[New-bugs-announce] [issue8640] subprocess: add envb argument to Popen constructor (Python3, POSIX only)

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

Python 3.2 has now its os.environb, the bytes version of os.environ. subprocess should get a new envb argument to be able to use pure bytes environmental variables. Examples:

   subprocess.call([b'env], envb={b'PATH': b'/usr/bin'})

and

   envb = os.environb.copy()
   envb[b'PATH'] = b'/usr/bin'
   subprocess.call([b'env], envb=envb)

Specify both env and envb would raise an exception. envb should only be available on POSIX (as os.environb).

Related issues: #8513 (subprocess: support bytes program name) and #8603 (os.environb).
