Hi All,
There seems to be a problem using Python for "External Source
Control", CC.NET Version - 1.4.1.3795 :-(
What I have done to try this out:
PYTHON SCRIPT (The essentials) - sourceControl.py:
# The modules entry point when executed as a command line script.
def main( args ):
print args
cmdLine = ""
for a in args:
cmdLine = cmdLine + a + " "
debugFile = open ( 'C:\\automation\\SC-Debug.txt', 'a' )
debugFile.write( '\n--> ' + cmdLine )
debugFile.close()
return 0
# Ensure we only run command line functionality when we are the
__main__ module .
if __name__ == "__main__":
sys.exit( main( sys.argv[0:] ) )
As you can see, it doesn't do much... it simply prints the
applications call arguments to STDIO and at the same time appends
(creates if necessary) the arguments to a file in case I miss STDIO.
But the script will never get called!
The ccnet.config has this section:
<!-- External Source Control, Calls Python Script to retrieve
the
#NEXT Changelist not #HEAD -->
<sourcecontrol type="external">
<executable>python</executable>
<args>C:\automation\sourceControl.py</args>
<autoGetSource>true</autoGetSource>
<labelOnSuccess>false</labelOnSuccess>
<timeout units="minutes">5</timeout>
</sourcecontrol>
Here's the catch! Looking at the server log, see if you can spot the
problem:
[projectSample:DEBUG] Preparing to run source control command:
python GETMODS "2009-01-27 09:04:56" "2009-01-26 14:12:52" C:
\automation\sourceControl.py
[projectSample:DEBUG] python: can't open file 'GETMODS': [Errno
2] No such file or directory
[projectSample:ERROR] Exception: Source control operation
failed: python: can't open file 'GETMODS': [Errno 2] No such file or
directory
PYTHON requires the format: PYTHON <PYTHON_SCRIPT.PY> [ARGS]
Changing the ccnet.config like so, does not fix the problem:
<executable>c:\python26\python
C:\automation\sourceControl.py</
executable>
<args></args>
Also does not work the server log reports:
[projectSample:DEBUG] Preparing to run source control command: c:
\python26\python C:\automation\sourceControl.py GETMODS "2009-01-27
09:25:00" "2009-01-26 14:12:52"
[projectSample:ERROR] INTERNAL ERROR: Unable to execute file [c:
\python26\python C:\automation\sourceControl.py]. The file may not
exist or may not be executable.
This starts out looking promising but then fails, "Unable to execute
file", (incidentally, this same problem happens with <EXEC/> tasks).
:-(
One for the issue tracker I think!
Has anyone got around this?
Regards,
Shaun
