[英]Timeout child thread for python3
I am quite new to programming and I am running Linux, python3.5我对编程很陌生,我正在运行 Linux,python3.5
There are a few similar questions in Stack Overflow but most of them do not have any response Stack Overflow 中也有一些类似的问题,但大部分都没有任何回应
like: [Python 2.7 multi-thread]In Python, how to timeout a function call in sub-thread? like: [Python 2.7 多线程]在Python中,如何使子线程中的函数调用超时? , and Python , Timeout on a function on child thread without using signal and thread.join , 和Python , 子线程上的函数超时而不使用信号和 thread.join
I am able to use signal when it is in main thread and timeout for multiprocess.当信号在主线程和多进程超时时,我可以使用它。 However, the function I am currently running is a child thread using apscheduler (or it can be started directly)但是,我目前运行的函数是使用apscheduler的子线程(也可以直接启动)
schedule.add_job(test_upload.run, 'interval', seconds=10, start_date='2016-01-01 00:00:05',
args=['instant'])
and I can't convert it to child process because I am sharing database connection.而且我无法将其转换为子进程,因为我正在共享数据库连接。
I have also tried https://stackoverflow.com/a/36904264/2823816 , but terminal said我也试过https://stackoverflow.com/a/36904264/2823816 ,但终端说
result = await future.result(timeout = timeout)
^
SyntaxError: invalid syntax
in在
import concurrent
def run():
return 1
timeout = 10
with concurrent.futures.ThreadPoolExecutor(max_workers=1) as executor:
future = executor.submit(run) # get a future object
try:
result = await future.result(timeout = timeout)
except concurrent.futures.TimeOutError:
result = None
I am now very sure how to solve it:( Thanks for any help.我现在非常确定如何解决它:(感谢您的帮助。
I gave up timing out the thread in my child thread.我放弃了子线程中的线程超时。
So I used multi-process within the child thread to kill it.所以我在子线程中使用了多进程来杀死它。 I could not find any other solution.我找不到任何其他解决方案。
