Protobuf Team Bot	ae583df89a	Fix upb_proto_aspect to correctly reexport providers. PiperOrigin-RevId: 545448300	1 year ago
Protobuf Team Bot	3ecb7a4163	Make `upb_proto_aspect` reexport all `deps` when `srcs` is empty. This special `proto_library` behavior is known as an alias library: https://bazel.build/reference/be/protocol-buffer#proto_library_args Without this CL, the compilation of the added test fails with: ``` test_import_empty_srcs.upb.c:12:10: error: module :test_import_empty_srcs_proto.upb does not depend on a module exporting 'test.upb.h' ``` PiperOrigin-RevId: 545153380	1 year ago

Joshua Haberman	07f6b578ee	Split mini_descriptor into its own directory After this change, `mini_table` only has MiniTable definitions themselves. Everything having to do with the MiniDescriptor wire format is in `mini_descriptor`. Also rearranged some of the files in mini_table to have better structure for `internal/`.

Protobuf Team Bot	532b4d0671	Fix `upb_MiniTableField_CType()` to work correctly for enums & strings. `upb_MiniTableField_CType()` was directly checking the `descriptortype` in `upb_MiniTableField`, without taking `field->mode` into account -- which can indicate that an int32 is actually an enum, or that bytes is really a string.

Joshua Haberman	a0f520dc75	Added a new dynamic tree shaking model to upb, with the intention of removing the old model once YouTube has migrated. The `kUpb_DecodeOption_ExperimentalAllowUnlinked` flag to the decoder will enable the new behavior. When that flag is not passed, tree shaking with the old model will still be possible. "Dynamic tree shaking" in upb is a feature that allows messages to be parsed even if the MiniTables have not been fully linked. Unlinked sub-message fields can be parsed by preserving their data in the unknown fields. If the application later discovers that the message field is actually needed, the MiniTable can be patched to properly link that field, and existing message instances can "promote" the data from the unknown fields to an actual message of the correct type. Before this change, dynamic tree shaking stored unparsed message data in the unknown fields of the parent. In effect, we were treating the field as if it did not exist at all. This meant that parsing an unlinked field did not affect the hasbits or oneof cases of the parent, nor did it create a `upb_Array` or `upb_Map` for array/map fields. Only when a message was linked and promoted did any of these things occur. While this model had some amount of conceptual simplicity, it caused significant problems with oneofs. When multiple fields inside a single oneof are parsed from the wire, order matters, because later oneof fields must overwrite earlier ones. Dynamic tree shaking can mean that some fields in a oneof are linked while others are not. It is essential that we preserve this ordering semantic even when dynamic tree shaking is being used, but it is difficult to do if the oneof's data can be split between linked fields (which have been reified into parsed field data) and unlinked fields (whose data lives in the unknown fields of the parent). To solve this problem, this CL changes the representation for unlinked fields. Instead of being placed in the parent's unknown fields, we create an actual message instance for each unlinked message we parse, but we use a placeholder "empty message" MiniTable as the message's type. All of the message's data will therefore be placed into the "empty message's" unknown fields. But unlike before, this "empty message" is actually present according to the hasbits, oneof case, and `upb_Array`/`upb_Map` of the parent. This means that all of the oneof presence logic works as normal. Since the MiniTable can be patched at any time, we need a bit in the message instance itself to signal whether a pointer to a sub-message is an "empty message" or not. When dynamic tree shaking is in use, all users must be capable of recognizing an empty message and acting accordingly (promoting, etc) even if the MiniTable itself says that the field is linked. Because dynamic tree shaking imposes this extra requirement on users, we require that users pass an extra option to the decoder to allow parsing of unlinked sub-messages. Many existing users of upb (Ruby, PHP, Python, etc) will always have fully-linked MiniTables, so there is no reason for them to add extra logic to handle empty messages. By omitting the `kUpb_DecodeOption_ExperimentalAllowUnlinked` option, they will be relieved of the duty to check the tagged pointer that would indicate an empty, unlinked message. For existing users of dynamic tree shaking, there are three main changes: 1. The APIs in message/promote.h have changed, and users will need to update to the new interfaces. 2. The model for maps has changed slightly. Before, we required that map entries always had their values linked; for dynamic tree shaking to apply to maps, we required that the entry was left unlinked, not the entry's value. In the new model, that is reversed: map entries must always be linked, but a map entry's value can be unlinked. 3. The presence model for unlinked fields has changed. Unlinked fields will now register as "present" from the perspective of hasbits, oneof cases, and array/map entries. Users must test the tagged pointer to know if a message is of the correct, linked type or whether it is a placeholder "empty" message. There is a new function `upb_Message_GetTaggedMessagePtr()`, as well as a new accessor `upb_MessageValue.tagged_msg_val` that can be used to read and test the tagged pointer directly.

