Re: [Zope-dev] [ZODB-Dev] RFC: release persistent as a standalone package
I would like to release a '4.0.0' version of the package, and switch the ZODB trunk to pull it in as a dependency (deleting the currently included (older) copy of persistent). One possible issue is that I have not (yet) made the C extensions work under Python 3.2: I don't know whether that should be a blocker for a release. I do not believe its a blocker. That is a feature that could be added. Comments?

[Zope-dev] zope.testrunner misleading output
Hello, I've tried submitting this as a launchpad answer but it expired without further notice; I'm posting this here, I hope it's the right place to discuss this. I'm indirectly using zope.testrunner through zc.buildout zc.recipe.testrunner: [testunits] recipe = zc.recipe.testrunner eggs = pydenji defaults = [ --auto-color, -vv, --tests-pattern, ^test_.* ] It works; but what happens if a test file matching the pattern has got a serious failure, let's say an import or syntax error ? Output: Test-module import failures: Module: pydenji.test.test_cmdline File /Users/alan/Dropbox/code/pydenji_release/pydenji/pydenji/test/test_cmdline.py, line 13 ^ SyntaxError: invalid syntax Running tests at level 1 Running zope.testrunner.layer.UnitTests tests: Set up zope.testrunner.layer.UnitTests in 0.000 seconds. Running: [...] long test output [... ] test_resolver_retrieves_package_resource_filename (pydenji.test.test_uriresolver.TestPackageResolver) Ran 73 tests with 0 failures and 0 errors in 0.188 seconds. Tearing down left over layers: Tear down zope.testrunner.layer.UnitTests in 0.000 seconds. Test-modules with import problems: pydenji.test.test_cmdline I can't show you such things here, but the 73 is green, which is the colour for all ok - if any failure happens, the colors turn red, while the test modules with import problems are just a tiny line after that, and often gets overlooked. Also, a test file matching the pattern but which not defines any test is treated the very same way as a file with import problems, which is probably not what it want. The issues I can find are: - I need to dig to the top in order to get the traceback; other frameworks, like twisted's own trial, print all the tracebacks at the bottom of the test run for easy debugging; - test colors should not turn green if any test with import problem is around; maybe an import/syntax error should count as a generic error. - while an import issue is a serious fact - meaning the test can't be run, and should be reported, a test module which does not define any test could just issue a warning - it could just be a placeholder test, or a not-yet-finished test case, and should not be a blocking issue.

Yes, the status code is correctly set - I wasn't complaining about that, the runner works fine in our CI system - but I usually don't pipe || while running tests at the console. Also, there's a bit of impedence between 0 failures and 0 errors and the exit status 1. I mean, the first time it happened i thought WTF?. I mean: it's very easy to associate red with something bad occurred, I like that, and I'd like that to be extended. Maybe something like Ran A tests with B failures, C errors and D other problems would satisfy us all. That's an interesting perspective. Note that even when there are failures, the number of tests and the number of seconds are highlighted in green. (The colours there are mainly to make the numbers stand out so they're easier to notice in the output.) Yes, you're right, it's just the number of failures that turns red, if any. What I'd probably like is to have failed imports and syntax errors to be counted as errors, while files defining no tests just as warnings. probably not what it want. What's it? it = I , sorry, my typo. - I need to dig to the top in order to get the traceback; other frameworks, like twisted's own trial, print all the tracebacks at the bottom of the test run for easy debugging; Having used other frameworks, I appreciate zope.testrunner's eagerness to show me the traceback at once, so I can start examining an error without having to stare at an F in the middle of a sea of dots and wonder what it might be, while waiting 20 minutes for the rest of the test suite to finish running. I realize zope.testrunner layering system is designed to run unit, integration and maybe acceptance tests, which can be pretty consuming. I usually run mostly unit tests, taking less than 2 seconds. By the way you're describing nose behaviour, I think; twisted trial is better at this; normally it just outputs the errors at the end, but if the -e switch is passed, it prints the tracebacks both ASAP *and* at the end. I guess a similar approach, using a switch, could be employed in zope.testrunner. Then again I agree that having to scroll back to the first traceback is a necessity that's a bit bothersome. I don't think printing the tracebacks at the end of the run would help, in case there were multiple tracebacks -- you'd want the first one anyway; the others likely being caused by it. Also, tracebacks tend to be long, requiring me to scroll anyway. If I'm running unit tests there's no certain connection between tracebacks, and most probably there's no definite first. Again, probably a configurable switch would make everybody happy :-) - while an import issue is a serious fact - meaning the test can't be run, and should be reported, a test module which does not define any test could just issue a warning - it could just be a placeholder test, or a not-yet-finished test case, and should not be a blocking issue. An import error could be a placeholder as well. What makes a module with no tests different? If you added a module, it's reasonable to assume you added it for a reason, and what other reason could there be other than for it to have tests? An import error is surely an error; if it can't be imported it can't work in any way. The file might define 100 tests, and those are not run. A syntax error is surely an error as well; if written with the correct syntax there might be tests inside, and they won't get executed. A file defining no tests may be an error, but you can never be sure; hence I think you should tell the user but you shouldn't fail by default, IMHO. NB: if any of my proposal is accepted, I'm willing to contribute a patch, I just don't want to start coding for something that might later just be trashed. -- Alan Franzoni -- contact me at pub...@[mysurname].eu ___ Zope-Dev maillist - Zope-Dev@zope.org https://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope )

