Descrição
I’m working on a nice admin screen to config auto-logging of some common things (like wp_query in pre_get_posts and wp), and some other goodies.
To log things manually, you can use:
browser()->log ( $var, $label );
browser()->warn ( $var, $label );
browser()->info ( $var, $label );
browser()->error( $var, $label );
Also, commandas are chainable:
browser()->log( 'This is a log...' )->error( '...and this is an error' );
For example, to log all your main query’s query_vars:
add_filter( 'pre_get_posts', 'log_wp_query', 10000 );
function log_wp_query( $query ) {
if ( $query->is_main_query() )
browser()->log( $query->query_vars, 'pre_get_posts' );
return $query;
}
Filters
wplinb-match-wp-debug: Set to true to only log when wp_debug is true. To prevent logging when wp_debug is false:
add_filter( 'wplinb-match-wp-debug', '__return_true' );
wplinb-enabled: To disable logging completely. It takes precedence over wplinb-match-wp-debug. To disable logging:
add_filter( 'wplinb-enabled', '__return_false' );
Profiling
The plugin includes a really simple function to allow you to track execution time of different parts of your code.
browser()->timer( $key, $log = false );
The first time you call this function with a given $key (string) it will start a timer, and return false. You can start as many timers as you want, using different $key values. You can ignore the second parameter for this first call.
The second time you call this function with a given $key, it will return the ellapsed time in seconds since you started this $key timer. If you set the second parameter to true, it will also log this value to the browser.
Example 1: Sequential use, log manually.
browser()->timer( 'Mega loop' );
for ( $i = 0; $i < 1000000; $i++ ) {
//do something
}
$time = browser()->timer( 'Mega loop' );
browser()->log( $time, 'The mega loop took:' );
Example 2: Start and end in different places, log automatically.
add_action( 'posts_selection', 'start_timer', 100 );
add_filter( 'the_posts', 'end_timer', 1, 2 );
function start_timer( $query ) {
browser()->timer( 'Main query time' );
}
function end_timer( $posts, $query ) {
browser()->timer( 'Main query time', true );
return $posts;
}
This is not a good way of measuring how much time a query takes to run, it’s just to illustrate how to use the timer.
In exactly the same way, you can use the function
Browser()->memory( $key, $log = false );
to measure delta of memory consumption from your first call and your second call with the same $key.
Example:
Browser()->memory( 'testing' );
$test = array();
for ( $i = 0; $i < 100; $i++ ) {
$test[$i] = md5( rand( 1, $i ) );
}
Browser()->memory( 'testing', true );
Browser()->memory( 'testing' );
$test = array();
for ( $i = 0; $i < 10000; $i++ ) {
$test[$i] = md5( rand( 1, $i ) );
}
Browser()->memory( 'testing', true );