Joshua Haberman	14bad4a5bf	Fixed a bug in `upb_Map_Delete()` that caused crashes in map.delete(k) for Ruby when string-keyed maps were in use. Fixes: https://github.com/protocolbuffers/protobuf/issues/12580 When `upb_Map_Delete(map, k, &v)` was called for a string-keyed map, the returned value `v` contained garbage data instead of the true string length. Since `map.delete(k)` in Ruby returns the deleted value, this was causing a garbage length to be used when allocating and copying data. PiperOrigin-RevId: 535261609	2 years ago

Joshua Haberman	18b98a8ec1	Give sub-messages and sub-enums distinct initialization code paths. Prior to this change, all sub-messages and sub-enums were initialized to NULL. Going forward, sub-messages will need to be initialized differently than sub-enums. To facilitate this, we change the order of subs, so that sub-messages always come before sub-enums. Then when we allocate the subs, we can initialize them in two separate loops. This unfortunately requires one extra iteration over the fields if any closed enums are present, to adjust the `submsg_index` according to how many sub-messages were seen. This CL is the first step towards changing how we handle unlinked sub-messages. PiperOrigin-RevId: 529100966	2 years ago

Joshua Haberman	df93cf65a2	Hide upb_MiniTableField.submsg_index with new `UPB_PRIVATE()` macro The fields of upb_MiniTableField are intended to be internal-only, accessed only through public functions like `upb_MiniTable_GetSubMessageTable()`. But over time, clients have started accessing many of these fields directly. This is an easy mistake to make, as there is no clear signal that the fields should not be used in applications. This makes the implementation difficult to change without breaking users. The new `UPB_PRIVATE()` macro appends an unpredictable string to each private symbol. This makes it very difficult to accidentally use a private symbol, since users would need to write something like `field->submsg_index_dont_copy_me__upb_internal_use_only`. This is still possible to do, but it leaves a clear wart in the code showing that an an encapsulation break has occurred. The `UPB_PRIVATE()` macro itself is defined in `port/def.inc`, which users cannot include directly. Once we land this, more such CLs will follow for the other fields of `upb_MiniTable*`. We will add inline functions as needed to provide the semantic functionality needed by users. PiperOrigin-RevId: 523166901	2 years ago

Joshua Haberman	c642e43a5a	Allow fuse/fuse races, so that upb_Arena is fully thread-compatible. Previously upb_Arena was not thread-compatible when `upb_Arena_Fuse(a, b)` and `upb_Arena_Fuse(c, d)` executed in parallel if `b` and `c` were previously fused. This CL fixed that by allowing `upb_Arena_Fuse()` to run in parallel without limitations. Details on the design of the algorithm are captured in comments. The CL slightly improves the performance of `upb_Arena_Fuse()`. ``` name old cpu/op new cpu/op delta BM_ArenaOneAlloc 20.0ns ±19% 17.5ns ± 4% -12.30% (p=0.000 n=19+17) BM_ArenaInitialBlockOneAlloc

Joshua Haberman	73489a9339	Removed the cleanup list It no longer has any users. If we need it later, we can add it back. This saves one pointer of memory from `sizeof(upb_Arena)`. Also, we now allow fuses if if the block allocators differ. This is made possible by cl/520144430, but was not take advantage of in that CL. PiperOrigin-RevId: 520174588	2 years ago
Joshua Haberman	a73852630f	Changed Arena representation so that fusing links arenas together instead of blocks. Previously when fusing, we would concatenate all blocks into a single list that lived in the arena root. From then on, all arenas would add their blocks to this single unified list. After this CL, arenas keep their distinct list of blocks even after being fused. Instead of unifying the block list, fuse now puts the arenas themselves into a list, so all arenas in the fused group can be iterated over at any time. This design makes it easier to keep each individual arena thread-compatible, because fuse and free are now the only mutating operations that touch state that is shared with the entire group. Read-only operations like `SpaceAllocated()` also iterate the list of arenas, but in a read-only fashion. (Note: we need tests for SpaceAllocated(), both single-threaded for correctness and multi-threaded for resilience to crashes and data races). Performance of fuse regresses by 5-20%. This is somewhat expected as we are performing more atomic operations during a fuse. ``` name old cpu/op new cpu/op delta BM_ArenaOneAlloc 18.4ns ± 6% 18.7ns ± 4% +2.00% (p=0.016 n=18+18)
