Re: [Zope-dev] Buildout - including per-user site-packages dir.
Hi again,
I got the same error with zpasswd, so had to repeat the process with that
section of buildout.cfg, too... Thought I'd explain the specifics, while I
remember...
On Tue, 25 Jun 2013 19:44:48 +0100, Alex Leach albl...@york.ac.uk wrote:
The buildout configuration that seemed to fix this, was to add 'recipe =
zc.recipe.egg:scripts' to my package's section, and
'allowed-eggs-from-site-packages = peak' to the `[buildout]` section.
I found the documentation on these options, unsurprisingly on the
zc.recipe.egg and z3c.recipe.scripts PyPi pages.
('allowed-eggs-from-site-packages = peak' is not what I thought it was
yesterday, so please ignore it).
I don't think I had edited the zpasswd section before yesterday, so it
should have been exactly as it was, when initially generated by
`grokproject`:
[zpasswd]
recipe = z3c.recipe.scripts
eggs =
my_package
zope.password
entry-points =
zpasswd=zope.password.zpasswd:main
I'm not entirely sure why zpasswd has to import every module in
my_package, but it seems to try. So the above configuration causes zpasswd
to fail, when a required package is installed into the user's
site-packages folder.
It's worth mentioning, if you're unfamiliar with the user's site-packages
folder, that it is supported by every Python build system I've tried:
distutils, distutils2, numpy.distutils and setuptools. The following
setup.py command, which works on all of these build systems, installs a
package into the user's site-packages folder:-
$ python setup.py install --user
With the documentation in front of my, I added these options to zpasswd,
but none of these add the user's site-packages folder to the search path:-
include-site-packages = true
exec-sitecustomize = true
relative-paths = true
extra-paths = ${buildout:directory}/eggs
interpreter = python-console
However, changing the recipe does:
recipe = zc.recipe.egg:script
So, my conclusion is that it's a feature / limitation / regression in
z3c.recipe.scripts. I only say regression, because on the
z3c.recipe.scripts PyPi page, I've just read:-
The script recipe installs eggs into a buildout eggs directory, exactly
like zc.recipe.egg [...].
Well, not exactly... This is one difference. I'll continue to use
zc.recipe.egg, as that works as desired in this situation, but it feels
like I'm downgrading, which is never fun...
Hope that clarifies things, anyway.
Kind regards,
Alex

I think changing the package recipe in buildout.cfg fixed it, but it could have been something I did in configure.zcml.in, as I've been separating some things out into other namespace packages recently, and that was one file that needed tweaking. The buildout configuration that seemed to fix this, was to add 'recipe = zc.recipe.egg:scripts' to my package's section, and 'allowed-eggs-from-site-packages = peak' to the `[buildout]` section. That second one also helped resolve some dependency / conflict issues I was having with PasteScript - I also have it installed system-wide for some reason - and seems to reduce the need for duplicating some system packages.

Re: [Zope-dev] Porting Zope to Python 3 Update
On 2013-03-02 00:34:04 +, Stephan Richter said: Hi everyone, as the week ends, I thought I might give a brief update on the Python 3 porting effort. According to the Unofficial Zope on Python 3 status page[1], about 110 packages are ported to Python 3.3. Hanno and I worked this week on updating the ZTK configuration files and I am happy to announce that the ZTK passes all tests on Python 3.3! So once the ZODB is ported, we can start on finalizing all releases, which would pave the way for a ZTK 2.0 release. Marius has made great efforts on finishing the port of ZODB. All the tests pass now on the py3 branch for Python 2.6, 2.7 and 3.3. He has also removed all resource warnings (he started at 400+). The final task will be to integrate zodbpickle. zodbpickle needs some changes to properly enable the noload() method. Luckily this work will entail rewriting the dump/load of persistent ids to be more efficient and compatible with cPickle 2.7 pickles. (We are working hard on making Python 2 pickles load on Python 3!) On Wednesday, I was able to run a first Zope 3 (or should I say Bluebream?) app on Python 3.3. Thanks to Andrey and Albertas for porting some of the complex application packages. The sample application can be found in ``zope.paste``[2]. Note the short ZCML[3] and Paster[4] files. Thanks goes to everyone who helped breaking unnecessary and circular dependencies to make this work so well! In the process of all of the above, we have also started moving all packages that we are ported to Python 3 over to GitHub. I have also ported the core packages for Zope 2/4 and Grok already. So what's next? I am in the process of trying to port a rather large demo application[5] to Python 3. We are about 20 packages (that we control) away from that goal. Andrey is currently working on porting zope.testbrowser to Python 3 by changing its internal implementation from mechanize to WebTest (since it is too hard to deal with mechanize). Also, we will have a serious look at ZEO. I hope I got some of you interested in thinking about porting applications to Python 3. Yes! Very exciting update, thank you. And speaking of old libraries supporting Python 3, in case anyone needs PIL with their Python 3 Zope apps, I could use some help testing the soon-to-be-released Pillow 2.0 (PIL fork) with Python 3 support: git://github.com/python-imaging/Pillow.git.

