* chore: couple of updates to fix cargo audit job
- remove humantime ignore in deny.toml
- update pyo3 to use 0.24.1 (https://rustsec.org/advisories/RUSTSEC-2025-0020.html)
* chore: moved pyo3 version to root cargo.toml
* feat: Add request plugin capability
Adds the request plugin type. Triggers can be bound to an API endpoint at /api/v3/engine/<path>. Requests will get yielded to the plugin with the query parameters, request parameters, and request body.
I didn't implement the test endpoint for this plugin type as it seems much more natural for users to save the file and make a new request. Once #25863 is done it'll make it very easy.
Closes#25862
* chore: fix spelling in error message
* feat(processing_engine): Add cron plugins and triggers to the processing engine.
* feat(processing_engine): switch from 'cron plugin' to 'schedule plugin', use TimeProvider.
* feat(processing_engine): add test for test scheduled plugin.
* feat: return better plugin execution errors
This sets up the framework for fleshing out more useful plugin execution errors that get returned to the user during testing. We'll also want to capture these for logging in system tables.
Also fixes a test that was broken in previous commit on time limits. Didn't show up because of the feature flag.
* fix: compile errors without system-py feature
This allows the user to specify arguments that will be passed to each execution of a wal plugin trigger. The CLI test was updated to check this end to end.
Closes#25655
* feat: Update WAL plugin for new structure
This ended up being a very large change set. In order to get around circular dependencies, the processing engine had to be moved into its own crate, which I think is ultimately much cleaner.
Unfortunately, this required changing a ton of things. There's more testing and things to add on to this, but I think it's important to get this through and build on it.
Importantly, the processing engine no longer resides inside the write buffer. Instead, it is attached to the HTTP server. It is now able to take a query executor, write buffer, and WAL so that the full range of functionality of the server can be exposed to the plugin API.
There are a bunch of system-py feature flags littered everywhere, which I'm hoping we can remove soon.
* refactor: PR feedback
This ended up being a couple things rolled into one. In order to add a query API to the Python plugin, I had to pull the QueryExecutor trait out of server into a place so that the python crate could use it.
This implements the query API, but also fixes up the WAL plugin test CLI a bit. I've added a test in the CLI section so that it shows end-to-end operation of the WAL plugin test API and exercise of the entire Plugin API.
Closes#25757
* Move processing engine invocation to a seperate tokio task.
* Support writing back line protocol from python via insert_line_protocol().
* Update structs to work with bincode.
