[3.8] bpo-37830: Fix compilation of break and continue in finally. (GH-15320) (GH-15456)

2019-08-24T10:41:53+00:00

"finally" block when the corresponding "try" block
contains "return" with a non-constant value.

bpo-37213: Handle negative line deltas correctly in the peephole optimizer (GH-13969)

2019-06-13T18:35:40+00:00

The peephole optimizer was not optimizing correctly bytecode after negative deltas were introduced. This is due to the fact that some special values (255) were being searched for in both instruction pointer delta and line number deltas.

bpo-16806: Fix `lineno` and `col_offset` for multi-line string tokens (GH-10021)

2019-01-13T04:05:13+00:00

bpo-31241: Fix AST node position for list and generator comprehensions. (GH-10633)

2018-11-27T07:40:29+00:00

The lineno and col_offset attributes of AST nodes for list comprehensions,
generator expressions and tuples are now point to the opening parenthesis or
square brace. For tuples without parenthesis they point to the position
of the first item.

bpo-34100: Merge constants recursively (GH-8341)

2018-11-26T12:23:22+00:00

There are some same consts in a module.  This commit merges them into
single instance.  It reduces number of objects in memory after loading modules.

bpo-34726: Fix handling of hash-based pycs in zipimport. (GH-10327)

2018-11-07T18:34:59+00:00

Current support for hash-based bytecode files in `zipimport` is rather
sparse, which leads to test failures when the test suite is ran with
the ``SOURCE_DATE_EPOCH`` environment variable set.

This teaches zipimport to handle hash-based pycs properly.
