[Zope3-dev] zope.etree / zope.webdav
Hi, Long ago I rename zope.etree - z3c.etree and zope.webdav - z3c.dav to move it out of the zope namespace. At the time I seemed to have copied instead of moved the projects in subversion. I only released when Sidnei checked in change to zope.etree. I have just removed them. Aplogise to Sidnei again and to any one else you may have used / be using them. Please use the released z3c.etree or z3c.dav packages instead. Michael ___ Zope3-dev mailing list Zope3-dev@zope.org Unsub: http://mail.zope.org/mailman/options/zope3-dev/archive%40mail-archive.com
[Zope3-dev] WebDAV Future
Hi All, I want to move the webdav implementation on by releasing it to cheeseshop, supporting more content types and then working on some more interesting aspects of the protocol itself, and maybe even supporting other applications like Plone if there is interest. First I need to rename it out of the zope namespace, which was a mistake on my part in calling it this. But this brings up some packaging issues for me that I am not sure how best to do this in a consistent fashion that I can build on. Hence why I have delayed doing anything about this. Currently everything is in zope.webdav. Which includes support for the zope.app.file zope.app.folder content types. Using zope.locking as a locking mechanism and using zope.copypastemove for copying and moving content. Each of the packages just mentioned should be optional (but aren't because of the current setup, which I want to fix). Now into future. I want to split this up into a core Zope3 WebDAV implementation, which will handle registering the different WebDAV methods, their implementation, declaring properties, exception handing which I could call z3c.webdav. This module / egg on it own will be pretty useless, as it doesn't know about any of the content or services in Zope3. Then I want for each content type and services in Zope its own egg so to speak, for example z3c.webdav.zopeappfolder, z3c.webdav.zopeappfile, z3c.webdav.zopefile, z3c.webdav.zopelocking. A lot of these extra eggs will be small and easy to write, and as more content types are supported by Zope3 I would like more webdav modules to be written for them. An other two options I can think of, instead of the naming convention above: 1. create a webdav namespace, webdaz (WebDAv for Zope), which would contain webdaz.core, webdaz.zopefile, webdaz.zopelocking etc 2. Name the core webdav implementation z3c.webdav and then create eggs that are named like zope.file.webdav (for zope.file), zope.app.file.webdav, z3c.extfile.webdav, zope.locking.webdav etc. but which are separate from the underlying module. Does any one have any experience with this type of problem or does any one of a preference to which one they like best. Or is there other options that I have missed that is worth considering, in order for me to move this forward. Thanks, Michael P.S. after writing all this down my preference is moving towards the last zope.file.webdav, etc. ___ Zope3-dev mailing list Zope3-dev@zope.org Unsub: http://mail.zope.org/mailman/options/zope3-dev/archive%40mail-archive.com

With this you have no clue - whether the object or the object's annotations were modified - which properties of which schema were modified. The good news is that the ObjectModifiedEvent API actually supports this kind of stuff, you just need to use it: info = Attributes(ITheSchema, 'foo', 'bar', 'blergh') notify(ObjectModifiedEvent(obj, info)) (Attributes is importable from zope.lifecycleevent). Note that the object must not necessarily provide ITheSchema, it could also be that the ITheSchema(obj) adapter was changed (this is useful when sending modified events for annotation adapters like IZopeDublinCore). Very interesting - I never even knew you could do this :-) All modifications made by the PROPPATCH will be done via the adapter lookup you just mentioned so it is really nice that this is supported. Unfortunately, not many places in Zope 3 itself are good examples of this. In fact, not even formlib sends this extra information along with the events, something I've been meaning to report and fix. (Thanks for reminding me to do so :)). Thanks for the tip, I will definitely update webdav to use it.

If this isn't fixed soon, I'm going to advise to the maintainer of the 3.3.x line to back out the change that led to the test failure so that we can assure all of the Zope 3.3 users out there that we're indeed fixing bugs and releasing the fixes. Zope 3.3.1 has tons of other bugfixes that people out there are waiting for. I hope we won't have to resort to reverting the zope.app.twisted change. The thing is I don't know what as changed in the twisted code. I recently updated Twisted on the trunk - but I didn't put this change onto the 3.3 branch.

