Catastrophic Backtracking

RegExp Playground

This repository contains several regexp examples.

Examples

1. Catastrophic Backtracking

This is Java example of backtracking catastrophic shown in Coding Horror post This is a known behavior when using nesting repetition operators, that has been analyzed in stackoverlow, regular expressions dedicated sites.
It can be seen the exponential explosion that take to parse using regexp for a simple pattern:
(x+x+)y+
Details of this issue can be found on the above links.

Execute

mvn clean package
mvn exec:java -Dexec.mainClass="cl.devweb.regexp.exploit.CatastrophicBacktracking"

Rule of Thumb - Solution

The solution is simple. When nesting repetition operators, make absolutely sure that there is only one way to match the same match. If repeating the inner loop 4 times and the outer loop 7 times results in the same overall match as repeating the inner loop 6 times and the outer loop 2 times, you can be sure that the regex engine will try all those combinations.

OUTPUT

 mvn exec:java -Dexec.mainClass="cl.devweb.regexp.exploit.CatastrophicBacktracking"

Maven Cheat Sheet

Some reminder for Maven:

mvn clean package -DskipTests -Dmaven.javadoc.skip=true -Dhttps.protocols=TLSv1.2

1. Use a different settings.xml
mvn --settings ~/.m2/YourOwnSettings.xml clean install
or
mvn -s ~/.m2/YourOwnSettings.xml clean install

2. Jboss tasks:
 mvn jboss-as:deploy
 mvn jboss-as:redeploy
 mvn jboss-as:undeploy

3. Eclipse Maven clean:
(retired)
mvn eclipse:eclipse
mvn eclipse:clean
mvn install

4. set java version:
<project>
 [...]
 <build>
 [...]
 <plugins>
 <plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-compiler-plugin</artifactId>
 <version>3.5.1</version>
 <configuration>
 <source>1.4</source>
 <target>1.4</target>
 </configuration>
 </plugin>
 </plugins>
 [...]
 </build>
 [...]
</project>

or

  <properties>
    <maven.compiler.source>11</maven.compiler.source>
    <maven.compiler.target>11</maven.compiler.target>
  </properties>
 
  


5. Missing Maven dependencies in Eclipse Project

   workaround to have an eclipse maven project


6. basic maven structure

src/main/java

 - src 
    - main 
          - java 
          - resources 
          - webapp 
     - test 
          - java 
          - resources 

- target

7. packaging:

<packaging>jar</packaging>

8. executing from maven:

add the following plugin to pom.xml:
<plugin>
 <groupId>org.codehaus.mojo</groupId>
 <artifactId>exec-maven-plugin</artifactId>
 <version>1.2.1</version>
 <configuration>
 <mainClass>com.myorganisationname.common.App</mainClass>
 </configuration>
<arguments> -Dlog4j.configurationFile=/tmp/log4j2.xml </arguments> <classpathScope>test</classpathScope> 
</plugin>

and run it with:

mvn exec:java

9. skipping test:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<skipTests>true</skipTests>
</configuration>
</plugin>
      or
 
      mvn install -DskipTests
 

 
     or
     mvn install -Dmaven.test.skip=true
 
 
10. Multiple Module Projects
<packaging>pom</packaging>

<modules>
<module>guide-ide-eclipse-site</module>
<module>guide-ide-eclipse-core</module>
<module>guide-ide-eclipse-module1</module>
</modules>


Add the parent to the POMs of the new modules:

 <parent>
 <groupId>guide.ide.eclipse</groupId>
 <artifactId>guide-ide-eclipse</artifactId>
 <version>1.0-SNAPSHOT</version>
 </parent>


mvn install
mvn eclipse:eclipse

http://maven.apache.org/plugins/maven-eclipse-plugin/reactor.html


11. web archetype
mvn archetype:generate -DgroupId=cl.devweb -DartifactId=wls_log_retrieval -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false
12. copy dependencies:
 mvn dependency:copy-dependencies -DoutputDirectory=OUTPUT_DIR

13. tomcat
mvn tomcat7:deploy
mvn tomcat7:undeploy
mvn tomcat7:redeploy

14. verbose class
mvn test -DjvmArgs="-verbose:class"

15. web.xml-less
(servlet 3.0+)

<plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-war-plugin</artifactId>
 <version>2.6</version>
 <configuration>
  <failOnMissingWebXml>false</failOnMissingWebXml>
 </configuration>
</plugin> 
 
