Class: ProfileSection - X-Ref
Class for handling function-scope profiling| __construct( $name ) X-Ref |
| Begin profiling of a function and return an object that ends profiling of the function when that object leaves scope. As long as the object is not specifically linked to other objects, it will fall out of scope at the same moment that the function to be profiled terminates. This is typically called like: <code>$section = new ProfileSection( __METHOD__ );</code> param: string $name Name of the function to profile |
| __destruct() X-Ref |
| No description |
| __construct( array $params ) X-Ref |
param: array $params |
| instance() X-Ref |
| Singleton return: Profiler |
| setInstance( Profiler $p ) X-Ref |
| Set the profiler to a specific profiler instance. Mostly for dumpHTML param: Profiler $p |
| setProfileID( $id ) X-Ref |
param: string $id |
| getProfileID() X-Ref |
return: string |
| transactionWritingIn( $server, $db, $id = '' ) X-Ref |
| Mark a DB as in a transaction with one or more writes pending Note that there can be multiple connections to a single DB. param: string $server DB server param: string $db DB name param: string $id Resource ID string of connection |
| transactionWritingOut( $server, $db, $id = '' ) X-Ref |
| Mark a DB as no longer in a transaction This will check if locks are possibly held for longer than needed and log any affected transactions to a special DB log. Note that there can be multiple connections to a single DB. param: string $server DB server param: string $db DB name param: string $id Resource ID string of connection |
| setTemplated( $t ) X-Ref |
| Mark this call as templated or not param: bool $t |
| getTime( $metric = 'wall' ) X-Ref |
| Get the initial time of the request, based either on $wgRequestTime or $wgRUstart. Will return null if not able to find data. param: string|bool $metric Metric to use, with the following possibilities: return: float|null |
| getInitialTime( $metric = 'wall' ) X-Ref |
| Get the initial time of the request, based either on $wgRequestTime or $wgRUstart. Will return null if not able to find data. param: string|bool $metric Metric to use, with the following possibilities: return: float|null |
| debug( $s ) X-Ref |
| Add an entry in the debug log file param: string $s String to output |
| debugGroup( $group, $s ) X-Ref |
| Add an entry in the debug log group param: string $group Group to send the message to param: string $s String to output |
Class: TransactionProfiler - X-Ref
Helper class that detects high-contention DB queries via profiling calls| transactionWritingIn( $server, $db, $id ) X-Ref |
| Mark a DB as in a transaction with one or more writes pending Note that there can be multiple connections to a single DB. param: string $server DB server param: string $db DB name param: string $id ID string of transaction |
| recordFunctionCompletion( $method, $realtime ) X-Ref |
| Register the name and time of a method for slow DB trx detection This method is only to be called by the Profiler class as methods finish param: string $method Function name param: float $realtime Wal time ellapsed |
| transactionWritingOut( $server, $db, $id ) X-Ref |
| Mark a DB as no longer in a transaction This will check if locks are possibly held for longer than needed and log any affected transactions to a special DB log. Note that there can be multiple connections to a single DB. param: string $server DB server param: string $db DB name param: string $id ID string of transaction |
| wfGetRusage() X-Ref |
| Get system resource usage of current request context. Invokes the getrusage(2) system call, requesting RUSAGE_SELF if on PHP5 or RUSAGE_THREAD if on HHVM. Returns false if getrusage is not available. return: array|bool Resource usage data or false if no data available. |
| wfProfileIn( $functionname ) X-Ref |
| Begin profiling of a function param: string $functionname Name of the function we will profile |
| wfProfileOut( $functionname = 'missing' ) X-Ref |
| Stop profiling of a function param: string $functionname Name of the function we have profiled |
