Perinci::Sub::Property::retry - Specify automatic retry

VERSION

This document describes version 0.10 of Perinci::Sub::Property::retry (from Perl distribution Perinci-Sub-Property-retry), released on 2016-05-11.

SYNOPSIS

# in function metadata
retry => 3,

# more detailed
retry => {n=>3, delay=>10, success_statuses=>/^(2..|3..)$/},

DESCRIPTION

This property specifies retry behavior.

Values: a hash containing these keys:

  • n => INT (default: 0)

    Number of retries, default is 0 which means no retry.

  • delay => INT (default: 0)

    Number of seconds to wait before each retry, default is 0 which means no wait between retries.

  • success_statuses => REGEX (default: '^(2..|304)$')

    Which status is considered success.

  • fatal_statuses => REGEX

    If set, specify that status matching this should be considered fatal and no retry should be attempted.

  • non_fatal_statuses => REGEX

    If set, specify that status not matching this should be considered fatal and no retry should be attempted.

  • fatal_messages => REGEX

    If set, specify that message matching this should be considered fatal and no retry should be attempted.

  • non_fatal_messages => REGEX

    If set, specify that message not matching this should be considered fatal and no retry should be attempted.

Property value can also be an integer (specifying just 'n').

If function does not return enveloped result (result_naked=0), which means there is no status returned, a function is assumed to fail only when it dies.

This property's wrapper implementation currently uses a simple loop around the eval block.

It also pass a special argument to the function -retries so that function can be aware about retries.
