+ Use hash table for finding identical chunks, speeding up process
considerably
+ Add test case to verify that identical chunk checking is working
+ Turn off some tests for big-endian architectures since zstd
isn't deterministic on them
+ Add zck_gen_zdict binary to generate optimal zdict for a zchunk file
+ Add functions to API to simplify extracting a single chunk
+ Change default zstd compression to 9 for a 6x speed increase in
compression speed for a 5% increase in compression size
+ Switch from optional flags to more robust optional elements
+ Sanity check hex hashes passed in as an option

|
zchunk is a compressed file format that splits the file into independent
|
|
chunks. This allows you to only download the differences when downloading a
|
|
new version of the file, and also makes zchunk files efficient over rsync.
|
|
zchunk files are protected with strong checksums to verify that the file you
|
|
downloaded is in fact the file you wanted.
