* bpo-40939: Remove the old parser (GH-20768)Pablo Galindo2020-06-111-5/+2
| | | This commit removes the old parser, the deprecated parser module, the old parser compatibility flags and environment variables and all associated support code and documentation.
* bpo-40334: Fix error location upon parsing an invalid string literal (GH-19962)Lysandros Nikolaou2020-05-071-4/+3
| | | | | | | When parsing a string with an invalid escape, the old parser used to point to the beginning of the invalid string. This commit changes the new parser to match that behaviour, since it's currently pointing to the end of the string (or to be more precise, to the beginning of the next token).

* bpo-32912: Revert SyntaxWarning on invalid escape sequences. (GH-15195)Gregory P. Smith2019-08-101-4/+33
| | | | | | | | | | | | | | | | | | DeprecationWarning will continue to be emitted for invalid escape sequences in string and bytes literals just as it did in 3.7. SyntaxWarning may be emitted in the future. But per mailing list discussion, we don't yet know when because we haven't settled on how to do so in a non-disruptive manner. (Applies 4c5b6bac2408f879231c7cd38d67657dd4804e7c to the master branch). (This is https://github.com/python/cpython/pull/15142 for master/3.9) https://bugs.python.org/issue32912 Automerge-Triggered-By: @gpshead

| | | | | | | It checks that a SyntaxWarning is raised when compile specified statement, that it is raised only once, that it is converted to a SyntaxError when raised as exception, and that both warning and exception objects have corresponding attributes.
