[Zope-dev] git mirror of svn://svn.zope.org/repos/main ?

[Jeff Kowalczyk]

I was going to ask this question anyway, but perhaps it's more timely with
the scheduled server move:

Has anyone made a git clone of svn://svn.zope.org/repos/main suitable for
public mirroring on github, etc.?

[Zope-dev] Re: Zope on Python 2.5?

[Jeff Kowalczyk]

Would it be possible to have a non-system python installed (by default
into /opt/python24) by the system python easy_install? I think it would be
useful to have eggs that provide commands on the path such as
easy_install_nonsystem24, virtualenv_nonsystem24, python_nonsystem24. With
a better spelling, of course.

Perhaps if non-system pythons were packaged in a way that setuptools could
install them, they might become ordinary dependencies of Zope/Plone eggs,
which could detect and configure to use them in a virtualenv at setup
time.

I don't know if setuptools is currently capable of installing packages
completely separate from the running environment, or executing another
python during setup. However, It seems to me that the most expedient way
to encourage widespread use of non-system python is to make them available
as a dependency for applications and frameworks that prefer them.

After my distribution (Gentoo) updated to python2.5, I made the overdue
switch to a buildout-based non-system python. I greatly appreciate the
fact that it has no packages installed and never changes, obliging me to
use buildout or virtualenv always.

I'd like to have the best-practice setup available as an easy_installable
package. On my distribution, tools are already available to package
complete/correct PyPI entries.

Thanks.

Yes, that's what I meant to ask for, PILwoTk-1.1.6.3 to PyPI as a source
release. I'm currently using
http://download.zope.org/distribution/PILwoTk-1.1.6.3.tar.gz

 A more interesting questions is whether the source release should be
 uploaded.  I wish someone could convince Fredrik Lundh to make a saner
 release of PIL. Maybe someone could pursue this on the image- sig
 mailing list (http://mail.python.org/pipermail/image-sig/).

Yes, that's what I was hoping to avoid asking ;) since I don't know the
PIL packaging rationale. The effbot.org release pages are so thorough, I
presumed that PIL was going to continue to be packaged as-is.

Thanks.

[Zope-dev] PILwoTk egg to PyPI?

[Jeff Kowalczyk]

Would someone be willing to add the PILwoTk-1.1.6.3(-py2.4-linux-i686).egg
to PyPI?

If PILwoTk becomes a PyPI entry, I'd like to ask a follow-up on the Plone
list to see if ploneout buildouts can/should by default depend on PILwoTk
to satisfy Plone-3.0's PIL dependency.

I'm able to use PILwoTk for this purpose while still running from a python
with no installed pacakges, making ploneout very easy to use.

Thanks.

[Zope-dev] Twice-annual releases and bugfixes?

I'm building from svn, so it doesn't make much difference to me, but I was
curious whether the circumstances (if any) that would trigger bugfix
releases were documented anywhere.

I can't recall clicking on top frame of the ZMI or a 'Help!' link in the

to rip out locally installed static help facilities, and spend the effort

[Zope] SiteAccess (Enh. VHM) still needed, or merged to Zope?

[Jeff Kowalczyk]

Most references I find (google, The Plone Book - McKay, Building Websites
W/ Plone - Cooper) on virtual hosting Zope behind Apache recommend
starting with sfm's SiteAccess enhanced Virtual Host Monster product:
http://www.zope.org/Members/sfm/SiteAccessEnhanced/view

Reportedly last updated 2001-08-19, is SAE really so mature that it has
not subsequently needed updates or merited a merge into Zope's own VHM?

I need to map the incoming URL http://(*.)foo.com/new/* to a Plone
instance at http://localhost:8080/foo/*; , and later change the
inbound mapping to http://(*.)foo.com/* after customer acceptance.

I'm guessing that this is the most vanilla virtual hosting requirement
possible, and I want to use the simplest configuration to accomplish it.
If the old SEH 2.1.0 is the recommended tool with Zope-2.8.1, I'm sure the
existing docs will be enough to figure it out. Thanks.

 The only thing I can think of which matches your symptoms is this. Is it
 possible you have misconfigured this new Zope 2.8 instance, and it's

I feel like a guy who brought the lawn mower in for repair, and they tell
you 'its got no gas in it'. That was it of course, thanks for the catch.

