* [Tools/peg_generator/pegen/parser.py] Fix typo: s/wether/whether/ (GH-28739)Ikko Ashimine2021-10-051-1/+1

* bpo-45020: Identify which frozen modules are actually aliases. (gh-28655)Eric Snow2021-10-051-1/+38
| | | | | | | In the list of generated frozen modules at the top of Tools/scripts/freeze_modules.py, you will find that some of the modules have a different name than the module (or .py file) that is actually frozen. Let's call each case an "alias". Aliases do not come into play until we get to the (generated) list of modules in Python/frozen.c. (The tool for freezing modules, Programs/_freeze_module, is only concerned with the source file, not the module it will be used for.) Knowledge of which frozen modules are aliases (and the identity of the original module) normally isn't important. However, this information is valuable when we go to set __file__ on frozen stdlib modules. This change updates Tools/scripts/freeze_modules.py to map aliases to the original module name (or None if not a stdlib module) in Python/frozen.c. We also add a helper function in Python/import.c to look up a frozen module's alias and add the result of that function to the frozen info returned from find_frozen(). https://bugs.python.org/issue45020
* bpo-43760: Check for tracing using 'bitwise or' instead of branch in ↵Mark Shannon2021-10-051-1/+1

* bpo-45020: Add more test cases for frozen modules. (gh-28664)Eric Snow2021-10-012-6/+12
| | | | | I've added a number of test-only modules. Some of those cases are covered by the recently frozen stdlib modules (and some will be once we add encodings back in). However, I figured we'd play it safe by having a set of modules guaranteed to be there during tests. https://bugs.python.org/issue45020
* Fix EncodingWarning in freeze_modules. (GH-28591)Inada Naoki2021-09-301-4/+4

* bpo-45020: Do not freeze <pkg>/__init__.py twice. (gh-28635)Eric Snow2021-09-291-0/+7
| | | | | Currently we're freezing the __init__.py twice, duplicating the built data unnecessarily With this change we do it once. There is no change in runtime behavior. https://bugs.python.org/issue45020
* Select correct tool platform when building on Windows ARM64 natively (GH-28491)Niyas Sait2021-09-271-1/+5

* bpo-45020: Fix some corner cases for frozen module generation. (gh-28538)Eric Snow2021-09-242-32/+76
| | | | | This also includes some cleanup in preparation for a PR to make the "make all" output less noisy. https://bugs.python.org/issue45020
* [codemod] Fix non-matching bracket pairs (GH-28473)Mohamad Mansour2021-09-211-1/+1

* bpo-45020: Freeze os, site, and codecs. (gh-28398)Eric Snow2021-09-171-11/+11
| | | https://bugs.python.org/issue45020
* bpo-45020: Fix build out of source tree (GH-28410)Victor Stinner2021-09-171-4/+10
| | | | | | * Makefile.pre.in: Add $(srcdir) when needed, remove it when it was used by mistake. * freeze_modules.py tool uses ./Programs/_freeze_module if the executable doesn't exist in the source tree.
* bpo-45231: update_file.py preserves end of line (GH-28411)Victor Stinner2021-09-171-1/+13
| | | | | | The update_file.py tool now preserves the end of line of the updated file. Fix the "make regen-frozen" command: it no longer changes the end of line of PCbuild/ files on Unix. Git changes the end of line depending on the platform.
* bpo-45020: Drop the frozen .h files from the repo. (gh-28392)Eric Snow2021-09-161-7/+4
| | | | | The main advantage is that the files will no longer show up in diffs and PRs. That means, for a PR, the number of files / lines changed will more clearly reflect the actual change. (This is essentially an un-revert of gh-28375.) https://bugs.python.org/issue45020
* bpo-45020: Revert "Drop the frozen .h files from the repo." (gh-28380)Eric Snow2021-09-161-3/+6
| | | | | gh-28375 broke one of the buildbots. Until I figure out why, I'm rolling the change back. https://bugs.python.org/issue45020
* bpo-45020: Drop the frozen .h files from the repo. (gh-28375)Eric Snow2021-09-161-6/+3
| | | | | The main advantage is that the files will no longer show up in diffs and PRs. That means, for a PR, the number of files / lines changed will more clearly reflect the actual change. https://bugs.python.org/issue45020
* bpo-45019: Clean up the frozen __hello__ module. (gh-28374)Eric Snow2021-09-151-4/+4
| | | | | Here's one more small cleanup that should have been in PR gh-28319. We eliminate stdout side-effects from importing the frozen __hello__ module, and update tests accordingly. We also move the module's source file into Lib/ from Toos/freeze/flag.py. https://bugs.python.org/issue45019
* bpo-45188: Windows now regenerates frozen modules at the start of build ↵Steve Dower2021-09-151-13/+47
| | | | | | | instead of late (GH-28322) This will enable us to drop the frozen module header files from the repository. It does currently cause many source files to be built twice, which just takes more time. For whoever comes to fix this in the future, the files shared between freeze_module and pythoncore should be put into a static library that is consumed by both.
* bpo-45020: Freeze some of the modules imported during startup. (gh-28335)Eric Snow2021-09-151-3/+28
| | | | | | | 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-45019: Do some cleanup related to frozen modules. (gh-28319)Eric Snow2021-09-132-103/+225
| | | | | There are a few things I missed in gh-27980. This is a follow-up that will make subsequent PRs cleaner. It includes fixes to tests and tools that reference the frozen modules. https://bugs.python.org/issue45019
* bpo-43413: Fix handling keyword arguments in subclasses of some buitin ↵Serhiy Storchaka2021-09-121-2/+8
| | | | | | | | classes (GH-26456) * Constructors of subclasses of some buitin classes (e.g. tuple, list, frozenset) no longer accept arbitrary keyword arguments. * Subclass of set can now define a __new__() method with additional keyword parameters without overriding also __init__().

* bpo-45019: Add a tool to generate list of modules to include for frozen ↵Eric Snow2021-08-302-6/+526
| | | | | | | modules (gh-27980) Frozen modules must be added to several files in order to work properly. Before this change this had to be done manually. Here we add a tool to generate the relevant lines in those files instead. This helps us avoid mistakes and omissions. https://bugs.python.org/issue45019
