locust

• List Python 3.9 as supported in the package/on PyPi
• Fix XSS vulnerability in the web UI (sounds important but really isn't, as Locust UI is not meant to be exposed to outside users)

(side note: I have also fixed the docker build process, so any tagged commit will push to locustio/locust:latest, this was broken in the past)

• Bump minimum required gevent version to 20.9.0 (latest), as all the previous ones had sneaky binary incompatibilities with the latest version of greenlet ("RuntimeWarning: greenlet.greenlet size changed, may indicate binary incompatibility. Expected 144 from C header, got 152 from PyObject")

• Breaking change: Remove step-load feature (now that we have LoadTestShape it is no longer needed)
• More type hints to enable better code completion and linting of locustfiles
• Lots of documentation updates

Bug fixes:

• LoadTestShape.get_run_time is not relative to start of test https://github.com/locustio/locust/issues/1557
• Refactor and fix delayed user stopping in combination with on_stop https://github.com/locustio/locust/pull/1560
• runner.quit gets blocked by slow on stop https://github.com/locustio/locust/issues/1552
• Remove legacy code that was only needed for py2
• Lots more (https://github.com/locustio/locust/blob/master/CHANGELOG.md)

• Various linting fixes that should have no functional impact
• Bug fix (TypeError: code() takes at least 14 arguments (13 given) (Werkzeug version issue) https://github.com/locustio/locust/issues/1545)
• Bug fix (Locust stuck in "Shape worker starting" when restarting a test from the webUI https://github.com/locustio/locust/issues/1540)

• Bug fix (LoadTestShape in headless mode https://github.com/locustio/locust/pull/1539)

• Bug fix (StatsEntry.use_response_times_cache must be set to True, https://github.com/locustio/locust/issues/1531)

• Rename hatch rate to spawn rate (the –hatch-rate parameter is only deprecated, but the hatch_complete event has been renamed spawning_complete)
• Ability to generate any custom load shape with LoadTestShape class
• Allow ramping down of users
• Ability to use save custom percentiles
• Improve command line stats output
• Bug fixes (excessive precision of metrics in losust csv stats, negative response time when system clock has changed, issue with non-string failure messages, some typos etc)
• Documentation improvements

• Fix for run not ending if there is an exception in a test_stop listener
• FastHttpUser: Handle stream ended at an unexpected time and UnicodeDecodeError. Show bad/error status codes on failures page.
• Improve logging when locust master port is busy

• The official Docker image is now based on the python:3.8 image instead of python:3.8-alpine. This should
  make it easier to install other python packages when extending the locust docker image. #1435
• Allow Users to stop the runner by calling self.environment.runner.quit() (without deadlocking sometimes) #1448
• Cut to only 5% free space on the top of the graphs #1443
• Use csv module to generate csv data (solves issues with sample names that need escaping in csv) #1428
• Various documentation improvements

• Ability to control the exit code of the Locust process by setting environment.process_exit_code

0.14.3 version was missing wheel build

First Python 3 only version.

0.14.2 will give an error if installed on py2 (this was supposed to happen in 0.14.0, but post install steps dont work for wheels based packages, so I had to release a source-only package)

0.14.3 (and onwards) are pure py3 versions and will not be downloaded by pip2.

• Drop Python 2 and Python 3.5 support! #1120
• Continuously measure CPU usage and emit a warning if we get a five second average above 90% #1161
• Show CPU usage of slave nodes in the Web UI
• Fixed issue: when running Locust distributed and new slave nodes connected during the hatching/ramp-up
  phase https://github.com/locustio/locust/issues/1168
• Fixed issue: FastHttpLocust times out when HttpLocust does not #1246
