# testhost
|
||||
|
||||
A generic, headless command-line host for testing audio plugins. It loads a
|
||||
plugin out-of-process and drives it entirely offline — no audio device, no
|
||||
GUI event loop, no real-time pacing — so a test run is bounded by CPU speed
|
||||
rather than wall-clock playback time (60-1000x+ real-time observed on this
|
||||
machine, depending on the plugin).
|
||||
|
||||
**This tool is not JaySynth-specific.** It was built to test JaySynth, but it
|
||||
talks to plugins purely through JUCE's own `AudioPluginFormatManager` /
|
||||
`AudioPluginInstance` hosting API, and it never assumes a fixed channel
|
||||
layout — it always asks the loaded plugin how many input/output channels it
|
||||
actually has. That means it drives an instrument (0 inputs, MIDI-triggered,
|
||||
e.g. JaySynth) and an audio effect (real input required, e.g. a reverb,
|
||||
EQ, or compressor) through the exact same code path. See
|
||||
`/home/jens/.claude/plans/sharded-finding-tower.md` for the original design
|
||||
plan and rationale.
|
||||
|
||||
## Building
|
||||
|
||||
```sh
|
||||
MAKE_HOME=$(realpath ../../submodule/make) make -C tools/testhost
|
||||
```
|
||||
|
||||
This produces `tools/testhost/build/linux/release/testhost`. It has its own
|
||||
`JuceLibraryCode/` package (compiling only the module amalgams a host needs -
|
||||
not `juce_audio_plugin_client`, which is the plugin-*side* VST entry point
|
||||
and would collide with this executable's own `main()`), but reuses the
|
||||
already-vendored `sdk/juce/JUCE-3.1.1` rather than a second JUCE checkout.
|
||||
The host and any plugin it loads are decoupled at the VST2 ABI, not the JUCE
|
||||
source level, so this doesn't need to track JaySynth's own JUCE version.
|
||||
|
||||
`make CONFIG=debug -C tools/testhost` builds a debug variant the same way
|
||||
the main plugin build does.
|
||||
|
||||
## Quick start
|
||||
|
||||
```sh
|
||||
# Render 2s of a held note through JaySynth and record it:
|
||||
./build/linux/release/testhost \
|
||||
--plugin ../../build/linux/release/JaySynth.so \
|
||||
--note 60 100 --duration 2 --wav out.wav
|
||||
|
||||
# Feed pink noise through an audio effect (no MIDI needed):
|
||||
./build/linux/release/testhost \
|
||||
--plugin /usr/lib/vst/ZamDelay-vst.so \
|
||||
--input pink --duration 2 --wav out.wav
|
||||
```
|
||||
|
||||
Run `./build/linux/release/testhost --help` for the full flag reference
|
||||
(patch/bank load & save, parameters, sample rate/block size, performance CSV
|
||||
export, etc).
|
||||
|
||||
## JSON test scenarios
|
||||
|
||||
For anything beyond a one-off check, `--scenario file.json` drives a full
|
||||
timed sequence of actions instead of a handful of CLI flags - this is what
|
||||
makes tests repeatable and batchable (e.g. one file per regression case, run
|
||||
unattended in CI).
|
||||
|
||||
```json
|
||||
{
|
||||
"sampleRate": 44100,
|
||||
"blockSize": 512,
|
||||
"durationSeconds": 2.0,
|
||||
"input": { "type": "noise", "kind": "pink", "amplitude": 0.5 },
|
||||
"loadBank": "some_bank.fxb",
|
||||
"events": [
|
||||
{ "sample": 0, "type": "noteOn", "channel": 1, "note": 60, "velocity": 100 },
|
||||
{ "sample": 22050, "type": "param", "index": 5, "value": 0.75 },
|
||||
{ "sample": 44100, "type": "noteOff", "channel": 1, "note": 60 },
|
||||
{ "sample": 88199, "type": "savePatch", "file": "result_patch.bin" }
|
||||
],
|
||||
"recordWav": "out.wav"
|
||||
}
|
||||
```
|
||||
|
||||
Relative file paths inside the JSON (`loadBank`, `loadPatch`, `recordWav`,
|
||||
and any event's `file`) resolve against **the scenario file's own
|
||||
directory**, not the process's working directory, so a scenario file stays
|
||||
portable no matter where it's run from.
