This extracts some of the code from #511 but without breaking changes
* Use `PathBuf` instead of `String` where dealing with files
* Parse keep_alive as u64
* More config tests to crash if martin output contains warnings or
errors
Can now handle several additional Postgres functions to get a tile, plus
tons of small fixes
### Multiple result variants
* `getmvt(z,x,y) -> [bytea,md5]` (single row with two columns)
* `getmvt(z,x,y) -> [bytea]` (single row with a single column)
* `getmvt(z,x,y) -> bytea` (value)
### Multiple input parameter variants
* `getmvt(z, x, y)` or `getmvt(zoom, x, y)` (all 3 vars must be
integers)
* `getmvt(z, x, y, url_query)`, where instead of `url_query` it could be
any other name, but must be of type JSON
### Breaking
* srid is now the same type as PG -- `i32`
* renamed config vals `table_sources` and `function_sources` into
`tables` and `functions`
### Features and fixes
* if postgis is v3.1+, uses margin parameter to extend the search box by
the size of the buffer. I think we should make 3.1 minimal required.
* fixes feature ID issue from #466
* fixes mixed case names for schemas, tables and columns, functions and
parameter names per #389
### Notes
* More dynamic SQL generation in code instead of using external SQL
files. Those should only be used when they are not parametrized.
* The new function/table discovery mechanism: query for all functions in
the database, and match up those functions with the ones configured (if
any), plus adds all the rest of the un-declared ones if discovery mode
is on.
* During table and function discovery, the code generates a map of
`(PgSqlInfo, FunctionInfo)` (or table) tupples containing SQL needed to
get the tile.
* Auto-discovery mode is currently hidden - the discovery is on only
when no tables or functions are configured. TBD - how to configure it in
the future
* The new system allows for an easy way to auto-discover for the
specific schemas only, solving #47
* predictable order of table/function instantiation
* bounding boxes computed in parallel for all tables (when not
configured)
* proper identifier escaping
* test cleanup

Partial implementation of the #430
* New endpoint structure:
* `GET /` -- a placeholder for the future home page
* `GET /catalog` -- get a list of available sources, as a list of json
blobs.
* `[{id, name, description, attribution, vector_layer}, ...]` (some
fields might be missing)
* `GET /<id>` -- get tilejson for the given source, or a combination of
sources. No `.json` extension
* `GET /<id>/<z>/<x>/<y>` -- get a tile. No format extension.
* `GET /health` -- healthcheck
* Introduce a new tile format support crate (using code from the
maplibre/mbtileserve project)
* Removed the `/rpc/...` routes - all source IDs are accessed in the
same way
* Can print auto-generated configuration or save it to a file
* Refactored to support multiple sources from multiple backends, with a
proper naming conflict resolution
TODO:
* benchmarks need to be rewritten - they were relying on some internal
structures that are no longer there. This might be done as a separate PR
due to a very different internal architecture - might need to rethink
benchmarking approaches.
By default, Martin is now compiled without openssl, simplifying
debugging and simple case usage, whereas the docker build and CI
publishing would still use openssl
* remove most of the utils:: and dev:: namespace usage
* rename `configure_db_source` to `configure_db_sources`
* use defaults from other table info objects (using the `..obj` syntax)
* use doc comments vs regular comment in a few places
* refactor server_test.rs to make it more readable and much shorter
* use a macro for identical code
* use a test_get() for identical GET request
* rename fn test_foo() into fn foo() for simplicity
Getting ready for multi-backend system, where each backend would have its own configuration.
All 3 config structs (clap args, config, and configbuilder) are now separated into 3 files - the main one, one for service (actix stuff), and one for PostgreSQL.
The files have been moved to `/pg` and `/srv`, but otherwise the logic should be mostly intact.
* Use latest Clap-derive (currently v4rc, but should be public within a few days)
* reorganize configuration to streamline different config sources into one Config (using multiple ConfigBuilders)
* remove all actions and other low-level magic code, making it more straightforward for the most common usage
* replace r2d2 with bb8 to make it all async
* use first significant version in cargo.toml - this makes it easier to maintain
This fixes#349
