Bot does not recover properly when using infinity_polling · Issue #1058 · eternnoir/pyTelegramBotAPI · GitHub

  1. What version of pyTelegramBotAPI are you using? 3.7.4

  2. What OS are you using? Raspbian

  3. What version of python are you using? 3.6.9

Testing out bot.infinity_polling() as recommended in #1057 I noticed a bug in the recovery from exceptions:

It seems like the bot does not recover completely from a collision from another bot instance. It crashes and restarts successfully, which is nice, but it seems to get stuck in a restart loop every 3s (sleep time on recovery). I would guess there is an implicit state that carries over the restart that still contains the cancel instruction, but I haven't found anything obvious.

This bug can be bypassed by not starting another instance with the same token, but I assume that the same bug will also strike with other exceptions, unrelated to this cause.

Reproduction:

  1. Start instance 1 with bot.infinity_polling() and logging.INFO
  2. Start another instance to provoke a collision
  3. stop second bot to allow instance 1 to run
  4. -> instance 1 has crashed and is stuck in restart loop afterwards