[Zope-dev] ZODB Documentation Fundraising
The blog: http://zodbdocs.blogspot.com/ I am coordinating an effort to have a ZODB book written by one of our Zope clan, Carlos de la Guardia. He has completed a recent book for Packt publishing on Grok. He showed interested in writing a ZODB book if it were under Creative Commons. I have set up a blog and focused on behind-the-scenes coordination required to make the book happen. We are now at a point where: - There is an initial outline of topics to cover. - There is a way to contribute financially on the ZODB Docs Blog (through paypal). - If you can contribute to the book with written material and experience. Let me know. I will make a contributor on the blog and you can post articles. Carlos is more than happy to consolidate/pinch material (and of course give the original author credit) and put it into the final book. One of the thoughts would be to write ZODB mini-howtos/articles on the blog. Some initial ideas: transaction module (datamanagers, aftercommithook, etc), debugging scenarios (how to debug a record being mutated accidentally), conflict resolution (writing your own custom impl, btree bucket splits, etc), concurrency, any benchmarking information you have, relstorage, writing your own persistence format (keas.pbpersist?), or query strategies for ZODB. There is a lot of material to cover in this book. - There are also contribution/funding levels available which correlate to recognition of your donation in the book. That is right. Give money and you go down in history in the documentation *wink* We will have a revised outline of the book by Monday evening from Carlos. If you want to contribute material to the Blog -- let me know. You have a channel to voice your experience. More information is on the blog and will be updated as more progress is made. Again the blog is at, http://zodbdocs.blogspot.com/ -- please sign up and subscribe to the RSS feed. I am open for any feedback.

Re: [Zope-dev] Uses of the ZTK and how it relates to management
One thing that makes problems like this really hard is that email is such a terrible tool for much of the needed communication. It would be nice if we could do something more sprinty. I don't want to help if it involves drawn out email discussions, but, FWIW, I'd be willing to allocate some concentrated blocks of time for high-bandwidth discussion and work. Fortunately there are all sorts of free/cheap ways for high bandwidth communication. Maybe a free conference call + screen sharing. If there was an agenda -- I would be more than willing to schedule, ensure technology is working, and coordinate people being there. Some people in the plone community have been doing weekly sprints. They just completed their 27th weekly sprint. They spend 6 hours or so on a set of bugs in the issue tracker. They do it over #irc. By this is still lowbandwidth communications. Nothing better than voice + supporting visuals to increase effectiveness. Again if someone wants to setup agenda I can help w/ logistics and ensure voice/screen sharing will work for, say, 20-40 people. Unfortunately I know very little about ZTK and the dependency issues.

