* 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

* 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.