Why is it the wrong tool for the job? I read up a bit on asyncore, and see it's supposedly a single threaded server. Is that part of the problem? The way I see it, zope's got its own web server and framework that handles HTTP requests; WebSockets initially connect over HTTP, before upgrading to a WebSocket connection. If the 'upgrade' request was recognised by zope, then couldn't it just forward the connection on to any WebSocket server? It wouldn't even need to do the handshake, but a compatible proxy would no doubt need to be implemented. There are dozens of better solutions for Python like http://autobahn.ws/ The dependencies of all other Python-based WebSocket implementations all require a completely different application stack. Twisted, which autobahn uses, looks very powerful for low-level networking and the such, but it's a beast and I've never used it before, in favour of making templated web apps with grok.. Also, wouldn't the front-end socket of autobahn conflict with any other running HTTP server? Sure, I could set it up on an alternative port, and use a front-end webserver to proxy requests appropriately, based on URL paths and patterns, like I do now with grok and Apache. But that adds another two complications, when it comes to initially setting up the server. Installation instructions for potential users would become even more off-putting than they already are. The zope server already has a good system for URL parsing and dispatching. Would zope.proxy be any good at proxying WebSocket requests based on the URL? Don't try to misuse a framework for a purpose that it has not been invented for. WebSockets hadn't been invented back then, but HTTP was always meant to be bidirectional. Get with the times :b (jk) So, I think I understand that zope might not be great for managing simultaneous bidirectional traffic, which is basically a requirement of a WebSocket server. Could it not be a good proxy either?

Hi, Thanks for the reply. On Tuesday 27 Nov 2012 09:04:11 Wolfgang Schnerring wrote: I'm not too familiar with WebSocket internals, but one thing that stuck with me is that you'll need to keep *lots* of open connections, which is only feasible with an eventloop-based server (which zope.server, for one, isn't). Oh. That's an interesting point... I'm no expert either, but have seen them mentioned a lot recently, and started looking through the RFC the other day. Apart from that, I'm not sure what features remain, and where a proper home in the ZTK world would be. As I use grok, I had a little dig in grok's dependencies, and thought that zope.publisher.ws could be an appropriate home. I branched zope.publisher from Launchpad / bazaar and started copying stuff over from zope.publisher. [interfaces.]http. I thought that might be a nice way to start things going. At our company we've scheduled a project to integrate WebSockets into a large Zope3-based application for early next year, so we'll definitely will be doing *something* in that space -- we just don't know what, yet. ;) Same here really. I just thought I'd try and start playing with WebSockets, as they sound quite fun, persistent and fast. What functionality did you have in mind that the ZTK might grow? Good question. The main feature I thought ZTK would benefit from, is managing the handshake, and forwarding the connection to the relevant socket. I see no reason why the server endpoint needs to be a Zope application (could be a completely separate application, written in C++ for example), but Zope would still need to recognise the URL prefix (ws:// or wss://) and to connect the endpoints. In the grok world, I thought a conf file might be an appropriate way of configuring the server socket port numbers and whether to start a listener on (or forwarder for) that port. As the initial handshake is done over HTTP, Zope would mainly need a way of recognising the WebSocket request and to delegate it appropriately. In terms of public methods for a developer, this would be optional on whether Zope / grok manages the endpoint or not. If it did have control of the server- side WebSocket (e.g. localhost:), it would need a write method and methods for parsing WebSocket frames for Content-Length etc (see Section 5.2 of RFC6455), and to return only the payload data. I haven't any experience with bit-wise operations, so could do with some help with parsing that first byte of the frame. Finally, I think testing will be a bit of b*tch, as Zope would also need a WebSocket client to perform the testing... Hope that helps. Cheers, Alex Wolfgang -- Alex Leach BSc. MRes.

