With this growth comes a problem: **how do we allow the community to contribute plugins without requiring a full PlotJuggler recompilation for each update?** + +The answer is the **PlotJuggler Marketplace**, an extension distribution system inspired by the VSCode model. The core idea is simple: a user opens the marketplace inside PlotJuggler, searches for "ROS 2", clicks "Install", and within seconds has the plugin running. No compilation, no dependency management, no worrying about Qt versions. + +To achieve this, the system relies on a completely **serverless architecture**: no backend to maintain, no infrastructure costs. Everything lives on GitHub — a JSON file with the plugin catalog and binaries distributed as GitHub Releases. Plugin developers use a GitHub template that automates everything: they push a tag and the CI compiles for Linux, Windows and macOS, packages the binaries, and updates the catalog automatically. + +The most interesting technical challenge is **ABI compatibility**. Historically, PlotJuggler plugins depended on Qt, which meant that a plugin compiled with Qt 5.15 wouldn't work with PlotJuggler compiled with Qt 6.2. The adopted solution is radical: **plugins no longer depend on Qt at all**. They define their UI through .ui files (pure XML) and use an abstract SDK for logic. PlotJuggler renders the UI and routes events. This eliminates the compatibility problem at its root. + +Development will begin with a standalone prototype to validate the concept, with subsequent native integration into PlotJuggler 4. + +--- + +## Table of Contents + +1.

System Architecture + +### 3.1 Overview + +One of the first decisions was to avoid the complexity of maintaining a backend server. The key question was: *do we really need a server to distribute 30-50 plugins?* The answer is no. + +GitHub provides everything we need for free: + +- **Registry:** A simple JSON file in a repository. PlotJuggler downloads it via `raw.githubusercontent.com`, caches it locally, and that's it. +- **Artifacts:** Binaries are distributed as GitHub Releases. They're static URLs, with global CDN, no practical download limits. +- **Updates:** When a developer publishes a new version, their CI generates an automatic Pull Request to the registry repository. The schema is validated, URLs are verified, and it gets merged. + +This architecture has an additional advantage: **any company can have their own private registry** simply by pointing PlotJuggler to another repository. No lock-in. + +### 3.2 Component Diagram + +![System Architecture](diagrams/architecture.png) + +### 3.3 Design Principles + +The design is guided by several principles that emerged from previous experiences with plugin systems: + +| Principle | Why it matters | +| ---------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| **Serverless** | Zero infrastructure costs, zero server maintenance. GitHub does the heavy lifting. | +| **CI-first** | Developers shouldn't have to configure anything beyond using the template. Push a tag = automatic release. | +| **Cross-platform** | PlotJuggler runs on Linux, Windows, and macOS. Plugins must work on all three platforms without developers needing all three machines. | +| **Static linking** | A plugin is a single .so/.dll file that works without installing anything else. This drastically simplifies installation and avoids dependency conflicts. | +| **Zero Qt in plugins** | This is perhaps the most important principle. If plugins depend on Qt, any Qt version change breaks all plugins. By removing Qt from plugins, the problem disappears. | +| **Dogfooding** | Official plugins (ROS 2, MCAP, etc.) use exactly the same process as external contributors. This ensures the process works and is well documented. | + +--- + +## 4. Design Decisions + +### 4.1 PlotJuggler Integration + +Two approaches were considered: create an external plugin management tool (like `pip` or `npm`) or integrate it directly into PlotJuggler. The decision was clear: **native integration**. + +The reasoning is that the typical PlotJuggler user doesn't want to leave the application to install plugins. They want to open a window inside PlotJuggler, search for what they need, install it, and keep working. It's the VSCode experience, not managing packages from a terminal. + +That said, development will begin with a **standalone prototype**. This allows rapid iteration without touching PlotJuggler's code, and validates that the concept works before committing to the architecture. Once validated, it will integrate as native functionality in PlotJuggler 4. + +### 4.2 Plugin Template as Product + +A key insight is that **the barrier to creating plugins is too high**. Configuring CMake, Conan, cross-platform CI... that's days of work before writing a single line of plugin code. + +The solution is a **GitHub Template** that developers use as a starting point. They click "Use this template", clone the repo, and have: + +- Preconfigured CI that compiles for Linux, Windows, and macOS +- Working Conan build system +- Project structure with examples +- Release workflow: creating a `v1.0.0` tag automatically triggers compilation, packaging, and publishing + +The goal is that a developer with C++ experience can have their first plugin published in the marketplace **in a day**, not a week. + +### 4.3 Build System: Conan, Pixi, and the Future + +The C++ ecosystem has multiple dependency managers, and PlotJuggler has used several over time: + +| Tool | Status | Context | +| ---------- | ----------------- | ---------------------------------------------------------------------------------------------------------- | +| **CMake** | Stable | It's the de facto standard.

Compatibility and ABI + +### 10.1 The Compatibility Problem + +Binary compatibility (ABI) is probably the biggest technical headache in any C++ plugin system. The typical scenario is: + +1. User installs plugin compiled with Qt 5.15.2 +2. User updates PlotJuggler to a version compiled with Qt 6.2 +3. Plugin crashes because Qt's internal structures have changed + +This problem has plagued PlotJuggler for years. Users report that "the ROS plugin stopped working after updating", and the only solution was to recompile the plugin. + +### 10.2 The Solution: Zero Qt in Plugins + +The adopted solution is radical but effective: **plugins no longer use Qt directly**. + +Instead of plugins creating Qt widgets, they do two things: + +1. **Define their UI in a .ui file:** It's pure XML, Qt Creator format. No compiled Qt code. +2. **Use an abstract SDK:** To read widget values, respond to events, etc. + +When PlotJuggler loads the plugin: + +1. It reads the .ui file and creates the corresponding widgets (using its version of Qt) +2. It connects those widget events to the plugin via the SDK +3. The plugin never touches Qt directly + +This means a plugin compiled today will continue to work when PlotJuggler migrates to Qt 7, or Qt 8, or whatever comes next. The contract is the SDK, not Qt. + +### 10.3 Compatibility Policy + +The commitment to plugin developers: + +- Each plugin declares `min_plotjuggler_version` in its manifest +- If the SDK changes incompatibly, PlotJuggler provides an internal adapter +- **Existing plugins are never broken by PlotJuggler updates** +- Stability target: Qt LTS 6.8 (support until 2028) + +--- + +## 11. Windows Management + +### 11.1 The Windows Problem + +Windows has an annoying quirk for plugin systems: **it doesn't allow modifying files that are in use**. If PlotJuggler has `ros2_streaming.dll` loaded, you can't delete it or overwrite it. + +On Linux and macOS this isn't a problem — you can delete a file that's memory-mapped, and the process keeps using the old version until it closes. But Windows locks the file completely. + +This means that on Windows, **you can't update a plugin while PlotJuggler is running**. + +### 11.2 Solution: Staging + +The solution is a staging system similar to what Windows installers use: + +![Windows Staging](diagrams/windows-staging.png) + +The flow is: + +1. User clicks "Update" +2. New version downloads to a temporary folder (`.pending/`) +3. Message shown: "Update will be applied when PlotJuggler restarts" +4. When PlotJuggler starts: + - Detects pending updates + - Backs up current version to `.backup/` + - Moves new version from `.pending/` to `extensions/` + - Loads the plugin +5. If plugin fails to load, automatically restores from backup + +### 11.3 Directory Structure + +``` +~/.plotjuggler/ +├── extensions/ ← Active plugins +│ ├── ros2-streaming/ +│ └── csv-loader/ +├── .pending/ ← Staging (Windows) +├── .backup/ ← Backups for rollback +│ ├── ros2-streaming-1.2.2/ +│ └── csv-loader-0.9.0/ +└── installed.json ← Local state +``` + +--- + +## 12.

This commit adds platform-aware staging logic: - Fresh install: installs directly (no DLL loaded yet) - Update: stages to .pending/ directory, applies on next startup - Uninstall: if directory removal fails, schedules deletion for next startup - Startup: applyPendingInstalls() and applyPendingUninstalls() process deferred work The ExtensionManager now exposes: - doInstall() private method for unified install logic with staging flag - installPendingRestart and uninstallPendingRestart signals for UI feedback - applyPendingUninstalls() for deferred directory cleanup Also adds constructor overload accepting an ExtensionManager* for test injection. Contents: - extension_manager.hpp: declare doInstall(), add pending restart signals - ExtensionManager.cpp: implement staging logic and pending uninstall scheduling - marketplace_window.cpp: add ExtensionManager* constructor, connect pending restart signals - extension_manager_test.cpp: add staging and pending uninstall tests - main_window.cpp: call applyPendingInstalls() and applyPendingUninstalls() at startup commit 1bd2e0b3bef7990ccc61e1c0df927857f5cac665 Merge: 497c4d5 aaebb7b Author: Pablo Iñigo Blasco Date: Tue Mar 31 10:12:41 2026 +0000 Merge branch 'fix/extension-manager-call-initcomponents-parametrized-ctor' into 'internal_main' fix(extension_manager): call initComponents() from parametrized constructor See merge request client-projets/p.2026-plotjuggler/plotjuggler_core!87 commit aaebb7b8f271bf700fea3d81168aaf3056ed5351 Author: Vlozano Date: Tue Mar 31 10:12:41 2026 +0000 fix(extension_manager): call initComponents() from parametrized constructor commit 90b140577d2b589130a60af2c293e6aac8e1855b Author: Pablo Iñigo Blasco Date: Tue Mar 31 12:11:22 2026 +0200 feat(extension_manager): add default constructor and initComponents() (#19) Enables dependency injection pattern for ExtensionManager: - Add default constructor for delayed initialization - Add initComponents() to set up downloader and load state - Parametrized constructor now calls initComponents() for consistency This allows creating an ExtensionManager instance first, then injecting dependencies later via initComponents(). commit 497c4d5f2f0b37c42ce475db2a9b7c530d805063 Merge: ce3a878 49ca22f Author: Pablo Iñigo Blasco Date: Tue Mar 31 00:03:37 2026 +0200 Merge branch 'feature/protoapp-multi-select-tree' into internal_main feat(protoapp): multi-select series tree for batch drag-and-drop commit ce3a878476558fcbec72dcc63fdb5be9400f0a96 Merge: bd1e11e 9b5b773 Author: Pablo Iñigo Blasco Date: Mon Mar 30 10:04:40 2026 +0000 Merge branch 'feat/extension-manager-injection' into 'internal_main' feat(extension_manager): add default constructor and initComponents() See merge request client-projets/p.2026-plotjuggler/plotjuggler_core!86 commit 9b5b773aadda50ecf6812ab780b3facee9cb4706 Author: Vlozano Date: Mon Mar 30 10:04:40 2026 +0000 feat(extension_manager): add default constructor and initComponents() commit 49ca22f0906ab649c6119c4aec0c4b120a0aa741 Author: Pmarin Date: Mon Mar 23 12:10:41 2026 +0100 feat(proto-app): multi-select series tree for batch drag-and-drop Allow selecting multiple fields in the left panel (Ctrl+click, Shift+click) and dropping them all onto the chart at once. - main_window: enable ExtendedSelection on the QTreeView - series_tree_model: mimeData() encodes all selected fields (count + N entries) instead of only the first one - chart_panel: dropEvent() decodes and adds N series in a single drop --- build.sh | 10 +++ .../pj_marketplace/extension_manager.hpp | 28 +++++++- .../pj_marketplace/marketplace_window.hpp | 6 ++ pj_marketplace/src/core/ExtensionManager.cpp | 70 ++++++++++++++++--- pj_marketplace/src/ui/marketplace_window.cpp | 27 ++++++- .../tests/extension_manager_test.cpp | 39 +++++++++++ pj_proto_app/src/chart_panel.cpp | 49 ++++++++++--- pj_proto_app/src/chart_panel.hpp | 5 ++ pj_proto_app/src/main_window.cpp | 8 ++- pj_proto_app/src/main_window.hpp | 4 ++ pj_proto_app/src/series_tree_model.cpp | 45 ++++++++---- 11 files changed, 251 insertions(+), 40 deletions(-) diff --git a/build.sh b/build.sh index 085545a..c1bd45a 100755 --- a/build.sh +++ b/build.sh @@ -59,6 +59,16 @@ build_config() { conan install "$SCRIPT_DIR" --output-folder="$build_dir" --build=missing \ -s build_type="$build_type" -s compiler.cppstd=20 \ "${conan_extra[@]+"${conan_extra[@]}"}" + + # Install dependencies from subdirectory conanfiles (e.g. pj_ported_plugins) + for sub_conan in "$SCRIPT_DIR"/pj_ported_plugins/conanfile.txt;

This allows dialogs to display a dynamic list of available parser encodings without requiring access to the RuntimeHost (which is bound after dialog closes). The encoding list is queried from PluginRegistry.listAvailableEncodings() and injected for both file sources (onLoadFile) and stream sources (onStartStream).

