| | | | | | | | | | | | | | | | | | | Issue #27213: Rework CALL_FUNCTION* opcodes to produce shorter and more efficient bytecode: * CALL_FUNCTION now only accepts position arguments * CALL_FUNCTION_KW accepts position arguments and keyword arguments, but keys of keyword arguments are packed into a constant tuple. * CALL_FUNCTION_EX is the most generic, it expects a tuple and a dict for positional and keyword arguments. CALL_FUNCTION_VAR and CALL_FUNCTION_VAR_KW opcodes have been removed. 2 tests of test_traceback are currently broken: skip test, the issue #28050 was created to track the issue. Patch by Demur Rumed, design by Serhiy Storchaka, reviewed by Serhiy Storchaka and Victor Stinner.

* Issue #24400: Introduce a distinct type for 'async def' coroutines.Yury Selivanov2015-06-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary of changes: 1. Coroutines now have a distinct, separate from generators type at the C level: PyGen_Type, and a new typedef PyCoroObject. PyCoroObject shares the initial segment of struct layout with PyGenObject, making it possible to reuse existing generators machinery. The new type is exposed as 'types.CoroutineType'. As a consequence of having a new type, CO_GENERATOR flag is no longer applied to coroutines. 2. Having a separate type for coroutines made it possible to add an __await__ method to the type. Although it is not used by the interpreter (see details on that below), it makes coroutines naturally (without using __instancecheck__) conform to collections.abc.Coroutine and collections.abc.Awaitable ABCs. [The __instancecheck__ is still used for generator-based coroutines, as we don't want to add __await__ for generators.] 3. Add new opcode: GET_YIELD_FROM_ITER. The opcode is needed to allow passing native coroutines to the YIELD_FROM opcode. Before this change, 'yield from o' expression was compiled to: (o) GET_ITER LOAD_CONST YIELD_FROM Now, we use GET_YIELD_FROM_ITER instead of GET_ITER. The reason for adding a new opcode is that GET_ITER is used in some contexts (such as 'for .. in' loops) where passing a coroutine object is invalid. 4. Add two new introspection functions to the inspec module: getcoroutinestate(c) and getcoroutinelocals(c). 5. inspect.iscoroutine(o) is updated to test if 'o' is a native coroutine object. Before this commit it used abc.Coroutine, and it was requested to update inspect.isgenerator(o) to use abc.Generator; it was decided, however, that inspect functions should really be tailored for checking for native types. 6. sys.set_coroutine_wrapper(w) API is updated to work with only native coroutines. Since types.coroutine decorator supports any type of callables now, it would be confusing that it does not work for all types of coroutines. 7. Exceptions logic in generators C implementation was updated to raise clearer messages for coroutines: Before: TypeError("generator raised StopIteration") After: TypeError("coroutine raised StopIteration")

This limitation of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF). This sample was valid in 2.6, but fails to compile in 3.x without this change:: >>> def f(): ... def print_error(): ... print(e) ... try: ... something ... except Exception as e: ... print_error() ... # implicit "del e" here This sample has always been invalid in Python, and now works:: >>> def outer(x): ... def inner(): ... return x ... inner() ... del x There is no need to bump the PYC magic number: the new opcode is used for code that did not compile before.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch by Antoine Pitrou optimizes the bytecode for conditional branches by merging the following "POP_TOP" instruction into the conditional jump. For example, the list comprehension "[x for x in l if not x]" produced the following bytecode: 1 0 BUILD_LIST 0 3 LOAD_FAST 0 (.0) >> 6 FOR_ITER 23 (to 32) 9 STORE_FAST 1 (x) 12 LOAD_FAST 1 (x) 15 JUMP_IF_TRUE 10 (to 28) 18 POP_TOP 19 LOAD_FAST 1 (x) 22 LIST_APPEND 2 25 JUMP_ABSOLUTE 6 >> 28 POP_TOP 29 JUMP_ABSOLUTE 6 >> 32 RETURN_VALUE but after the patch it produces the following bytecode: 1 0 BUILD_LIST 0 3 LOAD_FAST 0 (.0) >> 6 FOR_ITER 18 (to 27) 9 STORE_FAST 1 (x) 12 LOAD_FAST 1 (x) 15 POP_JUMP_IF_TRUE 6 18 LOAD_FAST 1 (x) 21 LIST_APPEND 2 24 JUMP_ABSOLUTE 6 >> 27 RETURN_VALUE Notice that not only the code is shorter, but the conditional jump (POP_JUMP_IF_TRUE) jumps right to the start of the loop instead of going through the JUMP_ABSOLUTE at the end. "continue" statements are helped similarly. Furthermore, the old jump opcodes (JUMP_IF_FALSE, JUMP_IF_TRUE) have been replaced by two new opcodes: - JUMP_IF_TRUE_OR_POP, which jumps if true and pops otherwise - JUMP_IF_FALSE_OR_POP, which jumps if false and pops otherwise

