* Correct "inplace" with "in-place" (GH-10480)Andre Delfino2019-04-081-2/+2
|
* bpo-36157:Document PyInterpreterState_Main() (GH-12238)Joannah Nanjekye2019-04-011-0/+5
| | | | | | | I have added documentation for `PyInterpreterState_Main()`. I chose to place it under Advanced Debugger Support together with similar functions like `PyInterpreterState_Head()`, `PyInterpreterState_Next(`), and `PyInterpreterState_ThreadHead()` . https://bugs.python.org/issue36157
* bpo-20844: open script file with "rb" mode (GH-12616)Inada Naoki2019-04-011-0/+4

* bpo-31904: Add encoding support for VxWorks RTOS (GH-12051)pxinwr2019-03-042-6/+6
| | | | | | | | Use UTF-8 as the system encoding on VxWorks. The main reason are: 1. The locale is frequently misconfigured. 2. Missing some functions to deal with locale in VxWorks C library.
* Document the surprising sideeffect PyErr_Print(). (#12081)Gregory P. Smith2019-02-271-2/+6
| | | | | Did you know an API documented as printing the pending traceback would sometimes exit the process? You do now.
* bpo-36048: Use __index__() instead of __int__() for implicit conversion if ↵Serhiy Storchaka2019-02-252-12/+57
| | | | | | available. (GH-11952) Deprecate using the __int__() method in implicit conversions of Python numbers to C integers.
* Correct name of 'defaultobj' parameter in PyDict_SetDefault() signature. ↵Sergey Fedoseev2019-02-251-1/+1
| | | | (GH-11929)
* bpo-35224: PEP 572 Implementation (#10497)Emily Morehouse2019-01-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add tokenization of := - Add token to Include/token.h. Add token to documentation in Doc/library/token.rst. - Run `./python Lib/token.py` to regenerate Lib/token.py. - Update Parser/tokenizer.c: add case to handle `:=`. * Add initial usage of := in grammar. * Update Python.asdl to match the grammar updates. Regenerated Include/Python-ast.h and Python/Python-ast.c * Update AST and compiler files in Python/ast.c and Python/compile.c. Basic functionality, this isn't scoped properly * Regenerate Lib/symbol.py using `./python Lib/symbol.py` * Tests - Fix failing tests in test_parser.py due to changes in token numbers for internal representation * Tests - Add simple test for := token * Tests - Add simple tests for named expressions using expr and suite * Tests - Update number of levels for nested expressions to prevent stack overflow * Update symbol table to handle NamedExpr * Update Grammar to allow assignment expressions in if statements. Regenerate Python/graminit.c accordingly using `make regen-grammar` * Tests - Add additional tests for named expressions in RoundtripLegalSyntaxTestCase, based on examples and information directly from PEP 572 Note: failing tests are currently commented out (4 out of 24 tests currently fail) * Tests - Add temporary syntax test failure tests in test_parser.py Note: There is an outstanding TODO for this -- syntax tests need to be moved to a different file (presumably test_syntax.py), but this is covering what needs to be tested at the moment, and it's more convenient to run a single test for the time being * Add support for allowing assignment expressions as function argument annotations. Uncomment tests for these cases because they all pass now! * Tests - Move existing syntax tests out of test_parser.py and into test_named_expressions.py. Refactor syntax tests to use unittest * Add TargetScopeError exception to extend SyntaxError Note: This simply creates the TargetScopeError exception, it is not yet used anywhere * Tests - Update tests per PEP 572 Continue refactoring test suite: The named expression test suite now checks for any invalid cases that throw exceptions (no longer limited to SyntaxErrors), assignment tests to ensure that variables are properly assigned, and scope tests to ensure that variable availability and values are correct Note: - There are still tests that are marked to skip, as they are not yet implemented - There are approximately 300 lines of the PEP that have not yet been addressed, though these may be deferred * Documentation - Small updates to XXX/todo comments - Remove XXX from child description in ast.c - Add comment with number of previously supported nested expressions for 3.7.X in test_parser.py * Fix assert in seq_for_testlist() * Cleanup - Denote "Not implemented -- No keyword args" on failing test case. Fix PEP8 error for blank lines at beginning of test classes in test_parser.py * Tests - Wrap all file opens in `with...as` to ensure files are closed * WIP: handle f(a := 1) * Tests and Cleanup - No longer skips keyword arg test. Keyword arg test now uses a simpler test case and does not rely on an external file. Remove print statements from ast.c * Tests - Refactor last remaining test case that relied on on external file to use a simpler test case without the dependency * Tests - Add better description of remaning skipped tests. Add test checking scope when using assignment expression in a function argument * Tests - Add test for nested comprehension, testing value and scope. Fix variable name in skipped comprehension scope test * Handle restriction of LHS for named expressions - can only assign to LHS of type NAME. Specifically, restrict assignment to tuples This adds an alternative set_context specifically for named expressions, set_namedexpr_context. Thus, context is now set differently for standard assignment versus assignment for named expressions in order to handle restrictions. * Tests - Update negative test case for assigning to lambda to match new error message. Add negative test case for assigning to tuple * Tests - Reorder test cases to group invalid syntax cases and named assignment target errors * Tests - Update test case for named expression in function argument - check that result and variable are set correctly * Todo - Add todo for TargetScopeError based on Guido's comment (https://github.com/python/cpython/commit/2b3acd37bdfc2d35e5094228c6684050d2aa8b0a#r30472562) * Tests - Add named expression tests for assignment operator in function arguments Note: One of two tests are skipped, as function arguments are currently treating an assignment expression inside of parenthesis as one child, which does not properly catch the named expression, nor does it count arguments properly * Add NamedStore to expr_context. Regenerate related code with `make regen-ast` * Add usage of NamedStore to ast_for_named_expr in ast.c. Update occurances of checking for Store to also handle NamedStore where appropriate * Add ste_comprehension to _symtable_entry to track if the namespace is a comprehension. Initialize ste_comprehension to 0. Set set_comprehension to 1 in symtable_handle_comprehension * s/symtable_add_def/symtable_add_def_helper. Add symtable_add_def to handle grabbing st->st_cur and passing it to symtable_add_def_helper. This now allows us to call the original code from symtable_add_def by instead calling symtable_add_def_helper with a different ste. * Refactor symtable_record_directive to take lineno and col_offset as arguments instead of stmt_ty. This allows symtable_record_directive to be used for stmt_ty and expr_ty * Handle elevating scope for named expressions in comprehensions. * Handle error for usage of named expression inside a class block * Tests - No longer skip scope tests. Add additional scope tests * Cleanup - Update error message for named expression within a comprehension within a class. Update comments. Add assert for symtable_extend_namedexpr_scope to validate that we always find at least a ModuleScope if we don't find a Class or FunctionScope * Cleanup - Add missing case for NamedStore in expr_context_name. Remove unused var in set_namedexpr_content * Refactor - Consolidate set_context and set_namedexpr_context to reduce duplicated code. Special cases for named expressions are handled by checking if ctx is NamedStore * Cleanup - Add additional use cases for ast_for_namedexpr in usage comment. Fix multiple blank lines in test_named_expressions * Tests - Remove unnecessary test case. Renumber test case function names * Remove TargetScopeError for now. Will add back if needed * Cleanup - Small comment nit for consistency * Handle positional argument check with named expression * Add TargetScopeError exception definition. Add documentation for TargetScopeError in c-api docs. Throw TargetScopeError instead of SyntaxError when using a named expression in a comprehension within a class scope * Increase stack size for parser by 200. This is a minimal change (approx. 5kb) and should not have an impact on any systems. Update parser test to allow 99 nested levels again * Add TargetScopeError to exception_hierarchy.txt for test_baseexception.py_ * Tests - Major update for named expression tests, both in test_named_expressions and test_parser - Add test for TargetScopeError - Add tests for named expressions in comprehension scope and edge cases - Add tests for named expressions in function arguments (declarations and call sites) - Reorganize tests to group them more logically * Cleanup - Remove unnecessary comment * Cleanup - Comment nitpicks * Explicitly disallow assignment expressions to a name inside parentheses, e.g.: ((x) := 0) - Add check for LHS types to detect a parenthesis then a name (see note) - Add test for this scenario - Update tests for changed error message for named assignment to a tuple (also, see note) Note: This caused issues with the previous error handling for named assignment to a LHS that contained an expression, such as a tuple. Thus, the check for the LHS of a named expression must be changed to be more specific if we wish to maintain the previous error messages * Cleanup - Wrap lines more strictly in test file * Revert "Explicitly disallow assignment expressions to a name inside parentheses, e.g.: ((x) := 0)" This reverts commit f1531400ca7d7a2d148830c8ac703f041740896d. * Add NEWS.d entry * Tests - Fix error in test_pickle.test_exceptions by adding TargetScopeError to list of exceptions * Tests - Update error message tests to reflect improved messaging convention (s/can't/cannot) * Remove cases that cannot be reached in compile.c. Small linting update. * Update Grammar/Tokens to add COLONEQUAL. Regenerate all files * Update TargetScopeError PRE_INIT and POST_INIT, as this was purposefully left out when fixing rebase conflicts * Add NamedStore back and regenerate files * Pass along line number and end col info for named expression * Simplify News entry * Fix compiler warning and explicity mark fallthrough

| | | | | | | | PyUnicode_DecodeLocaleAndSize(), PyUnicode_DecodeLocale() and PyUnicode_EncodeLocale() now use always use the UTF-8 encoding on Android, instead of the current locale encoding. On Android API 19, mbstowcs() and wcstombs() are broken and cannot be used.
* bpo-29240: Fix locale encodings in UTF-8 Mode (#5170)Victor Stinner2018-01-152-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | Modify locale.localeconv(), time.tzname, os.strerror() and other functions to ignore the UTF-8 Mode: always use the current locale encoding. Changes: * Add _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx(). On decoding or encoding error, they return the position of the error and an error message which are used to raise Unicode errors in PyUnicode_DecodeLocale() and PyUnicode_EncodeLocale(). * Replace _Py_DecodeCurrentLocale() with _Py_DecodeLocaleEx(). * PyUnicode_DecodeLocale() now uses _Py_DecodeLocaleEx() for all cases, especially for the strict error handler. * Add _Py_DecodeUTF8Ex(): return more information on decoding error and supports the strict error handler. * Rename _Py_EncodeUTF8_surrogateescape() to _Py_EncodeUTF8Ex(). * Replace _Py_EncodeCurrentLocale() with _Py_EncodeLocaleEx(). * Ignore the UTF-8 mode to encode/decode localeconv(), strerror() and time zone name. * Remove PyUnicode_DecodeLocale(), PyUnicode_DecodeLocaleAndSize() and PyUnicode_EncodeLocale() now ignore the UTF-8 mode: always use the "current" locale. * Remove _PyUnicode_DecodeCurrentLocale(), _PyUnicode_DecodeCurrentLocaleAndSize() and _PyUnicode_EncodeCurrentLocale().