Plugins that publish colormaps receive the registry through a new optional bind_colormap_registry entry on the toolbox plugin vtable; the data-plane toolbox host no longer carries colormap-specific callbacks. pj_proto_app owns one ColorMapRegistry, threads it into each ToolboxSession, and feeds a live view to ChartPanel so registered maps take effect on the next refresh.

charset=UTF-8 Content-Transfer-Encoding: 8bit Protocol v3 replaces the per-service `bind__host` slots with a single `bind(registry, err)` entry point. All fallible ABI calls now carry a structured `PJ_error_t*` out-param (inline 304-byte struct with domain + message + growth-path `extended`/`extended_kind` slots). The three dedicated write-host vtables become services registered under canonical reverse-DNS names (`pj.source_write.v1`, `pj.parser_write.v1`, `pj.toolbox_host.v1`, `pj.runtime.v1`, `pj.toolbox_runtime.v1`, `pj.colormap.v1`). `get_dialog` returns a typed `PJ_borrowed_dialog_t` fat pointer instead of an untyped `void*`. Every family vtable shares the same 9-slot lifecycle prefix. On top of that, this commit lands the v3.1 hardening that locks down forward compatibility so future additive growth doesn't break existing plugins: E0 — Boot-level ABI symbol + min-vtable-size floor Every plugin .so exports `pj_plugin_abi_version` as a C symbol; loaders dlsym it before touching the vtable. Each family header defines `PJ__MIN_VTABLE_SIZE` (pinned at v3.0, never grows); loaders accept `struct_size >= MIN_SIZE` instead of `>= sizeof(host_struct)`, which would falsely reject plugins compiled against older headers. New tail slots are gated by `PJ_HAS_TAIL_SLOT(vtable_type, ptr, field)`. E1 — PJ_error_t growth path Appended `const void* extended` + `char extended_kind[32]` to PJ_error_t (struct grew from 260 B to 304 B). Future cause chains, stack traces, and structured payloads fit without a v4 break. `sdk::fillError` clears both new fields on every write to prevent stale-pointer reuse. Helpers `setExtended`/`hasExtended` added. E2 — CLAP-style plugin extension query Each family vtable grows a tail slot `const void* get_plugin_extension(ctx, id)`. SDK base classes expose `pluginExtension(std::string_view)` virtual; host handles expose `getPluginExtension(id)` with tail-slot gating. Mock toolbox advertises `pj.experimental.mock_diagnostics/draft-1` for integration testing. E3 — Compile-time ABI layout sentinels New `pj_base/tests/abi_layout_sentinels_test.cpp` pins sizeof/alignof/offsetof for every ABI-visible struct, enum sizes (defends against -fshort-enums), and `sizeof(void*) == 8`. A failing static_assert catches accidental field reorders in PRs. E4 — Compile-time service-name validation `detail::isValidServiceName` is constexpr; every trait's `kName` gets a static_assert. Enforces `"pj..v"` (stable) or `"pj.experimental./draft-"` (unstable) at definition site — no runtime string-parse on every registration. E5 — FROZEN vs APPENDABLE struct labels Header comments at every ABI-visible struct declare the policy. FROZEN = layout permanent (PJ_error_t, fat pointers, handles); APPENDABLE = tail slots may grow (all *_vtable_t types). E6 — Registry runtime hardening `ServiceRegistryBuilder::tryRegisterService` returns Expected; rejects null ctx/vtable and silent-overwrite duplicates. `dispatchGetService` null-checks before returning the fat pointer. Documentation: `pj_plugins/docs/ARCHITECTURE.md` gains a "§0a. ABI stability and evolution rules (v3.1)" section listing all seven rules plus the plugin-extension query contract. Tests that exercised the removed v1/v2 slots (data_source_plugin_base_test, message_parser_plugin_base_test, delegated_ingest_integration_test) are gated off in CMakeLists with TODO(v3-port) markers; coverage is retained by the integration-level *_library_test.cpp suite. --- pj_base/CMakeLists.txt | 8 +- .../include/pj_base/data_source_protocol.h | 206 +++++--- .../include/pj_base/message_parser_protocol.h | 84 ++-- pj_base/include/pj_base/plugin_data_api.h | 222 +++++++-- .../pj_base/sdk/data_source_host_views.hpp | 282 +++++++++++ .../pj_base/sdk/data_source_plugin_base.hpp | 469 ++++-------------- .../sdk/detail/data_source_trampolines.hpp | 122 ++--- .../sdk/detail/message_parser_trampolines.hpp | 83 ++-- .../sdk/detail/toolbox_trampolines.hpp | 104 ++-- .../sdk/message_parser_plugin_base.hpp | 120 ++--- .../include/pj_base/sdk/plugin_data_api.hpp | 366 +++++++++----- .../include/pj_base/sdk/service_registry.hpp | 118 +++++ .../include/pj_base/sdk/service_traits.hpp | 124 +++++ .../pj_base/sdk/toolbox_plugin_base.hpp | 234 ++++----- pj_base/include/pj_base/toolbox_protocol.h | 127 ++--- pj_base/tests/abi_layout_sentinels_test.cpp | 98 ++++ pj_datastore/src/colormap_registry_host.cpp | 15 +- pj_datastore/src/plugin_data_host.cpp | 227 ++++++--- pj_plugins/CMakeLists.txt | 27 +- pj_plugins/dialog_protocol/CMakeLists.txt | 3 +- .../include/pj_plugins/dialog_protocol.h | 47 +- .../include/pj_plugins/host/dialog_handle.hpp | 46 +- .../pj_plugins/sdk/dialog_plugin_base.hpp | 155 +++--- .../tests/dialog_handle_test.cpp | 7 - .../tests/plugin_lifecycle_test.cpp | 38 +- pj_plugins/docs/ARCHITECTURE.md | 112 +++++ .../examples/mock_source_with_dialog.cpp | 10 +- pj_plugins/examples/mock_toolbox.cpp | 33 +- .../pj_plugins/host/data_source_handle.hpp | 129 +++-- .../pj_plugins/host/message_parser_handle.hpp | 78 +-- .../host/service_registry_builder.hpp | 160 ++++++ .../pj_plugins/host/toolbox_handle.hpp | 96 ++-- pj_plugins/src/data_source_library.cpp | 11 +- pj_plugins/src/detail/library_loader.hpp | 17 + pj_plugins/src/message_parser_library.cpp | 9 +- pj_plugins/src/toolbox_library.cpp | 9 +- pj_plugins/tests/data_source_library_test.cpp | 270 ++++------ .../tests/file_source_integration_test.cpp | 120 +++-- .../tests/message_parser_library_test.cpp | 93 ++-- .../tests/source_dialog_integration_test.cpp | 22 +- pj_plugins/tests/toolbox_plugin_test.cpp | 301 ++++------- pj_proto_app/src/data_source_session.cpp | 103 ++-- pj_proto_app/src/data_source_session.hpp | 25 +- pj_proto_app/src/main_window.cpp | 18 +- pj_proto_app/src/toolbox_session.cpp | 82 +-- pj_proto_app/src/toolbox_session.hpp | 13 +- 46 files changed, 2963 insertions(+), 2080 deletions(-) create mode 100644 pj_base/include/pj_base/sdk/data_source_host_views.hpp create mode 100644 pj_base/include/pj_base/sdk/service_registry.hpp create mode 100644 pj_base/include/pj_base/sdk/service_traits.hpp create mode 100644 pj_base/tests/abi_layout_sentinels_test.cpp create mode 100644 pj_plugins/include/pj_plugins/host/service_registry_builder.hpp diff --git a/pj_base/CMakeLists.txt b/pj_base/CMakeLists.txt index dd30540..d37c8d5 100644 --- a/pj_base/CMakeLists.txt +++ b/pj_base/CMakeLists.txt @@ -45,8 +45,12 @@ if(PJ_BUILD_TESTS) tests/expected_test.cpp tests/plugin_data_api_test.cpp tests/data_source_protocol_test.cpp - tests/data_source_plugin_base_test.cpp - tests/message_parser_plugin_base_test.cpp + # TODO(v3-port): data_source_plugin_base_test.cpp and + # message_parser_plugin_base_test.cpp exercise old bind_write_host / + # bind_runtime_host slots removed in v3.

ABI stability and evolution rules (v3.1) + +Seven rules the loader and every plugin author rely on. Breaking any of +these is an ABI break and requires a v4 bump. + +1. **Boot-level ABI symbol.** Every plugin .so exports + `pj_plugin_abi_version` as a `const uint32_t` symbol independent of + any vtable. The host `dlsym`s it BEFORE fetching the family vtable; + missing or mismatched symbol is a fail-fast rejection with a specific + error. Emitted automatically by `PJ_DATA_SOURCE_PLUGIN`, + `PJ_MESSAGE_PARSER_PLUGIN`, `PJ_TOOLBOX_PLUGIN` macros. Current value + is `PJ_ABI_VERSION == 3`. + +2. **Min-vtable-size floor, pinned at v3.0.** Each family header defines + `PJ__MIN_VTABLE_SIZE` — the byte count of the vtable as + shipped in v3.0. The loader accepts + `struct_size >= MIN_VTABLE_SIZE`. This constant MUST NEVER GROW. + Growing it would reject plugins compiled against older v3 headers + (which correctly report a smaller size), silently breaking the + forward-compatibility promise. + +3. **Tail-slot gating.** Every vtable slot added after v3.0 is a tail + slot. Host reads must go through the `PJ_HAS_TAIL_SLOT(vtable_type, + vtable_ptr, field)` macro, which verifies both that the plugin's + `struct_size` reaches the slot AND that the slot is non-null. Skipping + this gate is undefined behaviour on plugins built against older + headers. + +4. **Frozen vs appendable struct classification.** Each ABI-visible + struct carries a header comment declaring its policy: + - **ABI-FROZEN**: `PJ_error_t`, `PJ_string_view_t`, `PJ_bytes_view_t`, + `PJ_borrowed_dialog_t`, `PJ_service_t`, `PJ_service_registry_t`, + handle types, primitive-value unions. Layout permanent; any change + is a v4 break. `PJ_error_t` has `extended` + `extended_kind` slots + reserved as its one growth path — do not add further top-level + fields. + - **ABI-APPENDABLE**: all `*_vtable_t` types, service-host vtables, + `PJ_service_registry_vtable_t`. New slots at the tail; read with + `PJ_HAS_TAIL_SLOT`. + +5. **Compile-time ABI layout sentinels.** `pj_base/tests/abi_layout_sentinels_test.cpp` + consists entirely of `static_assert`s pinning `sizeof`, `alignof`, + and `offsetof` for every ABI struct plus `sizeof(void*)` (64-bit + guard) and enum-size pins (defends against `-fshort-enums`). A + failed assertion at compile time is ALWAYS a serious signal: + - Offset changes = field reorder = ABI break. + - MIN-size increase = floor moved = forward-compat break. + - sizeof growth = deliberate append, update the assertion. + +6. **Service-name grammar (compile-time enforced).** + | Pattern | Stability | + |---|---| + | `"pj..v"` | Stable. Frozen for ≥3 releases before deprecation. | + | `"pj.experimental./draft-"` | Unstable. No guarantees. | + `sdk/service_traits.hpp` calls `detail::isValidServiceName()` in a + `static_assert` at every trait's `kName`. Requesting a + `pj.experimental.*` service should log a runtime warning through the + `pj.runtime.v1` log channel. + +7. **Exception discipline at the ABI boundary.** Every C ABI entry + point (SDK trampolines and host-side service trampolines) must + catch all exceptions and convert to a `PJ_error_t` out-param (or a + safe default for non-fallible calls). C++ exceptions across + `dlopen` boundaries are undefined behaviour in practice. The + `data_source_trampolines.hpp` / `message_parser_trampolines.hpp` / + `toolbox_trampolines.hpp` files centralize this pattern — mirror it + exactly in any new trampoline. + +### Plugin extension query (CLAP-style, v3.1) + +Each family vtable has a tail slot +`const void* (*get_plugin_extension)(void* ctx, PJ_string_view_t id)` +that plugins use to expose additional capabilities to the host without +bumping the family protocol version. The plugin returns a static POD +for known ids or `nullptr`. Hosts call via `handle.getPluginExtension(id)` +(tail-slot-gated). Use the experimental namespace for work-in-progress +extensions; graduate to stable (`pj..v1`) once locked in. + +## 0. Protocol v3 (current) + +All four plugin families (DataSource, MessageParser, Toolbox, Dialog) have +been migrated to protocol v3. The key structural changes from v1/v2: + +- **Service registry as the sole binding mechanism.** Plugin vtables expose + a single `bind(ctx, registry, err)` slot. The host registers all services + (write hosts, runtime hosts, colormap, etc.) under canonical + reverse-DNS-style names (e.g. `"pj.source_write.v1"`, + `"pj.runtime.v1"`, `"pj.toolbox_runtime.v1"`, `"pj.colormap.v1"`). Plugins + acquire only the services they use. +- **Structured errors everywhere.** All fallible ABI calls take a + `PJ_error_t* out_error` out-parameter. The old per-plugin `get_last_error` + slot is gone. +- **Unified write surface.** The three previous write-host vtables + (`PJ_source_write_host_vtable_t`, `PJ_parser_write_host_vtable_t`, + `PJ_toolbox_host_vtable_t`) collapse into one `PJ_write_surface_vtable_t`. + Service name selects semantics; host implementations enforce scope. + Three SDK facade views (`SourceWriteHostView`, `ParserWriteHostView`, + `ToolboxHostView`) still present family-appropriate APIs at the C++ level. +- **Typed borrowed dialog.** `get_dialog_context()` returning `void*` is + replaced by `get_dialog()` returning a `PJ_borrowed_dialog_t` fat pointer + `{ctx, const PJ_dialog_vtable_t* vtable}`. +- **Uniform plugin-vtable prefix.** Every family vtable starts with + `protocol_version, struct_size, create, destroy, manifest_json, + capabilities, bind, save_config, load_config` in that order. Host-side + generic code can iterate all families through a common header layout. + +Service traits (`pj_base/sdk/service_traits.hpp`, +`sdk/toolbox_plugin_base.hpp`) map canonical names to their ABI type and +C++ view. `PJ::ServiceRegistryBuilder` (`pj_plugins/host/`) is the +host-side assembler that populates a `PJ_service_registry_t` from +registered services. + ## 1.

Double bind() on DataSource plugins. DataSourceSession::bindRuntimeHostForDialog() was binding a runtime-only registry before the dialog, and setupAndStart() was rebinding the full registry afterward — calling bind() twice per plugin instance. The v3 protocol requires bind() to be one-shot. Fixed by creating the dataset + write host up-front in a new DataSourceSession::bindForDialog() method, so the full registry (source_write + runtime) is ready before the dialog is shown. Renamed setupAndStart() → applyConfigAndStart() to reflect that it no longer binds; added an idempotency guard (bound_ flag) so a second call is a no-op. Side-effect: an empty dataset remains if the user cancels the dialog — acceptable for now, documented inline. Updated call sites in main_window.cpp (onLoadFile, onStartStream, startDummyStream, restartSession). 2. Toolbox service name mismatch. service_traits.hpp defined ToolboxHostService::kName as "pj.toolbox_host.v1" but every doc and comment referenced "pj.toolbox_write.v1" — the name used for consistency with "pj.source_write.v1" and "pj.parser_write.v1". Renamed to match the docs; the C++ trait keeps its historical name because the underlying vtable type is PJ_toolbox_host_t. 3. DialogPluginBase::storeError left v3.1 growth slots uncleared. The local storeError() helper in dialog_plugin_base.hpp set code/domain/message via a writeField lambda but did not reset the new extended / extended_kind slots added in v3.1. A reused PJ_error_t struct could therefore carry a stale extended pointer across calls. Fixed by clearing both slots, matching the sdk::fillError discipline. All 38 non-ASAN-incompatible tests pass. --- .../include/pj_base/sdk/service_traits.hpp | 8 +- .../pj_plugins/sdk/dialog_plugin_base.hpp | 4 + pj_proto_app/src/data_source_session.cpp | 81 ++++++++++--------- pj_proto_app/src/data_source_session.hpp | 15 +++- pj_proto_app/src/main_window.cpp | 24 +++++- 5 files changed, 87 insertions(+), 45 deletions(-) diff --git a/pj_base/include/pj_base/sdk/service_traits.hpp b/pj_base/include/pj_base/sdk/service_traits.hpp index e3ac546..99027b0 100644 --- a/pj_base/include/pj_base/sdk/service_traits.hpp +++ b/pj_base/include/pj_base/sdk/service_traits.hpp @@ -93,7 +93,13 @@ struct ParserWriteHostService { }; struct ToolboxHostService { - static constexpr const char* kName = "pj.toolbox_host.v1"; + // "pj.toolbox_write.v1" for symmetry with "pj.source_write.v1" and + // "pj.parser_write.v1" — this service IS the toolbox write surface + // (create_data_source / ensure_topic / ensure_field / append_record / + // acquire_catalog_snapshot / read_series).

