Is there any way to write binary output to sys.stdout in Python 2.x? In Python 3.x, you can just use sys.stdout.buffer (or detach stdout, etc...), but I haven't been able to find any solutions for Python 2.5/2.6.
EDIT, Solution: From ChristopheD's link, below:
import sys
if sys.platform == "win32":
import os, msvcrt
msvcrt.setmode(sys.stdout.fileno(), os.O_BINARY)
EDIT: I'm trying to push a PDF file (in binary form) to stdout for serving up on a web server. When I try to write the file using sys.stdout.write, it adds all sorts of carriage returns to the binary stream that causes the PDF to render corrupt.
EDIT 2: For this project, I need to run on a Windows Server, unfortunately, so Linux solutions are out.
Simply Dummy Example (reading from a file on disk, instead of generating on the fly, just so we know that the generation code isn't the issue):
file = open('C:\\test.pdf','rb')
pdfFile = file.read()
sys.stdout.write(pdfFile)
Which platform are you on?
You could try this recipe if you're on Windows (the link suggests it's Windows specific anyway).
if sys.platform == "win32":
import os, msvcrt
msvcrt.setmode(sys.stdout.fileno(), os.O_BINARY)
There are some references on the web that there would/should be a function in Python 3.1 to reopen sys.stdout
in binary mode but I don't really know if there's a better alternative then the above for Python 2.x.
