Memory leak in Process(), Convert()

[rvishrm]

Hi, the following code is a simplified version of my code. Here, I'm trying to do some image processing on the image buffer.

package main

import	"github.com/h2non/bimg"

func resizeAndConvertImage(image []byte, height int, width int) ([]byte, error) {
		size, err := bimg.NewImage(image).Size()
		if err != nil {
			return nil, err
		}
	
		if width == 0 && height == 0 {
			width = size.Width
			height = size.Height
		}
	
	    options := bimg.Options{
			Width:  width,
			Height: height,
		}
		imgType := bimg.JPEG
		image, _ = bimg.NewImage(image).Process(options)
		image, _ = bimg.NewImage(image).Convert(imgType)
		return image, err
}

func main() {
	newImage, err := resizeAndConvertImage(imageBuffer, height, width)
}

I used a script for hitting so many requests to the server.

I started the script at 11:31 and stopped it at 11:38. It can be clearly seen that around 2GB of memory is stucked somewhere.

Then I tried commenting Process() and Convert() functions one by one.

//  image, _ = bimg.NewImage(image).Process(options)

//  image, _ = bimg.NewImage(image).Convert(imgType)

And graph showed around 1GB of memory leakage. (script start time is 11:53)

Then I commented both the function calls.

//  image, _ = bimg.NewImage(image).Process(options)
//  image, _ = bimg.NewImage(image).Convert(imgType)

And the memory graph shows that there is no memory leakage. Memory used is just in MBs.

Am I missing something obvious here?

I have also tried following options for the fix

   os.Setenv("GODEBUG", "madvdontneed=1")
	bimg.VipsCacheSetMax(0)
	bimg.VipsCacheSetMaxMem(0)
	os.Setenv("MALLOC_ARENA_MAX", "2")

Facing the same issue in process and convert function.

[fcuenca4]

have you tried setting MALLOC_ARENA_MAX=2 ?

Any solution for this?
