Eric Salo	40998462d6	add upb_MtDataEncoder_EncodeExtension() We need to sharpen the distinction between messages and extensions in the mini descriptor encoder, so split the code paths for each. PiperOrigin-RevId: 480675339	2 years ago
Joshua Haberman	b33fd88ed3	Added function for getting the type of a MiniTable field Prior to this CL, users were relying on `field->descriptortype` to get the field type. This almost works, as `field->descriptortype` is almost, but not quite, the field type of the field. In two special cases we deviate from the true field type, for ease of parsing and serialization: - For open enums, we use `kUpb_FieldType_Int32` instead of `kUpb_FieldType_Enum`, because from the perspective of the wire format, an open enum field is equivalent to int32. - For proto2 strings, we use `kUpb_FieldType_Bytes` instead of `kUpb_FieldType_String`, because proto2 strings do not perform UTF-8 validation, which makes them equivalent to bytes. In this CL we add a public API function: ``` // Returns the true field type for this field. upb_FieldType upb_MiniTableField_Type(const upb_MiniTable_Field* f); ``` This will provide the actual field type for this field. Note that this CL changes the MiniDescriptor format. Previously MiniDescriptors did not contain enough information to distinguish between Enum/Int32. To remedy this we added a new encoded field type, `kUpb_EncodedType_ClosedEnum`. PiperOrigin-RevId: 479387672	2 years ago
Joshua Haberman	d5bd55cde1	Treat unlinked sub-messages in the MiniTable as unknown This is an observable behavior change in the decoder. After submitting this CL, clients of the decoder can assume that any unlinked sub-messages will be treated as unknown, rather than crashing. Unlinked sub-messages must never have values present in the message. We can verify this with asserts. Since the values are never set, the encoder should never encounter data for any unlinked sub-message. ``` name old cpu/op new cpu/op delta BM_ArenaOneAlloc 18.3ns ± 9% 17.9ns ± 2% ~ (p=0.690 n=5+5)

Joshua Haberman	896e74c141	Optimizes `upb_MiniTable_Enum` for large but dense enums. Optimizes `upb_MiniTable_Enum` for enums with many values (>64) but with relatively dense packing in numeric space. This CL optimizes both the size and speed of such enums: - size: 30x code size reduction - speed: moved from linear search to a constant-time bit test Negative enum values are still expensive, as they are never put into the bitfield.

Joshua Haberman	fa8b605f78	Implemented MiniDescriptors for proto2 enums. An enum MiniDescriptor simply encodes a set of valid `int32_t` values, so that the protobuf parser can test whether a given enum value is known or not. The format implemented here is novel and needs to be documented. In short, the format is: 1. base92 values 0-31: 5-bit mask indicating presence or absence of the next five enum values. 2. base92 values 60-91: varint indicating skip over a region of enum values. Negative enum values are encoded as their `uint32_t` equivalent. PiperOrigin-RevId: 442892799	3 years ago
