Statuses

1. untracked
2. unmodified
3. modified
4. staged

untracked

• Newly created file what not connected to the any part of git.
• We use git add to connect these file to git.

unmodified

• Files connected to git but no changes were made yet.

modified

• Files connected to git and modified.
• When we do commit with this kind of resources only, no changes will be made.

staged

• Files connected to git and modified, and declared to commit next time.

Examples of an newly created file

Create a repository

kyle-no-MacBook:gitprac5 kyle$ git init
Initialized empty Git repository in /Users/kyle/tmp/gitprac5/.git/
kyle-no-MacBook:gitprac5 kyle$ 

Create a file

kyle-no-MacBook:gitprac5 kyle$ echo hoge > hoge.txt
kyle-no-MacBook:gitprac5 kyle$ git status
# On branch master
#
# Initial commit
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   hoge.txt
nothing added to commit but untracked files present (use "git add" to track)
kyle-no-MacBook:gitprac5 kyle$ 

• Now hoge.txt is untracked.

Add to Index

kyle-no-MacBook:gitprac5 kyle$ git add hoge.txt
kyle-no-MacBook:gitprac5 kyle$ git status
# On branch master
#
# Initial commit
#
# Changes to be committed:
#   (use "git rm --cached <file>..." to unstage)
#
#   new file:   hoge.txt
#
kyle-no-MacBook:gitprac5 kyle$ 

• Now README is staged (?).

Commit

kyle-no-MacBook:gitprac5 kyle$ git commit -m 'initial'
[master (root-commit) ffbe516] initial
 1 file changed, 1 insertion(+)
 create mode 100644 hoge.txt
kyle-no-MacBook:gitprac5 kyle$ git status
# On branch master
nothing to commit, working directory clean
kyle-no-MacBook:gitprac5 kyle$ 

• Now README is unmodified.

Cancel git add to new file

• We can cancel it like this:

kyle-no-MacBook:gitprac5 kyle$ echo README! > README
kyle-no-MacBook:gitprac5 kyle$ git status
# On branch master
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   README
nothing added to commit but untracked files present (use "git add" to track)
kyle-no-MacBook:gitprac5 kyle$ git add README
kyle-no-MacBook:gitprac5 kyle$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   new file:   README

# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   README
nothing added to commit but untracked files present (use "git add" to track)
kyle-no-MacBook:gitprac5 kyle$ 

• Also this deletes all of untracked files:

kyle-no-MacBook:gitprac5 kyle$ git clean -f
Removing README
kyle-no-MacBook:gitprac5 kyle$ ls -l

-rw-r--r--+ 1 kyle  staff  5  3  9 08:40 hoge.txt
kyle-no-MacBook:gitprac5 kyle$ git status

kyle-no-MacBook:gitprac5 kyle$ 

Examples of existing file that already tracked by git

kyle-no-MacBook:gitprac5 kyle$ echo hogehoge >> hoge.txt
kyle-no-MacBook:gitprac5 kyle$ git status
# On branch master
# Changes not staged for commit:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#   modified:   hoge.txt
#
no changes added to commit (use "git add" and/or "git commit -a")
kyle-no-MacBook:gitprac5 kyle$ 

• Now hoge.txt modified but not staged.

kyle-no-MacBook:gitprac5 kyle$ git add hoge.txt
kyle-no-MacBook:gitprac5 kyle$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   modified:   hoge.txt
#
kyle-no-MacBook:gitprac5 kyle$ 

• Now hoge.txt staged.
• Let's take one more modify.

kyle-no-MacBook:gitprac5 kyle$ echo hogehogehoge >> hoge.txt
kyle-no-MacBook:gitprac5 kyle$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#

#
# Changes not staged for commit:

#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#   modified:   hoge.txt
#
kyle-no-MacBook:gitprac5 kyle$ 

• This means last change (hogehogehoge) will not send by next commit.
• Next commit will send the change (hogehoge) only.
• So when you want to commit (hogehogehoge) next time, you need to execute git add once again.

kyle-no-MacBook:gitprac5 kyle$ git add hoge.txt
kyle-no-MacBook:gitprac5 kyle$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)

Environment

• WildFly 8.0.0.Final
• JBoss Tools (Kepler) 4.1.1.Final
• Eclipse Kepler SR1
• Oracle JDK7u51
• OS X 10.9.2

Test Servlet

• This time we're going to test it with enabling of assertion.

@WebServlet("/")
public class AssertServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        assert false : "test";
    }
}

Configure standalone.conf for launching through standalone.sh

• Add this statement to $WILDFLY_HOME/bin/standalone.conf

JAVA_OPTS=$JAVA_OPTS -ea

• This can be done on unix systems like this:

echo "JAVA_OPTS=\"\$JAVA_OPTS -ea\"" >> standalone.conf

• Now the Servlet throws Assertion Error when we launch WildFly through standalone.sh:

09:05:00,614 ERROR [io.undertow.request] (default task-1) UT005023: Exception handling request to /assert/: java.lang.AssertionError: test
    at assert0.AssertServlet.doGet(AssertServlet.java:16) [classes:]
    at javax.servlet.http.HttpServlet.service(HttpServlet.java:687) [jboss-servlet-api_3.1_spec-1.0.0.Final.jar:1.0.0.Final]
...

