Calculating l2 offset in metadata file was broken and overlapping l1. Delete unneeded entries from cow struct. Rename a few more variables. Fix a few possible race conditions. Only upload modified blocks from cluster. Simplify cow_write() function by handling misaligned start/end first. Try to also simplify cow_read() a bit. TODO: Documentation, update the cow merger service. 2024-05-13T16:26:42+00:00 Simon Rettberg 2023-03-29T10:03:54+00:00 urn:sha1:ec0b9b5f72607335ac19d4ea00c24919943b7970 - Use the term "cluster" for a group of dnbd3-blocks instead of also calling them blocks. - Use term "table" instead of "array" for the L1 and L2 tables. - Use term "index" instead of "offset" when addressing those tables - Fix a few logic bugs, use-after-free - Add TODOs for parts that need better comments 2024-05-13T16:26:36+00:00 Michael Scherle 2022-09-13T15:25:33+00:00 urn:sha1:4e6ef06945c74198c918c1711c82c84a83ddb870 2024-05-13T16:26:28+00:00 Michael Scherle 2022-08-16T19:12:36+00:00 urn:sha1:b7910305654d1d93f3bcddabc3de3cc969b0402d 2024-05-13T16:26:13+00:00 Michael Scherle 2022-08-09T18:46:59+00:00 urn:sha1:7fb310c8d3ecbfbac5159a4f0dc577ae1cf6fff5 2024-05-13T16:25:14+00:00 Michael Scherle 2022-02-17T17:58:25+00:00 urn:sha1:d92d1d3faf7cde517d8c3fe914301eb5aa872f62