On Tuesday 27 Nov 2012 07:04:43 Jim Fulton wrote: Actually, it is. zope.server is based on asyncore. Having said that, my impression is that web sockets is largely (or completely) orthogonal to WSGI and the HTTP-based publishing infrastructure. From the RFC: The WebSocket Protocol attempts to address the goals of existing bidirectional HTTP technologies in the context of the existing HTTP infrastructure; as such, it is designed to work over HTTP ports 80 and 443 as well as to support HTTP proxies and intermediaries, even if this implies some complexity specific to the current environment. However, the design does not limit WebSocket to HTTP, and future implementations could use a simpler handshake over a dedicated port without reinventing the entire protocol. This last point is important because the traffic patterns of interactive messaging do not closely match standard HTTP traffic and can induce unusual loads on some components. ZTK is only relevant to the extent that it's a bag of useful libraries maintained by the Zope community. It is a bag of useful libraries :) Is there anything that would ease the development of a WebSockets server, though?

[Zope-dev] WebSockets API
Hi, I was wondering if anyone has implemented a WebSockets server API using the zope toolkit? I've just submitted a blueprint on Launchpad (https://blueprints.launchpad.net/zopetoolkit-project/+spec/websockets-api), but thought it might be quicker and easier to discuss how one could do this here. In theory (and practice, e.g. http://popdevelop.com/2010/03/a-minimal-python- websocket-server/), only a very small amount of code is needed to deploy a secure WebSockets server. I'd be happy to have a go at doing this myself, but thought it would be better to implement upstream, within one of the zope packages. I've been developing with grok, so I'm not too familiar with the internals of zope publishing, though. Please could someone point me in the right direction, with regards to modules and base classes responsible for parsing requests and performing handshakes?

[Zope-dev] zc.buildout semi-resolution
Hi, FWIW I spoke with Jim on #buildout this a.m. and he decided to revert my commit because people need it. I.e. Some folks rely on trunk/bootstrap existing for their builds. While I don't necessarily agree that's a good idea, the argument because people need it makes 1000x more sense to me than Please revert with no explanation. Or with a legal explanation I don't understand. I apologize to Jens and Tres if I was stubborn about this, but I did and still do feel strongly the commit I made was reasonable, and not reverting it until we could better understand the circumstances was reasonable too. To clear up any remaining confusion: - In the Plone community, it is quite common to make this type of change to indicate active development takes place somewhere else. We leave tags (and branches) in place in case people need them. I did not remove, or move the zc.buildout project, nor did I intend to disrupt development in any way. I simply wanted to leave a message on behalf of the work Jim and Domen were doing. - Personally, I use an extension called buildout.bootstrap to always download the latest bootstrap.py file. Removing trunk broke my builds, at which point I cut a new release of buildout.bootstrap containing the new URL: - http://pypi.python.org/pypi/buildout.bootstrap/1.4.2 I hope the discussion on GitHub and Bitbucket, and other vendor services continues.

You can't just take core software pieces from Zope Foundation-hosted repositories and move them somewhere else. Thanks! I think you are confused. I would suggest you ask Jim Fulton about it, as he moved Buildout to GitHub months ago. Both 1.6.x and 2.x are under active development there. Further, I committed the *message* about the move and I removed trunk to avoid confusion, I didn't personally move anything (Jim moved 2.x and Domen Kožar moved trunk to the 1.6.x branch).

[Zope-dev] zope.formlib - Overriding default widget attributes
Dear Zope Devs, I'm trying to remove a couple of default attributes from the rendered version of the schema.Text widget, namely cols and rows. I tried overriding the widgets attributes with None, which didn't work. I then found in renderTag, in zope.formlib-4.0.6-py2.7.egg/zope/formlib/widget.py:603 that if a value of one of the keyword arguments (**kw) is set to None, then the value is set to the key, and a deprecation warning is issued. In my case, this therefore produces HTML with attributes like cols=cols, and rows=rows. I don't like that at all, as all my styles are defined in CSS and jQuery, and this overrides them! So, please can this be replaced with a `continue` flow statement instead?? Suggested patch:- zope.formlib-4.0.6-py2.7.egg/formlib diff widget.py widget.py.orig 600c600,602 for key, value in sorted(kw.items()): --- items = kw.items() items.sort() for key, value in items: 602c604,611 continue --- warnings.warn( None was passed for attribute %r. Passing None as attribute values to renderTag is deprecated. Passing None as an attribute value will be disallowed starting in Zope 3.3. % key, DeprecationWarning, stacklevel=2) value = key In fact, I'd also get rid of the `if kw:` line, as it seems unnecessary...

