Possibly contentious: The first time s.next() yields StopIteration (for
a given map argument s) is the last time map() *tries* s.next(). That
is, if other sequence args are longer, s will never again contribute
anything but None values to the result, even if trying s.next() again
could yield another result. This is the same behavior map() used to have
wrt IndexError, so it's the only way to be wholly backward-compatible.
I'm not a fan of letting StopIteration mean "try again later" anyway.
to no longer insist that len(seq) be defined.

This is meant to be a model for how other functions of this ilk (max,
filter, etc) can be generalized similarly. Feel encouraged to grab your
favorite and convert it!
Note some cute consequences:
list(file) == file.readlines() == list(file.xreadlines())
list(dict) == dict.keys()
list(dict.iteritems()) = dict.items()
list(xrange(i, j, k)) == range(i, j, k)
The new test case demonstrates the bug. Be more careful in
symtable_resolve_free() to add a var to cells or frees only if it
won't be added under some other rule.
XXX Add new assertion that will catch this bug.
of ParserCreate().
Added assignment tests for the ordered_attributes and specified_attributes
values, similar to the checks for the returns_unicode attribute.
I know some people don't like this -- if it's really controversial,
I'll take it out again. (If it's only Alex Martelli who doesn't like
it, that doesn't count as "real controversial" though. :-)
That's why this is a separate checkin from the iterators stuff I'm
about to check in next.
The changes cause compilation failures in any file in the Python
installation lib directory to cause the install to fail. It looks
like compileall.py intended to behave this way, but a change to
py_compile.py and a separate bug defeated it.
Fixes SF bug #412436
This change affects the test suite, which contains several files that
contain intentional errors. The solution is to extend compileall.py
with the ability to skip compilation of selected files.
In the test suite, rename nocaret.py and test_future[3..7].py to start
with badsyntax_nocaret.py and badsyntax_future[3..7].py. Update the
makefile to skip compilation of these files. Update the tests to use
the name names for imports.
NB compileall.py is changed so that compile_dir() returns success only
if all recursive calls to compile_dir() also check success.
than from module pickletester. Using the latter turned out to cause
the test to break when invoked as "import test.test_pickle" or "import
test.autotest".
now raises NameError instead of UnboundLocalError, because the var in
question is definitely not local. (This affects test_scope.py)
Also update the recent fix by Ping using get_func_name(). Replace
tests of get_func_name() return value with call to get_func_desc() to
match all the other uses.
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.
http://sourceforge.net/tracker/index.php?func=detail&aid=415514&group_id=5470&atid=105470
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.
\CVS: ----------------------------------------------------------------------
discussion on python-dev. 'from mod import *' is still banned except
at the module level.
Fix value for special NOOPT entry in symtable. Initialze to 0 instead
of None, so that later uses of PyInt_AS_LONG() are valid. (Bug
reported by Donn Cave.)
replace local REPR macros with PyObject_REPR in object.h
* Removed func_hash and func_compare, so they can be treated as immutable
content-less objects (address hash and comparison)
* Added tests to that affect to test_funcattrs (also testing func_code
is writable)
* Reverse meaning of tests in test_opcodes which checked identical code
gets identical functions
no don't have to start with underscore.
- Add spaces after commas in argument lists.
- Only test dbhash if bsddb can be imported. (Wonder if there are
more like this?)
added test script and expected output file as well
this closes patch 103297.
__all__ attributes will be added to other modules without first submitting
a patch, just adding the necessary line to the test script to verify
more-or-less correct implementation.
(I realize that I didn't really test this, because all the tests
succeed, so verify() never raised an AssertionError -- but the test
suite still succeeds, so I'm not too worried.)

suite will also perform its tests in optimization mode.

A new C API PyObject_Unicode() is also provided.

__getattr__() method, which clearly (like the other methods) was
intended to pass the __getattr__() call on to the self.err object,
mistakenly returned getattr(self, self.err) rather than
getattr(self.err, attr). Since self.err is not a string, this always
raises a TypeError. Apparently that doesn't bother for the one
attribute for which __getattr__() is actually called ('__coerce__'),
but it broke the rich comparisons stuff that I'm trying to get into
shape, so I'm fixing this now. (I could also simply remove the
__getattr__() method, but fixing it seems more in the spirit of what
the ComparableException class is trying to do.)
in case the parameters are out of bounds and fixes error handling
for .count(), .startswith() and .endswith() for the case of
mixed string/Unicode objects.
This patch adds Python style index semantics to PyUnicode_Count()
indices (including the special handling of negative indices).
The patch is an extended version of patch #103249 submitted
by Michael Hudson (mwh) on SF. It also includes new test cases.

