[Zope] external method
I have the following external method to back up a postgres database,
using the following software versions.
Zope Version
(Zope 2.9.0, python 2.4.2, win32)
Python Version
2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)]
System Platform
win32
Zope is running as user scholarpack who is an administrator on win
server 2008.
/
import subprocess
def backup():
try:
p=subprocess.Popen("c:/scholarpack/postgres/bin/pg_dump
scholarpack",shell=True,stdout=subprocess.PIPE)
data=p.communicate()[0]
f=open('c:/scholarpack/ancillary/scholarpack.sql','w')
w=f.write(data)
f.close()
except OSError:
print "There was a problem opening the file for writing"
/When I run this through Zope I get an empty file. There are no errors
reported. However, if I use the same python that is running zope in an
interactive shell and run these commands then it works as expected.
Can anyone spot what I am obviously missing?
Regards
Garry

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.

Formerly, the "ExternalMethod" documentation suggested to put such modules into "/Shared//...". Nowadays (since Zope 2.7, I think), "/lib/python" is a better place (with any structure you would like to use). This folder is put on "PYTHONPATH" automatically.

You can easily check what's in your sys.path by having your external method return it.

[Zope] External Method unable to run Java jar executable using os.system()
Hi,
I'm trying to run an external method that has a line that runs an os.system
command to execute a Java .jar executable that simply outputs a text file as
well as prints out a string.
I've saved the python script as well as the Java .jar executable in my
Extensions folder:
/var/lib/zope2.8/instance/plone-site/Extensions/
Here is my Python script:
def runYahooSearch2(self):
import os
homedir = os.getcwd()
# on my machine homedir is /var/lib/zope2.8/instance/plone-site
command = "java -jar "+ homedir + "/Extensions/test.jar"
whatisread = os.popen(command).read()
print whatisread
This external method is triggered in my DTML code. I've created other external
methods before so i know i've done it right.. but the os.system() command for
java -jar just doesn't seem to work. I've tried to use other commands such as:
os.popen("ls") and it works perfectly
Its just this java -jar which does not execute at all... I know it doesn't
execute at all cos it doesn't output a file or print the string. If i manually
type out into the terminal :
java -jar /var/lib/zope2.8/instance/plone-site/Extensions/test.jar
it works perfectly
But using the external method given above just gives me a blank output.
I've also tried popen2:
from popen2 import popen2
outputTGT, inputTGT = popen2(command)
print outputTGT.readline()
and still the jar is simply skipped and not executed.
Does anyone know whats the cause and cure for this problem?... Or anynone knows
any other method i can use instead of os.popen os.popen2 and os.system to run
this command line statement?... or any way i can catch the exception which is
being thrown when the java -jar is attempting to run ( if there is any in the
firt place) ?
Anything would be highly appreciated!... Kinda in a fix right now!...
Thanks in advance!
Cheers
Wan

[Zope] External Method and XML-PRC (Maybe a bug)
Hi,
Iam trying to use Zope as an App server (basically to provide an XML-RPC
interface) for a certain application .
I have a function called addFile in the External Method.
def ext_addfile(self):
ob=self.Files
ob.manage_addFile("hello","hello")
I created an external method call ext_addFile()
Now I write my client using xml-rpc lib
s=xmlrpclib.Server("")
s.ext_addFile()
And this adds a file to my directory. This freaked me out. Because i was
anonymous user and this shdnt happen. The next thing i did was create a
python script of the same structure and called it addFile()
ob=context.Files
ob.manage_addFile("hello","hello")
Now I run my client xml-rpc program
s=xmlrpclib.Server("")
s.addFile()
and its fiving me unauthorized as expected.
So basically i dont know why is this happening. Is this due to some
permission problems i have on the directory or External Methods, or
something which iam totally missing.

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".

I don't see any indication for a cPickle issue. *Trible* check that your
Zope instance use the system Python installationl. Check your file
permissions, check sys.path, check your $PYTHONPATH.

