cpython-lru_cache-weakref: Modules/parsermodule.c annotate

annotate Modules/parsermodule.c @ 49783:eade47dfc1e4 legacy-trunk

Fixed issue #4233. Changed semantic of _fileio.FileIO's close() method on file objects with closefd=False. The file descriptor is still kept open but the file object behaves like a closed file. The FileIO object also got a new readonly attribute closefd. Approved by Barry Backport of r67106 from the py3k branch

4084 7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	11 * This module serves to replace the original parser module written
7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	12 * by Guido. The functionality is not matched precisely, but the
7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	13 * original may be implemented on top of this. This is desirable
7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	14 * since the source of the text to be parsed is now divorced from

4084 7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	17 * Unlike the prior interface, the ability to give a parse tree
7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	18 * produced by Python code as a tuple to the compiler is enabled by
