Reset and save automatic information, Processing.

anthony20

Hello everyone

I have a problem with my application for processing. This increase the use of ram the computer until a few minutes after the program is blocked.

I think the system saves unnecessary data .

Is there any function or library with ability to reset the program and keep it only important data?

A greeting and Thanks so much

Hello,

I do not think that kind of library exist. Because how an algorithm could decided what is important or not in your code ? It's possible to change the maximum available memory in the processing's preferences. And you could optimise your code :)

I know that the memory can be Increased. But at the rate That grows in 20-30 minutes excede 2GB and not Consider It Appropriate to Overcome Those levels.

My thought was to reset the program every 15 minutes. And make a external saved, the values ​​of the variables. Furthermore, this would be very useful saved to avoid loss of information to anomalies.

I am new to programming and optimizing code seems complicated. I do not understand that exists both memory consumption.

The problem is that your message is quite generic...

Some programs use very little memory, others can eat all available memory quite quickly.

Finding where the memory is consumed can be delicate and in all cases, need the source to be examined. Sometime it is the normal behavior of the code (which can be improved to remove unnecessary data), sometime it is a memory leak (memory which should have been freed but isn't).

There are some tools helping in the diagnostic, but they suppose some good programming knowledge to use them effectively...

Now, indeed, you can save images or data to disk, free it, reload it later if you need it back. Processing can do that...

About the "automatic" part: no, Processing won't magically save "important" data and reset it. You have to find yourself what is important and takes lot of place, and save it yourself.

I have found parts of the program that is saturated. The minim library consumes about 30mb, by wave of data, for audio playback.

And the speech recognizer stt consumes about 0.5 mb / s of memory.

It would be very good for my program have a database with the values ​​of the variables to turn to. So no data would be lost when you close the program.

The problem is that I have no idea how I can do it.

    int dataa[] = {0, 0, 0, 0, 0, 0, 0, 0, 0}; 
    int datab[] = {0, 0, 0, 0, 0, 0, 0, 0, 0};
    int datac[] = {0, 0, 0, 0, 0, 0, 0, 0, 0};
    int datad[] = {0, 0, 0, 0, 0, 0, 0, 0, 0};
    int dataaa[] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0}; 
    int databb[] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
    int datacc[] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
    int datadd[] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0};

These are the only values ​​that range and I want to keep. How I can make a database to store and collect?

well, these lines can't really be the problem because they use very little space

but you can use saveStrings() and loadStrings()

it might help to post your code so we can have a look where the problem is, e.g. some people load images in draw() which is wrong

you can increase memory in the preferences as been said

there are ways to invoke a process of garbage collecting for the memory

Thank so much Chrisir

I was unaware of these functions for save and read data, I'm introducing them to my program and I will make backup of the data, for if dropped the program.

A pity that there is no saveInt (), I'll have to think about how to move from Int to string and back to int. salveBytes () I fall short.

The complete code of the program is very extensive (15,000 characters) I'm going to try to hang the parts that I think can cause problems.

Regards and thank you very much, has been very useful to me your answer.

I do not upload images in the draw(), but if sounds. Will that be the problem?

sonido = minim.loadFile("port disable" + ".mp3");

as I can fix this?

Chrisir

Make sonido a global var and load the file in setup(), pls. Thx.

anthony20

The sonido problem I've solved

As easy as putting sonido.close(); Before minim.loadFile

Now it remains to solve the problem with the voice recognizer.

This simple program consumes 0.5 mb / s of RAM.

import com.getflourish.stt.*;
import ddf.minim.*;
STT stt;
void setup() {
stt = new STT(this);
  stt.enableDebug();
  stt.setLanguage("es"); 
   stt.enableAutoRecord();
}
void draw() 
{}

Can you think of any solution?

anthony20

Good Morning

This code does not work well.

import com.getflourish.stt.*;
import ddf.minim.*;
STT stt;
byte a=1;
void setup() {


}
void draw() 

{

  reconoicer();
}

void reconoicer()
{a++;
  if(a==1){
  STT stt2;
  import ddf.minim.*;

stt2 = new STT(this);
stt2.enableDebug();
  stt2.setLanguage("es"); 
   stt2.enableAutoRecord();
stt2.setThreshold(50);
a=2;
stt2.getLineIn();
delay(200);
stt2.getMinimInstance();
  }}

I think the problem lies somewhere unseen object minim rate, generated by, the library stt.

Chrisir

I don't know stt

stt.enableAutoRecord();

Why?

Why not disable?

anthony20

It's better that way. The program is attentive and the microphone exceeds a certain value activates the voice recognizer.

If you remove it you have to use

stt.begin () and stt.end ();

The ram memory problem is not fixed in any of the forms.

Chrisir

there is still a lot of stuff that shouldn't be in draw() or in reconoicer() which gets called by draw().

import ddf.minim.*; you have that line before setup, so delete line 20.

STT stt2; before setup() pls

this in setup()

stt2 = new STT(this);
stt2.enableDebug();
  stt2.setLanguage("es"); 
   stt2.enableAutoRecord();
stt2.setThreshold(50);
stt2.getLineIn();
delay(200);
stt2.getMinimInstance();

and this stt2.enableAutoRecord(); : disable

remember that draw() (and therefore reconoicer() ) gets called 60 times per second and setup() runs only once. So all preparations must be in setup

Hi Chrisir

I spoke with Florian Schulz, he stt developer, and he has informed me that it is a problem of the library that is under investigation.

I think the fault is due to misuse of the minim library by the library stt. I think that makes a call to a variable type AudioPlayer and this is never closed. The java object reference remains and the garbage collector can not do anything.

I have informed the developer and see if he has time and can fix this.

Chrisir

i see!
