Neal Norwitz	adb69fcdff	Merge from ast-arena. This reduces the code in Python/ast.c by ~300 lines, simplifies a lot of error handling code, and fixes many memory leaks.	21 years ago
Neal Norwitz	28b32ac6bc	Simplify logic for handling import *	21 years ago
Neal Norwitz	3715c3e576	Fix a few more ref leaks. Backport candidate	21 years ago
Neal Norwitz	7bcabc60a3	Fix a few more memory leaks Document more info about the benefits of configuring without pymalloc when running valgrind	21 years ago
Neal Norwitz	4737b2348b	Last batch of ref leaks in new AST code. Also converted a bunch of assert(0) to SystemError's. There are still printfs, etc that need to be cleaned up.	21 years ago
Nick Coghlan	944d3eb154	Correctly handle identifiers for anonymous scopes and align genexpr name with symtable.c	21 years ago
Neal Norwitz	b6fc9df8fc	Fix a lot of memory and ref leaks in error paths. (Call symtable_exit_block or compiler_exit_scope as appropriate) Use PyMem_Free on c_future since it was allocated with PyMem_Malloc	21 years ago
Neal Norwitz	2744c6cc35	make internal method static	21 years ago
Neil Schemenauer	c396d9edd6	Ensure that compiler_exit_scope() is called as necessary to free memory allocated by compiler_enter_scope(). Change return type for compiler_exit_scope() to be void.	21 years ago
Neal Norwitz	f1d50684c6	Fix problem handling EXTENDED_ARGs from SF bug # 1333982	21 years ago
Neal Norwitz	7d37f2ff40	cleanup a bit and reuse instrsize (instruction size). working towards fixing problems with EXTENDED_ARG	21 years ago
Neil Schemenauer	dad06a159e	Remove unnecessary local variable.	21 years ago
Neil Schemenauer	8b528b28f1	Fix private name mangling. The symtable also must do mangles so that the scope of names can be correctly determined.	21 years ago
Neil Schemenauer	3a44aaa30f	Use PyTuple_Pack instead of Py_BuildValue.	21 years ago
Neil Schemenauer	d403c45386	Fix arigo's funky LOAD_NAME bug: implicit globals inside classes have historically been looked up using LOAD_NAME, not LOAD_GLOBAL. looked up by LOAD_NAME, not	21 years ago
Neil Schemenauer	ac699efad8	Don't stop generating code for import statements after the first "import as" part. Fixes one bug from #1333982.	21 years ago
Neil Schemenauer	ccd19218bc	Use <lamba> as the function name for lambdas (matches old compiler).	21 years ago
Armin Rigo	3144130217	ANSI-C-ify the placement of local var declarations.	21 years ago
Jeremy Hylton	3e0055f8c6	Merge ast-branch to head This change implements a new bytecode compiler, based on a transformation of the parse tree to an abstract syntax defined in Parser/Python.asdl. The compiler implementation is not complete, but it is in stable enough shape to run the entire test suite excepting two disabled tests.	21 years ago
Tim Peters	ea9dcdc062	com_yield_expr(): Squash new compiler wng about unreferenced local.	21 years ago
Phillip J. Eby	0d6615fd29	PEP 342 implementation. Per Guido's comments, the generator throw() method still needs to support string exceptions, and allow None for the third argument. Documentation updates are needed, too.	21 years ago
Brett Cannon	c9371d4a1b	Fix signedness of various char variables to stop causing a warning under gcc 4.	21 years ago
Brett Cannon	409d8f2ebd	Allow classes to be defined with empty parentheses. This means that ``class C(): pass`` is no longer a syntax error.	22 years ago
Brett Cannon	5dc8ced4a8	Silence a gcc warning about putting in parentheses around && expressions mixed with \|\| expressions. Also clarifies intend of 'if' conditional.	22 years ago
Raymond Hettinger	e63a078635	Preserve sign of -0.0 when result is run through marshal.	22 years ago
Raymond Hettinger	07359a7fed	Document how the pattern recognizer keeps all of its references in bounds. Add a test in case the underlying assumptions ever change (i.e. the compiler starts generating code blocks that are not punctuated by RETURN_VALUE).	22 years ago
Raymond Hettinger	80121491e0	Teach the peepholer to fold unary operations on constants. Afterwards, -0.5 loads in a single step and no longer requires a runtime UNARY_NEGATIVE operation.	22 years ago
