* bpo-45020: Freeze some of the modules imported during startup. (gh-28335)Eric Snow2021-09-151-9/+14
| | | | | | | Doing this provides significant performance gains for runtime startup (~15% with all the imported modules frozen). We don't yet freeze all the imported modules because there are a few hiccups in the build systems we need to sort out first. (See bpo-45186 and bpo-45188.) Note that in PR GH-28320 we added a command-line flag (-X frozen_modules=[on|off]) that allows users to opt out of (or into) using frozen modules. The default is still "off" but we will change it to "on" as soon as we can do it in a way that does not cause contributors pain. https://bugs.python.org/issue45020

* bpo-35321: Set the spec origin to frozen in frozen modules (#11732)Nina Zakharenko2019-02-051-0/+11
| | | | | | | | | | * bpo-35321: Set the spec origin to frozen in frozen modules This fix correctly sets the spec origin to "frozen" for the _frozen_importlib module. Note that the origin was already correctly set in _frozen_importlib_external. * 📜🤖 Added by blurb_it.
* closes bpo-34056: Always return bytes from _HackedGetData.get_data(). (GH-8130)Benjamin Peterson2018-07-071-0/+15
| | | | | | | | | | * Always return bytes from _HackedGetData.get_data(). Ensure the imp.load_source shim always returns bytes by reopening the file in binary mode if needed. Hash-based pycs have to receive the source code in bytes. It's tempting to change imp.get_suffixes() to always return 'rb' as a mode, but that breaks some stdlib tests and likely 3rdparty code, too.
* closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)Benjamin Peterson2017-12-091-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | Python now supports checking bytecode cache up-to-dateness with a hash of the source contents rather than volatile source metadata. See the PEP for details. While a fairly straightforward idea, quite a lot of code had to be modified due to the pervasiveness of pyc implementation details in the codebase. Changes in this commit include: - The core changes to importlib to understand how to read, validate, and regenerate hash-based pycs. - Support for generating hash-based pycs in py_compile and compileall. - Modifications to our siphash implementation to support passing a custom key. We then expose it to importlib through _imp. - Updates to all places in the interpreter, standard library, and tests that manually generate or parse pyc files to grok the new format. - Support in the interpreter command line code for long options like --check-hash-based-pycs. - Tests and documentation for all of the above.

* bpo-31676: Fix test_imp.test_load_source() side effect (#3871)Victor Stinner2017-10-131-2/+7

| | | | | | | Based on patch by Victor Stinner. Add private C API function _PyUnicode_AsUnicode() which is similar to PyUnicode_AsUnicode(), but checks for null characters.

| | | | | | | | To resolve a compatibility problem found with py2exe and pywin32, imp.load_dynamic() once again ignores previously loaded modules to support Python modules replacing themselves with extension modules. Patch by Petr Viktorin.
