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.).
* fixes the zlib decompress sync flush bug as reported in bug #124981
* avoids repeat calls to (in|de)flateEnd when destroying (de)compression
objects
* raises exception when allocating unused_data fails
* fixes memory leak when allocating unused_data fails
* raises exception when allocating decompress data fails
* removes vestigial code from decompress flush now that decompression
returns all available data
* tidies code so object compress/decompress/flush routines are consistent
compiled only for some versions of Expat, but was no longer needed as the
new implementation works for all versions. Keeping it created multiple
definitions for Expat 1.2, which caused compilation to fail.
in_callback field that's set to true whenever a callback into an
event handler is true. Needed for:
set_error(): Add line number of offset information to the exception
as attributes, so users don't need to parse the text of the
message.
set_error_attr(): New helper function for set_error().
xmlparse_GetInputContext(): New function of the parser object;
returns the document source for an event during a callback, None
at all other times.
xmlparse_SetParamEntityParsing(): Make the signature consistent with
the other parser methods (use xmlparseobject* for self instead of
PyObject*).
initpyexpat(): Don't lose the reference to the exception class!
call_with_frame(),
getcode(): Re-indent to be consistent with the rest of the file.

of nested functions. Either is allowed in a function if it contains
no defs or lambdas or the defs and lambdas it contains have no free
variables. If a function is itself nested and has free variables,
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.
now carry a 'code' attribute that gives the Expat error
number.
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
tested this code thoroughly; it compiles and the basic calls all work
without crashing. Not sure what to actually do with raw sockets though.
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
directory. Modify meaning of -s option to specify the Modules directory.
Add -l option to specify library source directory when building extension
modules. Perhaps these names should be switched to avoid breaking old
code. Add -c compiler option to when emitting rules to build object files.

- In count(), remove(), index(): call RichCompare(Py_EQ).
- Get rid of array_compare(), in favor of new array_richcompare() (a

The final piece of this change...
Strip down Setup.config.in and Setup.dist to the minimal sets required
to get a working Python; setup.py will handle the rest
builds during which he forgot to uncomment crucial library lines in
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
configure.in.
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.

dependencies with libdb that croak pybsddb3). This change moves the
Setup line for dbmmodule to Setup.config.in.
(bugs #115903, #115696)
This is based on a patch by Darrel Gallion. I'm not 100%
sure about this fix, but I haven't managed to come up with
any test case it cannot handle...
-- added some more docstrings
-- fixed typo in scanner class (#125531)
-- the multiline flag (?m) should't affect the \Z operator (#127259)
-- fixed non-greedy backtracking bug (#123769, #127259)
-- added sre.DEBUG flag (currently dumps the parsed pattern structure)
-- fixed a couple of glitches in groupdict (the #126587 memory leak
had already been fixed by AMK)
xreadlines inserted themselves inbetween the two) and clarify that the
normal socket module should be commented out. (Someone also suggested the
latter on c.l.py some time ago, I forget who, sorry.)

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.
documented, and as is reasonable (since it is optional, but there's
another argument following it that may require you to specify a
value). This solves SF bug 121887.
regardless of whether the system getopt() does what we want. This avoids the
hassle with prototypes and externs, and the check to see if the system
getopt() does what we want. Prefix optind, optarg and opterr with _PyOS_ to
avoid name clashes. Add new include file to define the right symbols. Fix
Demo/pyserv/pyserv.c to include getopt.h itself, instead of relying on
Python to provide it.
build on SGI":
* Check for 'sgi' preprocessor symbol, not '__sgi__'
* Surround individual character macros with #ifdef's, instead of making them
all rely on STRICT_SYSV_CURSES
-- fixed negative lookbehind to work correctly at the beginning
of the target string (bug #117242)
-- improved syntax check; you can no longer refer to a group
inside itself (bug #110866)
Direct use of interp->result is deprecated; changing this to
Tcl_GetStringResult(interp) everywhere fixed the problem of losing the

libm result is 0). Cautiously add a few libm exception test cases:
1. That exp(-huge) returns 0 without exception.
2. That exp(+huge) triggers OverflowError.
3. That sqrt(-1) raises ValueError specifically (apparently under glibc linked
with -lieee, it was raising OverflowError due to an accident of the way
mathmodule.c's CHECK() macro happened to deal with Infs and NaNs under gcc).
a Z_BUF_ERROR while decompressing. If it is, assume that this means
the data being decompressed is bad and raise an exception, instead of
just assuming that Z_BUF_ERROR always means that more space is required.

