Summary: This continues and finishes **https://github.com/facebook/rocksdb/issues/14572** ("Add semi-automated code generation for RocksDB C API bindings") by xingbowang. The original author is unavailable to finish it, so I've taken it over. **All 13 of the original commits are preserved** (this branch was created from the PR head and builds on top of it — `git log` shows the original `Xingbo Wang` authorship intact); my follow-up work is in the commits prefixed `C API codegen:`. The underlying design is unchanged and is the original author's: hand-written source templates (`tools/c_api_gen/c_base.h` / `c_base.cc`) plus two generators (auto-discovery from the C++ headers + a spec-driven generator) are inlined into a single, self-contained, `generated` `include/rocksdb/c.h` and `db/c.cc`. This grows the public C API by **668 functions** while keeping `c.h` a single includable header with no `-I` requirement (so `bindgen` and other FFI tools keep working unchanged). This branch reconciles the PR with ~4 months of `main` and addresses the outstanding review feedback (clang-tidy bot, the automated code review, the `c.h` self-containedness discussion, and pdillinger's points about `include/rocksdb` hygiene and `generated` marking). ## What changed on top of the original PR ### Reconciled with current `main` - Merged current `main` (conflicts were confined to the generated/test files) and regenerated. Reconciled the 14 C API functions `main` added since the merge-base (e.g. `rocksdb_set_db_options`, the backup-engine rate limiters, `memtable_batch_lookup_optimization`, `optimize_multiget_for_io`, …) and restored 5 enum constants that upstream had added by hand (`rocksdb_txndb_write_policy_*`, `..._index_block_search_type_auto`, `rocksdb_blob_cache_read_byte`). ### Maintainer feedback (pdillinger) - **No non-user-includable files in `include/rocksdb`.** Moved the hand-written templates out of `include/rocksdb/` and `db/` to `tools/c_api_gen/c_base.{h,cc}`. They were `#include`-ing generated fragments, which broke `make check-headers` and was shipped by `make install`. `include/rocksdb/` now contains only the user-facing, self-contained, `generated` `c.h`. - `c.h` / `c.cc` carry the `// generated` marker. ### Backward compatibility (zero ABI break) - The generator derived each wrapper's C type purely from the C++ field, which had silently changed **5 already-shipped signatures** (e.g. `rocksdb_writeoptions_disable_WAL` `int` → `unsigned char`). Added an ABI type-pinning layer (`tools/c_api_gen/abi_type_overrides.json`) so already-shipped functions keep their historical C signature (the body still casts to the real field type). A repo-wide diff against the merge-base now reports **0 ABI drift**. - New `check_api_compatibility.py` gate (wired into CI + `make`) fails on any removed/changed public function **or** removed enum/typedef symbol, vs a reference revision. Intentional changes go in an allowlist with a reason. ### Correctness (from the automated review) - Restored 5 option setters that were declared in `c.h` but **defined nowhere** (link failure for downstream bindings such as `rust-rocksdb`). Added `check_api_completeness.py` (dependency-free; runs in CI + `make`) asserting every declared function has exactly one definition — this is the gate that would have caught it. - `CopyStringVector` now null-checks `malloc`; the WAL filter `std::move`s the `WriteBatch`; the backup exclude-files callback captures by value instead of the wrapper pointer. ### Build / CI robustness - Removed the dead `C_API_CODEGEN_STAMP` Makefile prerequisite (it was a silent no-op). - The `make check` staleness check is now opt-out-able (behind `SKIP_FORMAT_BUCK_CHECKS`) and skips gracefully when `clang++` is unavailable, so `make check` works without the codegen toolchain. CI remains the authoritative gate. - Pinned `clang-format` consistently through `regen_all.py` / `verify_generated_up_to_date.py` (CI uses clang-format-21) so regeneration is byte-reproducible across environments. - Cleared all 20 `clang-tidy` warnings the bot reported on `db/c.cc` changed lines (fixed in the `c_base.cc` template, not the generated output). - Updated the internal Buck `c_test_bin` wrapper to expose generated `c_api_gen/*.inc` fragments as headers, so sandboxed Buck builds can compile `db/c_test.c` after the generated round-trip tests are included. ### Test coverage - Added `gen_roundtrip_tests.py`, which derives **462 set→get→assert round-trip checks across 25 option objects** from the same generated fragments and wires them into `db/c_test.c`. Coverage now tracks the generated surface automatically. ### Docs - Added the `unreleased_history/public_api_changes` note and fixed `claude_md/add_public_api.md`, which still told contributors to hand-edit the now-`generated` `c.h`/`c.cc`. Pull Request resolved: https://github.com/facebook/rocksdb/pull/14868 Test Plan: - `make c_test && ./c_test` — **passes**, including the 462 generated round-trip assertions (a successful link also confirms the API is complete). - `python3 tools/c_api_gen/check_api_completeness.py` — all 1737 declared functions defined exactly once. - `python3 tools/c_api_gen/check_api_compatibility.py --ref <release>` — 1070 reference functions + 229 enum/typedef symbols preserved, 0 removed/changed. - `python3 tools/c_api_gen/verify_generated_up_to_date.py` — generated output is stable. - `include/rocksdb/c.h` confirmed self-contained (only `<stdbool.h>`, `<stddef.h>`, `<stdint.h>`). cc xingbowang - `buck2 build --flagfile fbcode//mode/dev fbcode//internal_repo_rocksdb/repo:c_test_bin` — passes. - `buck2 build --flagfile fbcode//mode/dev --config fbcode.arch=aarch64 fbcode//internal_repo_rocksdb/repo:c_test_bin` — passes.

Does not support:
|
|
. getters for the option types
|
|
. custom comparators that implement key shortening
|
|
. capturing post-write-snapshot
|
|
. custom iter, db, env, cache implementations using just the C bindings
|
|
|
|
Some conventions:
|
|
|
|
(1) We expose just opaque struct pointers and functions to clients.
|
|
This allows us to change internal representations without having to
|
|
recompile clients.
|
|
|
|
(2) For simplicity, there is no equivalent to the Slice type. Instead,
|
|
the caller has to pass the pointer and length as separate
|
|
arguments.
|
|
|
|
(3) Errors are represented by a null-terminated c string. NULL
|
|
means no error. All operations that can raise an error are passed
|
|
a "char** errptr" as the last argument. One of the following must
|
|
be true on entry:
|
|
*errptr == NULL
|
|
*errptr points to a malloc()ed null-terminated error message
|
|
On success, a leveldb routine leaves *errptr unchanged.
|
|
On failure, leveldb frees the old value of *errptr and
|
|
set *errptr to a malloc()ed error message.
|
|
|
|
(4) Bools have the type unsigned char (0 == false; rest == true)
|
|
|
|
(5) All of the pointer arguments must be non-NULL.
