GoLand 2022.1 Help

The IDE does not respond

When GoLand does not respond, consider creating a thread dump file. A dump file must be created at the moment when the IDE does not respond and include the thread stack. Recording several thread dumps with 1-2 seconds interval might be useful for the problem analysis.

After you have created a dump thread file, archive it, and upload it to share with the JetBrains support team. Read upload instructions in the Upload snapshots section.

You can create thread dumps by using the following options:

Using jstack

The jstack command-line utility prints Java stack traces of Java threads. The utility is provided with the JDK installation and can be found in the JAVA_HOME\bin directory.

Ensure that the utility has the same JDK version as GoLand. For example, the 64-bit JDK distribution of the utility will not work for the IDE that runs under the 32-bit JDK distribution. To check the JDK version, press Ctrl+Shift+A, type About, and press Enter.

Check the JDK version

Create thread dumps by using jstack

  1. Open the command prompt.

  2. List Java processes that run on your system with their command-line options. Type the following command and press Enter.

    jps -mv
  3. Run jstack with the IDE process identifier (PID). Type the following command and press Enter.

    jstack -l <PID> > dump.txt

    This command prints the thread dump into a file.

    Using jstack

Automatic thread dumps

GoLand runs a thread that detects when UI does not respond for a certain time and writes automatic thread dumps into the log directory. To find the log directory, click Help | Show Log in <file_browser>. You will find several folders with the name like threadDumps-freeze-20201215-083644-GO-211.3076. Zip these folders and attach them to your ticket.

Thread dump from the console

Depending on your operating system, you can create a thread dump without the jstack utility.

macOS

  1. Navigate to the goland file in IDE_HOME/GoLand.app/Contents/MacOS/.

    Depending on how you installed your IDE, IDE_HOME might be /Applications/ (standalone installation) or ~/Library/Application Support/JetBrains/Toolbox/apps/goland/ch-2/203.5981.102/ (Toolbox installation).

  2. Right-click the goland file and select Open with | Terminal.

  3. Press ^\. The terminal will print a thread dump. To complete the process, press ^C.

Microsoft Windows

  1. Open the command prompt.

  2. By using the cd command, navigate to the goland.bat file in the bin directory inside your IDE installation directory.

    Depending on how you installed your IDE, the installation directory might be C:\Program Files\JetBrains\GoLand 2020.3\ (standalone installation) or C:\Users\User\AppData\Local\JetBrains\Toolbox\apps\goland\ch-1\211.3208\ (Toolbox installation).

  3. Run the goland.bat file.

    goland.bat > output.txt
  4. Press Ctrl+Break. The terminal will print a thread dump. To complete the process, press Ctrl+C.

Unix

  1. Run the goland.sh file in the bin directory inside your IDE installation directory.

    Depending on how you installed your IDE, the installation directory might be any directory that you have chosen (standalone installation) or ~/.local/share/JetBrains/Toolbox/apps/GoLand/ch-0/211.3208 (Toolbox installation).

  2. By using a process manager (for example, ps, htop, jps), get the process ID (PID).

  3. Run the following command or send the SIGQUIT signal to the process. A thread dump will be printed in the terminal window.
