Re: [go-nuts] access runtime implemented functions

The short answer: you can't, and it is a feature. The runtime "injects" certain functions into certain packages in order to build a bridge between the (internal) runtime and the "package world" accessible to programmers. Thus, they are only accessible in that package specific package (time). The

Not to throw a spanner into the works, but we have a similar problem in my work environment of needing a scheduler to schedule distributed jobs, one problem of writing a *nice* one for a given language is that you end up being pigeon holed into one solution. We've been looking at using drmaa as

hmm... I really don't want people to have to build Mage, since mage is a build tool. Would it be horrible to just run go env GOROOT and use that to set GOROOT in the environs for the command that runs go build? On Sunday, October 15, 2017 at 5:36:43 PM UTC-4, Dave Cheney wrote: > > My guess

[go-nuts] Cross compiled binary caches goroot?

My guess is that GOROOT is not set in the target environment so the value eventually collapses back on the GOROOT compiled into mage from the value compiled into the toolchain that built mage. gb has the same problem, I didn’t want to encourage people to set GOROOT, but if they don’t, there

Not a spanner at all. I think the Task Execution Schemas (TES) [1], which Funnel is based on, is a reinvention of DRMAA using technologies such as HTTP, REST, JSON, Protobuf. It's a pretty simple API and message type (Task) for create, get, list, cancel. But, admittedly, I don't know enough

My feeling is that a variable paired with a sync.Cond might be the right choice if you are broadcasting a single value change. I can't think of an readily available lib / language feature to support broadcasting multiple value change though. On Monday, 16 October 2017 06:36:36 UTC+10, st ov
