Pablo Galindo	c878a97968	bpo-44180: Fix edge cases in invalid assigment rules in the parser (GH-26283) The invalid assignment rules are very delicate since the parser can easily raise an invalid assignment when a keyword argument is provided. As they are very deep into the grammar tree, is very difficult to specify in which contexts these rules can be used and in which don't. For that, we need to use a different version of the rule that doesn't do error checking in those situations where we don't want the rule to raise (keyword arguments and generator expressions). We also need to check if we are in left-recursive rule, as those can try to eagerly advance the parser even if the parse will fail at the end of the expression. Failing to do this allows the parser to start parsing a call as a tuple and incorrectly identify a keyword argument as an invalid assignment, before it realizes that it was not a tuple after all.	5 years ago

Pablo Galindo	a77aac4fca	bpo-43914: Highlight invalid ranges in SyntaxErrors (#25525 ) To improve the user experience understanding what part of the error messages associated with SyntaxErrors is wrong, we can highlight the whole error range and not only place the caret at the first character. In this way: >>> foo(x, z for z in range(10), t, w) File "<stdin>", line 1 foo(x, z for z in range(10), t, w) ^ SyntaxError: Generator expression must be parenthesized becomes >>> foo(x, z for z in range(10), t, w) File "<stdin>", line 1 foo(x, z for z in range(10), t, w) ^^^^^^^^^^^^^^^^^^^^ SyntaxError: Generator expression must be parenthesized	5 years ago

Pablo Galindo	58fb156edd	bpo-42997: Improve error message for missing : before suites (GH-24292) * Add to the peg generator a new directive ('&&') that allows to expect a token and hard fail the parsing if the token is not found. This allows to quickly emmit syntax errors for missing tokens. * Use the new grammar element to hard-fail if the ':' is missing before suites.	5 years ago

Lysandros Nikolaou	02cdfc93f8	bpo-42218: Correctly handle errors in left-recursive rules (GH-23065) Left-recursive rules need to check for errors explicitly, since even if the rule returns NULL, the parsing might continue and lead to long-distance failures.

Lysandros Nikolaou	bca7014032	bpo-42123: Run the parser two times and only enable invalid rules on the second run (GH-22111) * Implement running the parser a second time for the errors messages The first parser run is only responsible for detecting whether there is a `SyntaxError` or not. If there isn't the AST gets returned. Otherwise, the parser is run a second time with all the `invalid_*` rules enabled so that all the customized error messages get produced.	5 years ago
