A collection of tools and scripts for creating one or more CiviCRM development/demo/testing environments.

• Shell (bash)
• Git/SVN
• PHP
• MySQL (client/server)
• Recommended: Apache (TODO: nginx)
• Recommended: Ruby/Rake

git clone https://github.com/civicrm/civicrm-buildkit.git
cd civicrm-buildkit/bin
./civi-download-tools
./amp config
## At this point, check to make sure you follow the instructions output by amp config,
## which involve adding a line to your Apache configuration file
./amp test
./civibuild create drupal-demo --civi-ver 4.5 --url http://localhost:8001
## FIXME: ./civibuild launch drupal-demo

The final command will print out URLs and credentials for accessing the website.

civicrm-buildkit includes several utilities which are useful in developing CiviCRM:

• amp - Abstracted interface for local httpd/sql service (Apache/nginx/MySQL)
• civibuild - CLI tool which builds a complete source tree (with CMS+Civi+addons), provisions httpd/sql, etc.
• civicrm-upgrade-test - Scripts and data files for testing upgrades
• composer - Dependency manager for PHP packages
• civix - Code-generator for CiviCRM extensions
• git-scan - Git extension for working with many git repositories
• hub - Git extension for easily working with GitHub (Note: Requires Ruby/Rake)
• drush - CLI administration tool for Drupal
• wp - CLI administration tool for WordPress

It will be handy to add these to your PATH:

export PATH=/path/to/civicrm-buildkit/bin:$PATH

(Note: Adjust as needed for your filesystem.) To automatically set this up again each time you login, add the statement to ~/.bashrc or ~/.profile .

If you have already installed these tools or don't want them, then simply skip this step.

civicrm-buildkit includes a small library of build scripts for different configurations. For example, at time of writing, it includes:

• drupal-clean: A bare, "out-of-the-box" installation of Drupal+CiviCRM
• drupal-demo: A demo site running Drupal and CiviCRM
• wp-demo: A demo site running WordPress and CiviCRM
• symfony: An experimental hybrid site running Drupal 7, Symfony 2, and CiviCRM
• extdir: A mock website akin to civicrm.org/extdir/ . Useful testing the extension download process.

For a list of available build-types as well as documentation on writing build scripts, see app/config.

If you're interested in working on the build types or build process, then the workflow will consist of alternating two basic steps: (1) editing build scripts and (2) rebuilding. Rebuilds may take a few minutes, so it's helpful to choose the fastest type of rebuild that will meet your needs.

There are four variations on rebuilding. In order of fastest (least thorough) to slowest (most thorough):

(TODO: Write a real tutorial!)

Suppose we've just downloaded buildkit and want to prepare a patch for CiviCRM 4.6. This requires downloading and installing the bleeding edge (4.6.x) code for CiviCRM+CMS as well as writing and publishing the patch.

## Download Drupal 7.x and CiviCRM 4.5.x
civicrm-buildkit$ civibuild create drupal-demo --civi-ver 4.5 --url http://localhost:8001

## Create a "fork" of civicrm-core on github.com for publishing changes
civicrm-buildkit$ cd build/drupal-demo/sites/all/modules/civicrm
civicrm$ hub fork

## Create some changes locally
civicrm$ git checkout origin/4.5 -b 4.5-mypatch
civicrm$ vi CRM/Utils/Array.php
civicrm$ git commit CRM/Utils/Array.php

## Publish our changes on github.com
civicrm$ git push mygithubuser 4.5-mypatch
civicrm$ hub pull-request -b 4.5

Please note: A build may include several different git repositories. The commands should look about the same on any repository, although different git repositories may use different names for their versions/branches (eg the civicrm-core, civicrm-joomla, and civicrm-wordpress repositories have branches named "4.5", but the civicrm-drupal repository has a branch named "7.x-4.5").

(TODO: Write a real tutorial!)

From time-to-time, you may want to update your code. It's also a good idea to double-check that your git repos have checked out the normal/expected branches.

civicrm-buildkit$ cd build/drupal-demo

drupal-demo$ git scan status
## If any repos look unclean, figure out why... and clean them up!

