Proposed changes

  • Appium writes all log levels (dbug, info, WARN, erro) to stderr, not stdout
  • The onErrorMessage stderr handler was rejecting the startup promise on any unrecognized stderr data
  • OS pipes deliver data in arbitrary chunks, so dbugError: Appium Creating hash file directory:... could arrive as two chunks: dbug then Error: Appium Creating... making any prefix-based allowlist unreliable
  • The partial fix from appium server fails on warnings #14770 (allowing WARN through) did not cover other log levels

Types of changes

  • Polish (an improvement for an existing feature)
  • Bugfix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to not work as expected)
  • Documentation update (improvements to the project's docs)
  • Specification changes (updates to WebDriver command specifications)
  • Internal updates (everything related to internal scripts, governance documentation and CI files)

Checklist

  • I have read the CONTRIBUTING doc
  • I have added tests that prove my fix is effective or that my feature works
  • I have added the necessary documentation (if appropriate)
  • I have added proper type definitions for new commands (if appropriate)

Backport Request

//: # (The current main branch is the development branch for WebdriverIO v9. If your change should be released to the current major version of WebdriverIO (v8), please raise another PR with the same changes against the v8 branch.)

  • This change is solely for v9 and doesn't need to be back-ported
  • Back-ported PR at #XXXXX

@mccmrunal

I'm now simplifying this because I got issues with newer versions of Appium (Appium 3). I now also had issues with the appium-inspector which could be executed with npx start-appium-inspector --port=4725 --relaxed-security

Can you also check this again befor we merge it? Just making sure I'm not missing stuff

This doesn't seem like intentional behavior - could you please also create a bug ticket on the Appium repo?
(I would suggest reporting any other Appium-related issues in the repo as well)
