cpython-lru_cache-weakref: Lib/test/test

annotate Lib/test/test_syntax.py @ 87690:66c1c9f32567 default tip

Add use_weakref option to functools.lru_cache The use_weakref option makes lru_cache create weak references to the function arguments when creating the cache key, which prevents them from staying in the memory forever even after all other references to them are gone. This is a proof of concept for http://bugs.python.org/issue19859

a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	11 each C call that raises SyntaxError. There are several modules that
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	12 raise these exceptions-- ast.c, compile.c, future.c, pythonrun.c, and

a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	16 errors are tested here at the moment. We should add some tests; since
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	17 there are infinitely many programs with invalid syntax, we would need
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	18 to be judicious in selecting some.

a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	20 The compiler generates a synthetic module name for code executed by
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	21 doctest. Since all the code comes from the same module, a suffix like
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	22 [1] is appended to the module name, As a consequence, changing the
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	23 order of tests in this module means renumbering all the errors after
