As #61067 pointed out, slog did not properly handle empty groups.
https://go.dev/cl/508436 dealt with most cases inside slog itself,
but handlers must still do a check on their own. Namely, a handler
must not output a group created by WithGroup unless the Record
has attributes.
This change adds a test to slogtest to check that case.
Fixes #61227.

Also fix a (minor) double-Close error in Serve that was exposed by the
test fix.
Serve accepts a net.Listener, which produces net.Conn instances.
The documentation for net.Conn requires its methods to be safe for
concurrent use, so most implementations likely allow Close to be
called multiple times as a side effect of making it safe to call
concurrently with other methods. However, the net.Conn interface is a
superset of the io.Closer interface, io.Closer explicitly leaves the
behavior of multiple Close calls undefined, and net.Conn does not
explicitly document a stricter requirement.
Perhaps more importantly, the test for the fcgi package calls
unexported functions that accept an io.ReadWriteCloser (not a
net.Conn), and at least one of the test-helper ReadWriteCloser
implementations expects Close to be called only once.
The goroutine leaks were exposed by a racy arbitrary timeout reported
in #61271. Fixing the goroutine leak exposed the double-Close error:
one of the leaked goroutines was blocked on reading from an unclosed
pipe. Closing the pipe (to unblock the goroutine) triggered the second
Close call.
Fixes #61271.

We cancel the Context to unblock the test as soon as all of the "exit"
processes have completed. If that happens to occur before all of the

ignore them.

The previous upper bound was around 0.375 s, which is empirically
too short on a slow, heavily-loaded builder. Since the test doesn't
seem to depend on the actual duration in any meaningful way, let's
make it several orders of magnitude larger.

When adding MPTCP support to address the proposal #56539, I missed the
GODEBUG setting from Russ Cox's plan:
I am inclined to say that we add MPTCP as an opt-in for a release or
two, and then make it opt-out. There should be a GODEBUG setting (...)
See: https://github.com/golang/go/issues/56539#issuecomment-1309294637
Thanks to andrius4669 for having reported this issue to me.
It makes sense to have this GODEBUG setting not to have to modify
applications to use MPTCP (if available). It can then be useful to
estimate the impact in case we want to switch from opt-in to opt-out
later.
The MPTCP E2E test has been modified to make sure we can enable MPTCP
either via the source code like it was already the case before or with
this environment variable:
GODEBUG=multipathtcp=1
The documentation has been adapted accordingly.
I don't know if it is too late for Go 1.21 but I had to put a version in
the documentation. The modification is small, the risk seems low and
this was supposed to be there from the beginning according to Russ Cox's
specifications. It can also be backported or only be present in the
future v1.22 if it is easier.
Note: I didn't re-open #56539 or open a new one. It is not clear to me
what I should do in this case.
Fixes #56539

atomic
In CL 421441, we changed syscall to allow concurrent calls to
forkExec.
On platforms that support the pipe2 syscall that is the right
behavior, because pipe2 atomically opens the pipe with CLOEXEC already
set.
However, on platforms that do not support pipe2 (currently aix and
darwin), syscall.forkExecPipe is not atomic, and the pipes do not
initially have CLOEXEC set. If two calls to forkExec proceed
concurrently, a pipe intended for one child process can be
accidentally inherited by the other. If the process is long-lived, the
pipe can be held open unexpectedly and prevent the parent process from
reaching EOF reading the child's status from the pipe.

GetFileInformationByHandleEx can return `ERROR_FILE_NOT_FOUND` when no
files were found in a root directory, as per MS-FSA 2.1.5.6.3 [1].
This error code should not be treated as an error, but rather as an
indication that no files were found, in which case `readdir` should
return an empty slice.
This CL doesn't add any test as it is difficult to trigger this error
code. Empty root directories created using Windows utilities such as
`net use` always report at least the optional `.` and `..` entries.
A reproducer is provided in #61159, but it requires WinFSP to be
installed.
Fixes #61159

CL 507975 resulted in new data races (as reported in #61212), because
the pkg argument to NewChecker was mutated.
Fix this by deferring the recording of the goVersion in pkg until type
checking is actually initiated via a call to Checker.Files.
Additionally, modify types2/check.go to bring it in sync with the
changes in go/types/check.go, and generate the new version_test.go from
the types2 file.
Also move parsing the version into checkFiles, for simplicity.

Handlers should not display empty groups.
A group with no attributes is certainly empty. But we also want to
consider a group to be empty if all its attributes are empty groups.
The built-in handlers did not handle this second case properly.
This CL fixes that.
There are two places in the implementation that we need to consider.
For Values of KindGroup, we change the GroupValue constructor to omit
Attrs that are empty groups. A Group is then empty if and only if it
has no Attrs. This avoids a recursive check for emptiness.
It does require allocation, but that doesn't worry us because Group
values should be relatively rare.
For groups established by WithGroup, we avoid opening such groups
unless the Record contains non-empty groups. As we did for values, we
avoid adding empty groups to records in the first place, so we only
need to check that the record has at least one Attr.
We are doing extra work, so we need to make sure we aren't slowing
things down unduly. Benchmarks before and after this change show
minimal differences.
Fixes #61067.

When building programs to GOOS=wasip1, the program does not have the
guarantees that the underlying directories will come from a file system
where a zero inode value indicates that the entry was deleted but not
yet removed from the directory. The host runtime may be running on
windows or may be exposing virtual user-space file systems that do not
have the concept of inodes. In those setup, we assume that the host
runtime is in charge of dealing with edge cases such as skipping
directory entries with zero inodes when needed, and the guest
application should trust the list of entries that it sees;
therefore, we disable skipping over zero inodes on wasip1.

Clients of go/types, such as analyzers, may need to know which
specific Go version a package is written for. Record that information
in the Package and expose it using the new GoVersion method.
Update parseGoVersion to handle the new Go versions that may
be passed around starting in Go 1.21.0: versions like "go1.21.0"
and "go1.21rc2". This is not strictly necessary today, but it adds some
valuable future-proofing.
While we are here, change NewChecker from panicking on invalid
version to saving an error for returning later from Files.
Go versions are now likely to be coming from a variety of sources,
not just hard-coded in calls to NewChecker, making a panic
inappropriate.

However our implement of SSA convert FMADD -x,y,z to FNMADD x,y,z which

CL 497675 modified Rows such that context errors are propagated through
Rows.Err(). This caused an issue where calling Close meant that an
internal cancellation error would (eventually) be returned from Err:
1. A caller makes a query using a cancellable context.
2. initContextClose sees that either the query context or the
transaction context can be canceled, so will need to spawn a
goroutine to capture their errors.
3. initContextClose derives a context from the query context via
WithCancel and sets rs.cancel.
4. When a user calls Close, rs.cancel is called. awaitDone's ctx is
cancelled, which is good, since we don't want it to hang forever.
5. This internal cancellation (after CL 497675) has its error saved on
contextDone.
6. Later, calling Err will return the error in contextDone if present.
This leads to a race condition depending on how quickly Err is called
after Close.
The docs for Close and Err state that calling Close should have no
affect on the return result for Err. So, a potential fix is to ensure
that awaitDone does not save the error when the cancellation comes from
a Close via rs.cancel.
This CL does that, using a new context not derived from the query
context, whose error is ignored as the query context's error used to be
before the original bugfix.
The included test fails before the CL, and passes afterward.