There are plenty of people that still think Zope software is cool, and plenty of skilled developers on github that could potentially help move it forward. This discussion seems to unnecessarily combine at least two distinct issues: - what RCS software to use - where to host it It may be easier if we disentangled them. Traditionally it was easier, but now-a-days with github and bitbucket they are harder to disentangle. Speaking purely as a developer, I'm leaning to Git when it comes to the RCS software decision between Subversion and Git. But I can use both equally well. Where it is hosted, well, purely as a developer it doesn't matter to me, unless I need to give up too much personal data to get access. From the perspective as a Zope Foundation member the RCS software decision is a technical detail that doesn't matter much. I'm more concerned with the where question, though. The Zope Foundation is tasked with safeguarding the software released under the Zope Foundation umbrella, and it is tasked with enforcing the contributor agreements everyone signed. Commits can only be made by signed contributors, and contributors are specifically disallowed to take outside code they don't own and commit it to the repository. We already have the technical infrastructure in place for most of this, such as ZF-controlled logins on svn.zope.org, access only via SSH key, etc. Our current where can be fully trusted, so to speak, and the people tasked with maintaining this infrastructure are known, accountable, and part of the foundation. My third role is secretary of the Zope Foundation Board of Directors and in that role I collect and maintain contributor applications and the (private) data associated with it. I can vouch that our current means of storing this data is reasonably secure. I can't make that assertion if the data is stored somewhere out of Zope Foundation control. My last role is admin for the ZF infrastructure and servers. In that role I would be involved in executing any changes in repository hosting. If only the RCS software changes that's a chunk of work, but doable. Git service can be added to the ZF infrastructure and packages can be migrated into Git repositories, probably on a as-needed basis. Most of the current authentication and safety infrastructure could stay in place. On balance and taking all my roles into account, sticking with SVN and the current hosting is the most attractive option. Moving to Git in the current hosting environment is doable, it means work, but I feel I've done my job keeping the software, access to it, and contributor data as secure as possible. Any option that involves moving to a different host altogether not only makes me feel I haven't done my job, it may also throw up legal questions. Fair enough, all of this sounds reasonable. My only point was that it should be someone's role in the ZF to take a look around at the available options in today's software development ecosystem. If github.com is attractive to you, great. If it's not and you are happy with the status quo, also fine. But like anything else, there are pros and cons associated with either approach. E.g. Plone's move to github has been a challenge for a lot of people, and we continue to struggle with it everyday; but I know it was the right move for the software and the project so I feel good about what we are doing.

Traditionally it was easier, but now-a-days with github and bitbucket they are harder to disentangle. It is entangled, but it is important to notice that they are separate concerns. I do think the big issue is where to host it. Yes, fine, people have opinions on git vs svn vs hg, etc. But that boils down to 25% technical arguments, 25% what you are used to 25% what everyone else uses and then 30% religion to make sure the bucket overflows. But where to host it is a tricky issue. Ownership and control is one big argument for having our own servers. Githubs forking/merging process a big argument for going to github. Should you then decide that github is the place to host it, well, then git is the software to use. Actually, they introduced improved Subversion client support late last year: - https://github.com/blog/966-improved-subversion-client-support (they've supported import-from-svn and limited svn client support for longer) To be honest I see little point in just setting up our own git repository. Yeah, maybe git is better from some technical standpoints, but it's also harder to use, and the question then becomes just religion. What we would like to do, of course, is to have a self-hosted github. :-) (And that exists.

