* bpo-35224: PEP 572 Implementation (#10497)Emily Morehouse2019-01-245-50/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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
* bpo-35713: Reorganize sys module initialization (GH-11658)Victor Stinner2019-01-231-3/+6
| | | | | | | | | * Rename _PySys_BeginInit() to _PySys_InitCore(). * Rename _PySys_EndInit() to _PySys_InitMain(). * Add _PySys_Create(). It calls _PySys_InitCore() which becomes private. * Add _PySys_SetPreliminaryStderr(). * Rename _Py_ReadyTypes() to _PyTypes_Init(). * Misc code cleanup.
* bpo-35713: Split _Py_InitializeCore into subfunctions (GH-11650)Victor Stinner2019-01-221-2/+3
| | | | | | | | | | | | | | * Split _Py_InitializeCore_impl() into subfunctions: add multiple pycore_init_xxx() functions * Preliminary sys.stderr is now set earlier to get an usable sys.stderr ealier. * Move code into _Py_Initialize_ReconfigureCore() to be able to call it from _Py_InitializeCore(). * Split _PyExc_Init(): create a new _PyBuiltins_AddExceptions() function. * Call _PyExc_Init() earlier in _Py_InitializeCore_impl() and new_interpreter() to get working exceptions earlier. * _Py_ReadyTypes() now returns _PyInitError rather than calling Py_FatalError(). * Misc code cleanup
* bpo-35713: Rework Python initialization (GH-11647)Victor Stinner2019-01-222-34/+32
| | | | | | | | | | | | | | | | | | | * The PyByteArray_Init() and PyByteArray_Fini() functions have been removed. They did nothing since Python 2.7.4 and Python 3.2.0, were excluded from the limited API (stable ABI), and were not documented. * Move "_PyXXX_Init()" and "_PyXXX_Fini()" declarations from Include/cpython/pylifecycle.h to Include/internal/pycore_pylifecycle.h. Replace "PyAPI_FUNC(TYPE)" with "extern TYPE". * _PyExc_Init() now returns an error on failure rather than calling Py_FatalError(). Move macros inside _PyExc_Init() and undefine them when done. Rewrite macros to make them look more like statement: add ";" when using them, add "do { ... } while (0)". * _PyUnicode_Init() now returns a _PyInitError error rather than call Py_FatalError(). * Move stdin check from _PySys_BeginInit() to init_sys_streams(). * _Py_ReadyTypes() now returns a _PyInitError error rather than calling Py_FatalError().
* bpo-33416: Add end positions to Python AST (GH-11605)Ivan Levkivskyi2019-01-222-115/+165
| | | | | | | | | | | | | | | | | | The majority of this PR is tediously passing `end_lineno` and `end_col_offset` everywhere. Here are non-trivial points: * It is not possible to reconstruct end positions in AST "on the fly", some information is lost after an AST node is constructed, so we need two more attributes for every AST node `end_lineno` and `end_col_offset`. * I add end position information to both CST and AST. Although it may be technically possible to avoid adding end positions to CST, the code becomes more cumbersome and less efficient. * Since the end position is not known for non-leaf CST nodes while the next token is added, this requires a bit of extra care (see `_PyNode_FinalizeEndPos`). Unless I made some mistake, the algorithm should be linear. * For statements, I "trim" the end position of suites to not include the terminal newlines and dedent (this seems to be what people would expect), for example in ```python class C: pass pass ``` the end line and end column for the class definition is (2, 8). * For `end_col_offset` I use the common Python convention for indexing, for example for `pass` the `end_col_offset` is 4 (not 3), so that `[0:4]` gives one the source code that corresponds to the node. * I added a helper function `ast.get_source_segment()`, to get source text segment corresponding to a given AST node. It is also useful for testing. An (inevitable) downside of this PR is that AST now takes almost 25% more memory. I think however it is probably justified by the benefits.
* bpo-35758: Fix building on ARM + MSVC (gh-11531)Minmin Gong2019-01-212-2/+4
| | | | | | | | | | * Disable x87 control word for non-x86 targets On msvc, x87 control word is only available on x86 target. Need to disable it for other targets to prevent compiling problems. * Include immintrin.h on x86 and x64 only Immintrin.h is only available on x86 and x64. Need to disable it for other targets to prevent compiling problems.
* bpo-35423: Stop using the "pending calls" machinery for signals. (gh-10972)Eric Snow2019-01-111-0/+2
| | | | | This change separates the signal handling trigger in the eval loop from the "pending calls" machinery. There is no semantic change and the difference in performance is insignificant. The change makes both components less confusing. It also eliminates the risk of changes to the pending calls affecting signal handling. This is particularly relevant for some upcoming pending calls changes I have in the works.