[Zope3-dev] Twisted Upgrade
Hi All, Jim brought up the issue on IRC that I have known about for a while now that Twisted in Zope3 really needs to be updated. There are few other related issues that need to be sorted out apart from getting Zope3 running and all its tests passing. So I propose: 1. SFTP - lets just rip this out - it doesn't work and I don't have the interest to carry this any further. 2. Tests. I added code to zope.app.twisted to make the Twisted trial tests run within the zope testrunner (these are needed to test the Twisted / Zope3 FTP integration). But in later versions of Twisted trial does run, without modification, in the zope testrunner. So I propose adding tests to zope.testing to make sure that this still is the case - as there is nothing more annoying then tests that always pass no matter what happens. This wouldn't change any functionality of zope.testing but will just be a few extra tests that get run only iff twisted is installed. 3. Don't use an external branch, but import a Twisted release into the Zope repository. This was brought up before by some one after the Twisted subversion server went down and the Zope buildbot failed. A while back I got Zope3 running with the Twisted trunk and the tests passing with some changes to Zope. So over the weekend I will plan to make a branch available with the goal of getting all the work done so far out there and to get on with the rest of the issues. Any other issues, questions on this topic? Michael ___ Zope3-dev mailing list Zope3-dev@zope.org Unsub: http://mail.zope.org/mailman/options/zope3-dev/archive%40mail-archive.com

I then looked into this 1 / 2 weeks ago and then I remembered how painful this was. The issue, or part of the issue, is that the WSGI specification says that: The optional size argument to readline() is not supported, as it may be complex for server authors to implement, and is not often used in practice. I have managed to patch cgi.FieldStorage up with a work around which I sent to the web-sig mailing list and which I have finally got around to creating a new bug report for python after seeing your checkin - see http://sourceforge.net/tracker/index.php?func=detailaid=1573931group_id=5470atid=105470 The sole response on web-sig mailing list was to change the WSGI specification. But I wonder how many other WSGI applications are effected by this. If it just Zope and Twisted then changing the specification should be ok, otherwise things could get very messy for WSGI.

Re: [Zope3-dev] Was WebDAV locking implemented?
Hi Jim, no - don't think I implemented it anyways.

This part is turning out really difficult to get right. This has extended to other areas of the code has it is in my branch, so in a nutshell you could say that I have gone and started from strach :-) It is getting back to a resonable state, just one more big problem in handling errors to get over, then I will attack the locking problem.

What are you planning to do with the locking stuff? I'd like to see zope.locking (http://svn.zope.org/zope.locking/) used, rather than zope.app.locking. It learns from zope.app.locking while also addressing some issues and adding some features. I don't have time to do much about proposing it and integrating it, though. Maybe I can squeeze in a bit next week or week after. Brillant - Locking is next on my hit list, and I am planing on using zope.locking to improve the current implementation. I have an issue with zope.locking on a collection with infinite depth but I am planing on ignoring this use case for the moment and get the rest of the locking working without any infinite depth support and like yourself I am going to quite busy over the next few weeks so it will probably be slow in coming. But I would appreciate what you think about this particular use case. Some background: The current webdav spec RFC2518 will hopefully be deprecated in the next few months. The new specification which has just in the last fortnight gone into last call stage of development, contains a near rewrite of the locking sections to make things easier (so they say), especially relating to the lock null resources and locks on collections. And I am aiming at implementing these features as it is what apache does and I get the impresion that the writers of the spec have clearly learned from past problems implementing this feature. But one thing the new spec goes into that zope.locking doesn't have (I don't think) is when you lock a collection with infinite depth. The new specification says that the collection and all the descendents objects are to locked against one lock token. The collection been locked is called the lockroot and all descendent objects are then indirectly locked against this lock token. The specification goes on to say that if an object is added to such a locked folder then it is also automatically indirectly locked against the same lock token has the folder. Any successful unlock operation on a locked object must also unlock all resources associated with this lock token. (Sorry I the previous paragraph isn't completely clear but section 6.1 and 7.4 of http://www.ietf.org/internet-drafts/draft-ietf-webdav-rfc2518bis-14.txt explains this feature a lot better if I didn't make sense) Any ideas on this?, is it feasible or not within zope.locking? If Jim successfully gets zc.sharing open sourced today then we have some zope.locking/zc.sharing integration that (as one integration option for zope.locking tokens) can filter so that only people with locks have edit privileges. It seems to work pretty well, but it's also just one way to use the zope.locking tokens. As with zope.app.locking, the locks themselves are purely advisory until you put in some code to make them enforced somehow. Can't wait. zope.locking can do exclusive lock tokens, shared lock tokens, freeze tokens (effectively, no one gets the lock), and can also support custom tokens if you need them.

