nit: two newlines

[iannucci, 2014/07/11 02:14:46]

Done.

Poor 'tbz2' :(

[iannucci, 2014/07/11 02:14:46]

Acknowledged.

[dnj, 2014/07/10 16:06:18]

Ugh Windows is stupid. With a streaming transfer, you can eliminate any temp
file grossness:
proc = subprocess.Popen(['gsutil', 'cp', '-', BUCKET + new_fname],
stdin=subprocess.PIPE)
proc.communicate(data)
if proc.returncode != 0:
    raise subprocess.CalledProcessError("wat")

[iannucci, 2014/07/11 02:14:46]

Derp. Done.

+    with open(tempname, 'wb') as f:
+      f.write(data)
+
+    new_fname = sha + ext
+    subprocess.check_call(['gsutil', 'cp', tempname, BUCKET + new_fname])
+    print
+  finally:
+    os.unlink(tempname)
+
+  print new_fname
+

+if __name__ == '__main__':
+  sys.exit(main())
