Brad Fitzpatrick 901005e8fc net/http: deflake TestClientTimeout_Headers_h2 on Windows
The client code was using time.Now() (wall time) to determine whether
the cause of a non-nil error meant that a timeout had occured. But on
Windows, the clock used for timers (time.After, time.Sleep, etc) is
much more accurate than the time.Now clock, which doesn't update
often.

But it turns out that as of the recent https://golang.org/cl/32478 we
already have the answer available easily. It just wasn't in scope.

Instead of passing this information along by decorating the errors
(risky this late in Go 1.8, especially with #15935 unresolved), just
passing along the "didTimeout" func internally for now. We can remove
that later in Go 1.9 if we overhaul Transport errors.

Fixes #18287 (I hope)

Tilman Dilo 1657d76d5b cmd/vet: fix panic and handling of XML in struct field tag check
The check for duplicate struct field tags introduced in CL 16704
triggers a panic when an anonymous struct field with a duplicate name
is encountered. For such a field, the names slice of the ast.Field is
nil but accessed regardless to generate the warning message.

Additionally, the check produces false positives for XML tags in some
cases:

- When fields are encoded as XML attributes, a warning is produced when
  an attribute reuses a name previously used for an element.

  Example:
    type Foo struct {
        First int `xml:"a"`
        NoDup int `xml:"a,attr"` // warning about reuse of "a"
    }

- When XMLName is used to set the name of the enclosing struct element,
  it is treated as a regular struct field.

  Example:
    type Bar struct {
        XMLName xml.Name `xml:"a"`
        NoDup   int      `xml:"a"` // warning about reuse of "a"
    }

This commit addresses all three issues. The panic is avoided by using
the type name instead of the field name for anonymous struct fields when
generating the warning message. An additional namespace for checking XML
attribute names separately from element names is introduced. Lastly,
fields named XMLName are excluded from the check for duplicate tags.

Joel Sing f91ddaabe6 runtime, syscall: update openbsd for changes to syskill
Change the openbsd runtime to use the current sys_kill and sys_thrkill
system calls.

Prior to OpenBSD 5.9 the sys_kill system call could be used with both
processes and threads. In OpenBSD 5.9 this functionality was split into
a sys_kill system call for processes (with a new syscall number) and a
sys_thrkill system call for threads. The original/legacy system call was
retained in OpenBSD 5.9 and OpenBSD 6.0, however has been removed and
will not exist in the upcoming OpenBSD 6.1 release.

Note: This change is needed to make Go work on OpenBSD 6.1 (to be
released in May 2017) and should be included in the Go 1.8 release.
This change also drops support for OpenBSD 5.8, which is already an
unsupported OpenBSD release.

The pclntable contains pointers to functions. If the function symbol
is exported in a plugin, and there is a matching symbol in the host
binary, then the pclntable of a plugin ends up pointing at the
function in the host module.

This doesn't work because the traceback code expects the pointer to
be in the same module space as the PC value.

So don't export functions that might overlap with the host binary.
This way the pointer stays in its module.

Brad Fitzpatrick 9296d4efe7 net/http: don't retry Transport requests if they have a body
This rolls back https://golang.org/cl/27117 partly, softening it so it
only retries POST/PUT/DELETE etc requests where there's no Body (nil
or NoBody). This is a little useless, since most idempotent requests
have a body (except maybe DELETE), but it's late in the Go 1.8 release
cycle and I want to do the proper fix.

The proper fix will look like what we did for http2 and only retrying
the request if Request.GetBody is defined, and then creating a new request
for the next attempt. See https://golang.org/cl/33971 for the http2 fix.

Joe Tsai 291254414b io: fix MultiReader panic on nil reader.
The combination of two prior CLs can cause panics:
* CL/17873: make chained multiReader Read more efficient
* CL/28533: make MultiReader nil exhausted Readers for earlier GC

The first CL allows MultiReader to "inherit" another MultiReader's list of Readers
for efficiency reasons. This is problematic when combined with the
later CL since that can set prior Readers in that list to nil for GC reasons.
This causes panics when two MultiReaders are used together (even synchronously).

To fix this, rather than setting consumed Readers as nil, we set them with
a special eofReader that always returns EOF.

Fixes #18232

Austin Clements 01c6a19e04 runtime: add number of forced GCs to MemStats
This adds a counter for the number of times the application forced a
GC by, e.g., calling runtime.GC(). This is useful for detecting
applications that are overusing/abusing runtime.GC() or
debug.FreeOSMemory().

Fixes #18217.

Lynn Boger 6623988eb7 cmd/link: fix sym sect when splitting text on ppc64le
While processing a symbol for a function, if it is determined
that a function would make the text section too large then
a new text section is created and the address of the function
is in the new text section.  But the symbol for the function
is marked as being in the previous text section, causing
incorrect codegen for the function and leading to a segv if
that function is called.  This adds code to set the sym.Sect
field to the new section if a new one is created.  Note that
this problem only happens at the point where a new section is
created.

Keith Randall 1ea60c136a runtime: on stack copy, adjust BP
When we copy the stack, we need to adjust all BPs.
We correctly adjust the ones on the stack, but we also
need to adjust the one that is in g.sched.bp.

Like CL 33754, no test as only kernel-gathered profiles will notice.
Tests will come (in 1.9) with the implementation of #16638.

The invariant should hold that every frame pointer points to
somewhere within its stack.  After this CL, it is mostly true, but
something about cgo breaks it.  The runtime checks are disabled
until I figure that out.

Update #16638
Fixes #18174