I normally diff-merge my zope.conf with each successive version, to pick
up any new directives, comments, etc. I guess I forgot the zodb section at
the tail end when moving from 2.7 to 2.8.

It might be helpful to have the list of mounted databases (and thus ZEO
vs. FS distinction) in the control panel summary, that seems like useful
configuration summary information.

Thanks again, and sorry to take up list traffic with a simple
configuration mistake.

[Zope] zopectl debug, 2.8.0 local zeo, Data.fs.lock file locking error

[Jeff Kowalczyk]

I am trying to use 'zopectl debug' for the first time with zope-2.8.0,
local ZEO setup. It worked fine with zope-2.7.x and earlier. I am now
getting a file locking error on Data.fs.lock, which stops the debug
initialization at that point. The problem occurs whether I run zopectl as
root or as the effective user ('zope')

Can anyone familiar with local ZEO debugging on linux spot what might be
the cause of the file locking error? Thanks.

I get a little fuzzy on when the changeover from user root to user zope
happens, but this is the confusing point, and why I originally excerpted

read-write on the Data.fs.lock file?

Should I add user root to group zope, or would that defeat the security
purpose of the effective-user? Or can you recommend the correct chmod
setting for this setup, I don't want to 755 the thing into wide-open
access without knowing what I'm doing. Thanks.

This is a local ReiserFS partition. The zope and zeo are on the local

I just checked, and it is not the 'zopectl debug' that fails, it is the
second connection to the running zeo; if you run zopectl debug first, that

I just did a chmod 666 Data.fs.lock

And to my surprise, that doesn't change the second zeo connection problem,

[Zope-dev] Best practice for Zope-private copy of Python 2.1 on Linux?

[Jeff Kowalczyk]

With the RH7.3 release today, the default Python2 installation is that
much more likely to be Python 2.2 (it's the base package in RH7.3),
instead of Python 2.1.

Rather than ask the FAQ of why and what parts of Zope can't handle
Python 2.2, I'll ask if there is, or suggest if there isn't, a shift due
in the installation procedures on Linux to optionally use a private copy
of Python 2.1, much like the Windows version of Zope does. That version
allows me to use Python 2.2 without any interference. I'd prefer that
the file layout matched WinZope as closely as possible. In this case,
I'm willing to give up some disk space to have a sandbox that Zope can
run in with its configuration uninterrupted.

FWIW, I'd like to see an expanded tarball of Zope available that builds
the whole thing, including its own Python and the most common
c-extensions, in a unified makefile. Maybe that would get the
possibility of RPM releases back on track, too.

Can anyone suggest a best practice to get Zope 2.5.1 on Linux running
with a private Python2.1, keeping the new Python releases separate from
the one Zope will use?

[Zope-dev] Medusa 0.5.1 maint release, planned for inclusion in Zope?

[Jeff Kowalczyk]

From the Daily-URL: Andrew Kuchling: Medusa 0.5.1 released: Medusa is a
framework for writing asynchronous socket-based servers. It was
originally written by Sam Rushing. However, no new releases have been
made in about a year. I've therefore taken the original Medusa package,
and reformatted the code, removed various outdated modules, ran
PyChecker over it, wrote a Distutils script, and made a new maintenance
release of Medusa.

[Jeff] Will this version of the Medusa code be making its way into the
Zserver core for the 2.5.x maintenance releases, or the 2.6 timeframe?

Re: [Zope-dev] Medusa 0.5.1 maint release, planned for inclusion in Zope?

[Jeff Kowalczyk]

[Chris] Does Zope 3 use Medusa at all?

[Stephan] No. Shane rewrote all of the HTTP Server and I am writing
right now the FTP 
server (which copies some of the Medusa code, but much is cleaned). We
added interfaces and made it more component-based.

[Jeff] That's good news about an interface refactoring, it was a little
confusing researching the present customized version. My interest in
(the Medusa revision) was to keep alive the idea of setting up hooks for
developers to build support for other protocols (IMAP, NNTP, Jabber,
SMTP, SMS etc.) in a standard, configurable way in Zope3. Will your
rewritten components form on a general-purpose server framework like
Medusa? Ideally, the support would be as easily added as other 3rd party
Zope3 product/components, inheriting from the base components you guys
are writing now.