[Zope3-dev] WebDAV
Hi All, I have being quite busy lately trying to improve WebDAV support for Zope3. To this end I have two proposals worth your consideration. I don't yet have access to the proposals area of zope.org but I have put them up in my home folder on zope.org for the time being. They are: WebDAV Interfaces, Widgets and Adapters http://www.zope.org/Members/mkerrin/WebDAVInterfacesWidgetsAndAdapters This defines changes that I see has crucial but which introduce nasty backwards compatibility problems. So it would be handy to know who has developed any custom extension to zope.app.dav be it a custom adapter to zope.app.dav.interfaces.IDAVSchema or who have developed a custom WebDAV namespace (these are the two likely areas for problems). I am hoping that this figure is small :-) WebDAV? Namespace Management http://www.zope.org/Members/mkerrin/WebDAVProposal/wikipage_view Here I define how, and why, I am planning to manage a WebDAV namespace. This includes how to find which properties are defined on a object, and what widget to use to display the property, and how to extend an already registered WebDAV namespace. My goal for all this has being to develop zope.app.dav to a point where it can handle all of the WebDAV protocol details according to the RFC2518 specification, while only requiring a minimal knowledge of WebDAV from developers who just wish to integrate WebDAV protocol into there application. Also I have being doing a lot of reading of specifications and by using these changes I hope to begin development of other WebDAV protocols once I have finished with the core WebDAV support. Hope you like it, and any improvements / comments will be most appreciated. Michael -- Michael Kerrin 55 Fitzwilliam Sq., Dublin 2.

Re: [Zope3-dev] zope.app.twisted.ftp tests
Hi Jim, If you are happy to wait a few days more, before including these into buildbot, I will create a branch to get these tests back into the same zope testing framework. From what Andrew Bennetts said in his response, this is very possible but will probable require a update of Twisted to the trunk. But then we can do what we are doing now and just have svn:external pointing to a specific revision of the Twisted trunk.

I am thinking that it would be a good idea to include these tests as part of the buildbot process, just after all the standard zope tests have run. It means that if some one apart from myself has to make any changes to the zope.app.twisted.ftp module, they will learn pretty quickly if something has broken, or if the Twisted external is updated. I have no idea on how / who to ask for this. But to run the tests we just have to run in the same place has the standard zope tests: ./trial.py zope.app.twisted.ftp.test There is a --reporter argument to this trial program that can take one of the following values bwverbose, text, verbose, or summary to control the amount of output. I hope this isn't to difficult to add in. I'll look at adding this. Jim -- Michael Kerrin 55 Fitzwilliam Sq., Dublin 2.

[Zope3-dev] zope.app.ftp, security, adapters
Hi All, I am having a problem with permissions and security in zope.app.ftp The writable method in FTPView basically uses adapter lookup on IWriteFile and tests this adapter if it has a 'write' attribute in order to test if a user can write to the specified file. The problem is this seems to be always true (assuming the user has permission to list the names in the directory otherwise an Unauthorized exception is thrown, (this is my next problem to fix). The adapter configuration for IWriteFile in zope.app.file has the permission of zope.ManageContent on it. But has far has I can see this permission is only tested if, in this case the write method, is called. So how do I get this writable method to work correctly, by reimplementing it or via some ZCML trick that I am unaware of.

I don't have experience with Twisted, so don't know what to try. If you can point me at a patchset, happy to try it on Windows any time. AFAICT, the Twisted-related failures were the only ones remaining on Windows when I left off yesterday. I have just changed the svn:external for Twisted to a more stable 2.1 branch which should contain the fix for the Windows problem you reported. I still haven't checked Zope on windows yet because of a problem in the with FTP but I have being assured that it will run. I will check the buildbot link you sent in the morning and see what the status is then, fingers crossed.

Re: [Zope3-dev] zope fails to start
This has just being fixed. Just run 'svn up' in your z3 directory and Zope
should then start.

Most seem related to twisted, and may ultimately stem from that there is no fcntl module on Windows. Agreed - I am assuming then from looknig at the trace back that Zope is not starting because of this. I don't have a Windows box handy to run this myself. I have just created a bug report for the Twisted guys at http://twistedmatrix.com/bugs/issue1270 and I am about to ask them about another problems we should be ware off about running twisted on windows. The buildbot hasn't been of any help here, since the Windows box has failed during its initial svn step non-stop since last Friday: http://buildbot.zope.org/ (Nice - I didn't know about this) where every run on Windows 2000 fred-win dies in its checkout step with Failure: exceptions.AttributeError: ShellCommand instance has no attribute 'commandFailed' This seems to be buildbot itself. The Failure in test doctest_RecordingProtocol (zope.app.recorder.tests) looks unrelated to twisted; I'll take a look. OK. The profiling.txt failure is (still) due to using a Windows-buggy snapshot of zope.testing. I see the new functional-test warning RuntimeWarning: PyCrypto not installed, but continuing anyways! on Linux too. Is installing PyCrypto now a prerequisite for Zope3? PyCrypto is required if you want to run HTTP over SSL. If you don't want to do this then this can be safely ignored.
