      cmd/compile: fix package initialization ordering · 5d0d87ae
      Matthew Dempsky authored 
      This CL rewrites cmd/compile's package-level initialization ordering
algorithm to be compliant with the Go spec. See documentation in
initorder.go for details.

Incidentally, this CL also improves fidelity of initialization loop
diagnostics by including referenced functions in the emitted output
like go/types does.

Fixes #22326.

      cmd/link: do not generate NT 4 compatibility binaries · e883d000
      Jason A. Donenfeld authored 
      Incredibly, the subsystem version numbers in the PE header influence how
win32k handles various syscalls. The first time a win32k syscall is
invoked and the kernel upgrades the thread object to a tagTHREADINFO
with all of the lovely undocumented UI members and such, it sets the
dwExpWinVer member (offset 624 in Windows 10 build 1809) to the result
of RtlGetExpWinVer(PsGetProcessSectionBaseAddress(proc)).
RtlGetExpWinVer, also undocumented, then calls into the undocumented
RtlImageNtHeader function, which returns a fortunately documented
IMAGE_NT_HEADERS structure. It uses the subsystem members in there to
set the dwExpWinVer member of our newly minted tagTHREADINFO object.
Later, functions like SendInput consult this to vary their behaviors and
return values. In fact, littered through out win32k are checks like `if
(gsti->dwExpWinVer >= 0x501) { ... }`.

I don't think Go ever supported NT 4.0. These days the minimum version
is Windows 7, which is 6.1. So, let's set the version numbers in the PE
header at that, which should give us the behavior that MSDN advertises
for various functions, as opposed to bizarre archeological remnants.

Interestingly, I suspect that most people never noticed the brokenness,
because most people trying to do serious Win32 UI stuff wind up linking
in cgo, if not for actually using C, then just to have a larger system
stack so that the stack doesn't get corrupted by various UI functions.
When MingW is used, the PE header gets a later version. But recently
there's been a bug report of some people trying to do more modest UI
manipulation using SendInput in a setting where this cgo hack probably
isn't required, so they ran into the weird historical compatibility
stuff.

Fixes #31685

      net/http: quiet some log spam in tests · 770746af
      Brad Fitzpatrick authored 
      One of these tests creates a bunch of connections concurrently, then
discovers it doesn't need them all, which then makes the server log
that the client went away midway through the TLS handshake. Perhaps
the server should recognize that as a case not worthy of logging
about, but this is a safer way to eliminate the stderr spam during go
test for now.

The other test's client gives up on its connection and closes it,
similarly confusing the server.

      cmd/compile: process blocks containing only dead values in fuseIf · ddb5d0db
      Josh Bleecher Snyder authored 
      The code in #29218 resulted in an If block containing only its control.
That block was then converted by fuseIf into a plain block;
as a result, that control value was dead.
However, the control value was still present in b.Values.
This prevented further fusing of that block.

This change beefs up the check in fuseIf to allow fusing
blocks that contain only dead values (if any).
In the case of #29218, this enables enough extra
fusing that the control value could be eliminated,
allowing all values in turn to be eliminated.

This change also fuses 34 new blocks during make.bash.

It is not clear that this fixes every variant of #29218,
but it is a reasonable standalone change.
And code like #29218 is rare and fundamentally buggy,
so we can handle new instances if/when they actually occur.

Fixes #29218

      cmd/doc: always print package clause except for commands · f736de04
      Rob Pike authored 
      There was an implicit heuristic before about when to print the
package clause or omit it, but it was undocumented and confusing.
Get rid of it and print it always unless asking for the package
docs for a command, which are more of a usage message than a
programming question. This simplifies the processing.

There are several paths to the output, so to put the fix in one
place we place a wrapper before the output buffer than adds the
clause when Write is first called.

The tests don't verify this behavior, but they didn't before either.
Unsure what the right approach is but this will do for now.

      runtime: remove VDSO fallback test and benchmarks · 15311922
      Ian Lance Taylor authored 
      These tests assume that it is OK to switch between time implementations,
but the clock_gettime call uses CLOCK_MONOTONIC and the fallback call,
gettimeofday, uses CLOCK_REALTIME. Disabling the clock_gettime call means
that calls to nanotime will start returning very different values.
This breaks the new timer code, which assumes that nanotime will return
a consistently increasing value.

This test is not very useful in any case as it doesn't check the results.

Removing this file also removes BenchmarkTimeNow, which is a duplicate
of BenchmarkNow in the time package.

Also, we forgot to include the fallback to direct for when
the proxy serves a 404. Add and test that too.

Also add HTTP fetch information to -x build flag output.
(It does not belong in the -v output, despite the GOPATH go get
command doing this.)

      cmd, runtime: remove PC_F & PC_B globals on Wasm · 496b8dbb
      Cherry Zhang authored 
      Following the previous CL, this removes more global variables on
Wasm.

PC_B is used mostly for intra-function jumps, and for a function
telling its callee where to start or resume. This usage can be
served by a parameter. The top level loop (wasm_pc_f_loop) uses
PC_B for resuming a function. This value is either set by gogo,
or loaded from the Go stack at function return. Instead of
loading PC_B at each function return, we could make gogo stores
PC_B at the same stack location, and let the top level loop do
the load. This way, we don't need to use global PC_B to
communicate with the top level loop, and we can replace global
PC_B with a parameter.

PC_F is similar. It is even more so in that the only reader is
the top level loop. Let the top level loop read it from the stack,
and we can get rid of PC_F entirely.

PC_F and PC_B are used less entensively as SP, so this CL has
smaller performance gain.

      runtime: ensure mheap lock stack growth invariant is maintained · 7ed7669c
      Michael Anthony Knyszek authored 
      Currently there's an invariant in the runtime wherein the heap lock
can only be acquired on the system stack, otherwise a self-deadlock
could occur if the stack grows while the lock is held.

This invariant is upheld and documented in a number of situations (e.g.
allocManual, freeManual) but there are other places where the invariant
is either not maintained at all which risks self-deadlock (e.g.
setGCPercent, gcResetMarkState, allocmcache) or is maintained but
undocumented (e.g. gcSweep, readGCStats_m).

This change adds go:systemstack to any function that acquires the heap
lock or adds a systemstack(func() { ... }) around the critical section,
where appropriate. It also documents the invariant on (*mheap).lock
directly and updates repetitive documentation to refer to that comment.

Fixes #32105.

      strings: clarify example of ContainsAny · db325553
      Martin Sucha authored 
      I have seen code that literally copied the example like this:

    if strings.ContainsAny(s, "1 & 2 & 3") {

The developer apparently thought that this is the way to
specify multiple characters and I noticed this pattern
being used in the example. Let's update the example so
that it's clear how multiple Unicode code points should
be specified.

      syscall/js: replace TypedArrayOf with CopyBytesToGo/CopyBytesToJS · c468ad04
      Richard Musiol authored 
      The typed arrays returned by TypedArrayOf were backed by WebAssembly
memory. They became invalid each time we grow the WebAssembly memory.
This made them very error prone and hard to use correctly.

This change removes TypedArrayOf completely and instead introduces
CopyBytesToGo and CopyBytesToJS for copying bytes between a byte
slice and an Uint8Array. This breaking change is still allowed for
the syscall/js package.

Fixes #31980.
Fixes #31812.

      Utilize KDSA when available. This guarantees constant time operation on all three curves mentioned,
and is faster than conventional assembly. The IBM Z model(s) that support KDSA as used in this CL
are not yet publicly available, and so we are unable to release performance data at this time.
