* bpo-35081: Make some _PyGC macros internal (GH-10507)Victor Stinner2018-11-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | * Move "GC" macros together: * PyObject_IS_GC() * _Py_AS_GC() * _PyObject_GC_IS_TRACKED() * _PyObject_GC_MAY_BE_TRACKED() * Mark other GC macros as internal (#ifdef Py_BUILD_CORE): * _PyGCHead_NEXT(g), _PyGCHead_SET_NEXT(g, p) * _PyGCHead_PREV(g), _PyGCHead_SET_PREV(g, p) * _PyGCHead_FINALIZED(g), _PyGCHead_SET_FINALIZED(g) * _PyGC_FINALIZED(o), _PyGC_SET_FINALIZED(o) * _PyObject_GC_TRACK(o), _PyObject_GC_UNTRACK(o) * _PyGC_PREV_MASK_FINALIZED * _PyGC_PREV_MASK_COLLECTING * _PyGC_PREV_SHIFT * _PyGC_PREV_MASK * Replace _PyGC_generation0 with _PyRuntime.gc.generation0 * _queuemodule.c: replace _PyObject_GC_UNTRACK() with with PyObject_GC_UnTrack() * Document that _PyObject_GC_TRACK() _PyObject_GC_UNTRACK() macros have been removed from the public C API.
* bpo-29564: warnings suggests to enable tracemalloc (GH-10486)Victor Stinner2018-11-131-0/+3
| | | | | The warnings module now suggests to enable tracemalloc if the source is specified, tracemalloc module is available, but tracemalloc is not tracing memory allocations.
* bpo-35214: Initial clang MemorySanitizer support (GH-10479)Gregory P. Smith2018-11-121-0/+4
| | | | | | | | | | Adds configure flags for msan and ubsan builds to make it easier to enable. These also encode the detail that address sanitizer and memory sanitizer should disable pymalloc. Define MEMORY_SANITIZER when appropriate at build time and adds workarounds to existing code to mark things as initialized where the sanitizer is otherwise unable to determine that. This lets our build succeed under the memory sanitizer. not all tests pass without sanitizer failures yet but we're in pretty good shape after this.

* bpo-34864: Document two IDLE on MacOS issues. (GH-10456)Terry Jan Reedy2018-11-111-0/+3
| | | | | The System Preferences Dock "prefer tabs always" setting disables some IDLE features. Menus are a bit different than as described for Windows and Linux.
* bpo-35202: Remove unused imports in idlelib (GH-10438)Srinivas Thatiparthy (శ్రీనివాస్ తాటిపర్తి)2018-11-101-0/+1
|
* bpo-24412: Adds cleanUps for setUpClass and setUpModule. (GH-9190)Lisa Roach2018-11-091-0/+4
|
* bpo-35193: Fix an off by one error in the RETURN_VALUE case. (GH-10418)Gregory P. Smith2018-11-091-0/+3
| | | | | | | | | | | | Fix an off by one error in the peephole optimizer when checking for unreachable code beyond a return. Do a bounds check within find_op so it can return before going past the end as a safety measure. https://github.com/python/cpython/commit/7db3c488335168993689ddae5914a28e16188447#diff-a33329ae6ae0bb295d742f0caf93c137 introduced this off by one error while fixing another one nearby. This bug was shipped in all Python 3.6 and 3.7 releases. The included unittest won't fail unless you do a clang msan build.
* bpo-35065: Remove `StreamReaderProtocol._untrack_reader` (#10212)Vincent Michel2018-11-081-0/+3
| | | | | The call to `_untrack_reader` is performed too soon, causing the protocol to forget about the reader before `connection_lost` can run and feed the EOF to the reader. See bpo-35065.
* bpo-34966: Improve support of method aliases in pydoc. (GH-9823)Serhiy Storchaka2018-11-081-0/+3
| | | | Pydoc now does not duplicate docstrings for aliases of inherited methods.
* Revert "bpo-32409: Fix regression in activate.bat on international Windows ↵Pablo Galindo2018-11-071-2/+0
| | | | | (GH-10295)" (GH-10403) This reverts commit c64583b6d3e8516a8cd2b5f84fc1e300bfac2206 due to multiple buildbot failures when building it.
* bpo-34726: Fix handling of hash-based pycs in zipimport. (GH-10327)Elvis Pranskevichus2018-11-071-0/+2
| | | | | | | | Current support for hash-based bytecode files in `zipimport` is rather sparse, which leads to test failures when the test suite is ran with the ``SOURCE_DATE_EPOCH`` environment variable set. This teaches zipimport to handle hash-based pycs properly.
* bpo-32409: Fix regression in activate.bat on international Windows (GH-10295)samstagern2018-11-071-0/+2
| | | | | | | | | | | Handle Unicode contents on localised Windows systems when activating a venv. activate.bat currently breaks on German Windows systems, as chcp.com does not return a plain number as on English systems, but (arbitrarily) appends a dot at the end (for example "Aktive Codepage: 850." instead of "Active Codepage: 850"). The dependency to chcp.com is removed and ctypes is used to get, set and restore the console output code page. The code page for console input is not changed. We can't use __VENV_PYTHON__ to find python.exe, since it's UTF-8. cmd.exe decodes the script using the console output code page.
* bpo-2504: Add pgettext() and variants to gettext. (GH-7253)Cheryl Sabella2018-11-072-0/+2
|
* bpo-34160: Preserve order of attributes in minidom. (GH-10219)Diego Rojas2018-11-071-1/+1

