* | bpo-35925: Skip SSL tests that fail due to weak external certs. (GH-13124)Gregory P. Smith2019-05-061-0/+1
| | | | | | | | | | | | | | | | Modern Linux distros such as Debian Buster have default OpenSSL system configurations that reject connections to servers with weak certificates by default. This causes our test suite run with external networking resources enabled to skip these tests when they encounter such a failure. Fixing the network servers is a separate issue.
* | bpo-36542: Allow to overwrite the signature for Python functions. (GH-12705)Serhiy Storchaka2019-05-061-0/+2

* | bpo-36793: Remove unneeded __str__ definitions. (GH-13081)Serhiy Storchaka2019-05-061-0/+3
| | | | | | | | Classes that define __str__ the same as __repr__ can just inherit it from object.
* | bpo-36594: Fix incorrect use of %p in format strings (GH-12769)Zackery Spytz2019-05-061-0/+2
|/ | | In addition, fix some other minor violations of C99.
* bpo-33530: Implement Happy Eyeballs in asyncio, v2 (GH-7237)twisteroid ambassador2019-05-051-0/+3
| | | | | | | | | | Added two keyword arguments, `delay` and `interleave`, to `BaseEventLoop.create_connection`. Happy eyeballs is activated if `delay` is specified. We now have documentation for the new arguments. `staggered_race()` is in its own module, but not exported to the main asyncio package. https://bugs.python.org/issue33530

| | | Use http.client.InvalidURL instead of ValueError as the new error case's exception.
* bpo-13611: C14N 2.0 implementation for ElementTree (GH-12966)Stefan Behnel2019-05-011-0/+2
| | | | | | | * Implement C14N 2.0 as a new canonicalize() function in ElementTree. Missing features: - prefix renaming in XPath expressions (tag and attribute text is supported) - preservation of original prefixes given redundant namespace declarations
* bpo-36676: Namespace prefix aware parsing support for the ET.XMLParser ↵Stefan Behnel2019-05-011-0/+3
| | | | | target (GH-12885) * bpo-36676: Implement namespace prefix aware parsing support for the XMLParser target in ElementTree.
* bpo-36673: Implement comment/PI parsing support for the TreeBuilder in ↵Stefan Behnel2019-05-011-0/+3
| | | | | | | | ElementTree. (#12883) * bpo-36673: Implement comment/PI parsing support for the TreeBuilder in ElementTree. * bpo-36673: Rewrite the comment/PI factory handling for the TreeBuilder in "_elementtree" to make it use the same factories as the ElementTree module, and to make it explicit when the comments/PIs are inserted into the tree and when they are not (which is the default).
* bpo-27682: Handle client connection terminations in wsgiref (GH-9713)Petter Strandmark2019-05-011-0/+2

* bpo-30458: Disallow control chars in http URLs. (GH-12755)Gregory P. Smith2019-05-011-0/+1
| | | Disallow control chars in http URLs in urllib.urlopen. This addresses a potential security problem for applications that do not sanity check their URLs where http request headers could be injected.
* bpo-36763: Fix Py_SetStandardStreamEncoding() (GH-13028)Victor Stinner2019-04-301-0/+2
| | | | Fix memory leak in Py_SetStandardStreamEncoding(): release memory if the function is called twice.
* Don't report deleted attributes in __dir__ (GH#10148)Mario Corchero2019-04-301-0/+2
| | | | | | When an attribute is deleted from a Mock, a sentinel is added rather than just deleting the attribute. This commit checks for such sentinels when returning the child mocks in the __dir__ method as users won't expect deleted attributes to appear when performing dir(mock).
* bpo-36742: Fixes handling of pre-normalization characters in urlsplit() ↵Steve Dower2019-04-301-0/+1

* bpo-34602: Avoid failures setting macOS stack resource limit (GH-13011)Ned Deily2019-04-291-0/+3
| | | | | | | | | | | | Under some conditions the earlier fix for bpo-18075, "Infinite recursion tests triggering a segfault on Mac OS X", now causes failures on macOS when attempting to change stack limit with resource.setrlimit resource.RLIMIT_STACK, like regrtest does when running the test suite. The reverted change had specified a non-default stack size when linking the python executable on macOS. As of macOS 10.14.4, the previous code causes a hard failure when running tests, although similar failures had been seen under some conditions under some earlier systems. For now, revert the original change and resume using the default stack size when linking the interpreter.

