Re: [Zope-dev] when did transaction lose the ability to be usable as a context manager?

Much better just to change the code to define an object and import that from the module. ___ Zope-Dev maillist - Zope-Dev@zope.org https://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope )

The existing installer atempted that but I don't believe it was very successful. I would like to know if anyone has multiple Zope installations on Windows side-by-side and if they consider that important. Yes and yes. Same as Martin Aspeli's reasons: testing on multiple plone versions. I think the main thing is to be sure that the installation doesn't add any zope specific folders to PythonPath in the registry. The Plone installation for example adds (or added) some folders to PythonPath which meant that multiple plones using the same major python version would try to share parts of the Plone installation. Not adding folders to the pythonpath registry key allows coexistence, and there are more than enough ways to add folders to pythonpath without using the registry. ___ Zope-Dev maillist - Zope-Dev@zope.org 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 )

Chris McDonough wrote: There's a nice little Mac freeware app named IcoMaker for creating .ico files from GIF files. .ico files are actually containers for various icon sizes and color depths and this app allows you to create an .ico file out of up to six sizes/depths. I stole the favico from zope.org and made one using IcoMaker with a single size/depth (16x16/16colors). It's attached. I haven't tried it in IE. If it doesn't work for whatever reason, maybe someone else who has more icon-foo can do a more thorough job. That one works, at least in those cases where IE is displaying the icon at 16x16. Some higher resolution images in the file would be useful though for situations where it decides to display larger icons, otherwise it looks pretty blocky. So far I've found at least 4 different icon sizes used in IE and one outside. From smallest to largest: address bar and favourites toolbar are smallest (1), the links toolbar uses a larger icon (2), favourite properties has the icon on two tabs in different sizes 'web document' (3) and 'General' (4). And of course IE's favourites are actually just a folder, so you need a suitable icon for Explorer's icon view (5). I haven't measured these, but I would guess the sizes I saw were 16, 24, 32, 48, and 64 pixels. There's an icon maker at http://favicon.ru/en/ which will do 16,32 and 48 pixel images online, but I don't have a decent starting image. ___ Zope-Dev maillist - Zope-Dev@zope.org 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 )

[Zope-dev] ZEO question.
And now onto the reason I was looking for that list: -WinNT 4.0 -Zope 2.3.1b1 -ZEO 0.4.1 E:\Zope\2.3.1b1python lib/python/ZEO/start.py -p 8000 Traceback (innermost last): File "lib/python/ZEO/start.py", line 315, in ? if __name__=='__main__': main(sys.argv) File "lib/python/ZEO/start.py", line 297, in main signal.signal(signal.SIGHUP, handler) AttributeError: SIGHUP What does that mean and how can I fix it? It means that ZEO isn't compatible with NT. simply comment out line 297 of start.py and it should be fine. Finally, how can I get the storage server to use the Data.fs from my INSTANCE_HOME rather than the SOFTWARE_HOME, which I presume the above does? I think the default is to use INSTANCE_HOME/var/Data.fs so you should be happy. BTW, I have managed to get ZEO running as an NT service complete with Core Session in a mounted BerkeleyDB 3.2 storage. -- Duncan Booth [EMAIL PROTECTED] ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Yes, you have to change line 310:
open(zeo_pid,'w').write("%s %s" % (os.getppid(), os.getpid()))
to:
open(zeo_pid,'w').write("%s" % (os.getpid()))
I have posted a report on the ZEO Tracker for both these changes.

[Zope-dev] BerkeleyStorage with BerkeleyDB 3.2
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.

On 15 Mar 2001, you wrote in local.zope.dev: Matt wrote: select should have a corresponding /select right? In which case no, it should not have a trailing slash. They are only needed for single tags that have no corresponding close, eg br / hr / etc. I agree but in the management interface of Zope it's not the case. You have select ... / Some stuff... /select and you should have select stuff /select. That's the reason why it doesn't work anymore with Mozilla. It just seems to be one place in zope's code.

Re: [Zope-dev] Repeating a piece of HTML code
dtml-in expr="_.range(0, movie_rating)"
img SRC="star.gif" height=15 width=15
/dtml-in
Replace movie_rating with the variable that represents the movie rating.
What about dtml-var "'*' * movie_rating" ?
Fine, except that he wants the img tag repeated the appropriate
number of times. Try putting the tag into the dtml-var statement
and you get something along the lines of (untested):
dtml-var "('img src=%sstart.gif%s height=15 width=15' %
(_.chr(34), _.chr(34))) * movie_rating"
at which point the dtml-in starts to look more appealing.
Of course if you rename star.gif as star_gif you could try:
dtml-var "start_gif.tag() * movie_rating"
which has a certain neatness.