[Zope] help with detecting mime_type
Dears, In my external method I can get mime_type = file.headers.headers[1].split()[1] and then my code proceed based on which mime type was identified for the file uploaded. What happens now is that a user uploading a tgz file from a Windows platform and then my code did not identify it as a application/x-gzip-compressed or similar (it gets application/octet-stream). As far as I understood from this case, such mime type info is passed by user's system (where Windows usually is not aware of tar.gz, tgz etc format) rather than being set by zope server. So since I was not aware of that, my question is: does anyone know a better and reliable way of identifying a file mime type (or a file format) independent from which platform/browser it is submitted? I realise I can use a conditional for checking extension file name in addition to mime type detection. But I would go for that only if I cannot find anything fairer. Many thanks in advance.

[Zope] presenting content in Zope generated outside
Dears List-mates, I have a program that process some data analysis and it's able to generate html docs to be visualised in a web browser. What I am trying to figure out is a way of wrapping this external html docs inside Zope/Plone. Trying to explain it better: I would like to present such data analysis results (and for that I can play with its code in order to generate just the body block for example) as if it were part of our plone website, i.e. using our website's layout with its header and side columns etc. That external data (and html doc) is accessible via LocalFS among others reasons because they are big and temporary. I am aware of importing html via FTP or webdav or even considering to code a python external method to generate the data analysis results independently of my external program, but I guess these approach involves using a lot of ZODB resources, besides processing time, that frankly I would like to avoid. Accessing data via LocalFS or similar and just turn them presentable inside a zope website seems to be the natural way, but I am missing how to do it. I thought about using frames, but it sounds even worse. BTW, is Zope able to work with frames? Another possibility I imagined was if I could fill my external html files with '!-- @import ...' inside e.g. head block, but I really don't know how far I can go with that idea, since my first tests showed me that it can works for font style (*.css files) but then I don't know what else to do, for example, to get the side menu and calendar. Anyway, any commentary here would be very appreciated. Sorry if I couldn't express me better but I am prone to extend any point here if you wish. I thank very much in advance any help.

[Zope] Re: open image in a fitted new window
Thanks Tres and Tino.
BTW Tino, what do you mean with
...or uses layers the big view on top with little DOM action (preferred)...
something like passing the mouse point over the picture and have the
full-size version of the image?
Cheers,

The only trick here is to get the javascript to include the dynamic

I usually use for that::
!-- assumes that 'image' is bound to an actual Zope image object --
script type=text/javascript lang=JavaScript
tal:define=img_url image/absolute_url
tal:content=string:var img_url='${img_url}';/script
Your popup javascript can then refer to the 'img_url' JS variable to set
the window location.
A little bit cleaner approach would be to have an ordinary link:
a class=magnify href=path/to/big/imageimg src=path/to/thumbnail
width, height ... //a
and have a general javascript which scans thru the DOM after load,
finds the a-objects with class-attribute magnify and installs
an handler for mouse click which overrides the usual link action
and either pops up a window or uses layers the big view on top
with little DOM action (preferred). You dont even net buzzy Ajax
for this. The URL for the big picture is just encoded in the HTML
already, so you can use the usual tal: attributes to define in
ZPT.
The result is clean xhtml code which works in any case and only
is improved in case of javascript beeing available.

[Zope] open image in a fitted new window
Dears, I was wondering how to once clicking on a image (thumbnail) I would get the full-size image in a fitted new window, without buttons, address field etc. I can realise how to do it with javascript but I don't know, if it's the only way, how to integrate javascript in a zpt.

So I took a look at LocalFS code and then I commented out line 66 (# ITERATORS_PRESENT=1) forcing LocalFS to work without module StreamingFile (from LocalFS). And Hallelujah! it solved our problem. However, why Zope is not able to cope with filestream_iterator anymore? What happened here since we only switched zope to apache?

I would like to have a ZPT showing images and links for files that are not within Zope filesystem, indeed they are in my local filesystem (they are created by an Unix program btw). So I am looking for something that may import my local folder and/or the files inside to Zope space where a ZPT can work with. For the moment, I would be more insterested in a external method or similar rather than LocalFS or any other product that I have to install in my zope server. Any commentary or advice would be very welcome.

