It will also be applied to background replication requests, if the BGR mode is FULL. As request coalescing is currently very primitive, this setting should usually be left diabled, and bgrWindowSize used instead, if appropriate. If you enable this, set it to something large (1M+), or it might have adverse effects. 2021-04-14T11:17:59+00:00 Simon Rettberg 2021-04-13T14:41:26+00:00 urn:sha1:0be00336f97a7ef3590ee803d4ad19e305aa1583 There is a race condition where we process the next request from the same client faster than the OS will schedule the async prefetch job, rendering it a NOOP in the best case (request ranges match) or fetching redundant data from the upstream server (prefetch range is larger than actual request by client). Make prefetching synchronous to prevent this race condition. 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. 2020-07-28T15:49:17+00:00 Simon Rettberg 2020-07-28T15:49:17+00:00 urn:sha1:e4dec3562e6cab27e1a3f40165e4c0d9d0bf05c9 Still needs some cleanup and optimizations, variable naming sucks, comments, etc. 2020-03-20T20:22:18+00:00 Simon Rettberg 2020-03-20T20:22:18+00:00 urn:sha1:894eeb86f872a7f7f5f36bfa8649da3075dd28d6 2020-03-20T11:08:10+00:00 Simon Rettberg 2020-03-20T11:08:10+00:00 urn:sha1:a9f5b836d9fddb3e1851c5b0a77c566b0f267ead 2020-03-13T15:03:29+00:00 Simon Rettberg 2020-03-13T15:03:29+00:00 urn:sha1:290d3478f245bb7d2112bb781286a9fbae42b983 - Now uses linked lists instead of huge array - Does prefetch data on client requests - Can have multiple replication requests in-flight
