Die erste Ausgabe des Projekts elfshaker wurde ver\u00f6ffentlicht, das ein Versionsverwaltungssystem f\u00fcr Bin\u00e4rdateien entwickelt, das f\u00fcr das Verfolgen von \u00c4nderungen an ELF-Format-Executables optimiert ist. Das System speichert bin\u00e4re Patches zwischen Dateien und erm\u00f6glicht die extrahierte Version anhand eines Schl\u00fcssels, was die Ausf\u00fchrung des Befehls \u201egit bisect\u201c erheblich beschleunigt und den ben\u00f6tigten Speicherplatz stark reduziert. Der Code des Projekts wird unter der Lizenz Apache-2.0 ver\u00f6ffentlicht. <\/p>\n

Das Programm zeichnet sich durch eine hohe Effizienz bei der Speicherung bin\u00e4rer \u00c4nderungen in einer gro\u00dfen Anzahl \u00e4hnlicher Bin\u00e4rdateien aus, zum Beispiel, die im Verlauf inkrementeller Builds eines Projekts erzeugt wurden. Insbesondere k\u00f6nnen die Ergebnisse von zweitausend Neubauten des Clang-Compilers (jede Neubau spiegelt eine \u00c4nderung nach jedem Commit wider) in einer einzigen Pack-Datei mit einer Gr\u00f6\u00dfe von 100 MB gespeichert werden, was 4000-mal weniger ist, als bei separater Speicherung erforderlich w\u00e4re. <\/p>\n

Das Abrufen eines beliebigen Zustands aus dieser Datei dauert 2-4 Sekunden (60 Mal schneller als der \u201egit bisect\u201c-Befehl f\u00fcr LLVM-Code), was es erm\u00f6glicht, die ben\u00f6tigte Version der Executable-Dateien des Projekts schnell abzurufen, ohne sie aus den Quelltexten neu kompilieren oder eine Kopie jeder fr\u00fcheren Version der Executable aufbewahren zu m\u00fcssen.
