GetClientCertificate field
Using GetClientCertificate with the http client is currently completely
broken because inside the transport we clone the tls.Config and pass it
off to the tls.Client. Since tls.Config.Clone() does not pass forward
the GetClientCertificate field, GetClientCertificate is ignored in this
context.
Fixes #19264

args on ARM64
Args may be not at 8-byte aligned offset to SP. When the stack
frame is large, folding the offset of args may cause large
unaligned offsets that does not fit in a machine instruction on
ARM64. Therefore disable folding offsets for args.
This has small performance impact (see below). A better fix would
be letting the assembler backend fix up the offset by loading it
into a register if it doesn't fit into an instruction. And the
compiler can simply generate large load/stores with offset. Since
in most of the cases the offset is aligned or the stack frame is
small, it can fit in an instruction and no fixup is needed. But
this is too complicated for Go 1.8.

into branch conditions
A type conversion inserted between MOVD{LT,LE,GT,GE,EQ,NE} and CMPWconst
by CL 36256 broke the rewrite rule designed to merge the two.
This results in simple for loops (e.g. for i := 0; i < N; i++ {})
emitting two comparisons instead of one, plus a conditional move.
This CL explicitly types the input to CMPWconst so that the type conversion
can be omitted. It also adds a test to check that conditional moves aren't
emitted for loops with 'less than' conditions (i.e. i < N) on s390x.
Fixes #19227.

avoid possible deadlock
We have seen one instance of a production job suddenly spinning to
100% CPU and becoming unresponsive. In that one instance, a SIGQUIT
was sent after 328 minutes of spinning, and the stacks showed a single
goroutine in "IO wait (scan)" state.
Looking for things that might get stuck if a goroutine got stuck in
scanning a stack, we found that injectglist does:
lock(&sched.lock)
var n int
for n = 0; glist != nil; n++ {
gp := glist
glist = gp.schedlink.ptr()
casgstatus(gp, _Gwaiting, _Grunnable)
globrunqput(gp)
}
unlock(&sched.lock)
and that casgstatus spins on gp.atomicstatus until the _Gscan bit goes
away. Essentially, this code locks sched.lock and then while holding
sched.lock, waits to lock gp.atomicstatus.
The code that is doing the scan is:
if castogscanstatus(gp, s, s|_Gscan) {
if !gp.gcscandone {
scanstack(gp, gcw)
gp.gcscandone = true
}
restartg(gp)
break loop
}
More analysis showed that scanstack can, in a rare case, end up
calling back into code that acquires sched.lock. For example:
runtime.scanstack at proc.go:866
calls runtime.gentraceback at mgcmark.go:842
calls runtime.scanstack$1 at traceback.go:378
calls runtime.scanframeworker at mgcmark.go:819
calls runtime.scanblock at mgcmark.go:904
calls runtime.greyobject at mgcmark.go:1221
calls (*runtime.gcWork).put at mgcmark.go:1412
calls (*runtime.gcControllerState).enlistWorker at mgcwork.go:127
calls runtime.wakep at mgc.go:632
calls runtime.startm at proc.go:1779
acquires runtime.sched.lock at proc.go:1675
This path was found with an automated deadlock-detecting tool.
There are many such paths but they all go through enlistWorker -> wakep.
The evidence strongly suggests that one of these paths is what caused
the deadlock we observed. We're running those jobs with
GOTRACEBACK=crash now to try to get more information if it happens
again.
Further refinement and analysis shows that if we drop the wakep call
from enlistWorker, the remaining few deadlock cycles found by the tool
are all false positives caused by not understanding the effect of calls
to func variables.
The enlistWorker -> wakep call was intended only as a performance
optimization, it rarely executes, and if it does execute at just the
wrong time it can (and plausibly did) cause the deadlock we saw.
Comment it out, to avoid the potential deadlock.
Fixes #19112.
Unfixes #14179.

This change removes the punitive language and anonymous reporting mechanism
from the Code of Conduct document. Read on for the rationale.
More than a year has passed since the Go Code of Conduct was introduced.
In that time, there have been a small number (<30) of reports to the Working Group.
Some reports we handled well, with positive outcomes for all involved.
A few reports we handled badly, resulting in hurt feelings and a bad
experience for all involved.
On reflection, the reports that had positive outcomes were ones where the
Working Group took the role of advisor/facilitator, listening to complaints and
providing suggestions and advice to the parties involved.
The reports that had negative outcomes were ones where the subject of the
report felt threatened by the Working Group and Code of Conduct.
After some discussion among the Working Group, we saw that we are most
effective as facilitators, rather than disciplinarians. The various Go spaces
already have moderators; this change to the CoC acknowledges their authority
and places the group in a purely advisory role. If an incident is
reported to the group we may provide information to or make a
suggestion the moderators, but the Working Group need not (and should not) have
any authority to take disciplinary action.
In short, we want it to be clear that the Working Group are here to help
resolve conflict, period.
The second change made here is the removal of the anonymous reporting mechanism.
To date, the quality of anonymous reports has been low, and with no way to
reach out to the reporter for more information there is often very little we
can do in response. Removing this one-way reporting mechanism strengthens the
message that the Working Group are here to facilitate a constructive dialogue.

