Re: [go-nuts] Add comparisons to all types

How would this apply to inlined functions? supporting equality would
essentially force the compiler to keep a the function in the output binary even
if it's inlined everywhere it's called, just for comparisons. It would also
complicate
Here's another example:
type worker struct { ... }
func shutDown() { ... }
func (w *worker) run(orders <-chan func()) {
for f := range orders {
if(f == shutDown) {
log.Printf("got a shutdown command")
w.Cleanup()
}
f()
}
}
currently, Go programs run on a single computer. What if a Go runtime was built
that ran Go programs across many computers? Or, put another way, what if a
system architecture emerged where the instruction access time varied so
drastically across CPU cores that it made sense to duplicate functions across
cores' fast memory regions, so that the receive operation in the above example
actually received a duplicate copy of a function? I will admit that closures
with mutable data segments already complicate such an optimization, but
function equality would thwart such an optimization altogether.

Re: [go-nuts] Re: appengine golang logs
Sankar, Have you tried using the Flexible environment? Flex provides a more "conventional" environment for your programs. There are some tradeoffs compared with App Engine Standard, but it should be easier to stay portable.

Re: [go-nuts] sanitize filename from post form upload
To sanitize a file path you can use https://golang.org/pkg/path/#Clean , but you probably want to use https://golang.org/pkg/path/#Base . The reason is that depending on the browser/client, you may get a path containing slashes, or you may get just the base filename. So it's better to just extract the base filename and treat everyone the same.

Re: [go-nuts] Re: correct/working 9p2000 library in Go?
I'm the author of this one[1], and I hate to contribute to the OP's initial complaint, but it is not complete. I plan to make it as easy to use as net/http, but I can only find so much time to work on it. I've also fixed a number of bugs that arose from my misunderstanding of the protocol, so it would only be compliant by luck right now. I did use it to write a toy server[2], so it's functional, but definitely a moving target.

[go-nuts] [ANN] styx - create 9P2000 file servers
https://aqwari.net/net/styx It has taken quite a few more weekends than I expected, but I've produced the styx package and its subpackages as a way to write 9P file servers, with https://github.com/droyo/jsonfs serving as a demo. I have tried to take some inspiration from the standard library's net/http package, without hiding the statefulness of the 9P2000 protocol. It is still early days; I am still filling in gaps in the tests and documentation, but this project has been a lot of fun for me and I wanted to share. Any feedback is appreciated. - David -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
