Les tâches Cron régulières de la ferme
1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.

Nodejs spawn - child processes
24 février 2019, par z EyelandMy nodejs application is running on raspberry Pi. The program uses spawn child process to trigger bash scripts which record or compress the previous recorded file. The program records fine. After recording the user selects the compress button. This kills the recording spawn process and fires the bash script for compression. The issue I am having is that whenever the video length gets around 1min long the compression spawn process times out or something. I ran ps -ef to view all process and i noticed that the compression script is still there. She the video length is short - the compression spawn process completes its cycle and send api request to shutdown the process. Here is some code
Api with console log that lets me know when compression is done. When the video clips are longer around 1min this GET request never logs’=
app.get('/clovis/api/led', function (req, res){
console.log("api activated for resetLED function");
resetLED();
console.log("reset was completed");
})Nodejs spawns that call different bash scripts
function setBashScript(scriptNum){
if(scriptNum == 0){
//do this
child = spawn('./feedmpeg.sh');
resetLED();
}
if(scriptNum == 1){
//do this
updatePicturePath();
child = spawn('./feedSnapshot.sh',[pictureFilePath]);
resetLED();
}
if(scriptNum == 2){
//do this
updateVideoPath();
child = spawn('./feedmpegRecord.sh',[videoFilePath]);
isRecording = true;
resetLED();
ledRed();
}
if(scriptNum == 10){
//do this
updateCompressedPath();
child = spawn('./generalCompressionMP4.sh',[videoFilePath,compressedFilePath]);
isRecording = false;
resetLED();
ledBlue();
}
}generalCompressionMP4.sh - The spawn process that doesnt complete if video length is too long. Generally when the process is complete, I head over to the localhost server and view the mp4 file. When this issue occures the mp4 doesnt load, the old path is not removed, and the api doesnt send.
#!/bin/bash
FILEPATH="$1"
COMPRESSIONPATH="$2"
ffmpeg -i $FILEPATH -vcodec h264 -acodec mp2 $COMPRESSIONPATH
sudo rm $FILEPATH
curl -H "Content-Type: application/json" -X POST
http://localhost:3000/clovis/api/ledWhy might the process get stuck ? How can i fix this ? Should I not use spawn child process ?
