See also: Configuration Management for Tiki Projects

The challenge: You have a big Tiki project and you want to use the traditional development, testing, acceptance and production setup (DTAP)

How do you deal with:

• Generic code that will be upstreamed
• Custom code that won't be upstreamed (but should be versioned locally)
• Custom theme/design (which should be versioned locally)
• Content (in database)
  • Content via Wiki Plugins is routinely used to do stuff we used to do in PHP
• Configuration, typically in database, but can be in text files via System Configuration
• Translations that will be upstreamed
• Translations that won't be upstreamed (but should be versioned locally) (could be in DB or lang/xx/custom.php)
• Maintainability of advanced configurations of features

On a related note, here is a Messaging systems evaluation

Examples

• Content evolve in prod (user generated content)
• A new feature is in development, so code needs to be merged from dev to testing. But often preferences and modules need to be configured.
  • If you refresh the testing data from the production server (like as Pre-Dogfood Server, you will loose your preferences & module configurations.

Wishes

• A way to easily check on which server I am (which doesn't get overwritten with rsync)
  • This is to avoid mistakes
• Quick way to compare the configurations between the 2 to 4 sites and have a way to merge data / propagate some data
• Make it possible to identify a site as staging or development and have different settings, such as
  • <meta NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">
  • Don't send out notification emails
  • Site closed

Dev, Test, Prod

• Dev: 10.x
• Test: 9.x latest
• Prod: 9.x older

Before doing svn up on prod, we do svn up on test, and we do a diff of:

• svn diff test
• svn diff prod

Idea

If both sites have shell and use System Configuration, maybe use something like http://www.fossil-scm.org/ to compare/merge...
