Noteworthy Changes for 3.0.0 (TBD)

Backwards incompatible changes

  • Deployment Admin bundle has been removed and is no longer supported.
  • The libs dependency_manager_static, shell_dm and dependency_manager_cxx_static are removed. These libraries are not needed anymore. The dependency manager is an integral part of the framework lib and the dm command is part of the standard shell commands.
  • Shell v2 api is removed and no longer supported.
  • Logging v2 api is removed and no longer supported.
  • Bonjour Shell bundle is removed and no longer supported.
  • pubsub_serializer.h is removed and no longer supported. Use pubsub_message_serialization_service.h instead.
  • C++11 support for dm is removed. C++14 is now the minimum required version.
  • C++17 string_view support is removed from the utils and framework lib.
  • Apache Celix CMake container & bundle functions without a celix_ prefix or infix are removed.
  • Apache Celix CMake support for creating docker images and creating runtimes dirs is removed.
  • Support and usage of "service.lang" service property is removed.
  • Rename of CELIX_FRAMEWORK_FRAMEWORK_CACHE_DIR config property to CELIX_FRAMEWORK_CACHE_DIR.
  • Rename of OSGI_FRAMEWORK_FRAMEWORK_UUID config property to CELIX_FRAMEWORK_UUID.
  • Support for OSGI_FRAMEWORK_* config properties are dropped. Use CELIX_FRAMEWORK_* instead. This includes: Note this includes the OSGI_FRAMEWORK_FRAMEWORK_STORAGE ("org.osgi.framework.storage") config property, which has been replaced with the CELIX_FRAMEWORK_CACHE_DIR config property.
    • The OSGI_FRAMEWORK_OBJECTCLASS ("objectClass") service property, replacement is CELIX_FRAMEWORK_SERVICE_NAME.
    • The OSGI_FRAMEWORK_FRAMEWORK_STORAGE ("org.osgi.framework.storage") config property, replacement is CELIX_FRAMEWORK_CACHE_DIR.
    • The CELIX_FRAMEWORK_FRAMEWORK_STORAGE_CLEAN_NAME ("org.osgi.framework.storage.clean") config property, replacement is CELIX_FRAMEWORK_CLEAN_CACHE_DIR_ON_CREATE.
    • The OSGI_FRAMEWORK_UUID ("org.osgi.framework.uuid") config property, replacement is CELIX_FRAMEWORK_UUID.
  • Removed support for bundle activator symbols without a celix_ prefix.
  • Removed service property constant CELIX_FRAMEWORK_SERVICE_PID.
  • Support and usage of "service.lang" service property is removed.
  • pubsub_serializer.h is removed and no longer supported. Use pubsub_message_serialization_service.h instead.
  • C Properties are no longer a direct typedef of hashmap.
  • celix_string/long_hashmap put functions now return a celix_status_t instead of bool (value replaced). THe celix_status_t is used to indicate an ENOMEM error.
  • Embedded bundles are no longer supported.
  • properties.h is removed and no longer supported. Use celix_properties.h instead.
  • linked_list.h is removed and no longer supported. Use celix_array_list.h instead.
  • ip_utils.h is removed and no longer supported.
  • array_list.h is removed and no longer supported. Use celix_array_list.h instead.
  • the celix_arrayList_add function no longer accepts a NULL value.
  • version.h and version_range.h are removed and no longer supported. Use celix_version.h and celix_version_range.h instead.
  • The signature of celix_bundleContext_trackServices has changed. The signature is now simpler to better support the use-case of using a service tracker with the celix_bundleContext_useTrackedService* functions. The celix_bundleContext_trackServicesWithOptions is still available for more advanced use-cases.
  • Function celix_bundle_destroyServiceTrackerList is removed. The returned array list from celix_bundle_listServiceTrackers is now configured to destroy the service trackers info entries.
  • It is no longer possible to use the celix_bundleContext_useService* functions or celix::BundleContxt::useService* methods on the Celix event thread. The calls will now immediately return and log an error if called on the Celix event thread.
  • Apache Celix filter now uses the underlying properties value types for matching. This means that it is more important to add service properties with the correct type.
  • Celix C++ Exception are now defined in the celix/exceptions.h header file. The celix/Exception.h and celix/IOException.h are removed.
  • The seperator for CELIX_AUTO_START_0 .. CELIX_AUTO_START_6 and CELIX_AUTO_INSTALL is now a comma instead of a space.
  • The launcher now only has two public functions: celix_launcher_launchAndWait and celix_launcher_triggerStop. The other functions are removed.
  • The manifest format has been changed to JSON, and the manifest attribute names have been changed. The old manifest format is no longer supported. The old manifest attribute names are also no longer defined in celix_constants.h.
