Before I vanished for PyCon about two weeks ago, I was under the impression that merging Zope/branches/five-integration into Zope/trunk was imminent -- a matter of days, if not hours. Perhaps I was mistaken in that. Regardless, what's the current status of this? Last I saw, Andreas announced a plan to release 2.8a2 this coming Friday evening (according to my clock <wink>), but AFAICT the five-integration branch is still distinct from the trunk. Is it the plan to release 2.8a2 without merging this in? If not, what's the plan/schedule for merging five-integration? ZODB 3.4 requires some Zope3 packages, so there are potential integration headaches in two directions: (1) possible problems for ZODB due to five-integration using versions of those packages older than the ones ZODB 3.4 has been using; and, (2) code in five-integration that runs afoul of changes in ZODB 3.4. I can't predict these without trying the actual code. A possible example of #2 is that I rewrote hundreds of instances of get_transaction() in Zope trunks yesterday, because get_transaction() is officially deprecated in ZODB 3.4 and I don't want to release a Zope that raises DeprecationWarning in its internals. Perhaps the five-integration code has more instances of this that need to be changed. A clarification, because some have been confused about this (and it is confusing!): a ZODB trunk checkout stitches in its own copies of the Zope3 packages it needs, same as it stitches in copies of zdaemon and ZConfig. The process of stitching a ZODB into a Zope does *not* stitch those packages into that Zope: Zope uses its own copies of zdaemon, ZConfig, and Zope3 code. From Zope 2.8's POV, "ZODB" means exactly these 9 directories (these, and no others, get stitched in from a ZODB tag): Under lib/python/: ZODB ZEO persistent transaction BTrees ThreadedAsync Persistence ZopeUndo Under utilities/: ZODBTools (this is a renamed copy of ZODB's src/scripts/). I always expected (and still do) to do the ZODB stitching on Zope trunk, but since stitching in a ZODB does not include anything other than those 9 directories, I can't do it before at least the Zope3 packages are stitched in from the five-integration branch. Note that it's also possible we'll hit integration snags due to mismatches in the versions of zdaemon and ZConfig in use (the ones Zope trunk uses versus the ones ZODB has been using).

zope /tmp file usage
by Pavel Zaitsev 31 Mar '05

31 Mar '05

Hi, I am wondering what code in Zope 2.7.5-final potentially may use /tmp directory for temprorary files. I am using zope over webdav and sometimes webdav tries to create a tmp file, of some sort and some parts of the system lock up. There are xml parsers,mime decoders all of which do have binary code bits, so I asking for expert advice, if someone knows of what circuimstances zope would use /tmp directory to create a file... your help will be greatly appreciated.

Disabling FTP by default
by Florent Guillaume 31 Mar '05

31 Mar '05

I'd like to disable FTP by default, by commenting it out in skel/etc/zope.conf. The reason is that it's better to open as few ports as possible by default. Opinions ? Florent -- Florent Guillaume, Nuxeo (Paris, France) CTO, Director of R&D +33 1 40 33 71 59 http://nuxeo.com fg(a)nuxeo.com

But in the zope 'Add' list, I can't see any of the additionally installed components, including 'Plone Site'... I tried restarting zope, my browser and also the system.. Any tips? Regards, JV

More robust cookie handling
by S.Aeschbacher 30 Mar '05

30 Mar '05

Hi during some testing I did I stumbled over this problem. When a client which is accessing a page on a Zope server sends a _ZopeId with other spelling (e.g. _ZOPEID). Zope does not accept the cookie and (obviously) sends a new value in the answer. According to RFC 2965 and RFC 2109 (defines the Set-Cookie header but is obsolete by RFC 2965) the NAME part of a name-value pair is treated case-insensitive. I'm not sure if this is a issue worth bothering as all user-agents seem to leave the NAME part intact (except my self-written test-suite ;). Changing the behaviour to ignore the case of the name would make it somewhat more robust. If you think it is worth bothering I will open an Issue in the Collector. regards Stefan

Re: [Zope-Coders] Re: Question about procedures

[moved from -coders to -dev] First off: I will go with Lennart's suggestion of branches; I fundamentally agree; I have just never worked on a project where branches for such petty things aren't overkill. I guess Zope is a number of magnitudes larger. :) Now sorry for the noise on zope-coders when this should have been on zope-dev in the first place. Now for some of the things that Florent pointed out: also sprach Florent Guillaume <fg(a)nuxeo.com> [2005.03.24.1814 +0100]: > > - if RESPONSE is not None: > > + if RESPONSE is not None and ob: > > You should check 'and ob is not None' too. ... but ob is false when it is None, no? > But why could it be None ? What's the point (sorry I don't have > context). Well, I was trying to guard against errors made in other parts of the code. I know I should not do this. It made things a lot easier while I was preparing some other patches. Anyway, good thing I haven't committed. :) > > + if not hasattr(ob, 'absolute_url'): > > Do not use hasattr for persistent objects. Use > if getattr(ob, 'absolute_url', None) is None: Can I read up on the rationale somewhere? > > + raise TypeError('constructInstance did not return a CMF object.') > > Also, check your indentation (should be 4 chars). Woops. > > - return ob.getId() > > + return getattr(ob, 'id', None) > > Please don't do that, getId() is the proper API to call. Another instance of "what to do when ob does not have an getId method".. you are right, this is wrong. also sprach Andreas Jung <lists(a)andreas-jung.com> [2005.03.25.0945 +0100]: > For changes which are limited to a file or a subtree I do always > prefer a patch instead of a branch. I can create a branch and submit patches to you (this is when I wish zope.org would be using GNU arch). Anyway, since it's probably best for me not to make changes in the code at present time (being young in the project and without an assigned field of responsibility), where do I send potential patches?