* Merging the py3k-pep3137 branch back into the py3k branch.Guido van Rossum2007-11-061-1/+1
| | | | | | | | | | | | | | No detailed change log; just check out the change log for the py3k-pep3137 branch. The most obvious changes: - str8 renamed to bytes (PyString at the C level); - bytes renamed to buffer (PyBytes at the C level); - PyString and PyUnicode are no longer compatible. I.e. we now have an immutable bytes type and a mutable bytes type. The behavior of PyString was modified quite a bit, to make it more bytes-like. Some changes are still on the to-do list.

The Maildir specification doesn't seem to say anything about this situation, and it can happen if you're keeping a Maildir mailbox in Subversion (.svn directories) or some similar system. The patch just ignores directories in the cur/, new/, tmp/ folders. ........ r56392 | facundo.batista | 2007-07-14 15:41:45 -0700 (Sat, 14 Jul 2007) | 6 lines First version.

* Hide list comp variables and support set comprehensionsNick Coghlan2007-04-151-0/+1
|
* Implement PEP 3115 -- new metaclass syntax and semantics.Guido van Rossum2007-03-181-5/+5
| | | | | | | The compiler package hasn't been updated yet; test_compiler.py fails. Otherwise all tests seem to be passing now. There are no occurrences of __metaclass__ left in the standard library. Docs have not been updated.
* Bytes literal.Thomas Wouters2007-02-231-1/+1
|
* * Remove PRINT_ITEM(_TO), PRINT_NEWLINE(_TO) opcodes.Georg Brandl2007-02-091-4/+1
| | | | | | | * Fix some docstrings and one Print -> print. * Fix test_{class,code,descrtut,dis,extcall,parser,popen,pkg,subprocess,syntax,traceback}. These were the ones that generated code with a print statement. In most remaining failing tests there's an issue with the soft space.
* Patch #1550800: make exec a function.Georg Brandl2006-09-061-1/+1
|
* SF patch 1547796 by Georg Brandl -- set literals.Guido van Rossum2006-08-281-5/+6
|
* Remove the UNARY_CONVERT opcode (was used for backticks). Also bumped up theBrett Cannon2006-08-251-1/+0
| | | | import MAGIC number.
* INPLACE_DIVIDE is no longer necessary (INPLACE_TRUE_DIVIDE is used).Neal Norwitz2006-03-171-1/+1
|
* Get rid of last vestiges of BINARY_DIVIDE.Neal Norwitz2006-03-161-1/+1
|
* PEP 343 -- the with-statement.Guido van Rossum2006-02-271-2/+1
| | | | | | | | | | | | | This was started by Mike Bland and completed by Guido (with help from Neal). This still needs a __future__ statement added; Thomas is working on Michael's patch for that aspect. There's a small amount of code cleanup and refactoring in ast.c, compile.c and ceval.c (I fixed the lltrace behavior when EXT_POP is used -- however I had to make lltrace a static global).
* Install two code generation optimizations that depend on NOP.Raymond Hettinger2004-06-211-0/+1
| | | | Reduces the cost of "not" to almost zero.
* SF patch #910929: Optimize list comprehensionsRaymond Hettinger2004-03-071-0/+1
| | | | | Add a new opcode, LIST_APPEND, and apply it to the code generation for list comprehensions. Reduces the per-loop overhead by about a third.
* Revert the previous enhancement to the bytecode optimizer.Raymond Hettinger2003-04-241-2/+0
| | | | The additional code complexity and new NOP opcode were not worth it.
* Improved the bytecode optimizer.Raymond Hettinger2003-04-221-0/+2
| | | | | | | | | | | | | | * Can now test for basic blocks. * Optimize inverted comparisions. * Optimize unary_not followed by a conditional jump. * Added a new opcode, NOP, to keep code size constant. * Applied NOP to previous transformations where appropriate. Note, the NOP would not be necessary if other functions were added to re-target jump addresses and update the co_lnotab mapping. That would yield slightly faster and cleaner bytecode at the expense of optimizer simplicity and of keeping it decoupled from the line-numbering structure.
