[Unreleased]

Changed

  • core now depends on pretty_assertions crate
  • ChainHeader::sources() is now ChainHeader::provenances()
  • Headers from other agents are stored in the EAV
  • hdk::get_entry_results supports return of ChainHeaders for all agents who have committed the same entry
  • Rename the term Container and all references to it to Conductor
  • The holochain_container executable has been renamed to simply holochain
  • cmd crate (which implements the hc command line tool) renamed to cli
  • Encoded values in ribosome function's input/output are u64 (up from u32)
  • Capabilities now separated from function declarations in define_zome! and calling zome functions no longer uses capability name parameter #791
  • Updated dependencies:
    • Rust nightly to 2019-01-24
    • futures to 0.3.0-alpha.12
  • Adjusted so that all chain headers are sent in the validation package, not just those for public entry types

Added

  • Adds an environment variable HC_SIMPLE_LOGGER_MUTE for use in testing which silences logging output so CI logs won't be too big.

  • Added Zome API function hdk::sleep(std::time::Duration) which works the same as std::thread::sleep.

  • All structs/values to all HDK functions must implement Into<JsonString> and TryFrom<JsonString> (derive DefaultJson to do this automatically)

  • HDK globals AGENT_ADDRESS, AGENT_ID_STR, DNA_NAME and DNA_ADDRESS are now set to real, correct values.

  • hc run now looks for the --interface flag or HC_INTERFACE env var if you want to specify the http interface [#846]((holochain#779)

  • Scenario API added to enable deterministic scenario tests for zome functions. See the NodeJS Conductor README for details.

  • hdk::query_result API supports return of ChainHeader and/or Entry data for the matched EntryType(s)

  • Admin RPC functions added to container interface. Any (websocket) container interface that is configured with admin = true now can call the following functions to remotely change any aspect of the container config (intended to be used in an upcoming container admin UI):

    • admin/dna/install_from_file (install a DNA from a local file)
    • admin/dna/uninstall
    • admin/dna/list
    • admin/instance/add
    • admin/instance/remove
    • admin/instance/start
    • admin/instance/stop
    • admin/instance/list (list of all instances in config)
    • admin/instance/running (list of currently running instances)
    • admin/interface/add (starts the interface)
    • admin/interface/remove (stops the interface)
    • admin/interface/add_instance (restarts the interface to get change in effect)
    • admin/interface/remove_instance (restarts the interface to get change in effect)
    • admin/interface/list
    • admin/agent/add
    • admin/agent/remove
    • admin/agent/list
    • admin/bridge/add
    • admin/bridge/remove
    • admin/bridge/list

  • Hosting of static files over HTTP to allow for container hosted web UIs

  • UI bundle admin RPC functions Adds a further set of functions to the container RPC for managing static UI bundles and HTTP interfaces to these. This adds the following RPC endpoints:

    • admin/ui/install
    • admin/ui/uninstall
    • admin/ui/list
    • admin/ui_interface/add
    • admin/ui_interface/remove
    • admin/ui_interface/list
    • admin/ui_interface/start
    • admin/ui_interface/stop

    See rustdoc of conductor_api::interface::ConductorApiBuilder for a full description of these functions.

  • Conductor can serve static directories called ui_bundles over HTTP that can be configured in the container config toml file. This HTTP server also implements a virtual json file at "/_dna_connections.json" that returns the DNA interface (if any) the UI is configured to connect to. Hc-web-client will use this to automatically connect to the correct DNA interface on page load.
