* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-1265-95/+102
| | | | | | | | | | | | | | Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h
* bpo-33695 shutil.copytree() + os.scandir() cache (#7874)Giampaolo Rodola2018-11-123-56/+96

* Update subprocess.Popen documentation wrt universal_newlines arg (GH-10337)Jakub Stasiak2018-11-121-3/+8
| | | | | | | | * universal_newlines defaulting to False would suggest, that not specifying universal_newlines explicitly and setting text to True should cause an error, which is not the case. * The run function didn't have the universal_newlines parameter documented * The check_output function didn't have its text parameter documented
* bpo-33878: Doc: Fix missing case by simplifying. (GH-7762)Julien Palard2018-11-111-6/+3
| | | | | The documentation was not covering multiple targets enclosed by parenthesis nor multiple targets enclosed by brackets, adding them all would be heavy, an else cover them all and is lighter to read.
* bpo-35177: Add dependencies between header files (GH-10361)Victor Stinner2018-11-1113-26/+42
| | | | | | | | | | | | | | * ast.h now includes Python-ast.h and node.h * parsetok.h now includes node.h and grammar.h * symtable.h now includes Python-ast.h * Modify asdl_c.py to enhance Python-ast.h: * Add #ifndef/#define Py_PYTHON_AST_H to be able to include the header twice * Add "extern { ... }" for C++ * Undefine "Yield" macro conflicting with winbase.h * Remove "#undef Yield" from C files, it's now done in Python-ast.h * Remove now useless includes in C files
* closes bpo-35204: Disable thread and memory sanitizers for ↵Alexey Izbyshev2018-11-111-12/+31
| | | | | | | | | address_in_range(). (GH-10442) This function may access memory which is mapped but is considered free by libc allocator. It behaves so by design, therefore we need to suppress sanitizer reports. GCC doesn't support MSan, so disable only TSan for it.
* Neaten the code without any algorithmic change. (GH-10466)Raymond Hettinger2018-11-111-5/+2
| | | Remove unneeded assertion (we already know so is a PySetObject *).
* bpo-33699: Describe try's else clause with the rest of the try clause (GH-7252)Andrés Delfino2018-11-111-7/+5

* dict insertion order is guaranteed since 3.7 (GH-10431)Andrés Delfino2018-11-111-1/+1

* bpo-34864: Document two IDLE on MacOS issues. (GH-10456)Terry Jan Reedy2018-11-113-13/+37
| | | | | 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 Lib directory. (GH-10446)Srinivas Thatiparthy (శ్రీనివాస్ తాటిపర్తి)2018-11-107-9/+0

* Doc: Simplify Copyright line in README (GH-10287)David Kleuker2018-11-101-6/+2
| | | | | | | This also makes it consistent with other places like: - https://docs.python.org/dev/copyright.html - https://www.python.org/ footer - https://github.com/python/cpython/blob/e42b705188271da108de42b55d9344642170aa2b/Python/getcopyright.c#L7
* Correct a typo in the Unittest documentation (GH-10397)Géry Ogam2018-11-091-1/+1

