我被分配了以下任务。我们有一个二进制形式的预先构建的GUI,保存在$GAME_BIN
中。我必须写一个脚本,连接GUI和人工智能引擎。这是我的代码,非常自我描述。我们在这个例子中有:GAME_BIN=./sredniowiecze_gui
,ai1=./idle_ai.sh
,ai2=./idle_ai.sh
#!/bin/bash
# arguments parsing and setting $args - not posting this here
gui_outpipe=$(mktemp -u)
gui_inpipe=$(mktemp -u)
ai1_outpipe=$(mktemp -u)
ai1_inpipe=$(mktemp -u)
ai2_outpipe=$(mktemp -u)
ai2_inpipe=$(mktemp -u)
mkfifo $gui_outpipe $gui_inpipe $ai1_outpipe $ai1_inpipe $ai2_inpipe $ai2_outpipe
printinit 1 > $ai1_inpipe &
printinit 2 > $ai2_inpipe &
$GAME_BIN $args < $gui_inpipe &
$ai1 < $ai1_inpipe > $ai1_outpipe &
$ai1 < $ai2_inpipe > $ai2_outpipe &
while true; do
echo "Started the loop"
while true; do
read line < $ai1_outpipe || echo "Nothing read"
echo $line
if [[ $line ]]; then
echo "$line" > $gui_inpipe
echo "$line" > $ai2_inpipe
if [[ "$line" == "END_TURN" ]]; then
break
fi
fi
done
sleep $turndelay
while true; do
read line < $ai2_outpipe || echo "nothing read"
echo $line
if [[ $line ]]; then
echo "$line" > $gui_inpipe
echo "$line" > $ai2_inpipe
if [[ "$line" == "END_TURN" ]]; then
break
fi
fi
done
sleep $turndelay
done
wait
我创建了一个包含在idle_ai.sh
中的简单的空闲AI
#!/bin/sh
while true; do
echo END_TURN
done
然后,根本没有接收到来自GUI的END_TURN消息。另一方面,脚本没有接收到行END_TURN
中的第二个(*)
。如果我使用我自己编写的人工智能--非常长的代码,不在此发布,则在while循环的第二次运行中,将不会收到来自AI的任何信息。
我完全不知道如何调试它。
由于我不急于运行二进制文件,所以我将通过firejail ./game.sh [irrelevant parameters]
调用脚本
编辑在添加set -x
之后,输出是
INIT 10 3 1 1 1 3 9
+ [[ -n ./idle_ai.sh ]]
+ [[ -n '' ]]
+ [[ -n ./idle_ai.sh ]]
+ printinit 1
+ ./sredniowiecze_gui -human2
+ true
+ echo 'Started the loop'
Started the loop
+ true
+ read line
+ ./idle_ai.sh
+ echo 'INIT 10 3 1 1 1 3 9'
+ echo END_TURN
END_TURN
+ [[ -n END_TURN ]]
+ echo END_TURN
+ [[ END_TURN == \E\N\D\_\T\U\R\N ]]
+ break
+ true
+ read line
+ echo MOVE 5 9 5 8
MOVE 5 9 5 8
+ [[ -n MOVE 5 9 5 8 ]]
+ echo 'MOVE 5 9 5 8'
在AI对AI模式中:
INIT 10 3 1 1 1 3 9
+ [[ -n ./idle_ai.sh ]]
+ [[ -n ./idle_ai.sh ]]
+ printinit 1
+ printinit 2
+ ./sredniowiecze_gui
+ ./idle_ai.sh
+ true
+ echo 'Started the loop'
Started the loop
+ echo 'INIT 10 3 1 1 1 3 9'
+ true
+ read line
+ ./idle_ai.sh
+ echo 'INIT 10 3 2 1 1 3 9'
+ echo END_TURN
END_TURN
+ [[ -n END_TURN ]]
+ echo END_TURN
+ echo END_TURN
+ [[ END_TURN == \E\N\D\_\T\U\R\N ]]
+ break
+ sleep 1
+ true
+ read line
+ echo END_TURN
END_TURN
+ [[ -n END_TURN ]]
+ echo END_TURN
+ echo END_TURN
+ [[ END_TURN == \E\N\D\_\T\U\R\N ]]
+ break
+ sleep 1
+ true
+ echo 'Started the loop'
Started the loop
+ true
+ read line
EDIT2我做了建议的更改,现在我的代码是:
printinit 1 > $ai1_inpipe &
printinit 2 > $ai2_inpipe &
$GAME_BIN $args < $gui_inpipe &
$ai1 < $ai1_inpipe > $ai1_outpipe &
echo $!
$ai2 < $ai2_inpipe > $ai2_outpipe &
echo $!
while true; do
echo "Started the loop"
while true; do
read -u3 line || echo "Nothing read"
echo $line
if [[ $line ]]; then
echo "$line" > $gui_inpipe
echo "$line" > $ai2_inpipe
if [[ "$line" == "END_TURN" ]]; then
break
fi
fi
done
sleep $turndelay
while true; do
read -u4 line || echo "nothing read"
echo $line
if [[ $line ]]; then
echo "$line" > $gui_inpipe
echo "$line" > $ai1_inpipe
if [[ "$line" == "END_TURN" ]]; then
break
fi
fi
done
sleep $turndelay
done 3<$ai1_outpipe 4<$ai2_outpipe
现在脚本被卡在echo "$line" > $ai1_inpipe
行上了,尽管$ai2
进程仍然在运行。
EDIT3.现在使用set -x
的日志是
INIT 10 3 1 1 1 3 9
+ [[ -n ./idle_ai.sh ]]
+ [[ -n ./idle_ai.sh ]]
+ printinit 1
+ printinit 2
+ ./sredniowiecze_gui
+ echo 26
26
+ ./idle_ai.sh
+ echo 'INIT 10 3 1 1 1 3 9'
+ echo 27
27
+ ./idle_ai.sh
+ echo 'INIT 10 3 2 1 1 3 9'
+ true
+ echo 'Started the loop'
Started the loop
+ true
+ read -u3 line
+ echo END_TURN
END_TURN
+ [[ -n END_TURN ]]
+ echo END_TURN
+ echo END_TURN
+ [[ END_TURN == \E\N\D\_\T\U\R\N ]]
+ break
+ sleep 1
+ true
+ read -u4 line
+ echo END_TURN
END_TURN
+ [[ -n END_TURN ]]
+ echo END_TURN
+ echo END_TURN
如果在调用之前和之后添加一个echo FOO
,如下所示:
echo FOO
echo "$line" > $ai1_inpipe
echo BAR
然后执行echo FOO
,而不执行echo BAR
。

您使用的是read < input
,它吸收了所有输入,并且只使用第一行。不需要这样做,您应该从打开的文件描述符中读取read
,如下所示:
编辑:与用echo
写入fifo文件相同
while true; do
echo "Started the loop"
while true; do
read -u3 line || echo "Nothing read"
...
echo "$line" >&5
echo "$line" >&6
...
done
sleep $turndelay
while true; do
read -u4 line || echo "nothing read"
...
echo "$line" >&5
echo "$line" >&7
...
sleep $turndelay
done 3<$ai1_outpipe 4<$ai2_outpipe 5>$gui_inpipe 6>$ai2_inpipe 7>$ai1_inpipe
