This is an automated follow-up to CL 10120. It was generated with a combination of eg and gofmt -r. No functional changes. Passes toolstash -cmp. Change-Id: I0dc6d146372012b4cce9cc4064066daa6694eee6 Reviewed-on: https://go-review.googlesource.com/10144Reviewed-by:

The previous implementation spawned an extra goroutine to handle rechecking resolv.conf for changes. This change eliminates the extra goroutine, and has rechecking done as part of a lookup. A side effect of this change is that the first lookup after a resolv.conf change will now succeed, whereas previously it would have failed. It also fixes rechecking logic to ignore resolv.conf parsing errors as it should. Fixes #8652 Fixes #10576 Fixes #10649 Fixes #10650 Fixes #10845 Change-Id: I502b587c445fa8eca5207ca4f2c8ec8c339fec7f Reviewed-on: https://go-review.googlesource.com/9991 Run-TryBot: Matthew Dempsky <mdempsky@google.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

This extends cmd/yacc with support for %error { tokens } : message syntax to specify custom error messages to use instead of the default generic ones. This allows merging go.errors into go.y and removing the yaccerrors.go tool. Updates #9968.

All slice types which have elements of kind reflect.Uint8 are marshalled into base64 for compactness. When decoding such data into a custom type based on []byte the decoder checked the slice kind instead of the slice element kind, so no appropriate decoder was found. Fixed by letting the decoder check slice element kind like the encoder. This guarantees that already encoded data can still be successfully decoded. Fixes #8962.

Preallocating them in reflect means that (1) if you say _ = PtrTo(ArrayOf(1000000000, reflect.TypeOf(byte(0)))), you just allocated 1GB of data (2) if you say it again, that's *another* GB of data. The only use of t.zero in the runtime is for map elements. Delay the allocation until the creation of a map with that element type, and share the zeros. The one downside of the shared zero is that it's not garbage collected, but it's also never written, so the OS should be able to handle it fairly efficiently.

According to MSDN RegQueryValueEx page: If the data has the REG_SZ, REG_MULTI_SZ or REG_EXPAND_SZ type, the string may not have been stored with the proper terminating null characters. Therefore, even if the function returns ERROR_SUCCESS, the application should ensure that the string is properly terminated before using it; otherwise, it may overwrite a buffer. (Note that REG_MULTI_SZ strings should have two terminating null characters.)

It's dumb to clear them in initSpan, set them in heapBitsSetType, clear them in heapBitsSweepSpan, set them again in heapBitsSetType, clear them again in heapBitsSweepSpan, and so on. Set them in initSpan and be done with it (until the span is reused for objects of a different size). This avoids an atomic operation in a common case (one-word allocation).

This reduces the depth of the inlining at a particular call site. The inliner introduces many temporary variables, and the compiler can do a better job with fewer. Being verbose in the bodies of these helper functions seems like a reasonable tradeoff: the uses are still just as readable, and they run faster in some important cases.