the wrong number of arguments or duplicate keyword arguments are supplied.
Comes with more tests for test_extcall.py and and an update to an error

uppercase strings also when the IGNORECASE flag is set (bug #128899)
(also added test cases for recently fixed bugs to the regression suite
-- or in other words, check in re_tests.py too...)
(bugs #115903, #115696)
This is based on a patch by Darrel Gallion. I'm not 100%
sure about this fix, but I haven't managed to come up with
any test case it cannot handle...
-- added some more docstrings
-- fixed typo in scanner class (#125531)
-- the multiline flag (?m) should't affect the \Z operator (#127259)
-- fixed non-greedy backtracking bug (#123769, #127259)
-- added sre.DEBUG flag (currently dumps the parsed pattern structure)
-- fixed a couple of glitches in groupdict (the #126587 memory leak
had already been fixed by AMK)
pid across threads (but in that case, it's still the same process, and so
still sharing the "template" cache in tempfile.py). Repaired that, and
added a new std test.
On Linux, someone please run that standalone with more files and/or more
threads; e.g.,
python lib/test/test_threadedtempfile.py -f 1000 -t 10
to run with 10 threads each creating (and deleting) 1000 temp files.
codec to test all charmap codec features.
As side-effect of moving the test codec into a new module, the encodings
package codec import mechanism is checked as well.
Wasn't built on Windows; not in config.c either.
Module init function missing DL_EXPORT magic.
test_xreadline output file obviously wrong (started w/ "test_xrl").
test program very unclear about what was expected.
variant that never needs to "search from the right".
Also fixed unlikely memory leak in get_line, if string size overflows INTMAX.
Also new std test test_bufio to make sure .readline() works.
the mapping dictionaries can now contain 1-n mappings, meaning
that character ordinals may be mapped to strings or Unicode object,
e.g. 0x0078 ('x') -> u"abc", causing the ordinal to be replaced by
the complete string or Unicode object instead of just one character.
Another feature introduced by the patch is that of mapping oridnals to
the emtpy string. This allows removing characters.
The patch is different from patch #103100 in that it does not cause a
performance hit for the normal use case of 1-1 mappings.

the urljoin() function, which exercises the urlparse() and urlunparse()
functions as side effects.
(Moshe, why did we have perfectly empty tests checked in for this?)
an empty keywords dictionary (via apply() or the extended call syntax),
the keywords dict should be ignored. If the keywords dict is not empty,
TypeError should be raised. (Between the restructuring of the call
machinery and this patch, an empty dict in this situation would trigger
a SystemError via PyErr_BadInternalCall().)
Added regression tests to detect errors for this.
codec to not apply Latin-1 mappings for keys which are not found
in the mapping dictionaries, but instead treat them as undefined
mappings.
The patch was originally written by Martin v. Loewis with some
additional (cosmetic) changes and an updated test script
by Marc-Andre Lemburg.
The standard codecs were recreated from the most current files
available at the Unicode.org site using the Tools/scripts/gencodec.py
tool.
This patch closes the bugs #116285 and #119960.
1. When running in verbose mode, if any test happens to pass, print
a warning that the apparent success may be bogus (stdout isn't
compared in verbose mode). Been fooled by that too often.
2. When a test fails because the expected stdout doesn't match the
actual stdout, print as much of stdout as did match before the
first failing write. Else we get failures of the form "expected
'a', got 'b'" and a glance at the expected output file shows
500 instances of 'a' -- no idea where it failed, and, as in #1,
trying to run in verbose mode instead doesn't help because
stdout isn't compared then.
Christmas present to myself: the bisect module didn't define what
happened if the new element was already in the list. It so happens
that it inserted the new element "to the right" of all equal elements.
Since it wasn't defined, among other bad implications it was a mystery
how to use bisect to determine whether an element was already in the
list (I've seen code that *assumed* "to the right" without justification).
Added new methods bisect_left and insort_left that insert "to the left"
instead; made the old names bisect and insort aliases for the new names
bisect_right and insort_right; beefed up docstrings to explain what
these actually do; and added a std test for the bisect module.
information from the Expat library that is not part of its public API.
Do not print this information as the format of the string may (and will)
change as Expat evolves.
Add additional tests to make sure the ParserCreate() function raises the
right exceptions on illegal parameters.
roundtrip(): Show the offending syntax tree when things break; this makes
it a little easier to debug the module by adding test cases.
(Still need better tests for this module, but there's not enough time
today.)
also test join method of 8-bit strings.
Also changed the test() function to (1) compare the types of the
expected and actual result, and (2) in verbose mode, print the repr()
of the output.
testAAA(),
testAAB(): Added checks that the results are right.
testTooManyDocumentElements(): Added code to actually test this.
testCloneElementDeep()
testCloneElementShallow(): Filled these in with test code.
_testCloneElementCopiesAttributes(),
_setupCloneElement(): Helper functions used with the other
testCloneElement*() functions.
testCloneElementShallowCopiesAttributes(): No longer a separate test;
_setupCloneElement() uses _testCloneElementCopiesAttributes() to
test that this is always done.
testNormalize(): Added to check Node.normalize().
When a method is called with no regular arguments and * args, defer
the first arg is subclass check until after the * args have been
expanded.
N.B. The CALL_FUNCTION implementation is getting really hairy; should
review it to see if it can be simplified.
-- fixed negative lookbehind to work correctly at the beginning
of the target string (bug #117242)
-- improved syntax check; you can no longer refer to a group
inside itself (bug #110866)
First, only report garbage that the GC cannot free. Second, only report
the number of objects found, not their repr(). People can dig deeper on
their own if they find a leak.
Let's hope this is correct (I'm not sure why the sys.platform would be
'Darwin1.2' rather than 'darwin1', which seems to be the convention).
Someone with Darwin please test this!
libm result is 0). Cautiously add a few libm exception test cases:
1. That exp(-huge) returns 0 without exception.
2. That exp(+huge) triggers OverflowError.
3. That sqrt(-1) raises ValueError specifically (apparently under glibc linked
with -lieee, it was raising OverflowError due to an accident of the way
mathmodule.c's CHECK() macro happened to deal with Infs and NaNs under gcc).
