98873a2050 internal/impl: pass ExtensionTypeDescriptor to extensionMap
The layers freely convert between ExtensionTypeDescriptor (via
ExtensionTypeDescriptor.Type) and ExtensionType (via
ExtensionType.TypeDescriptor()). For certain hot functions , like
(*extensionMap).Has() and (*extensionMap).Get(), this saves a Type() and
TypeDescriptor() pair.

Oddly, the gains are bigger than I expected. This commit is
02-typedesciptor-not-type, it is layered on top of CL 576315
(named 01-cse-hasextension):

8a744307e3 internal/cmd/generate-types: manual CSE of m.messageInfo()
messageInfo() looks like this:

    func (ms *messageState) messageInfo() *MessageInfo {
    	mi := ms.LoadMessageInfo()
    	if mi == nil {
    		panic("invalid nil message info; this suggests memory corruption due to a race or shallow copy on the message struct")
    	}
    	return mi
    }

    func (ms *messageState) LoadMessageInfo() *MessageInfo {
    	return (*MessageInfo)(atomic.LoadPointer((*unsafe.Pointer)(unsafe.Pointer(&ms.atomicMessageInfo))))
    }

Which is an atomic load and a predictable branch. On x86, this 64-bit
load is just a MOV. On other platforms, like ARM64, there's actual
atomics involved (LDAR).

Meaning, it's cheap, but not free. Eliminate redundant copies of this
(Common Subexpression Elimination).

The newly added benchmarks improve by (geomean) 2.5%:

reduced atomics.

7259b46773 all: implement proto2/proto3 as editions [1/2]
This change removes most usages of Syntax() from the repository and uses
edition features for instead. The appropriate edition feature defaults are
loaded for proto2/proto3 when the initialization of the descriptors
start.

All of these changes were tested on the Google corpus.

UnmarshalJSON method should be generated for enums. This change only

2b71f26c99 all: fix go generate (needs protolegacy build tag for weak fields)
Prior to this change, one could either use go generate or
./test.bash -regenerate to re-generate the files — but only
the latter way would work.

With this change, we make ./test.bash -regenerate call go generate
so that the two ways cannot diverge again.

This improves wall time and allocated memory. I haven't found any
case (0 values, few values, many values) where this change is a
consistent regression. For fields with thousands of values, this
reduces memory usage by 50% and wall time by 20%.

bc1253ad37 types/descriptorpb: regenerate using latest protobuf v22.0 release
This updates all generated code to match the contents of the latest
v22.0 release of Protobuf.

This involved a couple of changes to the script that does the sync'ing:
  1. The new Protobuf version no longer includes autoconf configuration
     and instead requires using bazel to build things.
  2. The new Protobuf release does not have an artifact named
     "protobuf-all-${VERSION}.tar.gz", but the one named
     "protobuf-${VERSION}.tar.gz" has all of the sources and was
     sufficient for the regenerate.bash script to complete.

This change does NOT regenerate the protos related to benchmarks.
The Protobuf repo no longer includes benchmarks. The CL removing them
says they are superceded by google/fleetbench:
    83c499de86
But that project's proto benchmark files are very different:
    https://github.com/google/fleetbench/tree/main/fleetbench/proto
So I commented out those steps in the generation code since the benchmarks
will need some work to reconcile with fleetbench.

This code adds known failing tests for conformance. New test cases were
added in https://github.com/protocolbuffers/protobuf/pull/9534, but the
Go protojson package does not behave according to the new tests. There
is an existing issue in GitHub about this:

fb30439f55 testing/protopack: add Message.UnmarshalAbductive
The protobuf wire format is insufficiently self-decribing such that
it is impossible to know whether for sure whether an unknown bytes value
is a sub-message or not. However, protopack is primarily used for debugging
where a best-effort guess is still very useful.

The Message.UnmarshalAbductive unmarshals an unknown bytes value as a message

d347099942 internal/cmd/generate-types: use ConsumeBytes instead of ConsumeString
The protowire.{ConsumeBytes,ConsumeString} funcs are identical except
that the latter allocates a string by implicitly converting the []byte.
Avoid using ConsumeString since we can do the conversion ourselves
at a latter point and sometimes avoid the allocation.

b5523e32b3 all: return less-specific, but more informative wire unmarshal errors
When proto.Unmarshal fails, it is almost always due to being passed
input which is not a wire-format message. (A text-format message, a
message with framing left intact, and so forth.) An error like
"variable length integer overflow" can be confusing in this case, since
it implies the problem is the varint rather than the input being
entirely wrong.

