explicit comparison function case: use PyObject_Call instead of
PyEval_CallObject. Same thing in context, but gives a 2.4% overall
speedup when sorting a list of ints via list.sort(__builtin__.cmp).
more trivial lexical helper macros so that uses of these guys expand
to nothing at all when they're not enabled. This should help sub-
standard compilers that can't do a good job of optimizing away the
previous "(void)0" expressions.
Py_DECREF: There's only one definition of this now. Yay! That
was that last one in the family defined multiple times in an #ifdef
maze.
Py_FatalError(): Changed the char* signature to const char*.
_Py_NegativeRefcount(): New helper function for the Py_REF_DEBUG
expansion of Py_DECREF. Calling an external function cuts down on
the volume of generated code. The previous inline expansion of abort()
didn't work as intended on Windows (the program often kept going, and
the error msg scrolled off the screen unseen). _Py_NegativeRefcount
calls Py_FatalError instead, which captures our best knowledge of
how to abort effectively across platforms.
Repair segfaults and infinite loops in COUNT_ALLOCS builds in the
presence of new-style (heap-allocated) classes/types.
Bugfix candidate. I'll backport this to 2.2. It's irrelevant in 2.1.
In a fresh interpreter, type.mro(tuple) would segfault, because
PyType_Ready() isn't called for tuple yet. To fix, call
PyType_Ready(type) if type->tp_dict is NULL.
This patch enhances Python/import.c/find_module() so
that unicode objects found in sys.path will be treated
as legal directory names (The current code ignores
anything that is not a str). The unicode name is
converted to str using Py_FileSystemDefaultEncoding.
These built-in functions are replaced by their (now callable) type:
slice()
buffer()
and these types can also be called (but have no built-in named
function named after them)
classobj (type name used to be "class")
code
function
instance
instancemethod (type name used to be "instance method")
The module "new" has been replaced with a small backward compatibility
placeholder in Python.
A large portion of the patch simply removes the new module from
various platform-specific build recipes. The following binary Mac
project files still have references to it:
Mac/Build/PythonCore.mcp
Mac/Build/PythonStandSmall.mcp
Mac/Build/PythonStandalone.mcp
[I've tweaked the code layout and the doc strings here and there, and
added a comment to types.py about StringTypes vs. basestring. --Guido]
library. Since multiple versions can be installed simultaneously, it's
crucial that you only select libraries and header files which are compatible
with each other. Version checking is done from highest version to lowest.
Building using version 1 of Berkeley DB is disabled by default because of
the hash file bugs people keep rediscovering. It can be enabled by
uncommenting a few lines in setup.py. Closes patch 553108.
This was a simple typo. Strange that the compiler didn't catch it!
Instead of WHY_CONTINUE, two tests used CONTINUE_LOOP, which isn't a
why_code at all, but an opcode; but even though 'why' is declared as
an enum, comparing it to an int is apparently not even worth a
warning -- not in gcc, and not in VC++. :-(
Will fix in 2.2 too.
[ 400998 ] experimental support for extended slicing on lists
somewhat spruced up and better tested than it was when I wrote it.
Includes docs & tests. The whatsnew section needs expanding, and arrays
should support extended slices -- later.
While I was at it, I added a tp_clear handler and changed the
tp_dealloc handler to use the clear_slots helper for the tp_clear
handler.
Also tightened the rules for slot names: they must now be proper
identifiers (ignoring the dirty little fact that <ctype.h> is locale
sensitive).
Also set mp->flags = READONLY for the __weakref__ pseudo-slot.
Most of this is a 2.2 bugfix candidate; I'll apply it there myself.
BOM_UTF32, BOM_UTF32_LE and BOM_UTF32_BE that represent the Byte
Order Mark in UTF-8, UTF-16 and UTF-32 encodings for little and
big endian systems.
The old names BOM32_* and BOM64_* were off by a factor of 2.
This closes SF bug http://www.python.org/sf/555360
Change the module constructor (module_init) to have the signature
__init__(name:str, doc=None); this prevents the call from type_new()
to succeed. While we're at it, prevent repeated calling of
module_init for the same module from leaking the dict, changing the
semantics so that __dict__ is only initialized if NULL.
Also adding a unittest, test_module.py.
This is an incompatibility with 2.2, if anybody was instantiating the
module class before, their argument list was probably empty; so this
can't be backported to 2.2.x.
[ 559250 ] more POSIX signal stuff
Adds support (and docs and tests and autoconfery) for posix signal
mask handling -- sigpending, sigprocmask and sigsuspend.
for 'str' and 'unicode', and can be used instead of
types.StringTypes, e.g. to test whether something is "a string":
isinstance(x, string) is True for Unicode and 8-bit strings. This
is an abstract base class and cannot be instantiated directly.
and the .seed() and .whseed() methods failed to reset it. In other
words, setting the seed didn't completely determine the sequence of
results produced by random.gauss(). It does now. Programs repeatedly
mixing calls to a seed method with calls to gauss() may see different
results now.
