I believe it's necessary to use a buffer size smaller than 64KB because (at least some versions of) Window using a TCP receive window less than 64KB. Currently the client and server use buffer sizes of 16KB and 32KB, respectively (the server uses io.Copy, which defaults to 32KB internally). Since the server has been using 32KB, it should be safe for the client to do so as well.

The assembly is broken: it does `MOVQ g(R12), R14` expecting that R12 contains tls address, but it does not do get_tls(R12) before. This magically works on linux: `MOVQ g(R12), R14` is compiled to `mov %fs:0xfffffffffffffff8,%r14` which does not use R12. But it crashes on windows. Add explicit `get_tls(R12)`.

Prior to this change package "foo" had to be installed in order to check example names in "foo_test" package. However by the time "foo_test" package is checked a parsed "foo" package has been already constructed. Use it to check example names. Also change TestDivergentPackagesExamples test to pass directory of the package to the vet tool as it is the most common way to invoke it. This requires changes to errchk to add support for grabbing source files from a directory.

TestPendingConnsAfterErr only cared that things didn't deadlock, so 5 seconds is a sufficient timer. We don't need 100 milliseconds. I was able to reproduce with a tiny (5 nanosecond) timeout value, instead of 100 milliseconds. In the process of testing with -race and a high -count= value, I noticed several data races and panics (sendings on a closed channel) which are also fixed in this change.

Several minor changes that remove a good chunk of the overhead added to the reflect Name method over the 1.7 cycle, as seen from the non-SSA architectures. In particular, there are ~20 fewer instructions in reflect.name.name on 386, and the method now qualifies for inlining. The simple JSON decoding benchmark on darwin/386: name old time/op new time/op delta CodeDecoder-8 49.2ms ± 0% 48.9ms ± 1% -0.77% (p=0.000 n=10+9) name old speed new speed delta CodeDecoder-8 39.4MB/s ± 0% 39.7MB/s ± 1% +0.77% (p=0.000 n=10+9) On darwin/amd64 the effect is less pronounced: name old time/op new time/op delta CodeDecoder-8 38.9ms ± 0% 38.7ms ± 1% -0.38% (p=0.005 n=10+10) name old speed new speed delta CodeDecoder-8 49.9MB/s ± 0% 50.1MB/s ± 1% +0.38% (p=0.006 n=10+10) Counterintuitively, I get much more useful benchmark data out of my MacBook Pro than a linux workstation with more expensive Intel chips. While the laptop has fewer cores and an active GUI, the single-threaded performance is significantly better (nearly 1.5x decoding throughput) so the differences are more pronounced. For #16117.

Make sure the pointer to the heap copy of an output parameter is kept live throughout the function. The function could panic at any point, and then a defer could recover. Thus, we need the pointer to the heap copy always available so the post-deferreturn code can copy the return value back to the stack. Before this CL, the pointer to the heap copy could be considered dead in certain situations, like code which is reverse dominated by a panic call. Fixes #16095.

Swtich from a sync.RWMutex to atomic.Value for cacheTypeFields. On GOARCH=386, this recovers most of the remaining performance difference from the 1.6 release. Compared with tip on linux/386: name old time/op new time/op delta CodeDecoder-40 92.8ms ± 1% 87.7ms ± 1% -5.50% (p=0.000 n=10+10) name old speed new speed delta CodeDecoder-40 20.9MB/s ± 1% 22.1MB/s ± 1% +5.83% (p=0.000 n=10+10) With more time and care, I believe more of the JSON decoder's work could be shifted so it is done before decoding, and independent of the number of bytes processed. Maybe someone could explore that for Go 1.8. For #16117.

If we are using a remote source (a URL), and the user did not specify the executable file to use, then don't try to use a local source. This was misbehaving because the local symbolizer will not fail if there is any memory map available, but the presence of a memory map does not ensure that the files and symbols are actually available. We still need a pprof testsuite. Fixes #16159.

Previously, a 0 mantissa was special-cased during big.Float parsing, but not during big.Rat parsing. This meant that a value like 0e9999999999 would parse successfully in big.Float.SetString, but would hang in big.Rat.SetString. This discrepancy became an issue in https://golang.org/src/go/constant/value.go?#L250, where the big.Float would report an exponent of 0, so big.Rat.SetString would be used and would subsequently hang. A Go Playground example of this is https://play.golang.org/p/3fy28eUJuF The solution is to special-case a zero mantissa during big.Rat parsing as well, so that neither big.Rat nor big.Float will hang when parsing a value with 0 mantissa but a large exponent.
