Axel Rietschin, ingeni\u00f8r hos Microsoft, der arbejder med udviklingen af Windows-kernen, har s\u00e6ttede sp\u00f8rgsm\u00e5lstegn ved<\/a><\/noindex> muligheden for at udvikle operativsystemet ReactOS uden at l\u00e5ne kode fra Windows. If\u00f8lge ham har udviklerne af ReactOS benyttet koden fra Windows Research-kernen, hvis kildekoder blev licenseret til universiteter. L\u00e6kager af denne kode blev offentliggjort forskellige steder, herunder p\u00e5 GitHub.<\/p>\n

Rietschin er sikker p\u00e5, at det fysisk set er umuligt at skrive ReactOS-kernen fra bunden, som den ser ud i dag, udelukkende ved hj\u00e6lp af den tilg\u00e6ngelige offentlige dokumentation. Is\u00e6r matcher navnene p\u00e5 interne strukturer og funktioner i ReactOS-kernen med de tilsvarende navne i Windows Research-kernen, mens disse navne ikke eksporteres ved bygning og ikke vises noget sted undtagen i den originale kode. Det samme g\u00e6lder navne p\u00e5 makroer og parametre, hvis navne ikke kan reproduceres n\u00f8jagtigt uden at se p\u00e5 den originale Windows-kode.<\/p>\n

Lad os minde om, at der i 2006 blev opdaget<\/a><\/noindex> inklusiv omkring 100 linjer assemblerkode, som blev opn\u00e5et ved dekopilering af Windows. Efterf\u00f8lgende blev udviklingen pauset i omtrent en m\u00e5ned for at gennemf\u00f8re et revision af mulige overlappende elementer. Siden da har udviklerne af ReactOS v\u00e6ret s\u00e6rlig omhyggelige med at kontrollere de kildekoder, der tilbydes til inkludering i projektet. <\/p>\n

Ved tilbageg\u00e5ende engineering for at overholde amerikansk lovgivning vedr\u00f8rende ophavsret anvender ReactOS et dobbelt system, hvor \u00e9n forsker analyserer funktionerne og p\u00e5 basis heraf udarbejder dokumentation, mens en anden udvikler baserer sin nye implementering for ReactOS p\u00e5 denne dokumentation. Det er ikke usandsynligt, at der under analysen er blevet brugt kildekoder fra Windows, opn\u00e5et ved l\u00e6kager, og at de matchende funktions- og strukturnavne er blevet afspejlet i den udarbejdede dokumentation, men med den anvendte udviklingsmetode i ReactOS vil implementeringen v\u00e6re helt forskellig og skabt fra bunden.<\/p>\n

Desuden er der allerede , som tilf\u00f8jer en Just In Time Compiler til kernen \u2014 en overs\u00e6tter til at konvertere BPF bytecode til native<\/a><\/noindex> fakta<\/a><\/noindex> publikationer om fors\u00f8mmelse af kernesamlinger i NT og W2K med ufiltrerede fejlinformationsdata, der inkluderer navne p\u00e5 interne variabler. Mange navne p\u00e5 strukturer og funktioner findes ogs\u00e5 i headerfiler, der indg\u00e5r i SDK\/DDK, og strukturen for systemopkald kan bestemmes ved at analysere komponenter som COM runtime. Uden rensning af symbolske navnetabeller offentligg\u00f8res navne ofte i hotfix-opdateringer. Desuden bruger nogle programmer og drivere til Windows ikke-offentlige, udocumenterede opkald, og mange skjulte funktioner i Windows dukker op i l\u00f8bet af tilpasningen af opstart i virtualiseringssystemer og emulatorer.<\/p>\n

Udviklerne af ReactOS kunne anvende disse komponenter i deres omvendte ingeni\u00f8rarbejde.<\/p>\n
