[New-bugs-announce] [issue27525] Wrong OS header on file created by gzip module

[Dor Dankner]

New submission from Dor Dankner:

The gzip module generates files with wrong OS header, by putting "Unknown" OS, instead of checking and filling the user's OS.
>From the gzip RFC (rfc1952): "This identifies the type of file system on which compression took place. This may be useful in determining end-of-line convention for text files."

The following patch contains a fix that fills the current OS flag (and testcase ;) )

* The bug is relevant to python 2.x too, but I did not test the patch on it.
** also, I did not run the testcase on Win/Mac, however it should work.
