v1.11.0 (02/08/2020)

Common

  • Added API to the olp::cache::DefaultCache to get or set the size of the mutable cache. Now you can increase or decrease the disk cache size during runtime. Please note that when setting a smaller size then the current size, the eviction of data will be triggered which can take some time.
  • Added API to the olp::cache::DefaultCache to get size of protected cache.
  • Fixed incorrect olp::thread::ThreadedTaskScheduler behaviour to copy tasks instead of moving them.
  • Fixed the incorrect reset of the olp::client::CancelationContext in the olp::client::TaskContext that could lead to resource leaking and unexpected network requests cancelation.
  • Updated the lookup API endpoint for here-dev partitions from in.here.com to sit.here.com.

olp-cpp-sdk-dataservice-read

  • Fixed the data races inside prefetch operation that could lead to double callback or no callback at all.
  • Fixed prefetch cancelation behavior for both olp::dataservice::read::VersionedLayerClient and olp::dataservice::read::VolatileLayerClient. When canceled before this fix user will not know the status for each tile, in particular, that were canceled and only received the status for the tiles which succeeded or which failed with an arbitrary error.

v1.10.0 (12/14/2020)

Common

  • Ported the std::shared_mutex class from the C++17 Standard Library to use it in C++11/14 code.
  • Added the logging status of the network requests on the iOS platform. Now, you can see an HTTP return code for each completed request in logs.
  • Fixed the proxy warning message on the Android platform.
  • Added the Open and Close APIs to olp::cache::DefaultCache. You can use them to open or close individual caches.
  • olp::client::ApiLookupClient now caches the olp::client::OlpClient instances internally. It enables the merging of the same URL requests inside the olp::client::OlpClient instance.
  • Added merging of the same requests to the olp::client::OlpClient class. Internally, it merges the same requests by a URL when the payload is empty.
  • Removed the unnecessary sleep, which forced all requests to be at least 100 ms, from olp::http::NetworkCurl. 2-second sleep can still occur when there are no used handles.
  • Added downloaded size and time of execution to logs for completed requests in olp::http::NetworkCurl. Now, upon completion, you can see how much data was downloaded and how long the request took.

olp-cpp-sdk-authentication

  • Added the GetMyAccount API to olp::authentication::AuthenticationClient. It can retrieve user information based on a valid access token previously requested by the user upon sign-in.
  • Added the olp::authentication::Crypto class. It exposes the SHA256 and HMAC-SHA256 algorithms used by the module internally.

olp-cpp-sdk-dataservice-read

  • Fixed the data race inside the olp::client::TaskSink class. The data race occurred when a task added another task while the destruction was ongoing and then crashed.
  • Adapted olp::dataservice::read::StreamLayerClient and olp::dataservice::read::CatalogClient to use olp::client::TaskSink.
  • Fixed the expiration duration of the latest version. The user-provided expiration duration was not propagated to the cache.
  • Merged the same concurrent GetPartitions requests in the olp::dataservice::read::VersionedLayerClient.
  • Various changes in logging; decreased the level of messages to reduce the output.

v1.9.0 (10/12/2020)

Common

  • The default logger now adds a timestamp to logs.
  • Fixed a crash in the olp::cache::DefaultCache::Put method that occurred when the input value was null.
  • Fixed the HTTP response error that occurred when the request was canceled during the network shutdown on Windows.
  • olp::thread::TaskScheduler now supports tasks with priorities. Tasks with higher priority are executed first.
  • Fixed the issue that occurred when the JSON parsers produced valid empty objects.

olp-cpp-sdk-dataservice-read

  • Fixed the behavior of the GetAggregatedData and PrefetchTiles APIs for both olp::dataservice::read::VersionedLayerClient and olp::dataservice::read::VolatileLayerClient. When the aggregated parent tile is far away, i.e. more then max. depth 4, other APIs could not find it (for example, level 14 tile aggregated on level 1). Now, the aggregated tile can be found and used by other APIs.
  • PrefetchTilesRequest, TileRequest, and DataRequest now support priorities.
  • Fixed the crash that occurred when the client was destroyed during an ongoing prefetch operation.
  • Changed the behavior of olp::dataservice::read::CatalogClient::GetLatestVersion and olp::dataservice::read::VersionedLayerClient. Now, if you do not specify a version, the SDK tries to get it from the network by default. Also, in the cache, the latest version now does not expire after five minutes.
  • Added new API olp::dataservice::read::VersionedLayerClient::PrefetchPartitions which allows you to prefetch generic partitions which are not tile based.

