* [3.7] bpo-39769: Fix compileall ddir for subpkgs. (GH-18676) (GH-18718) ↵Gregory P. Smith2020-03-011-0/+11
| | | | | | | | | | | | | | | | | | | | | | (GH-18725) Fix compileall.compile_dir() ddir= behavior on sub-packages. Fixes compileall.compile_dir's ddir parameter and compileall command line flag `-d` to no longer write the wrong pathname to the generated pyc file for submodules beneath the root of the directory tree being compiled. This fixes a regression introduced with Python 3.5. Tests backported from GH 02673352b5db6ca4d3dc804965facbedfe66425d, the implementation is different due to intervening code changes. But still quiet simple. Why was the bug ever introduced? The refactoring to add parallel execution kept the ddir -> dfile computations but discarded the results instead of sending them to compile_file(). This fixes that. Lack of tests meant this went unnoticed.. (cherry picked from commit ce720d3e0674d6ac6f1b950c20a89be4cfde7853) Co-authored-by: Gregory P. Smith <greg@krypto.org> [Google]

* bpo-34022: Stop forcing of hash-based invalidation with SOURCE_DATE_EPOCH ↵Miss Islington (bot)2018-11-281-0/+15
| | | | | | | | | | | | | | | | | | | | | | | (GH-9607) Unconditional forcing of ``CHECKED_HASH`` invalidation was introduced in 3.7.0 in bpo-29708. The change is bad, as it unconditionally overrides *invalidation_mode*, even if it was passed as an explicit argument to ``py_compile.compile()`` or ``compileall``. An environment variable should *never* override an explicit argument to a library function. That change leads to multiple test failures if the ``SOURCE_DATE_EPOCH`` environment variable is set. This changes ``py_compile.compile()`` to only look at ``SOURCE_DATE_EPOCH`` if no explicit *invalidation_mode* was specified. I also made various relevant tests run with explicit control over the value of ``SOURCE_DATE_EPOCH``. While looking at this, I noticed that ``zipimport`` does not work with hash-based .pycs _at all_, though I left the fixes for subsequent commits.

* closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)Benjamin Peterson2017-12-092-15/+197
| | | | | | | | | | | | | | | | | | | | | | | | | 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-29514: Check magic number for micro release Add a dict importlib.util.EXPECTED_MAGIC_NUMBERS which details the initial and expected pyc magic number for each minor release. This gives a mechanism for users to check if the magic number has changed within a release and for a test to ensure procedure is followed if a change is necessary. Add a test to check the current MAGIC_NUMBER against the expected number for the release if the current release is at candidate or final level. On test failure, describe to the developer the procedure for changing the magic number. * Simplify magic number release test Simplify the magic number release test by removing EXPECTED_MAGIC_NUMBERS table and making the expected magic number self-contained within the test. BPO: 29514 * Improve magic number test execution and message Improve the execution of the magic number test by using skipUnless for alpha and beta releases, and directly inheriting from unittest.TestCase rather than using the machinery for the other tests. Also improve the error message to explain the reason for caution in changing the magic number. BPO: 29514