* bpo-36475: Finalize PyEval_AcquireLock() and PyEval_AcquireThread() properly ↵Joannah Nanjekye2019-04-291-0/+4
| | | | | | | | (GH-12667) PyEval_AcquireLock() and PyEval_AcquireThread() now terminate the current thread if called while the interpreter is finalizing, making them consistent with PyEval_RestoreThread(), Py_END_ALLOW_THREADS, and PyGILState_Ensure().
* bpo-21536: On Android, C extensions are linked to libpython (GH-12989)xdegaye2019-04-291-1/+1

* bpo-32424: Improve test coverage for xml.etree.ElementTree (GH-12891)Gordon P. Hemsley2019-04-282-0/+3
| | | | * Fix typo in test_cyclic_gc subtest * Improve test coverage for xml.etree.ElementTree
* bpo-36025: Fix PyDate_FromTimestamp API (GH-11922)Paul Ganssle2019-04-271-0/+5
| | | | | | | | | | | | | In the process of converting the date.fromtimestamp function to use argument clinic in GH-8535, the C API for PyDate_FromTimestamp was inadvertently changed to expect a timestamp object rather than an argument tuple. This PR fixes this backwards-incompatible change by adding a new wrapper function for the C API function that unwraps the argument tuple and passes it to the underlying function. This PR also adds tests for both PyDate_FromTimestamp and PyDateTime_FromTimestamp to prevent any further regressions.
* bpo-36722: Style and grammar edits for ABI news entries (GH-12979)Paul Ganssle2019-04-272-9/+10

* bpo-36719: regrtest always detect uncollectable objects (GH-12951)Victor Stinner2019-04-261-0/+4
| | | | | | | regrtest now always detects uncollectable objects. Previously, the check was only enabled by --findleaks. The check now also works with -jN/--multiprocess N. --findleaks becomes a deprecated alias to --fail-env-changed.
* bpo-36669: add matmul support to weakref.proxy (GH-12932)Mark Dickinson2019-04-261-0/+1
|
* bpo-36725: Refactor regrtest multiprocessing code (GH-12961)Victor Stinner2019-04-261-0/+3
| | | | | | | | | | | | | | | | Rewrite run_tests_multiprocess() function as a new MultiprocessRunner class with multiple methods to better report errors and stop immediately when needed. Changes: * Worker processes are now killed immediately if tests are interrupted or if a test does crash (CHILD_ERROR): worker processes are killed. * Rewrite how errors in a worker thread are reported to the main thread. No longer ignore BaseException or parsing errors silently. * Remove 'finished' variable: use worker.is_alive() instead * Always compute omitted tests. Add Regrtest.get_executed() method.
* bpo-36722: Debug build loads libraries built in release mode (GH-12952)Victor Stinner2019-04-251-0/+2
| | | | In debug build, import now also looks for C extensions compiled in release mode and for C extensions compiled in the stable ABI.
* bpo-35920: Windows 10 ARM32 platform support (GH-11774)Paul Monson2019-04-251-0/+3

* bpo-21536: C extensions are no longer linked to libpython (GH-12946)Victor Stinner2019-04-251-0/+12
| | | | | | | | | | | | | | On Unix, C extensions are no longer linked to libpython. It is now possible to load a C extension built using a shared library Python with a statically linked Python. When Python is embedded, libpython must not be loaded with RTLD_LOCAL, but RTLD_GLOBAL instead. Previously, using RTLD_LOCAL, it was already not possible to load C extensions which were not linked to libpython, like C extensions of the standard library built by the "*shared*" section of Modules/Setup. distutils, python-config and python-config.py have been modified.
* bpo-28552: Fix distutils.sysconfig for empty sys.executable (GH-12875)Victor Stinner2019-04-251-0/+4
| | | | | | | bpo-28552, bpo-7774: Fix distutils.sysconfig if sys.executable is None or an empty string: use os.getcwd() to initialize project_base. Fix also the distutils build command: don't use sys.executable if it's evaluated as false (None or empty string).
* bpo-36465: Make release and debug ABI compatible (GH-12615)Victor Stinner2019-04-241-0/+5
| | | | | | | | | | | | | | Release build and debug build are now ABI compatible: the Py_DEBUG define no longer implies Py_TRACE_REFS define which introduces the only ABI incompatibility. A new "./configure --with-trace-refs" build option is now required to get Py_TRACE_REFS define which adds sys.getobjects() function and PYTHONDUMPREFS environment variable. Changes: * Add ./configure --with-trace-refs * Py_DEBUG no longer implies Py_TRACE_REFS
* bpo-36668: FIX reuse semaphore tracker for child processes (#5172)Thomas Moreau2019-04-241-0/+1
| | | Fix the multiprocessing.semaphore_tracker so it is reused by child processes.
* bpo-30840: Document relative imports (#12831)Joannah Nanjekye2019-04-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | * document relative imports * 📜🤖 Added by blurb_it. * fix indentation error * remove indentation * Document relative imports * Document relative imports * remove from ...package * Document relative imports * remove trailing space * Document relative imports * Document relative imports
* bpo-36707: Remove the "m" flag (pymalloc) from SOABI (GH-12931)Victor Stinner2019-04-241-0/+3
| | | | | | "./configure --with-pymalloc" no longer adds the "m" flag to SOABI (sys.implementation.cache_tag). Enabling or disabling pymalloc has no impact on the ABI.
* bpo-36454: Fix test_time.test_monotonic() (GH-12929)Victor Stinner2019-04-231-0/+3
| | | | | Change test_time.test_monotonic() to test only the lower bound of elapsed time after a sleep command rather than the upper bound. This prevents unnecessary test failures on slow buildbots. Patch by Victor Stinner.