[Zope] External Method cPickle Import Module Error
Hi,
I have upgraded from Zope 2.8.5 to 2.9.4. This currently works in the
2.8.5 instance but not in the 2.9.4.
I have a Module Progress in /usr/lib/python2.4/site-packages/Progress
containing 4 files:
__init__.py __init__.pyc Progress.py Progress.pyc
Both instances have calls to neuro.py which includes:
from Progress import Progress
The External Method in both instances looks good. I even updated the
External Method by clicking the Save Changes button without
error in the new 294 instance.
But when I access it from the dtml-method it goes boom:
Traceback (innermost last):
Module ZPublisher.Publish, line 115, in publish
Module ZPublisher.mapply, line 88, in mapply
Module ZPublisher.Publish, line 41, in call_object
Module Products.ExternalMethod.ExternalMethod, line 134, in manage_edit
Module Products.ExternalMethod.ExternalMethod, line 141, in getFunction
Module App.Extensions, line 148, in getObject
- __traceback_info__: ('/var/lib/hip_294_251/Extensions/neuro.py',
'neuro')
Module /var/lib/hip_294_251/Extensions/neuro.py, line 299, in ?
Module /var/lib/hip_294_251/Extensions/neuro.py, line 9, in GetProgress
ImportError: No module named Progress
But Progress is in: /usr/lib/python2.4/site-packages/Progress !
If I just start python at the command line I can import Progress w/o
error. I'm guessing that it has something to do with how
cPickle is sandboxed by Zope, but I just don't get it.
Any guidance sincerely appreciated,
Sean

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.

Almost surely, "postgres" does not like the command your have generated.

I have no idea what's causing your problem, but this raises
red flags for me: if two people upload sources at the same time,
you'll have problems here. If you really really must read/write
files on the filesystem, either use locks or use python's
tempfile module.

Are you just using saxon for xslt processing? If so, IMO using an
external process for that is severe overkill. Get lxml and try
something like this:
from lxml import etree
style = etree.XSLT(etree.parse(some_file_object))
transformed = style.apply(source_data)
but again, this doesn't address your immediate problem :)

[Zope] external method strangeness
Can anyone explain what is happening here. I am using Saxon to transform
an xml file(source) using a stylesheet(style) the result is then written
to Postgres. The contents of source are uploaded in Zope and passed to
the external method as a string. When I run this external method:
import psycopg, string, re, subprocess
def scholarpack_xml_transform(source):
f=open('/opt/scholarpack/ancillary/source.xml','w')
f.write(source)
f.close
source= '/opt/scholarpack/ancillary/source.xml'
style='/opt/scholarpack/ancillary/style.xml'
source1=source.replace(''','`')
source2=source1.replace('NLPGaddress','BS7666address')
p=re.compile("\'")
source3=p.sub( '`' , source2)
r =
subprocess.Popen(['/opt/scholarpack/ancillary/jre/bin/java','-jar','./saxon.jar',source3,style],
stdout = subprocess.PIPE,cwd = '/opt/scholarpack/ancillary/')
r.wait()
transformed = r.stdout.read()
transformed1=transformed.replace(',)',')')
conn = psycopg.connect("dbname=scholarpack user=scholarpack")
curs = conn.cursor()
do=curs.execute(transformed1)
do
conn.commit()
conn.close
I get a programming error thrown from the conn.commit() line and the
method fails. However when I run the following script externally to Zope
after the Zope failure (so that source.xml exists) the DB write is
successful.
#!/opt/scholarpack/python/bin/python
import psycopg, string, re, subprocess
source='source.xml'
style='style.xml'
source1=source.replace(''','`')
source2=source1.replace('NLPGaddress','BS7666address')
p=re.compile("\'")
source3=p.sub( '`' , source2)
r =
subprocess.Popen(['/opt/scholarpack/ancillary/jre/bin/java','-jar','./saxon.jar',source3,style],
stdout = subprocess.PIPE,cwd = '/opt/scholarpack/ancillary/')
r.wait()
transformed = r.stdout.read()
transformed1=transformed.replace(',)',')')
conn = psycopg.connect("dbname=scholarpack user=scholarpack")
curs = conn.cursor()
do=curs.execute(transformed1)
do
conn.commit()
conn.close
Can anyone point me in the correct direction?

It provides however a builtin "reload" which you can use to explicitely reload a module. Be warned the "reload" is dangerous. Funny effects can happen.

Apparently, you have one of them installed. In general, it is a bad idea to change the current working directory in a multi-threaded application (such as Zope). An External Method does not have a specific working directory "when it is run". Because Zope must not modify the working directory, it cannot let it follow the "run of an External Method". The current working directory remains what it was.

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 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.

