Guido van Rossum 38fff8c4e4 Checking in the code for PEP 357.
This was mostly written by Travis Oliphant.
I've inspected it all; Neal Norwitz and MvL have also looked at it
(in an earlier incarnation).

Tim Peters e564e7f939 new_mmap_object(), Windows flavor.
On a box where sizeof(size_t) == 4, C doesn't define
what happens when a size_t value is shifted right by
32 bits, and this caused test_mmap to fail on Windows
in a debug build.  So use different code to break
the size apart depending on how large size_t actually
is.

This looks like an illusion, since lots of code in this
module still appears to assume sizes can't be more
than 32 bits (e.g., the internal _GetMapSize() still
returns an int), but at least test_mmap passes again.

Neal Norwitz 0e6bc8c260 Patch #1407135, bug #1424041, make mmap.mmap(-1, length) work the same
on both Unix (SVR4 and BSD) and Windows.  Restores behaviour of passing -1
for anonymous memory on Unix.  Use MAP_ANONYMOUS instead of _ANON since
the latter is deprecated according to Linux (gentoo) man pages.

Should we continue to allow mmap.mmap(0, length) to work on Windows?
0 is a valid fd.

Will backport bugfix portions.

Neal Norwitz 3b4fff8079 Fix SF bug #1402308, segfault when using mmap(-1, ...)
This didn't crash on Linux, but valgrind complained.
I'm not sure if this test is valid on Windows.

Will backport.

Jeremy Hylton af68c874a6 Add const to several API functions that take char *.
In C++, it's an error to pass a string literal to a char* function
without a const_cast().  Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.

I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc.  Predictably, there were a large set of functions that
needed to be fixed as a result of these changes.  The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].

One cast was required as a result of the changes:  A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

Neal Norwitz 6eac2005bf Cleanup the previous checkin.
Close the fd in the close method and invalidated it.  Don't try
to close a second time when deallocating.

Andrew M. Kuchling 16581c8614 Set data pointer to NULL after an error; this keeps the mmap_dealloc() function from trying to do msync(-1);munmap(-1).
2.3 bugfix candidate, but this bug isn't critical enough that the fix has to go into 2.3.4

Mark Hammond 62b1ab1b31 Replace DL_IMPORT with PyMODINIT_FUNC and remove "/export:init..." link

Tim Peters c9ffa068d1 SF bug 515943: searching for data with \0 in mmap.
mmap_find_method():  this obtained the string to find via s#, but it
ignored its length, acting as if it were \0-terminated instead.

Someone please run on Linux too (the extended test_mmap works on Windows).

Bugfix candidate.

Guido van Rossum 146483964e Patch supplied by Burton Radons for his own SF bug #487390: Modifying
type.__module__ behavior.

This adds the module name and a dot in front of the type name in every
type object initializer, except for built-in types (and those that
already had this).  Note that it touches lots of Mac modules -- I have
no way to test these but the changes look right.  Apologies if they're
not.  This also touches the weakref docs, which contains a sample type
object initializer.  It also touches the mmap test output, because the
mmap type's repr is included in that output.  It touches object.h to
put the correct description in a comment.

Tim Peters 5ebfd36afa CVS patch #477161: New "access" keyword for mmap, from Jay T Miller.
This gives mmap() on Windows the ability to create read-only, write-
through and copy-on-write mmaps.  A new keyword argument is introduced
because the mmap() signatures diverged between Windows and Unix, so
while they (now) both support this functionality, there wasn't a way to
spell it in a common way without introducing a new spelling gimmick.
The old spellings are still accepted, so there isn't a backward-
compatibility issue here.

Thomas Wouters 1baac7201e Fix SF #441664: Python crash on del of a slice of a mmap
Check for slice/item deletion, which calls slice/item assignment with a NULL
value, and raise a TypeError instead of coredumping. Bugreport and suggested
fix by Alex Martelli.

Tim Peters d401eddf91 Fix new compiler warnings. Also boost "start" from (C) int to long and
return a (C) long:  PyArg_ParseTuple and Py_BuildValue may not let us get
at the size_t we really want, but C int is clearly too small for a 64-bit
box, and both the start parameter and the return value should work for
large mapped files even on 32-bit boxes.  The code really needs to be
rethought from scratch (not by me, though ...).
2001-05-14 23:19:12 +00:00
Greg Stein 834f4dd7c9 Fix the .find() method for memory maps.
1) it didn't obey the "start" parameter (and when it does, we must validate
   the value)
2) the return value needs to be an absolute index, rather than relative to
   some arbitrary point in the file

(checking CVS, it appears this method never worked; these changes bring it
 into line with typical .find() behavior)
