Adam Cozzette	501ececd39	Reorganize upb file structure This change moves almost everything in the `upb/` directory up one level, so that for example `upb/upb/generated_code_support.h` becomes just `upb/generated_code_support.h`. The only exceptions I made to this were that I left `upb/cmake` and `upb/BUILD` where they are, mostly because that avoids conflict with other files and the current locations seem reasonable for now. The `python/` directory is a little bit of a challenge because we had to merge the existing directory there with `upb/python/`. I made `upb/python/BUILD` into the BUILD file for the merged directory, and it effectively loads the contents of the other BUILD file via `python/build_targets.bzl`, but I plan to clean this up soon.

Adam Cozzette	7286ffceb2	Merge the protobuf and upb Bazel repos A couple weeks ago we moved upb into the protobuf Git repo, and this change continues the merger of the two repos by making them into a single Bazel repo. This was mostly a matter of deleting upb's WORKSPACE file and fixing up a bunch of references to reflect the new structure. Most of the changes are pretty mechanical, but one thing that needed more invasive changes was the Python script for generating CMakeLists.txt, make_cmakelists.py. The WORKSPACE file it relied on no longer exists with this change, so I updated it to hardcode the information it needed from that file. PiperOrigin-RevId: 564810016	1 year ago
Adam Cozzette	047df98dea	Move upb-x/ back to upb/ This is the second attempt to fix our Git history. This should allow "git blame" to work correctly in the upb/ directory even though our automation unexpectedly blew away that directory.	1 year ago

Joshua Haberman	7ebeb6006b	Fix the GitHub Actions for upb An earlier change inadvertently disabled several GitHub Actions due to a syntax error. This broke the CI for upb because several expected tests were never running. I was not able to get the Windows CI test fully working, so I disabled it for now.

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	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)

Joshua Haberman	d450990631	Allow for fuse/free races in `upb_Arena`. Implementation is by kfm@, I only added the portability code around it. `upb_Arena` was designed to be only thread-compatible. However, fusing of arenas muddies the waters somewhat, because two distinct `upb_Arena` objects will end up sharing state when fused. This causes a `upb_Arena_Free(a)` to interfere with `upb_Arena_Fuse(b, c)` if `a` and `b` were previously fused. It turns out that we can use atomics to fix this with about a 35% regression in fuse performance (see below). Arena create+free does not regress, thanks to special-case logic in Free(). `upb_Arena` is still a thread-compatible type, and it is still never safe to call `upb_Arena_xxx(a)` and `upb_Arena_yyy(a)` in parallel. However you can at least now call `upb_Arena_Free(a)` and `upb_Arena_Fuse(b, c)` in parallel, even if `a` and `b` were previously fused. Note that `upb_Arena_Fuse(a, b)` and `upb_Arena_Fuse(c, d)` is still not allowed if `b` and `c` were previously fused. In practice this means that fuses must still be single-threaded within a single fused group.