The topic kind of thudded when I brought it up last week, but I think it
is important to keep an open mind about it while Zope3 is still brewing.
Interfaces to external mail and other servers is only part of it, since
that makes workflow programming on the messages much less direct, and
reduces the cross-platform flexibility of Zope deployments, where most
extensibility is done in Python.

Lots of *small* businesses need what MS Exchange offers, but can't
afford it nor safely maintain its staggering complexity. As these python
protocol implmentations crop up, I'd like to see Zope3 offer those
writers a mature, cross-platform back-end to store their messages in, if
they are willing to implement a few well-defined interfaces.

[Zope-dev] ZMI: IE6 TextArea width bug: fix on tap for 2.6?

[Jeff Kowalczyk]

I was wondering if there was any consensus on how best to fix or
compensate for the unfortunate behaviour of IE6 with regards to the
width calculation of textarea boxes. For anyone who hasn't seen it, the
full-width texareas that are everywhere in the ZMI suddenly started
pushing the width out in IE6, causing the horizontal scrollbar to become
active, and generally making ZMI editing life miserable.

Would it be possible to include in 2.6 (or 2.5.1, even better) a user
preference, sitewide configuration setting, or other means of
suppressing a few pixels/percent of that default width? I'm loathe to
apply a massive search-replace to put 95% in my local ZMI source, and
IE6 must be a common enough platform for Zope users to warrant a
workaround. I wouldn't hold my breath that MS would fix IE or anything
sensible like that.

It would be a shame to slow the whole thing down with browser detection
logic for this one bug, unless that opened up the door for some of the
Javascript/DHTML editors as a per-user preference for editing certain
metatypes.

[Zope-dev] Impact of additional protocols handled by Zope?

[Jeff Kowalczyk]

I'm curious what the impact on overall performance would be if products
eventually came into existence that extended Zope to directly handle
additional protocols and their data requirements, primarily intended for
low-volume workgroup kind of traffic.

Jabber, IMAP and LDAP are the ones that come to mind immediately, since
you'd be that much closer to having Zope fulfill a role that MS Exchange
really doesn't; inexpensive, easily maintained groupware for small
organizations that need custom workflow app development.

Is it practical to consider that Zope might extend into other protocols
this way, and can it be done with modular products, or does integration
require deep Zope modifications (beyond adding a few lines to Z2.py?)

Just a hypothetical, I guess. FWIW, it would be really cool to see a
general, host-a-protocol-here hook for plugin products as Zope3 takes
shape, configuration in the ZMI if the product writer goes that far.
Something that would define a standard interface for Zope3 events to
respond to signals the protocol handler might generate, and vice-versa.

Re: [Zope-dev] Impact of additional protocols handled by Zope?

[Jeff Kowalczyk]

[Eron] Yeah, this is something I'd be very interested in knowing, too.
In fact, this particular ability could make or break a community project
I'm going to be developing with Zope in the near future. Do you mean
like the pluggable access that ZServer provides? I imagine there would
also have to be some kind of pass-through backend storage to the actual
service layer (like IMAP, for instance). This is definitely something
I've been thinking about. [Eron] Getting my gears turning, Eron

My thinking is that the protocol(s) that people might develop would be
action-interfaces to Zope objects and methods. The canon example is
IMAP, I guess. Someone might finish up something like
http://www.zope.org/Members/michel/MyWiki/IMAPServer , and
access/create/control Zope objects persisted directly in ZODB, using
variations on the classes people already have for the various Zope Email
Clients. Add Binari's IMAP Plug-In to the ubiquitous Outlook, and you've
got a poor-man's Exchange Server*. To get public folder workflow, you'd
need to use CMF (or Openflow), but that should change by the time Zope3
takes shape, workflow will apparently be native to Zope. (Can't wait)

Jabber (or IRC, etc.) would be a slightly different use case.
Jabber.py's maturation might mean that you could have a small number of
users conferences authenticated against Zope's users. The users would
use normal Jabber clients, but this should make web-chat interfaces very
doable, too. A Zope Jabber protocol server might implement active
conversations in session memory, and persist to Zope objects in response
to a Jabber command. Jabber's logging idioms produce XML documents in
the jabber.org implementation, ours would be Zope objects or whatever
was needed by the developer. The back-end would be all Zope's turf.

