Bug fixes

• Extension host crashing with SIGPIPE error on machines that do not have the Go tools that the extension depends on instead of graceful error handling. Bug 1845
• Build fails on unix machines if user doesnt have entry in the /etc/passwd file. Bug 1850
• Avoid repeating gopath when the inferred gopath is the same as env gopath

Workarounds for upstream electron issue

Due to an upstream issue with newer version of electron that was shipped with VS Code 1.26.0 recently, some users might see an SIGPIPE error instead of graceful error handling of the absence of certain Go tools. This release attempts to work around this issue by trying to catch such cases earlier and prompting the user to install the missing tool.

Upstream Issue in VS Code: microsoft/vscode#56301
Upstream Issue in Electron: electron/electron#13254 and electron/electron#13679

Debugging improvements and bug fixes

Debugging improvements

• Zyck (@qzyse2017)

  • Introducing a new mode for debugging called auto. In this mode, the debugging sessions will run in test mode automatically if the current active file is a test file. Otherwise this defaults to the usual debug mode. Feature Request 1780

• Luis GG (@lggomez)

  • Errors from delve api calls are now shown in the debug console when "showLog": true is added to the debug configuration. PR 1815.

• Ramya Rao (@ramya-rao-a)

  • Fix bug when debugging a program that runs in a loop forever is not stopped when the stop button is clicked. Bug 1814
  • Fix bug when a previous failed debugging session due to compile errors results in failure of future sessions after fixing the compile error. Bug 1840
  • The environment variables in go.toolsEnvVars setting which gets used by all Go tools in this extension will now be passed to dlv as well during debugging sessions. With this change you dont need to repeat the variables in the debug configuration if you have already added it in the settings.

Others

• Ramya Rao (@ramya-rao-a)

  • The go.gopath command when run programatically by other extensions now returns the GOPATH as determined by this extension. Useful for other extensions that want to provide additional features but do not want to repeat the work done by this extension to determine the GOPATH.
