This is simply a change of read_chunk() protocol, where a response of read_chunk() becomes list of written bytes along with checksum. All related code including repair is changed as such. This is to pass all tests and not actually supporting partial chunks.

<<"Four score and seven years ago our fathers brought forth on this
|
|
continent a new nation, conceived in liberty, and dedicated to the
|
|
proposition that all men are created equal.
|
|
|
|
Now we are engaged in a great civil war, testing whether that nation, or any
|
|
nation so conceived and so dedicated, can long endure. We are met on a great
|
|
battlefield of that war. We have come to dedicate a portion of that field, as a
|
|
final resting place for those who here gave their lives that that nation
|
|
might live. It is altogether fitting and proper that we should do this.
|
|
|
|
But, in a larger sense, we can not dedicate, we can not consecrate, we can not
|
|
hallow this ground. The brave men, living and dead, who struggled here, have
|
|
consecrated it, far above our poor power to add or detract. The world will
|
|
little note, nor long remember what we say here, but it can never forget what
|
|
they did here. It is for us the living, rather, to be dedicated here to the
|
|
unfinished work which they who fought here have thus far so nobly advanced. It
|
|
is rather for us to be here dedicated to the great task remaining before us—
|
|
that from these honored dead we take increased devotion to that cause for which
|
|
they gave the last full measure of devotion— that we here highly resolve that
|
|
these dead shall not have died in vain— that this nation, under God, shall have
|
|
a new birth of freedom— and that government of the people, by the people, for
|
|
the people, shall not perish from the earth.">>.
