Hi,

First of all thank you for the great tool.
I've just tested it but got the error.
Possibly it's related to recursion in the code.

The command:

/home/bin/diff -fingerprint first_root.hdd.fingerprint -file root.hdd

The error:

runtime: goroutine stack exceeds 1000000000-byte limit

Hi,
Thanks for your feedback. May i know more details about the problem - platform, the file used for diff, version of golang?
I will try to take a look.
Please note that I am swamped with another project right now, so my response might be slow.
Regards
Monmohan

Ran into the same issue today. I'm running go version go1.8.2 linux/amd64 , and operating on large files (the two files to be diff'ed are approx 6GiB, the patch file is 290MiB.

Same issue with ~50MB files on go version go1.11.1 windows/amd64

Hi guys,
Can anyone share the files used? I would like to reproduce this

Hi!
I can provide You a file, but maybe You have it already. Do you by any chance have Dragonborn.esm from Skyrim Special Edition? I am trying to diff original and cleaned version. If You do not have it, let me know, I will upload it temporary somewhere.

Hi,
This is awesome, I was attempting to use bsdiff for this, but I think your application may be faster for creating diffs and less memory intensive???

I just ran into this error aswell. I can give you my configuration:

Using this image (its ~100MB) https://ipfs.io/ipfs/QmVLTMHtLRhnft3QspDx4qTJeXY6hiib1j77UfQmY54CGe/mosaic.png
I made a copy and made a few changes using Preview software on OSX
I then a) followed your example instructions, so I ran

$GOPATH/bin/fpgen -file ./moon.png && $GOPATH/bin/diff -fingerprint ./moon.png.fingerprint -file ./moon-to.png && $GOPATH/bin/patch -patch ./moon-to.png.patch -base ./moon.png

I also tried to use the example in the Godocs

package main

import (
	"os"

	"github.com/monmohan/xferspdy"
)

func main() {
	//Create fingerprint of a file
	fingerprint := xferspdy.NewFingerprint("./moon.png", 1024)
	//Say the file was updated
	//Lets generate the diff
	diff := xferspdy.NewDiff("./moon-to.png", *fingerprint)

	//diff is sufficient to recover/recreate the modified file, given the base/source and the diff.
	modifiedFile, _ := os.OpenFile("./moon-applied.png", os.O_CREATE|os.O_WRONLY, 0777)

	//This writes the output to modifiedFile (Writer). The result will be the same binary as /path/foo_v2.binary
	xferspdy.PatchFile(diff, "./moon.png", modifiedFile)

}

Go version go version go1.13.3 darwin/amd64
image

I received similar errors in both cases.

I wonder whether the issue is loading a large file into memory on the stack and the trick would either to be to load it onto the heap (short term fix?) Or read the file as a stream using somthing like mmap
Be great to hear if anyone fixe(s/d) this!
