For Zope2 we're used the x in 2.x.y being the major version now anyway, the next release should be 2.14. Lets stick with our convention until we have something that we really do want to promote to users outside the existing development community, I expect that will be a few years away yet. I fully agree with that. A major version of Zope 2 is actually a minor at the version meaning, but everybody knows that for instance to switch from 2.10 to 2.11 you have to review and update your code like if it was a real major version change at the version meaning. That would be really confusing to do otherwise, since it was like that for years. I am also in favor of dropping the 2, but picking a new name would be nice, like to have 'framework x' 10 that map to Zope 2 2.10, 'framework x' to 2.11.

If we still have that minimalistic ZMI, all players in our community can decide how much effort they want to spend maintaining which legacy pieces technology, depending on what makes economic sense to them, without causing extra maintenance burden on the other players. I think the problem with the current ZMI is that it brings in a whole load of dependencies that we don't otherwise need - if it were minimalistic it wouldn't be a problem.

Over the next few years we will need to start moving to Python 3, and the only way to make that port possible is by reducing the size of the codebase. As a Plone developer, my interest is in how we make Zope into something that enables Plone to continue evolving and developing, to port to Python 3 and increasingly use more standard WSGI components. Rewriting in Pyramid is not an option for us, large rewrites generally fail (even if they do produce excellent new technology along the way...) Of course if people who have legacy applications want to continue maintaining a 'Classic' Zope 2 in it's current form then they are free to do so, but it won't happen without investment on their part. I expect they will have similar concerns to the Plone developers, and may find the same reduction and evolution approach to Zope useful.

It doesn't seem to conflict with your stated goal: I think having a minimal database browser is a good idea. I think something like https://github.com/davisagli/eye is the right starting point here. I don't want to have anything that lives in the same process as the rest of the application code. The ZMI is currently like running phpMyAdmin accessible to the world with the same credentials and on the same domain as the rest of your application. It's a huge security risk and pollutes model classes and views in the application code. Or to put it differently, in which way does having a minimalistic OFS browser for a ZMI conflicts or hinders Plone's objectives for the Zope2 code base? The ZMI is a highly insecure, completely outdated and user-unfriendly interface. On the security level, there's no validation of user-input, there's no XSS and CSRF protection. Anyone being logged into your application who has ZMI access is susceptible to a large number of attacks. There's too much of stone-age code based on no-patterns to prevent these attacks - we can currently only fix them in a tedious process of finding one exploit after the other. We need a better strategy here - and the only one I can see is removing the existing ZMI code and moving any low-level interface to a completely separate codebase and process. On the other points, at least Plone tries to use modern web technologies and for example we just switched to a HTML5 doctype - having any end-user go to the ZMI and look at a frames-based interface undermines any marketing message we try to put out about being modern. And then the ZMI doesn't even do basic things like asking you for confirmation before removing your entire site and being in almost all regards a huge usability fail - again completely add odds with Plone's good end-user usability story. On the code level the ZMI-support code is mixed into all other model code and has often lead to arcane developer API's. There's far too many places where a manage_* method with a request argument is the only way to achieve anything. For whatever code we'll end up with in two to three years, I want to see good developer API's that actually make you productive. I hope this clarifies a bit more, why I feel the ZMI is an arcane beast that needs to be hunted down sooner than later.

