De eerste uitgave van het elfshaker-project is gepubliceerd, dat een versiebeheersysteem ontwikkelt voor binaire bestanden, geoptimaliseerd voor het bijhouden van wijzigingen in uitvoerbare bestanden in ELF-indeling. Het systeem slaat binaire patches tussen bestanden op, waarmee de gewenste versie op basis van een sleutel kan worden gehaald, wat de uitvoering van de operatie 'git bisect' aanzienlijk versnelt en de gebruikte schijfruimte sterk vermindert. De code van het project wordt verspreid onder de Apache-2.0-licentie. <\/p>\n

Het programma staat bekend om zijn hoge effici\u00ebntie in het opslaan van binaire veranderingen in een groot aantal vergelijkbare binaire bestanden, bijvoorbeeld verkregen tijdens incrementele builds van \u00e9\u00e9n project. In het bijzonder kunnen de resultaten van tweeduizend hercompilaties van de Clang-compiler (waarbij elke hercompilatie een verandering na elke commit weerspiegelt) worden opgeslagen in \u00e9\u00e9n pack-bestand van 100 MB, wat 4000 keer minder is dan wat nodig zou zijn bij aparte opslag. <\/p>\n

Het extraheren van een willekeurige toestand uit dit bestand duurt 2-4 seconden (60 keer sneller dan de operatie 'git bisect' op de LLVM-code), wat het mogelijk maakt om snel de benodigde versie van de uitvoerbare bestanden van het project te extraheren zonder opnieuw te bouwen vanuit de bronbestanden of een kopie van elke versie van het eerder gebouwde uitvoerbare bestand op te slaan.
