I got following warning after upgrading dep tool: Warning: the following project(s) have [[constraint]] stanzas in Gopkg.toml: ✗ github.com/hashicorp/yamux However, these projects are not direct dependencies of the current project: they are not imported in any .go files, nor are they in the 'required' list in Gopkg.toml. Dep only applies [[constraint]] rules to direct dependencies, so these rules will have no effect. Either import/require packages from these projects so that they become direct dependencies, or convert each [[constraint]] to an [[override]] to enforce rules on these projects, if they happen to be transitive dependencies, So let's convert constraint to override over yamux. In the meanwhile, update the yamux vendor. Full commit list: 4c2fe0d (origin/b-consul-3040) Dont output keepalive error when the session is closed f21aae5 Make sure to drain the timer channel on defer, and a clarifying comment 601ccd8 Make receive window update logic a bit cleaner 02d320c Uses timer pool in sendNoWait, like in waitForSendErr cf433c5 window update unit test for partial read; benchmark large buffer ca8dfd0 improve memory utilization in receive buffer, fix flow control 683f491 Fix race around read and write deadlines in Stream (#52) 40b86b2 Add public session CloseChan method (#44) Note that commit 4c2fe0d might also help kata-containers/agent/issues/231.
