A Rat is represented via a quotient a/b where a and b are Int values.
To make it possible to use an uninitialized Rat value (with a and b
uninitialized and thus == 0), the implementation treats a 0 denominator
as 1.
Rat.Num and Rat.Denom return pointers to these values a and b. Because
b may be 0, Rat.Denom used to first initialize it to 1 and thus produce
an undesirable side-effect (by changing the Rat's denominator).
This CL changes Denom to return a new (not shared) *Int with value 1
in the rare case where the Rat was not initialized. This eliminates
the side effect and returns the correct denominator value.
While this is changing behavior of the API, the impact should now be
minor because together with (prior) CL https://golang.org/cl/202997,
which initializes Rats ASAP, Denom is unlikely used to access the
denominator of an uninitialized (and thus 0) Rat. Any operation that
will somehow set a Rat value will ensure that the denominator is not 0.
Fixes #36689.
For #33792.
For #3521.

A Rat is represented via a quotient a/b where a and b are Int values.
To make it possible to use an uninitialized Rat value (with a and b
uninitialized and thus == 0), the implementation treats a 0 denominator
as 1.
For each operation we check if the denominator is 0, and then treat
it as 1 (if necessary). Operations that create a new Rat result,
normalize that value such that a result denominator 1 is represened
as 0 again.
This CL changes this behavior slightly: 0 denominators are still
interpreted as 1, but whenever we (safely) can, we set an uninitialized
0 denominator to 1. This simplifies the code overall.
Also: Improved some doc strings.

When a locked M wants to start a new M, it hands off to the template
thread to actually call clone and start the thread. The template thread
is lazily created the first time a thread is locked (or if cgo is in
use).
stoplockedm will release the P (_Pidle), then call handoffp to give the
P to another M. In the case of a pending STW, one of two things can
happen:
1. handoffp starts an M, which does acquirep followed by schedule, which
will finally enter _Pgcstop.
2. handoffp immediately enters _Pgcstop. This only occurs if the P has
no local work, GC work, and no spinning M is required.
If handoffp starts an M, and must create a new M to do so, then newm
will simply queue the M on newmHandoff for the template thread to do the
clone.
When a stop-the-world is required, stopTheWorldWithSema will start the
stop and then wait for all Ps to enter _Pgcstop. If the template thread
is not fully created because startTemplateThread gets stopped, then
another stoplockedm may queue an M that will never get created, and the
handoff P will never leave _Pidle. Thus stopTheWorldWithSema will wait
forever.
A sequence to trigger this hang when STW occurs can be visualized with
two threads:
T1 T2
------------------------------- -----------------------------
LockOSThread LockOSThread
haveTemplateThread == 0
startTemplateThread
haveTemplateThread = 1
newm haveTemplateThread == 1
preempt -> schedule g.m.lockedExt++
gcstopm -> _Pgcstop g.m.lockedg = ...
park g.lockedm = ...
return
... (any code)
preempt -> schedule
stoplockedm
releasep -> _Pidle
handoffp
startm (first 3 handoffp cases)
newm
g.m.lockedExt != 0
Add to newmHandoff, return
park
Note that the P in T2 is stuck sitting in _Pidle. Since the template
thread isn't running, the new M will not be started complete the
transition to _Pgcstop.
To resolve this, we disable preemption around the assignment of
haveTemplateThread and the creation of the template thread in order to
guarantee that if handTemplateThread is set then the template thread
will eventually exist, in the presence of stops.

in regalloc
When deallocating the input register to a phi so that the phi
itself could be allocated to that register the code was also
deallocating all copies of that phi input value. Those copies
of the value could still be live and if they were the register
allocator could reuse them incorrectly to hold speculative
copies of other phi inputs. This causes strange bugs.
No test because this is a very obscure scenario that is hard
to replicate but CL 228060 adds an assertion to the compiler
that does trigger when running the std tests on linux/s390x
without this CL applied. Hopefully that assertion will prevent
future regressions.
Fixes #38442.