[Zope] External Method file generation Vs MSIE
Hi All, I have an external method that generates files - zip, pdf and xls. I would like the browser to present a file open/save dialog box and, depending on what the user clicks, open or save the file. Also, I want to be able to set the file name. Sounds simple enough and with most browsers setting the Content-type appropriately and the Content-Disposition to "attachment; filename="whatever"' works. I have not been able to get Internet Explorer to work properly though. Has anyone got this working? If so, how? Here is a full run down of the problem... I believe Internet Explorer uses a combination of the following to decide what to do with a file: o The Content-Type header. o The Content-Disposition header's value. o The Content-Disposition header's filename attribute's extension. o The extension of the external method. o The first part (200 bytes?) of the file contents. o The phase of the moon. (well, perhaps not, but it's starting to feel like it.) It then does one of the following: o Displays the file inline in the browser. o Displays the file open/save dialog. Clicking the save button saves the file. Clicking the open button launches the application that is associated with the file type IE has assumed the file to be but that application gives a file not found error. o Displays the file open/save dialog. Clicking on open or save displays another file open/save dialog. Clicking the save button again saves the file. Clicking the open button again launches the application that is associated with the file type IE has assumed the file to be but that application gives a file not found error. The filename of the file saved or the suggested filename when saving a file being viewed inline is sometimes the filename attribute in the content-disposition header and sometimes "external_method?query=string.ext". I have tried various combinations of the following: o Setting the Content-Type header to the file type, application/octet-stream, application/x-force-download, etc o Not setting the Content-Type header. o Setting the Content-Disposition header to inline, attachment and download with and without a filename attribute. o Not setting the Content-Disposition header. o Naming the external method filename.ext where ext is zip, pdf or xls as appropriate. o Hard coding the settings in the external method and not using a query string. Despite all this I have completely failed to get MSIE to behave in a sane manner and would greatly appreciate any advice anyone has on the matter.

[Zope] external method and security
Hello,
I've written an external method that I call through xml-rpc. It lets
me create files on the server from a stand-alone client application
that runs on the workstation of my users.
In testing it recently, I discovered that it will let me write files
to secured folders within my Zope system, even though I'm not yet
using the patch to xmlrpclib.py that supports authentication!
I'm running Zope 2.2.5 under redhat 7.0.
The external method is included below.
Any clues would be appreciated. Thanks in advance
Is it up to me to write my own security code when using an external
method?

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

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.

Re: [Zope] External method and stdout
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 . 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?

[Zope] External method and stdout
Hallo, that's the problem: I've made an external method which is working with lists and should return the result to Zope. The python code is working very well, but is sending everything to sys.stdout( I'm using the print-statement).How do I convince Zope to print the result on the html-page. Thanks.

In the first case, you can use "REQUEST=self.REQUEST" to get the REQUEST object. In the second case, you use REQUEST directly. "REQUEST.form" contains the form variables of the REQUEST.

[Zope] External Method not accepting CGI module
Dear All, I have this python module for uploading an image from a client to the server (which would be subsequently inserted into a MySQL database, which is still on the midst of being resolved). I''m trying to import this into Zope as an External MEthod. It's contents are as follows : import cgi form = cgi.FieldStorage() fileitem = form["userTABPIX1"] fname = tempfile.mktemp() fp=open(fname,'w') fp.write(fileitem.file.read()) fp.close() However, Zope generates this error : Zope has encountered an error while publishing this resource. Error Type : KeyError Error Value: userTABPIX1 Apparently, this piece of code is supposed to work. I grabbed it off the mailing list, and I've compared with the python references and tutorials. Is it because it's not meant to be used as an External MEthod? If so, can anybody suggest a way for me to upload files from the client to the server which will subsequently be inserted into a mySQL db? I posted another message in the archive earlier on which describes my previous attempts in inserting an image into the mySQL database from a form. Thanx, k.c.

After I posted, I did some more wild, random, send-up-a-prayer hacking and I think I discovered the problem. It appears that the name of the external method and the name of the module file must be the same. At least, I changed the name of the file to genhash.py and things worked. It could be that the file was called md5.py, and since there is a Python module called md5, the interpreter may have been getting confused. I don't know which. Can any one shed some light on that?

[Zope] External Method Difficulties
For background purposes, I need to write a python module that will generate an MD5 hash of a given string, and return the base 64 representation of that hash. The problem I am facing is getting my stub to work from my DTML document. What I have write now is a stub that takes no arguments and returns "Hello, World". When I click Try It from the management screen, it works fine, but I can't seem to make it work from the DTML doc. This is what Iv'e tried (I'm still pretty new so I'm making wild guesses :) This produces nothing. I think I read somewhere that dtml-call returns no data, so that might explain it. I could be wrong. This produces a KeyError. It seems like I've tried a couple of other manglings, but what they were escapes me for the moment. I'm not passing a parameter right now, cuz I wanted to simplify things once I found out it wasn't going to work like I expected it to. What am I doing wrong? Is there a better place to start than this list? I have the content manager's guide and the dtml reference, but I can't find anything helpful. The ID for the external method is md5 in case that helps. Thanks a lot! -- Jason Lee - Programmer/Analyst The Fox and the Grapes: I'm not sure what the point is here.
