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. 2023-03-29T10:03:54+00:00 Simon Rettberg 2023-03-29T10:03:54+00:00 urn:sha1:9836f97fa0cbcac9394bd7d1a91671d6521812a9 - 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 2021-03-26T12:44:47+00:00 Simon Rettberg 2021-03-26T12:44:47+00:00 urn:sha1:3a7891e26aec9e5d15d21a78cb317926d96f51e9 Similar logic already exists in the fuse client: Count how many times in a row a server was fastest when measuring RTTs, and lower the switching threshold more the higher the count gets. 2020-10-16T15:15:49+00:00 Manuel Bentele 2020-10-16T15:15:49+00:00 urn:sha1:969496f15e1e0359e26c2c6e995ad4ef82720f86 This change restructures the source code directories, separates shared form non-shared application code and adds CMake dependencies. These dependencies allow the tracking of changes and trigger a rebuild of those build targets where changed files are involved. WARNING: Note that the support of the DNBD3_SERVER_AFL build option is not supported yet. Thus, the option should be never turned on.