 
16. weblogic
 
              mvn com.oracle.weblogic:weblogic-maven-plugin:deploy

           mvn com.oracle.weblogic:weblogic-maven-plugin:undeploy


            <plugin>
                <groupId>com.oracle.weblogic</groupId>
                <artifactId>weblogic-maven-plugin</artifactId>
                <version>12.1.3-0-0</version>
                <configuration>
                    <adminurl>t3://127.0.0.1:7001</adminurl>
                    <user>weblogic</user>
                    <password>welcome1</password>
                    <upload>true</upload>
                    <action>deploy</action>
                    <remote>true</remote>
                    <verbose>true</verbose>
                    <source>target/${project.artifactId}.${project.packaging}</source>
                    <name>${project.artifactId}</name>
                    <targets>AdminServer</targets>
                </configuration>
            </plugin>
 
17. debug flag
mvn -X
or
mvn -e

18. update (when it does not find jar)
mvn -U package

19. dependencies
mvn dependency:tree
     -Dverbose

 
20. skip javadoc
-Dmaven.javadoc.skip=true
  
 
21. assigning different https protocol version :
(to avoid: Received fatal alert: protocol_version)

-Dhttps.protocols=TLSv1.2

22. identifying excluding dependencies

mvn dependency:tree -Dverbose -Dincludes=log4j:log4j

i.e.:


[German@KDU foo-ejemplo (feature/ggonzalez/refactoring)]$ mvn dependency:tree -Dverbose -Dincludes=org.springframework:spring-core

23. Add local dependencies directly 

<dependency>
 <groupId>com.sample</groupId>
 <artifactId>sample</artifactId>
 <version>1.0</version>
 <scope>system</scope>
 <systemPath>${project.basedir}/src/main/resources/yourJar.jar</systemPath>
</dependency>



        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>3.2.0</version>
            <configuration>
                <failOnMissingWebXml>true</failOnMissingWebXml>
                <webResources>
                    <resource>
                       <directory>${project.basedir}/lib</directory>
                       <targetPath>WEB-INF/lib</targetPath>
                    </resource>
                </webResources>
            </configuration>
        </plugin>   
  


24. purge local
to clean up old dependencies (when someone changes a library but didn't upgrade the version, so we have a stale version)

mvn clean dependency:purge-local-repository 



 
25. maven options for -XX

export MAVEN_OPTS="-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/tmp/"


<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
      <argLine>-Xms512m -Xmx512m -XX:PermSize=256m -XX:+HeapDumpOnOutOfMemoryError -XX:MaxPermSize=512m</argLine>
    </configuration>
  </plugin>
</plugins>


<properties>
<argLine>-Xms512m -Xmx512m -XX:PermSize=256m -XX:+HeapDumpOnOutOfMemoryError -XX:MaxPermSize=512m</argLine>

        </target>
    </configuration>
</execution>


39. Owasp Dependency-check-maven
open source vulnerable libraries.

mvn dependency-check:check

            <plugin>
                <groupId>org.owasp</groupId>
                <artifactId>dependency-check-maven</artifactId>
                <version>5.2.4</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>check</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>


40. Modernizer Maven Plugin
yet another static analyzer

<plugin>
  <groupId>org.gaul</groupId>
  <artifactId>modernizer-maven-plugin</artifactId>
  <version>2.0.0</version>
  <configuration>
    <javaVersion>1.8</javaVersion>
  </configuration>
</plugin>



41. springboot startup

mvn spring-boot:run
 
 
42. javadoc plugin

mvn javadoc:javadoc

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-javadoc-plugin</artifactId>
                <version>2.9.1</version>
                <executions>
                    <execution>
                        <id>attach-javadocs</id>
                        <goals>
                            <goal>jar</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>


43. Overriding managed version maven dependency

parent pom spring boot 2.x
version 1.x can override a version easily by replacing properties of a library:

<properties>
 <json.version>20180130</json.version>
</properties>


however now with 2.0 it must be avoided to use parent starter and add manually each dependency. From 1, 2 & 3


<dependencyManagement>
 <dependencies>
 <dependency>

...
...
...


44. logging stdout
Maven can log with:

-l log file
--log-file log.txt

or using tee would be better (we can redirect stdout to a file)

mvn-all2.bat | tee /a log3.txt



45. profile command line
to execute a profile (by using the maven repository) use -P argument:

mvn clean package -P perfil

    <profiles>
        <profile>
            <id>perfil</id>
            <repositories>
                <repository>
                    <snapshots>
                        <enabled>false</enabled>
                    </snapshots>
                    <id>company-releases</id>
                    <name>company-releases</name>
                    <url>https://host:port/repository/maven-releases</url>
                </repository>


46. internal repository in pom.xml

<project>
  ...

 <repositories>
   <repository>
         <id>my-internal-site</id>
         <url>http://myserver/repo</url>
    </repository>
  </repositories>
