Current Behavior

I checked connection with
socksify wget torproject.org
HTTP response 200 OK...
So the tor circuit works
Now I run
socksify session-desktop-linux-x86_64-1.16.1.AppImage
And the message I am trying to send keeps spinning, while on
sudo journalctl -f
I see following error continuously popping up:
Jun 01 17:42:43 linux kernel: traps: session-desktop[7933] trap int3 ip:55621c333295 sp:7ffda4ee42c0 error:0 in session-desktop-bin[556218207000+8976000]
The message never ends spinning so it doesn't seem to be able to connect via Tor proxy

This is the verbose output of the messenger (full output):

Steps To Reproduce

Install tor daemon and danted.client (which provides socksify script)
Run session in combination with the two with export SOCKS_SERVER=127.0.0.1:9050 (standard tor proxy)

Desktop Version

Linux linux 6.1.0-32-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.129-1 (2025-03-06) x86_64 GNU/Linux

Anything else?

I see it is written in python and I actually remember that python3 and dante socksify don't work well together

[mbondaru]

Okay, so after reading the source code it looks like in ts/mains/main_node.ts there's a following function:

function prepareURL(pathSegments: Array<string>, moreKeys?: { theme: any }) { 
  const urlObject: url.UrlObject = {
    pathname: join(...pathSegments),
    protocol: 'file:',
    slashes: true, 
    query: {
      name: packageJson.productName,
      locale: getCrowdinLocale(),
      version: app.getVersion(),
      commitHash: config.get('commitHash'),
      environment: (config as any).environment,
      node_version: process.versions.node,
      hostname: os.hostname(),
      appInstance: process.env.NODE_APP_INSTANCE,
      proxyUrl: process.env.HTTPS_PROXY || process.env.https_proxy,
      appStartInitialSpellcheckSetting,
      ...moreKeys,
    },     
  };
  return url.format(urlObject);
}

which expects an environment variable such as
export https_proxy="http://127.0.0.1:9050"
and that also doesn't seem to work with tor being enabled, all while
curl --socks5-hostname 127.0.0.1:9050 http://example.com
prints the html of the example page as expected

[mbondaru]

It seems that using a proxy such as socks with tor, requires a major rewrite that would issue web requests with SocksProxyAgent of 'socks-proxy-agent' dependency bundle rather than https.Agent that is currently being used in ts/session/apis/snode_api/onions.ts and ts/session/apis/seed_node_api/SeedNodeAPI.ts

Also, in countries where signal app is blocked, install and build are not possible with yarn as it keeps trying to download '@signalapp/better-sqlite3' package online, and was not possible to do even with yarn config set proxy. sqlcipher.tar.gz better be added to the files
