[Zope-dev] External method
This is not a strictly zope related question but it is zopeish :) In an external method I need to call an executable and capture the output it generates. This executable however needs to connect to a running X Server. I used the popen2 command but it returns with the obvious error : "theprogram : cannot connect to X Server". So how does one tell a program to attach to a X server?

[Zope-dev] Loginmanager and local roles
Using LoginManager, I can't seem to map local roles to users that are stored in LoginManager instances. I.e.: if this acl_users is a LoginManager /a/b/c/acl_users then any object in /a/b/c/d will not show any of the users stored in the nearest acl_users object in the local roles management menu..

Re: [Zope-dev] Loginmanager and local roles
[Morten W. Petersen] | Any suggestions? Found the problem. There needs to be a method called user_names in the acl_users folder, which returns all the user ids: """ self user_ids = self.UserSource.getPersistentItemIDs() user_ids2 = [] for id in user_ids: user_ids2.append(id) return user_ids2 """ (Can't understand why I had to use an additional list though).

RE: [Zope-dev] SQLAlias Memory Leak?
Hi guys - I've attached a patched RDB.py that you should
be able to drop into lib/python/Shared/DC/ZRDB/ that (for
now) reverts to an older (non-SQLAlias) implementation
that should solve the immediate problem.
If you folks can try this out and let me know if the
problem goes away, I'll check this in for 2.2.5 until
we can debug the root of the problem with SQLAlias.
Thanks!

Re: [Zope-dev] regex (or re) modules
Because both are quite capable of crashing a thread (maybe the whole thing), with poorly written regex expressions. Creating infinate loops is easier than you think, esp if your regex requires backtracking to "solve". Perhaps there should be a simplified regex engine available, that I don't know.

[Zope-dev] Re: [Zope] [BUG] Background processes interfere with Zope's HTTP responses
Hi Deiter,
Hmm.. I just tried this with my highly experimental product
(LocalProc 0.0.1) and I didn't observe the same effect that you did
behind my Proxy Server. (I normally run with Rewrite... but when I got
your note I tried ProxyPass and it worked on the first try.)
(Good howto Anser! http://www.zope.org/Members/anser/apache_zserver/)
Anyway... I ran 'sleep 20' as my local process (I checked the
'background' button on my product) and the web page returned
immediately, but the process ran on in the background as I wished. The
main difference I see between what you are doing and what I do.. is
that I redirect stdout and stderr so that my subprocess has no open
files shared with the parent process.. anyway.. you might try this to
see if it suits your needs. Lightly tested on FreeBSD only.. but any
unix should work the same...

[Zope] [Zope-dev] [BUG] Background processes interfere with Zope's HTTP responses
Today was again a hard Zope day.
Did you ever hear, that usually (i.e. if you do not do special
things) Zope renders a complete page before it starts
sending the result back to the client.
This implies that you should never see only half of a page.
I heard it and I saw the code that does it.
Therefore, I was convinced that this were really the case.
Then our client phoned:
He visits a page that allows him to generate a
newsletter. When he presses the "generate newsletter button",
a result page is build that tells him that the newsletter
is being generated and send is a few minutes.
He reported, that this response page is build only
half, then stops, to be completed only half a minute later,
at the same time when the newsletter arrives.
The effect is reproducible. If newsletter generation
takes longer, he must wait longer for the page to complete.
He is convinced that we generate the newsletter synchronously
and let him wait until the generation is complete.
And he is angry.
I know, that the newsletter is generated in a background
process, started in an external method with:
os.system("gen_newsletter &")
I try to reproduce the behaviour in our test environment
and fail. I do not have to wait, until the newsletter
generation finished. Then, I use the official service
URL and see, I observe the same behaviour.
The difference: in the test environment, the browser
connects directly to ZServer; with the official
URL, it connects via a proxy.
Puzzling!
What happened?
The background process inherits Zope's open file descriptors.
Among them are all currently open HTTP request sockets.
The process keeps these sockets open until it finishes.
There are two HTTP modes:
1. single request mode
a new TCP connection is created for each HTTP request,
the request is completed, when the TCP connection
is closed.
2. multi request mode
several requests share a single TCP connection.
The "Content-Length" HTTP header allows
client and server to determine the request boundaries.
That means: when a client uses the multi request mode,
everything is fine. Clients, however, that use
the single request mode wait until their connection
is closed and can observe serious delays.
These delays may be very difficult to explain, as
the background process not only delays its own
request but may delay arbitrary other requests
that happen to be served at the same time.
How to fix the problem:
There should be a (file) control "CloseOnExec", that tells
Unix to automatically close the file like object upon
an exec.
ZServer should probably use it on each of its sockets.
I can not see a serious application that should have
direct access to ZServer's HTTP request socket.
I will soon file a bug report into the Collector.
Dieter

[Zope-dev] A groupware package for zope
For the last couple of months I've been working on a groupware package for Zope, named ZopeGUM. It has reached version 0.1.63 now, and it's in steady progress. All the planned components, like messenger, address book, calendar, todos, etc. are there and working now; though it's definently not ready for a production enviroment yet. Anyways, just wanted to let you all know. (And yes, I do appreciate feedback. =) -Morten ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Some older browsers have a limit to the amount of data they send in a request, usually around 64k. On the other hand, you may want to examine what is actually in the REQUEST object. You can view the contents by including the REQUEST object in your page: -- Martijn Pieters | Software Engineer mailto:[EMAIL PROTECTED] | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ - ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] 'Subclassing' another product
Hi Morten,
There are two ways to subclass products. You can use straightforward
Python subclassing:
e.g.,In your custom Product.. here is an example from Zwiff:

>
> from Globals import HTMLFile, MessageDialog
> from App import Common
>
> manage_addZwiffForm = HTMLFile('addForm',globals())
>
> def manage_addZwiff(self, id, title, params, body, REQUEST=None):
> """Add A Zwiff to a folder just like PythonMethod..
> """
> it = Zwiff(id, title, params, body)
> self._setObject(id, it)
> return self.manage_main(self, REQUEST)
>
> def handleMovieOutput(movie, RESPONSE):
>
> fname = tempfile.mktemp()
>
> movie.save(fname)
>
> f = open(fname)
> s = f.read()
> f.close()
>
> RESPONSE.setHeader('Content-type', 'application/x-shockwave-flash')
>
> os.remove(fname)
>
> return s
>
> class Zwiff (Products.PythonMethod.PythonMethod.PythonMethod ):

> meta_type = 'Zwiff'

So the class Zwiff is a subclass of PythonMethod. Look at Zwiff for the full
source: http://www.zope.org/Members/sspickle/Zwiff
Or you can create a ZClass that subclasses from a 'base class'. To do
this you've got to register the base class with the ZClass machinery
(e.g., here is the code for ZCVSMixin that does this ZCVSMixin
is a base class... CVSFolder is a full blown product that happens
to be a subclass of ZCVSMixin... )
>
>
> import ZCVSMixin
> import CVSFolder
>
> __doc__ = ZCVSMixin.__doc__
> __version__ = ZCVSMixin.__version__
>
> def initialize(context):
> context.registerClass(
> CVSFolder.CVSFolder,

> CVSFolder.manage_addCVSFolder),
> icon='fish.gif',
> )
> context.registerBaseClass(ZCVSMixin.ZCVSMixin)
>
does that help?
take care,