|
||||
|
||||
### Top-level fields
|
||||
|
||||
| Field | Type | Notes |
|
||||
|---|---|---|
|
||||
| `sampleRate` | number | default 44100 |
|
||||
| `blockSize` | number | default 512 |
|
||||
| `durationSamples` **or** `durationSeconds` | number | one of these is required |
|
||||
| `input` | object | `{"type": "silence"}` (default) / `"sine"` (+ `frequencyHz`) / `"noise"` (+ `kind`: `"white"`/`"pink"`) / `"impulse"`, all with optional `amplitude` (default 0.5) |
|
||||
| `loadPatch` / `loadBank` | string (file path) | loaded once, before rendering starts |
|
||||
| `recordWav` | string (file path) | omit to skip recording (e.g. pure performance runs) |
|
||||
| `events` | array | see below; need not be pre-sorted, `TestScenario` sorts by `sample` |
|
||||
|
||||
### Event types
|
||||
|
||||
All events have `sample` (absolute sample index) and `type`:
|
||||
|
||||
| `type` | Extra fields | Effect |
|
||||
|---|---|---|
|
||||
| `noteOn` | `channel`, `note`, `velocity` | `MidiMessage::noteOn`, timed to the exact sample within its block |
|
||||
| `noteOff` | `channel`, `note` | `MidiMessage::noteOff`, same timing precision |
|
||||
| `controller` | `channel`, `controllerNumber`, `controllerValue` | `MidiMessage::controllerEvent` |
|
||||
| `param` | `index`, `value` (0.0-1.0) | `AudioProcessor::setParameter`, applied at the start of the block containing `sample` (see caveat below) |
|
||||
| `loadPatch` / `loadBank` | `file` | reads the file's raw bytes and calls `setCurrentProgramStateInformation`/`setStateInformation` |
|
||||
| `savePatch` / `saveBank` | `file` | calls `getCurrentProgramStateInformation`/`getStateInformation` and writes the raw bytes out |
|
||||
|
||||
**Caveat:** MIDI events keep full per-sample timing (JUCE's `MidiBuffer`
|
||||
carries a sample offset natively). Non-MIDI events (`param`/`loadPatch`/
|
||||
`loadBank`/`savePatch`/`saveBank`) scheduled for a sample in the middle of a
|
||||
block are applied at the *start* of that block, not their exact offset -
|
||||
fine for test purposes, but not sample-accurate. Use a smaller `blockSize`
|
||||
if you need tighter timing on those.
|
||||
|
||||
### Patch/bank format note
|
||||
|
||||
`loadPatch`/`savePatch`/`loadBank`/`saveBank` read/write exactly the bytes
|
||||
that JUCE's host-side `AudioPluginInstance::get/setCurrentProgramState
|
||||
Information` and `get/setStateInformation` produce/consume for a hosted
|
||||
VST2 plugin - i.e. real `.fxp`/`.fxb` file bytes (JUCE's own VST2 host
|
||||
wrapper handles the fxb/fxp chunk header itself; this tool never parses
|
||||
that format directly). This is a different code path from JaySynth's own
|
||||
GUI-triggered "Load Patch from disk" button (`JaySynthAudioProcessor::
|
||||
loadPatchFromFile`/`patchImportXml` in `src/plug/PluginProcessor.cpp`) -
|
||||
both are legitimate ways to get a patch into the plugin, but they aren't
|
||||
the same call chain, so a fix to one doesn't automatically test the other.
|
||||
|
||||
## Architecture
|
||||
|
||||
- `PluginHost` — owns the `AudioPluginFormatManager`, loads/prepares/drives
|
||||
one plugin instance. The only class that talks to `AudioPluginInstance`
|
||||
directly; everything else in this tool is format-agnostic by construction.
|
||||
- `AudioInputSource` — fills the plugin's input channels each block
|
||||
(silence/sine/noise/impulse).
|
||||
- `WavRecorder` — thin wrapper over `WavAudioFormat`/`AudioFormatWriter`.
