Important

A discussion is underway on what features or changes are needed before we consider a 1.0 release. If you have thoughts, suggestions, or feature requests, please join the conversation and help guide the future of Martin.

What's Changed

Metrics

We have added an metrics endpoint. 🎉
Due to issues with content encoding, the metrics are at /_/metrics instead of the more common /metrics

We currently publish the following metrics:

martin_http_requests_duration_seconds HTTP request duration in seconds for all requests => Response time histogram
martin_http_requests_total Total number of HTTP requests => Request count

Done by @lefuturiste in #793

Tip

If you have a need/want for more metrics, we would encourage you to open an issue.
We know that these metrics are likely not enough for good monitoring

Adding a frontend

During this Release cycle we spend lots of our effort on building a frontend into Martin.

Important

The frontend is only enabled for the public if you have --webui enable-for-all set.
The default is currently --webui disable.

We plan on either changing this default to be --webui enable-for-localhost or allowing to move the webui, metrics and all other "admin"-features to another port for simpler deployment.

Features:

see basic metrics
inspect tiles
view styles with mapunik as an add-on
view sprites
view fonts

Screenshots:

Note

🚧 The frontend (like all other features) is not final. 🚧
If you have ideas how Martins frontend could improve YOUR workflow, we would love issues or slack comments.
Pull requests are also more than welcome

Dark mode

Light mode

Features have been cut from this release:

A better integration with mapuntik where styles can be actually edited back to disk without needing to click the download button
Fonts being previewable
An interactive demo how sdf sprites work

Bugfixes

fix(pg): When there are column comments, it will prompt for duplicate table by @huanglii in #1891
fix(pg): handle SRID 4326 bbox tiles spanning over the antimeridian by @todtb in #1910
Improves tile query bounding box calculation in table_to_query by applying buffer margins correctly for SRID 3857 (already supported) and 4326 (new) .
For SRID 4326, this uses ST_Expand with degree-based margins to fix antimeridian edge cases.

fix(martin-cp): improve the invalid bbox error message by @CommanderStorm in #1995
