Re: [Zope] External Method in Zope
If you absolutely have to, look at Paramiko a python ssh/sftp library which is easy to use but as mentioned already there are critical security issues. with paramiko you don't have to directly edit the files but within an ssh connection run the commands needed that actually make the changes. You may have to put in time.sleep(x) commands to give the response time to come back, where x is an integer.

I was hoping that I could get the path where 'Extensions' is because I work with several zope installations in several platforms and I would like to make my module independent of a variable inside its code that should be manually adjusted for every situation. And yes, I am aware about adding the path only once (that's why there's a 'if') and then I avoid recursive insertions.

It does not look like a Zope (version) issue:
The import in an External Method is a pure Python import -- without
any restrictions or additional magic.
Therefore, if sys.path is still correct inside the External Method,
all modules/packages reachable by sys.path should be importable.
I would check sys.path.

Re: [Zope] External Method = Slow; Shell Script = Fast
ZopeProfiler seems to come with no instructions to install. Can you advise? I haven't installed it for years, but i seem to remember that it installed just like a normal product (ie. install in the Products directory, restart zope, it shows up automagically - in linux that is, i don't do windows). Wasn't there a README when you unpacked the tarball? Maybe someone else on the list has more recent experience... AFAIK profiling is integrated into Zope right now. Take a look at zope.conf and you'll find proper section. Although I'm not sure how it works. I've used ZopeProfiler product. To install ZopeProfiler product you have to copy it to Products/ folder of your zope instance, restart your Zope and go to ControlPanel in ZMI. You should see new link there: Zope Profiler.

Basically it takes two XML files - one defines constraints, the other variables - and the script finds a solution using the variables that satisfies the constraints. At the command line (or executed via an external method that calls a shell script) execution is 2 seconds. As an external method execution is 15-20 seconds with the same input. Can anyone offer tips or strategies to improve performance? It would be obnoxious to have to encode objects for passing to a shell script. You should use something like ZopeProfiler or CallProfiler to find out where the time is being spent.

Re: [Zope] External Method Working Directory?
Products?? That is odd. I thought it was the var/ directory or at least the zope instance home directory. From the External method you should have access to INSTANCE_HOME and SOFTWARE_HOME. Try if these are what you want. I doubt that you'll find your Extensions/ dir in any of them so you might have do something like: import os return os.path.join(INSTANCE_HOME, 'Extensions') 2005/9/28, jwithers [EMAIL PROTECTED]: Folks, I have an external method that at this point is made up of nothing but os.getcwd() and lives in my Extensions directory.

Re: [Zope] External Method Working Directory?
jwithers, a) Is your os.getcwd() (in /Extensions) called from a Product (in /Products?) Otherwise I have not idea b) Regarding temporary files .. I've used stuff like ... import tempfile tmpFile2 = tempfile.mktemp() theFile=open( tmpFile2,'rb') result = theFile.read() theFile.close() os.remove(tmpFile2) I think this may depreciated but do a google on python tempfile and you can use the updated modules if they apply to your issue.

Re: [Zope] External method and stdout
Andreas Pauley wrote:
For some reason you have to "return" everything that should be available
to zope. You can return a sequence and loop through it with DTML or you
can build a variable with everything you want to display and then return
the variable.
I have no idea why this is so, and why you can't just the print
statement as an equivalent to dtml-var.
There is probably elegant ways of replacing DTML with external methods
or Python Methods, I was just unable to find documentation and examples
on it until now. Can anyone help with this?
Regards,
Andreas.
there are a couple of ways. first zope's publishing objects. if your
publishing a dtml method object than the semantics of it require that
values be inserted into the template/page thats being returned to the
user. you can also publish an external method or a python module
directly(indeed Zope is just a published python module). but sticking to
zope external methods, an example, if you had
def myhello_world(self, REQUEST):
page = " welcome to %s corner of my hello world
"%self.getParentNode().id
and just browse directly to the external method. its important to keep
in mind that stdout isn't connected to the client. the client is
connected to medusa/ZServer, which gives a channel to ZPublisher to
publish data that will be returned to the client. this mainly applies to
fs code, i'm not totally sure about the semantics of web python
methods. i know this probably goes a bit further down the rabbit hole
than you might be interested in going. if you want to know some more of
the details.
check out the medusa docs at
http://www.nightmare.com/medusa
and the ZPublisher docs under the Documentation Sec. of Zope.org.
These are dated but they give a understanding of the interaction between
medusa's asynch interfaces and zope.
and of course the source code.
you could also use document templates directly from python
def new_world_order(self, REQUEST):
from DocumentTemplate import HTML
my_sites = [('My homepage','http://homepage'),
('my favorite bookstore','http://amazon.com')
, ... etc]
page_to_return = """
html
body
ul
dtml-in sites
lia href="dtml-var sequence-item"dtml-var sequence-key/a/li
/dtml-in
/ul
/body
/html
"""
return HTML(my_sites)(sites=my_sites)
or evaluate a dtml file on the file system using HTMLFILE
see the DocumentTemplate directory for source and more examples
D.Templates also give you a pretty good separation of app. logic and
presentation. Doing straight python insertion in a page is not the Zope
Way. if you're interested in this type of thing, you might want to check
out some other python projects like mod_snake (apache),
pywx.sourceforge.net (aolserver), or webware. I'll think you find the
benefits of doing it through DTML offer you a lot more benefits in terms
on maintainbility and site management.
Cheers