|
||||
- `TestScenario` — parses the JSON format above into a sorted event list
|
||||
plus render/I-O config.
|
||||
- `PerformanceStats` — per-block timing, summary + optional CSV.
|
||||
- `main.cpp` — CLI parsing, and a single render loop shared by both the
|
||||
ad-hoc-flags path and the `--scenario` path (ad-hoc flags are converted
|
||||
into an equivalent in-memory `TestScenario` before rendering starts, so
|
||||
there's only one loop to maintain).
|
||||
|
||||
## Regression suite
|
||||
|
||||
`tests/run_tests.sh` uses this tool to dynamically test the findings
|
||||
tracked in the repo-root `TODO.md` - see `tests/README.md` for what each
|
||||
test covers (and its limits). It's also how a real, previously-unknown VCF
|
||||
buffer-sizing bug got found and fixed (see that file and the repo-root
|
||||
`TODO.md`'s Critical section).

# testhost TODO
|
||||
|
||||
Tracks known gaps and future work for `tools/testhost/`, the generic headless
|
||||
plugin test host (see `README.md` for what it does and how to use it, and
|
||||
`/home/jens/.claude/plans/sharded-finding-tower.md` for the original design
|
||||
plan). Nothing here blocks current use — Phases 1-4 of the plan are done and
|
||||
verified (PR https://git.jayfield.org/jens/JaySynth/pulls/1).
|
||||
|
||||
## Deferred by design (Phase 5 of the plan)
|
||||
|
||||
- [ ] **LV2 plugin format support.** JUCE 3.1.1 (the version currently
|
||||
vendored at `sdk/juce/JUCE-3.1.1`) has no LV2 hosting backend. Once
|
||||
JaySynth's own JUCE dependency is upgraded (or a custom `AudioPluginFormat`
|
||||
subclass is written against the current version), register it in
|
||||
`PluginHost`'s constructor alongside `VSTPluginFormat` - no other host code
|
||||
should need to change, since everything downstream talks to the
|
||||
format-agnostic `AudioPluginInstance`/`AudioProcessor` API already.
|
||||
- [ ] **VST3/LADSPA format support.** JUCE already ships
|
||||
`VST3PluginFormat`/`LADSPAPluginFormat` in this same vendored version -
|
||||
registering them is a one-line addition to `PluginHost`'s constructor,
|
||||
just not done yet since nothing has needed it.
|
||||
- [ ] **Windows build (`Makefile.win`).** The plan calls for mirroring
|
||||
`src/plug`'s Linux/Windows Makefile pattern; only the Linux side has been
|
||||
built and tested so far.
|
||||
|
||||
## Test coverage gaps
|
||||
|
||||
- [ ] **Only mono (1 in/1 out) and asymmetric (2 in/1 out) effect channel
|
||||
configs have been smoke-tested** (`ZamDelay-vst.so`, `ZamComp-vst.so`,
|
||||
`ZamEQ2-vst.so`). A genuinely stereo-in/stereo-out effect hasn't been run
|
||||
through yet - worth doing before relying on this tool for a stereo effect
|
||||
plugin specifically.
|
||||
- [ ] **No automated regression baseline comparison.** The plan's stretch
|
||||
goal: batch-render every `.fxp`/`.xmp` under `extras/sounds/` through a
|
||||
fixed note pattern and diff against stored baseline WAVs/checksums, to
|
||||
catch DSP or save-load regressions automatically instead of via one-off
|
||||
manual runs. Not built.
|
||||
- [ ] **No CI wiring.** Nothing currently runs `testhost` automatically on
|
||||
push/PR; it's a manual, opt-in tool for now.
|
||||
- [ ] **No unit tests for `TestScenario`'s JSON parsing itself** (malformed
|
||||
JSON, missing required fields, wrong types, out-of-range values) - only
|
||||
exercised indirectly via a couple of hand-written scenario files during
|
||||
development. Edge-case handling (e.g. a negative `sample`, an unterminated
|
||||
`noteOn` with no matching `noteOff`) is untested.
|
||||
- [ ] **Polyphony/multiple simultaneous notes untested** - only ever a single
|
||||
held note in all smoke tests so far.
