wait certain time when send data in mac os

[24seconds]

Description

There is a bug in rust-cli-pomodoro in mac os. When the number of deleted notifications are large, calling command history in ipc mode makes error.

Bug reproduce

1. Prepare two terminal tabs, let say terminal A and terminal B.
2. Run rust-cli-pomodoro app in terminal A.
3. Run pomodoro q -d 20 times in terminal B.
4. Run pomodoro history in terminal B.
5. You will see the error message

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 55, kind: Uncategorized, message: "No buffer space available" }'

Solution

According to the stackoverflow about this error, it says

On BSD systems sendto NEVER blocks, the docs are wrong. Mixed with some OSX specific problem when connected to high speed lans. Overall: Just don't think that sendto blocks, it doesn't on BSD. The good thing: If you know that, you can take this into account.

So I think maybe waiting for certain time can solve this problem and tried and it worked.