Zope 4 only exists as a transitional path for Zope 2 based applications and experience has shown that Zope 2 releases not used in any Plone release do not receive the same level of ongoing maintenance. I would actually argue that Zope4 have no real release cycle at all: instead, the individual pieces which make up Zope should have their own cycles, with perhaps a ZTK-like tracking set that Plone and others use as platform targets. -1 - we'll need something to amalgamate this into a release and we'll need a way to manage and number those releases. That is what the ZTK does now: it is an amalgamation of releases of separately-managed packages, which periodically gets a versioned release itself, mapped as an index or a 'versions.cfg' file. We want to encourage all features to be developed on separate feature branches so we can maintain a stable trunk. Before these feature branches are merged they should be posted to the mailing list for review. This process will necessitate a lot of merging, so I want to propose that we move to Git for development (something we found very helpful at our recent San Francisco Zope 4 sprint.) Note that this question is *not* suitable for loudest voice on zope-dev wins ressolution. The software belongs to the Zope Foundation, which will make any such decision. The work done on github by the Zope4 sprinters in SF should be seen as scratchpads for work which will be migrated back into the canonical repository for each project. A couple of points for consideration: - - bzr and hg are pretty much isomorphic to git WRT this kind of practice. Both have claims on our community which Git does not (hg because it is the tool of choice for Python, bzr because we already use Launchpad). Note that I use Git daily, and the others somewhat less frequently: I'm not speaking from ignorance here. - - Merging feature branches in SVN is not *that* difficult, typically: I've done scores of such merges myself with almost no pain (and the really painful ones would have been pretty much as bad with git / bzr / hg). In the Plone community, we held a poll. GitHub won hands-down. The second choice was staying with self-hosted SVN Again, this is a choice to be made by the foundation: any polling will be done by the members of the foundation (this might be the biggest non-election item on the agenda for the next annual meeting). GitHub is a big leap forward in software project support. It's also rapidly becoming a de-facto place for many people to look for software. We win if the people we want to encourage to fix bugs or contribute features have a low barrier to entry. github's biggest wins, compared to self-hosted git or SVN, are for casual contributors submitting easy-to-merge patches. Given that the new-old Zope is explicitly avoiding marketing itself to new developers, I don't find that win all that convincing: there is no point in having machinery for pull requests from folks who could push the changes themselves. Note that this also includes Plone developers working on Plone at this stage, since Plone has now moved to GitHub. So, my personal vote would be for Zope to use GitHub (with a backup mirror), allowing me to have a more integrated toolchain. Personally, I find GitHub substantially better than BitBucket, especially for collaboration, and Launchpad nearly unusable. I'd encourage you to look at usage and growth statistics for the three main hosting/collaboration services. I don't think what everybody else is doing is all that relevant: this isn't a popularity contest, and Zope has permanently lost its standing with the shiny-obsessed cool kids. We need to choose on the basis of enabling the currently active developers to work together productively. -1, I feel it's at least somewhat relevant for the Zope community to occasionally examine its environment, if for no other reason than to see how it can benefit from what others are doing. I was just thinking the other day how I'd really like to do some zc.buildout dev/maintenance (motivated in part by Ross Patterson's recent work) and immediately thought I hope they move everything to github. And I'm delighted to see that this discussion has actually begun. Bottom line: Zope stands to benefit greatly if the current active developers keep an open mind about how/where/when development of Zope software should occur. There are plenty of people that still think Zope software is cool, and plenty of skilled developers on github that could potentially help move it forward.

Hi Alex,
With the help of Jim, who produced a tarball containing the spidered content
of old.zope.org, the site has been converted to a static site. There will
inevitably be issues here and there. I'll take a look to see if I can find
the original files from the old app server.
Thanks Jens, I know I occasionally need to build old Plone sites, as far
back as 2.1 but also sometimes 2.5.x and 3.{0,1,2}.x all of which use
the old tarballs ranging from Zope 2.8 - 2.11 (I think). Building these
sites will require at least the final from each series to continue
working. Ultimately, I'd love to be able to access all the old tarballs
e.g. similar to:
- http://dist.plone.org/archive/
But I realize this may require some significant bit of effort!
Thanks again for the effort,

[Zope-dev] What happens when a KGS changes?
Folks, How do we handle a situation like the one I'm about to describe w/4.1a3 and c.xdv?

[Zope-dev] GenericSetup sans (Python) package?
Hi all, I floated an idea in a blog entry recently (here: http://blog.aclark.net/2011/01/19/new-website-for-2011/#todo) and I'm wondering if it's an attainable goal, or just a pipe dream: --- I want to add GenericSetup (GS) profiles outside Python packages (i.e. in the buildout via ZCML). Currently GenericSetup expects to be passed a context which is (I think) the old-style Zope 2 product object in the ZODB. But I can’t think of a reason why GS couldn’t be made to work sans that requirement (I’m just speculating though, I haven’t looked at the code yet). --- Should I bother checking out the Products.GenericSetup source code to see if something like this is possible? I really, really, really, don't want to create a Python package just so I can save a couple settings in my (Plone) site.

