• Added support for dynamic container ports - allows passing randomly generated port to the container and then exposing that same port, it may be easier to configure some containers that way than by port remapping. by @Caparow (#1097)
• Hotfixed JDK 1.8 compatbility broken in 0.10.11 (#1100)

Pull requests merged since 0.10.10:

• Enable docker tests on CI (#1101)

distage-framework-docker:

• Added support for custom docker container readiness checks by @Caparow (#1094)
• Bundled PostgresDocker container now uses a custom check that suceeds only once SQL protocol is truly available (postgres docker re-launches twice during normal bootup - first time to setup schema and users, making port check insufficient to assert readiness - postgres connection will fail if connected during the first boot-up) by @Caparow

Pull requests merged since 0.10.10:

distage-testkit:

• Smart merging of memoization environments by @Caparow (#1072)
  distage-testkit allows designating components as memoization roots, these 'memoized' components will then be instantiated just before all tests start and shared between them. In practice, because TestConfig allows overriding component implementations and changing dependency injection parameters, memoized components couldn't be safely shared between tests with different TestConfigs; to mitigate that, nearly any difference in TestConfig fields between tests would result in creation of a separate memoization environment that would reacquire global resources again. This split of memoization environments meant it was hard to ensure global sharing and easy to break it. e.g. by using TestConfig#moduleOverrides to override a component implementation within a suite.
  • New smart merging strategy solved this brittleness by changing the criteria for splitting into multiple environments. Instead of splitting by the input (TestConfig) in fear of potential changes to the output (the shared components sub-graph), we first compute the dependency injection plan for all TestConfigs and then compare the results - if the plans are equal we can safely conclude that the output object graphs will be equal as well and merge the memoization environments. In practice this means that now, inversely, nearly all changes to TestConfig will NOT cause global component sharing to break, unless they directly affect the memoization root components OR their dependencies.
• Added option to specify a fixed level of parallelism for tests, suites and memoization environments in TestConfig in addition to unlimited parallelism / sequential only execution. by @Caparow (#1064)
• New logs were added to enumerate the memoization environments and the suite classes included in them.

distage-framework-docker:

• Randomized port numbers are now passed into docker containers as environment variables of form export DISTAGE_PORT_TCP_8080=38553 where 8080 is the exposed port. by @Caparow (#1079)
• Added ElasticMQDocker for softwaremill/elasticmq as a usage example for port environment variables. by @Caparow (#1079)
• ContainerConfig#cmd was renamed ContainerConfig#entrypoint by @Caparow (#1079)
• Use default Docker.ClientConfig if docker config section is not found instead of failing (#1075)
• DockerContainerModule was renamed to DockerSupportModule (#1070)

distage-extension-config:

• Add makeConfigWithDefault, wireConfig, wireConfigWithDefault to ConfigModuleDef (#1075)

distage-core:

• GCMode was renamed to Roots (#1059)
• add DIKey.apply short-hand (write DIKey[T]/DIKey[T]("x") instead of DIKey.get[T]/DIKey.get[T].named("x")) (#1059)