[Zope] Dictionary in ZPT
Dears,
I am looking for help.
I want to pass, when submitting a FORM from a page template, dictionary.
I started with that:
tal:define=global count python: 0; global data python: {}
...
and I would like to do something like:
tal:define=global data['jname'] python: jname
or
tal:define=global null python: data['jname']=jname
But I get only error.
Is there a way of creating and increasing a dict inside Zope template page?
Many thanks in advance.
Cheers,
Alan

[Zope] passing *args to external method
Hi List! I've been trying without success to pass from a form in ZPT to an external method an undefined list of parameters (*args). An example: def external_method(var_fix,*args): return 'Vals',var_fix,args ... file _sub_html_: FORM ACTION=external_method METHOD=POST ENCTYPE=multipart/form-data input type=text name=var_fix value= input type=hidden name=arg1 value=test1 input type=hidden name=arg2 value=test2 INPUT TYPE=SUBMIT VALUE=Submit /FORM returns typed value for var_fix and () for args. However, if I do: def external_method(var_fix,arg1,arg2,*args): return Vals,var_fix,arg1,arg2,args it returns values of arg1 and arg2. But my problem is that the number args cannot be fixed since such arguments depends on other page. I hope one can understand it. And I'd appreciate very much any attention. Many thanks in advance.

[Zope] Killing children process
Hi List! Maybe it is more a question about python, but here it goes... I have an application in Zope which spawns a process (1) in background, a python program by the way. I monitor the process (1) via the PID returned. Embedded in (1), it uses os.system to run an application (2) which does the real job. (2) is a bash script with several embedded programs. However, sometimes I need to kill (1) (os.kill), and I hopped when killing (1), (2) and any of its children should be killed as well. But it does not happen; system (PID 1) inherit (2). I know if I were able to keep a list of any children and grandchildren process I could kill all of them smoothly, however for such a list I have no idea of doing it but: a)- doing a program to track them via unix command 'ps' output (maybe not reliable); b)- changing the code of the 3rd party programs (not really a good idea at all). All interaction are done via portal made in Zope. So, if someone could give any idea of how tackle with this problem, mainly avoiding a) and b), I would appreciate a lot. To simplify, I would like to know if python is able to kill a process and its 'family' without much hassle, and if so, how? Many thanks in advance.

Exactly.
Something like:
REQUEST.RESPONSE.setHeader('Content-Type', 'application/zip-compressed')
(uhm, not sure of the right spelling)
And return the file object, not its contents. The publisher takes
care of sending it on chunks if needed.

You might be interested have the original page under the original URL.
So a redirection is fine.
e.g. return self.zpt_or_whatever_template()
Or do all the form work in a python script anyway, which calls
the external method when everything looks ok and returns
with the template as above.
THis also work...depends on your usecase and requirements

It seems something's not properly clearing down the connection to release the thread. I doubt that this is the case. The IO, including the closing of the connection, is handled by the ZServer thread. This is a single thread. You would immediately observe should it block (Zope would be irresponsive). This *is* exactly the behaviour I'm observing. When the connection is closed, the Zope worker thread has already been released. By the way, their number is fixed (and usually small). Unfortunately, the server is out of threads and I can't use DeadlockDebugger to see what exactly Z2 thinks each thread is doing. As these threads have not completed, there's no access log entry, and the other socket terminal has obviously closed, meaning I can't chase the issue down from the other end either. I've upgraded a lot of software, and this issue is present on 2.8.6 as well. I'm confident this issue is with Zope (or more likely, a badly behaving product) - it manifests with httpd-2.0.54, and httpd-2.2.0-5.1.2 (both forked and worker implementations). Any ideas on how to track it down??

