* [core] Fix potential race condition crash in symbol querying..Chris Loer2018-03-292-8/+25
| | | | | | Second half of fix for issue #11538. If a global placement took place between the time a tile's non-symbol layout updated and the time new symbol buckets arrived, the tile's new FeatureIndex would be committed, but the global CollisionIndex would be generated against the old symbolBuckets. The mismatch could cause the CollisionIndex to contain indices that didn't exist in the new FeatureIndex, and attempting to access them would generate an out-of-bounds exception.
* [core] Fix potential race condition crash in symbol querying..Chris Loer2018-03-292-6/+8
| | | | | | | | First half of fix for issue #11538. Testing `if (pendingData)` didn't work if there _was_ a data update, but the update was "the data for this tile is now null". In that case, the tile's FeatureIndex would be updated, but the tile's data member would remain unchanged. In the case of a tile's data being deleted, the matching FeatureIndex would have an empty set of bucketLayerIDs, but the _old_ data would still be in place for querying, and the symbolBuckets might not be updated yet (pending onPlacement). In this case `bucketLayerIDs.at(indexedFeature.bucketName)` could throw an out-of-range exception.

* [core] Implement Expression::serialize()Chris Loer2018-02-2810-23/+177
| | | | | | | | Issue #10714 - Each expression stores its operator as a string, and default serialization is [operator, serialize(child1), ...] - Custom implementations of `serialize` for Expression types that don't follow the pattern - expression::Value -> mbgl::Value converter - node_expression bindings to expose `serialize`
* [core] continue loading style even if we mutate itKonstantin Käfer2018-02-231-5/+0
| | | | When we load a stale style from cache, and the user immediately starts mutating it, we should continue loading the style so that we'll get a fresh copy of the data into our cache and avoid perpetually showing the stale style.

* [core] don't force downloading of Open Sans fontsKonstantin Käfer2018-01-251-1/+1
| | | | When a SymbolLayer doesn't have a text-font defined, we automatically add Open Sans/Arial Unicode MS. However, when the SymbolLayer is only used for rendering icons, it doesn't have text-field defined either. In those cases, we still force downloading Open Sans/Arial Unicode MS during offline pack creation. If the user doesn't use this font, this change should save ~15MB and a few seconds in download time.

Implemented conversions from NSExpression to JSON arrays and vice versa. The most common NSExpression functions are now converted into style expressions, but not all of the most common style expression operators are supported yet. * [ios, macos] Implemented string coercion * [ios, macos] Color literals * [ios, macos] Null constant expressions * [ios, macos] Convert dictionary literals * [ios, macos] Interpolation expressions * [ios, macos] to-boolean, to-number, get from object * [ios, macos] Variable expressions Implemented custom expression functions for assigning and referring to variables within the context of an expression. Variables are assigned via a “context dictionary” and applied to an subexpression that is given as another argument to the same expression. Also implemented built-in variable expressions for zoom level and heatmap density. * [ios, macos] Convert colors, offsets, padding in expressions to JSON objects * [ios, macos] Expression-based style property getters Implemented a conversion from mbgl::style::PropertyValues to Objective-C JSON objects, which are then converted to NSExpressions. * [ios, macos] Consolidated property value–expression conversion in MGLStyleValueTransformer * [ios, macos] Predicate and expression guide Extracted documentation about predicates from a documentation comment in MGLVectorStyleLayer.h to a new jazzy guide. Added details about NSExpression support as well. Began updating the “For Style Authors” guide to reflect the transition from style values to expressions. * [ios, macos] Updated style authoring guide Updated the Information for Style Authors guide to discuss expressions instead of style functions. Included a table mapping style specification expression operators to NSExpression syntaxes. * [ios, macos] Migrated codegen templates to expressions * [ios, macos] Applied expression changes via codegen Ran make darwin-style-code. * [macos] Migrated macosapp to expressions * [ios, macos] Updated style function guide This guide needs to be thoroughly rewritten, but for now the example code has been migrated to expressions. * [ios, macos] Eviscerated style function tests * [ios, macos] Updated changelogs * [ios] Migrated iosapp to expressions * [ios, macos] Exposed JSON conversion methods publicly * [ios, macos] Removed MGLStyleValue, MGLStyleFunction

* [core] Prevent symbols at the same zoom from sharing a crossTileID.Chris Loer2018-01-172-9/+35
| | | | | Port of GL JS PR #5994. Fixes issue #10844, which would allow multiple symbols in a tile to share the same crossTileID as one of their duplicate parent-tile symbols. Once the symbols shared a crossTileID, they would permanently remain "duplicates" of each other, even after increasing zoom level allowed the CrossTileSymbolIndex to distinguish between them.
