Bug 591003

Description of problem:

Errors in the file /usr/share/cluster/tomcat-5.sh resource script, part of rgmanager, that leaves the script unusable.


Version-Release number of selected component (if applicable):

rgmanager-2.0.52-6.el5

How reproducible:

Always


Steps to Reproduce:
1. Use the attached /etc/cluster/cluster.conf


2. Use the attached /etc/tomcat5/tomcat5.conf


3. Use the attached /etc/tomcat5/server.xml



4.- start cluster services cman and rgmanager

service cman start
service rgmanager start

5.- Use "rg_test" to enable the Artifactory01 service

rg_test test /etc/cluster/cluster.conf start service Artifactory01

  
Actual results:

1.- "rg_test" says the Service is started, when it doesn't. There are no java processess running on the system

2.- Checking /etc/cluster/tomcat-5/tomcat-5:Artifactory01/logs/catalina.out the problem is due to a problem with the "su" invocation line at /usr/share/cluster/tomcat-5.sh resource script:

su "$TOMCAT_USER" -c "$JAVA_HOME/bin/java" $JAVA_OPTS $OCF_RESKEY_catalina_options \
                -Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \
                -Dcatalina.base="$TOMCAT_gen_catalina_base" \
                -Dcatalina.home="$CATALINA_HOME" \
                -Djava.io.tmpdir="$CATALINA_TMPDIR" \
                org.apache.catalina.startup.Bootstrap "$@" start \
                >> "$TOMCAT_gen_catalina_base"/logs/catalina.out 2>&1 &


Changing it to the following it is fixed:

 su "$TOMCAT_USER"  -c " \"$JAVA_HOME/bin/java\" $JAVA_OPTS $OCF_RESKEY_catalina_options \
                -Djava.endorsed.dirs=\"$JAVA_ENDORSED_DIRS\" -classpath \"$CLASSPATH\" \
                -Dcatalina.base=\"$TOMCAT_gen_catalina_base\" \
                -Dcatalina.home=\"$CATALINA_HOME\" \
                -Djava.io.tmpdir=\"$CATALINA_TMPDIR\" \
                org.apache.catalina.startup.Bootstrap \"$@\" start " \
                >> "$TOMCAT_gen_catalina_base"/logs/catalina.out 2>&1 &


3.- There are errors in the parsing of the generated server.xml file in catalina.out  ue to its usage of commented lines in the "sha1_addToFile" function defined in the /usr/share/cluster/utils/config-utils.sh file:

sha1_addToFile()
{
        declare sha1line="# rgmanager-sha1 $(sha1sum "$1")"
        echo $sha1line >> "$1"
}

Adding the following function to /usr/share/cluster/utils/config-utils.sh will fix it:

sha1_addToFileXML()
{
        declare sha1line="<!--\n# rgmanager-sha1 $(sha1sum "$1") \n-->"
        echo -e $sha1line >> "$1"
}

Also it is necessary to change the line of /usr/share/cluster/tomcat-5.sh

        sha1_addToFile "$generated_file"

to the following:

        sha1_addToFileXML "$generated_file"

4.- Changing the the file /etc/tomcat5/server.xml causes the tomcat-5.sh resource script re-generate its own server.xml file located at /etc/cluster/tomcat-5/tomcat-5:Artifactory01/conf/server.xml, but the regeneration concatenates the contents with the previous file causing more parsing errors in catalina.out . This is due to the "generate_config_file" function located in /usr/share/cluster/tomcat-5.sh

generate_config_file()
{
	declare original_file="$1"
	declare generated_file="$2"
	declare ip_addresses="$3"

	if [ -f "$generated_file" ]; then
		sha1_verify "$generated_file"
		if [ $? -ne 0 ]; then
			clog_check_sha1 $CLOG_FAILED
			return 0
		fi
	fi	

	clog_generate_config $CLOG_INIT "$original_file" "$generated_file"

#	generate_configTemplate "$generated_file" "$original_file"
	$(dirname $0)/utils/tomcat-parse-config.pl $ip_addresses < "$original_file" >> "$generated_file"

        sha1_addToFile "$generated_file"
	clog_generate_config $CLOG_SUCCEED "$original_file" "$generated_file"
               
	return 0;
}


Changing it to the following will fix it:

generate_config_file()
{
	declare original_file="$1"
	declare generated_file="$2"
	declare ip_addresses="$3"

	if [ -f "$generated_file" ]; then
		sha1_verify "$generated_file"
		if [ $? -ne 0 ]; then
			clog_check_sha1 $CLOG_FAILED
		else
			return 0
		fi
		
	fi	

	clog_generate_config $CLOG_INIT "$original_file" "$generated_file"

#	generate_configTemplate "$generated_file" "$original_file"
	$(dirname $0)/utils/tomcat-parse-config.pl $ip_addresses < "$original_file" > "$generated_file"

        sha1_addToFileXML "$generated_file"
	clog_generate_config $CLOG_SUCCEED "$original_file" "$generated_file"
               
	return 0;
}


Expected results:

1.- Detection of Tomcat not starting. In this case we used "rg_test", so it's a minot bug

2.- No errors, Tomcat started

3.- No parsing errors in catalina.out

4.- No parsing errors in catalina.out