[Zope-dev] Python2.4 Security Audit ETA???
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, Aeons ago someone promised that said Zope security audit of Python 2.4 was scheduled for October. I've not yet seen any happy announcements that Zope is now 2.4 compliant, and do want to highlight the importance of achieving this goal. Python2.4 has been out for almost a year now, and it's fairly ubiquitous. There've been many statements made on this list about people quite happily running their Zope's - contrary to white hat advice. With the major distro's, Python is entrenched in their installer and gui processes and *all* packaging is focused around a single python (2.4 for everyone excepting our BastionLinux). In reality it is infeasible to support a second version of Python for Z2. Many modules have SWIG bindings (while core Z2 doesn't require much of this, a number of products do), requiring multiple package versions - build systems cannot cope with this scenario without massive spec customisations (which is all pointless given the window of this requirement - and of course that we've all actually learnt something for python2.5, python2.6 ) We are getting an increasing number of people attempting to load incompatible packages. It is not possible to downgrade python. Most of userland is not competent to get a secondary python2.3 installation running - especially when packages such as python-ldap are simply not available for their old python and new ldap etc etc which all requires custom package builds. We are also stuck in a time-warp actually having to back-port a large proportion of recent linux packages because we'd like to make new features available, increasing costs and testing requirements. It is also no longer possible for customers to subscribe to just a single channel because our core is substantially different to their chosen vendor's installation, and packages will be installed into meaningless python paths etc. Can someone please give me an ETA on this, so I can decide if and how to support zope in light of other pressing linux requirements for our distro.

Thanks.
This is really contorted. Why do you use URL2 and URL3?
To extract just the id of the image being viewed. The relative path
from the template that presents the image to the image being presented
will always match that pattern.
Is imgObj not just 'here' anyway?
Not in a manner I could easily work with, view is a folder containing
index_html (the page template in question), and a handful of other
page templates and scripts -- all of which are specific actions a user
may wish to perform on a single image -- rather than on a whole album.
Given the scenario I've outlined, do you have another suggestion?
I agree this isn't aesthetically pleasing, but to me it was quite intuitive.
What is the page template where this code comes from called?
/view/index_html
Why do you do a global define?
Because I'm godless.
Why two define statements instead of just one?
So as to not post a massively long line of code to the list that would
be even more spaghetti like. If it makes you feel any better the
actual code is more in the form:
div tal:define=long_line here
!-- code that works on imgObj properties, --
/div
The question I was trying to answer wasn't about some coding style
issue, but rather about how to convert a string path to an object at
run-time. I included the URL manipulation as an illustration of when
I had to use the path method.

Re: [Zope] Render a string as tal
Hi,
I'm not sure I entirely understand the goal here either, but you may
want to look into the path method.
Here's what I recently had to use it for.
I'm building a little photo album application for my sister, it
supports nested albums. I had a page template called view I was using
as a method, but wanted to logically group the actions specific to a
single image into a folder. So, I have a folder called view. When an
image is viewed the URL looks like
/some_album/some_pic.jpg/view/?display=large
If I want to do operations or locate properties on some_pic.jpg I
extract that part of the URL, and then pass it to the path function.
The code looks like this:
span tal:define=imgName python:request['URL2'][len(request['URL3']+1:]
span tal:define=global imgObj python:path('here/'+imgName)/span
/span
HTH,
Alan

We have one overriding objective in that we're very interested in reducing the window between core releases and third party developers making new releases both now and into the future. To this end, we've set up a development channel, synonymous with Rawhide for those familiar with Redhat/Fedora release management practices. Using yum or up2date, you can access this channel at https://linux.last-bastion.net/RPC2/up2date/development to transparently upgrade to the latest core. We will be producing regular releases of things Zope and Plone into the future here. At this stage, you do need to create an account on the portal as you need to be Authenticated to download. The Zope2.8/Plone2.1 packages happily sit alongside older installations. If you're an author of anything on https://linux.last-bastion.net/RPC2/up2date/plope, we're particularly keen upon getting you involved. If you've a Plope product you'd like to get put on this channel, then please do feel free to contact us. We're hoping to grow the list of successfully migrated packages as quickly as possible.

