Subject [jira] [Created] (IGNITE-2891) Can't start ggvisorui.sh (ignite.sh etc) on CygWIN
Date Thu, 24 Mar 2016 18:39:25 GMT
knivit created IGNITE-2891:
------------------------------

             Summary: Can't start ggvisorui.sh (ignite.sh etc) on CygWIN
                 Key: IGNITE-2891
                 URL: https://issues.apache.org/jira/browse/IGNITE-2891
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 1.5.0.final
            Reporter: knivit
            Priority: Minor


[ PROBLEM ]
I've tried to start ggvisorui on CygWIN and got a fatal error:
{code}
$ uname && pwd
CYGWIN_NT-10.0
/home/user/gridgain-enterprise-fabric-7.5.8

$ ./bin/ggvisorui.sh &
[1] 10340
Error: Could not find or load main class org.gridgain.visor.gui.VisorGuiLauncher
{code}

[ INVESTIGATION ]
$IGNITE_HOME is set incorrectly in these scripts:
{code}
$ fgrep -ir -n -A 2 'cygwin' bin/
bin/include/build-classpath.sh:38:    CYGWIN*)
bin/include/build-classpath.sh-39-        SEP=";";
bin/include/build-classpath.sh-40-        export IGNITE_HOME=`echo $IGNITE_HOME | sed -e 's/^\/\([a-zA-Z]\)/\1:/'`
--
bin/include/functions.sh:148:        CYGWIN*)
bin/include/functions.sh-149-            SEP=";";
bin/include/functions.sh-150-            export IGNITE_HOME=`echo $IGNITE_HOME | sed -e 's/^\/\([a-zA-Z]\)/\1:/'`
--
bin/include/setenv.sh:48:    CYGWIN*)
bin/include/setenv.sh-49-        SEP=";";
bin/include/setenv.sh-50-        export IGNITE_HOME=`echo $IGNITE_HOME | sed -e 's/^\/\([a-zA-Z]\)/\1:/'`
{code}
bin/include/functions.sh is sourced everywhere (ggvisurui.sh, ignite.sh etc) so they don't
work.

The cause is in using sed:
{code}
$ IGNITE_HOME=/home/user/gridgain-enterprise-fabric-7.5.8
$ echo $IGNITE_HOME | sed -e 's/^\/\([a-zA-Z]\)/\1:/'

h:ome/user/gridgain-enterprise-fabric-7.5.8
{code}

[ SOLUTION ]
There is a standard utility to do the work properly:
{code}
$ IGNITE_HOME=/home/user/gridgain-enterprise-fabric-7.5.8
$ cygpath --path --windows $IGNITE_HOME
D:\cygwin64\home\user\gridgain-enterprise-fabric-7.5.8
{code}

BTW why the same code repeated three times ? 
And check this:
{code}
getClassPathSeparator() {
    SEP=":";

    case "`uname`" in
        MINGW*)
            SEP=";";
            export IGNITE_HOME=`echo $IGNITE_HOME | sed -e 's/^\/\([a-zA-Z]\)/\1:/'`
            ;;
        CYGWIN*)
            SEP=";";
            export IGNITE_HOME=`echo $IGNITE_HOME | sed -e 's/^\/\([a-zA-Z]\)/\1:/'`
            ;;
    esac
}
{code}
A function with a name like "getClassPathSeparator" should NOT change anything (get... means
a getter).
