' may well set Debug Mode on :) I think what David means is that, when not in debug mode, Zope appends the error in HTML comments to the end of the HTML stream. There was a thread on this not long ago and, IIRC, this was found to be hard coded into Zope. OK, looks like some Zope hacking to do... :-( My own view is that Zope shouldn't stick any error messages into or on the end of error reports. At best, it's bad HTML, at worst it's a security risk (the python traceback includes the full paths of the files on the machine...) If you want an error report/traceback, you should specifically include it in standard_error_message. Agreed. It's just plain dumb (not to mention embarrassingly unprofessional) to put content after the /html tag. My main concern, though, is the security aspect. The less potential crackers know, the better. At the very least, a traceback like that says: "Hey, this is a Zope site." To which the wiley cracker replies, "Great. Now lets try all the known Zope vulnerabilities." Obviously, security by obscurity is not a good idea, but obscurity is not a bad idea, either :-) Apart from all of that, there is the issue of content being added that wasn't requested. That's a bit impolite, I think. Has anyone put this in the collector, or is it more suited to dev.zope.org? I'd classify it as a bug for the collector, myself... I think there's also a related issue of a hard-coded error message page in the guts of Zope somewhere, because the user-defined error page is not used in every case... cheers, Chris Sorry for the whinge, guys and gals!

[Zope] Speeding up Zope by disabling logging of hits
I'm using zope behind a front-end server and don't require any logging of hits. Is there a way to disable Zserver hit logging to increase speed and decrease disk utilisation?

You won't see the problem until you try to import the module, as seen above. so is there anyone here who can suggest how I might fix this? (By the way, the compile went through without a problem, and there was a -lcrypt on the appropriate Setup.in line). One other thought. The first time you run: make -f Makefile.pre.in boot a Setup file is created. If you then change Setup.in, you need to delete Setup and re-execute the above line. Otherwise, the changes won't be reflected. Jeff hit the nail on the head with that one. I've replied to him personally and thanked him. What I had done was inadvertently run the make -f before I had edited the Setup.in file. I then edited the file as I should have and re-ran make -f without realising I had to delete the file called "Setup". Ignorance is a curse.

In our company we are currently working to create a Web site with lots of dynamic content, database access, webmail, etc.. so we decided to try Zope. Although it's lack of documentation ( this would not be fair, with a search engine we can dig out lots of useful info from the web) we experienced a very fast development cycle. Now we're concerned about its stability. We are almost finishing the first stage of project and some times Zope hangs. It was working ok, and then, all of a sudden, it just stops answers requests. Last time it happend we changed a DTML Method to a DTML Document and it worked again (if you like i'll try to tell you exactly what was happenning). So, I'd like some advice to make it more stable.

We aren't doing any database connections on it (through Zope, that is), but we are running Squishdot (which is the main application in terms of usage on this particular machine). Zope is running behind Apache 1.3.9, and I noticed that multiple instances of Zope.cgi started up to service incoming requests, but apparently Zope wasn't responding. I just restarted Apache and everything was fine again. Is this a known problem with Zope that has been addressed in 2.2? Thanks.

Hi David,
I just posted something similar to Zope-Dev:
http://lists.zope.org/pipermail/zope-dev/2000-July/005744.html
Thanks for that. I actually worked out a fairly similar hack myself, which
only did one folder (which was OK for the particular task that I wanted it
to do). Your recursive method has no doubt saved me quite a bit of time in
generalising it. There are still a couple of little question marks in my
mind, though. But before I get to them, I'll just post a sample of what I
came up with (minus most of the gory details of the actual processing I
wanted to do:
def processDTML(self):
"""Process DTML documents within a folder."""
import re
myregex = re.compile(r"(H1.*?/H1)")
thisdoc = self.getFirstChild()
while thisdoc is not None:
if hasattr(thisdoc, 'meta_type'):
if thisdoc.meta_type == 'DTML Document':
# Do processing stuff here
doctext = thisdoc.raw
doctext = myregex.sub(r"\1\n\nH2Profile/H2\n", doctext)
thisdoc.raw = doctext
thisdoc = thisdoc.getNextSibling()
return 'Complete!'
Just for easy reference, this was what you came up with:
import re
def convert_dtml(self):
"""Convert DTML Methods and DTML Documents from old syntax to
new syntax.
Warning: recursive!
This assumes that DTML Method and DTML Document haven't been
subclassed.
"""
print 'convert_dtml: id=%s' % self.title_and_id()
if hasattr(self, 'meta_type') and \
(self.meta_type == 'DTML Method' or \
self.meta_type == 'DTML Document'):
convert(self)
# should this be "isPrincipiaFolderish"?
if hasattr(self, 'isAnObjectManager') and self.isAnObjectManager:
for v in self.objectValues():
v.convert_dtml()
_convert_regex =
re.compile('''!--#(/?)(([^"-]+?|"[^"]*?"|'[^']*?'|-[^-])+?)--''')
def convert(dtml_item):
print 'converting...'
title = dtml_item.title
# like document_src, but doesn't require RESPONSE
data = dtml_item.PrincipiaSearchSource()
print 'data'
print data
newdata = _convert_regex.sub('\g1dtml-\g2', data)
print 'newdata'
print newdata
print 'end'
dtml_item.manage_edit(newdata, title)
Some questions I have in my mind:
1. I used "raw" and you used "PrincipiaSearchSource()" . The reason I used
raw was because I wanted to be sure that what I got wasn't munged in any
way, and that what I put back reflects what was actually there before.
2. You used the "manage_edit()" method, whereas I just assigned to the
"raw" property. My way seems to work OK, but I'm not sure how yours works:
I assume it brings up an edit page in the browser for each document?
3. I don't like resorting to testing the "meta_type" for a particular
string value. As you noted in your code, it doesn't allow for subclassing,
so it's not fully general.
4. I was surprised that the import statement (not to mention
"re.compile()") could be put outside of the method definition, considering
that Zope's external methods grab on to individual methods within a Python
module.
