linux下对拍器无法获得程序输出

[Alice-Zero]

ubuntu 16.04 python3,python2都试过了 好像停在了 compare.py:143 [x for x in map(do, programs)]这行 还请查看一下是我的问题还是新版对拍器的问题

Need more info

emm...原来是调试直接卡住了 稍微调试了一下，现在能跑出来了，但是对拍器只能获得std的输出，无法获得对拍程序的输出

from cyaron import *
while True:
    input_io=IO()
    input_io.input_writeln(randint(1, 100), randint(1, 100))
    Compare.program("./a", input=input_io, std_program="./std")

程序a和std都是A+B output:

Traceback (most recent call last):
  File "*/compare.py", line 5, in <module>
    Compare.program("./std", input=input_io, std_program="./std")
  File "*/python3.5/site-packages/cyaron/compare.py", line 144, in program
    [x for x in map(do, programs)]
  File "*/python3.5/site-packages/cyaron/compare.py", line 144, in <listcomp>
    [x for x in map(do, programs)]
  File "*/python3.5/site-packages/cyaron/compare.py", line 139, in do
    cls.__compare_two(program_name, content, std, grader)
  File "*/python3.5/site-packages/cyaron/compare.py", line 28, in __compare_two
    raise CompareMismatch(name, info)
cyaron.compare.CompareMismatch: ('./a', TextMismatch('0\n', '48\n', 'On line {} column {}, read {}, expected {}.', 1, 1, '0', '48'))

CentOS Linux release 7.5.1804 (Core) Ubuntu 16.04.4 LTS 这两个系统上使用python2和3都得到了同样的结果

def do(program_name):
    timeout = None
    if list_like(program_name) and len(program_name) == 2 and int_like(program_name[-1]):
        program_name, timeout = program_name
    with open(os.dup(input.input_file.fileno()), 'r', newline='\n') as input_file:
        if timeout is None:
        #调试发现这一行获得content总是'0\n'
            content = make_unicode(subprocess.check_output(program_name, shell=(not list_like(program_name)), stdin=input_file, universal_newlines=True))
        else:
            content = make_unicode(subprocess.check_output(program_name, shell=(not list_like(program_name)), stdin=input_file, universal_newlines=True, timeout=timeout))
    cls.__compare_two(program_name, content, std, grader)

@lin714093880 need fix?

[lin-toto]

Unable to reproduce in newest build. Check if you have 0.4.0.

[Alice-Zero]

emm...我再查看一下 ps:0.2.7运行正常，可能是我的设备对多线程不太支持

Bug confirmed in 0.3.2. Won't release a fix as 0.4.0 works
