When a reload is requested (via +:program:`traffic_ctl` or the JSONRPC API — see :ref:`admin_config_reload` and +:ref:`get_reload_config_status`), it coordinates execution, tracks progress per handler, +and records the result in a queryable history. + +Key capabilities: + +- **Traceability** — every reload gets a token. Each handler reports its status and the results + are aggregated into a task tree with per-handler timings and logs. +- **Centralized registration** — one place for config files, filename records, trigger records, and + handlers. +- **Inline YAML injection** — handlers that opt in can receive YAML content directly via the RPC, + without writing to disk. +- **Coordinated reload sessions** — concurrency control, timeout detection, and history. + + +Registration API +================ + +All registration calls are made during module startup, typically from a ``startup()`` method. + +register_config +--------------- + +Register a file-based configuration handler. + +.. code-block:: cpp + + void ConfigRegistry::register_config( + const std::string &key, // unique registry key (e.g. "ip_allow") + const std::string &default_filename, // default filename (e.g. "ip_allow.yaml") + const std::string &filename_record, // record holding the filename, or "" if fixed + ConfigReloadHandler handler, // reload callback + ConfigSource source, // content source (FileOnly, FileAndRpc) + std::initializer_list triggers // records that trigger reload (optional) + ); + +This is the primary registration method.

It provides methods to +report progress and access inline YAML content. + +``ConfigContext`` is copyable (cheap — holds a ``weak_ptr`` and a ref-counted ``YAML::Node``). +Move is intentionally suppressed: ``std::move(ctx)`` silently copies, keeping the original valid. + +in_progress(text) + Mark the task as in-progress.

This means + calling ``complete()`` or ``fail()`` from any thread — including a different ``ET_TASK`` + thread or a callback — is safe. + +After ``ConfigRegistry::execute_reload()`` calls the handler, it checks whether the context reached +a terminal state and emits a warning if not: + +.. code-block:: cpp + + entry_copy.handler(ctx); + if (!ctx.is_terminal()) { + Warning("Config '%s' handler returned without reaching a terminal state. " + "If the handler deferred work to another thread, ensure ctx.complete() or " + "ctx.fail() is called when processing finishes.", + entry_copy.key.c_str()); + } + + +Parent Status Aggregation +------------------------- + +Parent tasks derive their status from their children: + +- **Any child failed or timed out** → parent is ``FAIL`` +- **Any child still in progress** → parent stays ``IN_PROGRESS`` +- **All children succeeded** → parent is ``SUCCESS`` + +This aggregation is recursive. A parent's ``complete()`` call sets its own status, but if any child +later fails, the parent status will be downgraded accordingly. + + +ConfigSource +============ + +``ConfigSource`` declares what content sources a handler supports: + +``FileOnly`` + The handler only reloads from its file on disk. This is the default for most configs. + Inline YAML via the RPC (:ref:`admin_config_reload`) is rejected. + +``RecordOnly`` + The handler only reacts to record changes. It has no config file and no RPC content. + Used by ``register_record_config()`` implicitly. + +``FileAndRpc`` + The handler can reload from file **or** from YAML content supplied via the RPC. The handler + checks ``ctx.supplied_yaml()`` to determine the source at runtime. + + +ConfigType +========== + +``ConfigType`` identifies the file format. It is **auto-detected** from the filename extension +during registration: + +- ``.yaml``, ``.yml`` → ``ConfigType::YAML`` +- All others → ``ConfigType::LEGACY`` + +You do not set this manually — ``register_config()`` infers it from the ``default_filename``. + + +Adding a New Config Module +========================== + +Step-by-step guide for adding a new configuration file to the reload framework. + +Step 1: Choose a Registry Key +------------------------------ + +Pick a short, lowercase, underscore-separated name that identifies the config. This key is used +in ``traffic_ctl config status`` output, JSONRPC APIs, and inline YAML reload files. + +Examples: ``ip_allow``, ``logging``, ``cache_control``, ``ssl_ticket_key``, ``ssl_client_coordinator`` + +For record-only configs (registered via ``register_record_config()``), the key identifies a group +of records that share a handler — e.g. ``ssl_client_coordinator``. + +.. note:: + + Not all records support runtime reload. Records declared with ``RECU_DYNAMIC`` in + ``RecordsConfig.cc`` can