Use multiple accounts (Airgram instances) with TdLib

[volodalexey]

Issue type:

[x] question

Airgram version:

[x] 2.3.0

TDLib version:

[x] 1.5.0

Steps to reproduce or a small repository showing the problem:

How can I run Airgram as a bot and Airgram as a user at the same time?
If I use this (the same apiId and apiHash):

import { Airgram, Auth } from 'airgram';

const apiId = '...';
const apiHash = '...';
const tdLibPath = '...';

const airgramUser = new Airgram({
  apiId,
  apiHash,
  command: tdLibPath,
  databaseDirectory: '.../userdb',
  logVerbosityLevel: 2,
});

airgramUser.use(
  new Auth({
      phoneNumber: '...',
      code: '...',
  }),
);

const airgramBot = new Airgram({
  apiId,
  apiHash,
  command: tdLibPath,
  databaseDirectory: '.../botdb',
  logVerbosityLevel: 2,
});

airgramBot.use(
  new Auth({
      token: '...'
  }),
);

const userInfo = await airgramUser.api.getMe();
const botInfo = await airgramBot.api.getMe();

I get an error:

[ 0][t 0][1580065911.360865116][Client.cpp:272]	Check `!is_locked` failed

I see that this is possible here

One TDLib Client can manage only one account, but there is no limit on number of clients that can be created in one process. So you can create as much TDLib Clients as you want and initialize them with different database and file folders for different accounts.

Each Airgram instance creates new TDLib client. Perhaps it is not a cause of the error. Have you seen this issue?

I do not know why, but migration to the version 3.0.2 solved this issue too. Thanks
