Erica Fischer 2d548bed06 Infinite loop fixes, minimizing changes to behavior (#345)
* Divide-and-conquer polygon cleaning

* Catch the case where the gap can't be increased further

* Catch the case where we try to keep impossibly many features

* Make label points earlier in the tiling process

* Another case where it could try to drop even after already limiting.

* And do not coalesce on impossibly small geometries

* Add missing return

* Update version and changelog

Erica Fischer 5b18eea673 Work in progress on binning features in overzoom (#258)
* Factoring out tilestats management from GeoJSON file reading

* Move code around so overzoom can link against parse_layers

* Read the file of bins

* Plumb the bins through to overzoom()

* Some zip code bins to test with

* (Currently non-functional) test of binning

* Starting to spell out the bin matching loop

* Can't flatten points, so don't flatten bins either

* More fleshing out bin traversal

* Bounding box of tile-relative mvt geometry

* Smallest enclosing tile from bbox

* Most of the bin scan

* Add point in polygon check. It crashes.

* Find the matching bins

* GDAL-style bounding boxes have eaten my brain

* Make some features to bin into

* Increment a count as features are found to be within the bins

* Fix longitude wraparound in overzoom bins

* Fix the tests

* Push off attribute copying until after bin assignment

* Carry sum of numeric attributes into the bins

* Also add mean, min, and max

* Add --calculate-feature-index since I keep needing it for testing

* Add an option to accumulate sum/mean/max/min/count of all numeric attrs

* Don't bake in tippecanoe:mean, since we redo it from sum and count

* Forgot to update this test fixture after removing tiled mean

* Update version and changelog

Erica Fischer 47e774adc4 Improve the appearance of coalesce-densest-as-needed tiles (#247)
* Start to distinguish fixed cluster density setting from as-needed density

* Make consistent {drop,coalesce}-densest decisions between zooms

* Actually track the previous index instead of just intending to

* Clean up collinearities in coalesced features

* To determine densest, look at actual physical distance, not just index

* Don't actually need the previous index in serial_feature now

* Center of mass of one feature to most distant point of the next

* Add apologetic comment

* Wait, how did the tests pass before?

* Revert "Wait, how did the tests pass before?"

This reverts commit f73c8ee543.

* Add --maximum-string-attribute-length option

* Update version and changelog

* A little more testing to make sure

Erica Fischer 4e52cbd957 Drop or retain whole multiplier clusters when dropping as needed (#198)
* Prep to track conditions other than just "dropped" or "kept"

* Count up instead of down

* Drop or retain whole multiplier clusters based on their first feature

* Calculate a global feature dropping sequence

* Switch over to using the drop sequence for drop-fraction

* Remove unused arguments for the old drop-fraction implementation

* Fix copy-and-paste bugs, update tests

* Properly incorporate feature_minzoom into the drop sequence, I hope

* Rename drop_by to drop_sequence

* See if sorting within clusters fixes filter stability between zooms

* Remove very chatty debug print

* Update changelog and version

* Use named constants instead of numbers for feature dropping/keeping

* Add comment to explain purpose and method of bit reversal

Erica Fischer cc5c1c79df Speed up overzooming in tile-join (#147)
* Clip away entire features by bbox. Avoid unnecessary recompression.

* Move parent tile decoding in tile-join out of overzoom proper

* An ever-growing cache of parent tiles

* Limit the size of the cache

* Remove the current reader *before* checking if we can run the queue

* Clean up

* Add missing #include

* Add comment

* When the tile-join cache fills up, evict the least recently used

* Fix microsecond math

* Factoring out tile-join's cache for testing

* Add unit tests for tile-join cache

* Update changelog and version

Erica Fischer 26bf08deb2 Externalizing polygon shard detection (#146)
* Start of externalizing polygon shard detection

* Completely untested external quicksort

* Add unit test for external quicksort

* Remember to clean up temporary files

* Sort and scan the vertices

* Bring over more vertex logic

* Make nodes from vertices

* Checkpoint on switching over to global shared nodes

* Do the thing

* Revert unintended change to coalesced linestring behavior

* Take shared nodes into account in early simplification

* Let it do more sorting in memory

* Fix overnoding of collinear linestrings

* Remove duplicate nodes, since only duplicate vertices now matter

* Remember to delete temporary files

* Fix out of bounds memory access below, apparently

* Fix the actual undefined behavior

* Still running out of memory in one case. Find out where.

* Forgot the conditional

* Try again to make it not run out of memory

* Update version and changelog