Add Unicode support and error handling to AsString(). Both AsString()
and Merge() now return NULL and set a proper Python exception
condition when an error happens; Merge() and other callers of
AsString() check for errors from AsString(). Also fixed cleanup in
Merge() and Tkapp_Call() return cleanup code; the fv array was not
necessarily completely initialized, causing calls to ckfree() with
garbage arguments!
(Also reindented some lines that were longer than 80 chars and
reformatted some code that used an alien coding standard.)
Versions are defined for Windows and Unix; the Unix
flavor uses sysconf() to get the page size; this avoids
the use of getpagesize(), which is deprecated and
requires an additional library on some platforms
(specifically, Reliant UNIX).

undefined. ccording to MvL, this is safe: the MS_SYNC flag means that
msync() returns when all I/O operations are scheduled; without it, it
waits until they are complete, which is acceptable behavior.
- fixed attributions
- moved decomposition data to a separate table, in preparation
for step 3 (which won't happen before 2.0 final, promise!)
- use relative paths in the generator script
I have a lot more stuff in the works for 2.1, but let's leave
that for another day...
"xml.parsers.expat.error", so it will reflect the public name of the
exception rather than the internal name.
Also change some of the initialization to use the new PyModule_Add*()
convenience functions.
collector will be saved in gc.garbage. This is useful for debugging a
program that creates reference cycles.
- Fix else statements in gcmodule.c to conform to Python coding standards.
subset of Win32 ShellExecute's functionality. Guido wants this because
IDLE's Help -> Docs function currently crashes his machine because of a
conflict between his version of Norton AntiVirus (6.10.20) and MS's
_popen. Docs for startfile are being mailed to Fred (or just read the
docstring -- it tells the whole story).
Changed webbrowser.py to use os.startfile instead of os.popen on Windows.
Changed IDLE's EditorWindow.py to pass an absolute path for the docs
(hardcoding ShellExecute's "directory" arg to "." as used to be done let
IDLE work, but made the startfile command exceedingly obscure for other
uses -- the MS docs are terrible, of course, & still not sure I
understand it).
Note that Windows Python must link with shell32.lib now! That's where
ShellExecute lives.
data and default handlers -- a new reference was being passed to
Py_BuildValue() for the "O" format character; using "N" plugs the leak.
Fixed two other (minor) leaks that occurred on various error conditions.
Removed uses of the UNLESS macro, which makes code hard to read, and is
Evil.
I can't test this, so I'm just checking it in with blind faith in Andy.
I've tested that it doesn't broeak a non-Pth build on Linux.
Changes include:
- There's a --with-pth configure option.
- Instead of _GNU_PTH, we test for HAVE_PTH.
- Better signal handling.
- (The config.h.in file is regenerated in a slightly different order.)
Add contains() as alias for __contains__().
Make PyArg_ParseTuple() formats include the function name.
Based on patch by Denis S. Otkidach <ods@users.sourceforge.net>,
this closes SourceForge patch #101390.
reverse() didn't work at all due to bad arg check.
Fixed that.
Added Brad Chapman to ACKS file, as the proud new owner of two
implicitly copyrighted lines of Python source code <wink>.
Repaired buffer_info's total lack of arg-checking.
Replaced memmove by memcpy in reverse() guts, as memmove is
often slower and the memory areas are guaranteed disjoint.
Replaced poke-and-hope unchecked decl of tmp buffer size by
assert-checked larger tmp buffer.
Got rid of inconsistent spaces before open paren in docstrings.
Added reverse() sanity tests to test_array.py.
This fixes the first half of bug #110611: the immediate exit when ^C
is hit when readline and threads are configured.
Also added a new module variable, readline.library_version.
PyOS_setsig(), instead of directly calling signal() or sigaction().
This fixes the second half of bug #110611: the mysterious ignoring of
the first ^C when readline isn't used.
based on the available headers.
Update comments on the filename extensions used to reflect library
differences.
Added get() and setdefault() methods to the dbm object.
Added docstrings, convert all methods to PyArg_ParseTuple() so that
error messages will have the method names.
glob.glob("k:*py") (i.e., a raw drive letter + colon at the start) were
using the root of the drive rather than the expected Windows behavior
of using the drive's "current directory".
declarations, added some comments where I had to think too hard to
understand what was happening, and changed the primary internal get/set
functions to assert they're passed objects of the correct type instead of
doing runtime tests for that (it's an internal error that "should never
happen", so it's good enough to check it only in the debug build).
Py_FatalError() from module initialization functions. The importing
mechanism already checks for PyErr_Occurred() after module importation
and it Does The Right Thing.

implementation. You don't want to know. I've asked Guido to give this
a critical review (we agreed on the approach, but the implementation
proved more ... interesting ... than anticipated). This will almost
certainly be the highlight of Mark Hammond's day <wink>.