olp-cpp-sdk-dataservice-write

  • Fixed the uploading of encoded data to the HERE Blob Service. The missing Content-Encoding header is now added when the layer is configured as compressed. This applies to olp::dataservice::write::VersionedLayerClient, olp::dataservice::write::VolatileLayerClient and olp::dataservice::write::IndexLayerClient.
  • Fix the bug in the olp::dataservice::write::StreamLayerClient::PublishData when the TraceId provided by the user is ignored for data bigger than 20 MB.
  • Work In Progress Enhanced olp::dataservice::write::VersionedLayerClient. The PublishToBatch and CancelBatch methods now use olp::thread::TaskScheduler instead of network threads for asynchronous operations.
  • Work In Progress Enhanced olp::dataservice::write::VolatileLayerClient. The PublishPartitionData method now uses olp::thread::TaskScheduler instead of network threads for asynchronous operations.

v1.8.0 (08/25/2020)

  • Enhanced prefetch. Now, you can request quadtrees in parallel.
  • Breaking Change Removed the deprecated constructor of the VersionedLayerClient class.
  • Added the prefetch status callback. You can use it to receive the following prefetch progress information: the number of tiles prefetched, the total number of tiles requested, and total bytes transferred.
  • Added an experimental option to the prefetch API that you can use to prefetch a list of tiles as aggregated.

olp-cpp-sdk-dataservice-write

  • Breaking Change Removed the deprecated CancelAll methods from dataservice::write::VersionedLayerClient, dataservice::write::VolatileLayerClient, and dataservice::write::IndexLayerClient
  • Breaking Change Removed the deprecated CreateDefaultCache method from StreamLayerClient.h.
  • Work In Progress Enhanced olp::dataservice::write::VersionedLayerClient. The StartBatch and CompleteBatch methods now use olp::thread::TaskScheduler instead of network threads for asynchronous operations.
  • Fixed the duplicate requests used to configure the service in StreamLayerClient.
  • Fixed the upload issue in the stream layer that occurred when the layer compression was enabled on the platform at the same time as the ingest service was used.

v1.7.0 (06/16/2020)

Common

  • Changed the product name from HERE OLP SDK for C++ to HERE Data SDK for C++.
  • Fixed formatting to be compliant with the coding style.
  • Fixed the issue with olp::client::TaskContext. Now, it does not trigger cancellation after a successful operation.
  • Added the default_cache_expiration to olp::client::OlpClientSettings. Now, you can control how long the downloaded data is considered valid. Once the data is expired, you cannot retrieve it, and it is gradually removed from the cache when new data is added.
  • Added the OLP_SDK_DISABLE_DEBUG_LOGGING CMake option. When enabled, the SDK does not print any TRACE or DEBUG level log messages.
  • Added the compression setting to olp::cache::CacheSettings. You can now pass the flag to the underlying database engine to enable or disable the data compression.
  • Added the Compact API to olp::cache::DefaultCache. It is used to optimize the underlying mutable cache storage. Compaction also starts automatically once the database size reaches the maximum in a separate thread.
  • Changed the olp::cache::DefaultCache read operation. As a result, the number of memory allocation decreased, and performance increased.
  • Added support for the HTTP OPTIONS request in olp::http::Network.
  • The LRU eviction now evicts expired elements first. The eviction time decreased.
  • Removed the retry code from olp::http::NetworkCurl. Now, retries are performed by olp::client::OlpClient.
  • Added a prewarm helper method to olp::client::OlpClientSettingsFactory. This method can be used to perform DNS prefetch and TLS preconnect for certain URLs that are widely used by the clients. For example, accounts and lookup.
  • Enabled certificate validation in olp::http::NetworkCurl.

olp-cpp-sdk-authentication

  • The olp::authentication::TokenProvider class now handles the concurrent by blocking all requesters until the already triggered request completes. It verifies that only one token is requested at the same time.
  • The IntrospectApp and Authorize APIs now use ExponentialBackdownStrategy internally in case of a 5xx HTTP status code.
  • olp::authentication::AuthenticationError class is deprecated and will be replaced by olp::client::ApiError. It will be removed by 12.2020.
  • Switched the SignInClient method in the olp::authentication::AuthenticationClient functionality to TaskContext.

