问题描述
我有一个 python 脚本,它会遍历一堆 maya 文件并做一些事情.但是有时玛雅会出现段错误,我的脚本会停在那里.我尝试使用 signal 和 multiprocess.但都失败了.
I have a python script and it will loop through bunch of maya files and do some stuff. But some time maya get seg fault and my script will stop there. I tried with signal and multiprocess. But both failed.
import os, optparse, glob, json, signal import maya.standalone import maya.cmds as cmds from multiprocessing import Process, Queue def loadMayaBd(): maya.standalone.initialize(name='python') def sig_handler(signum, frame): print "segfault" def doSome(args, options): signal.signal(signal.SIGSEGV, sig_handler) loadMayaBd() #from here its just a example fileNameList = args[0] for eachFile in fileNameList: #this is throwing the seg fault #I want continue my for llop even if there is any segfault #I don't want to exit python coz of that segfault cmds.file(eachFile, force = 1, open = 1) if __name__ == "__main__": usage = "usage: %prog [options] args(file list)" parser = optparse.OptionParser(usage) parser.add_option("-l", "--log", dest="log", help="Log File Path", metavar="LOG_FILE") parser.add_option("-v", "--verbose", dest="verbose", help="Print All Logs", metavar="VERBOSE", default=False, action='store_true') (options, args) = parser.parse_args() if len(args) <= 0: errorMsg = "You must pass file path list for crawling" raise RuntimeError(errorMsg) p = Process(target=doSome, args=(args, options)) p.start() p.join()
有没有其他方法可以捕获 seg fault 并继续下一步?
Is there any other method which can trap seg fault and continue with next?
推荐答案
这对我有用:
import os import signal def sig_handler(signum, frame): print("segfault") signal.signal(signal.SIGSEGV, sig_handler) os.kill(os.getpid(), signal.SIGSEGV) while True: pass
您确定要在生成的每个进程中捕获段错误吗?
Are you sure you are trapping the segfault in each process that you are spawning?
