This new code can be used for rendering on the Main thread
while it will also work for rendering on the Map thread
before we make the switch. Needed by #2909.
Simplify LatLng::{wrap,unwrapForShortestPath} code, avoiding duplicated
code between Transform::{latLngToScreenCoordinate,easeTo,flyTo}.
Added unit tests for camera usage in Transform to detect cases like e.g.
crossing the antimeridian as a shortest path between two coordinates.
Transform::flyTo precision loss to be handled in #4298.
- Make returning LatLngs unwrapped by default.
- PointAnnotation and ShapeAnnotation are always wrapped so they can be
selected via intersection from the visible tile boundaries.
- Fixes LatLng::wrap() calculation.
- Fixes LatLng::unwrapForShortestPath() calculation.
The new unwrapForShortestPath algorithm unwraps the start coordinate
either forwards or backwards depending on the end coordinate value, so
we can always cross the antimeridian when needed and still obtain a
wrapped end coordinate in the end.
Fixes#4214.
If the server keeps sending replies considered from the client in the
past (there is no way to tell if the server or client clock is wrong),
the client will try to interpolate a valid expiration time based
on the delta of the expiration intervals sent by the server.
If the intervals are always the same, exponential backoff kicks in
until we get a different expiration time from what we already have.
When inserting an cached resource, or removing a region, remove least-recently used resources and tiles, not used by offline regions, until the used database size, as calculated by multiplying the number of in-use pages by the page size, is less than the maximum cache size minus 5 times the page size.
In addition, OfflineDatabase may be configured to ignore cache puts of individual resources larger than a certain size.
This policy is similar but not identical to the former SQLiteCache policy:
* It accounts for offline, by exempting resources required by offline regions from eviction.
* It must delete from two tables (resources and tiles), rather than one. Currently the strategy is naive: evict 50 rows at a time from each table.
* It makes maximumCacheSize and maximumCacheEntrySize completely independent. The SQLiteCache implementation evicted when `usedSize > maximumCacheSize - 2 * maximumCacheEntrySize`. This evicts when `usedSize > maximumCacheSize - 5 * pageSize`.
* It uses a non-unlimited default value for maximumCacheSize: 50 MB. We should have always had a limit in place; "a cache without an eviction policy is a resource leak".
Implicit bool conversions are bad; they'll be used e.g. for a == b and a != b if those operators are not defined. This was happening at 032c8fba3c/src/mbgl/map/transform.cpp (L132-L132), for example.
* Use "named constructors": empty, world, hull
* Make the two-argument constructor lenient (i.e., it is a hull operation)
* Add various accessors
* Enforce a single empty representation
Should not be used at all, added for a corner case
on OSX network backend where the request is processed on
a worker thread managed by OSX and we need to wait for
that reply before destroying the thread that pushed the
request.
This reverts commit 6709bdcacd.
There was an issue with the script that removes '-lwebp' from WebP
linker flags, since we're statically linking. This is now fixed.
Moved EdgeInsets to geo.hpp so CameraOptions and Transform can refer to it. Added a padding option to CameraOptions that alters the frame of reference for the center option. Added optional padding parameters to LatLng getters and setters.
Working towards #2600.
* Standardize on std::exception_ptr as the error representation
(fixes#2854).
* Don't format textual strings at the error source; pass on the
constituent data via observer method parameters instead.
* Use the null object pattern to simplify observer notification code.
* Further refactoring for ResourceLoading tests.
