[英]Using RemoteDebugger to debug C# mono program on Raspberry Pi 3
[英]C# Mono program crashes on raspberry pi when auto executed
我们有一个在树莓派3上运行的C#mono程序。当我手动执行该程序时,该程序会完全执行,即sudo mono / pathtoexe,但是在从rc.local重新启动后执行(rc.local启动脚本文件, sudo / pathto .sh文件,该文件又通过sudo mono / paththexe启动应用程序),程序仅部分执行,日志中没有可见错误。
需要指出的是,我们要克服的测试用例是使应用程序在没有互联网的情况下运行,因为如果有互联网,它可以很好地运行(手动和自动启动都可以)
该PI是运行Raspbian版本8(Jessie)Mono JIT编译器版本3.2.8(Debian 3.2.8 + dfsg-10)的Raspberry PI 3。
这是rc.local文件:
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
printf "My IP address is %s\n" "$_IP"
fi
#echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
#hwclock -s
#sudo /etc/init.d/watchdog start&
sudo /home/pi/Vbox/./Main.sh&
#sudo /home/pi/Vbox/./Cmu.sh&
#/usr/bin/mono-service -p:/home/pi/Vbox /home/pi/Vbox/VboxV2.exe
sudo iwconfig wlan0 txpower off
#sudo mono /home/pi/Vbox/Vbox.exe
#sudo python /home/pi/Audio/audio_play.py
#iptables-restore < /etc/iptables.ipv4.nat
exit 0
这里要注意的主线是sudo /home/pi/Vbox/./Main.sh&
Main.sh文件是:
#!/bin/bash
Date=`date +%d_%m_%Y`
ErrorLogPath="/home/pi/LOG/GatewayWrapperError_$Date.log"
LogPath="/home/pi/LOG/GatewayWrapperLog_$Date.log"
## Fail over Block
function Failover
{
ErrorIn=$1
Datetime=`date +%d-%m-%Y:%H-%M-%S`
echo "Error: $1 Program"
printf "$Datetime: Error executing $ErrorIn program. Sending E-Mail notification \n">>$ErrorLogPath
echo "Error: notification"
#sudo mono --runtime=v4.0 /home/pi/EXE/Email.exe &
#wait
printf "$Datetime: Gateway notification sent \n">>$ErrorLogPath
#sudo wvdial 3gconnect &
#sleep 30
echo "wvdial run succed"
#sudo reboot
}
function main
{
## Executing Net_Connection_Program Core
# {(
# ExecutionDateTime=`date +%d-%m-%Y:%H-%M-%S`
# printf "$ExecutionDateTime: Net_Connect.sh started. \n">>$LogPath
# echo "Net_Connect Started"
# sudo /home/pi/Wrapper/./NetConnect.sh &
# #sudo /home/pi/Wrapper/./test.sh &
# )} ||
# {(
# Failover "Net_Connect_Core"
#)}
echo "Started"
## Executing Gateway Core
{(
ExecutionDateTime=`date +%d-%m-%Y:%H-%M-%S`
printf "$ExecutionDateTime: ES900G started. \n">>$LogPath
echo "ES900G Started"
sudo mono --runtime=v4.0 /home/pi/Vbox/VboxV2.exe &> /home/pi/LOG/GatewayWrapperLog_24_09_2018.log
)} ||
{(
Failover "Gateway_Core"
)}
}
##Master Call
main;
当程序通过脚本执行时,日志将在此时停止:
Function: Main Started
73574f
Vbox Version 1.0.0.0
ERROR: ConnectMQTT - Exception connecting to the broker
这是代码中的Main函数:
static void Main()
{
try
{
Thread.Sleep(5000);
Helper.WriteLine("Function: Main Started");
const string path = "/home/pi/Vbox/vboxid.txt";
VboxId = File.ReadAllText(path);
Console.WriteLine(VboxId);
Version = $"{Assembly.GetExecutingAssembly().GetName().Version}";
Helper.WriteLine($"Vbox Version {Version}");
CommMqttClient = null;
if (string.IsNullOrEmpty(VboxId)) return;
MQTT.ConnectMqtt(); //This is last error printed in the log shown above. The program seems to crash after this
Task.Factory.StartNew(VideoStorage.StartStorage);
Audio = new AudioPublicAnnouncement();
LiveStreaming = new VideoStreaming();
VideoRetrieve = new VideoRetrieve();
Console.ReadLine();
}
catch (Exception e)
{
Helper.WriteLine("Error - Main: " + e.Message, ConsoleColor.Red);
}
}
在上面的代码中,如果程序是手动执行的,则它可以工作。 那是我面临的主要问题。
请注意,这是由以前的代码维护者编写的,我是来解决此问题的。 他目前不可用,过去3天我一直在尝试解决此问题。 任何帮助将不胜感激。
谢谢,瓦伦
编辑:具有无限循环的最新代码,不会停止执行:
static void Main()
{
try
{
Thread.Sleep(5000);
Helper.WriteLine("Function: Main Started");
const string path = "/home/pi/Vbox/vboxid.txt";
VboxId = File.ReadAllText(path);
Console.WriteLine(VboxId);
Version = $"{Assembly.GetExecutingAssembly().GetName().Version}";
Helper.WriteLine($"Vbox Version {Version}");
CommMqttClient = null;
if (string.IsNullOrEmpty(VboxId)) return;
MQTT.ConnectMqtt();
Task.Factory.StartNew(delegate
{
MQTT.PublishMessage("REBOOT", $"VBOXID:{VboxId};VERSION:{Version};TIME:{DateTime.Now:dd-MM-yyyy HH-mm-ss};", false);
});
Task.Factory.StartNew(VideoStorage.StartStorage);
Audio = new AudioPublicAnnouncement();
LiveStreaming = new VideoStreaming();
VideoRetrieve = new VideoRetrieve();
while (true)
{
Thread.Sleep(1000);
}
}
catch (Exception e)
{
Helper.WriteLine("Error - Main: " + e.Message, ConsoleColor.Red);
}
}
我将此问题标记为已解决。 不幸的是,这与代码的执行方式有关。 详细信息在问题的最后编辑中。 @knocte是的,尽管这是一个跨500多个站点运行的生产系统,但我们需要尽早进行此操作,因此我们需要采取有计划和有计划的方法。 感谢您的所有投入。 非常感激。 干杯!
