readline in all python versions is configured
to append a 'space' character for a successful
completion. But for almost all python expressions
'space' is not wanted (see coding conventions PEP 8).
For example if you have a function 'longfunction'
and you type 'longf<TAB>' you get 'longfunction '
as a completion. note the unwanted space at the
end.
The patch fixes this behaviour by setting readline's
append_character to '\0' which means don't append
anything. This doesn't work with readline < 2.1
(AFAIK nowadays readline2.2 is in good use).
An alternative approach would be to make the
append_character
accessable from python so that modules like
the rlcompleter.py can set it to '\0'.
[Ed.: I think expecting readline >= 2.2 is fine. If a completer wants
another character they can append that to the keyword in the list.]
[ 559250 ] more POSIX signal stuff
Adds support (and docs and tests and autoconfery) for posix signal
mask handling -- sigpending, sigprocmask and sigsuspend.
The old syntax suggested that a trailing comma was OK inside backticks,
but in fact (due to ideosyncrasies of pgen) it was not. Fix the grammar
to avoid the ambiguity. Fred: you may want to update the refman.
generations is now an array. This cleans up some code and makes it easy
to change the number of generations. Also, implemented a
gc_list_is_empty() function. This makes the logic a little clearer in
places. The performance impact of these changes should be negligible.
One functional change is that allocation/collection counters are always
zeroed at the start of a collection. This should fix SF bug #551915.
This change is too big for back-porting but the minimal patch on SF
looks good for a bugfix release.
Unicode objects are currently taken as binary data by the write()
method. This is not what Unicode users expect, nor what the
StringIO.py code does. Until somebody adds a way to specify binary or
text mode for cStringIO objects, change the format string to use "t#"
instead of "s#", so that it will request the "text buffer" version.
This will try the default encoding for Unicode objects.
This is *not* a 2.2 bugfix (since it *is* a semantic change).
don't understand how this function works, also beefed up the docs. The
most common usage error is of this form (often spread out across gotos):
if (_PyString_Resize(&s, n) < 0) {
Py_DECREF(s);
s = NULL;
goto outtahere;
}
The error is that if _PyString_Resize runs out of memory, it automatically
decrefs the input string object s (which also deallocates it, since its
refcount must be 1 upon entry), and sets s to NULL. So if the "if"
branch ever triggers, it's an error to call Py_DECREF(s): s is already
NULL! A correct way to write the above is the simpler (and intended)
if (_PyString_Resize(&s, n) < 0)
goto outtahere;
Bugfix candidate.
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.
and returns None. This allows any object that supports the fileno()
method to be passed as a file descriptor, not just an integer.
posix_fchdir(): New exposed function: implements posix.fchdir(). This
closes SF feature #536796.
posix_fsync(), posix_fdatasync(): Convert to use posix_fildes() instead
of posix_int(). This also changes them from METH_VARARGS to METH_O
functions.
setup_confname_table(): Remove unused variable. Change to take a module
rather than a dict to save the resulting table into.
setup_confname_tables(): Change to take a module instead of a dict to
pass to setup_confname_table().
PyMem_{Del, DEL} doesn't work yet (compilation problems).
pyport.h: _PyMem_EXTRA is gone.
pmem.h: Repaired comments. PyMem_{Malloc, MALLOC} and
PyMem_{Realloc, REALLOC} now make the same x-platform guarantees when
asking for 0 bytes, and when passing a NULL pointer to the latter.
object.c: PyMem_{Malloc, Realloc} just call their macro versions
now, since the latter take care of the x-platform 0 and NULL stuff
by themselves now.
pypcre.c, grow_stack(): So sue me. On two lines, this called
PyMem_RESIZE to grow a "const" area. It's not legit to realloc a
const area, so the compiler warned given the new expansion of
PyMem_RESIZE. It would have gotten the same warning before if it
had used PyMem_Resize() instead; the older macro version, but not the
function version, silently cast away the constness. IMO that was a wrong
thing to do, and the docs say the macro versions of PyMem_xyz are
deprecated anyway. If somebody else is resizing const areas with the
macro spelling, they'll get a warning when they recompile now too.
compatibility function.
Make PyObject_GC_Track and PyObject_GC_UnTrack functions instead of
trivial macros wrapping functions. Provide binary compatibility
functions.
