Mike Kruskal	543fbcdbd9	Breaking change: Remove deprecated std::string error collector overrides PiperOrigin-RevId: 590740727	12 months ago
Eric Salo	a303ccbe05	upb: use upb_alloc functions internally instead of stdlib malloc/free PiperOrigin-RevId: 589864832	12 months ago
Protobuf Team Bot	fa15c2160e	Fix upb's json decoder ignoring trailing characters after a successfully parsed object. This is a breaking change since the JSON parser will now correctly reject certain bad inputs that it previously silently accepted (for example: json="{}x" was accepted). PiperOrigin-RevId: 580493003	1 year ago
Joshua Haberman	cf3a6f5868	Enabled editions support for upb generated code. This required enabling the feature in the code generator and fixing a few edge cases around label and type. Also added tests to verify the special cases, and to verify that required fields work as expected. PiperOrigin-RevId: 580263087	1 year ago
Joshua Haberman	c69dd68fb1	Implement feature inheritance and legacy editions for upb. This switches upb to using legacy editions for all proto2/proto3 logic. This does not yet enable code generation for editions protos (ie. we do not yet turn on `FEATURE_SUPPORTS_EDITIONS`), but with feature inheritance in place, this will be a much smaller follow-on change. There is a ~10% increase in allocations, but only a ~1% increase in peak memory. There are some <5% increases in instructions and cycles, but apparently no increase in time: ``` name old cpu/op new cpu/op delta BM_ArenaOneAlloc 17.8ns ±11% 16.9ns ±17% ~ (p=0.310 n=5+5)

Eric Salo	07fba1da07	upb: merge ":collections" into ":message" PiperOrigin-RevId: 569594353	1 year ago
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.

Joshua Haberman	79af13abde	Use filegroup() internally instead of pkg_files() pkg_files() has some odd quirks, like breaking if a filename exists in multiple directories. filegroup() does everything we need, without these quirks. PiperOrigin-RevId: 547523447	1 year ago

Protobuf Team Bot	b32938176d	Delay defining Group constructor until after UnknownField is a complete type. C++20 requires that types used in std::vector are complete. Group's constructor definition requires that UnknownFields' destructor be available, which means UnknownField must be complete. PiperOrigin-RevId: 527341365	2 years ago
Joshua Haberman	b81ae408b0	Fixed the upb.lexan build: - Fixed a couple of broken tests that were probably invoking UB. - Excluded python/... and js/..., as these do not work with Windows. PiperOrigin-RevId: 525228589	2 years ago

Joshua Haberman	2d40e1e2ee	Removed some special escapes from def_to_proto.c, to match C++ protos. This was not a bug -- the previous behavior was correct. However this change brings our implementation-specific details in line with C++. PiperOrigin-RevId: 511273853	2 years ago

Joshua Haberman	1b50271ca2	Fixed a bug in the matcher that caused false positives. Previously we were calling the static method `Equals()` which did not take into effect the custom comparator or string for reporting errors. PiperOrigin-RevId: 507344425	2 years ago
Joshua Haberman	6e1cbdfe09	Added fuzzer for descriptor parsing/serialization, and fixed several bugs. The initial motivation for this change was to fix a bug found by fuzzing. The old fuzz test (built on `cc_fuzz_target()`) detected an infinite loop if a bytes field default has an unterminated `\x` escape. To fix this bug while expanding fuzz coverage, I created a fuzz test that verifies that we can do a lossless round trip from descriptor -> DefPool -> descriptor. We use C++ as the source of truth for whether a descriptor is valid or not, and what the canonical serialization back to protobuf form should be. I wrote the new fuzz test using go/FuzzTest, which makes it easier and more readable to use an arbitrary `FileDescriptorSet` as input, while adding test cases for regressions. The fuzz test highlighted a handful of errors that I subsequently fixed and added regression tests for: 1. The aforementioned unterminated `\x` bug. 2. We were not propagating the `edition` field. 3. We were missing the CheckIdent() check in a few places. 4. We were rejecting files with empty name, whereas C++ allows this. 5. There were a few bugs with escaping string defaults. Since FuzzTest is Clang-only, I split the `FUZZ_TEST()` invocation from the regression tests, since the latter are portable and should be run on all platforms. Only `FUZZ_TEST()` itself is in a google3/Clang-only file. PiperOrigin-RevId: 506997362	2 years ago

According to https://en.cppreference.com/w/c/program/setjmp automatic variables modified in a function calling setjmp can have indeterminate values.

Joshua Haberman	75488a0742	Created a new upb_WireReader interface for parsing wire data directly. The overall motivation for this interface is to consolidate many places in upb that are parsing wire format data directly. This interface is not yet complete, but this is a good start. We have enough to port the wire format parsing in accessors.c to this interface. We can follow up by porting more places that do wire format parsing. PiperOrigin-RevId: 498109788	2 years ago
