我已经使用Popen bash来运行命令行工具。 bash生成段错误或中止执行命令。
def FunctionToThread(args):
su2 = Popen('bash', shell = True, stdin = PIPE, stdout=fp, env = os.environ)
for i in commands:
su2.stdin.write(i)
su2.stdin.close()
su2.wait()
fp.close()
函数FunctionToThread使用线程模块进行线程化。如上所述,当在bash中遇到段错误时,线程终止。
我想要在try / except控件类型中捕获此段错误,最重要的是阻止我的线程终止。
我如何实现这一目标?

from multiprocessing import cpu_count
import threading
from subprocess import Popen, PIPE
import os
start =0
numcores = cpu_count()
global RESULTS, LOCK
LOCK = threading.Lock()
RESULTS = []
def ParallelRun(commands, RESULTS, LOCK):
for i in range(0, 100):
LOCK.acquire()
RESULTS.append('ParallelRUn')
LOCK.release()
su2 = Popen('bash', shell = True, stdin = PIPE, stdout=PIPE, env = os.environ)
for i in commands:
su2.stdin.write(i)
su2.stdin.close()
err =su2.wait()
for i in range(0, numcores):
commands = ['Enter commands which cause Segmentation Faults']
t = threading.Thread(target=ParallelRun, args=(commands, RESULTS, LOCK))
threads.append(t)
for t in threads:
t.start()
for t in threads:
t.join()
print len(RESULTS), RESULTS
要复制我的问题,请在命令列表中输入生成段错误的命令。
谢谢!

此问题已解决。事实证明,我在程序的if / else块中有一个 return 语句,它终止了我的帖子。
