When GTS is running in a container runtime which has configured CPU or memory limits or under an init system that uses cgroups to impose CPU and memory limits the values the Go runtime sees for GOMAXPROCS and GOMEMLIMIT are still based on the host resources, not the cgroup. At least for the throttling middlewares which use GOMAXPROCS to configure their queue size, this can result in GTS running with values too big compared to the resources that will actuall be available to it. This introduces 2 dependencies which can pick up resource contraints from the current cgroup and tune the Go runtime accordingly. This should result in the different queues being appropriately sized and in general more predictable performance. These dependencies are a no-op on non-Linux systems or if running in a cgroup that doesn't set a limit on CPU or memory. The automatic tuning of GOMEMLIMIT can be disabled by either explicitly setting GOMEMLIMIT yourself or by setting AUTOMEMLIMIT=off. The automatic tuning of GOMAXPROCS can similarly be counteracted by setting GOMAXPROCS yourself. |

dbus
dbus is a simple library that implements native Go client bindings for the D-Bus message bus system.
Features
- Complete native implementation of the D-Bus message protocol
- Go-like API (channels for signals / asynchronous method calls, Goroutine-safe connections)
- Subpackages that help with the introspection / property interfaces
Installation
This packages requires Go 1.7. If you installed it and set up your GOPATH, just run:
go get github.com/godbus/dbus
If you want to use the subpackages, you can install them the same way.
Usage
The complete package documentation and some simple examples are available at godoc.org. Also, the _examples directory gives a short overview over the basic usage.
Projects using godbus
- notify provides desktop notifications over dbus into a library.
- go-bluetooth provides a bluetooth client over bluez dbus API.
- playerbm a bookmark utility for media players.
- iwd go bindings for the internet wireless daemon "iwd".
Please note that the API is considered unstable for now and may change without further notice.
