perf: Parse HogQL with C++ for a huge speedup (#17659) * Add partial C++ parser of HogQL * Support all the rules and add proper error handling * Use `AlignAfterOpenBracket: BlockIndent` * Reuse all the parser tests for the C++ backend * Fix relationship between headers and implementations * Add more error handling and fix minor issues * Build both Python and C++ parsers in the package.json script * Update ARRAY JOIN error assertion * Improve timeit * Move the C extension to the top level * Refactor `vector_to_list_string` * Build the parser on Linux * Build wheels for the parser * Simplify Linux build and fix macOS * Fix Homebrew paths on x86 and don't fail fast in CI * Set MACOSX_DEPLOYMENT_TARGET for C++20 * Set up QEMU for Linux ARM builds * Publish the wheels on PyPI * Avoiding Linux ARM emulation in CI for now * Build sdist too * Revert Dockerfile changes * Fix PyPI publish * Add README and optimize sdist build * Use setup.py directly instead of build * Use PyPI hogql-parser instead of local * Also revert production-unit.Dockerfile * Fix sdist upload and add Linux ARM back * No Linux ARM build in the end * Fix artifact uploading * Do try building Linux ARM We need this for prod. * Use `npm` in `grammar:build` `pnpm` is not available in that job. * Fix formatting of hogql_parser * Build everything on macOS * Revert "Build everything on macOS" Not so fast actually. * Use hogql-parser=0.1.1 * Fix dylib in macOS wheel * Bump hogql-parser version * Fix missing module error * Delete timeit.py * Make error handling robust * Format the C++ * Use `hogql-parser==0.1.1` * Fix reserved keyword error assertions * Use HEAD hogql_paresr in CI * Fix `apt` usage * Add some sudo in CI * Ensure package will be releasable before build * Bump version to 0.1.3 * Cover C++ `unquote_string` with tests * Use BuildJet ARM runners for ARM builds * Add some instructions * Add HogQL version check to backend CI * Update requirements.txt * Use `setuptools` instead of the deprecated `distutils` * Fix working dir in backend CI * Align ANTLR versions * Add test for "mismatched input" This is thrown differently than other HogQLSyntaxExceptions in C++, so might help reveal what's going on with tests failing only on Linux CI and not macOS dev * Add types and bump version * Comment instead of failing version check * Automate hogql-release version bump * Fix checkout token * Don't build hogql-parser if there were no changes * Update query snapshots * Update query snapshots * Update query snapshots * Update query snapshots * Improve documentation * Use new hogql-parser version * Fix error start and end initialization * Note `antlr4-cpp-runtime` Co-authored-by: Marius Andra <marius.andra@gmail.com> * Also remove NUL chars in C++ * Check ANTLR4 runtime archive checksum for security * Note more decrefs to add * Add vector size checks * Use new hogql-parser version * Don't support the `start` arg in C++ `parse_expr` * Use new hogql-parser version --------- Co-authored-by: github-actions <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Marius Andra <marius.andra@gmail.com>