Data-plane changes (pj_base/plugin_data_api.h): * Inlined Arrow C Data Interface POD types (ArrowSchema / ArrowArray / ArrowArrayStream) under the standard ARROW_C_DATA_INTERFACE guard. * SourceWriteHost and ToolboxHost: append_arrow_ipc REMOVED, replaced with append_arrow_stream (producer-owned release, pull-model ingest). * ToolboxHost: read_series + PJ_materialized_series_t REMOVED, replaced with read_series_arrow (host-owned ArrowSchema + ArrowArray). * ParserWriteHost: append_arrow_ipc REMOVED (parsers are per-record; host coalesces internally). ABI hardening: * Every vtable slot is now PJ_NOEXCEPT (C++17 type-level noexcept, no-op in C). Trampolines that drop exceptions through the ABI now terminate the plugin deterministically instead of unwinding. * Every slot carries a thread-class tag: [main-thread], [stream-thread], [thread-safe]. * PJ_ABI_VERSION bumped 3 -> 4. Per-family PROTOCOL_VERSION bumped 3 -> 4. * MIN_VTABLE_SIZE re-pinned at v4.0 (get_plugin_extension is now part of the baseline, no longer a tail slot). SDK updates (pj_base/sdk/*): * All four base classes (DataSourcePluginBase, MessageParserPluginBase, ToolboxPluginBase, DialogPluginBase) + their detail/*_trampolines.hpp thunks updated to noexcept. * PJ_*_PLUGIN macros emit noexcept on PJ_get_*_vtable entry points. * SourceWriteHostView / ToolboxHostView: - appendArrowIpc replaced with appendArrowStream (ownership- transfer on success). - readSeries replaced with readSeriesArrow (caller-owned Arrow structs). * ParserWriteHostView: appendArrowIpc removed. Host-side (pj_datastore/src/plugin_data_host.cpp): * Stubbed implementations of append_arrow_stream and read_series_arrow return a clear "not yet implemented (Phase 1b)" error. The real nanoarrow-backed implementations land in Phase 1b. * All trampolines noexcept. * Dropped MaterializedSeriesState and its 200-line readSeries method. Verification: * abi_layout_sentinels_test updated with v4 offsets/sizes. MIN floors now at v4.0: DataSource=128, MessageParser=80, Toolbox=88. * Release build: 60/60 tests pass. * Debug+ASAN build: 36/41 pass; the 5 failures are the pre-existing RTLD_DEEPBIND + ASAN dlopen incompatibilities (fixed in Phase 1d). * plugin_host_write_test and plugin_host_read_test disabled in CMake pending Phase 1b (they exercise the v3 materialised-vector read path that no longer exists at the ABI). ABI_migration_PLAN.md retires in Phase 3.

No functional change for the IPC path; shared code path guarantees the two stay in sync. * Factored schema-parsing logic into a private mappingsFromSchema helper. schemaFromIpc and the new schemaFromArrowStream both use it. * New public entry points: importArrowStream(writer, topic, stream, mappings, ts_col) schemaFromArrowStream(stream) Both preserve caller-side ownership of the stream — the importer never calls stream->release. Host-side wiring (plugin_data_host.cpp): * WriteCore::appendArrowStream replaces the old appendArrowIpc. * ToolboxCore::readSeriesArrow materialises one field's time series into a host-owned struct ArrowArray with two columns: ["timestamp" (int64), (typed)]. Built via nanoarrow. Supports all primitive types including strings. * sourceAppendArrowStream / toolboxAppendArrowStream trampolines now enforce the ABI ownership contract: on success the host calls stream->release before returning; on failure the plugin retains responsibility. Test (new): * arrow_stream_round_trip_test — end-to-end round trip through the v4 ABI. Builds an in-memory ArrowArrayStream, feeds it through append_arrow_stream, reads back via read_series_arrow, compares values exactly. Confirms schema shape and release-callback hygiene. Verification: * Release build: 60/60 tests pass. * Debug+ASAN: 37/42 pass (new round-trip test added and green). The 5 failures are the pre-existing RTLD_DEEPBIND + ASAN dlopen incompatibilities (Phase 1d fixes them).

Arrow C Data Interface RAII holders (pj_base/sdk/arrow.hpp). Move-only wrappers around the three Arrow C Data Interface POD types declared in the ABI header (ArrowSchema, ArrowArray, ArrowArrayStream). Each holder calls release on destruction iff release != nullptr. Makes the common "produce -> hand to host -> release" and "receive from host -> use -> release" patterns exception-safe and terse: ArrowSchemaHolder schema; ArrowArrayHolder array; auto s = toolbox.readSeriesArrow(field, schema.out(), array.out()); // schema/array auto-release at scope exit Zero-dep: stdlib only. Plugins that want richer Arrow builders link nanoarrow themselves. New test arrow_holders_test verifies destructor/move/reset/out/release semantics plus the post-host-takes-ownership inert path. 2. Plugin manifest sidecar emission (cmake/PjPluginManifest.cmake). CMake function pj_emit_plugin_manifest(target FAMILY [MANIFEST_FILE ] [ABI_MAJOR ]) reads the plugin's existing manifest.json (the same file pj_embed_manifest bakes into the DSO), augments it with auto-generated "abi_major" and "family" keys, and writes a sidecar .pjmanifest.json next to the built DSO and at install time. Lets a host scan all installed plugins at startup without dlopen'ing any — essential at the 20-50 plugin target scale. The DSO manifest is still the source of truth; host-side scanning will (Phase 1d) verify sidecar vs DSO on activation and fall back to DSO on mismatch. Root CMakeLists.txt now prepends cmake/ to CMAKE_MODULE_PATH and unconditionally includes the helper, so plugins just call the function without boilerplate include lines. Verification: * Release build: 60/60 tests pass. * Debug+ASAN: 38/43 pass (new arrow_holders_test green; same 5 pre-existing RTLD_DEEPBIND failures to be fixed in Phase 1d). * Verified sidecar emission end-to-end: data_load_csv_plugin writes csv_source_plugin.pjmanifest.json with abi_major=4 and family="data_source" injected on top of the plugin's existing manifest.json content. (The CMake wiring of the CSV plugin lives in the pj_ported_plugins repo; committed there separately.)

charset=UTF-8 Content-Transfer-Encoding: 8bit Two Phase 1d deliverables: 1. Loader hardening: drop RTLD_DEEPBIND (pj_plugins/src/detail/library_loader.hpp) The v3 loader set RTLD_NOW | RTLD_LOCAL | RTLD_DEEPBIND on glibc. DEEPBIND is a documented AddressSanitizer trap — ASAN flat-out refuses to dlopen anything with DEEPBIND because it bypasses LD_PRELOAD'd malloc interposition (same issue with jemalloc/ tcmalloc/mimalloc in production). That cost us all five pre-existing debug+ASAN failures. Dropping DEEPBIND fixes them. Plugin-local symbol isolation is instead left to -fvisibility=hidden on plugin builds, to be enforced when each plugin is ported. 2. Sidecar-based plugin discovery (plugin_catalog.hpp + plugin_catalog.cpp). New public API: PJ::scanPluginSidecars(directory) -> Expected> Scans a directory non-recursively for *.pjmanifest.json files, decodes each into a typed PluginDescriptor (name, version, abi_major, family, description, category, encoding, file_extensions, capabilities, sidecar_path, dso_path), and returns them sorted. Malformed sidecars are skipped silently. Uses nlohmann_json. Zero dlopen — the whole point of sidecar discovery. Companion to pj_emit_plugin_manifest (Phase 1c): CMake writes the sidecars at build time; scanPluginSidecars reads them at startup. Test plugin_catalog_test exercises eight cases: missing directory, empty directory, valid sidecar round-trip, malformed JSON skipped, missing required keys skipped, unknown family skipped, non-sidecar files ignored, sorted output, family toString round-trip. Verification: * Release build: 60/60 tests pass. * Debug+ASAN: 44/44 tests pass — the 5 pre-existing data_source_library_test / source_dialog_integration_test / file_source_integration_test / message_parser_library_test / toolbox_plugin_test failures that survived v3.1 are now GREEN.

charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 2 is "port plugins to v4." On core-side (plotjuggler_core) the work is scaffolding: - plugin_catalog_test gains an optional integration test that, when PJ_BUILD_PORTED_PLUGINS is on, scans the build-tree output directory for the 4 file-source plugin sidecars produced by pj_emit_plugin_manifest and verifies every entry parses cleanly with abi_major==4 and a known family. Closes the loop end-to-end: CMake emits sidecars on build, scanner reads them at test time. - CMake wires the test with a generator-expression sidecar dir and depends on the four plugin targets so the sidecars exist by the time the test runs. Plus one cleanup, flagged as "not an official version": - pj_base/CMakeLists.txt: drop the stale TODO(v3-port) tag. The two retired unit tests (data_source_plugin_base_test, message_parser_plugin_base_test) exercised ABI slots that are long gone; the service-registry-era coverage lives in the *_library_test.cpp integration tests. Either rewrite or delete them — noted but not tackled here. The plugin-side edits (pj_emit_plugin_manifest calls in data_load_mcap, data_load_parquet, data_load_ulog; and the v3-era comment in pj_ported_plugins/CMakeLists.txt) live in the pj_official_plugins repo and are committed separately. Verification: release 60/60, debug+ASAN 44/44. Integration test proves the catalog scanner successfully parses the sidecars emitted by the four v4-ready file-source plugins.

All four plugin author guides gain a short "> Tracks the v4 plugin ABI" callout at the top pointing readers to ARCHITECTURE.md as the binding reference. The bodies of the guides still have some v1/v2-era lifecycle prose (bind_write_host, bind_runtime_host) that describes the old design; those sections are historical context and need rewriting in a separate author-ergonomics pass. The four reference plugins (data_load_csv, data_load_mcap, data_load_parquet, data_load_ulog) are the working v4 examples. Also retires the scratch ABI_migration_PLAN.md at the repo root — it was superseded by this whole v4 effort. Verification: release 60/60, debug+ASAN 44/44.

Components: * cmake/PjAbiCheck.cmake — opt-in via -DPJ_ENABLE_ABI_CHECK=ON. Emits two targets: abi_check run abidiff baseline.abi vs current DSO abi_update_baseline regenerate baseline (intentional ABI change) Also registers abi_check_test with CTest so it runs as part of the normal ./test.sh flow when the option is on. * cmake/PjAbiCheckRun.cmake — interprets abidiff exit-bit mask: bit 0/1 (tool/user error) hard fail bit 4 (compatible change) warn + continue bit 8 (INCOMPATIBLE change) hard fail Warnings carry a pointer to the abi_update_baseline target so refreshing is one command. * pj_base/abi/baseline.abi — XML snapshot of the v4.0 ABI surface from libmock_data_source_plugin.so, filtered to types reachable from pj_base/include via --headers-dir. Exempted from the check-added-large-files pre-commit hook (it's an intentional reference artifact, ~1.1 MB). * Top-level CMakeLists.txt adds PJ_ENABLE_ABI_CHECK (default OFF) and includes the helper after all targets are defined. Verified: * abi_check passes on the current tree (exit 0, no drift). * Simulated drift correctly produces a bit-4 warning. * debug+ASAN: 45/45 (new abi_check_test green).

Arrow C Data Interface reality MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The v4 merge replaced append_arrow_ipc with append_arrow_stream on the source and toolbox write hosts, dropped the Arrow slot from parsers entirely, and added read_series_arrow + the ArrowSchemaHolder / ArrowArrayHolder / ArrowStreamHolder RAII wrappers — but the prose in the plugin guides still showed the old appendArrowIpc/readSeries names. This sweep: - Fixes every remaining appendArrowIpc / readSeries reference in the four SDK tutorials and REQUIREMENTS.md. - Adds a worked readSeriesArrow example to toolbox-guide.md and a worked appendArrowStream example (with ownership-transfer dance) to data-source-guide.md. - Rewrites the parser-guide Arrow section as an explicit 'per-record only; redirect bulk flows to DataSource' note. - Documents the Arrow-at-boundary ownership contract, the manifest sidecar format + pj_emit_plugin_manifest CMake helper, and the abidiff drift gate as new subsections in ARCHITECTURE.md. - Clarifies that MaterializedSeries is a host-internal C++ type on DatastoreToolboxHost, not part of the ABI surface.

Owns both holders (move-only), decodes the Arrow format string into PJ::PrimitiveType, exposes timestamps() as Span aliasing the Arrow buffer, and a family of valuesAs{Float64,Float32,Int32,...}() typed pointer accessors that return nullptr on type mismatch. Also adds ToolboxHostView::readSeries(field) as a convenience wrapper that calls the raw readSeriesArrow slot and returns the view. This gives toolbox plugins a near-drop-in replacement for the pre-v4 'series->timestamps() + series->raw().values.as_float64' API — the port ends up as a ~2-line find/replace per readSeries call rather than a full Arrow-walk rewrite.

This pass: - Replaces dialogContext()/void*-returning getters with the new PJ_borrowed_dialog_t getDialog() override + PJ::borrowDialog(dialog_) helper across data-source-guide, toolbox-guide, dialog-plugin-guide, REQUIREMENTS.md and ARCHITECTURE.md. - Updates Arrow-bulk-write examples (data-source-guide, toolbox-guide) to use the new rvalue-ref overload — std::move(stream) — instead of the manual (void)stream.release() after success pattern. - Adds Testing sections to toolbox-guide and message-parser-guide pointing plugin authors at ToolboxTestStore / ParserWriteRecorder so unit tests no longer hand-roll Arrow C Data Interface or host-vtable plumbing. All prose examples now compile mentally against the actual current SDK surface. The one remaining 'appendArrowIpc' reference in message-parser-guide is an intentional negation ('no appendArrowIpc slot on parser write host') kept for documentation value. --- pj_plugins/docs/ARCHITECTURE.md | 3 +- pj_plugins/docs/REQUIREMENTS.md | 3 +- pj_plugins/docs/data-source-guide.md | 61 ++++++++++---------- pj_plugins/docs/dialog-plugin-guide.md | 17 +++++- pj_plugins/docs/message-parser-guide.md | 34 ++++++++++- pj_plugins/docs/toolbox-guide.md | 75 +++++++++++++++++++++---- 6 files changed, 146 insertions(+), 47 deletions(-) diff --git a/pj_plugins/docs/ARCHITECTURE.md b/pj_plugins/docs/ARCHITECTURE.md index 387ef7c..a006393 100644 --- a/pj_plugins/docs/ARCHITECTURE.md +++ b/pj_plugins/docs/ARCHITECTURE.md @@ -318,7 +318,8 @@ Each family has a move-only RAII handle: **Borrowed handles:** `DialogHandle` supports a `borrowed()` factory for dialogs that are members of another plugin (e.g. a DataSource's dialog).