[Zope-dev] CMF TypesTool breaks id
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
I'm astounded that nobody has come across this before, but the
CMFCore.TypesTool.constructContent() function is supposed to return the
object id in the event that no RESPONSE is passed in - at least
according to CMFPlone.PloneFolder.invokeFactory().
Presently, it in fact returns nothing - breaking this implicit contract.
This has the unfortunate effect of *NOT* allowing you to generate your
own object id within your object construction function (we have a number
of requirements where external systems expect to see id's of particular
formats and I don't want to depend upon/pollute the generateId script
with specific meta_type requirements).
Plone's createObject script can't find this newly constructed object as
it's id isn't that generated by the generateId script and fails trying
to do a getTypeInfo() call on a None object.
I'm posting the patch here because in my mind this *IS* a very important
patch and I find the release schedule for CMF{Core,Default} inextricable ;)

[Zope-dev] Parrot
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Parrot 0.1.2 was released a couple of weeks ago. According to the release notes, there's now better python support, separated into dynaclasses. Unfortunately, I haven't really managed to keep up with the Parrot project, but I think it quite possibly represents the strategic future of Zope. An obvious benefit is the genuine concurrency it offers over GIL on SMP hardware. Anyone running an enterprise Zope or Plone installation would desire to take advantage of this. I know a year or so ago, someone received a pie in the face at a conference because Parrot still wasn't as fast as the native Python interpreter, but maybe this too has changed with this release. I'm very interested to know if anyone is investigating Parrot.

[Zope-dev] root ZServer

Similarly, I'd now expect issues if I chose to attach a Z2 to a low port.

[Zope-dev] FS PageTemplates and XML generation issues
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hi,
I have some PT skins I'm using to generate XML responses and am getting
some strange behaviour. I'm not sure if its because I misunderstand
something, there are bugs, or the API could be made more useful.
I will focus this discussion around the following ZPT:
?xml version=1.0 encoding=UTF-8?
repomd xmlns=http://linux.duke.edu/metadata/repo;
~ data type=other tal:repeat=source here/objectValues
tal:attributes=type source/meta_type
~location href= tal:attributes=href string:repodata/${source/id}/
~checksum type=sha tal:content=source/checksum/
~timestamp tal:content=source/timestamp/
~open-checksum type=sha tal:content=source/open_checksum/
~ /data
/repomd
What is happening with this is that it's not doing any TAL rendering at
all and just returning this 'raw' xml. However, if I customise my skin
and assure the content-type is text/html, then it indeed renders this 'xml'.
I have experimented with the xmlns on this to no avail. Besides, it
surely must be implicit in the choice of making this a FSPT, that I am
anticipating TAL/METAL rendering, and that any non-(ME)TAL tags in the
raw text are to be passed thru to the client...
I am also concerned that the FSPT code has implicitly assumed that the
content type is text/xml. While I'd prefer this to be the type, at this
stage, this choice does not work ...
I would however have thought that in lieu of an explicit statement, any
FSPT would be of type text/html...
This brings me to my other question: how do I set the content-type on
an FSPT?? It would seem that content-type=xxx in the [default] section
of the .metadata file is ignored.
I'd someone to comment upon my observations before investigating further.
Alan

No, I had a look and there's a strange test with a FSPT which explicitly
sets the REQUEST content-type. There's no test which checks this from a
.metadata file. There is a test which checks the title in a .properties
file.
I extended these tests (test_DirectoryView.py) and indeed setting
content_type as a property does pass the test. I also added a .metadata
test and it actually does pass this test too, although .metadata and
.properties files do appear mutually exclusive.
I've attached the patch of these tests if you want to apply it.
So, now I can't explain why my real-world .metadata content_type is
being ignored!

[Zope-dev] Re: Zope and Python 2.4
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 The reason I asked this question is because clients I talk to in the enterprise space are almost all exclusively RH9/RHEL clients, and many have major reservations about installing anything non-RH 'approved' as they feel they have some security assurances using this, and certainly RH are reasonable sincere with their efforts here. If ZC say Zope is approved and test with version X of Python, then this too has some weight in their minds. We have our own distro and stability within the flux of Zope, Plone and a large number of enterprise-targeted products is probably the major sales pitch. However, having to fork off the main Fedora branch in regard to Python dependencies (which directly affect Anaconda, up2date, GTK, and most of the desktop applets) has major implications for how we maintain our distro. So, I ask again, what is the official view on Python 2.4, and if there's a roadmap as to when it will become blessed.

