Harshavardhana	9add048f3c	erasure: Add erasure encode/decode unit tests. (#1911 ) Fixes #1819	2016-06-26 03:32:49 -07:00
Krishna Srinivas	cb1200a66d	XL/erasure-read: read disks in parallel. (#1975 ) On read failure, fallback to reads from other disks also happen in parallel.	2016-06-24 18:02:10 -07:00
Harshavardhana	e8990e42c2	XL: Make allocations simpler avoid redundant allocs. (#1961 ) - Reduce 10MiB buffers for loopy calls to use 128KiB. - start using 128KiB buffer where needed.	2016-06-24 02:06:23 -07:00
Harshavardhana	9b82e64a11	XL/erasure-read: Avoid memory copy, write to writer directly all the dataBlocks.	2016-06-23 02:06:57 +05:30
Krishna Srinivas	d4bea5fbf8	XL/erasure-read: Add Comments and enable bitrot detection.	2016-06-23 00:34:47 +05:30
Krishna Srinivas	17efaaa902	XL/erasure-read: Support parallel reads from disks.	2016-06-23 00:34:47 +05:30
Bala FA	7d757033f2	erasure-readfile: Use chunk size to read from each disk for a block. (#1949 ) A block of data is split into data chunk and each data chunk is written to each disk. Previously block size was used to read data chunk which returns corrupted data. This patch fixes the issue by reading chunk sized data from each disk and assembles a block. Fixes #1939	2016-06-20 21:40:10 -07:00
Bala FA	1ea1dba528	erasure-readfile: write to given Writer than returning buffer. (#1910 ) Fixes #1889	2016-06-19 13:35:26 -07:00

Harshavardhana	feb337098d	XL: bring in new storage API. (#1780 ) Fixes #1771	2016-05-28 16:12:51 -07:00
Harshavardhana	27cc8a6529	erasure: read only dataBlocks if we have enough. (#1776 ) Reconstruct with parity blocks if we don't have enough data blocks.	2016-05-28 15:15:53 -07:00
Harshavardhana	d65101a8c8	XL: Implement strided erasure distribution. (#1772 ) Strided erasure distribution uses a new randomized block distribution for each Put operation. This information is captured inside `xl.json` for subsequent Get operations.	2016-05-28 15:15:53 -07:00
Harshavardhana	553fdb9211	XL: Bring in support for object versions written during writeQuorum. (#1762 ) Erasure is initialized as needed depending on the quorum and onlineDisks. This way we can manage the quorum at the object layer.	2016-05-28 15:15:53 -07:00
