How to Install SVN (Sub version) in LINUX Machine?

Step By Step Configuring SVN Server in Linux


  •  Install apache/httpd 
yum install httpd
  • Make sure you apache is running. You can also type ‘http://localhost’ at your browser and apache test page should appear if your apache is running
/etc/rc.d/init.d/httpd start
OR
service httpd start
  • Make it start by default on startup
chkconfig httpd on

1. Change root user

su -
## OR ##
sudo -i

2. Install needed packages (mod_dav_svn and subversion)

yum install mod_dav_svn subversion

3. Modify Subversion config file /etc/httpd/conf.d/subversion.conf

Add following config to /etc/httpd/conf.d/subversion.conf file:
LoadModule dav_svn_module     modules/mod_dav_svn.so
LoadModule authz_svn_module   modules/mod_authz_svn.so
 
<Location /svn>
   DAV svn
   SVNParentPath /var/www/svn
   AuthType Basic
   AuthName "Subversion repositories"
   AuthUserFile /etc/svn-auth-users
   Require valid-user
</Location>

4. Add SVN (Subversion) users

Use following command:
## Create testuser ##
htpasswd -cm /etc/svn-auth-users testuser
New password: 
Re-type new password: 
Adding password for user testuser
 
## Create testuser2 ##
htpasswd -m /etc/svn-auth-users testuser2
New password: 
Re-type new password: 
Adding password for user testuser2
Note: Use exactly same file and path name as used on subversion.conf file. This example use /etc/svn-auth-users file.

5. Create and configure SVN repository

mkdir /var/www/svn
cd /var/www/svn
 
svnadmin create testrepo
chown -R apache.apache testrepo
 
 
## If you have SELinux enabled (you can check it with "sestatus" command) ##
## then change SELinux security context with chcon command ##
 
chcon -R -t httpd_sys_content_t /var/www/svn/testrepo
 
## Following enables commits over http ##
chcon -R -t httpd_sys_rw_content_t /var/www/svn/testrepo
Restart Apache:
/etc/init.d/httpd restart
## OR ##
service httpd restart
Goto http://localhost/svn/testrepo address and you should see something like following, write username and password:

SVN testrepo revision 0:


6. Configure repository

To disable anonymous access and enable access control add following rows to testrepo/conf/svnserve.conf file:
## Disable anonymous access ##
anon-access = none
 
## Enable access control ##
authz-db = authz

7. Create trunkbranches and tags structure under testrepo

Create “template” directories with following command:
mkdir -p /tmp/svn-structure-template/{trunk,branches,tags}
Then import template to project repository using “svn import” command:
svn import -m 'Initial import' /tmp/svn-structure-template/ http://localhost/svn/testrepo/
Adding         /tmp/svn-structure-template/trunk
Adding         /tmp/svn-structure-template/branches
Adding         /tmp/svn-structure-template/tags
 
Committed revision 1.
Check results on browser and see testrepo revision 1:

Ant Tutorial


ANT Tutorial

Apache Ant is a Java based build tool from Apache Software Foundation. Apache Ant's build files are written in XML and take advantage of the open standard, portable and easy to understand nature of XML.

Ant Uses :-

Before diving deep into the definition of Apache Ant, one must understand the need for a build tool. Why do I need Ant, or more specifically, why do I need a build tool?
Do you spend your day doing the following manually?
  • Compile code
  • Package the binaries
  • Deploy the binaries to the test server
  • Test your changes
  • Copy code from one location to another

Features of Apache Ant

  • Ant is the most complete Java build and deployment tool available.
  • Ant is platform neutral and can handle platform specific properties such as file separators.
  • Ant can be used to perform platform specific tasks such as modifying the modified time of a file using 'touch' command.
  • Ant scripts are written using plain XML. If you are already familiar with XML, you can learn Ant pretty quickly.
  • Ant is good at automating complicated repetitive tasks.
  • Ant comes with a big list of predefined tasks.
  • Ant provides an interface to develop custom tasks.
  • Ant can be easily invoked from the command line and it can integrate with free and commercial IDEs.

