Changes

2.0.1

• Fix a race where run could return before the simulation post-hook had been called (regression in 2.0.0)

2.0.0

• Breaking: Java 21 or later is required
• Run virtual users and requests in virtual threads instead of core.async go blocks. Request functions that block (e.g. clj-http, JDBC) no longer need a tuned thread pool. In benchmarks throughput was 11x higher for blocking request functions, 3x higher for callback based request functions (e.g. http-kit) and the maximum throughput of the runner itself was ~10x higher
• Bump core.async to 1.9.865. The clojure.core.async.pool-size system property is not supported anymore. See README section Tuning parallelism
• Fix short summary reporter undercounting failed requests when a batch had both false and nil results
• Remove trombi.simulation/asynchronize and trombi.simulation/async-function-with-timeout, which were internal functions
• Bump dependencies (Clojure 1.12.6, Prismatic Schema 1.4.2)

1.0.2

• Validate simulation before starting the run. Previously an invalid simulation made run hang instead of throwing an error (#99)
• Fix file based raw reporter leaving raw.log empty when simulation produces fewer than 20000 results (#80)
• Fix progress reporter showing negative concurrency values in the end of the simulation (#89)

1.0.1

• Fix division by zero bug in experimental stats

1.0.0

• Project renamed to Trombi
• Gatling Highcharts and http-kit dependencies are not included by default
• Only short summary reporter is used when reporters config option is omitted
• Bump dependencies

0.18.0

• Fix a bug in concurrency weight between multiple scenarios
• Fix a race condition bug in force stop
• Fix a bug in reporter console output showing values too early
• Add global min, max and mean measurements to short summary

0.17.6

• Fix a bug in console progress tracker.
• Start runners in parallel to improve simulation results.
• Bump dependendencies & Clojure

0.17.5

• Add experimental support for tracking active thread count in test client

0.17.4

• Fix progress calculation. Progress should never exceed 1.0

0.17.3

• Add support for force stopping simulation from the progress tracker
• Add possibility to run simulation in background with new 'run-async` function in core

0.17.2

• Add support for latest version of Gatling Highcharts reports with percentiles
• Catch also AssertionError and categorise it as a step failure
• Bump dependencies

0.17.1

• Add support for stringified exceptions in reports

0.17.0

• Add support for simulations defined by rate (new requests/sec) rather than concurrency

0.16.1

• Add raw reporters
• Fix highcharts reporter simulation timestamp on report frontpage
• Update dependencies

0.16.0

• Add support for customizable progress tracker
• Replace deprecated clj-time with Java 8 time objects
• Upgrade Clojure from 1.10.1 to 1.10.3
• Update dependencies

0.15.1

• Fix: Verify that at least one user is running every scenario

0.15.0

• Use own implementation of timeout to avoid reusing same timeout. That was an issue with high concurrency
• Upgrade core.async

0.14.0

• Upgrade Clojure from 1.8.0 to 1.10.1
• Update dependencies

0.13.0

• Add support for dynamic scenarios
• Update dependencies.

0.12.0

• Internal refactoring. Possibility to add custom remote reporters and executors.
• Update dependencies. JDK9 support

0.11.0

• Add scenario hooks
• Update dependencies

0.10.2

• Fix weighted scenarios concurrency distribution algorithm

0.10.1

• Use Jenkins Gatling plugin compatible folder name for the results

0.10.0

• Support for concurrency distribution

0.9.3

• Bump dependencies

0.9.2

• Fix a NPE with running legacy simulation (pre 0.8)

0.9.1

• Move gatling-highcharts-reporter to own repository

0.9.0

• Add pre-hook and post-hook for simulation

0.8.6

• Add error (stacktrace) logging

0.8.5

• Add option for scenario specific context.

0.8.4

• Fix StackOverFlow error when running with large number of users (> 2500)

0.8.3

• Pass :context-before and :context-after to reporter.

0.8.2

• Add scenario option for allowing early termination.

0.8.1

• Add option for specifying your own custom reporter.

0.8.0

• Upgraded to Clojure 1.8.
• New format for specifying the simulation and options (with schema validation). Note! Backwards compatibility is kept for now.
• Support for sleeping before starting a request

0.7.x

• Buffer results to file system while simulation is running. This makes it possible to run clj-gatling for long period of time without running out of memory.

0.6.x

• Upgraded to Clojure 1.7.
• Changed format of request functions. Callback is the first parameter and user-id is not separate parameter anymore. You can get user-id from context via :user-id key.
