- updated go-ctxgroup and goprocess ctxgroup: AddChildGroup was changed to AddChild. Used in two files: - p2p/net/mock/mock_net.go - routing/dht/dht.go - updated context from hg repo to git prev. commit in hg was ad01a6fcc8a19d3a4478c836895ffe883bd2ceab. (context: make parentCancelCtx iterative) represents commit 84f8955a887232b6308d79c68b8db44f64df455c in git repo - updated context to master (b6fdb7d8a4ccefede406f8fe0f017fb58265054c) Aaron Jacobs (2): net/context: Don't accept a context in the DoSomethingSlow example. context: Be clear that users must cancel the result of WithCancel. Andrew Gerrand (1): go.net: use golang.org/x/... import paths Bryan C. Mills (1): net/context: Don't leak goroutines in Done example. Damien Neil (1): context: fix removal of cancelled timer contexts from parent David Symonds (2): context: Fix WithValue example code. net: add import comments. Sameer Ajmani (1): context: fix TestAllocs to account for ints in interfaces
