The spec defines precise numeric constants which do not overflow. Consequently, +/-Inf and NaN values were excluded. The case was not clear for -0.0 but they are mostly of interest to determine the sign of infinities which don't exist. That said, the conversion rules explicitly say that T(x) (for a numeric x and floating-point type T) is the value after rounding per IEEE-754. The result is constant if x is constant. Rounding per IEEE-754 can produce a -0.0 which we cannot represent as a constant. Thus, the spec is inconsistent. Attempt to fix the inconsistency by adjusting the rounding rule rather than letting -0.0 into the language. For more details, see the issue below. Open to discussion. Fixes #12576.

For printing, the format verb '%X' results in a capitalized hex-representation of the formatted value. Conversely, using '%X' in a Scanf function should scan a hex-representation into the given interface{}. The existing implementation however only supports '%X' for scanning hex values into integers; strings or byte slices remain empty. On the other hand, lower-case '%x' supports strings and byte slices just fine. This is merely an oversight, which this commit fixes. (Additional tests also included.)

This is the start of wiring up the HTTP/2 Transport. It is still disabled in this commit. This change does two main things: 1) Transport.RegisterProtocol now permits registering "http" or "https" (they previously paniced), and the semantics of the registered RoundTripper have been extended to say that the new sentinel error value (ErrSkipAltProtocol, added in this CL) means that the Transport's RoundTrip method proceeds as if the alternate protocol had not been registered. This gives us a place to register an alternate "https" RoundTripper which gets first dibs on using HTTP/2 if there's already a cached connection. 2) adds Transport.TLSNextProto, a map keyed by TLS NPN/ALPN protocol strings, similar in feel to the existing Server.TLSNextProto map. This map is the glue between the HTTP/1 and HTTP/2 clients, since we don't know which protocol we're going to speak (and thus which Transport type to use) until we've already made the TCP connection.

Currently gcResetGState is called by func gcscan_m for concurrent GC and directly by func gc for STW GC. Simplify this by consolidating these two calls in to one call by func gc above where it splits for concurrent and STW GC. As a consequence, gcResetGState and gcResetMarkState are always called together, so the next commit will consolidate these.

The flate library guarantees that the Reader will never read more bytes than is necessary. This way, the underlying io.Reader will be left exactly after the last byte of the DEFLATE stream. Formats like gzip depend on this behavior being true. As such, inflate conservatively reads the minimum symbol length in huffSym leading to many individual calls to moreBits. However, if we take advantage of the fact that every block *must* end with the EOB symbol, we can choose to read the length of the EOB symbol. Since the EOB symbol is also the most rare symbol (occuring exactly once) in a block, we can hypothesize that it is almost as long as the max symbol length, allowing huffSym to ask for more bits at the start of every loop. This increases the probabilty that the Huffman code is decoded on the first iteration of the outer for-loop. benchmark old MB/s new MB/s speedup BenchmarkDecodeDigitsSpeed1e4-4 51.05 54.31 1.06x BenchmarkDecodeDigitsSpeed1e5-4 58.86 62.24 1.06x BenchmarkDecodeDigitsSpeed1e6-4 59.63 63.13 1.06x BenchmarkDecodeDigitsDefault1e4-4 51.94 54.61 1.05x BenchmarkDecodeDigitsDefault1e5-4 63.70 69.13 1.09x BenchmarkDecodeDigitsDefault1e6-4 66.08 71.43 1.08x BenchmarkDecodeDigitsCompress1e4-4 52.25 54.56 1.04x BenchmarkDecodeDigitsCompress1e5-4 63.34 68.30 1.08x BenchmarkDecodeDigitsCompress1e6-4 66.84 70.64 1.06x BenchmarkDecodeTwainSpeed1e4-4 50.74 53.40 1.05x BenchmarkDecodeTwainSpeed1e5-4 60.77 67.03 1.10x BenchmarkDecodeTwainSpeed1e6-4 62.08 69.78 1.12x BenchmarkDecodeTwainDefault1e4-4 53.45 56.40 1.06x BenchmarkDecodeTwainDefault1e5-4 73.54 79.05 1.07x BenchmarkDecodeTwainDefault1e6-4 77.68 83.65 1.08x BenchmarkDecodeTwainCompress1e4-4 53.21 56.15 1.06x BenchmarkDecodeTwainCompress1e5-4 73.82 77.76 1.05x BenchmarkDecodeTwainCompress1e6-4 79.23 83.30 1.05x Change-Id: Ie194925c827988a380b8c2fdd13b13c4faa5d397 Reviewed-on: https://go-review.googlesource.com/15651Reviewed-by:

Go cannot allow lazy PLT resolution when calling between Go functions because the lazy resolution can use more stack than is available. Lazy resolution is disabled by passing -z now to the system linker, but unfortunately was only passed when linking to a Go shared library. That sounds fine, but the shared library containing the runtime is not linked to any other Go shared library but calls main.init and main.main via a PLT, and before this fix this did use lazy resolution. (For some reason this never caused a problem on intel, but it breaks on ppc64le). Fortunately the fix is very simple: always pass -z now to the system linker when dynamically linking Go.

Current http client doesn't support Expect: 100-continue request header(RFC2616-8/RFC7231-5.1.1). So even if the client have the header, the head of the request body is consumed prematurely. Those are my intentions to avoid premature consuming body in this change. - If http.Request header contains body and Expect: 100-continue header, it blocks sending body until it gets the first response. - If the first status code to the request were 100, the request starts sending body. Otherwise, sending body will be cancelled. - Tranport.ExpectContinueTimeout specifies the amount of the time to wait for the first response.
