* bpo-35321: Set the spec origin to frozen in frozen modules (#11732)Nina Zakharenko2019-02-051-2/+4
| | | | | | | | | | * 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.
* bpo-35133: Fix mistakes when concatenate string literals on different lines. ↵Serhiy Storchaka2018-11-051-1/+1
| | | | | | | | | | (GH-10284) Two kind of mistakes: 1. Missed space. After concatenating there is no space between words. 2. Missed comma. Causes unintentional concatenating in a list of strings.
* bpo-33331: Clean modules in the reversed order in PyImport_Cleanup(). (GH-6565)Serhiy Storchaka2018-10-291-56/+62
| | | | | | Modules imported last are now cleared first at interpreter shutdown. A newly imported module is moved to the end of sys.modules, behind modules on which it depends.
* bpo-35024: Remove redundant and possibly incorrect verbose message after ↵Quentin Agren2018-10-261-1/+0
| | | | | | | | | writing '.pyc' (GH-9998) Since `SourceFileLoader.set_data()` catches exceptions raised by `_write_atomic()` and logs an informative message consequently, always logging successful outcome in 'SourceLoader.get_code()' seems redundant. https://bugs.python.org/issue35024

* bpo-33499: Add PYTHONPYCACHEPREFIX env var for alt bytecode cache location. ↵Carl Meyer2018-06-161-10/+52
| | | | | | | | | | | | | | | (GH-6834) In some development setups it is inconvenient or impossible to write bytecode caches to the code tree, but the bytecode caches are still useful. The PYTHONPYCACHEPREFIX environment variable allows specifying an alternate location for cached bytecode files, within which a directory tree mirroring the code tree will be created. This cache tree is then used (for both reading and writing) instead of the local `__pycache__` subdirectory within each source directory. Exposed at runtime as sys.pycache_prefix (defaulting to None), and can be set from the CLI as "-X pycache_prefix=path". Patch by Carl Meyer.

| | | | | invalidating caches (GH-6402) An entry of None in sys.path_importer_cache represents a negative/missing finder for a path, so clearing it out makes sense.

* closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)Benjamin Peterson2017-12-092-55/+149
| | | | | | | | | | | | | | | | | | | | | | | | | 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-21720: Restore the Python 2.7 logic in handling a fromlist. (#4118)Serhiy Storchaka2017-10-261-7/+13

| | | | | | | | | Use sys.modules.get() in the "with _ModuleLockManager(name):" block to protect the dictionary key with the module lock and use an atomic get to prevent race condition. Remove also _bootstrap._POPULATE since it was unused (_bootstrap_external now has its own _POPULATE object), add a new _SENTINEL object instead.

* bpo-30891: Fix importlib _find_and_load() race condition (#2646)Victor Stinner2017-07-101-28/+30
| | | | | | * Rewrite importlib _get_module_lock(): it is now responsible to hold the imp lock directly. * _find_and_load() now holds the module lock to check if name is in sys.modules to prevent a race condition
