5c14d72191 encoding/prototext: use testmessages_test.go approach, too
With this change, we establish a similar mechanism in encoding/prototext as
already exists in the proto package: a testmessages_test.go which serves as an
extension point where one can inject more variants into the corpus of test
messages.

f01a588e58 encoding/protojson, internal/encoding/json: handle missing object values
In internal/encoding/json, report an error when encountering a }
when we are expecting an object field value. For example, the input
`{"":}` now correctly results in an error at the closing } token.

In encoding/protojson, check for an unexpected EOF token in
skipJSONValue. This is redundant with the check in internal/encoding/json,
but adds a bit more defense against any other similar bugs that
might exist.

bfcd6476a3 protojson: configurable recursion limit when unmarshalling
Fixes golang/protobuf#1583 and golang/protobuf#1584

Limits the level of recursion when parsing JSON to avoid
fatal stack overflow errors if input uses pathologically
deep nesting. This is already a feature of the binary
format, and this adds that feature to the JSON format.

This also re-implements how JSON values are discarded
to be more efficient (and not use recursion).

f930b1dc76 encoding/protojson: fix parsing of google.protobuf.Timestamp
The Timestamp message uses a subset of RFC 3339.
RFC 3339, section 5.6 specifies that the subsecond field can have
any non-zero number of digits.
On the other hand, the protobuf documentation specifies that Timestamp
uses RFC 3339 with a few restrictions. In other words,
protobuf does NOT use RFC 3339, but rather a subset of it.

An upstream change https://go.dev/cl/425037 modifies the time package
to be internally consistent about handling of extra subsecond digits
allowing it to be more in line with RFC 3339.

Make a corresponding change here to ensure we remain compliant
with protobuf's restricted use of RFC 3339.

3) strips the "message_set_extension" for well-formed extensions

We make similar adjustments to the JSONName accessor so that it applies

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.

c4051cd4ec types/known: remove packages present in genproto
Remove the generated proto packages that already exist in
google.golang.org/genproto. We want to eventually move these
packages here, but it doesn't need to happen yet.

Add a local copy of fieldmaskpb for use in tests.

Refactor proto generation to override import paths using the
M<source>=<import_path> compiler option instead of by patching the
source files.

d2ece139c6 encoding/protojson: refactor to follow prototext pattern
All unmarshaling error messages now contain line number and column
information, except for the following errors:
- `unexpected EOF`
- `no support for proto1 MessageSets`
- `required fields X not set`

Changes to internal/encoding/json:
- Moved encoding funcs in string.go and number.go into encode.go.
- Separated out encoding kind constants from decoding ones.
- Renamed file string.go to decode_string.go.
- Renamed file number.go to decode_number.go.
- Renamed Type struct to Kind.
- Renamed Value struct to Token.
- Token accessor methods no longer return error.
  Name, Bool, ParsedString will panic if called on the wrong kind.
  Float, Int, Uint has ok bool result to check against.
- Changed Peek to return Token and error.

Changes to encoding/protojson:
- Updated internal/encoding/json API calls.
- Added line info on most unmarshaling error messages and kept
  description simple and consistent.

74b1460c5b encoding: add Format helper function and method
The Format function and MarshalOptions.Format method are helper
functions for directly obtaining the formatted string for a message
without having to deal with errors or convert a []byte to string.
It is only intended for human consumption (e.g., debugging or logging).

We also add a MarshalOptions.Multiline option to specify that the output
should use some default indentation in a multiline output.

This assists in the v1 to v2 migration where:
	protoV1.CompactTextString(m) => prototext.MarshalOptions{}.Format(m)
	protoV1.MarshalTextString(m) => prototext.Format(m)

At Google, there are approximately 10x more usages of MarshalTextString than
CompactTextString, so it makes sense that the top-level Format function
does multiline expansion by default.

Fixes #850

fc5f8c340a encoding: optimize for oneofs
Suppose a oneof has N fields, the previous marshaling logic
would traverse every field checking for presence. This is O(N).
Using the protoreflect.Message.WhichOneof method, we can reduce
this to O(1). This optimization is exceptionally useful for oneofs
with a large number of fields.