Bugfix candidate (random.gauss() has always been broken in this way),
despite that it may change results.
This now does a dynamic analysis of which elements are so frequently
repeated as to constitute noise. The primary benefit is an enormous
speedup in find_longest_match, as the innermost loop can have factors
of 100s less potential matches to worry about, in cases where the
sequences have many duplicate elements. In effect, this zooms in on
sequences of non-ubiquitous elements now.
While I like what I've seen of the effects so far, I still consider
this experimental. Please give it a try!
left and right type were of the same type and not classic instances.
This shortcut is dangerous for proxy types, because it means that
coerce(Proxy(1), Proxy(2.1)) leaves Proxy(1) unchanged rather than
turning it into Proxy(1.0).
In an ever-so-slight change of semantics, I now only take the shortcut
when the left and right types are of the same type and don't have the
CHECKTYPES feature. It so happens that classic instances have this
flag, so the shortcut is still skipped in this case (i.e. nothing
changes for classic instances). Proxies also have this flag set
(otherwise implementing numeric operations on proxies would become
nightmarish) and this means that the shortcut is also skipped there,
as desired. It so happens that int, long and float also have this
flag set; that means that e.g. coerce(1, 1) will now invoke
int_coerce(). This is fine: int_coerce() can deal with this, and I'm
not worried about the performance; int_coerce() is only invoked when
the user explicitly calls coerce(), which should be rarer than rare.
better auto-recognition of a Jython file vs. a CPython (or agnostic)
file by looking at the #! line more closely, and inspecting the import
statements in the first 20000 bytes (configurable). Specifically,
(py-import-check-point-max): New variable, controlling how far into
the buffer it will search for import statements.
(py-jpython-packages): List of package names that are Jython-ish.
(py-shell-alist): List of #! line programs and the modes associated
with them.
(jpython-mode-hook): Extra hook that runs when entering jpython-mode
(what about Jython mode? <20k wink>).
(py-choose-shell-by-shebang, py-choose-shell-by-import,
py-choose-shell): New functions.
(python-mode): Use py-choose-shell.
(jpython-mode): New command.
(py-execute-region): Don't use my previous hacky attempt at doing
this, use the new py-choose-shell function.
One other thing this file now does: it attempts to add the proper
hooks to interpreter-mode-alist and auto-mode-alist if they aren't
already there. Might help with Emacs users since that editor doesn't
come with python-mode by default.
Allows for some customization of the underlying comint buffer.
(py-shell): Call the new hook.
(info-lookup-maybe-add-help): A new call suggested by Milan Zamazal to
make lookups in the Info documentation easier.
closes SF #514433
can now pass 'None' as the filename for the bsddb.*open functions,
and you'll get an in-memory temporary store.
docs are ripped out of the bsddb dbopen man page. Fred may want to
clean them up.
Considering this for 2.2, but not 2.1.
(py-mode-map): Bind py-help-at-point to f1 as well as C-c C-h
(py-help-at-point): Make sure the symbol is quoted so things like
pydoc.help('sys.platform') work correctly. Also, leave the *Python
Output* buffer in help-mode; this may be a bit more controversial.
to call pychecker on the current file, add a face for pseudo
keywords self, None, True, False, and Ellipsis. Specifically,
(py-pychecker-command, py-pychecker-command-args): New variables.
(py-pseudo-keyword-face): New face variable, defaulting to a copy of
font-lock-keyword-face.
(python-font-lock-keywords): Add an entry for self, None, True, False,
Ellipsis to be rendered in py-pseudo-keyword-face.
(py-pychecker-history): New variable.
(py-mode-map): Bind C-c C-w to py-pychecker-run.
(py-pychecker-run): New command.
"help-on-symbol-at-point" feature which uses pydoc to provide help on
the symbol under point, if available.
Mods include some name changes, a port to Emacs, binding the command
to C-c C-h, and providing a more informative error message if the
symbol's help can't be found (through use of a nasty bare except).
Note also that py-describe-mode has been moved off of C-c C-h m; it's
now just available on C-c ?
Closes SF patch #545439.
#! line, use the command on that line as the shell command to use to
execute the region. I.e. if the region looks like
----------------
#! /usr/bin/env python1.5
print 'hello world'.startswith('hello')
----------------
you'll get an exception! :)
This closes SF bug #232398.
python-mode file, py-which-shell would have been nil and the command
to use would not get set correctly. This changes things so that 1)
the temporary file has a .py extension, 2) the temporary file is put
into python-mode, and 3) the temporary file's py-which-shell is
captured in a local `shell' variable, which is used to calculate the
command to use. Closes SF bug #545436.
(py-parse-state): Rip out the XEmacs-specific calls to
buffer-syntactic-context, which can get quite confused if there's an
open paren in column zero say, embedded in a triple quoted string.
This was always a performance hack anyway, and computers are fast
enough now that we should be able to get away with the slower, more
portable, full-parse branch. Closes SF bug #451841.