  • Changed the olp::authentication::ActionResult class. Permissions are now represented by the olp::authentication::Permission class.
  • The use_system_time flag in olp::authentication::Settings is now enabled by default. Now, system time is used for token requests by default.

olp-cpp-sdk-dataservice-read

  • The module now resolves all service APIs for a specific HRN in a single request.
  • Reduced the number of logs produced by the component.
  • Merged the same concurrent Lookup API requests into a single HTTP request.

  • Work In Progress Added a new ListVersions API to olp::dataservice::read::CatalogClient. You can use it to get information on catalog versions.
  • Work In Progress Added a new GetAggregatedData API to olp::dataservice::read::VersionedLayerClient. You can use it to retrieve tile data (if it exists) or the nearest parent tile data. Use this API for tile-tree structures where children tile data is aggregated and stored in parent tiles.

v1.6.0 (05/01/2020)

Common

  • Added the LRU functionality to the mutable disk cache. LRU is enabled by default. You can disable it using eviction_policy in CacheSettings.

v1.5.0 (07/04/2020)

Common

  • Moved the DefaultCache implementation to pimpl.
  • Fixed various compiler warnings.
  • CMake now uses the official Boost Github repository instead of downloading and unpacking the archive.
  • Method OlpClientSettingsFactory::CreateDefaultCache now returns nullptr if it failes to open one of the user-defined disk caches.
  • Work In Progress Added API to retrieve network statistics. It is not fully implemented yet, and users should not use it.

olp-cpp-sdk-authentication

  • Added a new use_system_time flag to olp::authentication::AuthenticationSettings. You can use it to tell the authentication module to work with system time instead of server time when retrieving tokens.

olp-cpp-sdk-dataservice-read

  • Added a stream layer read example. For more information, see our documentation.
  • Added the RemoveFromCache method to VolatileLayerClient. Now, you can remove specific partitions or tiles from the mutable cache.

  • Various improvements in olp::http::NetworkCurl implementation. Some legacy features were removed.
  • Added the SetDefaultHeaders method to olp::http::Network. Now, you can set default HTTP headers for each request made by Network. User agents set with default headers and user agents passed with network requests are concatenated into one header.
  • Reduced compiler warnings about deprecated methods and classes.

olp-cpp-sdk-authentication

  • Removed the deprecated AuthenticationClient::SignInClient method.

olp-cpp-sdk-dataservice-read

  • Added the RemoveFromCache method to VersionedLayerClient. Now, you can remove specific partitions or tiles from the mutable cache.
  • VersionedLayerClient now triggers an error when the request is passed with FetchOption::CacheWithUpdate. It makes no sense to update data when it is available in a cache for VersionedLayerClient since the version is locked.
  • Now, when you pass a request to VersionedLayerClient or VolatileLayerClient with FetchOption::OnlineOnly, data is not stored in a cache. It is designed for a use case when you are not interested in storing data in a cache.

olp-cpp-sdk-dataservice-write

  • Deprecated the olp::dataservice::write::StreamLayerClient::CreateDefaultCache method. It will be removed by 06.2020.

v1.3.0 (04/03/2020)

Common

  • Response headers are now stored in olp::client::HttpResponse. olp::client::OlpClient::CallApi() collects and adds headers to the response.
  • X-Correlation-ID is now extracted from the HTTP response headers and used for subsequent requests in olp::dataservice::read::StreamLayerClient.
  • Added a new backdown strategy to olp::client::RetrySettings. The default implementation is olp::client::ExponentialBackdownStrategy that restricts the maximum wait time during failed retries of network requests in the olp::network::client::OlpClient class (both synchronous and asynchronous versions). The accumulated wait time during retries should not be longer than the RetrySettings.timeout property.
  • Added curl_global_init() and curl_global_cleanup() to the olp::http::NetworkCurl class (Linux default implementation). For more information, see the olp::client::OlpClientSettingsFactory::CreateDefaultNetworkRequestHandler() function.
  • Fixed MSVC, Clang, and GCC warnings. Now, when you build with -Wall -Wextra, you should not face any hidden warnings, as the codebase is protected by a pre-release verification job.
  • Fixed the possible thread concurrency problem in the olp::client::OlpClient class that resulted in a crash in some situations.
  • Reduced data copy in the JSON serializers to increase performance.