chardata, comment, innerxml fields
The new tests in this CL have been checked against Go 1.7 as well
and all pass in Go 1.7, with the one exception noted in a comment
(an intentional change to omitempty already present before this CL).
CL 15684 made the intentional change to omitempty.
This CL fixes bugs introduced along the way.
Most of these are corner cases that are arguably not that important,
but they've always worked all the way back to Go 1, and someone
cared enough to file #19063. The most significant problem found
while adding tests is that in the case of a nil *string field with
`xml:",chardata"`, the existing code silently stops processing not just
that field but the entire remainder of the struct.
Even if #19063 were not worth fixing, this chardata bug would be.
Fixes #19063.

canceled
Previously it was intended that Rows.Scan would return
an error and Rows.Err would return nil. This was problematic
because drivers could not differentiate between a normal
Rows.Close or a context cancel close.
The alternative is to require drivers to return a Scan to return
an error if the driver is closed while there are still rows to be read.
This is currently not how several drivers currently work and may be
difficult to detect when there are additional rows.
At the same time guard the the Rows.lasterr and prevent a close
while a Rows operation is active.
For the drivers that do not have Context methods, do not check for
context cancelation after the operation, but before for any operation
that may modify the database state.

We added CentOS 7's /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem

Now we have #18813, where CentOS 6 apparently has both that file
and /etc/pki/tls/certs/ca-bundle.crt, and the latter is complete while
the former is not.
Moving the new CentOS 7 file to the bottom of the list should fix both
problems: the CentOS 7 system that didn't have any of the other files
in the list will still find the new one, and existing systems will still
keep using what they were using instead of preferring the new path
that may or may not be complete on some systems.

The compiler did not emit write barrier for assigning global with
struct literal, like global = T{} where T contains pointer.
The relevant code path is:
walkexpr OAS var_ OSTRUCTLIT
oaslit
anylit OSTRUCTLIT
walkexpr OAS var_ nil
return without adding write barrier
return true
break (without adding write barrier)
This CL makes oaslit not apply to globals. See also CL
https://go-review.googlesource.com/c/36355/ for an alternative
fix.
The downside of this is that it generates static data for zeroing
struct now. Also this only covers global. If there is any lurking
bug with implicit zeroing other than globals, this doesn't fix.

for incorrect if statement
This is a follow-up on https://go-review.googlesource.com/36470
and leads to a more stable fix. The above CL relied on filtering
of multiple errors on the same line to avoid more than one error
for an `if` statement of the form `if a := 10 {}`. This CL avoids
the secondary error ("missing condition in if statement") in the
first place.
For #18915.

This CL fixes two issues:
1. Load ops were initially always lowered to unsigned loads, even
for signed types. This was fine by itself however LoadReg ops
(used to re-load spilled values) were lowered to signed loads
for signed types. This meant that spills could invalidate
optimizations that assumed the original unsigned load.
2. Types were not always being maintained correctly through rules
designed to eliminate unnecessary zero and sign extensions.
Updates #18906 and fixes #18958 (backport of CL 36256 to 1.8).

First steps towards defining type aliases in the spec.
This is a nomenclature clarification, not a language change.
The spec used all three terms 'embedded type', 'anonymous field',
and 'embedded field'. Users where using the terms inconsistently.
The notion of an 'anonymous' field was always misleading since they
always had a de-facto name. With type aliases that name becomes even
more important because we may have different names for the same type.
Use the term 'embedded field' consistently and remove competing
terminology.
For #18130.

The test.bash script in misc/cgo/testsanitizers use GOOS, not GOHOSTOS.
Fix the dist check from gohostos to goos accordingly.
The error was masked on the builders because they run on a darwin host
where the sanitizers tests never ran.
With this change, the Android test suite completes successfully on
Android/amd64.

I filed https://gcc.gnu.org/PR79289 for the GCC problem. I think this
is a bug in GCC, and it may be fixed before the final GCC 7 release.
This CL is correct either way.

Previously the following could happen, though in practice it would
be rare.
Goroutine 1:
(*Tx).QueryContext begins a query, passing in userContext
Goroutine 2:
(*Tx).awaitDone starts to wait on the context derived from the passed in context
Goroutine 1:
(*Tx).grabConn returns a valid (*driverConn)
The (*driverConn) passes to (*DB).queryConn
Goroutine 3:
userContext is canceled
Goroutine 2:
(*Tx).awaitDone unblocks and calls (*Tx).rollback
(*driverConn).finalClose obtains dc.Mutex
(*driverConn).finalClose sets dc.ci = nil
Goroutine 1:
(*DB).queryConn obtains dc.Mutex in withLock
ctxDriverPrepare accepts dc.ci which is now nil
ctxCriverPrepare panics on the nil ci
The fix for this is to guard the Tx methods with a RWLock
holding it exclusivly when closing the Tx and holding a read lock
when executing a query.

This fix is less pervasive than it seems. The only change affecting
formatting is on printer.go:760. The remaining changes have no effect
on formatting since the value of p.level is ignored except on this
specific line.
The remaining changes are:
- renamed adjBlock to funcBody since that's how it is used
- introduced new printer field 'level' tracking the composite
literal nesting level
- update/restore the composite literal nesting level as needed
Fixes #18782.

Modules appear in the moduledata linked list in the order they are
loaded by the dynamic loader, with one exception: the
firstmoduledata itself the module that contains the runtime.
This is not always the first module (when using -buildmode=shared,
it is typically libstd.so, the second module).
The order matters for typelinksinit, so we swap the first module
with whatever module contains the main function.