Then you get ZCA a component architecture for Python. It has nothing to do with Web whatsoever. E.g. zope.component and one or two others? 3. Then we have ZTK. A toolkit for building web frameworks. This is where you lose me. What's an example of a ZTK package? I can't think of one off the top of my head… ah ok, I just found this: - http://docs.zope.org/zopetoolkit/releases/packages-trunk.html So ZTK is ZCA plus the bits that make it suitable for building web frameworks. And is it fair to say I can just build any web app with the ZTK? I don't need any of the frameworks that are already built, I'm free to reinvent the wheel if I choose too. 4. On top of that we have Zope 2, BlueBream and Grok. I.e. The Frameworks™ 5. There is also BFG, which doesn't include/build on the ZTK (as the others do). Right, it's loosely coupled with the ZCA, but you can throw that out too, if you like? It's pretty clear to me.

And when it comes to separating the frameworks it obviously becomes more complex. So we need to explain this, what the different framworks are good at in a clear way. I see it like this, but I could be wrong: * Zope 2 is the granddaddy of the frameworks. It's not really built on top of ZTK, but includes it. You basically only use Zope 2 if you are using some sort of software that builds on it, like Plone, Silva, or something custom. To build on my earlier car analogy: Zope 2 is an old pickup truck. You can get it to do anything. You can drop it from the top of a building and it will run. When it breaks you whack it with a hammer until it's not broken anymore. But it's diesel engine kinda stinks. * BlueBream used to be called Zope 3 and is a component based enterprise kick-ass do everything framework. Everything is configurable and it doesn't just include batteries, but a whole power plant. Which admittedly can be tricky to run. BlueBream is a train. Fast, big and pulls heavy loads, and good for the environment. If that's what you need, you know it. * Grok is an easier to use (and at least in the future also smaller/lighter) framework than BlueBream, while retaining the flexibility. Instead of having to configure everything, you have sensible defaults. Less typing, and it doesn't feel like J2EE. Inspired by frameworks like Django and Turbogears, you get the nice Python framework feeling with the power of ZTK behind you. Grok is a an hybrid minibus. Easy to drive, infinitely reconfigurable just by switching the seats around. * BFG is a minimalistic web framework built on Zope ideas and experiences, but as a part of it's minimalistic nature does not include *anything* of the ZTK, it just builds on the ZCA. But you can use the ZTK, if you want to, you are just not required to do so. It's for the purist, for the guy who wants to build his own streamlined speedmonster. BFG is a frame with four wheels and an big engine. The rest is up to you.

So - if even we have problems understanding, how would things look like for complete newbies? +1 FWIW I think of the ZCA as: The abstract concepts that define modern Zope programming e.g. component, adapter, interface, view, utility, etc. which is most often compared and contrasted with old style Zope 2 programming, e.g. acquisition, traversal, etc. As such, I make a pretty big distinction between the ZCA and the rest, e.g. Zope 2, the ZTK, BlueBream, Grok, BFG, Plone et al. The former is a concept, the latter are implementations of that concept, to varying degrees. I don't know or particularly care what packages make up the particular products/frameworks/whatever. (In fact, I find the whole ZTK concept a bit confusing. If the ZTK is just a collection of packages why argue over which packages? Why not declare every damn Zope-ish package part of the ZTK? That would include Chris's BFG, which implements CA concepts. So why not? Who cares? :-) We certainly have not reached the goal of helping newcomers understand the Zope ecosystem in any other way to date, IMO.) With that in mind, I can view the ecosystem very much like: http://wiki.zope.org/bluebream/BlueBreamName. But I might draw it like this: # Zope Ecosystem # == # #.--. #|ZCA (abstract concepts) | #| .-. | #| |ZTK (a bunch of Zope-ish packages that may or may not || #| | be useful to you)|| #| | - ------- || #| | | || | | | | ||| #| | |BlueBream|| Grok | | BFG | | Zope2 ||| #| | | || | | | | ||| #| | - ------- || #| | || #| | -- || #| | | repoze.zope2*| || #| | -- || #| `-` | #| | #`--` So I guess the point is, you can draw BFG with a line pointing directly to the ZCA and explicitly avoiding the ZTK, but I'm not buying it, personally ;-) Why? Because I consider BFG and whatever packages it consists of to be part of the general set of tools I may use as a Python/Zope loving web developer. And what's a good name for a set of tools that I may use to build something? Wait for it… a toolkit! Alex P.S. *Merge me back to Zope 2 Hanno, please!

