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.
Update the comments at the top of the file.
option. It was the cause of at least one way UNWISE.EXE could vanish
(install a python; uninstall it; install it again; reboot the machine;
abracadabra the uinstaller is gone).
Bugfix candidate, but I'll backport it myself.
Add a method zfill to str, unicode and UserString and change
Lib/string.py accordingly.
This activates the zfill version in unicodeobject.c that was
commented out and implements the same in stringobject.c. It also
adds the test for unicode support in Lib/string.py back in and
uses repr() instead() of str() (as it was before Lib/string.py 1.62)
when PyType_Ready() was called, if ob_type was found to be NULL, it
was always set to &PyType_Type; now it is set to base->ob_type,
where base is tp_base, defaulting to &PyObject_Type.
- PyType_Ready() accidentally did not inherit tp_is_gc; now it does.
Bugfix candidate.
This patch makes it possible to pass Warning instances as the first
argument to warnings.warn. In this case the category argument
will be ignored. The message text used will be str(warninginstance).
searches. This is added after /tmp. Closes SF bug #505488, except
that /var/tmp comes after /tmp instead of the patch's suggestion of
putting it before /usr/tmp.
implementation to match the documentation for
py-honor-comment-indentation w.r.t. not nil or t value. In that case
it should still ignore ## for indentation purposes. Closes SF bug
#523825, w/ patch provided by Christian Stork (mod'd by Barry).
Python 2.2.1 candidate.
As promised in my response to the bug report, I'm not really fixing
it; in fact, one could argule over what the proper fix should do.
Instead, I'm adding a little magic that raises TypeError if you try to
pickle an instance of a class that has __slots__ but doesn't define or
override __getstate__. This is done by adding a bozo __getstate__
that always raises TypeError.
Bugfix candidate (also the checkin to typeobject.c, of course).
dropping MS's inadequate _chsize() function. This was inspired by
SF patch 498109 ("fileobject truncate support for win32"), which I
rejected.
libstdtypes.tex: Someone who knows should update the availability
blurb. For example, if it's available on Linux, it would be good to
say so.
test_largefile: Uncommented the file.truncate() tests, and reworked to
do more. The old comment about "permission errors" in the truncation
tests under Windows was almost certainly due to that the file wasn't open
for *write* access at this point, so of course MS wouldn't let you
truncate it. I'd be appalled if a Unixish system did.
CAUTION: Someone should run this test on Linux (etc) too. The
truncation part was commented out before. Note that test_largefile isn't
run by default.
Due to the bizarre definition of _PyLong_Copy(), creating an instance
of a subclass of long with a negative value could cause core dumps
later on. Unfortunately it looks like the behavior of _PyLong_Copy()
is quite intentional, so the fix is more work than feels comfortable.
This fix is almost, but not quite, the code that Naofumi Honda added;
in addition, I added a test case.
rexec.
When using a restricted environment, imports of copy will fail with an
AttributeError when trying to access types.CodeType.
Bugfix candidate (all the way back to 1.5.3, but at least 2.1.3 and
2.2.1).
A file-static "threads" dict mapped thread IDs to Windows handles, but
was never referenced, and entries never got removed. This gets rid of
the YAGNI-dict entirely.
Bugfix candidate.
helper module _ssl.
The support for the RAND_* APIs in _ssl is now only enabled
for OpenSSL 0.9.5 and up since they were added in that
release.
Note that socketmodule.* should really be renamed to _socket.* --
unfortunately, this seems to lose the CVS history of the file.
Please review and test... I was only able to test the header file
chaos in socketmodule.c/h on Linux. The test run through fine
and compiles don't give errors or warnings.
WARNING: This patch does *not* include changes to the various
non-Unix build process files.
where their capabilities intersect. Would be nice if people using non-
MSVC compilers (Borland etc) took a whack at doing something similar for
them (this code relies on the MS _cwait function).
Instead of sending the real user and host, use "anonymous@" (i.e. no
host name at all!) as the default anonymous FTP password. This avoids
privacy violations.

Removed the ancient "#define ANY void".
Bugfix candidate? Hard call. The bug report claims the existence of
this #define creates conflicts with other packages, which is easy to
believe. OTOH, some extension authors may still be relying on its
presence. I'm afraid you can't win on this one.
binascii_b2a_base64(): We didn't allocate enough buffer space for very
short inputs (e.g., a 1-byte input can produce a 5-byte output, but we
only allocated 2 bytes). I expect that malloc overheads absorbed the
overrun in practice, but computing a correct upper bound is a very simple
change.
