\u00c8 stato pubblicato il primo rilascio del progetto elfshaker, che sviluppa un sistema di gestione delle versioni per i file binari, ottimizzato per tenere traccia delle modifiche nei file eseguibili in formato ELF. Il sistema memorizza patch binarie tra i file e consente di estrarre la versione desiderata tramite una chiave, il che accelera notevolmente l'operazione di «git bisect» e riduce drasticamente lo spazio su disco utilizzato. Il codice del progetto \u00e8 distribuito con licenza Apache-2.0. <\/p>\n

Il programma si distingue per l'elevata efficienza nella memorizzazione delle modifiche binarie in un gran numero di file binari simili, ad esempio quelli ottenuti durante le 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 salvati in un unico 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 «git bisect» sul codice LLVM), permettendo di recuperare rapidamente la versione desiderata dei file eseguibili del progetto senza dover ricompilare dai sorgenti o tenere una copia di ogni versione del file eseguibile precedentemente compilato.