Hi, this is my first posting on the list, so please be kind if i make some mistakes ;-) On Sun, Jul 3, 2011 at 1:03 AM, Leonardo Rochael Almeida leorochael at gmail.com wrote: I noticed you've been very busy doing clean-up on the Zope2 code base in the last few hours. As someone who has recently spent a lot of time porting forward a large and mission-critical code base, ERP5, from Zope 2.8 to Zope 2.12, I'm a little confused about the direction that you're moving, and how much effort that could mean for future porting efforts for Nexedi. I think moving to Zope 2.12 and 2.13 does have some value for Nexedi or other large existing codebases, as you get support for current versions of the ZODB, Zope Toolkit packages and support for Python 2.7 with Zope 2.13. Since Python 2.7 is a long-term maintenance release for Python itself, this should provide a stable and good basis for the next years - the statements from the Python community aren't completely clear - but I'd expect to see ongoing maintenance until 2013 or maybe even 2015. Going forward I can see two paths for Zope 2. Either we don't touch it at all anymore and let it bitrot or we try to move it forward and adept it to current best practices of development. Since complete rewrites almost always fail, like we have seen with Zope 3 - I prefer changing Zope 2. I agree with you. Evolution is better then revolution. If you are interested in stability I think sticking with an older version of Zope 2 is a completely sane and good approach. OK, so you do think that we might use Zope 2.12 for a quite long time without thinking about anymore updates? Will there be any security updates for Zope 2.12 in the future? What me and others from the Plone community are trying to do with the Zope 2 codebase is to actually move it forward. We can either do that as part of the official Zope 2 release series or fork the codebase. Since so far there isn't really anyone else interested in working on the Zope 2 codebase, we keep changing Zope 2 without forking it. Unfortunately i am not really able to help or work on the codebase, but we are using Zope 2.x for several years now. But can you explain to us a little of how you expect Zope2 to behave with the changes you're doing? There's a number of things I want to do. Not sure when I'll or others will have the time, but these are things I expect to happen in the next months or releases: - Continue to remove functionality tailored for TTW development, like SiteRoot, AccessRules, HelpSys and step-by-step most of the ZMI OK, we're not using any of the stated functionality, but what is the reason for removing most of the ZMI? - Document and use the WSGI publisher and remove obsoleted functionality like the virtual host monster, error_log, ZServer/medusa, zopectl/zdaemon We are using the virtual host monster (at least one per instance), we are using the error_log as well in all our applications. Are there any alternatives already? - Make the browser id manager, session data manager, temporary storage optional and remove it and request.SESSION from the core, instead we can use something based on Products.BeakerSessionDataManager / collective.beaker if someone has a need for sessions Hmm, i am not that much into Zopes structure, but if we are using request.SESSION we are in the need of the browser id manager, the session data manager and the temporary storage as well, right? - Start using and storing parent pointers and remove Acquisition.Implicit from the most common base classes (a branch for this already exists with almost all core tests passing) Does this mean, if i want to use a DTML method in a folder structure like this: /a/b/c/d/e i will have to know which level the method exists? We are using a lot of methods stored in folder a but used from folder b to e... Or can you give me a short explanation about what Acquisition.Implicit does? - Merge five.pt (Chameleon) into the core and use it instead of the zope.tal/zope.tales implementation (which means no more RestrictedPython for templates) - Once most of the ZMI is gone, it should be feasible to drop DTML or rewrite what little is left as page templates Now i am completely shocked. We are building web applications for the last 6 years in Zope 2.x. All those applications are using the following techniques: - DTML method/document - Z MySQL Database Connection and Z SQL Method - MailHost / MailDrop Host - RAM Cache Manager - acl_users User Folder - Script (Python) - External Method - error_log - File, Image, ExtFile and ExtImage - REQUEST / REQUEST.SESSION - Virtual Host Monster - Browser Id Manager - Session Data Manager / Session Data Container - Temporary Folder This would mean to migrate at least one hundred projects from DTML to TAL/ZPT?

I think it would be a better use of resources for anyone to start doing that than maintaining a dead-end. This is a pretty sweeping statement that I think could cause a lot of nervousness. It might be the right thing in many ways, but we need to at least provide a bit more context. If you're a business that's invested dozens of person-years into a product, the prospect of rewriting could seem fairly daunting. At least we, as the Zope 2 community, need to set out the case for change and some kind of idea of timing and transition path, even if that means in some cases getting to a long term maintenance release and in other cases evolving away from certain technologies whilst being confident to keep using others.

I'm willing to cut releases for it for quite a while. I just expect to see active maintenance from the Plone community to stop in a year or two. Judging from the ongoing maintenance we currently have for Zope 2.10 or 2.11 I don't think it's very realistic to expect much to happen once the Plone guys stop. What I'm outlining here has of course almost nothing to do with the original idea and scope of Zope 2. Maybe at some point this should get a different name ;-) I don't want to discuss names, but I think the next release from Zope trunk should be explicitly a new *major* release.

Yes. I'm willing to cut releases for it for quite a while. I just expect to see active maintenance from the Plone community to stop in a year or two. Judging from the ongoing maintenance we currently have for Zope 2.10 or 2.11 I don't think it's very realistic to expect much to happen once the Plone guys stop. What I'm outlining here has of course almost nothing to do with the original idea and scope of Zope 2.

Or do you think we can stick with Zope 2 but change the way of building applications to ZPT/TAL? So we have to get rid of all DTML and what about an alternative to the ZSQL Methods? How long Zope 2.13 is going to be supported and sees security fixes will depend on the community. The Plone community will use it for its 4.1 and 4.2 releases, as a result of our security policy that should result in us supporting Zope 2.13 for the next two years. Beyond that nobody knows what will happen. I do agree. Now i am completely shocked. We are building web applications for the last 6 years in Zope 2.x. All those applications are using the following techniques: [snip] What you are describing is exactly what I meant by old legacy Zope2 applications. You should be able to use this style of development with Zope 2.13. But you won't be able to upgrade to newer versions of Zope 2 anymore and expect your code to work unmodified. We discouraged this style of development for the past six years. It should come as no surprise that it will come to an end at some point.

The ZMI is not a package - we don't have a split into zope and zope.app in Zope2. Once there's no more ZMI, Products.PageTemplates stops using RestrictedPython and the OFS base classes don't inherit from Acquisition.Implicit anymore, it'll be really hard to keep the legacy development approach working. I think it might be useful to spell out the reasons behind this (here, or better yet, somewhere more permanent like zope.org http://zope.org). I can imagine people reading this and wondering why it's a good idea, especially those who have an investment in the existing technologies. Someone might try, but I think it's not a wise decision to spent any resources that way. At some point every application written in the legacy style has to be rewritten. I think it would be a better use of resources for anyone to start doing that than maintaining a dead-end. This is a pretty sweeping statement that I think could cause a lot of nervousness. It might be the right thing in many ways, but we need to at least provide a bit more context. If you're a business that's invested dozens of person-years into a product, the prospect of rewriting could seem fairly daunting. At least we, as the Zope 2 community, need to set out the case for change and some kind of idea of timing and transition path, even if that means in some cases getting to a long term maintenance release and in other cases evolving away from certain technologies whilst being confident to keep using others. I agree with Martin, that a sane upgrade path should be provided at least. If people still use things like DTML, the ZMI, etc., then it would be highly frustrating for them to simply drop these. You can split the components from the base and provide them as optional where possible. This seems to be possible with most of the components that Hanno listed as depreciated/to be removed soon. And most importantly: provide sane upgrade paths for depreciated components. If the ancient session management from Zope2 is to be dropped, tell people what they should use instead, and how to migrate their old_but_still_in_use applications/projects.

