[Zope-dev] transience and gc.set_threshold(1)

[Zope-dev] Documentation
Im a little out of touch with Zope development these days; Ive been focussing on non-zope projects for the last year or so... I have some Zope documentation on http://www.zope.org/Members/htrd that I am no longer able to maintain, but wich generates a steady stream of emails with questions and change suggestions. In particular, my notes on using squid with zope, and the changes I originally drafted for the Zope Developers Guide on using unicode in Zope. Is there now a more approporiate place to hold this documentation where it can be maintained?

[Zope-dev] PageTemplate XML mode bugs
Hi! There are two annoying bugs that make the XML mode unusable for many tasks: - http://collector.zope.org/Zope/1101 (i18n namespace broken) - http://collector.zope.org/Zope/1474 (XML files opened in binary mode) I would volunteer to work on these issues, but for that it would be useful to know: 1.) Does anybody feel responsible for the TAL or PageTemplates module? 2.) What was the motivation for the original code? #1101 looks like someone just forgot to remove a debug assert in TALParser.py. The Zope3 version doesn't have that assert statement. Or was there a reason to disable i18n for XML mode? #1474 is a change backported from Zope3. It was reverted for HTML mode for apparently the same reason why the XML mode is still broken. I guess the motivation was to preserve CDATA, but I don't know that for sure.

[Zope-dev] Conditional imports in ZTUtils/__init__.py
ZTUtils/__init__.py contains code like this:
if sys.modules.has_key('Zope'):
# import things
This is causing me repeated headaches when writing tests, because it
assumes/dictates a certain module import order. Can this go away,
please? I mean we know we are running Zope, don't we?
If there are no objections I will remove the condition on 2_7-branch
and trunk. Tests pass just fine without it.

That is a nuissance. It's unfortunate we still don't have any sort of common type system for bytestreams that's supported in filesystems. But disk files aren't the only source of bytestreams, so that doesn't necessarily help us in the end. Arent there any libs for python to examine the contents (usually the first few bytes) for the type of the file? I'm not aware of any for the general case. There are a few things like the imghdr module, but those are not for arbitrary files, and likely aren't sufficiently capable. I think there's a library from the Gnome desktop project for this (basically providing something like the Unix file command), but I don't know if there's a Python wrapper for the library, or an all-Python re-implementation. -Fred -- Fred L.

This is part of my attempt to allow the various bits of ZPT to work
outside of Zope. It assumes that the presence of the 'Zope' module is a
reliable test. Perhaps this is a YAGNI, or perhaps there's a better way
of accomodating non-Zope users.

I ran the tests above in a loop a few hundred times on my box just now, with no failures, Python 2.3.4 and command line: test.py -vvLd -g1 --dir lib/python/Products/Transience/tests . testPathological There's a big difference between my runs and yours, though: running the two tests took about 4.6 seconds on your box, but takes about 1.8 seconds on mine. Now, for example, if I add oldtime.sleep(3) # approximately 4.6 - 1.8, on the high side right before map(self.t.__delitem__, r) in testPathologicalRightBranching, then testPathologicalRightBranching fails every time in a way similar to your reported failure -- and even without -g1 on the command line. If I change the sleep to 1.5, then (with -g1 again) sometimes it passes, sometimes not, depending on how busy the box is doing other stuff at the same time. So that's A Problem. Any test that adds a bunch of stuff to a TransientObjectContainer and expects to *find* it all there later is implicitly assuming that the test runs fast enough so that containees don't vanish before their containedness is checked. I suspect you're seeing problems with -g1 here just because -g1 grossly slows the tests. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

I've been recommending people wanting to use page templates outside of Zope use the version from Zope 3. I've not had time to follow-up with the people that have been experimenting with it, though. The code in ZTUtils' __init__.py is scary, partly because of the import-order issue. If the condition should remain at all, it should be implemented using the usual pattern:: try: import Zope except ImportError: # extra stuff goes here ... The assignments could be made non-conditional without introducing problems, so they should be. I'm not sure what the intent of the additional imports is; that seems very strange since there's no alternative implementation if the Zope package hasn't been imported. -Fred -- Fred L.