• But it won't work with WildFly instances that launched by Eclipse.

Configuring Eclipse

1. Open Servers view and double-click WildFly instance

2. Click “Open launch configuration”

3. Add “-ea” to “VM arguments:” - OK

wildfly-maven-plugin

• Like this:

                    <plugin>
                        <groupId>org.wildfly.plugins</groupId>
                        <artifactId>wildfly-maven-plugin</artifactId>
                        <version>1.0.1.Final</version>

                        <configuration>
                            <jboss-home>${wildfly.home}</jboss-home>
                            <modules-path>${wildfly.home}/modules</modules-path>
                            <jvm-args>-ea -Xms64m -Xmx512m -XX:MaxPermSize=256m
                                -Djava.net.preferIPv4Stack=true
                                -Djboss.server.base.dir=${wildfly.home}/standalone
                                -Djboss.socket.binding.port-offset=${wildfly.port.offset}</jvm-args>
                            <port>${wildfly.port.mgmt}</port>
                        </configuration>
...

Assertion notes

Eclipse

• We can enable assertion for every JUnit run configuration which will newly create.
  

• This won't make assertions enable for already created run configurations.

Maven Surefire Plugin

• “By default, Surefire enables JVM assertions for the execution of your test cases. To disable the assertions, set this flag to “false”[3].

Environment

Local

• VisualVM 1.7.0_51 (Build 1352-130117); platform 20130117-unknown-revn
• WildFly 8.0.0.Final
• Oracle JDK7u51
• OS X 10.9.2

Remote profiling target

• WildFly 8.0.0.Final
• Oracle JDK7u45
• OS X 10.9.1

Profiling local instances

• We don't need any special operation to profiling with local instances.
• After just launch VisualVM, we can see local instances.

Profiling Remote instances

Create a management user in the target instance

kyle-no-MacBook:bin kyle$ pwd
/Users/kyle/apps/wildfly-8.0.0.Final/bin
kyle-no-MacBook:bin kyle$ ./add-user.sh kyle ***
Picked up _JAVA_OPTIONS: -Dfile.encoding=UTF-8
Added user 'kyle' to file '/Users/kyle/apps/wildfly-8.0.0.Final/standalone/configuration/mgmt-users.properties'
Added user 'kyle' to file '/Users/kyle/apps/wildfly-8.0.0.Final/domain/configuration/mgmt-users.properties'
kyle-no-MacBook:bin kyle$ 

Define a system property in the target instance to accept connection from remote host

• CAUTION: this makes management port to accept connections from everyone.

/system-property=jboss.bind.address.management:add(value=0.0.0.0)

Launch VisualVM

• We have to specify an additional jar on startup option like this:

jvisualvm --cp:a /Users/kyle/apps/wildfly-8.0.0.Final/bin/client/jboss-cli-client.jar

• If it doesn't work, try “-cp:a” instead

Add and connect to target

1. Right-click “Remote” - “Add a remote host”

2. Enter hostname - OK

3. Right-click hostname - add a JMX connection

4. Enter connection url, username and password that created in above step - OK NOTICE: Usually, WildFly's management port is 9990. I customized it as 49990 for my environment.

5. Double-click a icon which appeared with JMX icon. now we can do profiling with remote WildFly instance.

service:jmx:http-remoting-jmx://[HOSTNAME]:9990

• In my last posting Treating environment specific configurations with Maven filtering, I said that I don't want to create separate files for each environment.
• But it is still needed by some cases.
  • Such as web.xml, logback.xml is too long for treat with Maven properties at some cases.
• So I'm going to find a way to achieve it.

Environment

• Apache Maven 3.1.1
• Jenkins 1.551
• WildFly 8.0.0.Final
• Eclipse Kepler SR1
• Oracle JDK7u51
• OS X 10.9.2

• We can place environment specific files in the folders named such as “_dev” or “_it”.
• Common resources among environments are can be placed on the regular place.
  • /webapp/WEB-INF/index.jsp and /src/main/resources/common.properties are regarded as common resources.
  • So they will be included for every environment.
• This mechanism supports both of /src/main/resources and /src/webapp, and /src/test/resources too.
• MainServet acquires all of properties, then dispatch to /WEB-INF/index.jsp, and return variables to the client.

How to apply this method to Jenkins job which executes integration test?

• We need to specify the profile named “test-with-wildfly”
• And appropriate environmentId on MAVEN_OPTS.

Test run

• integration-test phase executed expectedly.

Remarks

• I don't know whether it is good idea for any cases because we easily misses to keep these platform specific files correctly.
  • Sometimes we forget about these files need to be edited or created.
• So, I guess that we are better to apply this method for few numbers of resources that really required this way.

Unresolved issues

• Eclipse produces the package contains unnecessary resources.
• It seems to that exclusions are ignored.
• I guess this is not a problem for most cases, because correct environment specific resources are included.
