ERROR:LIVEUPDATE: Loaded manifest does not support current engine version (1.2.179)

Questions

Hi there, I’ve wanted to check my old test-project with live-update feature:

when trying to start download the manifest, I see:
ERROR:LIVEUPDATE: Loaded manifest does not support current engine version (1.2.179)
but nothing about this in manual, still see official example about it:

and 2nd question, about live-updating in HTML5:

Does it possible to find a solution to download resources from local directory of HTML5 build? not via remote link of ZIP or Amazon server. Sometimes I want to be sure that the files are loaded very quickly, and will not depend on remote servers.

Yes, we should make this fact clearer in the documentation.

As for testing content locally, I use this server script, that just serves the folder given to it as an argument:

cors_server.py

#!/usr/bin/env python3
# encoding: utf-8
"""Use instead of `python3 -m http.server` when you need CORS"""

import sys, socket
from http.server import HTTPServer, SimpleHTTPRequestHandler

hostname = socket.gethostname()
local_ip = '192.168.0.210'# socket.gethostbyname(hostname)

class CORSRequestHandler(SimpleHTTPRequestHandler):
    def end_headers(self):
        self.send_header('Access-Control-Allow-Origin', '*')
        SimpleHTTPRequestHandler.end_headers(self)

port = 8000
if len(sys.argv) > 1:
    port = int(sys.argv[1],10)

print("Listening on", local_ip, port)

httpd = HTTPServer((local_ip, port), CORSRequestHandler)
httpd.serve_forever()

And I also have a helper script to unpack and serve the latest defold.resourcepack_*.zip. It really helps testing a lot faster. It invokes the cors_server-pyscript. Feel free to make any changes necessary to make it work for your use case:

liveupdate.sh

#!/usr/bin/env bash

set -e

SCRIPTDIR=$(pwd)
DIR=./liveupdate

if [ -d "$DIR" ]; then
    rm -rf $DIR
    echo Removed $DIR
fi

ZIP=$(ls -t defold.resourcepack*.zip | head -1)

if [ "$ZIP" == "" ]; then
    echo "No resourcepack found!"
    exit 1
fi

echo "Found $ZIP"
ls -la $ZIP

unzip -q $ZIP -d $DIR
cp -v $ZIP $DIR/defold.resourcepack.zip

cp /Users/mawe/work/projects/users/denis.smirnov/issue-5499/liveupdate_version $DIR

(cd $DIR && python3 $SCRIPTDIR/cors_server.py)

EDIT: You can ofc use python -m http.server but then the 304 messages won’t be handled properly and it will always download the data.

May be I wrote my 2nd question wrong, but under “downloading from local directory of HTML5 build”,
I mean in production also, not for testing only.

let me describe the reason:
usually during making HTML5 games need to make sure the first scene loads very quickly, and then we can download resources (ogg files, assets of graphics later)
In Phaser (and other JS frameworks) it’s very easy to control and use, I want to be able to download resources “locally” in the web-build.
for example in case above, instead of:


just to write:
local URL_RESOURCES = '/resources/'

I’m not 100% sure what “locally” means here, but if it’s the current address of the page loaded, you can do this:

	if html5 then
		local url = html5.run('window.location.href')
		print("html5 url:", url)
	end

DEBUG:SCRIPT: html5 url: http://localhost:62860/html5/index.html

I think that the point is: why doesn’t the HTML5 debug build from IDE include live update resources? It’s hard to develop and to debug.

It is a fair question, and I don’t think we have a good answer for it.
We should definitely add it as an issue (if don’t already have it)

Added Issue 5593 for this.
