Comments on 2020-02-16 Firefox syncserver

Hi Alex,

You can set a custom sync server amd token server in Firefox ios.

To access it:

Note that I haven’t done this, as I don’t (yet) have a sync server.

I get the feeling that this doesn’t work on the iPad... I get a bunch of extra options but no place where I can set the sync server URL.

I don’t know what to say to you. I set up my server in the way you described (except I didn’t set the last two options in the file)

I accessed the Advanced Settings in FFox on iPadOS. All works perfectly.

How weird. I just updated Firefox on the iPad and it does look different, but I still don’t know where to start. Do you feel like pasting a screenshot, or can you explain it like I’m super confused? Because I feel like I am!

  1. open Firefox on the iPad
  2. click hamburger menu
  3. scroll down until you see “Version 22.0 (17157)
  4. tap this section five time until the list of options changes
  5. now what?

At the top, I see three items:

  1. my email address and a note saying I need to enter my password (but since I deleted my account, clicking on this item just takes me to accounts.firefox.com where I could probably recreated my account and start sync immediately but with their servers)
  2. error diagnosis: ask for an upgrade (translating from German)
  3. error diagnosis: forgot sync-status (translating from German)

No other item in these settings seem related to sync. What am I not seeing?

After you tap the section until the lost of options changes, there should be a new menu item at the top of the Preferences under “Firefox Account” called “Advanced Sync Settings”.

In that modal dialog you can set the address of your sync server, in the form https://example.com/sync/token/1.0/sync/1.5

I didn’t create a FFox account until after I’d created my sync server.

Oh wow, I just tried it on the iPhone and it worked. Tapped on the Version five times, it automatically scrolls to the top showing me the things I listed previously, but now I scroll back to the bottom and do it again and now I see new items at the top:

  1. Sign in to Sync
  2. Advanced Sync Settings
  3. Debug: use stage servers

Hah, thanks for pointing me at it again. I might give this another try.

Well, I think it’s working:

Firefox on iOS Advanced Sync Settings Firefox on iOS Advanced Settings

On the iPad, the situation was different. I had to do the following:

  1. log into sync even though I couldn’t change the sync server and Firefox synced with the default sync server
  2. log out of sync
  3. activate the advanced settings again
  4. now you can change the sync server
  5. log into sync again

🙄

I’m looking at Run your own Sync-1.5 Server right now and I’m wondering about the WSGI setup. Are you using it?

I guess I don’t need to use it as my setup is basically Apache + Gunicorn. 😀

Except have to turn on force_wsgi_environ. As far as I can see in the Apache documentation on Reverse Proxy Request Headers but then again, the nginx setup instructions mention X-Forwarded-Proto and X-Real-IP, both of which the Apache docs don’t mention. Gaaaaah! 😭

Setup for Monit:

check process syncserver matching syncserver
    start program = "/bin/bash -c '(cd /home/alex/src/syncserver && exec /usr/bin/make serve 2&>1 syncserver.log)' &"
    stop program = "/usr/bin/killall gunicorn"
    if failed
	host alexschroeder.ch
	port 443
	type tcpssl
	protocol http
	request "/sync"
	for 5 cycles
	then restart
    if totalmem > 100 MB for 5 cycles then restart
    if 3 restarts within 15 cycles then stop

I don’t remember seeing any error messages about OAuth. In fact, I don’t remember seeing any errors at all. It was all silent fails.