Replace all Unmarshal parse errors with "cannot parse invalid
wire-format data".

e14d6b3cdc reflect/protoreflect: add FieldDescriptor.TextName
Add a new TextName accessor that returns the field name that should
be used for the text format. It is usually just the field name, except:
1) it uses the inlined message name for groups,
2) uses the full name surrounded by brackets for extensions, and
3) strips the "message_set_extension" for well-formed extensions
to the proto1 MessageSet.

We make similar adjustments to the JSONName accessor so that it applies
similar semantics for extensions.

The two changes simplifies all logic that wants the humanly readable
name for a field.

81db48ad09 all: move well-known types
This is step 2 of 6 in a multi-stage migration
to move the well-known types
from the google.golang.org/genproto module
to the google.golang.org/protobuf module.

The generated Go packages for field_mask.proto, api.proto,
type.proto, and source_context.proto are being moved over
to this module alongside all the other well-known types.

In order to move these types between two modules,
there needs to be a sequence of changes submitted in
decently rapid succession. It is impossible to atomically
make these changes, so a brief breakage is inevitable.
The steps are as follows:

Step 1: Submit a change to cloud.google.com/go/internal/gapicgen
to avoid generating the well-known types. Otherwise, the tool
will undo the changes made in step 3.
See https://code-review.googlesource.com/c/gocloud/+/56810

Step 2: Submit a change to google.golang.org/protobuf that
adds the generated well-known types being migrated to that module.
In order to prevent the situation where a user links in
too old a version of the genproto module such that
duplicate registration occurs for the well-known types,
the registry is specially modified to provide an error
message that instructs users to upgrade the genproto module.
See https://golang.org/cl/234937

Step 3: Submit a change to google.golang.org/genproto that
switches all generated well-known types to be aliases to the
ones declared in google.golang.org/protobuf from the previous step.
This will cause the genproto module to incur an dependency
on an unreleased version of the protobuf module.
See https://github.com/googleapis/go-genproto/pull/372

Step 4: Submit a change to google.golang.org/protobuf that
adds a weak module depdency on the genproto module at the
revision from the previous step.

Step 5: Release google.golang.org/protobuf@v1.24.0.

Step 6: Submit a change to google.golang.org/genproto that
updates the protobuf module dependency to v1.24.0.

118baf6390 all: funnel similar functionality through a single function
Some companies (e.g., Google) run a profiling service where they may
choose to special-case certain symbols in a binary to classify
commonly used libraries like protobufs.

This CL funnels similar functionality through a single function
so that they can be more easily identified. This is by no means a
firm statement that these identifiers will never change names,
but at least the code documents warnings to avoid changing the
name of certain identifiers.

This CL provides the following semi-stable symbol names:
	"google.golang.org/protobuf/proto".MarshalOptions.size
	"google.golang.org/protobuf/proto".MarshalOptions.marshal
	"google.golang.org/protobuf/proto".UnmarshalOptions.unmarshal
	"google.golang.org/protobuf/encoding/prototext".MarshalOptions.marshal
	"google.golang.org/protobuf/encoding/prototext".UnmarshalOptions.unmarshal
	"google.golang.org/protobuf/encoding/protojson".MarshalOptions.marshal
	"google.golang.org/protobuf/encoding/protojson".UnmarshalOptions.unmarshal

Merge and Clone are not part of the above set since there is a
possibility that MergeOptions will be added in the future.

We use an unexported method so that we have the freedom to change the
method however we want since profilers do not care about that.

f0831e87e2 internal/impl: change unmarshal func return to unmarshalOptions
The fast-path unmarshal funcs return the number of bytes consumed.

Change these functions to return an unmarshalOutput struct instead, to
make it easier to add to the results. This is groundwork for allowing
the fast-path unmarshaler to indicate when the unmarshaled message is
known to be initialized.

94e730bc38 internal/testprotos: hide all public testprotos
The encoding/testprotos and reflect/protoregistry/testprotos are
accessible by other modules. Move them under internal/testprotos
to dissuade programmers who are too lazy to use their own test protos
when they need one.
