To test different wait behavior, override the wait_impl method. We want fork1() semantics -- only the forking thread survives in the child after a fork(). On some systems (e.g. Solaris without posix threads) we find that all active threads survive in the child after a fork(); this is an error. éN)Úsupport)Úthreading_helperigà?ic@s4eZdZdd„Zdd„Zdd„Zdd„Zd d „Zd S) ÚForkWaitcCs t ¡|_i|_d|_g|_dS)Nr)rZthreading_setupÚ_threading_keyÚaliveÚstopÚthreads)Úself©r ú'/usr/lib64/python3.10/test/fork_wait.pyÚsetUps zForkWait.setUpcCs8d|_|jD] }| ¡q d}|j ¡tj|jŽdS)Né)rrZjoinZclearrZthreading_cleanupr)rÚthreadr r r ÚtearDowns    zForkWait.tearDowncCs:|js6t ¡|j|<zt t¡Wqty4Yq0dS)N)rÚosZgetpidrÚtimeÚsleepÚ SHORTSLEEPZOSError)rZidr r r Úf's  z ForkWait.fcCstj||ddS)N©Úexitcode)rZ wait_process)rÚcpidrr r r Ú wait_impl/szForkWait.wait_implc Cs ttƒD]*}tj|j|fd}| ¡|j |¡qt  ¡t j }t |j ƒtkrjt d¡|t  ¡krBqjqBt|j  ¡ƒ}| |tttƒƒ¡|j  ¡}tjdvrªt ¡}nt ¡}|dkrút t¡d}|j D]}|j |||krÎ|d7}qÎt |¡n|j|dddS)N)ZtargetZargsgš™™™™™¹?)Z unixware7rr r)ZrangeÚ NUM_THREADSÚ threadingZThreadrZstartrZappendrZ monotonicrZ SHORT_TIMEOUTZlenrrZsortedZkeysZ assertEqualZlistZcopyÚsysZplatformrZfork1ZforkÚ LONGSLEEPZ_exitr) rZir ZdeadlineZaZ prefork_livesrZnZkeyr r r Ú test_wait2s.          zForkWait.test_waitN)Z__name__Z __module__Z __qualname__r rrrrr r r r rs  r)Z__doc__rrrZunittestrZtestrZ test.supportrrrrZTestCaserr r r r Zs
