The current implementation of the http package strips double quotes
from the cookie-value during parsing, resulting in the serialized
cookie not including them. This patch addresses this limitation by
introducing a new field to track whether the original value was
enclosed in quotes.
Additionally, the internal representation of a cookie in the cookiejar
package has been adjusted to align with the new representation.
The syntax of cookies is outlined in RFC 6265 Section 4.1.1:

This change adds a concurrent hash-trie map implementation to the
standard library in the new internal/concurrent package, intended to
hold concurrent data structures. (The name comes from how Java names
their concurrent data structure library in the standard library.)
This data structure is created specially for the upcoming unique
package. It is built specifically around frequent successful lookups and
comparatively rare insertions and deletions.
A valid question is whether this is worth it over a simple locked map.
Some microbenchmarks in this new package show that yes, this extra
complexity appears to be worth it.
Single-threaded performance for LoadOrStore is comparable to a locked
map for a map with 128k small string elements. The map scales perfectly
up to 24 cores for Loads, which is the maximum available parallelism
on my machine. LoadOrStore operations scale less well. Small maps will
have a high degree of contention, but for the unique library, small maps
are very unlikely to stay small if there are a lot of inserts, since
they have a full GC cycle to grow.
For #62483.

This test attempted to be clever by looking for the entirety of $GOCACHE
in the compile command line to ensure that the profile was coming from
cache.
Unfortunately, on Windows $GOCACHE contains \, which needs extra
escaping in a regexp. As an approximate alternative, just look for the
"gocache" component specified when defining GOCACHE.
This fixes the Windows longtest builders.

This patch revises the algorithm/strategy used for overlapping the
stack slots of disjointly accessed local variables. The main change
here is to allow merging the stack slot of B into the slot for A if
B's size is less then A (prior to this they had to be identical), and
to also allow merging a non-pointer variables into pointer-variable
slots.
The new algorithm sorts the candidate list first by pointerness
(pointer variables first), then by alignment, then by size, and
finally by name. We no longer check that two variables have the same
GC shape before merging: since it should never be the case that we
have two vars X and Y both live across a given callsite where X and Y
share a stack slot, their gc shape doesn't matter.
Doing things this new way increases the total number of bytes saved
(across all functions) from 91256 to 124336 for the sweet benchmarks.

Import declaration matching currently has a list of specific cases. It
allows bare imports, dot imports, and renamed imports named "exec" and
"rtabi".
Keeping a specific allowlist of renamed imports is unnecessary and
causes annoyance for developers adding such imports, as the bootstrap
build errors do not make it clear that this is where the issue lies.
We can simplify this to be much more general. The body of the condition
will still only rewrite imports in cmd/ or in bootstrapDirs.
I believe the only downside of this change is that it makes it a bit
more likely to match and replace within comments. That said, there
should be no harm in replacements within comments.
This change results in no change to the resulting bootstrap source tree:

This is the final CL in the series adding PGO preprocessing support to
cmd/go. Now that the tool is hooked up, we integrate with the build
cache to cache the result.
This is fairly straightforward. One difference is that the compile and
link do caching through updateBuildID. However, preprocessed PGO files
don't have a build ID, so it doesn't make much sense to hack our way
through that function when it is simple to just add to the cache
ourselves.
As as aside, we could add a build ID to the preproccessed file format,
though it is not clear if it is worthwhile. The one place a build ID
could be used is in buildActionID, which currently compute the file hash
of the preprocessed profile. With a build ID it could simply read the
build ID. This would save one complete read of the file per build
(cmd/go caches the hash), but each compile process also reads the entire
file, so this is a small change overall.
Fixes#58102.

The new go tool preprofile preprocesses a PGO pprof profile into an
intermediate representation that is more efficient for the compiler to
consume. Performing preprocessing avoids having every single compile
process from duplicating the same processing.
This CL prepares the initial plumbing to support automatic preprocessing
by cmd/go.
Each compile action takes a new dependency on a new "preprocess PGO
profile" action. The same action instance is shared by all compile
actions (assuming they have the same input profile), so the action only
executes once.
Builder.build retrieves the file to pass to -pgofile from the output of
the preprocessing action, rather than directly from
p.Internal.PGOProfile.
Builder.buildActionID also uses the preprocess output as the PGO
component of the cache key, rather than the original source. This
doesn't matter for normal toolchain releases, as the two files are
semantically equivalent, but it is useful for correct cache invalidation
in development. For example, if _only_ go tool preprofile changes
(potentially changing the output), then we must regenerate the output
and then rebuild all packages.
This CL does not actually invoke go tool preprocess. That will come in
the next CL. For now, it just copies the input pprof profile.
This CL shouldn't be submitted on its own, only with the children. Since
the new action doesn't yet use the build cache, every build (even fully
cached builds) unconditionally run the PGO action.

times out or is canceled before a Dial completes, the Dial is
canceled.
Change this so that the lifetime of a Dial call is not bound
by the request that originated it.
This change avoids a scenario where a Transport can start and
then cancel many Dial calls in rapid succession:
- Request starts a Dial.
- A previous request completes, making its connection available.
- The new request uses the now-idle connection, and completes.
- The request Context is canceled, and the Dial is aborted.

The SSA rewrite pass has some logic that looks to see whether a
suspiciously large number of rewrites is happening, and if so, turns
on logic to try to detect rewrite cycles. The cycle detection logic is
quite expensive (hashes the entire function), meaning that for very
large functions we might get a successful compilation in a minute or
two with no cycle detection, but take a couple of hours once cycle
detection kicks in.

partially based on the size of the function (meaning that we'll wait

After the alignment of the loop header is performed, the offset of the checked
conditional branch instruction may overflow, so it needs to be checked again.
When checking whether the offset of the branch jump instruction overflows, it
can be classified and processed according to the range of the immediate field
of the specific instruction, which can reduce the introduction of unnecessary
jump instructions.

which make sense as WriterTo, but for ReaderFrom it makes more sense
thinking of rf instead of rt.
