* bpo-39156: Break up COMPARE_OP into four logically distinct opcodes. (GH-17754)Mark Shannon2020-01-141-71/+70
| | | | | | | | Break up COMPARE_OP into four logically distinct opcodes: * COMPARE_OP for rich comparisons * IS_OP for 'is' and 'is not' tests * CONTAINS_OP for 'in' and 'is not' tests * JUMP_IF_NOT_EXC_MATCH for checking exceptions in 'try-except' statements.

* bpo-33041: Rework compiling an "async for" loop. (#6142)Serhiy Storchaka2018-03-231-2/+1
| | | | | | | | * Added new opcode END_ASYNC_FOR. * Setting global StopAsyncIteration no longer breaks "async for" loops. * Jumping into an "async for" loop is now disabled. * Jumping out of an "async for" loop no longer corrupts the stack. * Simplify the compiler.

* bpo-31183: `dis` now handles coroutines & async generators (GH-3077)syncosmic2017-08-181-5/+27
| | | | | | | | | | | | | | Coroutines and async generators use a distinct attribute name for their code objects, so this updates the `dis` module to correctly disassemble objects with those attributes. Due to the increase in the test module length, it also fixes some latent defects in the tests related to how the displayed source line numbers are extracted. https://bugs.python.org/issue31230 is a follow-up issue suggesting we may want to solve this a different way, by instead giving all these object types a common `__code__` attribute, avoiding the need for special casing in the `dis` module.

* Rework CALL_FUNCTION* opcodesVictor Stinner2016-09-091-18/+18
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - confusing line_offset parameter -> first_line parameter - systematically test and fix new file parameter - remove redundant Bytecode.show_info() API - rename Bytecode.display_code() to Bytecode.dis() and have it return the multi-line string rather than printing it directly - eliminated some not-so-helpful helpers from the bytecode_helper test support module Also fixed a longstanding defect (worked around in the test suite) where lines emitted by the dis module could include trailing white space. That no longer happens, allowing the formatting tests to be simplified to use plain string comparisons.
