Andrew M. Kuchling ea34a84e54 Patch from Lorenzo M. Catucci:
I discovered the [MREMAP_MAYMOVE] symbol is only defined when _GNU_SOURCE is
defined; therefore, here is the change: if we are compiling for linux,
define _GNU_SOURCE before including mman.h, and all is done.

Andrew M. Kuchling 6fef30e1fa Support resizing the mapping depending on whether HAVE_MREMAP is defined
Remove two unused variables

Andrew M. Kuchling 70d2742fce Patch from Trent Mick:
The seek() method is broken for any 'whence' value (seek from
	start, current, orend) other than the default. I have a patch
	that fixes that as well as gets mmap'd files working on
	Linux64 and Win64.

Andrew M. Kuchling 7b9fb92932 Fix the size() method to return the size of the file on Unix, not the
size of the mapped area.  This seems to be what the Windows version does.
This change requires keeping around the fd of the mapped file.

Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)

Guido van Rossum 36d4f8b0ec Correct fix by Mark Favas for the cast problems. 2000-04-10 21:34:37 +00:00
Guido van Rossum e110dcfa86 I've had complaints about the comparison "where >= 0" before -- on
IRIX, it doesn't even compile.  Added a cast: "where >= (char *)0".

This patch fixes the mmap module on Windows 9x.

Fred Drake 56a87a0905 Patch from Hrvoje Niksic <hniksic@iskon.hr>:
The bug is in mmap_read_line_method(), and its loop that searches for
newlines.  After the loop reaches EOF, eol is incremented and points
after the end of the memory.  This results in readline() method
sometimes picking up and returning a byte after the end of the string.
This is usually a bogus \0, but it could cause SIGSEGV if it's after
the end of the page).

The patch fixes the problem.  Also, it uses memchr() for finding a
character, which is in fact the "strnchr" the comment is asking for.
memchr() is already used in Python sources, so there should be no
portability problems.

Guido van Rossum 09fdf07315 Hacked for Win32 by Mark Hammond.
Reformatted for 8-space tabs and fitted into 80-char lines by GvR.

Mark writes:

* the Win32 version now accepts the same args as the Unix version.
The win32 specific "tag" param is now optional.  The end result is
that the exact same test suite runs on Windows (definately a worthy
goal!).

* I changed the error object.  All occurences of the error, except
for 1, corresponds to an underlying OS error.  This one was changed
to a ValueError (a better error for that condition), and the module
error object is now simply EnvironmentError.  All win32 error
routines now call the new Windows specific error handler.

Andrew M. Kuchling 1ed7d2d2b8 Added mmap module -- map a view of a file into memory on Win32 and Unix.
(Needs testing on Win32.)
