Release 1.15.1

olp-cpp-sdk-dataservice-read

• Hotfix Reverted pull requests #1332, and #1338 as they introduced a regression which was not caught by our test suite.

Release 1.15.0

Common

• Added a new CMake option: OLP_SDK_ENABLE_ANDROID_CURL. The flag enables network layer implementation based on cURL for Android.
• Added custom certificates lookup method based on MD5 for Android cURL network layer to bypass the discrepancy between OpenSSL 1.1.1 expecting SHA1 while certificates are beeing encoded using MD5.
• Added HTTPS proxy support for the cURL network implementation.
• Increased required minimal version for cURL from 7.47.0 to 7.52.0 due to the HTTPS proxy support.
• Fixed the falsely returned errors from olp::client::OlpClient::CallApi. The olp::client::OlpClient::CallApi now propagates the correct errors from the olp::authentication::TokenProvider.
• Replaced usage of std::stol with std::stoll for LRU expiration time evaluation.

olp-cpp-sdk-dataservice-read

• Added the olp::dataservice::read::VersionedLayerClient::QuadTreeIndex API. Use this API to query the partitions for the specified tiles provided by olp::dataservice::read::TileRequest.
• The olp::dataservice::read::PartitionsCacheRepository::FindQuadTree now reads the data from the cache starting from the lowest level first, which improves performance as the quadtrees are usually loaded 4 levels lower then the requested tile.
• The olp::dataservice::read::CatalogClient::GetCatalog now forms correct URL when custom olp::client::CatalogEndpointProvider is used.
• Fixed the broken chain of cancellation contexts inside olp::dataservice::read::VersionedLayerClient::PrefetchTiles method. The ongoing prefetch request can now be cancelled much faster, which avoids waiting for the ongoing sub-tasks to finish until the entire operation is cancelled.

olp-cpp-sdk-authentication

• Added optional device_id field to the olp::authentication::AuthenticationClient::SignInProperties. This field can be used for the OAuth rate limiting per device supported by the HERE OAuth service.
