-buildmode=shared installs shared libraries into GOROOT
and expects to reuse them across builds.
Builds in module mode, however, each have their own set of
dependencies (determined by the module's requirements), so in general
cannot share dependencies with a single GOROOT.
Ideally in the long term we would like to eliminate -buildmode=shared
entirely (see #47788), but first we need a replacement for the subset
of use-cases where it still works today.
In the meantime, we should run these tests only in GOPATH mode.

timerModifiedEarliest contains the lowest possible expiration for a
modified earlier timer, which may be earlier than timer0When because we
haven't yet updated the heap. Note "may", as the modified earlier timer
that set timerModifiedEarliest may have since been modified later or
deleted.
We can clear timerModifiedEarliest when the last timer is deleted
because by definition there must not be any modified earlier timers.
Why does this matter? checkTimersNoP claims that there is work to do if
timerModifiedEarliest has passed, causing findRunnable to loop back
around to checkTimers. But the code to clean up timerModifiedEarliest in
checkTimers (i.e., the call to adjusttimers) is conditional behind a
check that len(pp.timers) > 0.
Without clearing timerModifiedEarliest, a spinning M that would
otherwise go to sleep will busy loop in findRunnable until some other
work is available.
Note that changing the condition on the call to adjusttimers would also
be a valid fix. I took this approach because it feels a bit cleaner to
clean up timerModifiedEarliest as soon as it is known to be irrelevant.

fsys.Walk is cloned from filepath.Walk, which has always handled
a walk of a directory by reading the full directory before calling the
callback on the directory itself. So if the callback returns fs.SkipDir,
those entries are thrown away, but the expense of reading them was
still incurred. (Worse, this is the expensive directory read that also
calls Stat on every entry.) On machines with slow file system I/O,
these reads are particularly annoying. For example, if I do
go list m...
there is a call to filepath.Walk that is told about $GOROOT/src/archive
and responds by returning filepath.SkipDir because archive does not
start with m, but it only gets the chance to do that after the archive
directory has been read. (Same for all the other top-level directories.)
Even something like go list github.com/foo/bar/... reads every top-level
$GOPATH/src directory.
When we designed filepath.WalkDir, one of the changes we made was
to allow calling the callback twice for a directory: once before reading it,
and then possibly again if the read produces an error (uncommon).
This CL changes fsys.Walk to use that same model. None of the callbacks
need changing, but now the $GOROOT/src/archive and other top-level
directories won't be read when evaluating a pattern like 'm...'.

If a goroutine is started within a user region, internal/trace assigns
the child goroutine a nameless region for its entire lifetime which is
assosciated the same task as the parent's region.
This is not strictly necessary: a child goroutine is not necessarily
related to the task unless it performs some task operation (in which
case it will be associated with the task through the standard means).
However, it can be quite handy to see child goroutines within a region,
which may be child worker goroutines that you simply didn't perform task
operations on.
If the first GC occurs during a region, the GC worker goroutines will
also inherit a child region. We know for sure that these aren't related
to the task, so filter them out from the region list.
Note that we can't exclude system goroutines from setting activeRegions
in EvGoCreate handling, because we don't know the goroutine start
function name until the first EvGoStart.

For a large module, opening the index was populating tables with
entries for every package in the module. If we are only using a small
number of those packages, this is wasted work that can dwarf the
benefit from the index.
This CL changes the index reader to avoid loading all packages
at module index open time. It also refactors the code somewhat
for clarity.
It also removes some duplication by defining that a per-package
index is a per-module index containing a single package, rather
than having two different formats and two different decoders.
It also changes the string table to use uvarint-prefixed data
instead of having to scan for a NUL byte. This makes random access
to long strings more efficient - O(1) instead of O(n) - and can significantly
speed up the strings.Compare operation in the binary search looking
for a given package.
Also add a direct test of the indexing code.

load.loadPackageData was only using an index for modules,
not for standard library packages. Other parts of the code were
using the index, so there was some benefit, but not as much
as you'd hope.
With the index disabled, the Script/work test takes 2.2s on my Mac.
With the index enabled before this CL, it took 2.0s.
With the index enabled after this CL, it takes 1.6s.
Before this CL, the Script/work test issued:
429 IsDir
19 IsDirWithGoFiles
7 Lstat
9072 Open
993 ReadDir
256 Stat
7 Walk
3 indexModule
24 openIndexModule
525 openIndexPackage
After this CL, it issued:
19 IsDirWithGoFiles
7 Lstat
60 Open
606 ReadDir
256 Stat
7 Walk
3 indexModule
24 openIndexModule
525 openIndexPackage
This speedup helps the Dragonfly builder, which has very slow
file I/O and is timing out since a recent indexing change.
Times for go test -run=Script/^work$ on the Dragonfly builder:
50s before indexing changes
31s full module indexing of std
46s per-package indexing of std
It cuts the time for go test -run=Script/^work$ from 44s to 20s.
For #53577.

Additional header to remove if set before calling http.ServeContent.
The API of ServeContent is that one should set Content-Encoding before calling it, if the content is encoded (e.g., compressed). But then, if content has not been modified, that header should be removed, according to RFC 7232 section 4.1.

Set a reasonable starting line number before processing the body of
the function in the order pass.
We update base.Pos each time we process a node, but some of the
libfuzzer instrumentation is added before we process any node, so the
base.Pos used is junk.

Also simplify platform-dependent handling of the PATH variable,

Avoid race conditions when a new connection is accepted just after
Server.Close or Server.Shutdown is called by waiting for the
listener goroutines to exit before proceeding to clean up active
connections.
No test because the mechanism required to trigger the race condition
reliably requires such tight coupling to the Server internals that
any test would be quite fragile in the face of reasonable refactorings.

CL 377516 made it so that memory metrics are truly monotonic, but also
updated how heapLive tracked allocated memory to also be monotonic.
The result is that cached spans with allocated memory aren't fully
accounted for by the GC, causing it to make a worse assumption (the
exact mechanism is at this time unknown), resulting in a memory
regression, especially for smaller heaps.
This change is a partial revert of CL 377516 that makes heapLive a
non-monotonic overestimate again, which appears to resolve the
regression.
For #53738.
