/* Frozen modules initializer
|
|
*
|
|
* Frozen modules are written to header files by Programs/_freeze_module.
|
|
* These files are typically put in Python/frozen_modules/. Each holds
|
|
* an array of bytes named "_Py_M__<module>", which is used below.
|
|
*
|
|
* These files must be regenerated any time the corresponding .pyc
|
|
* file would change (including with changes to the compiler, bytecode
|
|
* format, marshal format). This can be done with "make regen-frozen".
|
|
* That make target just runs Tools/scripts/freeze_modules.py.
|
|
*
|
|
* The freeze_modules.py script also determines which modules get
|
|
* frozen. Update the list at the top of the script to add, remove,
|
|
* or modify the target modules. Then run the script
|
|
* (or run "make regen-frozen").
|
|
*
|
|
* The script does the following:
|
|
*
|
|
* 1. run Programs/_freeze_module on the target modules
|
|
* 2. update the includes and _PyImport_FrozenModules[] in this file
|
|
* 3. update the FROZEN_FILES variable in Makefile.pre.in
|
|
* 4. update the per-module targets in Makefile.pre.in
|
|
* 5. update the lists of modules in PCbuild/_freeze_module.vcxproj and
|
|
* PCbuild/_freeze_module.vcxproj.filters
|
|
*
|
|
* (Note that most of the data in this file is auto-generated by the script.)
|
|
*
|
|
* Those steps can also be done manually, though this is not recommended.
|
|
* Expect such manual changes to be removed the next time
|
|
* freeze_modules.py runs.
|
|
* */
