NAME App::BencherUtils - Utilities related to bencher VERSION This document describes version 0.241 of App::BencherUtils (from Perl distribution App-BencherUtils), released on 2018-04-03. SYNOPSIS DESCRIPTION This distribution includes several utilities: * bencher-code * bencher-for * bencher-module-startup-overhead * chart-bencher-result * cleanup-old-bencher-results * format-bencher-result * list-bencher-results * list-bencher-scenario-modules FUNCTIONS bencher_code Usage: bencher_code(%args) -> [status, msg, result, meta] Accept a list of codes and perform benchmark. % bencher-code 'code1' 'code2' is basically a shortcut for creating a scenario like this: { participants => [ {code_template=>'code1'}, {code_template=>'code2'}, ], } and running that scenario with "bencher". This function is not exported. Arguments ('*' denotes required arguments): * codes* => *array[str]* * precision => *float* * startup => *bool* (default: 0) Use code_startup mode instead of normal benchmark. * with_process_size => *bool* Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information. Return value: (any) bencher_for Usage: bencher_for(%args) -> [status, msg, result, meta] List distributions that benchmarks specified modules. This utility consults lcpan (local indexed CPAN mirror) to check if there are distributions that benchmarks a specified module. This is done by checking the presence of a dependency with the relationship "x_benchmarks". This function is not exported. Arguments ('*' denotes required arguments): * modules* => *array[perl::modname]* Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information. Return value: (any) bencher_module_startup_overhead Usage: bencher_module_startup_overhead(%args) -> [status, msg, result, meta] Accept a list of module names and perform startup overhead benchmark. % bencher-module-startup-overhead Mod1 Mod2 Mod3 is basically a shortcut for creating a scenario like this: { module_startup => 1, participants => [ {module=>"Mod1"}, {module=>"Mod2"}, {module=>"Mod3"}, ], } and running that scenario with "bencher". To specify import arguments, you can use: % bencher-module-startup-overhead Mod1 Mod2=arg1,arg2 which will translate to this Bencher scenario: { module_startup => 1, participants => [ {module=>"Mod1"}, {module=>"Mod2", import_args=>'arg1,arg2'}, ], } This function is not exported. Arguments ('*' denotes required arguments): * modules* => *array[perl::modargs]* * with_process_size => *bool* Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information. Return value: (any) chart_bencher_result Usage: chart_bencher_result(%args) -> [status, msg, result, meta] Generate chart of bencher result and display it. This function is not exported. Arguments ('*' denotes required arguments): * json* => *str* JSON data. Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information. Return value: (any) cleanup_old_bencher_results Usage: cleanup_old_bencher_results(%args) -> [status, msg, result, meta] Delete old results. By default it will only keep 1 latest result for each scenario for the same CPU and the same module versions. You can use "--dry-run" first to see which files would be deleted without actually deleting them. This function is not exported. This function supports dry-run operation. Arguments ('*' denotes required arguments): * detail => *bool* * num_keep => *int* (default: 0) Number of old results to keep. * query => *array[str]* * result_dir* => *str* Directory to store results files in. Special arguments: * -dry_run => *bool* Pass -dry_run=>1 to enable simulation mode. Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information. Return value: (any) format_bencher_result Usage: format_bencher_result(%args) -> [status, msg, result, meta] Format bencher raw/JSON result. This function is not exported. Arguments ('*' denotes required arguments): * json* => *str* JSON data. Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information. Return value: (any) list_bencher_results Usage: list_bencher_results(%args) -> [status, msg, result, meta] List results in results directory. This function is not exported. Arguments ('*' denotes required arguments): * detail => *bool* * exclude_scenarios => *array[str]* * fmt => *bool* Display each result with bencher-fmt. * include_scenarios => *array[str]* * latest => *bool* * module_startup => *bool* * query => *array[str]* * result_dir* => *str* Directory to store results files in. Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information. Return value: (any) list_bencher_scenario_modules Usage: list_bencher_scenario_modules(%args) -> [status, msg, result, meta] List Bencher scenario modules. This function is not exported. Arguments ('*' denotes required arguments): * detail => *bool* * query => *str* Returns an enveloped result (an array).
