      This change uses runtime.support_bmi2 as an additional condition
to examine the usability of AVX2 version algorithm, fixes
the crash on the platfrom which supports AVX2 but not support BMI2.

      crypto: detect BMI usability on AMD64 for sha1 and sha256 · a2b615d5
      Lion Yang authored 
      The existing implementations on AMD64 only detects AVX2 usability,
when they also contains BMI (bit-manipulation instructions).
These instructions crash the running program as 'unknown instructions'
on the architecture, e.g. i3-4000M, which supports AVX2 but not
support BMI.

This change added the detections for BMI1 and BMI2 to AMD64 runtime with
two flags as the result, `support_bmi1` and `support_bmi2`,
in runtime/runtime2.go. It also completed the condition to run AVX2 version
in packages crypto/sha1 and crypto/sha256.

Fixes #18512

      .gitignore: fix attempt at rooted paths · f5608c20
      Russ Cox authored 
      When I wrote the lines

	bin/
	pkg/

I was trying to match just the top-level bin and pkg directories, and I put the
final slash in because 'git help gitignore' says:

       o   If the pattern does not contain a slash /, Git treats it as a shell
           glob pattern and checks for a match against the pathname relative
           to the location of the .gitignore file (relative to the toplevel of
           the work tree if not from a .gitignore file).

       o   Otherwise, Git treats the pattern as a shell glob suitable for
           consumption by fnmatch(3) with the FNM_PATHNAME flag: wildcards in
           the pattern will not match a / in the pathname. For example,
           "Documentation/*.html" matches "Documentation/git.html" but not
           "Documentation/ppc/ppc.html" or
           "tools/perf/Documentation/perf.html".

Putting a trailing slash was my way of opting in to the "rooted path" semantics
without looking different from the surrounding rooted paths like "src/go/build/zcgo.go".

But HA HA GIT FOOLED YOU! above those two bullets the docs say:

       o   If the pattern ends with a slash, it is removed for the purpose of
           the following description, ...

Change all the patterns to use a leading slash for "rooted" behavior.

This bit me earlier today because I had a perfectly reasonable source
code directory go/src/cmd/go/testdata/src/empty/pkg that was
not added by 'git add empty'.

      cmd/pprof: Re-enable weblist and disasm · 8887be46
      Raul Silvera authored 
      Previous changes started using the full filename for object files
on graph nodes, instead of just the file basename. The basename
was still being used when selecting mappings to disassemble for
weblist and disasm commands, causing a mismatch.

This fixes #18385. It was already fixed on the upstream pprof.

      net/http: restore Transport's Request.Body byte sniff in limited cases · 6e36811c
      Brad Fitzpatrick authored 
      In Go 1.8, we'd removed the Transport's Request.Body
one-byte-Read-sniffing to disambiguate between non-nil Request.Body
with a ContentLength of 0 or -1. Previously, we tried to see whether a
ContentLength of 0 meant actually zero, or just an unset by reading a
single byte of the Request.Body and then stitching any read byte back
together with the original Request.Body.

That historically has caused many problems due to either data races,
blocking forever (#17480), or losing bytes (#17071). Thus, we removed
it in both HTTP/1 and HTTP/2 in Go 1.8. Unfortunately, during the Go
1.8 beta, we've found that a few people have gotten bitten by the
behavior change on requests with methods typically not containing
request bodies (e.g. GET, HEAD, DELETE). The most popular example is
the aws-go SDK, which always set http.Request.Body to a non-nil value,
even on such request methods. That was causing Go 1.8 to send such
requests with Transfer-Encoding chunked bodies, with zero bytes,
confusing popular servers (including but limited to AWS).

This CL partially reverts the no-byte-sniffing behavior and restores
it only for GET/HEAD/DELETE/etc requests, and only when there's no
Transfer-Encoding set, and the Content-Length is 0 or -1.

Updates #18257 (aws-go) bug
And also private bug reports about non-AWS issues.

Updates #18407 also, but haven't yet audited things enough to declare
it fixed.

      runtime: skip floating point hardware check on Android · f419b563
      Elias Naur authored 
      CL 33652 removed the fake auxv for Android, and replaced it with
a /proc/self/auxv fallback. When /proc/self/auxv is unreadable,
however, hardware capabilities detection won't work and the runtime
will mistakenly think that floating point hardware is unavailable.

Fix this by always assuming floating point hardware on Android.

Manually tested on a Nexus 5 running Android 6.0.1. I suspect the
android/arm builder has a readable /proc/self/auxv and therefore
does not trigger the failure mode.