trigger a handler at runtime. Records marked ``RECU_RESTART_TS`` + require a server restart and are **not** affected by the reload framework. Only register + records that are ``RECU_DYNAMIC`` as trigger records for your handler. + +Step 2: Accept a ``ConfigContext`` Parameter +-------------------------------------------- + +Your handler function must accept a ``ConfigContext`` parameter. Use a default value so the +handler can also be called at startup without a reload context: + +.. code-block:: cpp + + // In the header — any function name is fine, "reconfigure" is the common convention: + static void reconfigure(ConfigContext ctx = {}); + +A default-constructed ``ConfigContext{}`` is a **no-op context**: all status calls +(``in_progress()``, ``complete()``, ``fail()``, ``log()``) are safe no-ops. This means the +same handler works at startup (no active reload) and during a reload (with tracking). + +Step 3: Report Progress +----------------------- + +Inside the handler, report progress through the context: + +.. code-block:: cpp + + void MyConfig::reconfigure(ConfigContext ctx) { + ctx.in_progress(); + + // ... load and parse config ... + + if (error) { + ctx.fail(errata, "Failed to load myconfig.yaml"); + return; + } + + ctx.log("Loaded {} rules", rule_count); + ctx.complete("Finished loading"); + } + +.. warning:: + + Remember the :ref:`terminal state rule `: + every code path must end with ``complete()`` or ``fail()``. + +Step 4: Register with ``ConfigRegistry`` +----------------------------------------- + +Call ``register_config()`` (or ``register_record_config()``) during your module's initialization +— typically in a function you call at server startup. The function name is up to you; the +convention in existing code is ``startup()``, but any name works. + +.. code-block:: cpp + + void MyConfig::startup() { // or init(), or any name + config::ConfigRegistry::Get_Instance().register_config( + "myconfig", // registry key + "myconfig.yaml", // default filename + "proxy.config.mymodule.filename", // record holding filename + [](ConfigContext ctx) { MyConfig::reconfigure(ctx); }, // handler + config::ConfigSource::FileOnly, // content source + {"proxy.config.mymodule.filename"}); // triggers + + // Initial load — ConfigContext{} is a no-op, so all ctx calls are safe + reconfigure(); + } + +Step 5: Add File Dependencies (if needed) +------------------------------------------ + +If your config depends on auxiliary files, register them: + +.. code-block:: cpp + + config::ConfigRegistry::Get_Instance().add_file_dependency( + "myconfig", + "proxy.config.mymodule.aux_filename", + "myconfig_aux.yaml", + false); // not required + +Step 6: Support Inline YAML (optional) +--------------------------------------- + +To accept YAML content via the RPC (``traffic_ctl config reload -d`` / +:ref:`admin_config_reload` with ``configs``): + +1. Change the source to ``ConfigSource::FileAndRpc`` in the registration call. +2. Check ``ctx.supplied_yaml()`` in the handler: + +.. code-block:: cpp + + void MyConfig::reconfigure(ConfigContext ctx) { + ctx.in_progress(); + + YAML::Node root; + if (auto yaml = ctx.supplied_yaml()) { + // Inline mode: content from RPC. Not persisted to disk. + root = yaml; + } else { + // File mode: read from disk. + root = YAML::LoadFile(config_filename); + } + + // ... parse and apply ... + + ctx.complete("Loaded successfully"); + } + + +Composite Configs +================= + +Some config modules coordinate multiple sub-configs. For example, ``SSLClientCoordinator`` owns +``sni.yaml`` and ``ssl_multicert.config`` as children. + +Pattern: + +1. Register with ``register_record_config()`` (no primary file). +2. Add file dependencies with ``add_file_and_node_dependency()`` for each child. +3. In the handler, create child contexts with ``add_dependent_ctx()``. + +.. code-block:: cpp + + void SSLClientCoordinator::startup() { + config::ConfigRegistry::Get_Instance().register_record_config( + "ssl_client_coordinator", + [](ConfigContext ctx) { SSLClientCoordinator::reconfigure(ctx); }, + {"proxy.config.ssl.client.cert.path", + "proxy.config.ssl.server.session_ticket.enable"}); + + config::ConfigRegistry::Get_Instance().add_file_and_node_dependency( + "ssl_client_coordinator", "sni", + "proxy.config.ssl.servername.filename", "sni.yaml", false); + + config::ConfigRegistry::Get_Instance().add_file_and_node_dependency( + "ssl_client_coordinator", "ssl_multicert", + "proxy.config.ssl.server.multicert.filename", "ssl_multicert.config", false); + } + + void SSLClientCoordinator::reconfigure(ConfigContext