* bpo-13487: Use sys.modules.copy() in inspect.getmodule() for thread safety. ↵Miss Islington (bot)2020-03-101-1/+1
| | | | | | | | | | | (GH-18786) `list(sys.modules.items())` was apparently not immune to "dictionary changed size during iteration" errors. Tested internally using an integration test that has run into this a couple of times in the past two years. With this patch applied, the test is no longer flaky.

* [3.7] bpo-39389: gzip: fix compression level metadata (GH-18077) (GH-18101)Miss Islington (bot)2020-03-042-3/+34
| | | | | | | | | | | | * bpo-39389: gzip: fix compression level metadata (GH-18077) As described in RFC 1952, section 2.3.1, the XFL (eXtra FLags) byte of a gzip member header should indicate whether the DEFLATE algorithm was tuned for speed or compression ratio. Prior to this patch, archives emitted by the `gzip` module always indicated maximum compression.

| | | | | | | | | | | | | | | | | | | | | | (GH-18725) Fix compileall.compile_dir() ddir= behavior on sub-packages. Fixes compileall.compile_dir's ddir parameter and compileall command line flag `-d` to no longer write the wrong pathname to the generated pyc file for submodules beneath the root of the directory tree being compiled. This fixes a regression introduced with Python 3.5. Tests backported from GH 02673352b5db6ca4d3dc804965facbedfe66425d, the implementation is different due to intervening code changes. But still quiet simple. Why was the bug ever introduced? The refactoring to add parallel execution kept the ddir -> dfile computations but discarded the results instead of sending them to compile_file(). This fixes that. Lack of tests meant this went unnoticed.. (cherry picked from commit ce720d3e0674d6ac6f1b950c20a89be4cfde7853) Co-authored-by: Gregory P. Smith <greg@krypto.org> [Google]

* Revert "bpo-27657: Fix urlparse() with numeric paths (GH-661)" (#18526)Senthil Kumaran2020-02-162-7/+25
| | | | | | | | | | | | | | | | | | | | | This reverts commit 82b5f6b16e051f8a2ac6e87ba86b082fa1c4a77f. The change broke the backwards compatibility of parsing behavior in a patch release of Python (3.7.6). A decision was taken to revert this patch in 3.7.7. In https://bugs.python.org/issue27657 it was decided that the previous behavior like >>> urlparse('localhost:8080') ParseResult(scheme='', netloc='', path='localhost:8080', params='', query='', fragment='') >>> urlparse('undefined:8080') ParseResult(scheme='', netloc='', path='undefined:8080', params='', query='', fragment='') needs to be preserved in patch releases as number of users rely upon it. Explicitly mention the releases involved with the revert in NEWS. Adopt the wording suggested by @ned-deily.
* bpo-39606: allow closing async generators that are already closed (GH-18475) ↵Nathaniel J. Smith2020-02-131-2/+28
| | | | | | | | | | | | | | | | (GH-18502) The fix for [bpo-39386](https://bugs.python.org/issue39386) attempted to make it so you couldn't reuse a agen.aclose() coroutine object. It accidentally also prevented you from calling aclose() at all on an async generator that was already closed or exhausted. This commit fixes it so we're only blocking the actually illegal cases, while allowing the legal cases. The new tests failed before this patch. Also confirmed that this fixes the test failures we were seeing in Trio with Python dev builds: https://github.com/python-trio/trio/pull/1396 https://bugs.python.org/issue39606 (cherry picked from commit 925dc7fb1d0db85dc137afa4cd14211bf0d67414)

| | | | | | | | | | | | | | | | | | | | Replace check for whether something is a method in the mock module. The previous version fails on PyPy, because there no method wrappers exist (everything looks like a regular Python-defined function). Thus the isinstance(getattr(result, '__get__', None), MethodWrapperTypes) check returns True for any descriptor, not just methods. This condition could also return erroneously True in CPython for C-defined descriptors. Instead to decide whether something is a method, just check directly whether it's a function defined on the class. This passes all tests on CPython and fixes the bug on PyPy.
