Sub provides a convenient way to refer to a subdirectory
automatically in future operations, like Unix's chdir(2).
The CL also includes updates to fstest to check Sub implementations.
As part of updating fstest, I changed the meaning of TestFS's
expected list to introduce a special case: if you list no expected files,
that means the FS must be empty. In general it's OK not to list all
the expected files, but if you list none, that's almost certainly a
mistake - if your FS were broken and empty, you wouldn't find out.
Making no expected files mean "must be empty" makes the mistake
less likely - if your file system ever worked, then your test will keep
it working.
That change found a testing bug: embedtest was making exactly
that mistake.
Fixes#42322.

Previously, we resolved each argument to 'go get' to a package path or
module path based on what was in the build list at existing versions,
even if the argument specified a different version explicitly. That
resulted in bugs like #37438, in which we variously resolved the wrong
version or guessed the wrong argument type for what is unambiguously a
package argument at the requested version.
We were also using a two-step upgrade/downgrade algorithm, which could
not only upgrade more that is strictly necessary, but could also
unintentionally upgrade *above* the requested versions during the
downgrade step.
This change instead uses an iterative approach, with an explicit
disambiguation step for the (rare) cases where an argument could match
the same package path in multiple modules. We use a hook in the
package loader to halt package loading as soon as an incorrect version
is found — preventing over-resolving — and verify that the result
after applying downgrades successfully obtained the requested versions
of all modules.
Making 'go get' be correct and usable is especially important now that
we are defaulting to read-only mode (#40728), for which we are
recommending 'go get' more heavily.
While I'm in here refactoring, I'm also reworking the API boundary
between the modget and modload packages. Previously, the modget
package edited the build list directly, and the modload package
accepted the edited build list without validation. For lazy loading
(#36460), the modload package will need to maintain additional
metadata about the requirement graph, so it needs tighter control over
the changes to the build list.
As of this change, modget no longer invokes MVS directly, but instead
goes through the modload package. The resulting API gives clearer
reasons in case of updates, which we can use to emit more useful
errors.

In the current (pre-CL) version of the spec, the 2nd last shift
example appears to be using the array declared in the last example.
On a 32-bit platform, that array would have length 0, which would
lead to a panic in the 2nd last example. Also, if this code were
inside a function, it wouldn't compile (array declared after use).
Use an explicitly declared array for that specific shift example.
Also, split out all cases that produce different results for 32-

Setting inittrace=1 causes the runtime to emit a single line to standard error for
each package with init work, summarizing the execution time and memory allocation.
The emitted debug information for init functions can be used to find bottlenecks
or regressions in Go startup performance.
Packages with no init function work (user defined or compiler generated) are omitted.
Tracing plugin inits is not supported as they can execute concurrently. This would
make the implementation of tracing more complex while adding support for a very rare
use case. Plugin inits can be traced separately by testing a main package importing
the plugins package imports explicitly.

Currently, mhdr/methods is emitted with the same len/cap. There's no way
to distinguish between exported and non-exported methods statically.
This CL splits mhdr/methods into two parts, use "len" for number of
exported methods, and "cap" for all methods. This fixes the bug in
issue #22075, which intends to return the number of exported methods but
currently return all methods.
Note that with this encoding, we still can access either
all/exported-only/non-exported-only methods:
mhdr[:cap(mhdr)] // all methods
mhdr // exported methods
mhdr[len(mhdr):cap(mhdr)] // non-exported methods
Thank to Matthew Dempsky (@mdempsky) for suggesting this encoding.

The StripPrefix wrapper strips a prefix string from the request's
URL.Path field, but doesn't touch the RawPath field. This leads to the
confusing situation when StripPrefix handles a request with URL.RawPath
populated (due to some escaped characters in the request path) and the
wrapped request's RawPath contains the prefix but Path does not.
This change modifies StripPrefix to strip the prefix from both Path and
RawPath. If there are escaped characters in the prefix part of the
request URL the stripped handler serves a 404 instead of invoking the
underlying handler with a mismatched Path/RawPath pair.
This is a backward incompatible change for a very small minority of
requests; I would be surprised if anyone is depending on this behavior,
but it is possible. If that's the case, we could make a more
conservative change where the RawPath is trimmed if possible, but when
the prefix contains escaped characters then we don't 404 but rather send
through the invalid Path/RawPath pair as before.