ctx) { + ctx.in_progress(); + SSLConfig::reconfigure(ctx.add_dependent_ctx("SSLConfig")); + SNIConfig::reconfigure(ctx.add_dependent_ctx("SNIConfig")); + SSLCertificateConfig::reconfigure(ctx.add_dependent_ctx("SSLCertificateConfig")); + ctx.complete("SSL configs reloaded"); + } + +In :option:`traffic_ctl config status`, this renders as a tree: + +.. code-block:: text + + ✔ ssl_client_coordinator ················· 35ms + ├─ ✔ SSLConfig ·························· 10ms + ├─ ✔ SNIConfig ·························· 12ms + └─ ✔ SSLCertificateConfig ·············· 13ms + + +Startup vs. Reload +================== + +A common pattern is to call the same handler at startup (initial config load) and during runtime +reloads, but this is not mandatory — it is up to the developer. The only requirement is that the +handler exposed to ``ConfigRegistry`` accepts a ``ConfigContext`` parameter. + +At startup there is no active reload task, so all ``ConfigContext`` methods are **safe no-ops** — +they check the internal weak pointer and return immediately. + +This means the same handler code works in both cases without branching: + +.. code-block:: cpp + + void MyConfig::reconfigure(ConfigContext ctx) { + ctx.in_progress(); // no-op at startup, tracks progress during reload + // ... load config ... + ctx.complete(); // no-op at startup, marks task as SUCCESS during reload + } + + +Thread Model +============ + +All reload work runs on **ET_TASK** threads — never on the RPC thread or event-loop threads. + +1. **RPC thread** — receives the JSONRPC request (:ref:`admin_config_reload`), creates the reload + token and task via ``ReloadCoordinator::prepare_reload()``, schedules the actual work on + ``ET_TASK``, and returns immediately. The RPC response is sent back before any handler runs. + +2. **ET_TASK — file-based reload** — ``ReloadWorkContinuation`` fires on ``ET_TASK``. It calls + ``FileManager::rereadConfig()``, which walks every registered file and invokes + ``ConfigRegistry::execute_reload()`` for each changed config. Each handler runs synchronously. + +3. **ET_TASK — inline (RPC) reload** — ``ScheduledReloadContinuation`` fires on ``ET_TASK``. + It calls ``ConfigRegistry::execute_reload()`` directly for the targeted config key(s). + +4. **Deferred handlers** — some handlers schedule work on other threads and return before + completion. The ``ConfigContext`` remains valid across threads. The handler must call + ``ctx.complete()`` or ``ctx.fail()`` from whatever thread finishes the work. + +5. **Timeout checker** — ``ConfigReloadProgress`` is a per-reload continuation on ``ET_TASK`` + that polls periodically and marks stuck tasks as ``TIMEOUT``. + +Handlers block ``ET_TASK`` while they run. A slow handler delays all subsequent handlers in the +same reload cycle. + + +Naming Conventions +================== + +- **Registry keys** — lowercase, underscore-separated: ``ip_allow``, ``cache_control``, + ``ssl_ticket_key``, ``ssl_client_coordinator``. +- **Filename records** — follow the existing ``proxy.config..filename`` convention. +- **Trigger records** — any ``proxy.config.*`` record that should cause a reload when changed. + + +What NOT to Register +==================== + +Not every config file needs a reload handler. Startup-only configs that are never reloaded at +runtime (e.g. ``storage.config``, ``volume.config``, ``plugin.config``) do not currently need +reload handlers registered with ``ConfigRegistry``. + + +Logging Best Practices +====================== + +- Use ``ctx.log()`` for operational messages that appear in + ``traffic_ctl config status -l`` and :ref:`get_reload_config_status` responses. +- Use ``ctx.fail(errata, summary)`` when you have a ``swoc::Errata`` with detailed error context. +- Use ``ctx.fail(reason)`` for simple error strings. +- Keep log messages concise — they are stored in memory and included in JSONRPC responses. + +See the :ref:`get_reload_config_status` response examples for how log messages appear in the +task tree output. + + +Testing +======== + +After registering a new handler: + +1. Start |TS| and verify your handler runs at startup (check logs for your config file). +2. Modify the config file on disk and run :option:`traffic_ctl config reload` ``-m`` to observe the + live progress bar. +3. Run :option:`traffic_ctl config status` to verify the handler appears in the task tree with + the correct status. +4. Introduce a parse error in the config file and reload — verify the handler reports ``FAIL``. +5. Use :option:`traffic_ctl config status` ``--format json`` to inspect the raw + :ref:`get_reload_config_status` response for automation testing. + +**Autests** — the project includes autest helpers for config reload testing.
