2023-05-05reverseproxy: Optimize base case for least_conn and random_choose policies ↵Francis Lavoie
(#5487) When only a single request has the least amount of requests, there's no need to compute a random number, because the modulo of 1 will always be 0 anyways.

2022-12-05reverseproxy: Improve hostByHashing distribution (#5229)Alban Lecocq
* If upstreams are all using same host but with different ports ie: foobar:4001 foobar:4002 foobar:4003 ... Because fnv-1a has not a good enough avalanche effect Then the hostByHashing result is not well balanced over all upstreams As last byte FNV input tend to affect few bits, the idea is to change the concatenation order between the key and the upstream strings So the upstream last byte have more impact on hash diffusion
2022-11-14reverseproxy: Mask the WS close message when we're the client (#5199)Francis Lavoie
* reverseproxy: Mask the WS close message when we're the client * weakrand * Bump golangci-lint version so path ignores work on Windows * gofmt * ugh, gofmt everything, I guess
2022-07-28Ignore linter warningsMatthew Holt
Use of non-cryptographic random numbers in the load balancing is intentional.
2022-04-27reverseproxy: Improve hashing LB policies with HRW (#4724)Matt Holt
* reverseproxy: Improve hashing LB policies with HRW Previously, if a list of upstreams changed, hash-based LB policies would be greatly affected because the hash relied on the position of upstreams in the pool. Highest Random Weight or "rendezvous" hashing is apparently robust to pool changes. It runs in O(n) instead of O(log n), but n is very small usually. * Fix bug and update tests
2021-04-29reverseproxy: fix hash selection policy (#4137)Simão Gomes Viana

2020-01-18reverse_proxy: CB docs; rename type -> factor (#2986)Mohammed Al Sahaf
* v2: add documentation for circuit breaker config and "random selection" load balancing policy * v2: rename circuit breaker config inline key from `type` to `breaker` to avoid json key clash between the `circuit_breaker` type and the `type` field of the generic circuit breaker Config struct used by circuit breaking implementations * v2: restore the circuit breaker inline key to `type` and rename the name circuit breaker config field from `Type` to `Factor`
2019-12-10v2: Module documentation; refactor LoadModule(); new caddy struct tags (#2924)Matt Holt
This commit goes a long way toward making automated documentation of Caddy config and Caddy modules possible. It's a broad, sweeping change, but mostly internal. It allows us to automatically generate docs for all Caddy modules (including future third-party ones) and make them viewable on a web page; it also doubles as godoc comments. As such, this commit makes significant progress in migrating the docs from our temporary wiki page toward our new website which is still under construction. With this change, all host modules will use ctx.LoadModule() and pass in both the struct pointer and the field name as a string. This allows the reflect package to read the struct tag from that field so that it can get the necessary information like the module namespace and the inline key. This has the nice side-effect of unifying the code and documentation. It also simplifies module loading, and handles several variations on field types for raw module fields (i.e. variations on json.RawMessage, such as arrays and maps). I also renamed ModuleInfo.Name -> ModuleInfo.ID, to make it clear that the ID is the "full name" which includes both the module namespace and the name. This clarity is helpful when describing module hierarchy. As of this change, Caddy modules are no longer an experimental design. I think the architecture is good enough to go forward.