Raymond Hettinger	b615bf0681	Remove the set conversion which didn't work with: [] in (0,)	22 years ago
Raymond Hettinger	5e547969f8	Have set conversion replace existing constant if not used elsewhere.	22 years ago
Raymond Hettinger	7fcb7869ba	Adopt Skip's idea to optimize lists of constants in the context of a "in" or "not in" test.	22 years ago
Raymond Hettinger	a164574937	Transform "x in (1,2,3)" to "x in frozenset([1,2,3])". Inspired by Skip's idea to recognize the throw-away nature of sequences in this context and to transform their type to one with better performance.	22 years ago
Raymond Hettinger	9feb267caf	Do not fold a constant if a large sequence will result. Saves space in the presence of code like: (None,)*10000	22 years ago
Armin Rigo	664b43b3f4	Re-running python with/without the -Qnew flag uses incorrectly optimized bytecodes from the previously saved .pyc files. Fixed by disabling the static optimization of BINARY_DIVIDE between two constants.	22 years ago
Raymond Hettinger	c34f8673a1	Teach the peephole optimizer to fold simple constant expressions.	22 years ago
Jeremy Hylton	16b047904c	SF patch 1025636: Check for NULL returns in compile.c:com_import_stmt There is no test for this change, because there is no way to provoke memory errors on demand. Test suite passes, though.	22 years ago
Raymond Hettinger	5dec096e6a	Maintain peepholer's cumlc invariant by updating the running total everytime a LOAD_CONSTANT is encountered, created, or overwritten. Added two tests to cover cases affected by the patch.	22 years ago
Raymond Hettinger	099ecfbec9	Simplify and future proof NOP counting in the peepholer. No longer assumes that the input is NOP free.	22 years ago
Armin Rigo	d7bcf4deb1	Fixed a comment and added another one.	22 years ago
Raymond Hettinger	effb3931ea	Adopt some peepholer suggestions from Armin Rigo: * Use simpler, faster two pass algorithm for markblocks(). * Free the blocks variable if not NULL and exiting without change. * Verify that the rest of the compiler has not set an exception. * Make the test for tuple of constants less restrictive. * Embellish the comment for chained conditional jumps.	22 years ago
Raymond Hettinger	23109ef11e	SF bug #1053819 : Segfault in tuple_of_constants Peepholer could be fooled into misidentifying a tuple_of_constants. Added code to count consecutive occurrences of LOAD_CONST. Use the count to weed out the misidentified cases. Added a unittest.	22 years ago
Raymond Hettinger	9047c8f73d	SF bug #1048870 : call arg of lambda not updating	22 years ago
Raymond Hettinger	fec0c466ad	Improve error message for augmented assignments to genexps or listcomps. Rather than introduce new logic, took the approach of making the message itself more general.	22 years ago
Raymond Hettinger	8ffc1410e2	Fix two erroneous error messages.	22 years ago
Raymond Hettinger	06cc973d06	Replaced a test with an assertion. (Suggested by Michael Hudson.)	22 years ago
Raymond Hettinger	2c31a058eb	SF patch #1031667 : Fold tuples of constants into a single constant Example: >>> import dis >>> dis.dis(compile('1,2,3', '', 'eval')) 0 0 LOAD_CONST 3 ((1, 2, 3)) 3 RETURN_VALUE	22 years ago
Anthony Baxter	1a4ddaecc7	SF patch #1007189 , multi-line imports, for instance: "from blah import (foo, bar baz, bongo)"	22 years ago
Raymond Hettinger	1792bfbf90	Bypass peepholing of code with lineno tables having intervals >= 255. Allows the lineno fixup code to remain simple and not have to deal with multibyte codings. * Add an assertion to that effect. * Remove the XXX comment on the subject.	22 years ago
Raymond Hettinger	65d3c0537a	Fix typo in comment and add clarification.	22 years ago
Raymond Hettinger	ef0a82b682	Simplify chains of conditional jumps. (Suggested by Neal Norwitz.)	22 years ago
Raymond Hettinger	a12fa148d7	Incorporate review comments courtesy of Neal Norwitz: * Perform the code length check earlier. * Eliminate the extra PyMem_Free() upon hitting an EXTENDED_ARG. * Assert that the NOP count used in jump retargeting matches the NOPs eliminated in the final step. * Add an XXX note to indicate that more work is being to done to handle linenotab with intervals > 255.	22 years ago
