Compania Cloudflare a publicat o analiz\u0103 a uneia dintre cele mai mari incidente din infrastructura sa, din cauza c\u0103ruia ieri o mare parte din re\u021beaua de livrare a con\u021binutului a fost inoperabil\u0103 timp de peste 3 ore. Defectul a ap\u0103rut dup\u0103 o modificare \u00een structura Bazei de Date, stocat\u0103 \u00een ClickHouse, dup\u0103 care fi\u0219ierul cu parametrii pentru sistemul de combatere a bot-urilor s-a dublat \u00een dimensiune. \u00cen Baza de Date s-au format tabele duplicat, \u00een condi\u021biile \u00een care interogarea SQL pentru generarea fi\u0219ierului pur \u0219i simplu af\u0219a toate datele din toate tabelele prin cheie, f\u0103r\u0103 a elimina duplicatele. SELECT name, type FROM system.columns WHERE table = 'http_requests_features' order by name;

Fi\u0219ierul creat s-a propagat prin toate nodurile cluster-ului care proceseaz\u0103 cererile de intrare. \u00cen handlerul care folose\u0219te acest fi\u0219ier pentru a verifica solicita\u021biile de la bo\u021bi, parametrii specifica\u021bi \u00een fi\u0219ier erau salva\u021bi \u00een memoria RAM, iar pentru a proteja \u00eempotriva consumului excesiv de memorie, \u00een cod a fost prev\u0103zut un limitator pentru dimensiunea maxim\u0103 permis\u0103 a fi\u0219ierului. \u00cen condi\u021bii normale, dimensiunea real\u0103 a fi\u0219ierului era semnificativ mai mic\u0103 dec\u00e2t limita impus\u0103, dar dup\u0103 duplicarea tabelelor a dep\u0103\u0219it limita. <\/p>\n

Problema a fost c\u0103, \u00een loc s\u0103 fie tratat\u0103 corect dep\u0103\u0219irea limitei \u0219i s\u0103 se continue utilizarea versiunii anterioare a fi\u0219ierului, inform\u00e2nd sistemul de monitorizare despre situa\u021bia de urgen\u021b\u0103, \u00een handler se activa \u00eenchiderea for\u021bat\u0103, care bloca continuarea traficului. Eroarea a fost cauzat\u0103 de utilizarea \u00een codul scris \u00een Rust a metodei unwrap() cu tipul Result.

\"Defec\u021biunea<\/center> <\/p>\n

C\u00e2nd valoarea Result are starea \u201eOk\u201d, metoda unwrap() returneaz\u0103 obiectul asociat acestei st\u0103ri, dar dac\u0103 rezultatul nu este de succes \u2014 apelul duce la o terminare de urgen\u021b\u0103 (se activeaz\u0103 macro-ul \u201epanic!\u201d). De obicei, unwrap() este folosit \u00een procesul de depanare sau \u00een scrierea codului de testare \u0219i nu este recomandat pentru utilizarea \u00een proiecte de produc\u021bie.