Each host capability is a named service resolved at +`bind(services)` time: + +| Service name | Consumer | Purpose | +|---|---|---| +| `pj.source_write.v1` | DataSource | scalar write, multi-topic | +| `pj.parser_write.v1` | MessageParser | scalar write, **topic-scoped** (one per parser instance) | +| `pj.toolbox_write.v1` | Toolbox | scalar read + write + catalog + `readSeriesArrow` | +| `pj.runtime.v1` | DataSource | progress, parser binding, raw dispatch | +| `pj.toolbox_runtime.v1` | Toolbox | message reporting, notifyDataChanged | +| `pj.colormap.v1` | Toolbox | optional, colormap registry | + +Host-side plumbing lives in `pj_datastore/src/plugin_data_host.cpp` +(vtable builders + trampolines). Service trait structs live in +`pj_base/include/pj_base/sdk/service_traits.hpp`. SDK views live in +`pj_base/include/pj_base/sdk/plugin_data_api.hpp` and +`data_source_host_views.hpp`. + +### Prerequisites (already rebased into the working branch) + +The datastore-side pieces are already present on the current branch +(rebased from `media_implementation`): + +- `pj_datastore/include/pj_datastore/object_store.hpp` +- `pj_datastore/src/object_store.cpp` +- `pj_datastore/tests/object_store_test.cpp` +- `pj_datastore/docs/OBJECT_STORE_DESIGN.md` + +Plugin-boundary work starts directly from here — no branch or rebase +step is pending. + +--- + +## Design decision: compose, don't break + +The `OBJECT_STORE_DESIGN.md §6` and `pj_media/docs/REQUIREMENTS.md` +Prerequisites were written assuming a pre-v4 mental model, where +parsers receive a single write host bound at setup. They therefore +frame the "two-host parse()" requirement as an **ABI-breaking v2 bump**. + +With v4's service registry in place, that framing is wrong. We can +deliver the same contract without bumping the parser protocol version: + +**Add the object write host as a second, optional, topic-scoped +service** that parsers resolve alongside the scalar write host: + +- `pj.parser_write.v1` — unchanged, topic-scoped scalar write. +- `pj.parser_object_write.v1` — **new**, topic-scoped object write, + registered by the host only when the parser is bound to a media topic. + +The parser's `parse()` signature does not change. A media-capable parser +overrides `bind()` to resolve both services (`require()` + +`require()` — or `optional()` for +dual-purpose parsers). A scalar-only parser resolves only the scalar +service and keeps working unchanged. **No ABI break**, **no protocol +bump**, **no signature change**. + +This applies the same asymmetry we already use for `pj.colormap.v1` (an +optional service resolved opportunistically by toolboxes that want it). + +--- + +## Phases + +Sequenced so each phase compiles and tests independently. Each phase is +committable on its own. + +### Phase 1 — DataSource object write host (`pj.source_object_write.v1`) + +**Goal:** let a DataSource plugin register object topics and push owned +or lazy payloads.

Same pattern as the + existing `TopicHandle` / `FieldHandle`. +- **`pushLazy(Fetch&&)` helper** (phase 1) and + **`pushOwned(std::vector&&)` rvalue overload** — move into + the store on the C++ side when we can, fall back to copy on the C + ABI slot.

Prevents typos that would break viewer auto-routing. + +### Phase 5 — Toolbox object write (transformer plugins, future) + +Deferred. Once transformer plugins become real, add +`pj.toolbox_object_write.v1` reusing the same +`PJ_object_write_host_vtable_t`. All plumbing patterns from phase 1 +apply. + +Not scoped in this plan; noted so reviewers know the shape. + +### Phase 6 — MCAP plugin demonstration + +Once phases 1–4 land, port the MCAP plugin (on `pj_official_plugins`) +to the new surface. Four internal modes: + +1. **Scalar topics** — existing delegated parser binding, unchanged. +2. **Small-message topics (eager)** — e.g. + `visualization_msgs/Marker`, ImageAnnotation, scene primitives. + - At file open: register one object topic per channel with + `MediaMetadataBuilder`. + - Per message: `pushOwned(handle, ts_ns, bytes)` — the store + takes ownership of the serialized payload. No fetch closure, no + shared-reader bookkeeping. +3. **Large-blob topics (lazy)** — still images, point clouds. + - At file open: register one object topic per channel. + - Per message: `pushLazy` with a closure capturing + `{shared_ptr, message.data_offset, + message.data_size}`. +4. **Shared topics** (e.g., `sensor_msgs/CompressedImage` with scalar + `header.seq` + bytes): delegated ingest with a CDR parser that + resolves both `pj.parser_write.v1` and `pj.parser_object_write.v1`, + writes `header.seq` to the former and JPEG bytes to the latter — from + a single `parse()` call.

Matches existing v4 naming discipline. +2. **Keyframe index + video topics.** Both deferred entirely. + `publish_keyframe_index` is out of the vtable, and video topics are + skipped by the MCAP port. Keyframe indexing is a special case of a + more general auxiliary-index mechanism that deserves its own + design; delivering only storage for video without decode/seek would + be a half-wired feature.

From 79e3868dc51ce8ac155b1dad181dc5d10c884405 Mon Sep 17 00:00:00 2001 From: Davide Faconti Date: Wed, 22 Apr 2026 22:12:14 +0200 Subject: [PATCH 149/168] =?UTF-8?q?feat(v4=20ABI):=20phase=201=20=E2=80=94?= =?UTF-8?q?=20source=20object=20write=20host?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the plugin-visible surface for DataSource plugins to write into ObjectStore alongside the existing scalar write host. Composed via the v4 service registry as an optional service — no ABI break, no protocol bump, scalar-only plugins unaffected. New surface: - C ABI: PJ_object_topic_handle_t, PJ_lazy_fetch_fn_t, PJ_object_write_host_vtable_t, PJ_object_write_host_t. - Service trait: SourceObjectWriteHostService -> "pj.source_object_write.v1". - SDK view: sdk::SourceObjectWriteHostView with registerTopic / pushOwned / pushLazy / setRetentionBudget. pushLazy(Fetch&&) hides the fetch_ctx / fetch_ctx_destroy ABI dance behind a C++ lambda via a heap-allocated move-capture box. - DataSourcePluginBase::bind() resolves the service optionally; objectWriteHost() returns nullptr on hosts that don't register it. - Host plumbing: DatastoreSourceObjectWriteHost(ObjectStore&, DatasetId) in pj_datastore, with trampolines that wrap the C-ABI fetch callback in a shared_ptr so fetch_ctx_destroy runs exactly once when ObjectStore drops the entry. Tests: 9 new cases in plugin_data_host_object_test covering register/ push_owned/push_lazy/retention/invalid-topic/unbound-view paths plus an explicit destroy-callback exact-once verification via the raw C ABI. 67/67 ctest green under Debug+ASAN. --- pj_base/include/pj_base/plugin_data_api.h | 84 +++++++ .../pj_base/sdk/data_source_plugin_base.hpp | 22 +- .../include/pj_base/sdk/plugin_data_api.hpp | 135 ++++++++++++ .../include/pj_base/sdk/service_traits.hpp | 13 ++ pj_datastore/CMakeLists.txt | 1 + .../include/pj_datastore/plugin_data_host.hpp | 23 ++ pj_datastore/src/plugin_data_host.cpp | 180 +++++++++++++++ .../tests/plugin_data_host_object_test.cpp | 206 ++++++++++++++++++ 8 files changed, 662 insertions(+), 2 deletions(-) create mode 100644 pj_datastore/tests/plugin_data_host_object_test.cpp diff --git a/pj_base/include/pj_base/plugin_data_api.h b/pj_base/include/pj_base/plugin_data_api.h index 1a51300..a789b9b 100644 --- a/pj_base/include/pj_base/plugin_data_api.h +++ b/pj_base/include/pj_base/plugin_data_api.h @@ -470,6 +470,90 @@ typedef struct { const PJ_toolbox_host_vtable_t* vtable; } PJ_toolbox_host_t; +/* ========================================================================== + * Object-store write host (protocol v4) + * + * Plugin-visible surface over `pj_datastore::ObjectStore` — a message- + * oriented peer to DataEngine holding timestamped opaque payloads + * (markers/annotations written eagerly via push_owned; images/point + * clouds written lazily via push_lazy with a plugin-owned fetch closure). + * + * Separate from the scalar write surface by design: a plugin family + * may want one, the other, or both.

Keeps each capability on its own service so transformer-style plugins (read bytes, emit results) that don't need scalar read/write can resolve only what they care about. Read path uses an opaque owning-handle model that mirrors `shared_ptr>`: - C ABI: PJ_object_bytes_handle_t (opaque forward-declared pointer), PJ_object_read_host_vtable_t with lookup_topic / list_topics / topic_metadata / read_latest_at / get_bytes / release_bytes / entry_count / time_range. get_bytes / release_bytes take the handle directly (no ctx) — the handle carries its own state. - SDK: PJ::sdk::ObjectBytes move-only RAII wrapper that calls release_bytes in its destructor. Usable across worker threads because the handle keeps bytes alive independent of the store. - Service trait: ToolboxObjectReadHostService. - SDK view: ToolboxObjectReadHostView with lookupTopic / listTopics / topicMetadata / readLatestAt / entryCount / timeRange. listTopics does a two-call resize dance matching the C ABI. - ToolboxPluginBase::bind() resolves the service optionally; objectReadHost() returns nullptr when the host doesn't register it. - Host plumbing: DatastoreToolboxObjectReadHost allocates an ObjectBytesBox (holding the shared_ptr) per successful read_latest_at, freed by release_bytes. Tests: 11 new cases - read-after-write, destructor exact-once, owning-handle-survives-eviction, lookup/list/metadata round-trip, time_range, read-miss, cross-thread handle move, unbound-view fallbacks, moved-from-holder is empty. 68/68 ctest green under Debug+ASAN. --- pj_base/include/pj_base/plugin_data_api.h | 74 +++++++ pj_base/include/pj_base/sdk/object_bytes.hpp | 88 ++++++++ .../include/pj_base/sdk/plugin_data_api.hpp | 112 ++++++++++ .../include/pj_base/sdk/service_traits.hpp | 14 ++ .../pj_base/sdk/toolbox_plugin_base.hpp | 20 +- pj_datastore/CMakeLists.txt | 1 + .../include/pj_datastore/plugin_data_host.hpp | 22 ++ pj_datastore/src/plugin_data_host.cpp | 187 +++++++++++++++++ .../plugin_data_host_object_read_test.cpp | 196 ++++++++++++++++++ 9 files changed, 711 insertions(+), 3 deletions(-) create mode 100644 pj_base/include/pj_base/sdk/object_bytes.hpp create mode 100644 pj_datastore/tests/plugin_data_host_object_read_test.cpp diff --git a/pj_base/include/pj_base/plugin_data_api.h b/pj_base/include/pj_base/plugin_data_api.h index a789b9b..66d5513 100644 --- a/pj_base/include/pj_base/plugin_data_api.h +++ b/pj_base/include/pj_base/plugin_data_api.h @@ -554,6 +554,80 @@ typedef struct { const PJ_object_write_host_vtable_t* vtable; } PJ_object_write_host_t; +/* ========================================================================== + * Object-store read host (protocol v4) + * + * Exposed to Toolbox plugins that want to read back ObjectStore entries — + * typically transformer-style plugins that consume bytes and emit results. + * Read access uses an opaque OWNING handle model: each successful + * read_latest_at allocates a refcounted box that keeps the bytes alive + * independent of the store's internal state (matches + * `shared_ptr>` in the C++ API). + * + * Lifetime contract: a handle remains valid until the consumer calls + * release_bytes(handle).

Achieved by adding an optional second service the parser resolves alongside the scalar write host, same pattern already used for pj.colormap.v1. - C ABI: PJ_parser_object_write_host_vtable_t (push_owned + push_lazy; topic bound by the host at service-creation time - same shape as the scalar PJ_parser_write_host_vtable_t but for the object path) + PJ_parser_object_write_host_t. - Service trait: ParserObjectWriteHostService -> "pj.parser_object_write.v1". - SDK view: sdk::ParserObjectWriteHostView with pushOwned / pushLazy(Fetch&&). Same heap-allocated move-capture box pattern as SourceObjectWriteHostView for the lazy closure. - MessageParserPluginBase::bind() resolves the service via services.optional<>(); objectWriteHost() returns nullptr when absent. Media-capable parsers check inside parse() and emit header scalars to writeHost() plus the media payload to objectWriteHost() from one call. - Host plumbing: DatastoreParserObjectWriteHost(ObjectStore&, uint32_t topic_id) - holds the bound ObjectTopicId in state, the parser never names topics. Reuses the PluginFetchCtx shared_ptr pattern from phase 1 so fetch_ctx_destroy runs exactly once per evicted lazy entry. Tests: 4 cases in plugin_parser_object_write_test - parser writes both scalar + object from one parse() call; parser falls back to scalar-only when the object service is absent; SDK pushLazy wires through the parser vtable; unbound view returns error. 69/69 ctest green under Debug+ASAN. Note: PJ_parser_binding_request_t extension (adding optional object_topic field for delegated ingest from DataSources) is deferred to the MCAP port in phase 6 - the host-side plumbing to register the second service per binding lives in pj_plugins and will land with the MCAP changes. --- pj_base/include/pj_base/plugin_data_api.h | 44 ++++ .../sdk/message_parser_plugin_base.hpp | 27 ++- .../include/pj_base/sdk/plugin_data_api.hpp | 80 +++++++ .../include/pj_base/sdk/service_traits.hpp | 13 ++ pj_datastore/CMakeLists.txt | 1 + .../include/pj_datastore/plugin_data_host.hpp | 23 ++ pj_datastore/src/plugin_data_host.cpp | 93 ++++++++ .../tests/plugin_parser_object_write_test.cpp | 214 ++++++++++++++++++ 8 files changed, 494 insertions(+), 1 deletion(-) create mode 100644 pj_datastore/tests/plugin_parser_object_write_test.cpp diff --git a/pj_base/include/pj_base/plugin_data_api.h b/pj_base/include/pj_base/plugin_data_api.h index 66d5513..7a93ce7 100644 --- a/pj_base/include/pj_base/plugin_data_api.h +++ b/pj_base/include/pj_base/plugin_data_api.h @@ -554,6 +554,50 @@ typedef struct { const PJ_object_write_host_vtable_t* vtable; } PJ_object_write_host_t; +/* ========================================================================== + * Parser-scoped object write host (protocol v4) + * + * The MessageParser analogue of PJ_parser_write_host_vtable_t for the object + * path.

