==Scripting==*1- '''Maven[http://ant.apache.org/manual/ Ant]''' My notes on -> [[User:Minooz/RepoSyncProj/Ant | Min Ant]]:A new ant script is created e.g. ''buildHudson.xml'' that triggers the target(assign1.test) of main build file(build.xml) of the project. See below:<source lang=java><project name="assign1" basedir="." default="myTarget"> <target name="assign1.build.call"> <!-- Call the target that does everything --> <ant antfile="build.xml" target="assign1.test"/> </target> <target name="myTarget.check" depends="assign1.build.call"> <echo>The assign1.build was called!</echo> </target></project></source>*2- '''Bash''' My notes on -> [[User:Minooz/RepoSyncProj/Bash | Min Bash]]
==Challenges==*1- I was receiving an error message while trying to do a new build on Hudson. It didn't let to clone the project on Hudson workspace. The error message is "Access is denied". So I had to delete the project and create a new one. Apparently one of the reasons is that Hudson doesn't let you queue the jobs. So, if you interrupt a job that is scheduled, you'Anthill''ll get the error message.*2- To run a bash script to build the project, there are 2 ways: :Execute Windows Batch Command: <source lang=bash>D:\cygwin\bin\bash /home/HudsonPrac/buildHudson.sh</source>:Invoke an Ant Script<source lang=java><project name="assign1" basedir="."> <target name="myTarget" > <exec executable="D:\cygwin\bin\bash" newenvironment="false"> <arg value="/home/HudsonPrac/buildHudson.sh"/> </exec> </target></project></source>*3- Since the bash script is running in Windows platform through Cygwin, there are some conflicts,so the PATH was changed to: PATH=/usr/bin:$PATHRead more about some conflicts [http://cygwin.com/cygwin-ug-net/using.html#using-pathnames here]*4- If there was an error applying a patch to a repository e.g. <code> hg import patch12.patch </code>, there might be a problem with line numbers merging issue. So, there will be an error created with this message: "Hunk #1 Failed". There are some ways to remove the hunks manually or just ignore that patch, if the later versions are fixed.: By "hunk" I mean a "snippet of change", i.e. a part of the "diff". TortoiseHg uses this terminology and so does darcs. – Deniz Dogan: For Hunk Failed message, first we need to make sure it's not applied before. Second thing to check is that bases are the same. All the revisions before that new changeset even with failed build should be applied before applying the successfully built change-set.*5- If there is an uncommited message, the script can not work properly, e.g. Rev is 18+. So, error should be displayed for the uncommited change-sets.*6- To run JUnit Tests from command line:: add the JUnit installation directory and the junit.jar file and also QTjava to the CLASSPATH. e.g. <code>CLASSPATH=".;D:\cygwin\home\java\junit3.0.1\junit.jar;C:\Program Files\java\jre6\lib\ext\QTjava"</code>: to run a sample AllTests class go to the installation directory and run: <code> java junit.textui.TestRunner junit.samples.AllTests </code>: to run NexJ AllTests do::: build the model: go to ws/core/build/ run <code> ant </code> or <code> ant -f build_JUnitTest.xml</code> :: from command line: go to ws/out/core/ run <code> java junit.textui.TestRunner nexj.core.AllTests</code> (getting error IOExcpetion) so we just ran one test file <code> java junit.textui.TestRunner nexj.core.util.MathUtilTest</code> (We did some changes to <code> core/test/nexj/core/util</code> to practice with it) Or we can run the ant target for test: <code> ant -f build_JUnitTest.xml test </code>*7- Bugs after implementation at NexJ
:-Change SourcesNexJ Internal repo has several branches, which create a Change object each time something is modified in the VC repository. Most ChangeSources listen for messages from a hook script of some sort. Some sources actively poll the repository on a regular basis. All Changes are fed to the Schedulers.:- Schedulers, which decide and when builds should be performed. They collect Changes into BuildRequestscloning and pulling, which are then queued for delivery we just needed to Builders until mention it as a buildslave is availabledefault branch, to not to confuse revision numbers and latest changesets.:-BuildersSince the decimal part of the revision number will keep changing from computer to computer, which control exactly how each build is performed it was preferred to use the global hex chagesetID (with a series of BuildSteps, configured in a BuildFactoryGUID). Each Build is run on a single buildslave.:-Status pluginsSo, which deliver information about the build results through protocols like HTTP, mail, and IRC.*Common Requirements:At a bare minimum, you'll need first big change was adding this command to get the following for both list of latest changesets up to the buildmaster and a buildslavetip::-Python: http://www.python.org Buildbot requires python<code>hg log ${IntDir} -2.4 or later.r ${PrevRev}:-Twisted: http://twistedmatrix.com (Twisted is an eventb default -driven networking engine written in Python and licensed under the MIT license.):Requirements for Buildmaster:-sqlite3: http:template '{node}\n'<//pypi.python.org/pypi/pysqlitecode>::The sqlite3 package is required for python-2.5 and earlier (it is already included in python-2.5 and later, but This number will also be added to the version in python-2.5 has nasty bugs):-simplejson: http://pypi.python.org/pypi/simplejson::The simplejson package is required for python-2.5 and earlier (it is already included as json in python-2.6 and later):-Jinja2: http://jinja.pocoo.org/2::Jinja2 is a general purpose templating language and is used by Buildbot to generate commit summary while importing the HTML output.==To Learn==: [[User:Minooz/Ant | Min Ant]]: [[User:Minooz/Mercurial | Min Mercurial]]: [[User:Minooz/Ant | Min Ant]]patch from Internal repo
