Install and Setup Koha to use Git on a Development Server

Prerequisites

Installed a minimal debian system, sudo, vim, xorg, xterm, wdm, fluxbox, idesk, and iceweasel. (idesk is used for desktop icons in the fluxbox window manager.)

Add Koha Sources

Prevent annoying password prompts:

 sudo ls

Create the file /etc/apt/sources.list.d/koha.list:

 echo deb http://debian.koha-community.org/koha-staging unstable main | sudo tee /etc/apt/sources.list.d/koha.list 

Add the Keys:

 wget -O- http://debian.koha-community.org/koha/gpg.asc | sudo apt-key add - 

Update the Sources:

 sudo apt-get update

Install Koha

Make sure you have fully updated your machine:

 sudo apt-get update 
 sudo apt-get upgrade 

Install koha-common:

 sudo apt-get install koha-common 

Setup Koha

Enable the Apache Rewrite Module:

 sudo a2enmod rewrite 

Create a koha instance and Create the koha database:

 sudo koha-create --create-db instancename 

Make sure the koha site is enabled:

 sudo a2ensite koha 

Edit the Apache2 ports.conf file to listen on port 8080:

 sudo vi /etc/apache2/ports.conf 

Insert the following line after the NameVirtualHost line for port 80:

 NameVirtualHost *:8080 

Insert the following line after the Listen line for port 80:

 Listen 8080 

Restart Apache2:

 sudo /etc/init.d/apache2 restart 

Find the passwords for koha:

 sudo less /etc/koha/sites/instancename/koha-conf.xml 

(You need the user and password near the end of the file to login to the setup page.)

Start fluxbox:

 startx 

Open the Iceweasel web browser:

 Right-Click->Applications->Network->Web Browsing->Iceweasel 

Start Koha Setup:

 http://localhost:8080 

Follow the onscreen instructions.

Install and Setup Git

Git is typically used for Development, Testing Bugs, Fixing Bugs, and Signing-Off on bug patches. (Git is not what you want for a typical Live/Production Server.)

---

Install Git:

 sudo apt-get install git

Set your name and mail address in git:

 git config --global user.name "Your NAME"
 git config --global user.email "your@mail.com" 

Set up a SMTP server using gmail:

 git config --global sendemail.smtpserver smtp.gmail.com
 git config --global sendemail.smtpserverport 587
 git config --global sendemail.smtpencryption tls
 git config --global sendemail.smtpuser your_email@gmail.com
 git config --global sendemail.smtppass your_password 

Automatically fix whitespace errors in patches:

 git config --global core.whitespace trailing-space, space-before-tab
 git config --global apply.whitespace.fix 

Set Syntax Highlighting/Color UI:

 git config --global color.ui auto 

For further Git Configuration help:

 http://git-scm.com/book/en/Customizing-Git-Git-Configuration 

Clone the public repository:

 cd ~/
 git clone git://git.koha-community.org/Koha-community/Koha.git kohaclone

(See Appendix B for HTTP instructions, if you are unable to connect to port 9418 on git.koha-community.org.)

Create a branch to work on:

 cd kohaclone
 git checkout -b mywork origin/master

(You want to apply patches to the origin/master branch for testing.)

Install and run koha-gitify, which maps config files to a koha.git repo

Install koha-gitify

 cd ~/
 git clone https://gitlab.com/koha-community/koha-gitify.git
 cd koha-gitify
 sudo make install

run koha-gitity on koha instance 'kohadev1'

 sudo koha-gitify kohadev1 /home/user1/kohaclone

Update missing perl missing dependencies

Search for Missing Dependencies:

 cd ~/kohaclone
 ./koha_perl_deps.pl -m 

Mine displayed 2 missing dependencies:

 Crypt::Eksblowfish::Bcrypt
 Data::Pagination

(Note that it shows which Modules are Required.) (Crypt::Eksblowfish::Bcrypt is a required module.)

Install Missing Dependencies:

 sudo install libcrypt-eksblowfish-perl 

Restart services

 sudo service memcached restart
 sudo service koha-common restart
 sudo service apache2 restart
 

Navigate to localhost:8080: It may require you to upgrade the database and run another web installer, but shouldn't go through the whole web install again. Login with the Username/Password for the superlibrarian account you have created. Otherwise login with the user/pass specified in the /etc/koha/sites/instancename/koha-conf.xml. Then Create a superlibrarian account, log off, and login with the new superlibrarian account.

Working with git

Create a bugzilla report for the bug you are fixing, if a bug has not already been reported:

 http://bugs.koha-community.org/ 

Now you do some work. Such as editing a template file that is messed up or editing a file to fix a bug. Commit the file once you have finished making changes to the file.

Commit the file:

 git commit file

(Use "git commit -a" for a bunch of files.) You'll be asked to enter a comment for your patch. Start the first line with the bugzilla number.

"Bug NNNN blabla bla full description of what my patch does continued contnued ... "

Add [ENH] just after the patch number, if your patch is an Enhancement. (Instead of a bug fix.)

Show how your commit fits with all the other commits in this branch/clone:

 git log 

Update Git

Save your changes, Update git, Restore your changes:

 git stash save
 git fetch
 git rebase origin/master
 git stash apply 

Update git and wipeout your changes:

 git fetch
 git rebase origin/master 

Share git patch with the rest of the world

Create a patch and send it to the QA Manager:

 git format-patch origin
 git send-email 0001-filename 

Deleting Branches in git

Delete a branch:

 git branch -D branchname 

Delete multiple branches at once:

 git branch | grep "^ bug_" | xargs git branch -D 

Testing a patch using git and Signing-Off

Download the patch:

 wget -O <name_of_patch_file> http://bugs.koha-community.org/bugzilla3/attachment.cgi?id=<attachment_number>

(Or just go to the bugzilla page and download it using a web browser.)

Apply the Patch:

 git checkout -b qa_bug_xxxx
 git am -3 -i -u <name_of_patch_file>

Test it: Test the functionality of the patch. Does it do what is says it does? Does it do something it shouldn't?

Finish testing by running the following automated tests:

 prove t/ 
 prove t/db_dependent 
 prove xt/ 
 prove xt/author

(For all of the tests is xt/author to complete, you need the following perl modules:)

(Test::Pod, Test::Pod::Spelling, and Text::CSV::Unicode.)

Signing-Off:

Create a new signed-off patch, if the patch you tested is ok:

 git format-patch -s -l origin/master 

Attach the Signed-Off patch to the bugzilla post, and mark the bug as Signed-Off.
