UPDATE: this release has a minor bug in mbtiles utility, fixed in subsequent release

martin

• Add runtime for AWS Lambda by @jleedev in https://github.com/maplibre/martin/pull/1127
• Add --preferred-encoding (gzip|brotli) to use when tile is not pre-encoded by source by @sharkAndshark in https://github.com/maplibre/martin/pull/1189
• Switch default encoding to gzip for now by @nyurik in https://github.com/maplibre/martin/pull/1260
• Fix preferred encoding computation by @nyurik in https://github.com/maplibre/martin/pull/1355
• add application_name to PG connection by @nyurik in https://github.com/maplibre/martin/pull/1325
• Fix martin --auto-bounds silently ignored with --config by @nyurik in https://github.com/maplibre/martin/pull/1223

martin-cp

• Add martin-cp to homebrew by @sharkAndshark in https://github.com/maplibre/martin/pull/1126

mbtiles

• New mbtiles diff command aliasing mbtiles copy --diff-with-file by @sharkAndshark in https://github.com/maplibre/martin/pull/1068
  • And improve diff cmd with copy opts by @nyurik in https://github.com/maplibre/martin/pull/1183
• Add binary diff support for mbtiles by @nyurik in https://github.com/maplibre/martin/pull/1358
  • mbtiles diff now has an additional --patch-type param with whole, bin-diff-raw and bin-diff-gz values:
    • whole stores different tiles as before - as whole tiles in the tiles table
    • bin-diff-raw computes binary difference between tiles, and stores them as brotli-encoded value in a bsdiffraw table, together with a xxh3_64 hash of the tile as it will be stored after patching
    • bin-diff-gz same as bin-diff-raw, but assumes the tiles are gzip-compressed, so it uncompresses them before comparing. The xxh3_64 stores the hash of the uncompressed tile. The data will be stored in the bsdiffrawgz table (identical structure with above)
  • mbtiles copy --apply-patch will automatically detect if bsdiffrawgz or bsdiffraw tables exist, and will use binary patching.
  • mbtiles apply-patch does not support binary patching yet
  • mbtiles copy --diff-with-file ... --patch-type ... is an alias to mbtiles diff --patch-type ...
• bug: ensure agg_tiles_hash_after_apply is added even on empty mbtiles by @nyurik in https://github.com/maplibre/martin/pull/1242

Tile Caching

• Implement tile caching by @nyurik in https://github.com/maplibre/martin/pull/1105

Add a top level config parameter -- the size of cache memory (in MB) to use for caching tiles and PMT directories, defaulting to 512, and 0 to disable. This also removes the pmtiles.dir_cache_size_mb parameter (it will be ignored, but will give a warning)

cache_size_mb: 512

The new cache will contain all tiles as provided by the source. So if PostgreSQL returns a non-compressed tile, the cache will contain the uncompressed variant, and will be compressed for each response. This will be fixed in the later releases.

Note that fonts and sprites are not cached at this time, and are still a TODO.

Internal

• Fix sporadic macos test failures by @nyurik in https://github.com/maplibre/martin/pull/1104
• Lots of small refactorings by @nyurik in https://github.com/maplibre/martin/pull/1107

Full Changelog: https://github.com/maplibre/martin/compare/v0.12.0...v0.13.0

Cached PMTiles with HTTP support

Martin now supports cached local and HTTP PMTiles sources. Additionally, multiple PMTiles sources share a single web client instance, optimizing connection reuse in case multiple pmtiles reside on the same host. Implemented by @nyurik with great help from @kyleslugg who did the integration testing CI work, see https://github.com/maplibre/martin/pull/991, https://github.com/maplibre/martin/pull/1095, https://github.com/maplibre/martin/pull/1094

pmtiles:
  # Memory (in MB) to use for caching PMTiles directories [default: 32, 0 to disable]] 
  dir_cache_size_mb: 100
  paths:
    # scan this whole dir, matching all *.pmtiles files
    - /dir-path
    # specific pmtiles file will be published as a pmt source (filename without extension)
    - /path/to/pmt.pmtiles
    # A web server with a PMTiles file that supports range requests
    - https://example.org/path/tiles.pmtiles
  sources:
    # named source matching source name to a single file
    pm-src1: /path/to/pmt.pmtiles
    # A named source to a web server with a PMTiles file that supports range requests
    pm-web2: https://example.org/path/tiles.pmtiles

martin-cp and mbtiles improvements

• martin-cp will now update min/max zoom levels after copying to an mbtiles file, but only if the existing metadata min/max zooms do not include the tiles actually contained in the file by @nyurik in https://github.com/maplibre/martin/pull/1096
• mbtiles update now allows different types of zoom updates - reset to content, grow only, or skip (dry run) by @nyurik in https://github.com/maplibre/martin/pull/1096

Martin as a Reusable Crate

Martin has been refactored to allow modular reuse to be more of a library in your own Rust application. When used as a library, you can use the following features to limit which backends are compiled by @nyurik in https://github.com/maplibre/martin/pull/1097 and https://github.com/maplibre/martin/pull/1094

• postgres - enable PostgreSQL/PostGIS tile sources
• pmtiles - enable PMTile tile sources
• mbtiles - enable MBTile tile sources
• fonts - enable font sources
• sprites - enable sprite sources

Full Changelog: https://github.com/maplibre/martin/compare/v0.11.6...v0.12.0

What's Changed

• Multiple mbtiles and martin-cp fixes by @nyurik in https://github.com/maplibre/martin/pull/1083
  • BREAKING: martin-cp will now set format=pbf instead of mvt. This is what QGIS and possibly others expect, and this is what tools like tilelive generates.
  • martin-cp sets minzoom and maxzoom metadata values based on the zoom parameters
  • Add mbtiles meta-update command to refresh zoom levels based on the present tiles.

Internal Changes

Breaking Changes

Auto bounds calculation methods

• Remove --disable-bounds flag and disable_bounds config parameters.
• Add --auto-bounds / -b CLI parameter and auto_bounds config value:
  • quick: Compute table geometry bounds, but skips it if it takes longer than 5 seconds (default)
  • calc: Compute table geometry bounds. The startup time may be significant. Make sure all GEO columns have indexes
  • skip: Skip bounds calculation. The bounds will be set to the whole world
• -b is now mapped to --auto-bounds param, but it will fail if used by itself because it now requires a value.

What's New

Sprite serving

Dynamic sprites support was added by @nyurik in https://github.com/maplibre/martin/pull/715. Given a directory with SVG images, Martin will dynamically generate a sprite index and a PNG image, for both low and high resolution displays. This feature is made possible by the spreet crate from @flother (thank you!). Per MapLibre sprites API, the new feature supports

• /sprite/<sprite_id>.json metadata about the sprite file - all coming from a single directory
• /sprite/<sprite_id>.png all images combined into a single PNG
• /sprite/<sprite_id>@2x.json same but for high DPI devices
• /sprite/<sprite_id>@2x.png

copy mbtiles tool

mbtiles tool now lets users partially copy an mbtiles file, filtering to specific zooms, and to convert de-duplicated to a flat mbtiles format.