|
||||
|
||||
## Investigate
|
||||
|
||||
- [ ] **JaySynth's compiled VST2 wrapper never advertises chunk support to
|
||||
the host, so real `.fxp`/`.fxb` sample files silently have no effect when
|
||||
loaded generically.** Found while building `tests/run_tests.sh`: loading
|
||||
a bundled sample under `extras/sounds/` via `--patch` produces byte-
|
||||
identical output to not loading anything (confirmed by diffing
|
||||
`--printParams`). The files are legitimately in VST2's opaque-chunk
|
||||
("FPCh") format, but JUCE 3.1.1's plugin-side VST wrapper
|
||||
(`juce_VST_Wrapper.cpp`, compiled into `JaySynth.so`) never sets
|
||||
`effFlagsProgramChunks` on the `AEffect` struct, so JUCE's own host-side
|
||||
`VSTPluginInstance::usesChunks()` returns false and silently no-ops both
|
||||
load and save. Not one of the tracked `TODO.md` (repo root) findings, and
|
||||
not attempted here - fixing it means patching JUCE's own VST wrapper,
|
||||
a bigger and riskier change than this pass's scope. See
|
||||
`tests/README.md` for the full writeup; `tests/run_tests.sh`'s round-trip
|
||||
tests work around it by using `testhost`'s own save output as the
|
||||
fixture instead of an external sample file.
|
||||
- [ ] **DPF-based plugins print a non-fatal assertion on load.** All three
|
||||
Zam*-vst.so plugins tested (built with the DISTRHO Plugin Framework) print
|
||||
`assertion failure: "fIsActive" in .../DistrhoPluginInternal.hpp` during
|
||||
`PluginHost::load()`, despite JUCE's `VSTPluginInstance::prepareToPlay`
|
||||
already sending `effMainsChanged`/`effStartProcess`. Rendering still
|
||||
completes correctly (confirmed via WAV output), so this looks like a
|
||||
DPF/JUCE VST2 lifecycle-ordering quirk rather than a testhost bug, but it
|
||||
hasn't been root-caused - worth a closer look if it turns out to affect
|
||||
correctness (not just log noise) for some other plugin.
|
||||
- [ ] **`WavAudioFormat`'s base-class doc comment says channel count "must
|
||||
be either 1 or 2"** (`AudioFormat::createWriterFor`'s Doxygen comment).
|
||||
`WavRecorder` passes through whatever `PluginHost::getNumOutputChannels()`
|
||||
reports with no clamping, and this has worked fine for the 1- and 2-channel
|
||||
plugins tested so far - but a plugin with more than 2 output channels
|
||||
hasn't been tried, so it's unconfirmed whether JUCE's WAV writer actually
|
||||
enforces that limit or the doc comment is just generic/stale boilerplate
|
||||
shared across format subclasses.
|
||||
|
||||
## Nice-to-have (not planned, just noted)
|
||||
|
||||
- [x] A `--list-params` or similar introspection mode (print every
|
||||
parameter's index/name/current value) would help writing new scenario
|
||||
JSON files without cross-referencing the plugin's own GUI or source.
|
||||
Done: `--printParams` (prints `PARAM <index> <value>` for every
|
||||
parameter, after any initial `--patch`/`--bank` load) - added to make
|
||||
the patch/bank round-trip regression tests in `tests/` possible; only
|
||||
prints values, not names, so cross-referencing the plugin's own
|
||||
parameter-name list is still occasionally needed.

# Regression suite for JaySynth's hardening findings
|
||||
|
||||
`run_tests.sh` uses `testhost` itself to dynamically exercise the findings
|
||||
tracked in the repo-root `TODO.md` (the "hardening" review) — no GUI, no
|
||||
manual clicking, runs in well under a second of wall-clock time.
|
||||
|
||||
## Running
|
||||
|
||||
```sh
|
||||
MAKE_HOME=/path/to/submodule/make ./run_tests.sh [path/to/JaySynth.so]
|
||||
```
|
||||
|
||||
Builds `testhost` first if it isn't already built. Defaults to
|
||||
`build/linux/release/JaySynth.so` if no path is given. Exit code is 0 if
|
||||
everything passed, 1 otherwise (CI-friendly). On failure, per-test logs and
|
||||
WAVs are kept in a `mktemp -d` workdir printed at the end; on success
|
||||
that workdir is deleted.