As for LDAP, existing LDAP products connect to external LDAP servers.
But wouldn't it be useful if Zope's user database, and other folderish
resources could be exposed as LDAP, with Zope as the server? A Dynamic
DNS protocol handler could pump authenticated user's IP info into the
LDAP tree, and so on.

I'm probably getting ahead of myself here, its not like python
implementations of these sophisticated protocols grow on trees. But they
do seem to get started in the python community from time to time, and if
Zope offered an easy way to hook a budding protocol implementation in to
a mature application server, there might be a lot of can-do attitude to
getting them beyond alpha stage. The key would be if the developer could
add/delete/configure protocol products as easily as content products. As
I said, It wouldn't take much for Zope to be a great Exchange drop-in
replacement in your typical small business. It wouldn't really matter
that much if python implementations of these protocols didn't have the
scalability of their C-based brethren, lots of small Zopes doing
big-server work would be a nice thing to develop against.

* Better than Exchange, IMHO, because you'd have to be nuts to deploy
Exchange or Small Business Manager in a real small business with no
on-site IS Manager to handle backups or Active Directory admin duties.

Re: [Zope-dev] ZMI textareas on Windows IE6 are '100%+' wide, cause scrolling inconvenience

[Jeff Kowalczyk]

[Jeff] You're right, I wonder if this is a documented change in IE6, or
a bug they plan to fix? I can't imagine in what universe that including
the scrollbar-obscured area in the 100% width makes sense. I'd hate to
see all browsers' HTML get munged to cover this bug up. But given the
pervasiveness of IE6, maybe the ZMI should make some accomodation for a
preference that 9x%'s the width of the right frame.


[Joachim] I think the problem is more severe. IE 6 has obviously changed
behaviour compared to IE 5.5. I'd call it a bug. It now always
calculates 100% with the right-hand bar's width INCLUDED, so there are
other side-effects than the one you are describing, like the last tab on
the right being partially covered by the scroll bar.

So if we change the HTML, it should limit the width of the WHOLE
right-hand frame, not just the textarea's width ...

Unfortunately this will only work automatically with some browser
detection ...

[Zope-dev] ZMI textareas on Windows IE6 are '100%+' wide, cause scrolling inconvenience

[Jeff Kowalczyk]

On my Zope 2.5.0 running on WindowsXP/IE6, the ZMI's textarea boxes, for
things like editing PageTemplates, becomes too wide for the frame when
the vertical scrollbar is required, causing an inconvenient
side-scrolling behavior. The frame must be scrolled sideways to view the
text areas's scrollbars, which then obsures the far left of the
textarea.

This is the code in question (for a PT edit page, there are many others)

Would it not help to make the textarea and div width 90% or so to
account for the potential width of the side-scroll bar on the right-hand
ZMI frame? Or even better, this could become a preference setting, since
some users will have very narrow scrollbars or extreme vertical
resolutions. After all, there is a cols/rows insertion right next to it,
perhaps a new preference setting is easy enough to add...

[Zope-dev] RE: Experiments with ORMapping

[Jeff Kowalczyk]

 I was thinking there would be a default table where everything gets 
 stored by default.  A programmer then tells the ORMapping about 
 specific classes and how to store them.

I wouldn't think it would be practical to use unless the ORMapping
managed the tables by examining the class signature as metadata. ADO.NET
has this in reverse, the tools can define classes that mirror a SQL
recordset. Similarly, references to other objects would need to be
supported with joins.

BTW, I was going to mention this article
http://www.vbpj.com/upload/free/features/vbpj/2001/07jul01/sqlpro0107/re
in0107/rein0107p.asp
As a 'rah-rah zope' example of RDBMS complexity Zope/ZODB spares us, but
now it brings up something the ORMapping layer would have to do (perhaps
with more savvy) to support mixed folder hierarchy among class
instances.
