Feature: "Reset time" option for tries

[skrabadiloseidon]

Some kind of "reset time" option for tries would be nice.
When this option is set it should reset the tries count back to 0.
Why could this be useful?

I wrote a script that connects to a mysql server, sometimes i need to restart the server, so i wrapped my code with this gem.
When the server is restarting, a exception is raised, then it waits 10 seconds, the server is online again end everything is fine,
except i restart the server multiple times a week then the tries count is reached an the script stops.
but if i could define a timeout after the tries count is resetted this would work perfect.

sorry for my bad english, i hope you can understand what i mean.

I'm not sure I fully understand your message.
Can you provide some code samples?

I try to explain it with art of pseudo code:

loop do
  Retryable.retryable(tries: 3, sleep: 10) times do
    mysql.insert("data")
  end
end

• I run the code, now i restart the mysql server, the mysql.insert code raises an exception => tries +1
• The server ist back online, mysql.insert ist working again
• Next day in need to restart the mysql server again => mysql.insert exception => tries +1
• Next day the same=> tries +1 => tries is now 3 => script ends

Now my idea: An option to tell retryable: retry this 3 times. after x seconds reset tries back to 0, so i have 3 tries again.

Failure example: Mysql server is restarted in 10 seconds => short problem, tries resetted, script working again
Failure example: Mysql server crashed because hdd full => long problem, more then x tries in x seconds => no reset, script ends and raises final exception

Wouldn't a combination of :not option + retries count comparison solve this use case?

https://github.com/nfedyashev/retryable#matching-error-messages - that's how you can check how many tries did it make.
If it is above a certain threshold raise a custom exception that's listed in :not array - https://github.com/nfedyashev/retryable#specify-exceptions-where-a-retry-should-not-be-performed
