| | | | | | | | | (GH-15320) (GH-15456) Fix compilation of "break" and "continue" in the "finally" block when the corresponding "try" block contains "return" with a non-constant value. (cherry picked from commit ef61c524ddeeb56da3858b86e349e7288d68178e)

* bpo-36763: PyConfig_Read() handles PySys_AddXOption() (GH-15431) (GH-15435)Victor Stinner2019-08-232-31/+46
| | | | | | | | | | | | PyConfig_Read() is now responsible to handle early calls to PySys_AddXOption() and PySys_AddWarnOption(). Options added by PySys_AddXOption() are now handled the same way than PyConfig.xoptions and command line -X options. For example, PySys_AddXOption(L"faulthandler") enables faulthandler as expected.

* bpo-37549: os.dup() fails for standard streams on Windows 7 (GH-15389)Miss Islington (bot)2019-08-231-1/+8

* bpo-37926: Fix PySys_SetArgvEx(0, NULL, 0) crash (GH-15415) (GH-15420)Victor Stinner2019-08-231-1/+2
| | | | | | | | | | | | empty_argv is no longer static in Python 3.8, but it is declared in a temporary scope, whereas argv keeps a reference to it. empty_argv memory (allocated on the stack) is reused by make_sys_argv() code which is inlined when using gcc -O3. Define empty_argv in PySys_SetArgvEx() body, to ensure that it remains valid for the whole lifetime of the PySys_SetArgvEx() call. (cherry picked from commit c48682509dc49b43fe914fe6c502bc390345d1c2)
* bpo-37834: Normalise handling of reparse points on Windows (GH-15370)Steve Dower2019-08-211-1/+6
| | | | | | | | | | bpo-37834: Normalise handling of reparse points on Windows * ntpath.realpath() and nt.stat() will traverse all supported reparse points (previously was mixed) * nt.lstat() will let the OS traverse reparse points that are not name surrogates (previously would not traverse any reparse point) * nt.[l]stat() will only set S_IFLNK for symlinks (previous behaviour) * nt.readlink() will read destinations for symlinks and junction points only bpo-1311: os.path.exists('nul') now returns True on Windows * nt.stat('nul').st_mode is now S_IFCHR (previously was an error)

* [3.8] bpo-32912: Revert SyntaxWarning on invalid escape sequences (GH-15142)Serhiy Storchaka2019-08-091-3/+3
| | | | | | | * bpo-32912: Revert warnings for invalid escape sequences. DeprecationWarning will continue to be emitted for invalid escape sequences in string and bytes literals in 3.8 just as it did in 3.7. SyntaxWarning may be emitted in the future. But per mailing list discussion, we don't yet know when because we haven't settled on how to do so in a non-disruptive manner.
