Sourcing files that set flags bleed into Travis' wrapper script, which
messes with their workflow, e.g. preventing after_failure scripts from
triggering.
These changes fix that:
* Move exported variables from install.sh to setup.sh, so install.sh
doesn't have to be sourced.
* Source setup.sh from run.sh, rather than directly from .travis.yml.
In addition, as a good practice, remove `set -e` etc. from setup.sh,
and add a comment not to add them back. It's the sourcing script's
responsibility to set these flags.
If the request is cancelled, the response callback won't be called, and
~Source ensures that the request is cancelled. So it's safe to bind
`this` in the lambda.
In order to calculate the collision correctly, the layer ordering
matters. Because of that, when we find the first incomplete symbol
bucket, we stop processing any furter SymbolBucket.
The side effect of this change is, if the first SymbolBucket is the
last to receive its resources, we won't see any label at all on
the screen until the last moment, when everything will be draw at
once.
We keep the Collision object alive longer because we need it
for the SymbolBuckets yet to be created in case more data
resources arrive. When the tile is no longer needed or if it
is completely parsed or obsolete (i.e. in a immutable state)
we throw the Collision object away.
Also add a virtual setState() method to give subclasses a chance
to intercept the change of state. This will be used by VectorTileData
to release resources when the TileData becomes immutable.
Enable Mapbox Metrics by default when Settings.bundle is absent, but allow Settings.bundle to override the default. Don’t register defaults for non-Mapbox preferences. The two-phase registration ensures that the defaults don’t default to unexpected values, yet gives the developer a chance to call `+[MGLAccountManager mapboxMetricsEnabledSettingShownInApp]` before the hard assertion.
Fixes#1518.
`MGLMapboxEvents` automatically recreates its location manager when the host app is reauthorized for Location Services. Added some redundancy to ensure that there is no location manager when either Location Services or Mapbox Metrics is off.
As soon as the user returns to the host app after changing the opt-out preference in Settings, `MGLMapboxEvents` responds by pausing or resuming. Also moved the IB designables agent check to occur only once, at launch, since the process name is not expected to change mid-session.