Change pickling format for bools to use a backwards compatible
encoding. This means you can pickle True or False on Python 2.3
and Python 2.2 or before will read it back as 1 or 0. The code
used for pickling bools before would create pickles that could
not be read in previous Python versions.
PEP 285. Everything described in the PEP is here, and there is even
some documentation. I had to fix 12 unit tests; all but one of these
were printing Boolean outcomes that changed from 0/1 to False/True.
(The exception is test_unicode.py, which did a type(x) == type(y)
style comparison. I could've fixed that with a single line using
issubtype(x, type(y)), but instead chose to be explicit about those
places where a bool is expected.
Still to do: perhaps more documentation; change standard library
modules to return False/True from predicates.
457466: popenx() argument mangling hangs python
226766: popen('python -c"...."') tends to hang
Fixes argument quoting in w9xpopen.exe for Windows 9x. w9xpopen.exe
also never attempts to display a MessageBox when not executed
interactively.
Added test_popen() test. This test currently just executes
"python -c ..." as a child process, and checks that the expected
arguments were all recieved correctly by the child process. This
test succeeds for me on Win9x, win2k and Linux, and I hope it does
for other popen supported platforms too :)
Convert METH_OLDARGS -> METH_VARARGS: also PyArg_Parse -> PyArg_ParseTuple
Convert METH_OLDARGS -> METH_NOARGS: remove args parameter
Please review. All tests pass, but some modules don't have tests.
I spot checked various functions to try to make sure nothing broke.
The fix makes it possible to call PyObject_GC_UnTrack() more than once
on the same object, and then move the PyObject_GC_UnTrack() call to
*before* the trashcan code is invoked.
BUGFIX CANDIDATE!
Another year in the quest to out-guess random C behavior.
Added macros Py_ADJUST_ERANGE1(X) and Py_ADJUST_ERANGE2(X, Y). The latter
is useful for functions with complex results. Two corrections to errno-
after-libm-call are attempted:
1. If the platform set errno to ERANGE due to underflow, clear errno.
Some unknown subset of libm versions and link options do this. It's
allowed by C89, but I never figured anyone would do it.
2. If the platform did not set errno but overflow occurred, force
errno to ERANGE. C89 required setting errno to ERANGE, but C99
doesn't. Some unknown subset of libm versions and link options do
it the C99 way now.
Bugfix candidate, but hold off until some Linux people actually try it,
with and without -lieee. I'll send a help plea to Python-Dev.
The doc string for cStringIO suggested that str() of a StringIO object
was equivalent to getvalue(). This was never true, so repair the doc
string. (doctest would have helped here.)
Bug fix candidate for any past versions.
mmap_find_method(): this obtained the string to find via s#, but it
ignored its length, acting as if it were \0-terminated instead.
Someone please run on Linux too (the extended test_mmap works on Windows).
Bugfix candidate.
over SEP, ALTSEP and MAXPATHLEN.
Patched up posixmodule.c for MSVC, but unsure what the story is now on
other non-Unixish platforms -- the preprocessor maze has no exit <wink>.
Modules/
posixmodule.c
- use SEP,ALTSEP #defines instead of hard coded path separator chars
- use EMX specific variants of chdir2(),getcwd() that support drive letters
- OS/2+EMX spawnv(),spawnve() support
- EMX specific popen[234]() derived from Win32 popen[234]() code
socketmodule.c. No code outside of the .c file references it, so it
doesn't belong the .h file (at least not yet ...), and declaring it
an imported symbol in the .h file can't be made to work on Windows (it's
a cross-DLL symbol then) without substantial code rewriting. Also
repaired the comment that goes along with the decl, to stop referring
to names and functions that haven't existed for 7 years <wink>.
socketmodule.c compiles cleanly on Windows again. The test_socket dies
at once, though (later).
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).
[ #510644 ] test_curses segfaults
If we use the *object* *allocator*, we should use the *object* *deallocator*,
not the *raw memory* deallocator (confused yet?).
I think this was what caused segfaults when pymalloc was enabled.
Even if it wasn't the cause, it's still wrong.
2.2.1 candidate.
[ #504284 ] Last build problems on AIX
I'm ignoring the suggestion that this should be an autoconf test in the
interests of having a fix today. Feel free to quibble.
new.instancemethod() -- the instancemethod object is now a perfectly
general container.
This fixes SF bug ##503091 (Pedro Rodriquez): new.instancemethod fails
for new classes
This is a 2.2.1 candidate.
