This patch does several things to termios:
(1) changes all functions to be METH_VARARGS
(2) changes all functions to be able to take a file object as the
first parameter, as per
http://mail.python.org/pipermail/python-dev/2001-February/012701.html
(3) give better error messages
(4) removes a bunch of comments that just repeat the docstrings
(5) #includes <termio.h> before #including <sys/ioctl.h> so more
#constants are actually #defined.
(6) a couple of docstring tweaks
I have tested this minimally (i.e. it builds, and
doesn't blow up too embarassingly) on OSF1/alpha and
on one of the sf compile farm's solaris boxes, and
rather more comprehansively on my linux/x86 box.
It still needs to be tested on all the other platforms
we build termios on.
This closes the code portion of SF patch #417081.
while not generally a good idea, this is used by RDF users, and works
to implement RDF-style namespace+localname concatenation as defined
in the RDF specifications. (This also corrects a backwards-compatibility
bug.)
Be more conservative while clearing out handlers; set the slot in the
self->handlers array to NULL before DECREFing the callback.
Still more adjustments to make the code style internally consistent.
OpenSSL versions beore 0.9.5. This just is too experimental to be
worth it, especially since the user would have to do some severe
hacking of the Modules/Setup file to even enable the EGD code, and
without the EGD code it would always spit out a warning on some
systems -- even when socket.ssl() is not used. Fixing that properly
is not my job; the EGD patch is clearly not so important that it
should hold up the 2.1 release.
always:
- #undef HAVE_CONFIG_H (because otherwise chardefs.h tries to include
strings.h)
- #include readline.h and history.h
and we never declare any readline function prototypes ourselves.
This makes it compile with readline 4.2, albeit with a few warnings.
Some of the remaining warnings are about completion_matches(), which
is renamed to rl_completion_matches().
I've tested it with various other versions, from 2.0 up, and they all
seem to work (some with warnings) -- but only on Red Hat Linux 6.2.
Fixing the warnings for readline 4.2 would break compatibility with
3.0 (and maybe even earlier versions), and readline doesn't seem to
have a way to test for its version at compile time, so I'd rather
leave the warnings in than break compilation with older versions.
problem reported by Neil Schemenauer on python-dev on 4/12/01, wth
subject "Problem with SSL and socketmodule on Debian Potato?".
It's tentative because Moshe objected, but Martin rebutted, and Moshe
seems unavailable for comments.
(Note that with OpenSSL 0.9.6a, I get a lot of compilation warnings
for socketmodule.c -- I'm assuming I can safely ignore these until 2.1
is released.)
before calling any callbacks. This is important
since the callback objects only look at themselves
to determine that they are invalide. This change
avoids a segfault when callbacks use a different
reference to an object in the process of being
deallocated.
This fixes SF bug #415660.
(with modification of existing dict elements!).
This is part of SF patch #409864: lazy fix for Pings bizarre scoping
crash.
The adaptation I made to Michael's patch was to change the error
handling to avoid masking other errors (moving the specific error
message to inside test_dict_inner()), and to insert a test for
dict==NULL at the start.
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.
handling of EAGAIN.
This may or may not fix the problem for me (Mandrake 7.2 on a Dell
Optiplex GX110 desktop): I can't hear the output, but it does pass the
test now. It doesn't fix the problem for Fred (Mandrake 7.2 on a Dell
Inspiron 7500 which has the Maestro sound drivers). Fred suspects
that it's the kernel version in combination with the driver.

tracked as soon as it is clear; this can decrease the number of roots for
the cycle detector sooner rather than later in applications which hold on
to weak references beyond the time of the invalidation.
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.
with free variables. Thanks to Martin v. Loewis for finding two of
the problems. This fixes SF buf 405583.
There is also a C API change: PyFrame_New() is reverting to its
pre-2.1 signature. The change introduced by nested scopes was a
mistake. XXX Is this okay between beta releases?
cell_clear(), the GC helper, must decref its reference to break
cycles.
frame_dealloc() must dealloc all cell vars and free vars in addition
to locals.
eval_code2() setup code must INCREF cells it copies out of the
closure.
The STORE_DEREF opcode implementation must DECREF the object it passes
to PyCell_Set().
these can be missing on some (all?) Irix and Tru64 versions.

Solaris also does not define CBAUDEX; it is not clear that CBAUDEXT
(which is defined there) is the same thing, so we only protect against
the lack of CBAUDEX.
Reported by Greg V. Wilson.
Fixed recno support (keys are integers rather than strings).
Work around DB bug that cause stdin to be closed by rnopen() when the
DB file needed to exist but did not (no longer segfaults).
This closes SF tracker patch #403445.
Also wrapped some long lines and added whitespace around operators -- FLD.
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.
(Fred, I'll leave the doc changes to you, because I don't know if you
want to delete libsoundex.tex or leave it in.
Someone else will have to tweak PC/os2vacpp/{config.c,makefile} and
PCbuild/pythoncore.dsp, both of which refer to soundex.c)
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

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

xmlparse_SetParamEntityParsing(): Make the signature consistent with
the other parser methods (use xmlparseobject* for self instead of
PyObject*).

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
