Russ Cox	5e4e3d8e44	net: avoid Shutdown during Close ... Once we've evicted all the blocked I/O, the ref count should go to zero quickly, so it should be safe to postpone the close(2) until then. Fixes #1898. Fixes #2116. Fixes #2122. R=golang-dev, mikioh.mikioh, bradfitz, fullung, iant CC=golang-dev https://golang.org/cl/5649076	2012-02-14 00:40:37 -05:00
Brad Fitzpatrick	4152b43457	os: delete Exec, NewFile takes uintptr, rename ShellExpand, doc fixes ... Delete O_NDELAY, O_NONBLOCK, O_NOCTTY, O_ASYNC. Clean up some docs. Rename ShellExpand -> ExpandEnv. Make NewFile take a uintptr; change File.Fd to return one. (for API compatibility between Unix and Windows) Fixes #2947 R=golang-dev, r CC=golang-dev https://golang.org/cl/5655045	2012-02-10 14:16:15 +11:00

Brad Fitzpatrick	b71883e9b0	net: change SetTimeout to SetDeadline ... Previously, a timeout (in int64 nanoseconds) applied to a granularity even smaller than one operation: a 100 byte read with a 1 second timeout could take 100 seconds, if the bytes all arrived on the network 1 second apart. This was confusing. Rather than making the timeout granularity be per-Read/Write, this CL makes callers set an absolute deadline (in time.Time) after which operations will fail. This makes it possible to set deadlines at higher levels, without knowing exactly how many read/write operations will happen in e.g. reading an HTTP request.

Russ Cox	c017a8299f	syscall: use error ... - syscall (not os) now defines the Errno type. - the low-level assembly functions Syscall, Syscall6, and so on return Errno, not uintptr - syscall wrappers all return error, not uintptr.
