Hi
I was given an exstremly useful answer to a problem that I had in
windows. I'm relativly new with python, but find it exstremly useful.
I'm creating a script to run test files and record output, the script
already works on win32 and I've made a telnet procedure which works
quite well when you want to do the testing on one of the many unix
boxes (but its very slow). What I want to do now is run the script on
a unix system, and later on, create a rsh function to run the tests on
different unix boxes which have not got python on them.
The following snippet of code is what I use on win32. just example
sets some env vars and executes an exe, collects and processes the
output. :
output, input = popen2("cmd.exe ")
# Sets the enviroment.
input.write("se t LI_DIR=value\n" )
input.write("se t LI_DIR_ALT=valu e\n")
input.write("se t LI_ARCH=value\n ")
input.write("se t LI_PRECISION=va lue\n")
input.write("se t LI_PERFORMANCE= value\n")
input.write("se t LI_LINKING=\n")
input.write("se t LI_ARCHFLAG=\n" )
input.write("se t LI\n")
# Writes commands to it.
input.write(f_m wtest_exe_str + " " + f_mwtest_args + " " +
os.path.dirname (f_testlwc_str) + " " + f_testlwc_str + "\n")
input.write("ex it\n")
while 1:
text = output.readline ()
if text:
process text line
else:
break:
The unix equivalant is something like this :
from popen2 import popen2
output, input = popen2("csh")
# Sets the enviroment.
input.write("se tenv DISPLAY doors:0.0\n")
input.writeinpu t.write(f_mwtes t_exe_str + " " + f_mwtest_args + " " +
os.path.dirname (f_testlwc_str) + " " + f_testlwc_str + "\n")
print "finished"
process the output from the test file.
The problem is at the moment I can't get the process to stop and wait
until the exe has finished executing, the python script executes
everything and then the test file is executed afterwards. I'm thinking
that there must be a switch on the csh or sh command to stop this
happening but I don't know what it is. The unix machines that I'm
working on are all different plat types, so the platform type proberly
won't help you.
NOTE the commands above will be a lot more varied, and are not just
used to set the enviroment up.
Any help would be of great value to me
TIA
