[Jython-dev] javaos.py for OS/400

[Humbel O. <Otm...@bi...>]

Hello Kevin, others.

please let me give feedback how work is going on.
	System.getProperty( "os.name" ) returns "OS/400",=20
I therefore suggest we stick to platform =3D "os400" from now on ...

On the positive side, I can type
	>>> import os
	>>> os.system( 'env' )
	>>> os.system( 'java' )
and get the correct output.


Open issues:

1.
Process.getInputStream() is in a foreign encoding (EBCDIC I guess), so I
have to decode it using a FilterInputStream. I made some exercises with
Per Gummedal's lib/encodings/ebcdic.py file from the CPython
implementation
	http://home.no.net/pgummeda
but with no success.

2.
The two commands above produce a different stream encoding, e.g.:
	env results in int value 37 for "\n",
	java results in int value 21 for "\n"
Now I am searching for a way to handle that correctly.

3.=20
I cannot yet type=20
	>>> os.system('java -version')
meaning any command taking an argument (which is valid on the native
shell) leads to a 'invalid option' error message. Still searching here.

4.=20
	>>> os.system( 'echo hello' )
gives no output at all - difficult to pass os.__test() this way :-(



Asking for a little more patience,
Oti.