About SCM & PPT on SCM

             

SCM

Software configuration management is the discipline of managing the evolution of complex software systems [IEEE STD 1987].

Software configuration management is the process of identifying, organizing & controlling changes to the software during development & maintenance. SCM Operates throughout software development lifecycle (SDLC). From the software developer's perspective, SCM facilitates the development & change implementation activities.

The common features in a SCM tool are
* Support for controlling all types of file
* Managing changes
* Supporting branching & merging 
* Identifying & recreating releases 
* Providing a project view

Importance of SCM in SDLC SCM tools provide project managers with total control of the entire process of software development. It can track changes made to the code by developers and communicate status of documents and code as well as changes that have been made to them. 

 Configuration Management Activities :
* Configuration item/CM aggregate identification
* Promotion management 
* Release management 
* Branch management
* Variant Management
* Change Management


SDLC Life cycle





About Build and Release Engineer

                                   
About Build and Release Engineer

A Build and Release Engineer is a person who oversees the process of building and provides a company’s software to market/customers/End Users. Engineers in this industry must have strong problem-solving and analytical skills, and they must be comfortable with multi-tasking and working in a fast-paced environment in different environments. Companies often look for build release engineers who have four-year bachelor’s degrees or two-year master’s degrees in computer engineering or computer science, along with build automation experience and SCM. Professionals in the field often serve as liaisons among a company’s various departments, including operations, engineering, and quality assurance areas.

Building different applications for technologies such as cellular phones and making these applications available for manufacturing is a chief duty of an engineer in the software development field. For this reason, a build release engineer must be well-versed in a variety of computer programming languages in order to build these applications accurately. In addition, an engineer has to maintain and build automation scripts. He or she also needs to possess knowledge of various release procedures.

A build release engineer is responsible for researching ways to improve the software building process and for sharing production information with managers as well. After researching how to enhance software building tools and technologies, an engineer puts newly-researched tools to use so as to create build release process efficiency. The engineer is also required to produce regular reports and performance metrics to managers regarding how built applications are working. Professionals in the build release engineering field additionally create and release guidelines for a company’s products. Both oral and written communication skills thus are important parts of the job.

Another important duty of an engineer in the software building industry involves testing, as quality assurance is necessary to ensure that created software applications work properly to meet customer needs. A build release engineer must create test plans and then implement these plans so as to pinpoint problems that need to be addressed. These professionals additionally create tools to monitor production systems and perform data mining, which involves extracting data from large databases and turning them into valuable information that helps a company to make various decisions.

Developing bug tracking systems also is critical in the role of a person who builds software applications. Using these systems along with test plans, a build release engineer strives to solve problems by producing software improvements and re-creating software to be released. Build release engineers often work on deadline and must have solid critical thinking skills and work well under pressure.

Nant Tutorial

  Nant

NAnt is different.  Instead of a model where it is extended with shell-based commands, NAnt is extended using task classes.  Instead of writing shell commands, the configuration files are XML-based, calling out a target tree where various tasks get executed.  Each task is run by an object that implements a particular Task interface.
Granted, this removes some of the expressive power that is inherent in being able to construct a shell command such as 'find . -name foo -exec rm {}', but it gives you the ability to be cross-platform - to work anywhere and everywhere. And hey, if you really need to execute a shell command, NAnt has an <exec> task that allows different commands to be executed based on the OS it is executing on.

GIT Tutorial for Beginners

GIT Version Control

A version control system allows you to track the history of a collection of files and includes the functionality to revert the collection of files to another version. Each version captures a snapshot of the file system at a certain point in time. The collection of files is usually source code for a programming language but a typical version control system can put any type of file under version control.
The collection of files and their complete history are stored in a repository.

The process of creating different versions (snapshots) in the repository is depicted in the following graphic. Please note that this picture fits primarily to Git, another version control systems like CVS don't create snapshots but store file deltas.
