Commencez par le point d’entrée du visualiseur de journaux et reproduisez le plantage avec un fichier journal contenant plus de 60 000 entrées. Inspectez la console du navigateur pour trouver l’erreur React signalée et déterminez si le visualiseur doit limiter les entrées ou les paginer ; la tâche est terminée lorsque les journaux volumineux s’affichent sans vider la page.

Description

1. to develop bug good first issue javascript
Steps to reproduce
  1. Set loglevel to in config/config.php to 0 ('loglevel' => 0).
  2. Execute many actions which will trigger a log message to get written.
  3. Open the log viewer when the logfile has more than 60000 entires.
Expected behaviour

The log viewer displays the log.

If the log is too big to be displayed, truncate to the newest n entries (where n is a value which can be handled by the frontend - for example 1000 or 5000) or paginate the log.

Actual behaviour

The log viewer crashes, so the page will get blank. It's not clear when exactly this happens. I have seen this with a logfile which counts about 62000 entries, but I believe the actual limit is lower and also depends on what browser and runtime environment you use.