materializeGCProg allocates a temporary buffer for unrolling a GC
program. Unfortunately, when computing the size of the buffer, it
rounds *down* the number of bytes needed to store bitmap before
rounding up the number of pages needed to store those bytes. The fact
that it rounds up to pages usually mitigates the rounding down, but
the type from #37470 exists right on the boundary where this doesn't
work:
type Sequencer struct {
htable [1 << 17]uint32
buf []byte
}
On 64-bit, this GC bitmap is exactly 8 KiB of zeros, followed by three
one bits. Hence, this needs 8193 bytes of storage, but the current
math in materializeGCProg rounds *down* the three one bits to 8192
bytes. Since this is exactly pageSize, the next step of rounding up to
the page size doesn't mitigate this error, and materializeGCProg
allocates a buffer that is one byte too small. runGCProg then writes
one byte past the end of this buffer, causing either a segfault (if
you're lucky!) or memory corruption.
Updates #37470.
Fixes #37483.

Currently, we extract module zip files to temporary directories, then
atomically rename them into place. On Windows, this can fail with
ERROR_ACCESS_DENIED if another process (antivirus) has files open
before the rename. In CL 220978, we repeated the rename operation in a
loop over 500 ms, but this didn't solve the problem for everyone.
A better solution will extract module zip files to their permanent
locations in the cache and will keep a ".partial" marker file,
indicating when a module hasn't been fully extracted (CL 221157).
This approach is not safe if current versions of Go access the module
cache concurrently, since the module directory is detected with a
single os.Stat.
In the interim, this CL makes two changes:
1. Flaky file system operations are repeated over 2000 ms to reduce
the chance of this error occurring.
2. cmd/go will now check for .partial files created by future
versions. If a .partial file is found, it will lock the lock file,
then remove the .partial file and directory if needed.
After some time has passed and Go versions lacking this CL are no
longer supported, we can start extracting module zip files in place.

These non-short Windows test failures were resolved fully in CL 206144.
Both TestScript/build_trimpath and TestScript/version tests can be fixed
by backporting the changes to test scripts only, so that is done here.
Fixing TestScript/mod_list_dir requires backporting non-test changes in
addition to the test script changes, which is unlikely to be appropriate
this late in Go 1.13 release cycle. A failing test can cover up other
regressions, so skip this known failing test to fix the builder.

when present
Builds upon the changes from #32000 which supported sourcing environment
variables for a new process from the environment of a Windows user token
when supplied.
But due to the logic of os/exec, the Env field of a process was
always non-nil when it reached that change.
This change moves the logic up to os/exec, specifically when
os.ProcAttr is being built for the os.StartProcess call, this
ensures that if a user token has been supplied and no Env slice has
been provided on the command it will be sourced from the user's
environment.
If no token is provided, or the program is compiled for any other
platform than Windows, the default environment will be sourced from
syscall.Environ().

TestWalkFullRegistry due to false assumptions
This test's existence was predicated upon assumptions about the full
range of known data types and known data into those types. However,
we've learned from Microsoft that there are several undocumented secret
registry types that are in use by various parts of Windows, and we've
learned from inspection that many Microsoft uses of registry types don't
strictly adhere to the recommended value size. It's therefore foolhardy
to make any assumptions about what goes in and out of the registry, and
so this test, as well as its "blacklist", are meaningless.

Old trace viewer stopped working with Chrome M80+ because the
old trace viewer heavily depended on WebComponents V0 which are deprecated.
Trace viewer recently migrated to use WebComponents V0 polyfill
(crbug.com/1036492). This CL brings in the newly updated trace_viewer_full.html
(sync'd @ 9508452e)
and updates the javascript snippet included in the /trace endpoint
to use the polyfill.
This brings in webcomponents.min.js copied from
https://chromium.googlesource.com/catapult/+/9508452e18f130c98499cb4c4f1e1efaedee8962/third_party/polymer/components/webcomponentsjs/webcomponents.min.js
That is necessary because the /trace endpoint needs to import
the vulcanized trace_viewer_full.html.
It's possible that some features are not working correctly with
this polyfill. In that case, report the issue to crbug.com/1036492.
There will be a warning message in the UI (yellow banner above the timeline)
which can be hidden by clicking the 'hide' button.
This allows to render the trace in browsers other than chrome in theory,
but I observed some buttons and functions still don't work outside
chrome.

