Cloudflare'i ettev\u00f5te avaldas \u00fclevaate \u00fche oma infrastruktuuri suurima s\u00fcndmuse kohta, mille t\u00f5ttu j\u00e4i eile suur osa sisu edastusv\u00f5rgust t\u00f6\u00f6tuks enam kui 3 tunni jooksul. Rike toimus p\u00e4rast muutust ClickHouse'is talletatud andmebaasi struktuuris, mille tulemusena suurenes botivastase s\u00fcsteemi seadete fail kahe korra suuruseks. Andmebaasis tekkisid dubleeritud tabelid, kuna SQL-p\u00e4ring failide genereerimiseks lihtsalt v\u00e4ljastas k\u00f5ik andmed k\u00f5ikidest tabelitest v\u00f5tme j\u00e4rgi, ilma dubleeritud kirjeid filtreerimata. SELECT name, type FROM system.columns WHERE table = 'http_requests_features' order by name;

Loodud fail levis k\u00f5igisse klastrisse, mis t\u00f6\u00f6tleb sisenevaid p\u00e4ringuid. T\u00f6\u00f6tlejas, mis kasutab seda faili botide tuvastamiseks, salvestati failis m\u00e4\u00e4ratud parameetrid m\u00e4lus ja, et v\u00e4ltida liigset m\u00e4lu kasutamist, oli koodis kehtestatud maksimaalse failisuuruse piirang. Tavalistes tingimustes oli faili tegelik suurus oluliselt v\u00e4iksem m\u00e4\u00e4ratud piirangust, kuid p\u00e4rast tabelite duplitseerimist \u00fcletas see limiidi. <\/p>\n

Probleem seisnes selles, et asemel, et korrektselt k\u00e4sitleda piirangu \u00fcletamist ja j\u00e4tkata varasema versiooni faili kasutamist koos s\u00fcsteemi j\u00e4lgimise teavitamisega erakordsetest olukordadest, toimis t\u00f6\u00f6tleja h\u00e4daseisundi t\u00f5ttu, mis blokeeris edasise liikluse edastamise. Viga oli p\u00f5hjustatud Rusti keeles oleva koodi unwrap() meetodi kasutamisest Result t\u00fc\u00fcbi puhul.

Kui v\u00e4\u00e4rtus Result on olekus 'Ok', siis meetod unwrap() tagastab sellele olekule vastava objekti, kuid kui tulemus ei ole edukas, siis kutsub meetodi v\u00e4ljakutse esile kriitilise vea (k\u00e4ivitatakse makro 'panic!'). \u00dcldiselt kasutatakse unwrap() silumisprotsessis v\u00f5i testkoodi kirjutamisel ning seda ei soovitata kasutada tootmisprojektides.
