Die erste Ausgabe des Projekts elfshaker wurde ver\u00f6ffentlicht. Es entwickelt ein Versionsverwaltungssystem f\u00fcr Bin\u00e4rdateien, das optimiert ist, um \u00c4nderungen in ausf\u00fchrbaren Dateien im ELF-Format nachzuverfolgen. Das System speichert bin\u00e4re Patches zwischen Dateien, erm\u00f6glicht das Abrufen der ben\u00f6tigten Version per Schl\u00fcssel und beschleunigt damit die Ausf\u00fchrung des \u201egit bisect\u201c-Befehls erheblich, wodurch der ben\u00f6tigte Speicherplatz deutlich reduziert wird. Der Code des Projekts wird unter der Lizenz Apache-2.0 verbreitet. <\/p>\n

Das Programm zeichnet sich durch hohe Effizienz bei der Speicherung bin\u00e4rer \u00c4nderungen in einer Vielzahl \u00e4hnlicher Bin\u00e4rdateien aus, die beispielsweise im Zuge inkrementeller Builds eines Projekts entstehen. Insbesondere k\u00f6nnen die Ergebnisse von zweitausend Neuerstellungen des Clang-Compilers (jede Neuerstellung spiegelt eine \u00c4nderung nach jedem Commit wider) in einer einzigen Pack-Datei gespeichert werden, die 100 MB gro\u00df ist \u2014 das ist 4000-mal weniger, als es bei der getrennten Speicherung erforderlich w\u00e4re. <\/p>\n

Das Abrufen eines beliebigen Zustands aus dieser Datei dauert 2\u20134 Sekunden (60 Mal schneller als der \u201egit bisect\u201c-Befehl bei LLVM-Code), was es erm\u00f6glicht, die ben\u00f6tigte Version der ausf\u00fchrbaren Dateien des Projekts schnell abzurufen, ohne den Quelltext neu zu kompilieren oder eine Kopie jeder zuvor erstellten ausf\u00fchrbaren Datei zu speichern.
