- the inproc-acceptance leg excludes, by exact name, every integration-gpu entry whose own ENVIRONMENT sets MOBILEGL_TRANSPORT (inproc, spawn and monolith pins) and the fixtures only they require; their pin overrides the one variable the legs differ in, so the monolith-control leg's run is the same run
- transport_pinned.py selects them, proves the trimmed ctest selection lost exactly that set (or the leg runs everything, with a warning rather than an error), and proves in the monolith-control leg that every one of them ran; self-test in pipe-gates
- skip census: junit-integration-monolith-control-monolith/integration and integration-staged-copy get their own name lists; the inproc-acceptance lanes drop the pinned names (3628 -> 1450, 888 -> 336); arm-monolith and arm-inproc borrow from monolith-control
- a baseline row may carry "optional": "<reason>": the lane's absence is a note, and when it runs it is checked like any other lane
- write keeps an optional row (names resolved) when the run did not produce that lane, and keeps the reason on rows it rewrites
- self-test: an absent optional lane is green, a present one with a new skip is red, a plain lane stays required
- scripts/ci/configure_build.sh holds build-linux's (primary) and build-linux-split's (split) configure lines, flag for flag as before
- scripts/ci/build_fingerprint.py compares two configured trees (cache, compile commands, link statements, CTest files, toolchain) with the build path normalised and the benchmarks left out; its guard configures a probe through the script and never counts thin evidence as equal
- pipe-gates runs its self-test; no job uses the guard yet
- Strict split lane: drop the kMGPipeP5eRunAheadReady grep and its red-by-design pre-flip arm; the constant is true, so the arm never ran
- Dual-block census lane: drop the "green with rows outstanding" rule, inert while dualblock-expected-fatals.txt is empty; the empty-census rule and expect-fatal stay
- delete scripts/ci/tcp_log_forwarding_control.py, which nothing calls
- 'Split lanes' keeps its first ctest's exit code beside split-baseline.xml; the controls step tallies that JUnit (DirectGLES.Split. entries) with the same refusals instead of re-running 802 entries, on every branch
- the rerun stays as the fallback when the lane step never ran, the case where the baseline was the only run of those entries
- smoke cases: reuse, fallback, a red exit code under a green JUnit, and a JUnit with no DirectGLES.Split. entry
- skip census: retire lane junit-integration-split/isplit (nothing borrows it; split-baseline covers the names)
- retrace-split loses its two negative controls, which re-ran every leg (~68 runner-min per run), and its dependency on the monolith-control artifact; the in-test evidence check from the previous commit replaces them
- build-linux-monolith-control keeps its zero-MG_Remote proof and its upload; on the disaggregation branches the new retrace-shipped job replays OpenRA on both backends through that library (elsewhere the retrace job's library has that shape), so the shipped shape is still replayed on every branch
- delete retrace_transport_control.sh, retrace_drop_draw_control.sh, their smoke cases and stub modes, and the uncalled redcheck_control_smoke_test.sh
- control-runtime/build-push-control leaves the eleven metadata loops; remove-artifact-clutter waits for retrace-shipped
- run_trace_case.cmake writes output/split-evidence.txt only after its transport assertions pass
- MGTRACE_WIRE_EVIDENCE (a harness name) turns on the library's counters and requires DrawVbo records on the wire and draws on the server role
- retrace-split's OpenRA legs ask for wire evidence; every split leg, and every inproc retrace row, checks its evidence file with retrace_split_evidence.py
- test_run_trace_case.py runs the real script on canned logs: each assertion goes red on its bad log, and pipe-gates runs it
- the red controls ran spawn_lane_parity and junit_tally main() uncaptured, so every passing run showed their ::error:: line as a failure annotation on the pipe-gates job
- quiet_main captures a gate's output; each red control now also asserts the reason it printed
Breaks the one process = one server = one session = one context equation
that the whole stack's correctness used to rest on. Design and per-slice
shape: docs/Disaggregated/design/11-state-ownership.md.
S1 wire: bind_context ring record (opcode 84) announces the current
context at the make-current edge; CreateContext/DestroyContext join the
SurfaceOp control frames; control revision 5 -> 6; the server keeps a
per-session token table and refuses unknown tokens by name.
S2 server: SessionRuntime per session with thread-scoped resolution
(singletons become fallbacks), per-thread gPipeInputs, per-session latch
domains, per-thread segment resolvers; the in-process unix supervisor
serves up to MOBILEGL_IPC_INPROC_MAX_SESSIONS (16) concurrent sessions;
surface mode is declared per session and the display lease refuses a
second on-screen session by name.
S3 frontend: ShareGroupState owns the shared object stores and name
generators (buffer/texture/renderbuffer/sampler/program), GLContext keeps
per-context bindings/errors/container objects; pGLContext becomes
thread-local with a process default context preserving the single-context
world verbatim; eglCreateContext builds a real GLContext and joins the
sharing context's group.
S4 backend: native EGL tuples keyed by (session, context token);
InitDisplayAndContext's unconditional teardown is gone - creating a
second context or surface no longer destroys the first; eglCreateContext
sharing is wired to the native driver; bind_context is the native switch
point.
S5 applier: MGPipeApplierState splits into MGPipeObjectRecords (per
share group) and MGPipeWorkingState (per context), resolved through a
{session, token} registry with a thread-local cached fast path.
Tests: MultiSessionTest (incl. two sessions x two contexts interleaved
with real clear/readback witnesses), ApplierOwnershipTest (with a
null-resolver negative control), ContextStateOwnershipTest,
ServerLoopEglTest native-context liveness; 99/99 of the acceptance set
green on the host build.
Known debts (documented in the design doc): twin registries still keyed
by handle alone, no per-record ContextSlot, process-global backend
generations, MakeCurrent dedup per current binding.
