mongo-c-driver Validation Report

Generated 2026-08-24 — SecantusDB 0.6.0b15 vs mongo-c-driver 57dba9c (vendor/mongo-c-driver/).

Run uv run python -m invoke validate-c to refresh. The official MongoDB C driver (libmongoc) is the lowest-level official client — and (with the Go and PHP-extension gauges) one of the strictest wire-protocol checks.

How this is generated

invoke validate-c builds the vendored driver’s test-libmongoc binary once (CMake, ENABLE_TESTS=ON), spawns a SecantusDB daemon on a fresh ephemeral port, and runs the curated -l prefixes with MONGOC_TEST_URI pointed at the daemon, writing JSON results via -F. The list of in-scope test prefixes (and the skip-list of out-of-scope tests) lives in c_validation/include_paths.py.
