* bpo-28411: Support other mappings in PyInterpreterState.modules. (#3593)Eric Snow2017-09-151-8/+3
| | | | | The concrete PyDict_* API is used to interact with PyInterpreterState.modules in a number of places. This isn't compatible with all dict subclasses, nor with other Mapping implementations. This patch switches the concrete API usage to the corresponding abstract API calls. We also add a PyImport_GetModule() function (and some other helpers) to reduce a bunch of code duplication.
* bpo-28411: Isolate PyInterpreterState.modules (#3575)Eric Snow2017-09-141-28/+32
| | | | | A bunch of code currently uses PyInterpreterState.modules directly instead of PyImport_GetModuleDict(). This complicates efforts to make changes relative to sys.modules. This patch switches to using PyImport_GetModuleDict() uniformly. Also, a number of related uses of sys.modules are updated for uniformity for the same reason. Note that this code was already reviewed and merged as part of #1638. I reverted that and am now splitting it up into more focused parts.
* bpo-30860: Fix a refleak. (#3567)Eric Snow2017-09-141-1/+9
| | | | | Resolves bpo-31420. (This was accidentally reverted when in #3565.)
* bpo-31404: Revert "remove modules from Py_InterpreterState (#1638)" (#3565)Eric Snow2017-09-141-41/+35
| | | PR #1638, for bpo-28411, causes problems in some (very) edge cases. Until that gets sorted out, we're reverting the merge. PR #3506, a fix on top of #1638, is also getting reverted.

* bpo-30647: Check nl_langinfo(CODESET) in locale coercion (GH-2374)Nick Coghlan2017-06-291-8/+11
| | | | | | | | | | | | | - On some versions of FreeBSD, setting the "UTF-8" locale succeeds, but a subsequent "nl_langinfo(CODESET)" fails - adding a check for this in the coercion logic means that coercion will happen on systems where this check succeeds, and will be skipped otherwise - that way CPython should automatically adapt to changes in platform behaviour, rather than needing a new release to enable coercion at build time - this also allows UTF-8 to be re-enabled as a coercion target, restoring the locale coercion behaviour on Mac OS X
* bpo-30565: Add PYTHONCOERCECLOCALE=warn runtime flag (GH-2260)Nick Coghlan2017-06-181-25/+40
| | | | | | | | | | | | - removes PY_WARN_ON_C_LOCALE build time flag - locale coercion and compatibility warnings are now always compiled in, but are off by default - adds PYTHONCOERCECLOCALE=warn runtime option to aid in debugging potentially locale related compatibility problems Due to not-yet-resolved test failures on *BSD systems (including Mac OS X), this also temporarily disables UTF-8 as a locale coercion target, and skips testing the interpreter's behavior in the POSIX locale.
* bpo-28180: Implementation for PEP 538 (#659)Nick Coghlan2017-06-111-7/+167
| | | | | | | | | | - new PYTHONCOERCECLOCALE config setting - coerces legacy C locale to C.UTF-8, C.utf8 or UTF-8 by default - always uses C.UTF-8 on Android - uses `surrogateescape` on stdin and stdout in the coercion target locales - configure option to disable locale coercion at build time - configure option to disable C locale warning at build time
* bpo-30547: Fix multiple reference leaks (#1995)Stéphane Wirtel2017-06-081-1/+4

* bpo-22257: Small changes for PEP 432. (#1728)Eric Snow2017-05-231-5/+10
| | | PEP 432 specifies a number of large changes to interpreter startup code, including exposing a cleaner C-API. The major changes depend on a number of smaller changes. This patch includes all those smaller changes.

| | | | | is_valid_fd() now uses fstat() instead of dup() on macOS to return 0 on a pipe when the other side of the pipe is closed. fstat() fails with EBADF in that case, whereas dup() succeed.
