Re: [Zope-dev] Re: Post-mortem [Was: Zope 2.7.0 b3 regressions]
From: Evan Simpson [EMAIL PROTECTED] Lennart proposed additional methods, but I'm going to work on that in the post-2.7 branches, since I really want to clean up this mess properly, and beta 3 isn't the time. I totally agree. This is new features, introducing that in a beta3 seems very bad. I proposed introducing them in 2.7 only to: 1. Get things moving by scaring people. :-) 2. A way of fixing absolute_url by making it's bugs less important. If absolute_url can be fixed so it doesn't break backwards compatibility, then number 2 is of no importance. //Lennart ___ 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 )
Re: [Zope-dev] ZOPE + SSL
Another solution (although I've not actually used it) is the load balancer Pound by Robert Segall in front of Zope. Pound has explicit Zope/SSL support.

ZOPE + Apache + Apache mod_ssl + openSSL + Virtual_Host(or similiar solution)? Is ok, but it is not a little bit contradictory to need to use a second Web Server for supporting the first one? Redirecting URLs, and all... Dunno, there would be a day where ZOPE could have it's own support? ZOPE + OpenSSL + M2Crypto + SWIG? (this one rewrites Zserver parts) Is a little bit tricky to handle with the building, and i've found many exception problems when using it, especifically in BIO access types. Looks like the error handling is not very improved. ZOPE + OpenSSL + pyOpenSSL? This needs to be integrated in ZOPE, as a product, or anyway. Is there a most used recipe or case study examples?

The default Zope setup has two databases: the main database and the session database. So it's not completely nonsensical for any default-configured Zope to raise the error (although I have no idea how this error is occurring). It might be worthwhile to specify a main database explicitly in zope.conf. This will prevent the default database setup from being invoked and then you will be sure that you only have one database connection.

Re: [Zope-dev] To the brave folks trying Zope HEAD...
Actually, there are two equally valuable clues from the debugger session: object : class 'Products.Formulator.StandardFields.LabelField' type: ExtensionClass.ExtensionClass refcount: 7 address : 0x8503bec If I understand correctly: LabelField is a class that inherits from Persistence and some other object has a reference to it that isn't via __class__. persistent.Persistent._p_jar attribute '_p_jar' of 'persistent.Persistent' objects If you ask a class for an attribute, it seems you can get a descriptor back. I vaguely recall Guido saying that this was the intended behavior last time I asked about it. 'jar' gives: object : attribute '_p_jar' of 'persistent.Persistent' objects type: getset_descriptor refcount: 2 address : 0x40621e6c Thus, asking for the class's _p_jar gives the descriptor back. In ZODB4 I hacked around this by requiring that the value of _p_jar be None or a string. Would there be any objection to having the same requirement in ZODB3?

We can check that an oid is a string or None, but not a jar. I'll have to think about an efficient check.

[Zope-dev] zopectl start not working on Mac OS X
We are planning on shipping Zope 2.7 with the Plone 2 installer for Mac OS X. I can start a Zope instance on Mac OS X 10.2.8 using $INSTANCE_HOME/bin/runzope, but not using $INSTANCE_HOME/bin/zopectl start. I'm using Python 2.3.2 built from source, and Zope was built using: ./configure --with-python=/Applications/Plone2/Library/Software/Zope270/Python/bin/ python --prefix=/Applications/Plone2/Library/Software/Zope270/Zope --optimize make make install (note, the same thing happens whether or not i use the --optimize option) This happens with b3 and Zope-2_7-branch from today. cd $INSTANCE_HOME ./bin/zopectl start Traceback (most recent call last): File /Applications/Plone2/Library/Software/Zope270/Zope/lib/python/Zope/ Startup/zopectl.py, line 215, in ? main() File /Applications/Plone2/Library/Software/Zope270/Zope/lib/python/Zope/ Startup/zopectl.py, line 198, in main c.onecmd( .join(options.args)) File /Applications/Plone2/Library/Software/Zope270/Python/lib/python2.3/ cmd.py, line 210, in onecmd return func(arg) File /Applications/Plone2/Library/Software/Zope270/Zope/lib/python/Zope/ Startup/zopectl.py, line 134, in do_start ZDCmd.do_start(self, arg) File /Applications/Plone2/Library/Software/Zope270/Zope/lib/python/ zdaemon/zdctl.py, line 214, in do_start os.spawnvp(flag, args[0], args) File /Applications/Plone2/Library/Software/Zope270/Python/lib/python2.3/ os.py, line 543, in spawnvp return _spawnvef(mode, file, args, None, execvp) File /Applications/Plone2/Library/Software/Zope270/Python/lib/python2.3/ os.py, line 504, in _spawnvef wpid, sts = waitpid(pid, 0) OSError: [Errno 10] No child processes I added code to zdctl.py to print out the environment and the command line used in os.spawnvp.

If you have any suggestions for ways I can debug this further I can go further on this. For now I think I'm going to have to stick with runzope... but I'd really like to be using zopectl start/stop/status instead.

[Zope-dev] Preview of a Stackless Zope Application
Howdy, I made a little demo of Stackless Zope. It is just a quick hack to see how things can work. The example is a long-running Python method which prints lines to the browser. The key to this surprizing solution is tasklets, channels, and thread pickling.
