* [Feature] Improve address rotation algorithmVsevolod Stakhov2024-12-071-7/+49
| | | | | | | | We apply the following algorithm: 1) Get the current element and it's AF 2) If the next element has the same AF, then we just move to the next element 3) If the next element has different AF, then we should find the next element with the same AF 4) If we cannot find such element, then we return the next element (switching AF)

|
* [CritFix] Fix upstreams name resolution when there is also a portVsevolod Stakhov2022-02-071-3/+29
| | | | | | | | This fix is intended to address the case when Rspamd queries for a hostname with a port part when re-resolving upstreams addresses via the upstreams module. Found by: @slavkoja Confirmed by: @moisseev
* [Minor] Remove sequential algorithm as it is not actually a rotation algVsevolod Stakhov2022-01-181-4/+0
| | | | | | | Sequential rotation was used just to rotate all upstreams in the loop (e.g. when you need to do some action for all upstreams). Allowing to specify it as a user defined algorithm was a mistake as it breaks upstreams API expectations. See #4043
* [Minor] Allow to get a port for a specific upstreamVsevolod Stakhov2021-11-071-0/+9

* [Fix] Fix consistent hashing when upstreams are marked inactiveVsevolod Stakhov2019-10-301-37/+91
| | | | | | | The idea is to rehash the value when we found that the current upstream is dead and apply consistent hashing algorithm multiple times. This is limited by number of attempts (we try 10 times before giving up). Also cleanup locking stuff.

* [Fix] Core: Fix address rotation bugVsevolod Stakhov2019-02-181-1/+7
| | | | | | | | | | | | | | | | | | | | | | Previously, upstream.get_addr function returned the new address of the upstream. Unfortunately, it was used for printing addresses. It caused the following situation: let's imagine we have A1 and A2 where A1 was initially selected. So the connection was performed to A1: Current addr Selected addr Connect+---------+ A2+------>A1 A1 | +-+Print failure<---+ A1+------>A2 A2 | +----+ +->Mark failure+-------->+ A2 | +----+ But the failure OP as well as log message told about `A2` where the real problem happened with `A1`. This commit adds distinguishing between getting the next and the current address of the upstream resolving this issue.
