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-34588: Fix an off-by-one error in traceback formatting. (GH-9077)Miss Islington (bot)2018-09-101-14/+16
| | | | | | | | | | | The recursive frame pruning code always undercounted the number of elided frames by one. That is, in the "[Previous line repeated N more times]" message, N would always be one too few. Near the recursive pruning cutoff, one frame could be silently dropped. That situation is demonstrated in the OP of the bug report. The fix is to start the identical frame counter at 1.

* [3.7] bpo-34485: stdout uses surrogateescape on POSIX locale (GH-8986) (GH-8987)Victor Stinner2018-08-291-12/+34
| | | | | | | | | | | | | | | * bpo-34485: stdout uses surrogateescape on POSIX locale (GH-8986) Standard streams like sys.stdout now use the "surrogateescape" error handler, instead of "strict", on the POSIX locale (when the C locale is not coerced and the UTF-8 Mode is disabled). Add tests on sys.stdout.errors with LC_ALL=POSIX. Fix the error handler of standard streams like sys.stdout: PYTHONIOENCODING=":" is now ignored instead of setting the error handler to "strict".

| | | | | | | | | | * _Py_InitializeCore() now sets the LC_CTYPE locale to the user preferred locale before checking if the C locale should be coerced or not in _PyCoreConfig_Read(). * Fix pymain_read_conf(): remember if the C locale has been coerced when the configuration should be read again if the encoding has changed.

| | | | | | | | | | | | * The UTF-8 Mode is now also enabled by the "POSIX" locale, not only by the "C" locale. * On FreeBSD, Py_DecodeLocale() and Py_EncodeLocale() now also forces the ASCII encoding if the LC_CTYPE locale is "POSIX", not only if the LC_CTYPE locale is "C". * test_utf8_mode.test_cmd_line() checks also that the command line arguments are decoded from UTF-8 when the the UTF-8 Mode is enabled with POSIX locale or C locale.

| | | | | | | | | | | | | | Historically, -m added the empty string as sys.path zero, meaning it resolved imports against the current working directory, the same way -c and the interactive prompt do.
