This happens to speed up the decoder benchmarks by 50% on my computer (GOARCH=amd64 GOOS=linux), but I don't have a good intuition as to why. For example, just adding an unused [4096]byte field to the decoder struct doesn't significantly change the numbers.

2011-06-08http: fix handling of 0-lengthed http requestsBrad Fitzpatrick
Via Russ Ross' bug report on golang-nuts, it was not possible to send an HTTP request with a zero length body with either a Content-Length (it was stripped) or chunking (it wasn't set). This means Go couldn't upload 0-length objects to Amazon S3. (which aren't as silly as they might sound, as S3 objects can have key/values associated with them, set in the headers) Amazon further doesn't supported chunked uploads. (not Go's problem, but we should be able to let users set an explicit Content-Length, even if it's zero.) To fix the ambiguity of an explicit zero Content-Length and the Request struct's default zero value, users need to explicit set TransferEncoding to []string{"identity"} to force the Request.Write to include a Content-Length: 0. identity is in RFC 2616 but is ignored pretty much everywhere. We don't even then serialize it on the wire, since it's kinda useless, except as an internal sentinel value. The "identity" value is then documented, but most users can ignore that because NewRequest now sets that. And adds more tests. R=golang-dev, rsc CC=golang-dev https://golang.org/cl/4603041
2011-06-08http: change most map[string][]string types to new Values typeBrad Fitzpatrick

2011-06-07runtime: SysMap uses MAP_FIXED if needed on 64-bit LinuxJonathan Mark
This change was adapted from gccgo's libgo/runtime/mem.c at Ian Taylor's suggestion. It fixes all.bash failing with "address space conflict: map() =" on amd64 Linux with kernel version 2.6.32.8-grsec-2.1.14-modsign-xeon-64. With this change, SysMap will use MAP_FIXED to allocate its desired address space, after first calling mincore to check that there is nothing else mapped there.

2011-06-07big.nat: Improved speed of nat-to-string conversionMichael T. Jones
Three optimizations: First, special-case power of two bases that partion a Word(), bases 2, 4, 16, and 256. These can be moved directly from internal Word() storage to the output without multiprecision operations. Next, same approach for the other power-of-two bases, 8, 32, 64, and 128. These don't fill a Word() evenly, so special handling is needed for those cases where input spans the high-bits of one Word and the low bis of the next one. Finally, implement the general case for others bases in 2 <= base <= 256 using superbases, the largest power of base representable in a Word(). For base ten, this is 9 digits and a superbase of 10^9 for 32-bit Words and 19 digits and 10^19 for 64-bit compiles. This way we do just 1/9th or 1/19th of the expensive multiprecision divisions, unpacking superdigits using fast native machine arithmetic. The resulting code runs 7x to 800x the speed of the previous approach, depending on the length of the number to be converted--longer is relatively faster. Also, extended the tests and benchmarks for string to nat (scan()) and nat to string (string()) functions. A further enhancement awaits the next CL to make general cases about 7x faster for long cases. R=gri CC=golang-dev https://golang.org/cl/4595041
