In which cases updatesTooLong sends #2754

Closed glcanvas closed 9 months ago

glcanvas commented 9 months ago

Hello! Reading Telegram documentation https://core.telegram.org/api/updates

I'm trying to fetch latest messages from channel, and I'm not interested in outdated (old) messages. I.e. in messages which posted more than 2-3 seconds ago.

Have some questions: 1) Notice these constructor: https://core.telegram.org/constructor/updatesTooLong

In which cases these command will be sent to client? Am I right this happens during huge delay on a server side, or if in one moment more than 1_000 events occurred?

2) Is it possible to skip updatesTooLong and continue to listen actual information? Will new updates be sent to client from server side after updatesTooLong event? For me it's ok to skip some messages, much more important to get latest messages.

It is documentation for main Telegram API, unrelated to TDLib API.

updatesTooLong is unrelated to channel updates. It is also unspecified when the update is sent. Apps like TDLib must just handle it and fetch missed updates if appropriate.

Yes, agreed, this question unrelated to TDLib API, But thought you may have more information about this.

It is also unspecified when the update is sent

Got it, thank you!
