fixes bug #414940, and redoes the fix for #129417 in a different way.
It also fixes a number of other problems with locale-specific formatting:
If there is leading or trailing spaces, then no grouping should be applied
in the spaces, and the total length of the string should not be changed
due to grouping.
Also added test case which works only if the en_US locale is available.
"%#x" % 0
blew up, at heart because C sprintf supplies a base marker if and only if
the value is not 0. I then fixed that, by tolerating C's inconsistency
when it does %#x, and taking away that *Python* produced 0x0 when
formatting 0L (the "long" flavor of 0) under %#x itself. But after talking
with Guido, we agreed it would be better to supply 0x for the short int
case too, despite that it's inconsistent with C, because C is inconsistent
with itself and with Python's hex(0) (plus, while "%#x" % 0 didn't work
before, "%#x" % 0L *did*, and returned "0x0"). Similarly for %#X conversion.

For short ints, Python defers to the platform C library to figure out what
%#x should do. The code asserted that the platform C returned a string
beginning with "0x". However, that's not true when-- and only when --the
*value* being formatted is 0. Changed the code to live with C's inconsistency
here. In the meantime, the problem does not arise if you format a long 0 (0L)
instead. However, that's because the code *we* wrote to do %#x conversions on
longs produces a leading "0x" regardless of value. That's probably wrong too:
we should drop leading "0x", for consistency with C, when (& only when) formatting
0L. So I changed the long formatting code to do that too.
catch IOError as well as OverflowError. I found that on Tru64 Unix
this was raised; probably because the OS (or libc) doesn't support
large files but the architecture is 64 bits!
bugs on sizeof(long)==8 machines. pickle.py has no idea what it's
doing with very large ints, and variously gets things right by accident,
computes nonsense, or generates corrupt pickles. cPickle fails on
cases 2**31 <= i < 2**32: since it *thinks* those are 4-byte ints
(the "high 4 bytes" are all zeroes), it stores them in the (signed!) BININT
format, so they get unpickled as negative values.
integers, but the std tests don't exercise most of them. Repair that.
CAUTION: I expect this to fail on boxes with sizeof(long)==8, in the
part of test_cpickle (but not test_pickle) trying to do a binary mode
(not text mode) load of the embedded BINDATA pickle string. Once that
hypothesized failure is confirmed, I'll fix cPickle.c.
This applies the patch Fred Drake created to fix it.
I'm checking it in since I had to apply the patch anyway in order
to test its behavior on Windows.
used by Jython. The tests in this module expect C locale, so be
explicit about setting that (for CPython). However, in Jython, there
is no C locale, so instead be explicit about setting the US locale.
Closes the patch.
#403666. Specifically,
In codestr, force `c' to be global. It's unclear what the semantics
should be for a code object compiled at module scope, but bound and
run in a function. In CPython, `c' is global (by accident?) while in
Jython, `c' is local. The intent of the test clearly is to make `c'
global, so let's be explicit about it.
Jython also does not have a __builtins__ name in the module's
namespace, so we use a more portable alternative (though I'm not sure
why the test requires "__builtins__" in the g namespace).
Finally, skip the new.code() test if the new module doesn't have a
`code' attribute. Jython will never have this.
This makes verbose-mode output easier to dig thru, and removes an accidental
dependence on the order of dict.items() (made visible by recent changes to
dictobject.c).
of another list comp. This caused crashes reported as SF bugs 409230
and 407800.
Note that the new tests are in a function so that the name lookup code
isn't affected by how many *other* list comprehensions are in the same
scope.
ZipFile.__del__() when there was an IOError opening the underlying
file in ZipFile.__init__().
This is an odd test: since the exception is in the __del__() method,
it is not propogated. This test will trigger it but regrtest.py
does not detect the failure (not sure why); we are dependent on it
actually being noticed by a user to get a new bug report if it ever
fails. ;-(
On the other hand, this makes sure that code gets exercised, so
a failure could be noticed!
compile.h: #define NESTED_SCOPES_DEFAULT 0 for Python 2.1
__future__ feature name: "nested_scopes"
symtable.h: Add st_nested_scopes slot. Define flags to track exec and
import star.
Lib/test/test_scope.py: requires nested scopes
compile.c: Fiddle with error messages.
Reverse the sense of ste_optimized flag on
PySymtableEntryObjects. If it is true, there is an optimization
conflict.
Modify get_ref_type to respect st_nested_scopes flags.
Refactor symtable_load_symbols() into several smaller functions,
which use struct symbol_info to share variables. In new function
symtable_update_flags(), raise an error or warning for import * or
bare exec that conflicts with nested scopes. Also, modify handle
for free variables to respect st_nested_scopes flag.
In symtable_init() assign st_nested_scopes flag to
NESTED_SCOPES_DEFAULT (defined in compile.h).
Add preliminary and often incorrect implementation of
symtable_check_future().
Add symtable_lookup() helper for future use.
- func.__dict__ is None until the first attribute is assigned
- del func.__dict__ is equivalent to func.__dict__ = None
- disallowing assignment to function attribute through unbound method
(it was always illegal to assign through bound method).
- verifying that setting attribute explicitly on underlying function
via meth.im_func is okay.
NamedNodeMap.setNamedItem(). Martin, should I sync the PyXML tree, too,
or do you want to do it? (I don't know if you're wrapping the 0.6.4
release right now.)
also modified check_all function to suppress all warnings since they aren't
relevant to what this test is doing (allows quiet checking of regsub, for
instance)
GNOME-style internationalized options can be parsed using ConfigParser
(SF bug #131635).
Converted the tests to use test_support.verify() instead of output
comparison to work.
run first. Indirectly due to Skip adding check_all("pty") to test___all__:
that caused the expected ImportError due to pty.py trying to import the
non-existent FCNTL to get handled by test___all__, leaving a partial
module object for pty in sys.modules, which caused the later import of
pty via test_pty to succeed. Then test_tpy died with an AttributeError,
due to trying to access attributes of pty that didn't exist. regrtest
viewed that as a failure rather than the appropriate "test skipped".
Fixed by deleting partial module objects in test___all__ when test___all__
handles an ImportError.
Guido told me to do this <wink>.
Greatly expanded docstrings, and fleshed out with examples.
New std test.
Added new get_close_matches() function for ESR.
Needs docs, but LaTeXification of the module docstring is all it needs.
