No backwards incompatible changes here for most usage scenarios, but look carefully on notes below.
- Timers in metrics marked as deprecated.
time_api_mean,time_client_mean,time_api_max,time_client_maxnow return 0. This was made because timer's implementation usedTimerfromgo-metricslibrary that does not suit very well for Centrifugo needs - so values were mostly useless in practice. So we decided to get rid of them for now to not confuse our users. - New
nodeAPI method to get information from single node. That information will contain counters without aggregation over minute interval (whatstatsmethod does by default). So it can be useful if your metric aggregation system can deal with non-aggregated counters over time period itself. Also note that to use this method you should send API request to each Centrifugo node separately - as this method returns current raw statistics about one node. See issue for motivation description. - Centrifugo now handles SIGTERM in addition to SIGINT and makes
shutdownwhen this signal received. During shutdown Centrifugo returns 503 status code on requests to handlers and closes client connections so clients will reconnect. If shutdown finished without errors in 10 seconds interval then Centrifugo exits with status code 0 (instead of 130 before, this fixes behaviour behindsystemdafter SIGTERM received). - Maximum limit in bytes for client request was added. It can be changed using
client_request_max_sizeconfig option. By default 65536 bytes (64kb). - Packages for 64-bit Debian, Centos and Ubuntu hosted on packagecloud.io. If you are using Debian 7 or 8, Centos 6 or 7, Ubuntu 14.04 or Ubuntu 16.04 - you can find packages for those linux distribution following to packagecloud. Packages will be created every time we release new Centrifugo version.