|
||||
|
||||
## What each test actually covers
|
||||
|
||||
**`oversized_blocksize`** (Critical #5) — renders through `--blockSize
|
||||
16384` (double `SYNTH_MAX_BUFSIZE`). Before the fix this either overflowed
|
||||
`processBlock`'s fixed 8192-sample stack buffer or deadlocked the render
|
||||
worker threads; `timeout` is what actually catches the deadlock case, since
|
||||
a hung process would otherwise just sit here forever. **This test is also
|
||||
what caught a second, previously-unknown bug**: `VCF_CalcCoeff_LPF/_HPF/_BPF`
|
||||
advance their coefficient-buffer pointer once per *(sample, filter-section)*
|
||||
pair, but the buffer was only ever allocated for `bufsize` samples, not
|
||||
`bufsize × sections` — a 4th-order filter (2 sections) overflowed it for
|
||||
any block between 4097 and 8192 samples, a range this fix's own "chunk to
|
||||
≤8192" logic doesn't protect against on its own. Found via AddressSanitizer
|
||||
after this test kept crashing at blockSize values *below* 8192; fixed in
|
||||
`src/synth/vcf.c` (see TODO.md's Critical section). If this test ever
|
||||
regresses again, don't assume it's the same bug — bisect the block size
|
||||
first (see the debugging notes at the bottom of this file for how that
|
||||
investigation went).
|
||||
|
||||
**`nrpn_out_of_range`/`nrpn_in_range`** (Critical #1) — sends the standard
|
||||
5-message MIDI NRPN CC sequence (99/98/6/38/98) via a JSON scenario, once
|
||||
targeting the maximum possible 14-bit NRPN ID (16383) and once a legitimate
|
||||
in-range ID (500). Both must complete cleanly; the in-range case exists so
|
||||
a regression that made the bounds check *too* aggressive (rejecting valid
|
||||
IDs) would also be visible as a behavioural difference. **Caveat:** "doesn't
|
||||
crash" is a necessary but not fully sufficient check here. The original bug
|
||||
was an out-of-bounds *write* into `last_midiCC_info[]`, a plain array
|
||||
embedded inside the larger heap-allocated `JaySynth` object — not a
|
||||
separate heap allocation — so an overflow of a few hundred entries lands in
|
||||
*other member fields of the same object* rather than past its heap
|
||||
allocation. That means it can silently corrupt adjacent state without
|
||||
necessarily crashing in a short test run, and it's why the ID is pushed to
|
||||
the actual maximum (16383) rather than something more modest: to maximize
|
||||
the chance that, absent the fix, the write would land far enough away to
|
||||
hit unrelated memory and actually crash. The real guarantee is the
|
||||
bounds-check line itself (`src/plug/JaySynth.cpp`, `handleController`), not
|
||||
this test's silence.
|
||||
|
||||
**`patch_save_load_roundtrip`** / **`bank_save_load_roundtrip`** — covers
|
||||
two related fixes: (a) `setCurrentProgramStateInformation` used to pass
|
||||
`patchImportXml` an XML node one level too deep, making the VST2 "copy
|
||||
plugin state" path a complete no-op; (b) the `patchDecodeXml`/
|
||||
`patchDecodeXml_legacy` deduplication and `patchImportXml`'s legacy-branch
|
||||
restructuring. Sets a continuous parameter (index 0 = `SYNTH_PARAM_VOLUME`)
|
||||
to a distinctive value, saves, reloads in a fresh process, and checks the
|
||||
value reads back within a small tolerance (not exact equality — the
|
||||
slider/internal-value scaling curve, `toParam`/`toSlider`, isn't bit-exact
|
||||
across a round trip). Uses `testhost`'s own save→load cycle as the fixture,
|
||||
not an externally-provided `.fxp`/`.fxb` — see the chunk-format note below
|
||||
for why.