* bpo-35199: Add an internal _PyTuple_ITEMS() macro (GH-10434)Victor Stinner2018-11-099-23/+27
| | | | | | | * _PyTuple_ITEMS() gives access to the tuple->ob_item field and cast the first argument to PyTupleObject*. This internal macro is only usable if Py_BUILD_CORE is defined. * Replace &PyTuple_GET_ITEM(ob, 0) with _PyTuple_ITEMS(ob). * Replace PyTuple_GET_ITEM(op, 1) with &_PyTuple_ITEMS(ob)[1].
* bpo-35081: Internal headers require Py_BUILD_CORE (GH-10363)Victor Stinner2018-11-0916-13/+48
| | | | | | | | | * All internal header files now require Py_BUILD_CORE or Py_BUILD_CORE_BUILTIN to be defined. * _json.c is now compiled with Py_BUILD_CORE_BUILTIN to access pycore_accu.h header. * Add an example to Modules/Setup to show how to build _json as a built-in module; it requires non trivial compiler options.
* Hoist the float conversion out of the inner loop. (GH-10430)Raymond Hettinger2018-11-091-1/+2
| | | Currently, the *n* and *total* variables get converted to floats each time they are multiplied by random(). This minor tweak does the conversion just once and gets a small speedup (approx 3%).
* Optimize set.pop() to advance a pointer instead of indexing. (GH-10429)Raymond Hettinger2018-11-091-7/+8
| | | | | Gives approx 20% speed-up using clang depending on the number of elements in the set (the less dense the set, the more the speed-up). Uses the same entry++ logic used elsewhere in the setobject.c code.
* Cleanup and improve the regex tokenizer example. (GH-10426)Raymond Hettinger2018-11-091-36/+38
| | | | | | | | | | | 1) Convert weird field name "typ" to the more standard "type". 2) For the NUMBER type, convert the value to an int() or float(). 3) Simplify ``group(kind)`` to the shorter and faster ``group()`` call. 4) Simplify logic go a single if-elif chain to make this easier to extend. 5) Reorder the tests to match the order the tokens are specified. This isn't necessary for correctness but does make the example easier to follow. 6) Move the "column" calculation before the if-elif chain so that users have the option of using this value in error messages.
* Fixing wording in comment. (GH-10425)Raymond Hettinger2018-11-091-1/+1
| | | | Since the n==1 case just returns *max*, it cannot be larger than the magnitude of the vector entry.
* bpo-35194: Fix a wrong constant in cp932 codec (GH-10420)Alexey Izbyshev2018-11-091-1/+1
| | | | | | | | | | | This typo doesn't affect the result because wrong bits are discarded on implicit conversion to unsigned char, but it trips UBSan with -fsanitize=implicit-integer-truncation. https://bugs.python.org/issue35194
* bpo-24412: Adds cleanUps for setUpClass and setUpModule. (GH-9190)Lisa Roach2018-11-097-18/+783

* bpo-35193: Fix an off by one error in the RETURN_VALUE case. (GH-10418)Gregory P. Smith2018-11-093-10/+34
| | | | | | | | | | | | 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 Michel2018-11-084-11/+26
| | | | | 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.
* Replace dead code with an assertion in winreg.c. (GH-10028)Zackery Spytz2018-11-081-2/+1

* bpo-34966: Improve support of method aliases in pydoc. (GH-9823)Serhiy Storchaka2018-11-083-4/+104
| | | | Pydoc now does not duplicate docstrings for aliases of inherited methods.
* Revert "bpo-32409: Fix regression in activate.bat on international Windows ↵Pablo Galindo2018-11-072-7/+6
| | | | | (GH-10295)" (GH-10403) This reverts commit c64583b6d3e8516a8cd2b5f84fc1e300bfac2206 due to multiple buildbot failures when building it.
* Doc: Make all versions sidebars the same for consistency. (GH-10288)Julien Palard2018-11-071-2/+3

* Fix the construction of subprocess.CalledProcessError in test_venv (GH-10400)Pablo Galindo2018-11-071-1/+1
| | | The constructor of subprocess.CalledProcessError in the check_output function had an extra None in it.

* bpo-34726: Fix handling of hash-based pycs in zipimport. (GH-10327)Elvis Pranskevichus2018-11-074-1049/+1147
| | | | | | | | 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.
* Add link to PEP 525 in Expressions. (GH-10333)Andrés Delfino2018-11-071-1/+5

* bpo-32409: Fix regression in activate.bat on international Windows (GH-10295)samstagern2018-11-072-6/+7
| | | | | | | | | | | 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-34898: Add mtime parameter to gzip.compress(). (GH-9704)guoci2018-11-076-4/+27
| | | | | 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.