[Zope-dev] Announce: FSPerlScript
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hi,
This patch is against CMF-1.4.7, although one could equally argue it
better suited elsewhere - there appear to me to be minor uncomfortable
dependencies regardless of where it sits (unless it's made an
independent product - which seems a little unwarranted given it's
simplicity).
This patch includes the following:
~ FSPerlScript.py
~ images/fspl.gif(needs an artiste to draw a padlock!)
~ tests/test_FSPerlScript.py
~ tests/fake_skins/fake_skin/test1.pl
~ tests/fake_skins/fake_skin/test2.pl
~ __init__.py (FSPerlScript registration)
Unfortunately, FSPerlScript is not quite as useful as I'd anticipated,
given that the 'use' statement is a restricted opcode.
I am more than willing to discuss with any interested party(s) how we
may implement a security mechanism whereby we can specify 'safe' Perl
modules, much as we do with the Python modules_allow stuff.
Cheers, Alan

Ok, I now more fully understand the subtlety of this explanation.
What happened here is that in cgi.py's FieldStorage class, since this is
a GET request, it completely ignores the CONTENT_TYPE environment and
sets the content-type header to x-www-form-urlencoded.
According to Dave Winer's spec at http://www.xmlrpc.com/spec, XML-RPC is
supposed to be HTTP-POST based, where this issue is fully resolved.
I have implemented this GET 'Extension' with this patch.
I appreciate that supporting 'unofficial' extensions to protocols is not
something we want to encourage, but is there any chance of getting this
patch into zope core (ever)?

[Zope-dev] serving BLOBs
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, I know serving large BLOBs is rather frowned up using Z2, but I have a requirement to use the zope security machinery prior to serving a blob circa 500Mb. I thought I'd just wrap it in an ExternalFile and it would simply stream to the client. In fact I was even anticipating taking advantage of chunked transfer encoding for HTTP1.1 clients. However, I'm getting out of memory exceptions thrown by the server. This would indicate that no intermediate buffer flushing is occuring at all! What am I missing?

