+The State of Go
+Where we are in June 2014
+
+Andrew Gerrand
+
+* Yesterday
+
+
+* Initial reception
+
+Looking back on the first months.
+
+
+* Complaints
+
+The complaints started right away…

+
+The first HN thread about Go was mostly an argument about braces and indentation.
+
+
+* Historic moments
+
+The first public language change (Dec 10, 2009):

+
+* Go 1.3
+
+Released last Wednesday, 18 June 2014.
+
+Highlights:
+
+- Native Client support (amd64, 386)
+- DragonFly BSD, Plan 9, and Solaris support
+- Improved performance (GC, contiguous stacks, race detector, regexp)
+- Faster incremental builds (linker overhaul)
+- Precise GC of stacks
+- Static analysis in godoc
+
+
+* Tomorrow
+
+
+* Upcoming conferences

+
+
+* Go 1.4
+
+Due December 1st, 2014.
+
+What might be in it? (Speculative list follows.)
+
+
+* New language features
+
+Nope.
+
+
+* Canonical import paths
+
+A means for a repository to specify its canonical import path.
+
+Goal: stop people from checking out repos from the wrong path.
+
+Applications:
+
+- Stable vanity import paths.
+
+ "camlistore.org" -> "camlistore.googlesource.com/camlistore"
+
+- Make GitHub's fork model less painful.
+
+(Proposal forthcoming.)
+
+
+* Internal packages
+
+Current proposal:
+
+"An import of a path containing the element “internal” is disallowed if the importing code is outside the tree rooted at the parent of the “internal” directory."
+
+- Code in `/a/b/c/internal/d/e/f` can be imported only by code in the directory tree rooted at `/a/b/c`.
+- `$GOROOT/src/pkg/internal/xxx` can be imported only by other code in the standard library (`$GOROOT/src/`).
+
+And, later:
+
+- `$GOPATH/src/mypkg/internal/foo` can be imported only by code in `$GOPATH/src/mypkg`.
+
+.link http://golang.org/s/go14internal
+
+
+* src/pkg → src
+
+Move the standard library from `$GOROOT/src/pkg` to `$GOROOT/src`.
+
+Basically makes `$GOROOT` work just like `$GOPATH`.
+
+(Not a big deal for most, but a nice clean up for the core.)
+
+.link http://golang.org/s/go14nopkg
+
+
+* File system access throttling
+
+Throttling of access to the file system at the `os` package level.
+
+Goal:
+
+- Launch a million goroutines that do file system stuff.
+- Don't launch a million operating system threads to block on the syscalls.
+
+Make it work just as nicely as it does with the network.
+
+(Proposal forthcoming.)
+
+
+* "go generate"
+
+A convenience for generating Go source code. Example uses:
+
+- yacc: generating .go files from yacc grammar (.y) files
+- protobufs: generating .pb.go files from protocol buffer definition (.proto) files
+- HTML: embedding .html files into Go source code
+- Other ideas abound…
+
+Proposed mechanism:
+
+Add generator directive in Go source files:
+
+ //go:generate yacc -o gopher.go gopher.y
+
+Use the Go tool to execute the directives:
+
+ % go generate [packagepath]
+
+(Proposal forthcoming.)
+
+
+* More tool chain work
+
+- `cmd/go` support for `gccgo`
+- `cmd/go` support for embedded data files
+- Race detector improvements
+
+The transition from C to Go continues:
+
+- Linker rewritten in Go (`cmd/link`)
+- Assembler rewritten in Go (`cmd/asm`)
+- Possibly: `cmd/gc` translated to Go
+
+
+* Better GC and malloc
+
+- The existing allocator is based on TCMalloc (designed for C/C++). It can be re-designed to better suit Go.
+- Lighter representation and colocation of GC metadata.
+- Various strategies for reducing GC pause time (concurrent sweep, etc).
+
+Rough estimate: 10-20% overall speedup, 20-50% GC pause reduction, 5-10% RSS reduction.
+
+Details:
+
+.link http://golang.org/s/go14mallocgc
+
+* Other runtime changes
+
+Concurrency improvements:
+
+- Lock-free fast path for non-blocking receive from empty channel.
+- Rewrite select to hold only one channel lock at a time.
+
+C to Go:
+
+- G-stack runtime converted to Go.
+
+
+* Package changes
+
+- Easier structuring features in `text/template`
+- Bring `reflect.Value` back to 3 words
+- Fix embedded field visibility (`reflect`)
+- Safe version of `encoding/gob`
+- Unicode 7 support
+
+
+* Ports
+
+- Native Client `arm`
+- PowerPC 64
+- ARM64
+
+
+* Go support for Android
+
+Go support for the NDK. (Like C/C++ today, but better!)
+
+Goal: enough support for writing games.
+
+Based on the work of Elias Naur and others in the community.
