777e35adae* feat(profiling): Tracy zones on p2p and memory-sync background paths Zone the memory-sync cycle (publish, sync, reconcile, apply, backfill, delete-outbox drain), the p2p reconnect cycle, accept loop, per-session worker and frame read, and the delta send/apply/bootstrap stages. Plot the retained session count and pending erase intents. No behavior change; the macros are no-ops without Tracy. Signed-off-by: trvon <me@trevon.dev> * test(infra): per-test-case CPU and peak RSS accounting for Catch2 binaries A Catch2 listener in the shared test main records getrusage (GetProcessTimes on Windows) CPU per case and prints the five heaviest cases plus the run's peak RSS to stderr at run end. YAMS_TEST_RUSAGE=1 adds one line per case. The measurement helpers are header-only and unit tested. Signed-off-by: trvon <me@trevon.dev> * fix(vector): make vector_database.cpp compile with Tracy enabled The Profiling lane did not build: eight YAMS_PLOT sites in vector_database.cpp used -> on a Result<T>, and two passed an int that is ambiguous between Tracy's PlotData overloads. Use .value() and int64_t casts. No behavior change outside TRACY_ENABLE builds. Signed-off-by: trvon <me@trevon.dev> * build: enable Tracy for every yams library in the Profiling lane Define yams_tracy_args/yams_tracy_deps once in the root meson.build (Tracy found, optional rocprofiler hooks, link check) and apply them to every library and executable under src/, replacing the per-library copies in search, topology, vector, daemon and tests/benchmarks. Empty when enable-profiling is off. Make YAMS_PLOT accept any numeric type and fix a Result deref in search_service so the newly instrumented TUs compile with Tracy.

# Tracy profiling
|
|
|
|
## Profiling lane
|
|
|
|
Build with Tracy in every yams library (`yams_tracy_args`/`yams_tracy_deps` in
|
|
the root `meson.build`; clients are built with `TRACY_ON_DEMAND`):
|
|
|
|
./setup.sh Profiling --with-tests # build/profiling
|
|
meson compile -C build/profiling -j12 catch2_memory_sync yams-daemon
|
|
|
|
Capture (client listens on 8086 by default; if taken it falls back to the next
|
|
free port, so find it with `ss -ltnp | grep <pid>`):
|
|
|
|
TRACY_NO_EXIT=1 build/profiling/tests/catch2_memory_sync &
|
|
tracy-capture -o run.tracy -a 127.0.0.1 -p <port> -f
|
|
tracy-csvexport -e run.tracy > zones.csv
|
|
|
|
Columns: `name,src_file,src_line,total_ns,total_perc,counts,mean_ns,min_ns,max_ns,std_ns`.
|
|
With `-e` (`--self`) the time columns hold self time instead of inclusive time;
|
|
export twice to get both.
|
|
|
|
Clients are `TRACY_ON_DEMAND`: zones fired before `tracy-capture` connects are
|
|
lost, so short tests need `TRACY_NO_EXIT=1` and a capture started while the
|
|
process is still alive, and the workload must run after the connect.
|
|
|
|
`tracy-capture` and `tracy-csvexport` must come from the same Tracy release as
|
|
the Conan client (`conan list "tracy/*"`); a mismatched protocol version is
|
|
rejected on connect. On grim they live in `/data/tracy-tools`, built with
|
|
`-DNO_FILESELECTOR=ON -DDOWNLOAD_CAPSTONE=OFF`.
|
|
|
|
With `enable-profiling=false` nothing changes: no args, no deps.
