I mostly concur - Go really needs TLS - simplifies this sort of thing. You can look at many “complex” Java based server systems and the method calls are far simpler in the common case (especially when using a framework that leverages TLS).
I think a key issue is that most ‘requests’ are not long-enough lived for the cancellation context to be warranted - otherwise the site would be too slow anyway. You see this need in “background jobs” - and still, these jobs are usually per server/application, not per user or per request. Systems that perform time consuming data analysis jobs on behalf of a user are a different case, and they clearly need a way to stop their processing. And yes the ‘not type safe api’ for values is a problem. If Go really wants to promote the context as ubiquitous it should have built-in language support to address these issues (type safety, no need for TLS, required at Go routine creation site, etc.). > On Jan 13, 2019, at 6:35 PM, Space A. <reexist...@gmail.com> wrote: > > I just leave it here > > Context should go away for Go 2 > <https://faiface.github.io/post/context-should-go-away-go2/> > > > > воскресенье, 13 января 2019 г., 22:21:50 UTC+3 пользователь Tamás Gulácsi > написал: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA256 > > There should be a "global" or parent Context, which is canceled when the > server is going to shut down (e.g. with signal.Notify), and each handler > should create a child context with a proper timeout. > > And it should watch the request's Context, too, as that's what will be > canceled when the client disconnects. github.com/LK4D4/joincontext > <http://github.com/LK4D4/joincontext> may help with tis. > > But if you use the request's Context only with a propert timeout, that's > already better than doing nothing. > > Tamás > > > ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ > On 2019.
