NAME

Perinci::Examples::Tx - Examples for using transaction

VERSION

This document describes version 0.824 of Perinci::Examples::Tx (from Perl distribution Perinci-Examples), released on 2023-07-09.

FUNCTIONS

check_state

Usage:

 check_state() -> [$status_code, $reason, $payload, \%result_meta]

Return 'check_state' if checking state, otherwise empty string.

This function is not exported.

This function is idempotent (repeated invocations with same arguments has the same effect as single invocation). This function supports transactions.

No arguments.

Special arguments:

  • -tx_action => str

    For more information on transaction, see L<Rinci::Transaction>.

  • -tx_action_id => str

    For more information on transaction, see L<Rinci::Transaction>.

  • -tx_recovery => str

    For more information on transaction, see L<Rinci::Transaction>.

  • -tx_rollback => str

    For more information on transaction, see L<Rinci::Transaction>.

  • -tx_v => str

    For more information on transaction, see L<Rinci::Transaction>.

Returns an enveloped result (an array).

First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.

Return value: (any)

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