Here is my point of view, as 'site manager'. We are creating small sites for end-users, and we try to use Zope in many cases, recommending this platform to end users. Many customers refuse to use Zope because of one simple reason: they look at http://www.zope.org web site, and then get back to us asking us how we could recommend this product. In my opinion the most important fixes to web site are: - Web site (zope.org) is very slow, and contains outdated documentation, links. Not well organized. Does not look professional way.I have no idea why zope.org site is slow and dying, but if it is because hardware or any kind of misconfiguration problem it must be fixed a.s.a.p. Just tried to open home page of http://www.zope.org - my Opera shows 1 min 11 sec to load. (compare, www.php.org loads in 5 seconds). This makes our customers to make false decision that Zope is a way too slow. Most of customers refused to work with Zope because they tell: all sites we looked at seems to be really slow. - Look at Zope powered sites:http://www.zope.org/Resources/ZopePowered/. At first 4 sites are not enought to convience any commercial customer. Even total of 11 links found on the page is not enought. I suggest to have submit a site form on this page so end users will submit their sites URLs and the list will be growing. Inactive sites should be removed after some time. - I do not understand the link to Zope CMF which leads me to http://cmf.zope.org/ and where I read ATTENTION! ... Please don't add new content here What this site is about, if it should not be used. Is Zope CMF dead? I see it is not, but this link makes me confused. - Zope HowTos contain all documents made in 1999. Most of people (including me) will never read such old documents because most probably many things described there are outdated. - Zope Development Guide full of comments since 2002. This should be refactored once a month, at least once a 3 months (I've seen the effort to rewrite ZDG has been started). - Bug tracking system (issue tracker) is not very comfortable to use. Better to use bugzilla, foxbugs, even 'trac' project will be a way much better and easier to use. And intruducing a better bug tracking could lead to better and faster bug resolution. So, I think zope.org needs good refactoring, but it seems there are no single person working on the site constantly, only from time to time (like plone integration event). Does anyone have any suggestions how this could be fixed? I can try to help, but as you have probably noticed I am not native English speaker, so my help with editing texts will not be very useful. But we can try to find out the problem with hardware/software setup of zope.org to find out why its slow. Possible we can install bugzilla or some other thing.

It was set as 1, now I set it as 5, and the counter is going higher every day. I think I have to delete Sessions.fs every night and restart Zope. Is it expected expected behavior when using file storage? I was thinking that only problem of this kind of storage is the need to pack the database sometimes. That was the intent. You did pack and it didn't reduce the file size? Yes, I packed it, size reduced, but the number of session objects still the same. And keep growing. Today morning stats (nobody works now, people still slepping at England): 12567 items are in this transient object container. Data object timeout value in minutes: 20 Maximum number of subobjects: 5 Yesterday there was only 1 session objects. Now, I am packing ZODB: --- before pack --- Database Location: /home/zope/current2/var/Sessions.fs Database Size: 6.2M Transient Object Container at /temp_folder/session_data 12568 items are in this transient object container. --- after pack Database Location: /home/zope/current2/var/Sessions.fs Database Size: 59.8K Transient Object Container at /temp_folder/session_data 12570 items are in this transient object container. -- Alex V.

Hi Chris, Well, I was also shamed into creating a new implementation of the sessioning stuff that might work better under higher load. Thank you very much for a fast fix/replacement of Transience :) The people that are now having problems should try to replace the file in their Zope software home named lib/python/Products/Transience/Transience.py with this one: http://cvs.zope.org/*checkout*/Zope/lib/python/Products/Transience/Transience.py?rev=1.32.12.2.2.1 (be sure to make a backup of the original file first) I installed new Transience.py. During my little test it works fine. But real test will be on Monday when students start logging in as complete classes, sometimes there are hundreds of them logging on simultaneously, so we will see. I copied original file, so in case of problems, I will put it back and restart Zope. After putting the new file in place, restart Zope and see what happens. This stuff was just checked in, so there's sure to be some edge case bugs, but all the unit tests pass and the UI still works. Please report results back here, if possible. I will report if any problem occurs.

