L'entreprise Cloudflare a publi\u00e9 une analyse de l'un des plus grands incidents dans son infrastructure, qui a rendu une grande partie de son r\u00e9seau de distribution de contenu non op\u00e9rationnel pendant plus de 3 heures. La panne s'est produite apr\u00e8s un changement dans la structure de la base de donn\u00e9es h\u00e9berg\u00e9e dans ClickHouse, qui a fait doubler la taille du fichier contenant les param\u00e8tres pour le syst\u00e8me de lutte contre les bots. La base de donn\u00e9es a cr\u00e9\u00e9 des tables dupliqu\u00e9es, alors que la requ\u00eate SQL pour g\u00e9n\u00e9rer le fichier ex\u00e9cutait simplement une extraction de toutes les donn\u00e9es de toutes les tables par cl\u00e9, sans filtrer les doublons. SELECT name, type FROM system.columns WHERE table = 'http_requests_features' order by name;

\"La<\/center> <\/p>\n

Le fichier cr\u00e9\u00e9 s'est propag\u00e9 \u00e0 tous les n\u0153uds du cluster qui traite les requ\u00eates entrantes. Dans le gestionnaire qui utilise ce fichier pour d\u00e9tecter les acc\u00e8s des bots, les param\u00e8tres indiqu\u00e9s dans le fichier \u00e9taient stock\u00e9s en m\u00e9moire vive et, pour \u00e9viter une consommation excessive de m\u00e9moire, un limiteur de taille maximale du fichier a \u00e9t\u00e9 pr\u00e9vu dans le code. En conditions normales, la taille r\u00e9elle du fichier \u00e9tait bien inf\u00e9rieure \u00e0 cette limite, mais apr\u00e8s la duplication des tables, elle a d\u00e9pass\u00e9 le seuil. <\/p>\n

Le probl\u00e8me r\u00e9sidait dans le fait qu'au lieu de traiter correctement le d\u00e9passement de la limite et de continuer \u00e0 utiliser la version pr\u00e9c\u00e9dente du fichier, tout en informant le syst\u00e8me de surveillance de l'incident, le gestionnaire provoquait un arr\u00eat d'urgence, bloquant ainsi la transmission du trafic. L'erreur \u00e9tait caus\u00e9e par l'utilisation dans le code Rust de la m\u00e9thode unwrap() avec le type Result.

\"La<\/center> <\/p>\n

Lorsque la valeur Result a un \u00e9tat \u00ab Ok \u00bb, la m\u00e9thode unwrap() retourne l'objet associ\u00e9 \u00e0 cet \u00e9tat, mais si le r\u00e9sultat n'est pas un succ\u00e8s \u2014 l'appel conduit \u00e0 un plantage (le macro \u00ab panic! \u00bb est appel\u00e9). En g\u00e9n\u00e9ral, unwrap() est utilis\u00e9 lors du d\u00e9bogage ou lors de l'\u00e9criture de code de test et n'est pas recommand\u00e9 pour une utilisation dans des projets en production.
