Re: [go-nuts] where in gc compiler does converting from syntax.TypeDecl to reflect.Type happen?

I can give you a little bit of a start: I looked at the runtime recently, and its representation is here . It doesn't tell you how the creation/translation happens, but it tells you how the

[go-nuts] where in gc compiler does converting from syntax.TypeDecl to reflect.Type happen?

I wrote some code to convert (go/types) types.Type to reflect.Type, but I kept thinking, "this has to be done somewhere already in the runtime or compiler libraries...", doesn't it? [ I know gc doesn't use go/types, but assume I'm asking about the equivalent (say

Hi Sina, here’s a general code review. gradboostreg/tree, stat, sample have no tests. These sub-packages may be better in package gradboostreg since they seem straightforward and contained to this library. Keeping those things in sub-packages doesn’t seem to add much value over just having

Thanks! I'm not willing close the connection on every request -- that's too painful. I don't need an _exact_ count, but I want to be confident that my counts are really close. Serializing the headers and adding the size of the body is the closest that I've come up with to do accurate

[go-nuts] Re: Async process state snapshotting in Golang

My main goal is to avoid complex granular locking inside the data structure since writes are very common in the map (whether its adding items or modifying the actual item). My idea was to implement MarshalJSON for my map and then while creating the JSON I'd be holding locks at the appropriate

Re: [go-nuts] Why []Interface{} indexing failing at if statement

Actually, Jan's way is probably the best... as if you wrongfully type convert the wrong type, it'll panic (you'll need to know for sure that arr in this instance will always be a boolean). With Jan's way, you're just making a comparison of value... which will work regardless of the type. On

Hi Quentin, here’s a code review. Since type ability is not exported, why not embed sync.Mutex? What does o stand for? I’d say that comments like “// newAbility creates a new ability” are unnecessary. The identifiers are documentation. There are many unnecessary comments. For read-only

[go-nuts] Re: Async process state snapshotting in Golang

Can you describe your performance needs in more detail? I missed the need for the struct values in the copy (obviously needed to encode to JSON). Going back to locks for a moment, my thought now is that a sync.RWMutex on this map would have an RLock taken by every struct read/write and then

[go-nuts] Re: Async process state snapshotting in Golang

Hi, Thanks for all the input. Unfortunately, as Tamás and Jake pointed out, I can't simply grab a copy of the map that has the same pointers since I'll need to be locking the structure everytime I'm copying it. So that means Matt's idea wouldn't really work for my use-case I was really hoping
