Known issues — current

Status as of v1.0.0-rc27 (2026-05-17). The historical M3-era compat-breaking CDX / NTX list that lived here is closed and now only survives in git log.

X# AXDBFCDX RDD — minor gaps

The full tests/smoke/xsharp/AdsSmoke.prg + AdsSmoke_remote.prg flow passes (rc19), but a handful of ADSRDD.prg entry points still resolve to AE_FUNCTION_NOT_AVAILABLE so the X# runtime falls back to its own client path. The X# RDD keeps working — but applications that explicitly depend on these calls will hit the not-available path.

  • AdsEval*Expr family — server-side expression evaluation helpers used by ADSRDD.prg’s server-side query path. The client-side fallback handles every common case.
  • A handful of AdsStmt* helpers used by the X# SQL surface.
  • The RI / unique / autoinc enforcement toggles are accept-and-ignore (the underlying enforcement still happens through AdsCreateIndex / DD).

See rddads / X# RDD compat for the full list of versioned overloads and what each one does.

Wire-protocol forward-only prefetch

M12.21 prefetch (forward-only row look-ahead on Skip(+N)) was disabled in M12.21b (rc9) after cursor-drift regressions on indexed scans. The wire still benefits from the row cache (M12.17), nav-ack trailer (M12.18), and record-count cache (M12.19), but speculative read-ahead is currently off.

Studio LocalServer auth

LocalServer mode (the Studio embedded in ace64.dll / ace32.dll) currently has no HTTP Basic auth. The default bind host is 127.0.0.1, so a desktop app does not silently expose its data dir to the LAN — but if you set OPENADS_STUDIO_HOST=0.0.0.0, put the console behind a reverse proxy that handles authentication. Remote Server mode (openads_serverd) supports --http-user user:password.

Studio HTTPS

The embedded HTTP console (cpp-httplib) only ships TLS via OpenSSL, which isn’t bundled in the daemon to keep the release binary lean. Terminate HTTPS in front with Caddy / nginx / stunnel / SSH tunnel — see TLS deployment for the recipes. A dedicated OPENADS_WITH_OPENSSL=ON CMake option is on the roadmap.

Closed in v1.0.0-rc1 .. rc27

See CHANGELOG.md for the full per-release breakdown. The big ones since the M3-era list:

  • M3 CDX / NTX compat-breaking issues — all closed by M3.6 .. M3.10 (bBits formula, compound structure-tag, branch descent endian / offset, multi-tag-per-file, multi- level NTX, descending / unique round-trip, deleted records excluded from AdsCreateIndex).
  • TLS — shipped in v0.4.0 (M12.12 / M12.13).
  • AOF / Rushmore — shipped in v1.0.0-rc12; AdsSetAOF no longer fails on non-optimisable expressions since rc21.
  • X# AXDBFCDX RDD compatibility — shipped in v1.0.0-rc19 (M12.22 / M12.23), full local + remote.
  • DBF header last-update date — shipped in rc21 (M12.24) and rc22 (M12.25 stamps on create).
  • Embedded Studio (LocalServer mode) — shipped in v1.0.0-rc9.
  • Wire perf (~30× xbrowse repaint) — shipped in rc18 via M12.17..M12.20.
  • Windows Service + systemd / launchd units — shipped in rc14.
  • AdsMg* server telemetry — shipped in v1.0.0-rc24; the ~17 management functions report real figures instead of zero-fill stubs.
  • Index correctness — shipped in v1.0.0-rc25: AdsCreateIndex61 decoded the wrong option bit (built every CDX / NTX tag descending), ALIAS->FIELD index keys were unparseable, and not-positioned reads returned generic 5000 instead of AE_NO_CURRENT_RECORD (5026).
  • PHP binding — shipped in v1.0.0-rc26; bindings/php (openads/openads-php) is a pure-PHP FFI package wrapping the ACE library, with a modern OOP API. The same release fixed the SQL parser’s missing '' string-escape handling. rc27 added Cursor::fetchAssoc/fetchNum and Table::seek.
  • AdsGetField CHARACTER padding — shipped in v1.0.0-rc27; CHAR fields were returned with trailing spaces stripped, so Harbour mini_xbrowse /ads auto-sized and truncated text columns. AdsGetField now pads CHAR values to the declared field width. The same release restored tools/harbour_patch/rddads-compat.patch (a dropped context line had broken git apply).

File issues at github.com/FiveTechSoft/OpenADS/issues. For X# RDD specifics, include the ADSRDD.prg entry point that returned AE_FUNCTION_NOT_AVAILABLE and the exact call site — that’s what drove the M12.22 / M12.23 batches.