## Then:
drupal-demo$ git scan update

## If you think the DB or config structure has changed, then optionally:
drupal-demo$ civibuild reinstall drupal-demo

civicrm-buildkit$ cd build/drupal-demo/sites/all/modules/civicrm/tools

## Run all the API tests
tools$ ./scripts/phpunit api_v3_AllTests

## Run a single test class
tools$ ./scripts/phpunit api_v3_ContactTest

## Run a single test function in a single test class
tools$ ./scripts/phpunit --filter testCreateNameOrganization api_v3_ContactTest

When one makes a schema change, one must also prepare and test an upgrade script. The basic cycle is:

1. Modify the upgrade script (*.mysql or *.php -- eg CRM/Upgrade/Incremental/php/FourFive.php)
2. Load a DB snapshot from an older version (e.g. CiviCRM 4.3.0)
3. Execute the upgrade script
4. Repeat until the upgrade works as expected

You can do these steps manually. Of course, it's a bit tedious to generate and track the DB snapshots while reloading them and rerunning the upgrade logic. If you're particularly impatient/mindless (like me), you can use the command:

civibuild upgrade-test BUILDNAME SQLFILE

For example:

civicrm-buildkit$ cd build/drupal-demo/sites/all/modules/civicrm
civicrm$ vi CRM/Upgrade/Incremental/php/FourFive.php
civicrm$ civibuild upgrade-test drupal-demo 4.3.0-setupsh.sql.bz2
## Uhoh, that didn't work! Try again...
civicrm$ vi CRM/Upgrade/Incremental/php/FourFive.php
civicrm$ civibuild upgrade-test drupal-demo 4.3.0-setupsh.sql.bz2
## Hooray! It worked.

The file "4.3.0-setupsh.sql.bz2" is a standard DB snapshot bundled with buildkit -- it contains a database from CiviCRM 4.3.0 with randomly-generated data. The "upgrade-test" command will load "4.3.0-setupsh.sql.bz2", execute a headless upgrade, and write any errors to the log. (See console output for details.)

Of course, it's fairly common to encounter different upgrade issues depending on the original DB -- an upgrade script might work if the original DB is v4.3 but fail for v4.2. It's a good idea to test your upgrade logic against multiple versions:

civicrm$ civibuild upgrade-test drupal-demo '4.2.*' '4.3.*' '4.4.*'

All of the tests above use standard DB snapshots with randomly-generated data. If you want to test something more specific, then create your own DB snapshot and use it, eg:

## Make your own DB with weird data; save a snapshot
civicrm$ echo "update civicrm_contact set weird=data" | mysql exampledbname
civicrm$ mysqldump exampledbname | gzip > /tmp/my-snapshot.sql.gz
## Write some upgrade logic & try it
civicrm$ vi CRM/Upgrade/Incremental/php/FourFive.php
civicrm$ civibuild upgrade-test drupal-demo /tmp/my-snapshot.sql.gz
## Uhoh, that didn't work! Try again...
civicrm$ vi CRM/Upgrade/Incremental/php/FourFive.php
civicrm$ civibuild upgrade-test drupal-demo /tmp/my-snapshot.sql.gz
## Hooray! It worked.

If at any point you need to backout and load a "known-working" database, then use the DB created by the original build:

$ civibuild restore drupal-demo

There are a few CiviCRM settings which are commonly configured on a per-server or per-workstation basis. For example, civicrm.org's demo server has ~10 sites running different builds (Drupal/WordPress * 4.4/4.5 * CiviCRM/CiviHR), and visitors should not be allowed to download new extensions on any of those sites. However, on the training server, trainees should be allowed to download extensions. As discussed in Override CiviCRM Settings, this setting (and many others) can be configured in civicrm.settings.php.

The civicrm.settings.php is created automatically as part of the build. One could edit the file directly, but that means editing civicrm.settings.php after every (re)build. The easiest way to customize the settings is to put extra *.php files in /etc/civicrm.settings.d -- these files will be loaded on every site that runs on this server (regardless of how many sites you create or how many times you rebuild them).

For more details on how civicrm.settings.d works, see app/civicrm.settings.d/README.txt.

A parallel structure exists for the CMS settings files. See also:

• app/drupal.settings.d/README.txt
• app/wp-config.d/README.txt

When creating a batch of identical sites for training or demonstrations, one may want to create a single source-code-build with several databases/websites running on top (using "Drupal multi-site"). To install extra sites, use the notation "civibuild create buildname/site-id" as in:

## Create the original build
civibuild create training --type drupal-demo --civi-ver 4.5 --url http://demo00.example.org --admin-pass s3cr3t

## Create additional sites (01 - 03)
civibuild create training/01 --url http://demo01.example.org --admin-pass s3cr3t
civibuild create training/02 --url http://demo02.example.org --admin-pass s3cr3t
civibuild create training/03 --url http://demo03.example.org --admin-pass s3cr3t

## Alternatively, create additional sites (01 - 20)
for num in $(seq -w 1 20) ; do
  civibuild create training/${num} --url http://demo${num}.example.org --admin-pass s3cr3t
done