* bpo-31553: add --json-lines option to json.tool (#10051)HongWeipeng2018-11-071-0/+1
| | | | | | | | | | * add jsonlines option to json.tool * code review * fix:avoid read infile after it close * improve doc in whatsnew 3.8
* bpo-34898: Add mtime parameter to gzip.compress(). (GH-9704)guoci2018-11-072-0/+3
| | | | | Without setting mtime, time.time() will be used as the timestamp which will end up in the compressed data and each invocation of the compress() function will vary over time.
* bpo-33000: Document that IDLE's shell has no line limit. (#10373)Terry Jan Reedy2018-11-071-0/+2
| | | A program that runs indefinitely can overfill memory.
* bpo-17560: Too small type for struct.pack/unpack in ↵Alexander Buchkovsky2018-11-061-0/+1
| | | | | mutliprocessing.Connection (GH-10305) Allow sending more than 2 GB at once on a multiprocessing connection on non-Windows systems.
* bpo-23220: Explain how IDLE's Shell displays output (GH-10356)Terry Jan Reedy2018-11-061-0/+1
| | | Add a new subsection to the doc.
* bpo-35099: Improve the doc about IDLE running user code. (#10350)Terry Jan Reedy2018-11-061-0/+3
| | | | | The section is renamed from "IDLE -- console differences". It mostly covers the implications of using custom sys.stdxxx objects.
* bpo-33462: Add __reversed__ to dict and dict views (GH-6827)Rémi Lapeyre2018-11-061-0/+1
|
* bpo-32512: Add -m option to profile for profiling modules (#5132)Mario Corchero2018-11-051-0/+2
| | | | | | | | | The new option in the CLI of the profile module allow to profile executable modules. This change follows the same implementation as the one already present in `cProfile`. As the argument is now present on both modules, move the tests to the common test case to be run with profile as well.
* closes bpo-32285: Add unicodedata.is_normalized. (GH-4806)Max Bélanger2018-11-041-0/+2