The StdFormat flag was added as part of CL 231461, where the primary aim
was to fix the bug #37476. It's expected that the existing printer modes
only adjust spacing but do not change any of the code text itself. A new
printing flag served as a way for cmd/gofmt and go/format to delegate
a part of formatting work to the printer—where it's more more convenient
and efficient to perform—while maintaining current low-level printing
behavior of go/printer unmodified.
We already have cmd/gofmt and the go/format API that implement standard
formatting of Go source code, so there isn't a need to expose StdFormat
flag to the world, as it can only cause confusion.
Consider that to format source in canonical gofmt style completely it
may require tasks A, B, C to be done. In one version of Go, the printer
may do both A and B, while cmd/gofmt and go/format will do the remaining
task C. In another version, the printer may take on doing just A, while
cmd/gofmt and go/format will perform B and C. This makes it hard to add
a gofmt-like mode to the printer without compromising on above fluidity.
This change prefers to shift back some complexity to the implementation
of the standard library, allowing us to avoid creating the new exported
printing flag just for the internal needs of gofmt and go/format today.
We may still want to re-think the API and consider if something better
should be added, but unfortunately there isn't time for Go 1.15. We are
not adding new APIs now, so we can defer this decision until Go 1.16 or
later, when there is more time.

Restore previously sent SCTs and stapled OCSP response during session
resumption for both TLS 1.2 and 1.3. This behavior is somewhat
complicated for TLS 1.2 as SCTs are sent during the server hello,
so they override what is saved in ClientSessionState. It is likely
that if the server is sending a different set of SCTs there is probably
a reason for doing so, such as a log being retired, or SCT validation
requirements changing, so it makes sense to defer to the server in
that case.

There's been plenty of discussion on the usage of these terms in tech.
I'm not trying to have yet another debate. It's clear that there are
people who are hurt by them and who are made to feel unwelcome by their
use due not to technical reasons but to their historical and social
context. That's simply enough reason to replace them.
Anyway, allowlist and blocklist are more self-explanatory than whitelist
and blacklist, so this change has negative cost.
Didn't change vendored, bundled, and minified files. Nearly all changes
are tests or comments, with a couple renames in cmd/link and cmd/oldlink
which are extremely safe. This should be fine to land during the freeze
without even asking for an exception.

Ctty was always handled as a child descriptor, but in some cases
passing a parent descriptor would also work. This depended on
unpredictable details of the implementation. Reject those cases to
avoid confusion.
Also reject setting both Setctty and Foreground, as they use Ctty
in incompatible ways. It's unlikely that any programs set both fields,

If an I/O operation fails because a deadline was exceeded,
return os.ErrDeadlineExceeded. We used to return poll.ErrTimeout,
an internal error, and told users to check the Timeout method.
However, there are other errors with a Timeout method that returns true,
notably syscall.ETIMEDOUT which is returned for a keep-alive timeout.
Checking errors.Is(err, os.ErrDeadlineExceeded) should permit code
to reliably tell why it failed.
This change does not affect the handling of net.Dialer.Deadline,
nor does it change the handling of net.DialContext when the context
deadline is exceeded. Those cases continue to return an error
reported as "i/o timeout" for which Timeout is true, but that error
is not os.ErrDeadlineExceeded.

unsafe.Pointer safety rule #4 says "The compiler handles a Pointer

analysis, we've always required this be a single conversion
unsafe.Pointer->uintptr conversion, but the corresponding logic in
order is somewhat laxer, allowing arbitrary chains of OCONVNOPs from
unsafe.Pointer to uintptr.
This CL changes order to be stricter to match escape analysis.

Given:
type u struct{}
func (u) M() {}
type t struct { u; u2 u }
var v = reflect.ValueOf(t{})
Package reflect allows:
v.Method(0) // v.M
v.Field(0).Method(0) // v.u.M
but panics from:
v.Field(1).Method(0) // v.u2.M
because u2 is not an exported field. However, u is not an exported
field either, so this is inconsistent.
It seems like this behavior originates from #12367, where it was
decided to allow traversing unexported embedded fields to be able to
access their exported fields, since package reflect doesn't provide an
alternative way to access promoted fields directly.
But extending that logic to promoted *methods* was inappropriate,
because package reflect's normal method handling logic already handles
promoted methods correctly. This CL corrects that mistake.
Fixes#38521.

Importing the time/tzdata package will embed a copy of the IANA

It will increase the size of the binary by about 800K.
You can also build a program with -tags timetzdata to embed the
timezone database in the program being built.
This is a roll forward of CL 224588 which was rolled back due to
test failures. In this version, the test is in the time package,
not the time/tzdata package. That lets us compare the zip file
to the time/tzdata package, ensuring that we are looking at similar

Go build scripts on UNIX (make.bash, all.bash) have not required
GOROOT_BOOTSTRAP since August 2017 (CL 57753). Windows build scripts
have followed suit since CL 96455. Most people building Go will have
a Go toolchain in their PATH and will not need to specify a different
toolchain.
This CL removes the GOROOT_BOOTSTRAP mention from the contribution guide
(it was there for Windows only, but it's not required anymore). The guide
is meant to be light and clear for beginners and is not supposed to be
a reference, so there's not need to keep mentioning GOROOT_BOOTSTRAP.
Also update install-source.html to reflect the current status quo,
where using the PATH is probably the first and most used default, and
GOROOT_BOOTSTRAP is just an option.
