This module provides a way to build librt extension modules once and cache them across test runs, and across different test cases in a single run. The cache is invalidated when source files or details of the build environment change. Note: Tests must run in a subprocess to use the cached librt, since importing this module also triggers the import of the regular installed librt. Usage: from mypyc.test.librt_cache import get_librt_path, run_with_librt # Get path to built librt (builds if needed) path = get_librt_path() # Run a test file in subprocess with built librt result = run_with_librt("test_librt.py") ) annotationsN)Any) LIBRT_MODULES get_cflags include_dir)RUNTIME_C_FILES)PREFIXcPddlm}tj}|j |rdnd|j d|j |j t jj tt d}|j |rdndttjd }|j |rd nd |j}|j |jj d D]F}tjj!|d }|j |d|j Ht"D]} tj$j't)| } |j | j dzt+| d5} |j | j-dddt.D]\} } }}| |zD]}tj$j't)|} |j |j dzt+| d5} |j | j-ddd|j1ddS#1swY8xYw#1swYxYw)zFCompute hash for librt build, including sources and build environment.r) ccompilersexpsnoexpzopt=gettotalrefcountsdebugsreleasePy_GIL_DISABLEDs freethreadedsgil)CCCXXCFLAGSCPPFLAGSLDFLAGS=|rbN) distutilsr hashlibsha256updateencodesysversionhasattrbool sysconfigget_config_var new_compiler compiler_typeosenvirongetrpathjoinropenreadr hexdigest) experimental opt_levelr his_debugis_free_threadedcompilervarvalnamer(fmodfilesextraincludesfnames [/home/oem/CyberBrain26-unified/.venv/lib/python3.12/site-packages/mypyc/test/librt_cache.py_librt_build_hashr=%s%$AHH|V2HHtI;  & & ()HHS[[   !"s./HHHXz2I445FGHHH 0_f=**,HHHX # # * * ,-=*jjnnS"% C5#&&()* ww||KM40 %& $   HHQVVX    (5##UE8U] #E77<< u5D HHU\\^d* +dD! #Q" # # ## ;;="    # #s: J JJ J% c $t}t||}ttDcgc]0}|j|j |j |jf2c}}tt}t|}d|d|d|d|d|d Scc}w)zGenerate setup.py content for building librt directly.

Uses build/librt-cache/ under the repo root (gitignored). The cache is keyed by a hash of sources and build environment, so it auto-invalidates when relevant factors change. Safe to call from multiple parallel pytest workers - uses file locking. Args: experimental: Whether to enable experimental features. opt_level: Optimization level ("0".."3") used when building librt.
