[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? Any help would truly delight me Roché ___ 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 )
[Zope-dev] 'Subclassing' another product
I think I read somewhere that it was, from version 2.2 of Zope, possible to 'subclass' products. Is this just somebody janking my chain, or is it actually possible?

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: """ paramsself/params 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] 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] Performance enhancements, ZCatalog
ZCatalog enthusiasts, I just upgraded our zope installation from 2.1.6 to 2.2.4, and the ZCatalog performance is aweful. Can someone remind me what the command for speeding up python on a dual processor machine is? python -T? I'm looking for any way to speed this up. I have a text index with 47,000 objects and a search takes about 15-18 seconds, hardly what we were used to. It used to be 2 second tops. My company is being shopped around and if we get bought I want to convince the new company that Zope and python and Linux are the way to go. I need all the help I can get.

[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

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:
import Products.PythonMethod.Guarded
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'
def makeFunction(self, compile=0):
from Products.PythonMethod.Guarded import GuardedBlock, safefuncs, theGuard
if compile:
self._checkCBlock(GuardedBlock)
if self.errors:
raise "Python Method Error", string.join(self.errors, '\n')
return self._newfun(compile, {'$guard': theGuard},
__builtins__=mysafebin, _=safefuncs)
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,
constructors=(CVSFolder.manage_addCVSFolderForm,
CVSFolder.manage_addCVSFolder),
icon='fish.gif',
)
context.registerBaseClass(ZCVSMixin.ZCVSMixin)
does that help?
take care,
-steve