|
||||
|
||||
**`stability_sweep`** — loads every bundled `.fxp` under `extras/sounds/`
|
||||
and renders a held note through each, checking for crashes/hangs/NaN. A
|
||||
broad regression net, not a targeted test for any one finding.
|
||||
|
||||
## Two things discovered while building this suite that are worth knowing
|
||||
|
||||
**The VCF coefficient-buffer bug above** (already fixed, see TODO.md).
|
||||
|
||||
**JaySynth's compiled VST2 wrapper never advertises chunk support to the
|
||||
host**, so loading the bundled sample `.fxp` files through `testhost`'s
|
||||
generic `--patch` (i.e. through `AudioProcessor::setCurrentProgramState-
|
||||
Information`, exactly what any real VST2 host uses) has **zero effect** —
|
||||
confirmed by diffing `--printParams` output with and without `--patch`.
|
||||
Those sample files are legitimately in VST2's opaque-chunk ("FPCh") format
|
||||
(verified via hex dump: correct `CcnK`/`FPCh`/`Jsy1` header), but JUCE
|
||||
3.1.1's plugin-side VST wrapper (`sdk/juce/JUCE-3.1.1/modules/
|
||||
juce_audio_plugin_client/VST/juce_VST_Wrapper.cpp`, compiled into
|
||||
`JaySynth.so`) never sets the VST2 `effFlagsProgramChunks` flag on the
|
||||
`AEffect` struct, so JUCE's own host-side `VSTPluginInstance::usesChunks()`
|
||||
sees false and `setChunkData()` silently no-ops — for both loading *and*
|
||||
saving. This is **not** one of the tracked `TODO.md` findings and this
|
||||
suite doesn't attempt to fix it (it would mean patching JUCE's own VST
|
||||
wrapper, a materially bigger and riskier change). It's why
|
||||
`stability_sweep` only checks "doesn't crash," not "changes the patch," and
|
||||
why the round-trip tests use `testhost`'s own save output as the fixture
|
||||
rather than a real sample file — `testhost`'s save path has the same
|
||||
`usesChunks()`-is-false behaviour, so save and load are at least
|
||||
consistent with *each other*, even though neither talks to the external
|
||||
`.fxp` files' actual chunk data. Tracked as a discovered issue in
|
||||
`tools/testhost/TODO.md`'s "Investigate" section.
|
||||
|
||||
## Debugging notes: how the VCF bug was actually found
|
||||
|
||||
`oversized_blocksize` initially failed with `free(): invalid next size
|
||||
(normal)` - glibc's heap-corruption detector, tripped during process
|
||||
teardown, not at the point of the actual overflow. Bisecting `--blockSize`
|
||||
found the real threshold was 4096/4097, not 8192 as expected. Rather than
|
||||
guess further, an ASan build of just `src/synth` + `src/plug` (env-var
|
||||
override: `CFLAGS/CXXFLAGS="-fsanitize=address -fno-omit-frame-pointer -g
|
||||
-O1" LDFLAGS="-fsanitize=address"`, `CONFIG=asan` to keep it in its own
|
||||
build directory) run via `LD_PRELOAD=$(clang -print-file-name=libclang_rt.
|
||||
asan-x86_64.so)` pinpointed it exactly. Two gotchas worth remembering if
|
||||
this needs doing again: (1) `ASAN_OPTIONS=symbolize=0` is necessary in this
|
||||
environment — the default external `llvm-symbolizer` fork hangs
|
||||
indefinitely rather than resolving addresses, so use `symbolize=0` and
|
||||
resolve the reported `JaySynth.so+0x...` offsets with `addr2line -e
|
||||
JaySynth.so <offset>` (or just `nm`/`objdump` if `addr2line` needs exact
|
||||
offsets adjusted for the binary's load bias) instead of trusting ASan's own
|
||||
backtrace; (2) rebuilding the ASan variant needs a real `git worktree`
|
||||
avoided here — `sdk/juce/JUCE-3.1.1` is vendored as a zip+patch pair
|
||||
extracted on demand, not a plain tracked directory, so a fresh worktree
|
||||
doesn't have it. Simpler to `git stash` uncommitted work and build the
|
||||
ASan variant directly on the branch with the fix under investigation.
