483100 - Python output buffering makes xpcshell test output not-real-time

Status: RESOLVED FIXED

(Testing :: XPCShell Harness, defect)

Description

[Jeff Walden [:Waldo]]

Attachment: PYTHONUNBUFFERED=1

make -s -C obj-i386-apple-darwin8.11.1/netwerk/test/httpserver/ check

prints all output when it completes;

PYTHONUNBUFFERED=1 make -s -C obj-i386-apple-darwin8.11.1/netwerk/test/httpserver/ check

prints each test line incrementally.

There's probably a better way, but this works and is the path of least resistance going forward.

That's gross. There are a couple of nicer suggestions here:
http://stackoverflow.com/questions/107705/python-output-buffering
1) stick -u in the hash-bang line at the top of the file
2) sys.stdout = os.fdopen(sys.stdout.fileno(), 'w', 0) (goofy reopening of stdout)

I think the former is less crappy.

#1 doesn't work, that's a comment in Python.  #2, are you serious?  That's worse than the envvar hack.  :-P

Just stick it on the same line as $(PYTHON), please.