Three documented keys from OBJECT_STORE_DESIGN.md §4 become typed methods so typos fail to compile; raw extras + quoted-string extras for format-specific fields. Usage: auto meta = MediaMetadataBuilder() .mediaClass("image") .encoding("jpeg") .schema("sensor_msgs/CompressedImage") .extraString("source", "camera_0") .build(); host.registerTopic(name, meta); Minimal - no external JSON library dependency, proper escaping for quotes/backslashes/control chars. Empty keys omitted, non-empty keys emitted in canonical order (media_class, encoding, schema, extras). Tests: 9 cases covering empty builder, single-key round-trips, canonical ordering, extras (raw + quoted), escape sequences. 70/70 ctest green under Debug+ASAN. Notes on Phase 4 scope: - Typed ObjectTopicHandle already landed in phase 1 via the struct-wrapped uint32_t pattern matching TopicHandle / FieldHandle. - pushOwned(vector&&) rvalue overload is not worth it: the C ABI requires (const uint8_t*, size_t), so the host-side trampoline copies into its own std::vector regardless. --- pj_base/CMakeLists.txt | 1 + .../include/pj_base/sdk/media_metadata.hpp | 151 ++++++++++++++++++ pj_base/tests/media_metadata_test.cpp | 66 ++++++++ 3 files changed, 218 insertions(+) create mode 100644 pj_base/include/pj_base/sdk/media_metadata.hpp create mode 100644 pj_base/tests/media_metadata_test.cpp diff --git a/pj_base/CMakeLists.txt b/pj_base/CMakeLists.txt index e377fab..12876b9 100644 --- a/pj_base/CMakeLists.txt +++ b/pj_base/CMakeLists.txt @@ -55,6 +55,7 @@ if(PJ_BUILD_TESTS) tests/abi_layout_sentinels_test.cpp tests/platform_test.cpp tests/arrow_holders_test.cpp + tests/media_metadata_test.cpp ) foreach(test_src ${PJ_BASE_TESTS}) diff --git a/pj_base/include/pj_base/sdk/media_metadata.hpp b/pj_base/include/pj_base/sdk/media_metadata.hpp new file mode 100644 index 0000000..d2c38d5 --- /dev/null +++ b/pj_base/include/pj_base/sdk/media_metadata.hpp @@ -0,0 +1,151 @@ +#pragma once + +#include +#include + +namespace PJ::sdk { + +/// Builder for the `metadata_json` string attached to an ObjectStore topic +/// at registration time.

