crypto/x509: update __MAC_OS_X_VERSION_MAX_ALLOWED on Mac · dd1e7b3b

Brad Fitzpatrick authored Nov 02, 2016

Reportedly, -mmacosx-version-min=10.6 -D__MAC_OS_X_VERSION_MAX_ALLOWED=1060
is problematic.

It means min 10.6 and max 10.6, thus exactly 10.6. But we only support
10.8+.

It never caused us problems, because we build on Macs, but apparently
if you cross-compile from Linux with some Mac compiler SDK thing, then
things break?

This was added in https://golang.org/cl/5700083 for #3131, and the
intent at the time was to pin to exactly 10.6. So it wasn't a mistake,
but it is definitely outdated.

Given that we now support 10.8 as the min, update it to 1080.

go/types: avoid redundant call to recordUse for anonymous fields · 2c6949ec

Anonymous fields are type expressions, and Checker.typexpr already
correctly records uses within them. There's no need for a second

net/http: speed up tests, use t.Parallel when it's safe · cd670a61

Brad Fitzpatrick authored Nov 04, 2016

Before: 8.9 seconds for go test -short
 After: 2.8 seconds

There are still 250 tests without t.Parallel, but I got the important
onces using a script:

    $ go test -short -v 2>&1 | go run ~/slowtests.go

Where slowtests.go is https://play.golang.org/p/9mh5Wg1nLN

The remaining 250 (the output lines from slowtests.go) all have a
reported duration of 0ms, except one 50ms test which has to be serial.

Where tests can't be parallel, I left a comment at the top saying why,
so people don't add t.Parallel later and get surprised at failures.

net/http: tweak the new Client 307/308 redirect behavior a bit · 3440c7bc

Brad Fitzpatrick authored Nov 03, 2016

This CL tweaks the new (unreleased) 307/308 support added in
https://golang.org/cl/29852 for #10767.

Change 1: if a 307/308 response doesn't have a Location header in its
response (as observed in the wild in #17773), just do what we used to
do in Go 1.7 and earlier, and don't try to follow that redirect.

Change 2: don't follow a 307/308 if we sent a body on the first
request and the caller's Request.GetBody func is nil so we can't
"rewind" the body to send it again.

Updates #17773 (will be fixed more elsewhere)

runtime: 8-byte align the heap_live field for atomic access · d3a3b74a

Vladimir Stefanovic authored Aug 31, 2016

mheap_.heap_live is an atomically accessed uint64. It is currently not 8-byte
aligned on 32-bit platforms, which has been okay because it's only accessed via
Xadd64, which doesn't require alignment on 386 or ARM32. However, Xadd64 on
MIPS32 does require 8-byte alignment.

Add a padding field to force 8-byte alignment of heap_live and prevent an
alignment check crash on MIPS32.

net/http: support If-Match in ServeContent · f3862742

Dan Harrington authored Oct 25, 2016

- Added support for If-Match and If-Unmodified-Since.
- Precondition checks now more strictly follow RFC 7232 section 6, which
affects precedence when multiple condition headers are present.
- When serving a 304, Last-Modified header is now removed when no ETag is
present (as suggested by RFC 7232 section 4.1).
- If-None-Match supports multiple ETags.
- ETag comparison now correctly handles weak ETags.

Fixes #17572