* bpo-28503: Use crypt_r() when available instead of crypt() (GH-11373)Gregory P. Smith2018-12-301-0/+10
| | | | | Use crypt_r() when available instead of crypt() in the crypt module. As a nice side effect: This also avoids a memory sanitizer flake as clang msan doesn't know about crypt's internal libc allocated buffer.

* bpo-30455: Generate all token related code and docs from Grammar/Tokens. ↵Serhiy Storchaka2018-12-221-8/+3
| | | | | | | | | | | | | | | | | | | (GH-10370) "Include/token.h", "Lib/token.py" (containing now some data moved from "Lib/tokenize.py") and new files "Parser/token.c" (containing the code moved from "Parser/tokenizer.c") and "Doc/library/token-list.inc" (included in "Doc/library/token.rst") are now generated from "Grammar/Tokens" by "Tools/scripts/generate_token.py". The script overwrites files only if needed and can be used on the read-only sources tree. "Lib/symbol.py" is now generated by "Tools/scripts/generate_symbol_py.py" instead of been executable itself. Added new make targets "regen-token" and "regen-symbol" which are now dependencies of "regen-all". The documentation contains now strings for operators and punctuation tokens.
* bpo-35259: Limit `Py_FinalizeEx()` to `Py_LIMITED_API >= 0x03060000`. (GH-10620)Arthur Neufeld2018-12-201-0/+2

| | | | | | | | * Move object.h code surrounded by "#ifndef Py_LIMITED_API" to a new Include/cpython/object.h header file. * "typedef struct _typeobject PyTypeObject;" is now always defined in object.h, but if Py_LIMITED_API is not defined, Include/cpython/object.h also defines the structure. * Complete the printfunc comment to mention Py_LIMITED_API define.
* bpo-33954: Fix _PyUnicode_InsertThousandsGrouping() (GH-10623)Victor Stinner2018-11-261-3/+3
| | | | | | | | | | | | Fix str.format(), float.__format__() and complex.__format__() methods for non-ASCII decimal point when using the "n" formatter. Changes: * Rewrite _PyUnicode_InsertThousandsGrouping(): it now requires a _PyUnicodeWriter object for the buffer and a Python str object for digits. * Rename FILL() macro to unicode_fill(), convert it to static inline function, add "assert(0 <= start);" and rework its code.
* Add assertion to _PyTuple_CAST(op) (GH-10712)Victor Stinner2018-11-261-2/+2
| | | | | | Add "assert(PyTuple_Check(op));" to _PyTuple_CAST() to check that the argument is a tuple object in debug mode. PyTuple_GET_SIZE() now uses _PyTuple_CAST() to get its assertion.

| | | | | | | | | | | | | | | | Include/*.h should be the "portable Python API", whereas Include/cpython/*.h should be the "CPython API": CPython implementation details. Changes: * Create Include/cpython/ subdirectory * "make install" now creates $prefix/include/cpython and copy Include/cpython/* to $prefix/include/cpython * Create Include/cpython/objimpl.h: move objimpl.h code surrounded by "#ifndef Py_LIMITED_API" to cpython/objimpl.h. * objimpl.h now includes cpython/objimpl.h * Windows installer (MSI) now also install Include/ subdirectories: Include/cpython/ and Include/internal/.
* bpo-35059: PyObject_INIT() casts to PyObject* (GH-10674)Victor Stinner2018-11-231-2/+8
| | | | | | PyObject_INIT() and PyObject_INIT_VAR() now cast their first argument to PyObject*, as done in Python 3.7. Revert partially commit b4435e20a92af474f117b78b98ddc6f515363af5.
* bpo-34523: Fix C locale coercion on FreeBSD CURRENT (GH-10672)Victor Stinner2018-11-231-0/+8
| | | | | | | | bpo-34523, bpo-35290: C locale coercion now resets the Python internal "force ASCII" mode. This change fix the filesystem encoding on FreeBSD CURRENT, which has a new "C.UTF-8" locale, when the UTF-8 mode is disabled. Add _Py_ResetForceASCII(): _Py_SetLocaleFromEnv() now calls it.

