             Project: WildFly
          Issue Type: Bug
          Components: Scripts
    Affects Versions: 10.1.0.Final
         Environment: centOs
            Reporter: Nuno Godinho de Matos

             Fix For: 10.2.0.Final


Hi, I am currently migrating some windows batch scripts associated to an automated create domain/stanadlone process.

One of these scripts, consists on faclitating the user to invoke the jboss cli to run a cli file.
While on windows the script is natrually working.
On linux centOs, the script immediately broke with the error:

{panel}
[johnDoe at localhost bin]$ sh 01_invoke_cli_file_script.sh "file99.sh"

Error: Unable to access jarfile /home/johnDoe/AppServer/wildfly-10.1.0.Final/user_projects/domains/someStandAloneDomain/jboss-modules.jar

<----- this some additional informaiton I am printing to make the point
RESOLVED_JBOSS_HOME: /home/johnDoe/AppServer/wildfly-10.1.0.Final/user_projects/domains/someStandAloneDomain
{panel}

What the above panel shows is that the RESOLVED_JBOSS_HOME is not being properly set.

This clearly constrasts with the windows behavior, where my base script can correctly invoke a :
call jboss-cli.bat -f someFilepath 
and not break.

The reason for this seems that that while on windows, the script correctly makes no assumption on where the current working directory of the user is.
And only cares about the current location of the jboss-cli.bat script itself.

{panel}
if "%OS%" == "Windows_NT" (

  set "DIRNAME=%~dp0%" <-------- This here is a good approach

) else (

  set DIRNAME=.\

)
{panel}

On linux, the same is not being done:
{panel}
# Setup JBOSS_HOME
RESOLVED_JBOSS_HOME=`cd "$DIRNAME/.."; pwd` <-------- This is not a good approach if dirname is calculated based on the command line DIRNAME=`dirname "$0"`
if [ "x$JBOSS_HOME" = "x" ]; then
    # get the full path (without any relative bits)
    JBOSS_HOME=$RESOLVED_JBOSS_HOME
else
 SANITIZED_JBOSS_HOME=`cd "$JBOSS_HOME"; pwd`
 if [ "$RESOLVED_JBOSS_HOME" != "$SANITIZED_JBOSS_HOME" ]; then
   echo "WARNING JBOSS_HOME may be pointing to a different installation - unpredictable results may occur."
   echo ""
 fi
fi
export JBOSS_HOME
{panel}

I would suggest that linux scripts shouild cross cuttingly assume nothing about current working directory and do something like:

{panel}
#DIRNAME=`dirname "$0"`
DIRNAME="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
{panel}

Since I do not want to be corrupting my wildfly installation and I want to leave all scripts completely untouched, I will be changing my script invocation from:

{panel}
# source "$WILDFLY_BIN_DIRECTORY/jboss-cli.sh" --file="$fileNameWithoutPrefixSuffixQuotes"
/bin/bash "$WILDFLY_BIN_DIRECTORY/jboss-cli.sh" --file="$fileNameWithoutPrefixSuffixQuotes"
{panel}

Which is not Ideal, since in some scripts I may want to set in my run time environment variables like JAVA_OPTS to override the default ones used on start up of an app server.
So for me, in the ideal case, I would like to be able to use the source command to run any arbitrary script in the /bin folder without my current directory location playing any relevant role.


Kindest regards.