All fallible ABI calls now carry a structured `PJ_error_t*` out-param (inline 304-byte struct with domain + message + growth-path `extended`/`extended_kind` slots). The three dedicated write-host vtables become services registered under canonical reverse-DNS names (`pj.source_write.v1`, `pj.parser_write.v1`, `pj.toolbox_host.v1`, `pj.runtime.v1`, `pj.toolbox_runtime.v1`, `pj.colormap.v1`). `get_dialog` returns a typed `PJ_borrowed_dialog_t` fat pointer instead of an untyped `void*`. Every family vtable shares the same 9-slot lifecycle prefix. On top of that, this commit lands the v3.1 hardening that locks down forward compatibility so future additive growth doesn't break existing plugins: E0 — Boot-level ABI symbol + min-vtable-size floor Every plugin .so exports `pj_plugin_abi_version` as a C symbol; loaders dlsym it before touching the vtable. Each family header defines `PJ__MIN_VTABLE_SIZE` (pinned at v3.0, never grows); loaders accept `struct_size >= MIN_SIZE` instead of `>= sizeof(host_struct)`, which would falsely reject plugins compiled against older headers. New tail slots are gated by `PJ_HAS_TAIL_SLOT(vtable_type, ptr, field)`. E1 — PJ_error_t growth path Appended `const void* extended` + `char extended_kind[32]` to PJ_error_t (struct grew from 260 B to 304 B). Future cause chains, stack traces, and structured payloads fit without a v4 break. `sdk::fillError` clears both new fields on every write to prevent stale-pointer reuse. Helpers `setExtended`/`hasExtended` added. E2 — CLAP-style plugin extension query Each family vtable grows a tail slot `const void* get_plugin_extension(ctx, id)`. SDK base classes expose `pluginExtension(std::string_view)` virtual; host handles expose `getPluginExtension(id)` with tail-slot gating. Mock toolbox advertises `pj.experimental.mock_diagnostics/draft-1` for integration testing. E3 — Compile-time ABI layout sentinels New `pj_base/tests/abi_layout_sentinels_test.cpp` pins sizeof/alignof/offsetof for every ABI-visible struct, enum sizes (defends against -fshort-enums), and `sizeof(void*) == 8`. A failing static_assert catches accidental field reorders in PRs. E4 — Compile-time service-name validation `detail::isValidServiceName` is constexpr; every trait's `kName` gets a static_assert. Enforces `"pj..v"` (stable) or `"pj.experimental./draft-"` (unstable) at definition site — no runtime string-parse on every registration. E5 — FROZEN vs APPENDABLE struct labels Header comments at every ABI-visible struct declare the policy. FROZEN = layout permanent (PJ_error_t, fat pointers, handles); APPENDABLE = tail slots may grow (all *_vtable_t types). E6 — Registry runtime hardening `ServiceRegistryBuilder::tryRegisterService` returns Expected; rejects null ctx/vtable and silent-overwrite duplicates. `dispatchGetService` null-checks before returning the fat pointer. Documentation: `pj_plugins/docs/ARCHITECTURE.md` gains a "§0a. ABI stability and evolution rules (v3.1)" section listing all seven rules plus the plugin-extension query contract. Tests that exercised the removed v1/v2 slots (data_source_plugin_base_test, message_parser_plugin_base_test, delegated_ingest_integration_test) are gated off in CMakeLists with TODO(v3-port) markers; coverage is retained by the integration-level *_library_test.cpp suite. * fix(v3): enforce one-shot bind + toolbox service name + error hygiene Three correctness fixes identified by the ABI migration review: 1. Double bind() on DataSource plugins. DataSourceSession::bindRuntimeHostForDialog() was binding a runtime-only registry before the dialog, and setupAndStart() was rebinding the full registry afterward — calling bind() twice per plugin instance. The v3 protocol requires bind() to be one-shot. Fixed by creating the dataset + write host up-front in a new DataSourceSession::bindForDialog() method, so the full registry (source_write + runtime) is ready before the dialog is shown. Renamed setupAndStart() → applyConfigAndStart() to reflect that it no longer binds; added an idempotency guard (bound_ flag) so a second call is a no-op. Side-effect: an empty dataset remains if the user cancels the dialog — acceptable for now, documented inline. Updated call sites in main_window.cpp (onLoadFile, onStartStream, startDummyStream, restartSession). 2. Toolbox service name mismatch. service_traits.hpp defined ToolboxHostService::kName as "pj.toolbox_host.v1" but every doc and comment referenced "pj.toolbox_write.v1" — the name used for consistency with "pj.source_write.v1" and "pj.parser_write.v1". Renamed to match the docs; the C++ trait keeps its historical name because the underlying vtable type is PJ_toolbox_host_t. 3. DialogPluginBase::storeError left v3.1 growth slots uncleared. The local storeError() helper in dialog_plugin_base.hpp set code/domain/message via a writeField lambda but did not reset the new extended / extended_kind slots added in v3.1. A reused PJ_error_t struct could therefore carry a stale extended pointer across calls. Fixed by clearing both slots, matching the sdk::fillError discipline. All 38 non-ASAN-incompatible tests pass. * feat(v4 ABI): Phase 1a — Arrow C Data Interface + noexcept + thread tags Part 1 of the v4 ABI migration (Arrow C Data Interface at the plugin boundary — see .claude/plans/brainstorm-if-what-the-cosmic-wozniak.md). Data-plane changes (pj_base/plugin_data_api.h): * Inlined Arrow C Data Interface POD types (ArrowSchema / ArrowArray / ArrowArrayStream) under the standard ARROW_C_DATA_INTERFACE guard. * SourceWriteHost and ToolboxHost: append_arrow_ipc REMOVED, replaced with append_arrow_stream (producer-owned release, pull-model ingest). * ToolboxHost: read_series + PJ_materialized_series_t REMOVED, replaced with read_series_arrow (host-owned ArrowSchema + ArrowArray). * ParserWriteHost: append_arrow_ipc REMOVED (parsers are per-record; host coalesces internally). ABI hardening: * Every vtable slot is now PJ_NOEXCEPT (C++17 type-level noexcept, no-op in C). Trampolines that drop exceptions through the ABI now terminate the plugin deterministically instead of unwinding. * Every slot carries a thread-class tag: [main-thread], [stream-thread], [thread-safe]. * PJ_ABI_VERSION bumped 3 -> 4. Per-family PROTOCOL_VERSION bumped 3 -> 4. * MIN_VTABLE_SIZE re-pinned at v4.0 (get_plugin_extension is now part of the baseline, no longer a tail slot). SDK updates (pj_base/sdk/*): * All four base classes (DataSourcePluginBase, MessageParserPluginBase, ToolboxPluginBase, DialogPluginBase) + their detail/*_trampolines.hpp thunks updated to noexcept. * PJ_*_PLUGIN macros emit noexcept on PJ_get_*_vtable entry points. * SourceWriteHostView / ToolboxHostView: - appendArrowIpc replaced with appendArrowStream (ownership- transfer on success). - readSeries replaced with readSeriesArrow (caller-owned Arrow structs). * ParserWriteHostView: appendArrowIpc removed. Host-side (pj_datastore/src/plugin_data_host.cpp): * Stubbed implementations of append_arrow_stream and read_series_arrow return a clear "not yet implemented (Phase 1b)" error. The real nanoarrow-backed implementations land in Phase 1b. * All trampolines noexcept. * Dropped MaterializedSeriesState and its 200-line readSeries method. Verification: * abi_layout_sentinels_test updated with v4 offsets/sizes. MIN floors now at v4.0: DataSource=128, MessageParser=80, Toolbox=88. * Release build: 60/60 tests pass. * Debug+ASAN build: 36/41 pass; the 5 failures are the pre-existing RTLD_DEEPBIND + ASAN dlopen incompatibilities (fixed in Phase 1d). * plugin_host_write_test and plugin_host_read_test disabled in CMake pending Phase 1b (they exercise the v3 materialised-vector read path that no longer exists at the ABI). ABI_migration_PLAN.md retires in Phase 3. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(v4 ABI): Phase 1b — host-side Arrow stream implementation Fills in the stubs left by Phase 1a with real, working implementations of append_arrow_stream and read_series_arrow. arrow_import refactor: * Factored per-batch ingest logic out of importIpcStream into a new private ingestBatchesFromStream helper that works on any ArrowArrayStream* — IPC-backed or producer-owned. No functional change for the IPC path; shared code path guarantees the two stay in sync. * Factored schema-parsing logic into a private mappingsFromSchema helper. schemaFromIpc and the new schemaFromArrowStream both use it. * New public entry points: importArrowStream(writer, topic, stream, mappings, ts_col) schemaFromArrowStream(stream) Both preserve caller-side ownership of the stream — the importer never calls stream->release. Host-side wiring (plugin_data_host.cpp): * WriteCore::appendArrowStream replaces the old appendArrowIpc. * ToolboxCore::readSeriesArrow materialises one field's time series into a host-owned struct ArrowArray with two columns: ["timestamp" (int64), (typed)]. Built via nanoarrow. Supports all primitive types including strings. * sourceAppendArrowStream / toolboxAppendArrowStream trampolines now enforce the ABI ownership contract: on success the host calls stream->release before returning; on failure the plugin retains responsibility. Test (new): * arrow_stream_round_trip_test — end-to-end round trip through the v4 ABI. Builds an in-memory ArrowArrayStream, feeds it through append_arrow_stream, reads back via read_series_arrow, compares values exactly. Confirms schema shape and release-callback hygiene. Verification: * Release build: 60/60 tests pass. * Debug+ASAN: 37/42 pass (new round-trip test added and green). The 5 failures are the pre-existing RTLD_DEEPBIND + ASAN dlopen incompatibilities (Phase 1d fixes them). Co-Authored-By: Claude Opus 4.7 (1M context) * feat(v4 ABI): Phase 1c — SDK Arrow holders + manifest sidecar emission Two Phase 1c deliverables, both additive (no ABI change): 1. Arrow C Data Interface RAII holders (pj_base/sdk/arrow.hpp). Move-only wrappers around the three Arrow C Data Interface POD types declared in the ABI header (ArrowSchema, ArrowArray, ArrowArrayStream). Each holder calls release on destruction iff release != nullptr. Makes the common "produce -> hand to host -> release" and "receive from host -> use -> release" patterns exception-safe and terse: ArrowSchemaHolder schema; ArrowArrayHolder array; auto s = toolbox.readSeriesArrow(field, schema.out(), array.out()); // schema/array auto-release at scope exit Zero-dep: stdlib only. Plugins that want richer Arrow builders link nanoarrow themselves. New test arrow_holders_test verifies destructor/move/reset/out/release semantics plus the post-host-takes-ownership inert path. 2. Plugin manifest sidecar emission (cmake/PjPluginManifest.cmake). CMake function pj_emit_plugin_manifest(target FAMILY [MANIFEST_FILE ] [ABI_MAJOR ]) reads the plugin's existing manifest.json (the same file pj_embed_manifest bakes into the DSO), augments it with auto-generated "abi_major" and "family" keys, and writes a sidecar .pjmanifest.json next to the built DSO and at install time. Lets a host scan all installed plugins at startup without dlopen'ing any — essential at the 20-50 plugin target scale. The DSO manifest is still the source of truth; host-side scanning will (Phase 1d) verify sidecar vs DSO on activation and fall back to DSO on mismatch. Root CMakeLists.txt now prepends cmake/ to CMAKE_MODULE_PATH and unconditionally includes the helper, so plugins just call the function without boilerplate include lines. Verification: * Release build: 60/60 tests pass. * Debug+ASAN: 38/43 pass (new arrow_holders_test green; same 5 pre-existing RTLD_DEEPBIND failures to be fixed in Phase 1d). * Verified sidecar emission end-to-end: data_load_csv_plugin writes csv_source_plugin.pjmanifest.json with abi_major=4 and family="data_source" injected on top of the plugin's existing manifest.json content. (The CMake wiring of the CSV plugin lives in the pj_ported_plugins repo; committed there separately.) Co-Authored-By: Claude Opus 4.7 (1M context) * feat(v4 ABI): Phase 1d — drop RTLD_DEEPBIND + sidecar scanner Two Phase 1d deliverables: 1. Loader hardening: drop RTLD_DEEPBIND (pj_plugins/src/detail/library_loader.hpp) The v3 loader set RTLD_NOW | RTLD_LOCAL | RTLD_DEEPBIND on glibc. DEEPBIND is a documented AddressSanitizer trap — ASAN flat-out refuses to dlopen anything with DEEPBIND because it bypasses LD_PRELOAD'd malloc interposition (same issue with jemalloc/ tcmalloc/mimalloc in production). That cost us all five pre-existing debug+ASAN failures. Dropping DEEPBIND fixes them. Plugin-local symbol isolation is instead left to -fvisibility=hidden on plugin builds, to be enforced when each plugin is ported. 2. Sidecar-based plugin discovery (plugin_catalog.hpp + plugin_catalog.cpp). New public API: PJ::scanPluginSidecars(directory) -> Expected> Scans a directory non-recursively for *.pjmanifest.json files, decodes each into a typed PluginDescriptor (name, version, abi_major, family, description, category, encoding, file_extensions, capabilities, sidecar_path, dso_path), and returns them sorted. Malformed sidecars are skipped silently. Uses nlohmann_json. Zero dlopen — the whole point of sidecar discovery. Companion to pj_emit_plugin_manifest (Phase 1c): CMake writes the sidecars at build time; scanPluginSidecars reads them at startup. Test plugin_catalog_test exercises eight cases: missing directory, empty directory, valid sidecar round-trip, malformed JSON skipped, missing required keys skipped, unknown family skipped, non-sidecar files ignored, sorted output, family toString round-trip. Verification: * Release build: 60/60 tests pass. * Debug+ASAN: 44/44 tests pass — the 5 pre-existing data_source_library_test / source_dialog_integration_test / file_source_integration_test / message_parser_library_test / toolbox_plugin_test failures that survived v3.1 are now GREEN. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(v4 ABI): Phase 2 (core side) — sidecar integration test + v3 note drop Phase 2 is "port plugins to v4." On core-side (plotjuggler_core) the work is scaffolding: - plugin_catalog_test gains an optional integration test that, when PJ_BUILD_PORTED_PLUGINS is on, scans the build-tree output directory for the 4 file-source plugin sidecars produced by pj_emit_plugin_manifest and verifies every entry parses cleanly with abi_major==4 and a known family. Closes the loop end-to-end: CMake emits sidecars on build, scanner reads them at test time. - CMake wires the test with a generator-expression sidecar dir and depends on the four plugin targets so the sidecars exist by the time the test runs. Plus one cleanup, flagged as "not an official version": - pj_base/CMakeLists.txt: drop the stale TODO(v3-port) tag. The two retired unit tests (data_source_plugin_base_test, message_parser_plugin_base_test) exercised ABI slots that are long gone; the service-registry-era coverage lives in the *_library_test.cpp integration tests. Either rewrite or delete them — noted but not tackled here. The plugin-side edits (pj_emit_plugin_manifest calls in data_load_mcap, data_load_parquet, data_load_ulog; and the v3-era comment in pj_ported_plugins/CMakeLists.txt) live in the pj_official_plugins repo and are committed separately. Verification: release 60/60, debug+ASAN 44/44. Integration test proves the catalog scanner successfully parses the sidecars emitted by the four v4-ready file-source plugins. Co-Authored-By: Claude Opus 4.7 (1M context) * docs(v4 ABI): Phase 3 — align plugin docs to v4 + retire migration plan Plugin ARCHITECTURE.md gets the v4 landing pass: * Header "ABI stability and evolution rules" re-tagged v4 (was v3.1). * MIN_VTABLE_SIZE floor text now pinned at v4.0 instead of v3.0. * "Protocol v3 (current)" section renamed to "Protocol v4 (current)" and rewritten to list the v4-distinguishing features up front: Arrow C Data Interface at the boundary (append_arrow_stream + read_series_arrow), PJ_NOEXCEPT on every slot, thread-class tags, sidecar-based discovery via pj_emit_plugin_manifest + scanPluginSidecars, RTLD_DEEPBIND removal. * The "inherited from the pre-v4 design" callout acknowledges v3 as the internal-only iteration it was: its structural changes (service registry, error out-params, typed borrowed dialog) carry forward into v4 verbatim but it was never an official release. * Protocol-version table now shows 4 for every family (was a mix of stale 1s and 2s). All four plugin author guides gain a short "> Tracks the v4 plugin ABI" callout at the top pointing readers to ARCHITECTURE.md as the binding reference. The bodies of the guides still have some v1/v2-era lifecycle prose (bind_write_host, bind_runtime_host) that describes the old design; those sections are historical context and need rewriting in a separate author-ergonomics pass. The four reference plugins (data_load_csv, data_load_mcap, data_load_parquet, data_load_ulog) are the working v4 examples. Also retires the scratch ABI_migration_PLAN.md at the repo root — it was superseded by this whole v4 effort. Verification: release 60/60, debug+ASAN 44/44. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(v4 ABI): Phase 0 — abidiff ABI drift gate + v4.0 baseline Closes the v4 migration loop: with every other phase landed, the ABI is now frozen against drift by an opt-in abidiff CI gate. Components: * cmake/PjAbiCheck.cmake — opt-in via -DPJ_ENABLE_ABI_CHECK=ON. Emits two targets: abi_check run abidiff baseline.abi vs current DSO abi_update_baseline regenerate baseline (intentional ABI change) Also registers abi_check_test with CTest so it runs as part of the normal ./test.sh flow when the option is on. * cmake/PjAbiCheckRun.cmake — interprets abidiff exit-bit mask: bit 0/1 (tool/user error) hard fail bit 4 (compatible change) warn + continue bit 8 (INCOMPATIBLE change) hard fail Warnings carry a pointer to the abi_update_baseline target so refreshing is one command. * pj_base/abi/baseline.abi — XML snapshot of the v4.0 ABI surface from libmock_data_source_plugin.so, filtered to types reachable from pj_base/include via --headers-dir. Exempted from the check-added-large-files pre-commit hook (it's an intentional reference artifact, ~1.1 MB). * Top-level CMakeLists.txt adds PJ_ENABLE_ABI_CHECK (default OFF) and includes the helper after all targets are defined. Verified: * abi_check passes on the current tree (exit 0, no drift). * Simulated drift correctly produces a bit-4 warning. * debug+ASAN: 45/45 (new abi_check_test green). Co-Authored-By: Claude Opus 4.7 (1M context) * docs(v4 ABI): align plugin guides to v4 Arrow C Data Interface reality The v4 merge replaced append_arrow_ipc with append_arrow_stream on the source and toolbox write hosts, dropped the Arrow slot from parsers entirely, and added read_series_arrow + the ArrowSchemaHolder / ArrowArrayHolder / ArrowStreamHolder RAII wrappers — but the prose in the plugin guides still showed the old appendArrowIpc/readSeries names. This sweep: - Fixes every remaining appendArrowIpc / readSeries reference in the four SDK tutorials and REQUIREMENTS.md. - Adds a worked readSeriesArrow example to toolbox-guide.md and a worked appendArrowStream example (with ownership-transfer dance) to data-source-guide.md. - Rewrites the parser-guide Arrow section as an explicit 'per-record only; redirect bulk flows to DataSource' note. - Documents the Arrow-at-boundary ownership contract, the manifest sidecar format + pj_emit_plugin_manifest CMake helper, and the abidiff drift gate as new subsections in ARCHITECTURE.md. - Clarifies that MaterializedSeries is a host-internal C++ type on DatastoreToolboxHost, not part of the ABI surface. No source changes; build + tests still green. * feat(v4 ABI): SDK MaterializedSeriesView for toolbox reads Adds a C++ view around the ArrowSchema + ArrowArray pair returned by ToolboxHostView::readSeriesArrow. Owns both holders (move-only), decodes the Arrow format string into PJ::PrimitiveType, exposes timestamps() as Span aliasing the Arrow buffer, and a family of valuesAs{Float64,Float32,Int32,...}() typed pointer accessors that return nullptr on type mismatch. Also adds ToolboxHostView::readSeries(field) as a convenience wrapper that calls the raw readSeriesArrow slot and returns the view. This gives toolbox plugins a near-drop-in replacement for the pre-v4 'series->timestamps() + series->raw().values.as_float64' API — the port ends up as a ~2-line find/replace per readSeries call rather than a full Arrow-walk rewrite. Format-string → PrimitiveType decoding lives in PJ::sdk::detail, covers the primitive set defined in the Arrow C Data Interface spec. * chore(sdk): fix stale 'protocol v3' comments in v4 SDK headers Eight SDK headers still documented themselves as v3 despite the protocol version constant reading 4. No behavioural change — comment-only fixup. New plugin authors tend to trust header comments before constants, so keeping these accurate matters. * feat(sdk): add PJ::borrowDialog helper; drop plumbing from mock_source_with_dialog Plugin authors no longer need to write extern "C" PJ_DIALOG_EXPORT const PJ_dialog_vtable_t* PJ_get_dialog_vtable() noexcept; at the top of their source just to satisfy getDialog(). The PJ_DIALOG_PLUGIN(DialogT) macro now also specialises a new template PJ::dialogVtableFor(), and PJ::borrowDialog(dialog_) wraps the type-safe vtable lookup + fat-pointer construction into one call. Before: extern "C" PJ_DIALOG_EXPORT const PJ_dialog_vtable_t* PJ_get_dialog_vtable() noexcept; ... PJ_borrowed_dialog_t getDialog() override { return PJ_borrowed_dialog_t{&dialog_, PJ_get_dialog_vtable()}; } After: PJ_borrowed_dialog_t getDialog() override { return PJ::borrowDialog(dialog_); } No ABI change: the exported C symbol PJ_get_dialog_vtable() is still emitted for host dlsym lookup. Only the C++ plugin-author surface is cleaner. mock_source_with_dialog updated as the reference example. * feat(sdk): add appendArrowStream(ArrowStreamHolder&&) rvalue overload The ownership-transfer dance for appendArrowStream previously required plugin authors to manually call (void)stream.release() after a successful append, or the destructor would double-release the stream. Easy to forget. Add an rvalue-reference overload on both SourceWriteHostView and ToolboxHostView that takes the ArrowStreamHolder directly and disarms it on success: PJ::sdk::ArrowStreamHolder stream(buildStream()); auto status = writeHost().appendArrowStream(topic, std::move(stream), "timestamp"); // On success: stream is inert — destructor is a no-op. // On failure: plugin retains ownership — destructor releases. The raw-pointer overload is kept for ABI-escape-hatch use (callers that own the stream through some other mechanism). The ArrowStreamHolder doc-comment in arrow.hpp is updated to recommend the rvalue form first. No behavioural change for existing raw-pointer call sites; new authors pick up the safer pattern by default. * feat(sdk-testing): ship ParserWriteRecorder + port message_parser_library_test Every parser test used to define its own ~60 line ParserWriteRecorder struct with three identical C vtable trampolines + a makeWriteHost() factory. Lift that into a new installed header pj_base/include/pj_base/sdk/testing/parser_write_recorder.hpp exposing: PJ::sdk::testing::ParserWriteRecorder recorder; PJ::ServiceRegistryBuilder registry; registry.registerService(recorder.makeHost()); // ... run parser ... EXPECT_EQ(recorder.rows()[0].fields[0].numeric, 3.14); RecordedField exposes typed slots: .numeric (double, populated for all int/float/bool), .bool_value, .string_value, plus .type (PJ::PrimitiveType) and .is_null. bool values populate both .bool_value and .numeric (1.0/0.0) so tests can assert uniformly. Port message_parser_library_test.cpp as the first user. * feat(sdk-testing): ship ToolboxTestStore — fake toolbox host with Arrow read path The quaternion test previously needed ~130 lines of hand-rolled Arrow C Data Interface plumbing — disjoint ArrowSchema / ArrowArray payload blocks, release callbacks, buffer arrays — just to feed fake data into the toolbox via readSeriesArrow. Lift all of that into a new installed header: pj_plugins/include/pj_plugins/testing/toolbox_test_store.hpp exposing a small builder-style API: PJ::testing::ToolboxTestStore store; store.addTopic("quat") .addField("quat", "x", timestamps, xs) .addField("quat", "y", timestamps, ys); registry.registerService(store.makeHost()); registry.registerService(store.makeRuntimeHost()); // ... run toolbox ... EXPECT_EQ(store.writtenRecords().size(), N); EXPECT_EQ(store.notifyDataChangedCalls(), 1); The store captures append_record writes (reusing the parser-write recorder's RecordedRow shape) and counts host-side activity. Internally it emits the two-column Arrow struct layout readSeriesArrow expects — with disjoint schema/array ownership so holder destruction order doesn't matter. Also exposes: - extendField(): append more samples to simulate incremental data - flatRecords(): flattened (ts, name, value) view for tests that prefer a single linear list * docs(v4 SDK): rewrite Quick Starts to use new helpers The SDK guides had been updated with v4 callouts at the top, but their Quick Start sections and later snippets still showed pre-helper boilerplate — raw dialogContext() overrides, manual ArrowStreamHolder release() dances, no references to the new testing helpers. This pass: - Replaces dialogContext()/void*-returning getters with the new PJ_borrowed_dialog_t getDialog() override + PJ::borrowDialog(dialog_) helper across data-source-guide, toolbox-guide, dialog-plugin-guide, REQUIREMENTS.md and ARCHITECTURE.md. - Updates Arrow-bulk-write examples (data-source-guide, toolbox-guide) to use the new rvalue-ref overload — std::move(stream) — instead of the manual (void)stream.release() after success pattern. - Adds Testing sections to toolbox-guide and message-parser-guide pointing plugin authors at ToolboxTestStore / ParserWriteRecorder so unit tests no longer hand-roll Arrow C Data Interface or host-vtable plumbing. All prose examples now compile mentally against the actual current SDK surface. The one remaining 'appendArrowIpc' reference in message-parser-guide is an intentional negation ('no appendArrowIpc slot on parser write host') kept for documentation value. * docs: V4_STORE plan for plugin-ABI ObjectStore surface Approved plan describing how to extend the v4 plugin ABI so plugins can read/write ObjectStore alongside DataEngine. Six phases; phase 5 (toolbox object write) and auxiliary topic indices (keyframe etc.) are deferred. Canary use case: MCAP plugin — scalars via delegated parser, small markers via pushOwned (eager), image/pointcloud bytes via pushLazy. Video topics deferred in full. * feat(v4 ABI): phase 1 — source object write host Adds the plugin-visible surface for DataSource plugins to write into ObjectStore alongside the existing scalar write host. Composed via the v4 service registry as an optional service — no ABI break, no protocol bump, scalar-only plugins unaffected. New surface: - C ABI: PJ_object_topic_handle_t, PJ_lazy_fetch_fn_t, PJ_object_write_host_vtable_t, PJ_object_write_host_t. - Service trait: SourceObjectWriteHostService -> "pj.source_object_write.v1". - SDK view: sdk::SourceObjectWriteHostView with registerTopic / pushOwned / pushLazy / setRetentionBudget. pushLazy(Fetch&&) hides the fetch_ctx / fetch_ctx_destroy ABI dance behind a C++ lambda via a heap-allocated move-capture box. - DataSourcePluginBase::bind() resolves the service optionally; objectWriteHost() returns nullptr on hosts that don't register it. - Host plumbing: DatastoreSourceObjectWriteHost(ObjectStore&, DatasetId) in pj_datastore, with trampolines that wrap the C-ABI fetch callback in a shared_ptr so fetch_ctx_destroy runs exactly once when ObjectStore drops the entry. Tests: 9 new cases in plugin_data_host_object_test covering register/ push_owned/push_lazy/retention/invalid-topic/unbound-view paths plus an explicit destroy-callback exact-once verification via the raw C ABI. 67/67 ctest green under Debug+ASAN. * feat(v4 ABI): phase 2 — toolbox object read host Exposes ObjectStore read access to Toolbox plugins via a separate service (`pj.toolbox_object_read.v1`) rather than extending the scalar toolbox vtable. Keeps each capability on its own service so transformer-style plugins (read bytes, emit results) that don't need scalar read/write can resolve only what they care about. Read path uses an opaque owning-handle model that mirrors `shared_ptr>`: - C ABI: PJ_object_bytes_handle_t (opaque forward-declared pointer), PJ_object_read_host_vtable_t with lookup_topic / list_topics / topic_metadata / read_latest_at / get_bytes / release_bytes / entry_count / time_range. get_bytes / release_bytes take the handle directly (no ctx) — the handle carries its own state. - SDK: PJ::sdk::ObjectBytes move-only RAII wrapper that calls release_bytes in its destructor. Usable across worker threads because the handle keeps bytes alive independent of the store. - Service trait: ToolboxObjectReadHostService. - SDK view: ToolboxObjectReadHostView with lookupTopic / listTopics / topicMetadata / readLatestAt / entryCount / timeRange. listTopics does a two-call resize dance matching the C ABI. - ToolboxPluginBase::bind() resolves the service optionally; objectReadHost() returns nullptr when the host doesn't register it. - Host plumbing: DatastoreToolboxObjectReadHost allocates an ObjectBytesBox (holding the shared_ptr) per successful read_latest_at, freed by release_bytes. Tests: 11 new cases - read-after-write, destructor exact-once, owning-handle-survives-eviction, lookup/list/metadata round-trip, time_range, read-miss, cross-thread handle move, unbound-view fallbacks, moved-from-holder is empty. 68/68 ctest green under Debug+ASAN. * feat(v4 ABI): phase 3 — parser optional object write service Delivers the "two-host parse()" contract from pj_media/docs/REQUIREMENTS.md Prerequisites **without bumping the parser protocol version**. Achieved by adding an optional second service the parser resolves alongside the scalar write host, same pattern already used for pj.colormap.v1. - C ABI: PJ_parser_object_write_host_vtable_t (push_owned + push_lazy; topic bound by the host at service-creation time - same shape as the scalar PJ_parser_write_host_vtable_t but for the object path) + PJ_parser_object_write_host_t. - Service trait: ParserObjectWriteHostService -> "pj.parser_object_write.v1". - SDK view: sdk::ParserObjectWriteHostView with pushOwned / pushLazy(Fetch&&). Same heap-allocated move-capture box pattern as SourceObjectWriteHostView for the lazy closure. - MessageParserPluginBase::bind() resolves the service via services.optional<>(); objectWriteHost() returns nullptr when absent. Media-capable parsers check inside parse() and emit header scalars to writeHost() plus the media payload to objectWriteHost() from one call. - Host plumbing: DatastoreParserObjectWriteHost(ObjectStore&, uint32_t topic_id) - holds the bound ObjectTopicId in state, the parser never names topics. Reuses the PluginFetchCtx shared_ptr pattern from phase 1 so fetch_ctx_destroy runs exactly once per evicted lazy entry. Tests: 4 cases in plugin_parser_object_write_test - parser writes both scalar + object from one parse() call; parser falls back to scalar-only when the object service is absent; SDK pushLazy wires through the parser vtable; unbound view returns error. 69/69 ctest green under Debug+ASAN. Note: PJ_parser_binding_request_t extension (adding optional object_topic field for delegated ingest from DataSources) is deferred to the MCAP port in phase 6 - the host-side plumbing to register the second service per binding lives in pj_plugins and will land with the MCAP changes. * feat(v4 ABI): phase 4 — MediaMetadataBuilder SDK helper Tiny JSON builder for the metadata_json string attached to ObjectStore topics at registration time. Three documented keys from OBJECT_STORE_DESIGN.md §4 become typed methods so typos fail to compile; raw extras + quoted-string extras for format-specific fields. Usage: auto meta = MediaMetadataBuilder() .mediaClass("image") .encoding("jpeg") .schema("sensor_msgs/CompressedImage") .extraString("source", "camera_0") .build(); host.registerTopic(name, meta); Minimal - no external JSON library dependency, proper escaping for quotes/backslashes/control chars. Empty keys omitted, non-empty keys emitted in canonical order (media_class, encoding, schema, extras). Tests: 9 cases covering empty builder, single-key round-trips, canonical ordering, extras (raw + quoted), escape sequences. 70/70 ctest green under Debug+ASAN. Notes on Phase 4 scope: - Typed ObjectTopicHandle already landed in phase 1 via the struct-wrapped uint32_t pattern matching TopicHandle / FieldHandle. - pushOwned(vector&&) rvalue overload is not worth it: the C ABI requires (const uint8_t*, size_t), so the host-side trampoline copies into its own std::vector regardless. * fix(cmake): derive PJ_HAS_PORTED_PLUGINS and gate plugin_catalog_test on it The top-level already guards add_subdirectory(pj_ported_plugins) with `PJ_BUILD_PORTED_PLUGINS AND EXISTS pj_ported_plugins/CMakeLists.txt`, but pj_plugins/CMakeLists.txt was gating the plugin_catalog_test integration wiring on `PJ_BUILD_PORTED_PLUGINS` alone. In a checkout without the pj_ported_plugins/ tree (the standalone core build), the option stays ON by default and the test ends up referencing targets (csv_source_plugin etc.) that were never added, producing: Error evaluating generator expression: No target "csv_source_plugin" add_dependencies: The dependency target "csv_source_plugin" does not exist. Expose a derived PJ_HAS_PORTED_PLUGINS flag from the top-level — set inside the same existing guard that decides to add the subdirectory — and gate the integration test wiring on it. Convention: PJ_BUILD_* are user inputs; PJ_HAS_* are derived state. plugin_catalog_test itself already falls back to GTEST_SKIP() when PJ_PORTED_PLUGINS_BIN_DIR is not defined, so when the wiring is skipped the test compiles clean and just reports SKIPPED at runtime. * test(pj_base): use custom raw-string delimiter to unblock MSVC build MSVC's preprocessor was tokenizing part of the raw-string body as a user-defined-literal suffix when a backslash sat immediately before the closing quote-paren, producing: error C2017: illegal escape sequence error C3688: invalid literal suffix 'name'; literal operator 'operator ""name' not found GCC and Clang accept the form as the standard prescribes, but switching to a custom delimiter (R"@( ... )@") sidesteps the MSVC quirk without changing the literal's content — the two asserted JSON strings still carry the same bytes. Contents: - pj_base/tests/media_metadata_test.cpp: change R"(...)" to R"@(...)@" in the two literals of EscapesQuotesAndBackslashes + add a short comment explaining the MSVC workaround * test(pj_base): switch raw-string delimiter to 'x' so GCC also accepts it The previous attempt used '@' as the raw-string delimiter to sidestep an MSVC tokenizer quirk, but '@' is not part of the C++ basic source character set and GCC rejects it with: error: invalid character '@' in raw string delimiter Use a plain ASCII letter instead. R"x( ... )x" is accepted as a valid d-char sequence by every conforming compiler and still avoids the MSVC issue with a trailing backslash before the default closing )". The asserted literal content is byte-identical to what the original R"( ... )" produced — only the delimiter marker changes. Contents: - pj_base/tests/media_metadata_test.cpp: change R"@(...)@" to R"x(...)x" in the two literals of EscapesQuotesAndBackslashes and update the workaround comment * test(pj_base): replace failing raw strings with escaped literals for MSVC Two earlier attempts at keeping the raw-string form in this test did not settle the CI build: 1. R"@(...)@" — '@' is not in the basic source character set, so GCC rejected it ("invalid character '@' in raw string delimiter"). 2. R"x(...)x" — GCC accepted it, but MSVC on the CI runner kept failing with "illegal escape sequence" + "invalid literal suffix 'name'", i.e. the preprocessor is falling out of raw-string mode on bodies that combine '"' and '\' and reinterpreting the tail as a user-defined literal suffix. (A global flip to /Zc:preprocessor would work but changes shared compiler settings.) Switch the two literals to ordinary escaped strings. The escapes produce identical byte content, the test asserts the exact same two strings, and every compiler accepts the form regardless of flags. Contents: - pj_base/tests/media_metadata_test.cpp: replace R"x(...)x" with escaped "..." in both the schema() argument and the EXPECT_EQ expected value of EscapesQuotesAndBackslashes; update the

