Well, with a few changes to your code, that would indeed work (you are using
stdin as your pipe. Correct me if I'm wrong but if you intend to read from
it, you need to change it to "stdout = subprocess.PIPE" and the other lines
as well to reflect this change). My Google Summer of Code modifications
Hmm... can't you do this?
if encryptionEnabled:
p = subprocess.Popen(["gpg", "--decrypt", "supersecret.html.gpg"],
stdin = subprocess.PIPE)
fileobj = p.stdin
else:
fileobj = open("notsosecret.html")
I think that works. Is there something this way won't work for? You
can also do the sa
My motivation came from an instance when I was using subprocess.Popen for a
Linux / Windows cross platform program. In part of the program, I was
writing and reading to a cron like object. On Windows, it was a text file
and on Linux it would be the crontab executable. Had I been able to
substitute

"Read from stderr" is just a read. "Write to stderr" is just a write.

I am implementing the file wrapper using changes to subprocess.Popen that
also make it asynchronous and non-blocking so implementing "r+" should be
trivial to do. How about handling stderr? I have the following ideas: leave
out support for reading from stderr, make it so that there is an optional
