Category: Documentation Group: Python 2.5 >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Brian Wellington (bwelling) >Assigned to: Reinhold Birkenfeld (birkenfeld) Summary: os.environ documentation should mention unsetenv Initial Comment: The (current) documentation for os.environ says: --- If the platform supports the putenv() function, this mapping may be used to modify the environment as well as query the environment. putenv() will be called automatically when the mapping is modified. --- Some platforms (Solaris 8 and 9, at least) have putenv() but not unsetenv(), which means that setting environment variables by assigning values in os.environ works, but unsetting them by deleting from os.environ doesn't. This is confusing, and should at least be documented (if for no other reason than no one else should waste several hours figuring this out). This was tested with Python 2.4.1 and earlier versions. I'd suggest documenting os.unsetenv() in 6.1.1 (Process Parameters) of the manual, and modifying the above text to say something like: --- If the platform supports the putenv() and unsetenv() functions, this mapping may be used to modify the environment as well as query the environment. putenv() will be called automatically when an entry in the mapping is added or changed, and unsetenv() will be called automatically when an entry is deleted. --- ---------------------------------------------------------------------- >Comment By: Reinhold Birkenfeld (birkenfeld) Date: 2005-06-25 20:47 Message: Logged In: YES user_id=1188172 Fixed as Doc/lib/libos.tex r1.158, r1.146.2.4.