[Zope-dev] xml-rpc changes between 2.7.0 and 2.7.3 ??
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, I had a client that used to work on 2.7.0, and now doesn't on 2.7.3. The problem would appear to be that it's not substituting the xmlrpc.Response class for a GET request on a text/xml content type and therefore just delegating to the str() function instead of wrapping it in the xml-rpc xml response tags. I'm a little confused about this, as this only appears to happen in HTTPRequest::processInputs which didn't seem to be invoked for my xml-rpc call anyway ... tcpdump follows for the sceptics ... j.. 08:05:04.901469 IP mistress.balclutha.org.34257 mistress.balclutha.org.zope: P 1:456(455) ack 1 win 32767 nop,nop,timestamp 225097763 225097723 [EMAIL PROTECTED]@.)..W.x... j..GET /last-bastion.net/junk/rpm/RPC2/$RHN/mail/listPackages/1 HTTP/1.1 Host: localhost:8080 Accept-Encoding: identity x-client-version: 1 x-transport-info: Extended Capabilities Transport (C) Red Hat, Inc (version 1.40) x-up2date-version: user-agent: rhn.rpclib.py/$Revision: 1.40 $ x-rhn-transport-capability: follow-redirects=1 x-rhn-auth-channels: ['mail', '1'] content-type: text/xml x-info: RPC Processor (C) Red Hat, Inc (version 1.44) 08:05:04.901498 IP mistress.balclutha.org.zope mistress.balclutha.org.34257: . ack 456 win 32767 nop,nop,timestamp 225097763 225097763 [EMAIL PROTECTED]@.x.W. j.# 08:05:04.910507 IP mistress.balclutha.org.zope mistress.balclutha.org.34257: P 1:871(870) ack 456 win 32767 nop,nop,timestamp 225097772 225097763 [EMAIL PROTECTED]@..x.W. j.#HTTP/1.1 200 OK Server: Zope/(Zope 2.7.3b1-0, python 2.3.3, linux2) ZServer/1.1 Plone/2.0.4 Date: Mon, 11 Oct 2004 22:05:04 GMT Content-Length: 690 Content-Type: text/plain [['EnchantMail', '2.0.0', '4', '', 'i386', '121577', 'mail'], ['courier', '0.47', '1', '', 'i386', '4172641', 'mail'], ['courier-imapd', '0.47', '1', '', 'i386', '400894', 'mail'], ['courier-ldap', '0.47', '1', '', 'i386', '109401', 'mail'], ['courier-maildrop', '0.47', '1', '', 'i386', '1178663', 'mail'], ['courier-maildrop-wrapper', '0.47', '1', '', 'i386', '0', 'mail'], ['courier-mlm', '0.47', '1', '', 'i386', '250756', 'mail'], ['courier-pop3d', '0.47', '1', '', 'i386', '115327', 'mail'], ['courier-smtpauth', '0.47', '1', '', 'i386', '257063', 'mail'], ['courier-webadmin', '0.47', '1', '', ~ 'i386', '22047', 'mail'], ['courier-webmail', '0.47', '1', '', 'i386', '970798', 'mail']]08:05:04.910534 IP mistress.balclutha.org.34257 mistress.balclutha.org.zope: . ack 871 win 32767 nop,nop,timestamp 225097772 225097772 [EMAIL PROTECTED]@.+..W...Y. -BEGIN PGP SIGNATURE- Version: GnuPG v1.2.4 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFBawY2CfroLk4EZpkRAmtFAKDVLmORsmw6LacIUizLNn111t1J+wCffq7w 3Pbm2RrCvIFKlkxuUg1BDaA= =MbC0 -END PGP SIGNATURE- ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
Re: Re: [Zope-dev] xml-rpc changes between 2.7.0 and 2.7.3= ??
According to the CHANGES.txt there were no changes to XMLRPC. xmlrpc.py is not faulty, it's just that an HTTPResponse object is assigned to the text/xml content type rather than the correct xmlrpc.Request :( ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
[Zope-dev] Re: [Plone-developers] Re: Five and 2.9
Alan, does that address your concerns? Just understand that the Five approach is still being developed, so there's nothing to adopt yet. :) But I certainly encourage folks to participate and help Martijn figure out what the approach should be. Raphael, I think its great that Jim responded. Now we (collectively) need to get some usage out of Five. Jim, Thanks for explaining ZC's position re: FrankenZope or backporting CA into Zope2. One of the big questions that I believe is open is how to use more of zope.app in Zope 2 - specifically Schema/Widgets. I heard that Zope Corp. is using this in some projects. So - I asked if people to do some CMF/Plone implementation of Views in certain aspects. I am up for creating a Supplement to Plone to bolts on some of the technologies and uses it. Maybe specifically using it for doing in-place versioning. I urge the communities to use Plone or maybe a fork of it (or the CMF) to be a playground. Like Idle forked to land some major features for Python. Then it can be integrated back into subsequent projects. -- Alan Runyan Enfold Systems, LLC. - Principal Plone/Zope Training, Products, and Consulting http://www.enfoldsystems.com/ p. +1.713.942.2377 f. +1.832.201.8856 ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
[Zope-dev] XML-RPC incorrect 404 return code
Hi, I'm doing some stuff using Zope as an XML-RPC server, and have come across a rather interesting bug. If the method doesn't exist on the Zope server, Zope returns an xmlrpclib.Fault with a faultCode= -1. This completely trips out my XML-RPC client which was rather expecting an xmlrpclib.ProtocolError. Does anybody have a strong opinion on sorting out ZPublisher.xmlrpc.py to to do a little more than it's present rather lame error handling??

[Zope-dev] ZScheduler
Hi, Following on from work started at the Zope3 Sprint in Melbourne, I've got a release candidate for a Zope scheduler. This is available from http://www.last-bastion.net/ZScheduler, where although the documentation is a little light, I've taken efforts to write online helps, although it's all reasonably intuitive. This is an attempt at delivering a definitive solution to this issue, and I'm keen to get community feedback as to what additionally is required. Since I personally am much more familiar with Z2 than Z3, there's only a Z2 release candidate at this stage - once the prescribed functionality is agreed I will produce a Z3 port (well - if I can't find any volunteer(s) ;) ...). If anybody associated with the recently released ZopeScheduler product (or any other competing product) is listening to this list, could they please make an effort to coordinate with me about the longer-term incantation of both as it's a little pointless not having a single answer to this utility.
