Added aliases for std::chrono typedefs (eg. 'Seconds' for
std::chrono::seconds). These aliases are used together with templated
helper functions to replace time_t with std::chrono::seconds for most
cases, in particular for 'modified' and 'expires' values in Response.
It's a premultiplied image. This implies that we were misusing encodePNG
in most cases, as we were passing premultiplied pixels which were then
interpreted as unmultiplied. I changed encodePNG to accept premultipled
pixels, and unpremultiply in the implementations.
ConstrainMode gives flexibility to our engine to choose between
constraining both vertically and horizontally, or just vertically
(default behavior).
Constrain in both axis means we can no longer pan the map beyond the map
boundaries. This fixes an issue where e.g. annotations disappear upon
crossing the map boundaries.
LatLngBounds southwest and northeast coordinate points were inverted, so
they could be extended via LatLngBounds::extend(). However, this looks
confusing and error-prone.
A static LatLngBounds::getExtendable() is added to address cases when we
want to extend LatLngBounds.
- [osx] set -fvisibility-inlines-hidden in gyp/common.gypi to silence
mismatched visibility linker warnings
- [linux] set cxx_host in GYP_FLAGS to set -fabi-version=0 on gcc builds
to use clang-built mason binaries
- [ios] update symbol visibility for iOS tests
- [ios] link libgeojsonvt.a in iOS tests xcodeproj
- add libgeojsonvt.a to General -> Linked Frameworks and Libraries
- add mason_packages (recursive) to Build Settings -> Library Search Path
- [ios] add libuv and geojsonvt first in iOS libtool smush to ensure symbols
are found by later compilation units where they are undefined
We're now reparsing tiles when they expire. We're also swapping out buckets atomically to avoid flickering data; i.e. we're displaying the old data as long as we don't have a new parsed bucket for that layer yet. The parsed buckets now live in the *TileData objects rather than in the TileWorker; only partially parsed == pending buckets will remain in the TileWorker. Once they're parsed, they're moved to the *TileData object.
When we get a request with an explicit expiration time, we're now starting a timer, and will trigger a refresh once the data expires. This gives requesters a chance to update their data.
We're now returning stale responses from cache. Those responses will have the `stale` flag set to true. Currently, all requesters in the core code discard stale responses, and cancel the request immediately after they got a non-stale response.
By not automatically destroying Request objects after the result has been delivered, we are making sure that we can potentially fire the callback multiple times without adverse effects. This means that you have to hold on to the result of fs->request(), can explicitly cancel it if you don't want to be notified of data changes anymore. Not doing so will monitor the request indefinitely and will prevent the app from exiting.
MapData was needed for two things: getting the default transition and
fade durations, and detecting still rendering vs. continuous.
The first is avoided by making transition durations optional, and
supplying the default fallback value at evaluation time. The second did
not fix the still rendering issue, and will be followed up with a
different approach in a later commit.
Adding new mbgl::GLContextMode enum to mbgl::Map ctor, which gets stored
in MapData. In shared GL context environments, we cannot assume that the
GL state that has been left since the last draw is the same, so we reset
the GL configurations to their default values.
