Michael Hudson suggested this fox for the Tru64 problem (SF bug
232597). It looks reasonable, it works on Tru64, and it doesn't beak
anything on Linux, so I say go for it.
of 2-space and 4-space indents. Whatever, when I saw the checkin diff it
was clear that what my editor thinks a tab means didn't match this module's
belief. Removed all the tabs from the lines I added and changed, left
everything else alone.
pickled into the signed(!) 4-byte BININT format, so were getting unpickled
again as negative ints. Repaired that.
Added some minimal docs at the top about what I've learned about the pickle
format codes (little of which was obvious from staring at the code,
although that's partly because all the size-related bugs greatly obscured
the true intent of the code).
Happy side effect: because save_int() needed to grow a *proper* range
check in order to fix this bug, it can now use the more-efficient BININT1,
BININT2 and BININT formats when the long's value is small enough to fit
in a signed 4-byte int (before this, on a sizeof(long)==8 box it always
used the general INT format for negative ints).
test_cpickle works again on sizeof(long)==8 machines. test_pickle is
still busted big-time.
binary pickle, and the latter contains a pickle of a negative Python
int i written on a sizeof(long)==4 box (and whether by cPickle or
pickle.py), it's read incorrectly as i + 2**32. The patch repairs that,
and allows test_cpickle.py (to which I added a relevant test case earlier
today) to work again on sizeof(long)==8 boxes.
There's another (at least one) sizeof(long)==8 binary pickle bug, but in
pickle.py instead. That bug is still there, and test_pickle.py doesn't
catch it yet (try pickling and unpickling, e.g., 1 << 46).
where sizeof(long)==8. This *was* broken on boxes where signed right
shifts didn't sign-extend, but not elsewhere. Unfortunately, apart
from the Cray T3E I don't know of such a box, and Guido has so far
refused to buy me any Cray machines for home Python testing <wink>.
More immediately interesting would be if someone could please test
this on *any* sizeof(long)==8 box, to make sure I didn't break it.

This may or may not fix the problem for me (Mandrake 7.2 on a Dell

that it's the kernel version in combination with the driver.

If a module has a future statement enabling nested scopes, they are
also enable for the exec statement and the functions compile() and
execfile() if they occur in the module.
If Python is run with the -i option, which enters interactive mode
after executing a script, and the script it runs enables nested
scopes, they are also enabled in interactive mode.
XXX The use of -i with -c "from __future__ import nested_scopes" is
not supported. What's the point?
To support these changes, many function variants have been added to
pythonrun.c. All the variants names end with Flags and they take an
extra PyCompilerFlags * argument. It is possible that this complexity
will be eliminated in a future version of the interpreter in which
nested scopes are not optional.

the problems. This fixes SF buf 405583.
There is also a C API change: PyFrame_New() is reverting to its

mistake. XXX Is this okay between beta releases?

the internal API function to release the interned strings as the very
last thing before returning status. This aids in memory use debugging
because it eliminates a huge source of noise from the reports. This
is never called during normal (non-debugging) use because releasing
the interned strings slows Python's shutdown and isn't necessary
anyway because the system will always reclaim the memory.

The bug report title isn't correct, but was on the right track.
Rev 2.13 applied a patch intended to improve asinh and acosh, but the
author mistakenly replaced the body of asin with their new code for asinh.
See bug report for all the gory details.
This patch: (a) puts the "new" (as of 2.13) asinh code into the asinh
function; and, (b) repairs asin via what Abramowitz & Stegun say it should
be (which is probably the same as what 2.12 did for asin, although I got
tired of matching parentheses before being 100% sure of that -- and I don't
care! The source of the old code is a mystery, and I *know* why I picked
the new code.).

either is illegal.
Revise the symtable to use a PySymtableEntryObject, which holds all
the revelent information for a scope, rather than using a bunch of
st_cur_XXX pointers in the symtable struct. The changes simplify the
internal management of the current symtable scope and of the stack.
Added new C source file: Python/symtable.c. (Does the Windows build
process need to be updated?)
As part of these changes, the initial _symtable module interface
introduced in 2.1a2 is replaced. A dictionary of
PySymtableEntryObjects are returned.

Added support for additional handlers for Expat 1.95.*, including
XmlDeclHandler, EntityDeclHandler, ElementDeclHandler, and
AttlistDeclHandler. Associated constants are in the 'model'
sub-object.
Added two new attributes to the parser object: ordered_attributes and
specified_attributes. These are used to control how attributes are
reported and which attributes are reported.
Adds support for raw packets (AF_PACKET) under Linux. I haven't

Not sure what other platforms this might be useful for.
This involves changing the zlib build process to build zlib itself from sources, then use that library. Also updated are the comments to reflect the new official home of zlib, and add Windows specific notes regarding the build process.
"Partial" as the code uses sys.prefix in an attempt to locate 'w9xpopen.exe', but sys.prefix is not set if Python can't find it itself. So this _still_ fails in Pythonwin, but I am committing the patch for 2 reasons:
* Embedded apps that set sys.prefix or use PYTHONHOME will work
* The exception raised on failure to find the executable is far more obvious

Setup, walks into Guido's East End nightclub with a tactical nuclear
weapon on his shoulder. Said nuclear weapon is promptly deployed
exactly where it will do the most good, right in the middle of

With this patch, the set of libraries autoconfigured in is extended to
include ndbm, gdbm, and crypt. This essentially eliminates any need to
tweak Setup for a normal Linux build.

The solution doesn't use the unicode-escape encoding; that has other
problems (it seems not 100% reversible). Rather, it transforms the
input Unicode object slightly before encoding it using
raw-unicode-escape, so that the decoding will reconstruct the original
string: backslash and newline characters are translated into their
\uXXXX counterparts.
This is backwards incompatible for strings containing backslashes, but
for some of those strings, the pickling was already broken.
Note that SF bug #123634 complains specifically that cPickle fails to
unpickle the pickle for u'' (the empty Unicode string) correctly.
This was an off-by-one error in load_unicode().
XXX Ugliness: in order to do the modified raw-unicode-escape, I've
cut-and-pasted a copy of PyUnicode_EncodeRawUnicodeEscape() into this
file that also encodes '\\' and '\n'. It might be nice to migrate
this into the Unicode implementation and give this encoding a new name
('half-raw-unicode-escape'? 'pickle-unicode-escape'?); that would help
pickle.py too. But right now I can't be bothered with the necessary
infrastructural changes.
