From d7e58932e99b7db3552e81d32ee90cd8659ea1db Mon Sep 17 00:00:00 2001 From: Ken Johnson Date: Fri, 17 Apr 2026 14:32:38 -0700 Subject: [PATCH] Phase 4: kludge round-trip + cross-format capability tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds tests/test_roundtrip_attrs.pas covering: 1. Capabilities API smoke test — confirms SupportsAttribute('msgid') returns true on JAM/Squish/MSG/PKT, false on Hudson/GoldBase/ EzyCom/Wildcat/PCBoard. Confirms backend-private keys are gated correctly (Squish.SupportsAttribute('jam.msgidcrc') = false). 2. Per-format kludge round-trip across all 5 storage formats — builds a synthetic message with universal headers + FTSC kludges (msgid, replyid, pid, flags, multi-line seen-by + path), writes, reopens, reads back, asserts every key the backend's capability list advertises survives byte-for-byte. Backends that don't support a given key are silently skipped via SupportsAttribute gating so the test exercises each format's actual contract. 3. Cross-format JAM → Squish copy — seeds JAM with the kludge message, copies to a fresh Squish base via the unified API, reopens both, asserts: - intersection of capabilities lists is preserved verbatim (msgid, seen-by, path, etc. all survive JAM → Squish) - jam.* keys not in Squish's capability list are dropped (no silent corruption of Squish's data with foreign keys) Result: 7/7 new tests pass. Total suite now 31/31 across 8 programs. This is the regression suite that locks the Body+Attributes contract and proves the showstopper fix holds across every backend. Hooked into run_tests.sh so CI catches future drift. --- run_tests.sh | 2 + tests/test_roundtrip_attrs.pas | 355 +++++++++++++++++++++++++++++++++ 2 files changed, 357 insertions(+) create mode 100644 tests/test_roundtrip_attrs.pas diff --git a/run_tests.sh b/run_tests.sh index b2f7e08..eb6229f 100755 --- a/run_tests.sh +++ b/run_tests.sh @@ -39,6 +39,7 @@ run() { echo "Building tests..." compile tests/test_read.pas compile tests/test_roundtrip.pas +compile tests/test_roundtrip_attrs.pas compile tests/test_lock.pas compile tests/test_batch.pas compile tests/test_wildcat.pas @@ -49,6 +50,7 @@ echo echo "Running tests..." run test_read run test_roundtrip +run test_roundtrip_attrs run test_lock run test_batch run test_wildcat diff --git a/tests/test_roundtrip_attrs.pas b/tests/test_roundtrip_attrs.pas new file mode 100644 index 0000000..25b9334 --- /dev/null +++ b/tests/test_roundtrip_attrs.pas @@ -0,0 +1,355 @@ +{ + test_roundtrip_attrs.pas - verify the new Body+Attributes data + model preserves kludges (msgid, seen-by, path, etc.) across + Read/Write cycles, and that cross-format copies preserve every + attribute the destination's capabilities advertise. + + Catches the showstopper bug that prompted this design: previously + every adapter dropped MSGID/ReplyID/PID/Flags/SEEN-BY/PATH on the + way through TUniMessage.