olp-cpp-sdk-authentication

  • Added the olp::authentication::AuthenticationClient::IntrospectApp() method that you can use to retrieve information about the application associated with a particular access token.
  • Added a new olp::authentication::AuthenticationClient constructor using olp::authentication::AuthenticationSettings to setup network and task scheduler. It is a part of an ongoing authentication refactoring. Switch to this constructor instead of using the individual setters.

olp-cpp-sdk-dataservice-read

  • olp::dataservice::read::PartitionsRequest now supports a list of partition IDs. This way, when you use olp::dataservice::read::VersionedLayerClient and olp::dataservice::read::VolatileLayerClient, you can also request certain partitions instead of the entire layer metadata.
  • Added the Seek method to olp::dataservice::read::StreamLayerClient. This method can be used to start reading messages from a stream layer at any given position.
  • Added the Poll method to olp::dataservice::read::StreamLayerClient. This method reads messages from a stream layer and commits successfully consumed messages before handing them over to you.
  • Added the olp::dataservice::read::TileRequest class and corresponding GetData overload to olp::dataservice::read::VersionedLayerClient. Now, you can get data using a tile key. Internally, the metadata retrieval is optimized by using a quadtree request and saves bandwidth on subsequent GetData calls.
  • Added additional fields to the olp::dataservice::read::PartitionsRequest class. Now, you can access the following additional metadata fields: data size, compressed data size, checksum, and CRC.
  • Deprecated the WithVersion and the GetVersion methods in the olp::dataservice::read::DataRequest, olp::dataservice::read::PartitionsRequest and olp::dataservice::read::PrefetchTilesRequest classes. olp::dataservice::read::VersionedLayerClient now locks the catalog version either to the value provided on the constructor or by requesting the latest catalog version from the backend. This ensures that consistent data is provided for the instance lifecycle.
  • Fixed cache keys by appending 'partition' and 'partitions' to key values in olp::dataservice::read::VolatileLayerClient.
  • Fixed the infinite loop in the olp::dataservice::read::VersionedLayerClient::PrefetchTiles() method when min/max levels are not specified.

  • Fixed a possible data race in the olp::client::Condition class.
  • Added the MoveResult method to the olp::client::ApiResponse class. The method returns an rvalue reference to the result.
  • CMake now requires RapidJSON v1.1.0.
  • Various CMake cleanups.
  • Improved error handling in Android HttpClient.
  • Fixed the linking error when SDK was statically linked inside a shared library with CMAKE_POSITION_INDEPENDENT_CODE=ON.
  • The retry policy now handles server errors automatically.

olp-cpp-sdk-authentication

  • Deprecated the olp::authentication::TokenRequest class. It will be removed by 04.2020.
  • Deprecated various methods in olp::authentication::AuthenticationClient.
  • Authentication now gets the current timestamp from the platform and uses it to request the OAuth2 token that prevents replay attacks. As a fallback, the system time is used.

olp-cpp-sdk-dataservice-read

  • The olp::dataservice::read::QueryApi, olp::dataservice::read::MetadataApi, olp::dataservice::read::LookupApi, and olp::dataservice::read::BlobApi classes are now blocking and use the new synchronous CallApi method in OlpClient.
  • The GetData method of the versioned and volatile layer now triggers the olp::client::ErrorCode::PreconditionFailed error if both a partition ID and data handle are passed in the data request.
  • Work-in-progress: Added reading support for streamed data using the new olp::dataservice::read::StreamLayerClient. Currently, you can only subscribe, unsubscribe, and get data from a stream layer message.

olp-cpp-sdk-dataservice-write
