26 | * To primary APIs for this feature, and the classes where their documentation |
27 | * starts, are: |
28 | * |
29 | * - MediaWiki\Logger\LoggerFactory, this creates all logger objects at |
30 | * run time. |
31 | * |
32 | * - MediaWiki\Logger\Spi, to develop or configure the service classes |
33 | * that internally create logger objects. For example, MediaWiki\Logger\LegacyLogger |
34 | * is the default Spi that backs features like $wgDebugLogFile. |
35 | * MediaWiki\Logger\MonologSpi is an Spi you can opt-in to via $wgMWLoggerDefaultSpi |
36 | * to enable structured logging with destinations like Syslog and Logstash, |
37 | * and "processor" and "formatter" features to augment messages with metadata, |
38 | * as powered by the Monolog library. |
39 | * |
40 | * - MWDebug, the logic behind $wgDebugToolbar. |
41 | * |

45 | /** |
46 | * Service provider interface to create \Psr\Log\LoggerInterface objects. |
47 | * |
48 | * MediaWiki can be configured to use a class implementing this interface |
49 | * via the $wgMWLoggerDefaultSpi configuration variable. |
50 | * |
51 | * This configuration is consumed by MediaWiki\Logger\LoggerFactory, which is |
52 | * where we create logger objects. |
53 | * |
54 | * While not recommended in production code, you can construct and install |
55 | * an Spi class at runtime via MediaWiki\Logger\LoggerFactory::registerProvider |
56 | * (e.g. to power debug features in PHPUnit bootstrapping, or Maintenance |
57 | * scripts). |