| | | | | | | | Partially revert commit 5f2df88b63e50d23914e97ec778861a52abdeaad: add "#undef Yield" to .c files after including Python-ast.h. Fix the warning: winbase.h(102): warning C4005: 'Yield': macro redefinition
* bpo-18407: ast.c uses Py_ssize_t for asdl_seq_LEN() iterator (GH-10655)Victor Stinner2018-11-221-1/+1
| | | | | | | When iterating using asdl_seq_LEN(), use 'Py_ssize_t' type instead of 'int' for the iterator variable, to avoid downcast on 64-bit platforms. _Py_asdl_int_seq_new() now also ensures that the index is greater than or equal to 0.
* bpo-35059: Add _PyObject_CAST() macro (GH-10645)Victor Stinner2018-11-225-23/+29
| | | | Add _PyObject_CAST() and _PyVarObject_CAST() macros to cast argument to PyObject* and PyVarObject* properly.
* bpo-35059: Convert _PyObject_GC_TRACK() to inline function (GH-10643)Victor Stinner2018-11-222-36/+61
| | | | | | | | | | | | | * Add _PyObject_ASSERT_FROM() and _PyObject_ASSERT_FAILED_MSG() macros. * PyObject_GC_Track() now calls _PyObject_ASSERT_FAILED_MSG(), instead of Py_FatalError(), if the object is already tracked, to dump more information on error. * _PyObject_GC_TRACK() no longer checks if the object is already tracked at runtime, use an assertion instead for best performances; PyObject_GC_Track() still checks at runtime. * pycore_object.h now includes pycore_pystate.h. * Convert _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() macros to inline functions.
* bpo-35059: Enhance _PyObject_AssertFailed() (GH-10642)Victor Stinner2018-11-211-3/+5

* bpo-28604: Fix localeconv() for different LC_MONETARY (GH-10606)Victor Stinner2018-11-202-5/+7
| | | | | | | | | | | | | | | | | | | | | locale.localeconv() now sets temporarily the LC_CTYPE locale to the LC_MONETARY locale if the two locales are different and monetary strings are non-ASCII. This temporary change affects other threads. Changes: * locale.localeconv() can now set LC_CTYPE to LC_MONETARY to decode monetary fields. * Add LocaleInfo.grouping_buffer: copy localeconv() grouping string since it can be replaced anytime if a different thread calls localeconv(). * _Py_GetLocaleconvNumeric() now requires a "struct lconv *" structure, so locale.localeconv() now longer calls localeconv() twice. Moreover, the function now requires all arguments to be non-NULL. * Rename STATIC_LOCALE_INFO_INIT to LocaleInfo_STATIC_INIT. * Move _Py_GetLocaleconvNumeric() definition from fileutils.h to pycore_fileutils.h. pycore_fileutils.h now includes locale.h. * The _locale module is now built with Py_BUILD_CORE defined.

* bpo-35081: Remove Py_BUILD_CORE from datetime.h (GH-10416)Paul Ganssle2018-11-131-21/+7
| | | | | | | | | | | | | | Datetime macros like PyDate_Check() have two implementations, one using the C API capsule and one using direct access to the datetime type symbols defined in _datetimemodule.c. Since the direct access versions of the macros are only used in _datetimemodule.c, they have been moved out of "datetime.h" and into _datetimemodule.c. The _PY_DATETIME_IMPL macro is currently necessary in order to avoid both duplicate definitions of these macros in _datetimemodule.c and unnecessary declarations of C API capsule-related macros and varibles in datetime.h.

* bpo-35214: Add _Py_ prefix to MEMORY_SANITIZER def. (GH-10503)Gregory P. Smith2018-11-131-2/+2
| | | | Rename our new MEMORY_SANITIZER define to _Py_MEMORY_SANITIZER. Project based C Preprocessor namespacing at its finest. :P
* bpo-35214: Initial clang MemorySanitizer support (GH-10479)Gregory P. Smith2018-11-121-0/+9
| | | | | | | | | | Adds configure flags for msan and ubsan builds to make it easier to enable. These also encode the detail that address sanitizer and memory sanitizer should disable pymalloc. Define MEMORY_SANITIZER when appropriate at build time and adds workarounds to existing code to mark things as initialized where the sanitizer is otherwise unable to determine that. This lets our build succeed under the memory sanitizer. not all tests pass without sanitizer failures yet but we're in pretty good shape after this.
* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-125-2/+2
| | | | | | | | | | | | | | Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h
