3.3.0-rc.4 (2022-06-27)

  • service director fix: ProcessingEnd was not called in some case, leading to RUNNING process with no jobs (which should never happen).

  • service director: log warnings in the process on timeout errors

  • envelope-storage-ng: fix handling an initial ‘null’ fragment

3.3.0-rc.3 (2022-06-21)

  • service ‘metrics’

    • fix log storage size gauge

3.3.0-rc.2 (2022-05-12)

    • Add a metrics gathering EnvelopeStorage layer. It is automatically enabled when xbusd metrics are ‘on’.

    • Add a new EnvelopeStorage implementation with better performances: EnvelopeStorageNG. Can be enabled with --storage.envelope.impl "sql-ng".

    • Add a fallback mechanism for EnvelopeStorage, to make envelope storage transition smoothless. Can be enabled with --storage.envelope.fallback.

    • Add a cached EnvelopeStorage layer that works on top of a persistent implementation. Can be enabled with --storage.envelope.cache.enabled. The cache size is 1Gio max, which can be changed with --storage.envelope.cache.max-size.

  • Table process_state: - Add field pm_level varchar(255) - Add field pm_status varchar(255) - Add field pm_comment varchar(255)

  • A backwards incompatible change has been introduced in the configuration: database becomes database.dsn, the cli flag database becomes database-dns. Refer to the sample file etc/xbusd_sample.yaml.

3.0.0-beta.7 (2017-03-09)

  • Add support for fragmented envelopes, which implies a lot of code cleaning and a few refactoring.

  • Add a route cache

  • Reduce broker/emission coupling

  • Now requires Postgresql >= 9.5

  • New Table: route

  • New Table: route_target

3.0.0-beta.6 (2017-02-03)

  • [doc] Update Quickstart to match latest go-xbus demo.relay settings

  • [auth] Remove debug log when a client is authenticated

  • Switch to go-xbus 3.0.0-beta.6

  • Fix a host / port parsing issue that was preventing the nats-host setting from being set to 0.0.0.0.

3.0.0-beta.5 (2017-01-26)

  • Switch to go-xbus 3.0.0-beta.5

  • Fix: graph validation error message for invalid edges were wrong (‘origin’ was switched with ‘destination’.

  • Doc: Add a fully fonctionnal graph to the Quickstart section, making it a complete and running example of a bus.

  • New: Graph nodes how have a actors attribute, which references actors by name or id. The actorids attribute is deprecated.

  • Fix: In case no graph matches a new envelope, a ack error is returned to the emitter.

  • New: Table graph_node: add field actors varchar(255)

  • xbusd: Allow custom hostdefs for server CA

  • xbus-client: Embed demo actors from go-xbus/demo

3.0.0-beta.4 (2017-01-20)

  • Build releases binaries from the right changeset.

  • Extract reusable parts of this program to go-xbus.

  • Switch to go-xbus 3.0.0-beta.4

3.0.0-beta.3 (2017-01-13)

  • API Break: Add the “ActorProcessingEnd” entry point. It must be called by consumers to signal processing success or failure, and by other actors for processing errors. It adds support for long-running processing by consumers without hitting transfert timeout.

  • API Beak: Rename ActorType to ActorKind, and all ‘Type’ fields of type ActorType to ‘Kind’.

  • API Addition: Add a logging API for actors.

  • Provides a SQL migration script, that does: - actor table: Drop unique index (name / type). - actor table: Add a unique index (name). - actor table: Rename type to kind. - emission table: event_positions type changed to TEXT (was VARCHAR(255)) - New log_entry table that stores log messages.

  • Gnatsd: switch to upstream version (which merged our TLS auth related patch)

  • Better test coverage

  • More graph examples in the graph doc

  • Graph validation: Check for invalid or duplicate node ids

  • xbus-client: Better behavior when configuration file is missing

  • make xbus-client/cmd extendable

  • client: Add apis to easily start a group of actors from a configuration file

3.0.0-beta.2 (2016-12-22)

  • Graph validation. When pushing a graph, a list of validation errors (if any) will be returned and displayed. A non-valid graph cannot be published, preventing many common mistakes that would be otherwise hard to detect.

  • Optionnally capture SQL logs (see xbusd serve options –debug-sql-queries and –debug-sql-bindings)

  • Embed detailed version information in the binaries (try –version and –full-version flags on the binaries)

  • Upgrade gnatsd embedded version

  • Build static binaries

  • Embed documentation in the distribution package

  • Documentation fixes

  • A few logging level changes

3.0.0-beta.1 (2016-12-12)