Regression tests for #24161 use a macro to conditionally compile some

We get duplicate definitions when building this test with
CGO_CFLAGS=-mmacosx-version-min=10.x where 10.x < 10.12. With this
change, we use a different macro, __MAC_OS_X_VERSION_MAX_ALLOWED__,
which tests the SDK version instead of the minimum macOS version. This
checks whether these definitions are present in headers.
After this change, 'go tool dist test cgo_test' should pass with

'go get all' was run in this test without -d. This caused some std
packages to be reinstalled if the test is run in a slightly different
configuration than make.bash was run. run.bash would fail in some
situations because of this. Nothing in the cmd/go tests should modify
installed std or cmd packages.

security fix for 32-bit archs
cryptobyte: fix panic due to malformed ASN.1 inputs on 32-bit archs
When int is 32 bits wide (on 32-bit architectures like 386 and arm), an
overflow could occur, causing a panic, due to malformed ASN.1 being
passed to any of the ASN1 methods of String.
Tested on linux/386 and darwin/amd64.
This fixes CVE-2020-7919 and was found thanks to the Project Wycheproof
test vectors.

verification bypass on Windows
An attacker can trick the Windows system verifier to use a poisoned set
of elliptic curve parameters for a trusted root, allowing it to generate
spoofed signatures. When this happens, the returned chain will present
the unmodified original root, so the actual signatures won't verify (as
they are invalid for the correct parameters). Simply double check them
as a safety measure and mitigation.
Windows users should still install the system security patch ASAP.
This is the same mitigation adopted by Chromium:

ARM64
If a pointer write is not atomic, if the GC is running
concurrently, it may observe a partially updated pointer, which
may point to unallocated or already dead memory. Most pointer
writes, like the store instructions generated by the compiler,
are already atomic. But we still need to be careful in places
like memmove. In memmove, we don't know which bits are pointers
(or too expensive to query), so we ensure that all aligned
pointer-sized units are written atomically.

Updates #36101.

PowerRegisterSuspendResumeNotification on systems with "program time" timer
Systems where PowerRegisterSuspendResumeNotification returns ERROR_
FILE_NOT_FOUND are also systems where nanotime() is on "program time"
rather than "real time". The chain for this is:
powrprof.dll!PowerRegisterSuspendResumeNotification ->
umpdc.dll!PdcPortOpen ->
ntdll.dll!ZwAlpcConnectPort("\\PdcPort") ->
syscall -> ntoskrnl.exe!AlpcpConnectPort
Opening \\.\PdcPort fails with STATUS_OBJECT_NAME_NOT_FOUND when pdc.sys
hasn't been initialized. Pdc.sys also provides the various hooks for
sleep resumption events, which means if it's not loaded, then our "real
time" timer is actually on "program time". Finally STATUS_OBJECT_NAME_
NOT_FOUND is passed through RtlNtStatusToDosError, which returns ERROR_
FILE_NOT_FOUND. Therefore, in the case where the function returns ERROR_
FILE_NOT_FOUND, we don't mind, since the timer we're using will
correspond fine with the lack of sleep resumption notifications. This
applies, for example, to Docker users.

release, only the ones that have been labeled as CherryPickApproved are.
Update the links to the GitHub issue tracker to include a filter on the
CherryPickApproved label, so that the default view shows only the
backports that were included in a given release. This should more useful
to most people than seeing all backports (considered and approved).
Do this only for Go 1.9.1 and newer releases, as that is when we started
using the CherryPickCandidate and CherryPickApproved labels.

If a compilation has multiple text sections, code in
textOff must compare the offset argument against the range
for each text section to determine which one it is in.
The comparison looks like this:
if uintptr(off) >= sectaddr && uintptr(off) <= sectaddr+sectlen
If the off value being compared is equal to sectaddr+sectlen then it
is not within the range of the text section but after it. The
comparison should be just '<'.
