v0.11.2

• introduce telnet Controller allowing real-time control of load test, optionally disable with --no-telnet, supports the following commands:
  o help (and ?) display help
  o exit (and quit) exit the telnet Controller
  o shutdown shuts down the running load test (and exits the controller)
  o host (and hosts) HOST sets host to load test against, ie http://localhost/
  o users (and user) INT sets number of simulated users
  o hatchrate (and hatch_rate) FLOAT sets per-second rate users hatch
  o runtime (and run_time) TIME sets how long the load test should run
  o config displays the current load test configuration
  o config-json displays the current load test configuration in json format
  o metrics (and stats) displays metrics for the current load test
  o metrics-json (and stats-json) displays metrics for the current load test in json format
• telnet Controller bind host defaults to 0.0.0.0, can be configured with --telnet-host
• telnet Controller bind port defaults to 5116, can be configured with --telnet-port
• telnet Controller defaults can be changed:
  o default to not enabling telnet Controller: GooseDefault::NoTelnet (bool)
  o default host to bind telnet Controller to: GooseDefault::TelnetHost (&str)
  o default port to bind telnet Controller to: GooseDefault::TelnetPort (usize)
• introduce WebSocket Controller allowing real-time control of load test, optionally disable with --no-websocket, supports the same commands as the telnet Controller, except:
  o config and config-json both return the load test configuration in json format
  o metrics and metrics-json both return metrics for the current load test in json format
• WebSocket Controller bind host defaults to 0.0.0.0, can be configured with --websocket-host
• WebSocket Controller bind port defaults to 5117, can be configured with --websocket-port
• WebSocket Controller defaults can be changed:
  o default to not enabling WebSocket Controller: GooseDefault::NoWebSocket (bool)
  o default host to bind WebSocket Controller to: GooseDefault::WebSocketHost (&str)
  o default port to bind WebSocket Controller to: GooseDefault::WebSocketPort (usize)
• make it possible to start and stop a load test without completely restarting Goose
• introduce --no-autostart to disable automatically starting the load test, leaves Goose in an idle state waiting for Controller commands (optionally change the default with GooseDefault::NoAutoStart)
  o renamed stop Controller command to shutdown
  o added new start Controller command, telling idle Goose load test to start
  o added new stop Controller command, telling running Goose load test to stop and return to idle state
• code cleanup and logic consollidation to support Controller fixed a bug where metrics wouldn't display and the debug file, request file, and html report weren't written when load test was stopped while still launching users
• regularly sync metrics, using a timeout to avoid hanging the main loop
• properly reset metrics when load test is stopped and restarted
• properly flush debug file, request file, and html report when stopping load test with Controller
• properly (re)create debug file, request file, and html report when starting load test with Controller
• if metrics are enabled, display when controller stops load test
• de-duplicate code with traits, gaining compile-time validation that both Controllers are properly handling all defined commands
• add async_trait dependency as stable Rust doesn't otherwise support async traits
• allow starting Goose without specifying a host if --no-autostart is enabled, requiring instead that the host be configured via a Controller before starting a load test
• add test for telnet and WebSocket Controllers

v0.11.1

0.11.1 May 16, 2021

• update rand dependency to 0.8 branch, update gen_range method call
• update dependencies: itertools to 0.10, simplelog to 0.10, url to 2
• update nng dependency for optional gaggle feature
• simplify examples/umami regex when parsing form
• allow configuration of algorithm for allocating GooseTasks the same as GooseTaskSets; GooseTaskSetScheduler becomes more generically GooseScheduler
• specify (and detect) minimum rustc requirement of 1.49.0, due to flume dependency which in turn depends on spinning_top which uses hint::spin_loop which stabilized in rustc version 1.49.0
• standardize links in documentation; general documentation cleanups

v0.11.0

0.11.0 April 9, 2021

• capture errors and count frequency for each, including summary in metrics report; optionally disable with --no-error-summary
• clippy cleanups (prepare for Rust 2021 https://blog.rust-lang.org/inside-rust/2021/03/04/planning-rust-2021.html):
  • API change: all GooseMethods renamed to enforce Rust naming conventions in regards to case, for example GooseMethod::GET becomes GooseMethod::Get
  • use vec![] macro to avoid unnecessarily pushing data into mutable vectors
  • call format! macro directly for improved readability
  • remove unnecessary panic!

v0.10.9

0.10.9 March 23, 2021

• avoid unnecessary work on Manager when starting a Gaggle
• respect --hatch-rate when starting a Gaggle
• update httpmock for running tests
• remove unnecessary Result() types where no error was possible

v0.10.8

• upgrade to tokio 1.x, and switch to flume for all multi-producer, multi-consumer channels
• introduce --report-file (and GooseDefault::ReportFile) to optionally generate an HTML report when the load test completes
• make examples/umami more generic for easier load testing of any Drupal 9 version of the demo install profile

v0.10.7

0.10.7 Nov 16, 2020

• account for time spent doing things other than sleeping, maintaining more consistency when displaying statistics and shutting down
• start each debug log file with a line feed in case the page is too big for the buffer; increase the debug logger buffer size from 8K to 8M.
• introduce --no-debug-body flag to optionally prevent debug log from including the response body
• rename the metrics file to requests file to better reflect what it is
  o --metrics-file becomes --requests-file
  o --metrics-format becomes --requests-format

  o GooseTaskSetScheduler::RoundRobin allocates 1 of each available GooseTaskSet at a time (new default)
  o GooseTaskSetScheduler::Serial allocates all of each available GooseTaskSet in the order they are defined
  o GooseTaskSetScheduler::Random allocates 1 random GooseTaskSet from all available
