Pubblicato il primo rilascio del progetto elfshaker, che sviluppa un sistema di gestione delle versioni per file binari, ottimizzato per il tracciamento delle modifiche nei file eseguibili in formato ELF. Il sistema memorizza patch binari tra i file, consente di estrarre la versione desiderata tramite chiave, accelerando notevolmente l'operazione \u00abgit bisect\u00bb e riducendo significativamente lo spazio su disco utilizzato. Il codice del progetto \u00e8 distribuito con licenza Apache-2.0. <\/p>\n

Il programma \u00e8 notevole per l'alta efficienza nella memorizzazione di modifiche binarie in un gran numero di file binari simili, ad esempio, quelli ottenuti durante il processo di build incrementali di un singolo progetto. In particolare, i risultati di duemila ricompilazioni del compilatore Clang (ogni ricompilazione riflette una modifica dopo ogni commit) possono essere conservati in un file pack di 100 MB, che \u00e8 4000 volte pi\u00f9 piccolo rispetto a quanto sarebbe necessario per la memorizzazione separata. <\/p>\n

L'estrazione di qualsiasi stato da questo file richiede 2-4 secondi (60 volte pi\u00f9 veloce dell'operazione \u00abgit bisect\u00bb sui codici LLVM), consentendo di estrarre rapidamente la versione desiderata dei file eseguibili del progetto senza ricompilare dai sorgenti o memorizzare una copia di ciascuna versione precedente del file eseguibile.