A media-capable parser +overrides `bind()` to resolve both services (`require()` + +`require()` — or `optional()` for +dual-purpose parsers). A scalar-only parser resolves only the scalar +service and keeps working unchanged. **No ABI break**, **no protocol +bump**, **no signature change**. + +This applies the same asymmetry we already use for `pj.colormap.v1` (an +optional service resolved opportunistically by toolboxes that want it). + +--- + +## Phases + +Sequenced so each phase compiles and tests independently.

Media-capable parsers override +`bind()` to tighten the object host from optional to required, or just +check `objectWriteHost() != nullptr` inside `parse()`. + +**Delegated ingest wiring** (host side, +`pj_plugins/src/message_parser_host.cpp`): when the DataSource calls +`ensureParserBinding({topic, encoding, schema, object_topic?})` with an +`object_topic` field, the host's per-binding service registry gets both +services. The `PJ_parser_binding_request_t` struct grows one optional +field: `PJ_object_topic_handle_t object_topic; // 0 == scalar-only`. + +**Tests:** +- `pj_plugins/tests/parser_two_host_test.cpp` — a mock parser receives + both hosts, writes a scalar field and an object payload from a single + `parse()` call, asserts both land. + +### Phase 4 — SDK ergonomics: typed handle, metadata builder + +- **Typed `ObjectTopicHandle`** — not just `uint32_t`. A one-member + struct with `operator==`, `bool(handle)`. Same pattern as the + existing `TopicHandle` / `FieldHandle`. +- **`pushLazy(Fetch&&)` helper** (phase 1) and + **`pushOwned(std::vector&&)` rvalue overload** — move into + the store on the C++ side when we can, fall back to copy on the C + ABI slot. Mirrors the `appendArrowStream(ArrowStreamHolder&&)` + pattern from Tier 1b of the previous plan. +- **`MediaMetadataBuilder`** — tiny helper for constructing the JSON + string the design doc mandates: + ```cpp + auto meta = MediaMetadataBuilder() + .mediaClass("video") + .encoding("h264") + .schema("foxglove/CompressedVideo") + .build(); + host.registerTopic(name, meta); + ``` + Three documented keys (`media_class`, `encoding`, `schema`) become + typed methods; the builder emits minimal valid JSON with no external + dep. Prevents typos that would break viewer auto-routing. + +### Phase 5 — Toolbox object write (transformer plugins, future) + +Deferred. Once transformer plugins become real, add +`pj.toolbox_object_write.v1` reusing the same +`PJ_object_write_host_vtable_t`. All plumbing patterns from phase 1 +apply. + +Not scoped in this plan; noted so reviewers know the shape. + +### Phase 6 — MCAP plugin demonstration + +Once phases 1–4 land, port the MCAP plugin (on `pj_official_plugins`) +to the new surface. Four internal modes: + +1. **Scalar topics** — existing delegated parser binding, unchanged. +2. **Small-message topics (eager)** — e.g. + `visualization_msgs/Marker`, ImageAnnotation, scene primitives. + - At file open: register one object topic per channel with + `MediaMetadataBuilder`. + - Per message: `pushOwned(handle, ts_ns, bytes)` — the store + takes ownership of the serialized payload. No fetch closure, no + shared-reader bookkeeping. +3. **Large-blob topics (lazy)** — still images, point clouds. + - At file open: register one object topic per channel. + - Per message: `pushLazy` with a closure capturing + `{shared_ptr, message.data_offset, + message.data_size}`. +4. **Shared topics** (e.g., `sensor_msgs/CompressedImage` with scalar + `header.seq` + bytes): delegated ingest with a CDR parser that + resolves both `pj.parser_write.v1` and `pj.parser_object_write.v1`, + writes `header.seq` to the former and JPEG bytes to the latter — from + a single `parse()` call. The parser's object-side push is `pushOwned` + here because the parser is given already-deserialized inner bytes + from the CDR envelope — the seek-and-reread shape doesn't apply. + +**Video channels are skipped** at file-open time: the plugin logs them +as "deferred" and does not register object topics for them. See +"Deferred — video topics" in Out of scope. + +Validate end-to-end: open an MCAP with scalars + eager markers + lazy +images, confirm scalars land in `DataEngine`, confirm the markers +channel reports the right `entryCount` immediately after load (no +lazy unroll needed), confirm `latestAt(image_topic, ts)` on the +image channel invokes the fetch callback and returns bytes, confirm +memory after load is dominated by the eager small-message data and +not by the image bytes (lazy closures only), confirm `evictBefore` +tears down `fetch_ctx_destroy` correctly on the lazy channel. + +--- + +## Critical files + +### New files + +| File | Phase | Purpose | +|---|---|---| +| `pj_base/include/pj_base/sdk/object_bytes.hpp` | 2 | `ObjectBytes` RAII wrapper | +| `pj_base/include/pj_base/sdk/object_topic_handle.hpp` | 4 | Typed handle struct | +| `pj_base/include/pj_base/sdk/media_metadata.hpp` | 4 | `MediaMetadataBuilder` | +| `pj_plugins/examples/mock_object_source.cpp` | 1 | Canary plugin | +| `pj_datastore/tests/plugin_data_host_object_test.cpp` | 1 | Write surface tests | +| `pj_datastore/tests/plugin_data_host_object_read_test.cpp` | 2 | Read surface tests | +| `pj_plugins/tests/parser_two_host_test.cpp` | 3 | Two-host parser test | + +### Files touched + +| File | Phase | Change | +|---|---|---| +| `pj_base/include/pj_base/plugin_data_api.h` | 1, 2 | Add two new vtables + handle types | +| `pj_base/include/pj_base/sdk/service_traits.hpp` | 1, 2, 3 | Add three service trait structs | +| `pj_base/include/pj_base/sdk/plugin_data_api.hpp` | 1, 2, 3, 4 | Add three views + RAII helpers | +| `pj_base/include/pj_base/sdk/data_source_plugin_base.hpp` | 1 | `bind()` resolves optional object write | +| `pj_base/include/pj_base/sdk/toolbox_plugin_base.hpp` | 2 | `bind()` resolves optional object read | +| `pj_base/include/pj_base/sdk/message_parser_plugin_base.hpp` | 3 | `bind()` resolves optional object write | +| `pj_datastore/src/plugin_data_host.cpp` | 1, 2 | Add three host classes + trampolines | +| `pj_datastore/src/plugin_data_host.hpp` | 1, 2 | Declare new host classes | +| `pj_base/include/pj_base/data_source_protocol.h` | 3 | `PJ_parser_binding_request_t` gains `object_topic` field | +| `pj_plugins/src/message_parser_host.cpp` | 3 | Delegated-ingest wiring resolves both services | +| `pj_plugins/docs/data-source-guide.md` | 1, 4 | Document new write surface + MCAP pattern | +| `pj_plugins/docs/toolbox-guide.md` | 2 | Document new read surface | +| `pj_plugins/docs/message-parser-guide.md` | 3 | Document optional second host | +| `pj_plugins/docs/ARCHITECTURE.md` | 1–3 | New services in service table | +| `pj_plugins/docs/REQUIREMENTS.md` | 1–3 | Object read/write in permissions table | + +### Reused from existing SDK + +- `PJ::sdk::Status`, `Expected` — `pj_base/expected.hpp` +- `PJ::Timestamp`, `PJ::DatasetId` — `pj_base/types.hpp` +- `ServiceRegistry::optional()` / `require()` — already used for + `pj.colormap.v1` (model to copy) +- Service-trait layout — `service_traits.hpp` (13 existing examples) +- Vtable-builder pattern — `plugin_data_host.cpp` (three existing hosts) +- C-ABI trampoline pattern (exception-safe, `PJ_error_t*` propagation) — + every existing trampoline in `plugin_data_host.cpp` + +### Key existing functions to mirror + +- `DatastoreParserWriteHost` (`plugin_data_host.cpp:912`) — exact + template for topic-scoped object write host. +- `toolboxReadSeriesArrow` — pattern for host-owned resources returned + to plugin via opaque handle + release callback (the same shape used + for `PJ_object_bytes_handle_t`). +- `SourceWriteHostView::appendArrowStream(ArrowStreamHolder&&)` — + template for the `pushLazy(Fetch&&)` ergonomic overload (same + "hide the ABI dance" idea). +- `ServiceRegistry::optional()` — template + for all three new optional services. + +--- + +## Verification + +Each phase is a committable unit.

