Environment Variables with spaces are truncated when written to properties file

    XMLWordPrintable

    Details

    • Steps to Reproduce:
      Hide

      set a CONNECT_ environment variable to a value that contains a space.  Run the docker image and inspect connect-distributed.properties.

       

      I have distilled the issue here:

      #!/usr/bin/env bash
      export CONNECT_VAR_WITH_SPACE="some text with spaces" 
      echo "old way"
      for VAR in `env` 
      do 
        env_var=`echo "$VAR" | gsed -r "s/(.*)=.*/\1/g"` 
        if [[ $env_var =~ ^CONNECT ]]; then 
          prop_name=`echo "$VAR" | gsed -r "s/^CONNECT_(.*)=.*/\1/g" | tr '[:upper:]' '[:lower:]' | tr _ .` 
          echo "$prop_name=${!env_var}" 
        fi 
      done
      echo "new way" 
      for VAR in `env` 
      do 
        env_var=`echo "$VAR" | gsed -r "s/(.*)=.*/\1/g"` 
        if [[ $env_var =~ ^CONNECT ]]; then 
          prop_name=`echo "$VAR" | gsed -r "s/^CONNECT_(.*)=.*/\1/g" | tr '[:upper:]' '[:lower:]' | tr _ .` 
          prop_value=`echo "$VAR" | gsed -r "s/^CONNECT_.*=(.*)/\1/g"` 
          echo "$prop_name=${prop_value}" 
        fi 
      done
      

      which outputs:

       

      $ ./test.sh
      old way
      var.with.space=some text with spaces
      new way
      var.with.space=some

      Description

      DBZ-3019 introduced a regression in the ENV to properties file routine in the docker-entrypoint.sh.

      After this PR, any CONNECT_ environment value has the value truncated at the first space before it is written to the properties value.  This is problematic for anyone using JAAS.
