Core and Builtins
|
||||
-----------------
|
||||
|
||||
- Issue #13703: oCERT-2011-003: add -R command-line option and PYTHONHASHSEED
|
||||
environment variable, to provide an opt-in way to protect against denial of
|
||||
service attacks due to hash collisions within the dict and set types. Patch
|
||||
by David Malcolm, based on work by Victor Stinner.
|
||||
|
||||
- Issue #14084: Fix a file descriptor leak when importing a module with a
|
||||
bad encoding.
|
||||
|
||||
- Issue #13020: Fix a reference leak when allocating a structsequence object
|
||||
fails. Patch by Suman Saha.

|
||||
modification time doesn't fit in a 32-bit timestamp.
|
||||
|
||||
- Fix the builtin module initialization code to store the init function for
|
||||
future reinitialization.
|
||||
|
||||
- Issue #8052: The posix subprocess module would take a long time closing
|
||||
all possible file descriptors in the child process rather than just open
|
||||
file descriptors. It now closes only the open fds if possible for the
|
||||
default close_fds=True behavior.
|
||||
|
||||
- Issue #13629: Renumber the tokens in token.h so that they match the indexes
|
||||
into _PyParser_TokenNames.
|
||||

|
||||
effect of appearing to resolve the issue. Thanks to Mark Shannon for
|
||||
noticing.
|
||||
|
||||

|
||||

|
||||
given by Campbell Barton).

||||
- Issue #7111: Python can now be run without a stdin, stdout or stderr
|
||||
stream. It was already the case with Python 2. However, the corresponding
|
||||
sys module entries are now set to None (instead of an unusable file object).
|
||||
|
||||
- Issue #13436: Fix a bogus error message when an AST object was passed
|
||||
an invalid integer value.
|
||||
|
||||
- Issue #13338: Handle all enumerations in _Py_ANNOTATE_MEMORY_ORDER
|
||||
to allow compiling extension modules with -Wswitch-enum on gcc.
|
||||
Initial patch by Floris Bruynooghe.
|
||||
|
||||
- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
|
||||
already accepts them).
|
||||
|
||||
- Issue #13342: input() used to ignore sys.stdin's and sys.stdout's unicode
|
||||

|
||||
variable in the default value of a keyword-only argument:
|
||||
(lambda *, arg=GLOBAL_NAME: None)

||||

||||
- Issue #10519: Avoid unnecessary recursive function calls in

setobject.c.

|
||||
interpreter would sometimes invoke the wrong metaclass when building a new
|
||||
class object. These cases now behave correctly. Patch by Daniel Urban.
|
||||
|
||||
- Issue #12604: VTRACE macro expanded to no-op in _sre.c to avoid compiler
|
||||
warnings. Patch by Josh Triplett and Petri Lehtinen.
|
||||
|
||||
- Issue #13188: When called without an explicit traceback argument,
|
||||
generator.throw() now gets the traceback from the passed exception's
|
||||
``__traceback__`` attribute. Patch by Petri Lehtinen.

||||

||||

|
||||
longer include a "manifest" to prevent them failing at import time in some
|
||||
embedded situations.
|
||||
|
||||
- Issue #13063: the Windows error ERROR_NO_DATA (numbered 232 and described
|
||||
as "The pipe is being closed") is now mapped to POSIX errno EPIPE
|
||||
(previously EINVAL).
|
||||
|
||||
- Issue #12911: Fix memory consumption when calculating the repr() of huge
|
||||
tuples or lists.
|
||||
|
||||
- Issue #7732: Don't open a directory as a file anymore while importing a
|
||||
module. Ignore the direcotry if its name matchs the module name (e.g.
|
||||
"__init__.py") and raise a ImportError instead.
|
||||
|
||||
- Issue #13021: Missing decref on an error path. Thanks to Suman Saha for

finding the bug and providing a patch.
|
||||
|
||||
- Issue #12973: Fix overflow checks that relied on undefined behaviour in
|
||||
list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These bugs
|
||||
caused test failures with recent versions of Clang.
|
||||
|
||||
- Issue #12802: the Windows error ERROR_DIRECTORY (numbered 267) is now
|
||||
mapped to POSIX errno ENOTDIR (previously EINVAL).
|
||||
|
||||

|
||||
characters even in narrow Unicode builds.

|
||||
an exception.

titlecased and cased non-letter characters.
