v0.17.0 checklist

[hyangah]

New Features

• Delve's function call feature is now accessible. To use this feature,
  explicitly specify the call command. E.g. call myAwesomeFunc().
  (Issue 100)
• The extension checks the go official site and notifies of
  newly available Go versions. This feature is available only if
  go.useGoProxyToCheckForToolUpdates is set true.
  (Issue 483)
• The new go.coverMode setting allows to use different coverage modes
  (atomic, count, set (default)). We are still looking for better data
  visualization for count coverage data; feedback and contribution is welcome!
  (Issue 256,

TODO: Rerender when the new settings are updated

Enhancement

• Expands '~' in the cwd attribute of the launch configuration.
  (Issue 116)
• Debug config's showGlobalVariables is disabled by default, and
  this change improves speed. You can still inspect the global
  variables by registering them in the WATCH section, or by
  configuring showGlobalVariables in launch.json.
  (Issue 138)
• gofumpt, gofumports is added to recognized formatters list.
  (Issue 587)
• Automatically restarts the language server if go.toolsEnvVars configuration is changed.
  (CL 254370)
• Reports go env failures.
  (Issue 555)

Fixes

• Fixed to use absolute file paths in error messages appearing in the DEBUG OUTPUT.
  This allows VS Code to locate the correct files.
  (Issue 456)
• Fixed handling of absolute file paths in coverage profile, on windows.
  (Issue 553)
• Changed to pass GOROOT when invoking the gopkgs tool so gopkgs
  continues to work with different go versions without being recompiled.
  (CL 254137)
• Fixed to provide explicit directory for running go list and go version.
  (Issue 610,
  CL 253600,
  253602)
• Fixed to trigger extension activation when commands for diagnostics,
  such as Go: Locate Configured Go Tools are invoked.
  (Issue 457)
• Fixed to prepend GOROOT/bin to integrated terminal's PATH
  environment variable when go.goroot is set on OS X.
  (Issue 544)
• Fixed to correctly apply environment variables setting read from envFile
  in the launch configuration. We reworked how the environment variables
  configuration is processed during this cycle. Now the extension processes
  the envFile attribute instead of asking the debug adapter process to
  read the specified envFile.
  (Issue 452)
• Disabled go.installDependenciesWhenBuilding by default. When this is
  enabled, the extension runs go commands with -i, which is no longer
  recommended with recent versions of Go.
  (Issue 568)

Documentation

• Added new documentation about
  switching go versions,
  and settings for standard library development.
• Improved debugging instruction and contribution guide. Enhanced automated settings documentation generation.

Code Health

• Removed the obsolete string-type coverageDecorator support.
  (Issue 519)
• When gopls integration tests fail, tests print the observed gopls traces
  to help debugging.

Experimental Features

• We plan to delegate computation of various run test CodeLenses to gopls.
  The feature can be enabled with the following setting:

"go.useLanguageServer": true,
"gopls": {
	"codelens": { "test": true }
}
