* bpo-32836: Remove obsolete code from symtable pass (GH-5680)Nitish Chandra2018-02-261-25/+0
| | | | | | | When comprehensions switched to using a nested scope, the old code for generating a temporary name to hold the accumulation target became redundant, but was never actually removed. Patch by Nitish Chandra.
* bpo-10544: Disallow "yield" in comprehensions and generator expressions. ↵Serhiy Storchaka2018-02-041-24/+7
| | | | (GH-4564)
* bpo-10544: Deprecate "yield" in comprehensions and generator expressions. ↵Serhiy Storchaka2017-12-011-1/+30
| | | | | | | | | | | | | | (GH-4579) The current behaviour of yield expressions inside comprehensions and generator expressions is essentially an accident of implementation - it arises implicitly from the way the compiler handles yield expressions inside nested functions and generators. Since the current behaviour wasn't deliberately designed, and is inherently confusing, we're deprecating it, with no current plans to reintroduce it. Instead, our advice will be to use a named nested generator definition for cases where this behaviour is desired.
* bpo-28936: Detect lexically first syntax error first (#4097)Ivan Levkivskyi2017-10-261-18/+16
| | | | Lexically first global and nonlocal syntax errors at given scope should be detected first.
* bpo-30860: Consolidate stateful runtime globals. (#3397)Eric Snow2017-09-081-0/+4
| | | | | | | * group the (stateful) runtime globals into various topical structs * consolidate the topical structs under a single top-level _PyRuntimeState struct * add a check-c-globals.py script that helps identify runtime globals Other globals are excluded (see globals.txt and check-c-globals.py).

* | Fix potential NULL pointer dereference in update_symbols()Christian Heimes2016-09-081-1/+1
| | | | | | | | | | | | symtable_analyze() calls analyze_block() with bound=NULL. Theoretically that NULL can be passed down to update_symbols(). update_symbols() may deference NULL and pass it to PySet_Contains()

It can be used by external AST optimizers, but the compiler does not emit directly such node. An optimizer can replace the following AST nodes with ast.Constant: * ast.NameConstant: None, False, True * ast.Num: int, float, complex * ast.Str: str * ast.Bytes: bytes * ast.Tuple if items are constants too: tuple * frozenset Update code to accept ast.Constant instead of ast.Num and/or ast.Str: * compiler * docstrings * ast.literal_eval() * Tools/parser/unparse.py
