      runtime: fix deadlock in TestCrashDumpsAllThreads · 7c22af83
      Austin Clements authored 
      TestCrashDumpsAllThreads carefully sets the number of Ps to one
greater than the number of non-preemptible loops it starts so that the
main goroutine can continue to run (necessary because of #10958).
However, if GC starts, it can take over that one spare P and lock up
the system while waiting for the non-preemptible loops, causing the
test to eventually time out. This deadlock is easily reproducible if
you run the runtime test with GOGC=1.

Fix this by forcing GOGC=off when running this test.

      cmd/compile: print struct tags in var decl in inlined func body · feb2a5d6
      Russ Cox authored 
      This bug was introduced in golang.org/cl/18217,
while trying to fix #13777.

Originally I wanted to just disable inlining for the case
being handled incorrectly, but it's fairly difficult to detect
and much easier just to fix. Since the case being handled
incorrectly was inlined correctly in Go 1.5, not inlining it
would also be somewhat of a regression.
So just fix it.

Test case copied from Ian's CL 19520.

The mistake to worry about in this CL would be relaxing
the condition too much (we now print the note more often
than we did yesterday). To confirm that we'd catch this mistake,
I checked that changing (!fmtbody || !t.Funarg) to (true) does
cause fixedbugs/issue13777.go to fail. And putting it back
to what is written in this CL makes that test pass again
as well as the new fixedbugs/issue14331.go.
So I believe that the new condition is correct for both constraints.

Fixes #14331.

      net: make TestInterfaceAddrsWithNetsh more robust · e136cac4
      Alex Brainman authored 
      TestInterfaceAddrsWithNetsh invokes Windows netsh command passing
it a particular interface name. This approach somehow does not work
on some computers (see issue for details). Change that to call netsh
without specifying any interface name. This provides output for all
interfaces available. So we can achieve same goal parsing this output.
Also makes test faster because we only need to invoke netsh once.

Fixes #14130.

      runtime: show panics in traceback · 0c02bc00
      Austin Clements authored 
      We used to include panic calls in tracebacks; however, when
runtime.panic was renamed to runtime.gopanic in the conversion of the
runtime to Go, we missed the special case in showframe that includes
panic calls even though they're in package runtime.

Fix the function name check in showframe (and, while we're here, fix
the other check for "runtime.panic" in runtime/pprof). Since the
"runtime.gopanic" name doesn't match what users call panic and hence
isn't very user-friendly, make traceback rewrite it to just "panic".

Updates #5832, #13857. Fixes #14315.

      doc: tweak Go 1.6 GC release notes · 62fad436
      Austin Clements authored 
      Go 1.6 significantly improves pause times for large heaps, but it
improves them in many other situations as well, such as when goroutine
churn is high, allocation rate is high, or when there are many
finalizers. Hence, make the statement about pause times a bit more
general.