Hi On Tue, 24 Feb 2004, Chris McDonough wrote: Yes, it's still broke. No, there is no fix. Sorry. Thanks Cris. Thats very bad. It is very bad from end-user perspective that such critical bug has been found more then year ago, and nobody at Zope has fixed their code during a year time. I am trying to read all the things you have discussed in March 2003, but it is very difficult to understand how to fix that. Also, I am in doubt I will be able to do that, because if Zope-experienced developers can not fix it, my chances are low. I just have no choice - we already developed a product for Zope, so I have to support it. Even if it requires hacking of application server itself. I see that fix: #db.klass = LowConflictConnection but it does not work for us. At least we keep seeing the session errors with any Zope version - we tries Zope 2.6.4, Zope 2.7.0 with same results. So, as far I you see, as soon as Zope starts using sessions, and when there are many customers, the site is dead for some users. Once 'get' error occurs to a specific Session, the customer is blocked and is not able to see any page on the site: all pages produce this get error. That is very critital and 'blocker' bug for Zope. I do not understand how people could use Zope on a sites with high load.. The only thing which works is asking customer to delete all Cookies, so session ends, and new one starts. This is very ugly fix, you understand... I am not Zope hacker itself, we are just building sites, we are not developers of Server solutions in most of time, so it takes time to study the Zope code to be able to fix that... I will try to work on this more and more, but ... Its just very difficult. Anybody, experienced with Zope developmnet could help me? I am sure, this problem could happend to anyone running a big Zope site. Is anybody interested in helping to resolve this blocker Zope+Sessions issue? As soon as you start getting more hits to any Zope based site, the more customers will not see it because of Session problem. I do not know how many customers of our site getting this, but we do get it everyday several times a day / person. So, in my understanding Zope Session is completely broken. It works fine for a several customers/ hour, but when things come to 1000 visits/ hour, it just stops functionaning properly. I will be trying to study Zope code That is what Open Source for, and I am a big fun of that. But of course, it does not help much if you are not experienced with product itself. It takes time to learn it. But I will try. If anybody interested in help, it would be great. at the current moment I am trying to stable reproduce the prob, but it seems it only happends on a site with high load. -- Alex V.

Re: [Zope-dev] Zope 2.X BIG Session problems - blocker - our site dies - need help of experience Zope developer, please
Hi
As far I understand the error happends in this code
Question to Python developers:
As far I understand, index does contain b, and
data does not contain 'b'.
Simple question: why does the line:
v = self._data[b].get(k, notfound)
throw KeyError at any case? get does have next argument, and if
key is not found, ti will return [], right?
It seems I do not understand Python code at this place. Please advice.
Alex
- [ code from Transience.py ---
def get(self, k, default=_marker):
self.lock.acquire()

DEBUG and TLOG('get: called with k=%s' % k)
notfound = []

Re: [Zope-dev] Zope 2.6.X, 2.7.x sesssion problems, please help (fwd)
Hi, I am not sure, but it if Locking is global thing, I think, that if could happend the following way: 1. some function makes self.lock.acquire() 2. it calls another function, which have 2 calls: self.lock.acquire() self.lock.release() since the locking is done globally, most probably, it will mean that call to _getIndex for example will release the lock, and the processin in upper function will continue with undefined results (most possible _housekeep in different threat will delete the key same time we are trying to read the data). May be I am wrong... Most important now to understand for me why the error persists. It means, that once a user see the Session key Error, the user will keep getting it all the time, on all site, until _ZopeId cookie is deleted for the Session. -- Alex V.

[Zope-dev] ZEO Server Crashed
We have been running our web site with Zope 2.4.2 and ZEO (I'm unsure of the version, can't seem to find it anywhere) for about 5 months. We are running it on Solaris 8 w/ Python 2.1.2.

Re: [Zope-dev] Another Signal 11 Question
This problem still hasn't been resolved. I am using a source distribution of Zope. On our production machine, I only recompiled Python. Since the ZMI was reporting the new Python, I figured that was enough to fix the problem. I suppose I could alleviate one other possibility by recompiling Zope too.

[Zope-dev] aq_inContextOf attribute error
Hello All !
After installing latest stable version of Zope (2.2.4) I tried to
install ZFormulator version 0.2. And as result got 2 problems with
permissions system. First was in ZFormulator itself, and was corrected:
__roles__ = ('manager',)
was changed to
__roles__ = ('Manager',)
but this bug correction worked fine for previous versions of Zope,
and in current version adding of field produced error:
Attribute Error: aq_inContextOf in line 231 of
lib/python/AccessControl/User.py
I am nor Zope nor Python hacker, but I tried to correct this line a little,
and this worked for me. Please advice did I made it correct way or not.
User.py line 231:
Here was the original code (which produced error):
if not parent.aq_inContextOf(self.aq_parent.aq_parent,1):
Here is replacement (added check is attribute exists):
if hasattr(parent, 'aq_inContextOf') and not
parent.aq_inContextOf(self.aq_parent.aq_parent,1):
After this correction everything works fine, but since I am not Zope/Python
guru, but just a user which wanted some program to start working, I keeping
changed locally, but of course I am interested was this correction OK.
Regards.
