NAME

Net::Twitter::Role::RetryOnError - Retry Twitter API calls on error

SYNOPSIS

     use Net::Twitter;
     $nt = Net::Twitter->new(
         traits      => ['API::REST', 'RetryOnError']
         max_retries => 3,
     );

DESCRIPTION

Temporary errors are not uncommon when calling the Twitter API. When applied to Net::Twitter this role will provide automatic retries of API calls in a very configurable way.

It only retries when the response status code is >= 500. Other error codes indicate a permanent error. If the maximum number of retries is reached, without success, an exception is thrown, as usual.

OPTIONS

This role adds the following options to "new":
initial_retry_delay
A floating point number specifying the initial delay, after an error, before retrying. Default: 0.25 (250 milliseconds).
max_retry_delay
A floating point number specifying the maximum delay between retries. Default: 4.0
retry_delay_multiplier
On the second and subsequent retries, a new delay is calculated by multiplying the previous delay by "retry_delay_multiplier". Default: 2.0
max_retries
The maximum number of consecutive retries before giving up and throwing an exception. If set to 0, it the API call will be retried indefinitely. Default 5.
retry_delay_code
A code reference that will be called to handle the delay. It is passed a single argument: a floating point number specifying the number of seconds to delay. By default, ``sleep'' in Time::HiRes is called.

If you're using a non-blocking user agent, like Coro::LWP, you should use this option to provide a non-blocking delay.