Once there's no more ZMI, Products.PageTemplates stops using RestrictedPython and the OFS base classes don't inherit from Acquisition.Implicit anymore, it'll be really hard to keep the legacy development approach working. I guess this is the biggest point of contention. Why does the ZMI have to go?

That's the kind of scope that should be possible to port to Python 3 and actually modernize enough to be understandable.(...) Or to put it differently, in which way does having a minimalistic OFS browser for a ZMI conflicts or hinders Plone's objectives for the Zope2 code base? If we still have that minimalistic ZMI, all players in our community can decide how much effort they want to spend maintaining which legacy pieces technology, depending on what makes economic sense to them, without causing extra maintenance burden on the other players.

Yes, these were the reasons we ported to Zope 2.12 to begin with. Going forward I can see two paths for Zope 2. Either we don't touch it at all anymore and let it bitrot or we try to move it forward and adept it to current best practices of development. Since complete rewrites almost always fail, like we have seen with Zope 3 - I prefer changing Zope 2. Agreed. If you are interested in stability I think sticking with an older version of Zope 2 is a completely sane and good approach. What me and others from the Plone community are trying to do with the Zope 2 codebase is to actually move it forward. We can either do that as part of the official Zope 2 release series or fork the codebase. Since so far there isn't really anyone else interested in working on the Zope 2 codebase, we keep changing Zope 2 without forking it. With the direction the Zope2 codebase has taken so far, I don't see any reason to fork it even if all current players keep depending on it. But can you explain to us a little of how you expect Zope2 to behave with the changes you're doing? There's a number of things I want to do. Not sure when I'll or others will have the time, but these are things I expect to happen in the next months or releases: - Continue to remove functionality tailored for TTW development, like SiteRoot, AccessRules, HelpSys and step-by-step most of the ZMI - Document and use the WSGI publisher and remove obsoleted functionality like the virtual host monster, error_log, ZServer/medusa, zopectl/zdaemon In ERP5, we've made TTW development sane and safe, and integrated with VCSs (both SVN and Git), so the above paragraph sounds a little bit scary, though in reality it doesn't have to be. SiteRoot, AccessRules, HelpSys, of course, are really unused, so I don't fear their disappearance. As for the rest, most of the things that have been removed from core were done in such a way that they can still be used with Zope2, so ERP5 can happily keep using them. If things can keep evolving with this care we should be ok. As others have pointed out, the core url rewriting functionality of VHM is useful even in a WSGI context, and I'd argue that it should actually be made part of the root Application, so that we don't need a persistent object just for this. On the other hand, if we could get the ZTK version of this working (the one that used /++vh-host and /++vh-root url segments) I think it should be ok, and we could get rid of VHM completely. - Make the browser id manager, session data manager, temporary storage optional and remove it and request.SESSION from the core, instead we can use something based on Products.BeakerSessionDataManager / collective.beaker if someone has a need for sessions - Start using and storing parent pointers and remove Acquisition.Implicit from the most common base classes (a branch for this already exists with almost all core tests passing) ERP5 will probably get rid of all its uses of acquisition too at some point. We've recently taken a large step in this direction, but again, it can still be used as an add-on, so this is not a problem. - Merge five.pt (Chameleon) into the core and use it instead of the zope.tal/zope.tales implementation (which means no more RestrictedPython for templates). A few months ago, I and Malthe did some work to make sure that TTW ZPTs worked with five.pt. Malthe even surprised me with something that I thought couldn't possibly work and managed to get the RestrictedPython evaluator to translate python expressions in TTW ZPTs. So, getting rid of RestrictedPython is not strictly necessary for using five.pt in Zope2 core. Then again, we might decide to get rid of it for other reasons... Anyway, as long as there are still TTW addable ZPTs, PythonScripts and ZSQLMethods, ERP5 can still work. - Once most of the ZMI is gone, it should be feasible to drop DTML or rewrite what little is left as page templates If DTML is still available as an optional product/package, this should not be a problem for us, but we'll likely depend on ZSQLMethods (hence, on DTML) for a long time, since our ZSQLCatalog functionality is built heavily around it.
Re: [Zope-dev] direction
Something of a meta-comment on this thread: It sounds like people are broadly in agreement on the direction, but not communicating enough about what's actually going on. I think it would be useful to keep some kind of roadmap wiki on zope.org, or at least post to the list periodically saying, this is what we're about to start doing.