* bpo-21263: Skip test_gdb when python has been compiled with LLVM clang ↵Lysandros Nikolaou2018-11-042-0/+5
| | | | (GH-10318)
* bpo-34969: Add --fast, --best on the gzip CLI (GH-9833)Stéphane Wirtel2018-11-031-0/+3
|
* bpo-29341: Clarify that path-like objects are accepted in some os methods ↵BNMetrics2018-11-021-0/+2
| | | | | (GH-10101) Some methods in the os module can accept path-like objects. This is documented in the general documentation but not in the function docstrings. To keep both in sync, the docstrings need to be updated to reflect that path-like objects are also accepted.
* closes bpo-35139: The `pyexpat` module's macros in `Modules/Setup` now match ↵Max Bélanger2018-11-021-0/+1
| | | | | `setup.py` (GH-10289) This could cause compile errors on macOS or other platforms.
* bpo-33578: Add getstate/setstate for CJK codec (GH-6984)Christopher Thorne2018-11-012-0/+2
| | | | | | | | This implements getstate and setstate for the cjkcodecs multibyte incremental encoders/decoders, primarily to fix issues with seek/tell. The encoder getstate/setstate is slightly tricky as the "state" is pending bytes + MultibyteCodec_State but only an integer can be returned. The approach I've taken is to encode this data into a long, similar to how .tell() encodes a "cookie_type" as a long. https://bugs.python.org/issue33578
* bpo-35062: Fix parsing _io.IncrementalNewlineDecoder's *translate* argument. ↵Xiang Zhang2018-10-311-0/+2
| | | | | | (GH-10217) _io.IncrementalNewlineDecoder's initializer possibly assigns out-of-range value to the bitwise struct field.

* bpo-31680: Add curses.ncurses_version. (GH-4217)Serhiy Storchaka2018-10-301-0/+1
| | | | Use curses.ncurses_version for conditionally skipping a test.
* bpo-33237: Improve AttributeError message for partially initialized module. ↵Serhiy Storchaka2018-10-301-0/+1
| | | | (GH-6398)
* bpo-34876: Change the lineno of the AST for decorated function and class. ↵Serhiy Storchaka2018-10-301-0/+6
| | | | | | | (GH-9731) It was overridden by the lineno of the first decorator. Now it is the lineno of 'def' or 'class'.
* bpo-33331: Clean modules in the reversed order in PyImport_Cleanup(). (GH-6565)Serhiy Storchaka2018-10-291-0/+1
| | | | | | Modules imported last are now cleared first at interpreter shutdown. A newly imported module is moved to the end of sys.modules, behind modules on which it depends.
* bpo-35097: Add IDLE doc subsection explaining editor windows. (#10206)Terry Jan Reedy2018-10-291-0/+2
| | | Topics include opening, title and status bar, .py* extension, and running.
* bpo-35047, unittest.mock: Better error messages on assert_called_xxx ↵Petter Strandmark2018-10-282-0/+4
| | | | | | | failures (GH-10090) unittest.mock now includes mock calls in exception messages if assert_not_called, assert_called_once, or assert_called_once_with fails.
* Issue 35093: Document the IDLE document viewer in the IDLE doc. (#10195)Terry Jan Reedy2018-10-281-0/+2
| | | Add a paragraph in "Help and preferences", "Help sources" subsection.
* bpo-33234 Improve list() pre-sizing for inputs with known lengths (GH-9846)Pablo Galindo2018-10-281-0/+2
| | | | | | | | | | | | The list() constructor isn't taking full advantage of known input lengths or length hints. This commit makes the constructor pre-size and not over-allocate when the input size is known (the input collection implements __len__). One on the main advantages is that this provides 12% difference in memory savings due to the difference between overallocating and allocating exactly the input size. For efficiency purposes and to avoid a performance regression for small generators and collections, the size of the input object is calculated using __len__ and not __length_hint__, as the later is considerably slower.

* bpo-35088: Update idlelib.help.copy_string docstring (#10164)Terry Jan Reedy2018-10-281-0/+2
| | | We now use git and backporting instead of hg and forward merging.
* bpo-35087: Update idlelib help files for the current doc build. (GH-10162)Terry Jan Reedy2018-10-281-0/+2
| | | There is only one trivial change to idle.rst. Nearly all the changes to help.html are the elimination of chapter and section numbers on headers due to changes in the build system. help.py no longer requires header numbering.
* bpo-34751: improved hash function for tuples (GH-9471)jdemeyer2018-10-281-0/+4
