* closes bpo-34585: Don't do runtime test to get float byte order. (GH-9085)Ross Burton2018-09-191-0/+3
| | | | | | | Currently configure.ac uses AC_RUN_IFELSE to determine the byte order of doubles, but this silently fails under cross compilation and Python doesn't do floats properly. Instead, steal a macro from autoconf-archive which compiles code using magic doubles (which encode to ASCII) and grep for the representation in the binary. RFC because this doesn't yet handle the weird ancient ARMv4 OABI 'mixed-endian' encoding properly. This encoding is ancient and I don't believe the union of "Python 3.8 users" and "OABI users" has anything in. Should the support for this just be dropped too? Alternatively, someone will need to find an OABI toolchain to verify the encoding of the magic double.

| | | | This makes streamed zips compatible with MacOS Archive Utility and other applications.
* bpo-34582: Adds JUnit XML output for regression tests (GH-9210)Steve Dower2018-09-181-0/+1

* bpo-34623: Use XML_SetHashSalt in _elementtree (GH-9146)Christian Heimes2018-09-181-0/+2
| | | | | | | | | | The C accelerated _elementtree module now initializes hash randomization salt from _Py_HashSecret instead of libexpat's default CPRNG. Signed-off-by: Christian Heimes <christian@python.org> https://bugs.python.org/issue34623
* bpo-33721: Make some os.path functions and pathlib.Path methods be tolerant ↵Serhiy Storchaka2018-09-181-0/+12
| | | | | | | | | | to invalid paths. (#7695) Such functions as os.path.exists(), os.path.lexists(), os.path.isdir(), os.path.isfile(), os.path.islink(), and os.path.ismount() now return False instead of raising ValueError or its subclasses UnicodeEncodeError and UnicodeDecodeError for paths that contain characters or bytes unrepresentative at the OS level.
* bpo-32455: Add jump parameter to dis.stack_effect(). (GH-6610)Serhiy Storchaka2018-09-182-0/+2
| | | | Add C API function PyCompile_OpcodeStackEffectWithJump().
* bpo-34589: Add -X coerce_c_locale command line option (GH-9378)Victor Stinner2018-09-181-0/+2
| | | | Add a new -X coerce_c_locale command line option to control C locale coercion (PEP 538).
* bpo-34589: C locale coercion off by default (GH-9073)Victor Stinner2018-09-171-0/+3
| | | | | | | | | Py_Initialize() and Py_Main() cannot enable the C locale coercion (PEP 538) anymore: it is always disabled. It can now only be enabled by the Python program ("python3). test_embed: get_filesystem_encoding() doesn't have to set PYTHONUTF8 nor PYTHONCOERCECLOCALE, these variables are already set in the parent.
* bpo-34587, test_socket: remove RDSTest.testCongestion() (GH-9277)Victor Stinner2018-09-171-0/+5
| | | | | | | | | The test tries to fill the receiver's socket buffer and expects an error. But the RDS protocol doesn't require that. Moreover, the Linux implementation of RDS expects that the producer of the messages reduces its rate, it's not the role of the receiver to trigger an error. The test fails on Fedora 28 by design, so remove it.
* bpo-32533: Fixed thread-safety of error handling in _ssl. (GH-7158)Steve Dower2018-09-171-0/+1

* bpo-34651: Only allow the main interpreter to fork. (gh-9279)Eric Snow2018-09-141-0/+3
| | | | | When os.fork() is called (on platforms that support it) all threads but the current one are destroyed in the child process. Consequently we must ensure that all but the associated interpreter are likewise destroyed. The main interpreter is critical for runtime operation, so we must ensure that fork only happens in the main interpreter. https://bugs.python.org/issue34651

* bpo-6721: Hold logging locks across fork() (GH-4071)Gregory P. Smith2018-09-141-0/+2
| | | | | | | | | bpo-6721: When os.fork() was called while another thread holds a logging lock, the child process may deadlock when it tries to log. This fixes that by acquiring all logging locks before fork and releasing them afterwards. A regression test that fails before this change is included. Within the new unittest itself: There is a small _potential_ due to mixing of fork and a thread in the child process if the parent's thread happened to hold a non-reentrant library call lock (malloc?) when the os.fork() happens. buildbots and time will tell if this actually manifests itself in this test or not. :/ A functionality test that avoids that would be a challenge. An alternate test that isn't trying to produce the deadlock itself but just checking that the release and acquire calls are made would be the next best alternative if so.

* bpo-34200: Fix non-determinism of test_pkg (GH-9248)Gregory P. Smith2018-09-131-0/+3

Our -fwrapv compiler flag and practical reasons why sets are unlikely to get this large should mean this was never an issue but it was incorrect code that generates code analysis warnings. <!-- issue-number: [bpo-1621](https://www.bugs.python.org/issue1621) --> https://bugs.python.org/issue1621 <!-- /issue-number -->