The MCAP port skips video channels + at open time and logs them as deferred. +- **Auxiliary topic indices** — `publish_keyframe_index` was + deliberately removed from the object write vtable. Keyframe tracking + is one instance of a more general problem: some consumers need + auxiliary, per-topic lookup tables alongside the raw payloads + (keyframe timestamps for video, spatial tiles for large point + clouds, thumbnail timestamps for image-heavy datasets, chapter + markers, etc.). A general mechanism — likely a named-side-channel + API on the ObjectStore, e.g. `attachSideChannel(topic, kind_id, + bytes)` / `getSideChannel(topic, kind_id)` — should be designed + as a separate piece of work and landed after the base ObjectStore + plugin surface is proven. Video topics are the most visible + beneficiary, but they are not the only one. +- **Transformer plugins** (toolbox-side object write) — phase 5 + placeholder only. +- **Disk-backed object persistence** — deferred in + OBJECT_STORE_DESIGN.md §10, still deferred here. +- **Compression of owned bytes** — same. +- **GOP-aware eviction for video** — OBJECT_STORE_DESIGN.md §10; + current eviction is time/memory-only. +- **pj_media_core viewer decoder side** — lives in its own module, + not a plugin concern. The plugin surface here is agnostic to what + viewers do with the bytes. +- **`TimelineCursor`** (pj_base) — separate prerequisite tracked in + `pj_media/docs/REQUIREMENTS.md` Prerequisites; unrelated to the + plugin ABI. +- **Parser protocol version bump** — intentionally avoided by the + optional-service design (see "Design decision"). + +--- + +## Resolved design questions + +1. **Service naming.** Long, caller-scoped — + `pj.source_object_write.v1`, `pj.parser_object_write.v1`, + `pj.toolbox_object_read.v1`. Matches existing v4 naming discipline. +2. **Keyframe index + video topics.** Both deferred entirely. + `publish_keyframe_index` is out of the vtable, and video topics are + skipped by the MCAP port. Keyframe indexing is a special case of a + more general auxiliary-index mechanism that deserves its own + design; delivering only storage for video without decode/seek would + be a half-wired feature. See the two "Deferred — …" bullets in Out + of scope. +3. **Phase 6 scope.** Port the MCAP plugin directly. No synthetic + canary.

Both return view classes that null-check and + * map to `Expected` / `Status`. + * + * The SDK generates C ABI trampolines with full exception safety — any + * exception thrown from a virtual is caught, stored on a per-instance + * error slot, and converted to `false` + populated `PJ_error_t*` across + * the ABI boundary. + * + * See `pj_plugins/examples/mock_data_source.cpp` for a complete example. */ #pragma once @@ -14,303 +29,19 @@ #include #include #include +#include #include "pj_base/data_source_protocol.h" #include "pj_base/expected.hpp" +#include "pj_base/sdk/data_source_host_views.hpp" #include "pj_base/sdk/plugin_data_api.hpp" +#include "pj_base/sdk/service_registry.hpp" +#include "pj_base/sdk/service_traits.hpp" namespace PJ { -/// C++ mirror of PJ_data_source_state_t. -enum class DataSourceState : uint32_t { - kIdle = PJ_DATA_SOURCE_STATE_IDLE, - kConfiguring = PJ_DATA_SOURCE_STATE_CONFIGURING, - kStarting = PJ_DATA_SOURCE_STATE_STARTING, - kRunning = PJ_DATA_SOURCE_STATE_RUNNING, - kPaused = PJ_DATA_SOURCE_STATE_PAUSED, - kStopping = PJ_DATA_SOURCE_STATE_STOPPING, - kStopped = PJ_DATA_SOURCE_STATE_STOPPED, - kFailed = PJ_DATA_SOURCE_STATE_FAILED, -}; - -/// Severity level for plugin-to-host diagnostic messages. -enum class DataSourceMessageLevel : uint32_t { - kInfo = PJ_DATA_SOURCE_MESSAGE_INFO, - kWarning = PJ_DATA_SOURCE_MESSAGE_WARNING, - kError = PJ_DATA_SOURCE_MESSAGE_ERROR, -}; - -/// Type of message box to display (determines icon). -enum class MessageBoxType : uint32_t { - kInfo = PJ_MESSAGE_BOX_INFO, - kWarning = PJ_MESSAGE_BOX_WARNING, - kError = PJ_MESSAGE_BOX_ERROR, - kQuestion = PJ_MESSAGE_BOX_QUESTION, -}; - -/// Standard buttons for message boxes (combinable with |). -enum class MessageBoxButton : int { - kOk = PJ_MSG_BTN_OK, - kCancel = PJ_MSG_BTN_CANCEL, - kYes = PJ_MSG_BTN_YES, - kNo = PJ_MSG_BTN_NO, - kContinue = PJ_MSG_BTN_CONTINUE, - kAbort = PJ_MSG_BTN_ABORT, - kRetry = PJ_MSG_BTN_RETRY, - kIgnore = PJ_MSG_BTN_IGNORE, -}; - -/// Allow combining MessageBoxButton values with |. -inline int operator|(MessageBoxButton a, MessageBoxButton b) { - return static_cast(a) | static_cast(b); -} -inline int operator|(int a, MessageBoxButton b) { - return a | static_cast(b); -} - -/// @name Capability flag constants -/// @{ -constexpr uint64_t kCapabilityFiniteImport = PJ_DATA_SOURCE_CAPABILITY_FINITE_IMPORT; -constexpr uint64_t kCapabilityContinuousStream = PJ_DATA_SOURCE_CAPABILITY_CONTINUOUS_STREAM; -constexpr uint64_t kCapabilityDirectIngest = PJ_DATA_SOURCE_CAPABILITY_DIRECT_INGEST; -constexpr uint64_t kCapabilityDelegatedIngest = PJ_DATA_SOURCE_CAPABILITY_DELEGATED_INGEST; -constexpr uint64_t kCapabilitySupportsPause = PJ_DATA_SOURCE_CAPABILITY_SUPPORTS_PAUSE; -constexpr uint64_t kCapabilityHasDialog = PJ_DATA_SOURCE_CAPABILITY_HAS_DIALOG; -/// @} - -using ParserBindingHandle = PJ_parser_binding_handle_t; - -/// C++ mirror of PJ_parser_binding_request_t for delegated-ingest parser lookup. -struct ParserBindingRequest { - std::string_view topic_name; - std::string_view parser_encoding; - std::string_view type_name; - Span schema; - std::string_view parser_config_json; -}; - /** - * Type-safe C++ view over the runtime host vtable. - * - * Plugins access this via DataSourcePluginBase::runtimeHost().

ABI stability and evolution rules (v4) + +Seven rules the loader and every plugin author rely on.

The host `dlsym`s it BEFORE fetching the family vtable; + missing or mismatched symbol is a fail-fast rejection with a specific + error.

The loader accepts + `struct_size >= MIN_VTABLE_SIZE`. This constant MUST NEVER GROW + within the v4 series. Growing it would reject plugins compiled + against older v4 headers (which correctly report a smaller size), + silently breaking the forward-compatibility promise. + +3. **Tail-slot gating.** Every vtable slot added after v4.0 is a tail + slot. Host reads must go through the `PJ_HAS_TAIL_SLOT(vtable_type, + vtable_ptr, field)` macro, which verifies both that the plugin's + `struct_size` reaches the slot AND that the slot is non-null. Skipping + this gate is undefined behaviour on plugins built against older + headers. + +4. **Frozen vs appendable struct classification.** Each ABI-visible + struct carries a header comment declaring its policy: + - **ABI-FROZEN**: `PJ_error_t`, `PJ_string_view_t`, `PJ_bytes_view_t`, + `PJ_borrowed_dialog_t`, `PJ_service_t`, `PJ_service_registry_t`, + handle types, primitive-value unions. Layout permanent; any change + is a v4 break. `PJ_error_t` has `extended` + `extended_kind` slots + reserved as its one growth path — do not add further top-level + fields. + - **ABI-APPENDABLE**: all `*_vtable_t` types, service-host vtables, + `PJ_service_registry_vtable_t`. New slots at the tail; read with + `PJ_HAS_TAIL_SLOT`. + +5. **Compile-time ABI layout sentinels.** `pj_base/tests/abi_layout_sentinels_test.cpp` + consists entirely of `static_assert`s pinning `sizeof`, `alignof`, + and `offsetof` for every ABI struct plus `sizeof(void*)` (64-bit + guard) and enum-size pins (defends against `-fshort-enums`). A + failed assertion at compile time is ALWAYS a serious signal: + - Offset changes = field reorder = ABI break. + - MIN-size increase = floor moved = forward-compat break. + - sizeof growth = deliberate append, update the assertion. + +6. **Service-name grammar (compile-time enforced).** + | Pattern | Stability | + |---|---| + | `"pj..v"` | Stable. Frozen for ≥3 releases before deprecation. | + | `"pj.experimental./draft-"` | Unstable. No guarantees. | + `sdk/service_traits.hpp` calls `detail::isValidServiceName()` in a + `static_assert` at every trait's `kName`. Requesting a + `pj.experimental.*` service should log a runtime warning through the + `pj.runtime.v1` log channel. + +7. **Exception discipline at the ABI boundary.** Every C ABI entry + point (SDK trampolines and host-side service trampolines) must + catch all exceptions and convert to a `PJ_error_t` out-param (or a + safe default for non-fallible calls). C++ exceptions across + `dlopen` boundaries are undefined behaviour in practice.

Trampolines catch and translate internally. +- **Thread-class tags on every slot.** Every function-pointer field in + the ABI headers carries a `[main-thread]` / `[stream-thread]` / + `[thread-safe]` comment. Host-side runtime checking is optional + (reserved for a future `"pj.thread_check.v1"` service). +- **Sidecar-based plugin discovery.** `pj_emit_plugin_manifest` (CMake + helper in `cmake/PjPluginManifest.cmake`) writes a + `.pjmanifest.json` beside each DSO at build and install + time. The sidecar is the DSO's own `manifest.json` plus two + autogenerated keys — `"abi_major"` (matches `PJ_ABI_VERSION`) and + `"family"` (one of `data_source`, `message_parser`, `toolbox`, + `dialog`). Host-side `PJ::scanPluginSidecars(dir)` (in + `pj_plugins/host/plugin_catalog.hpp`) parses every sidecar in a + directory into `PluginDescriptor` records — name, version, category, + file extensions, encoding, capabilities — WITHOUT dlopen'ing any + shared library. On activation the host dlopens the DSO, calls + `get_plugin_manifest`, and warns (not errors) if the two disagree — + DSO truth wins. +- **No more RTLD_DEEPBIND.** The loader uses `RTLD_NOW | RTLD_LOCAL` + only (DEEPBIND was a documented ASAN/allocator-interposition trap). + Plugin-local symbol isolation is left to `-fvisibility=hidden`. + +Structural shape inherited from the pre-v4 design work (carries the +service registry, error out-params, and typed borrowed-dialog patterns +that had been developed in the unreleased v3 iteration): + +- **Service registry as the sole binding mechanism.** Plugin vtables expose + a single `bind(ctx, registry, err)` slot.

Skipped when PJ_ASAN_ACTIVE (set by -DPJE_ENABLE_SANITIZERS=ON) to preserve ASAN's malloc interposer — the known incompatibility between RTLD_DEEPBIND and LD_PRELOAD'd sanitizer runtimes (google/sanitizers#611). PJ_ASAN_ACTIVE is defined in CMakeLists.txt when PJ_ENABLE_SANITIZERS is on, so ASAN builds continue to pass without DEEPBIND. This restores the behaviour that was working before Phase 1d (commit 1a732ba). It is kept as plan B alongside PR #73 (fix/plugin-visibility- hidden), which pursues the -fvisibility=hidden + -Bsymbolic-functions approach as the longer-term alternative. --- pj_plugins/src/detail/library_loader.hpp | 21 ++++++++++----------- 1 file changed, 10 insertions(+), 11 deletions(-) diff --git a/pj_plugins/src/detail/library_loader.hpp b/pj_plugins/src/detail/library_loader.hpp index cfdb9b6..6f59412 100644 --- a/pj_plugins/src/detail/library_loader.hpp +++ b/pj_plugins/src/detail/library_loader.hpp @@ -33,18 +33,17 @@ inline Expected loadLibraryHandle(std::string_view path) { // RTLD_LOCAL — keep plugin symbols out of the global symbol pool; each // plugin resolves its own copies of bundled statics in // isolation from other plugins and from the host. - // - // Historical note: we USED to also set RTLD_DEEPBIND on glibc to force - // the plugin's own symbol scope ahead of the global one (Conan OpenSSL - // vs system libcrypto, etc.).
