How does code hosting work with a staging environment

问题

Up until now, we've all been hosting our mercurial repositories and pulling directly from each other with hg serve. After code is reviewed, QA pushes it to our webdev server, which functions as the staging environment. The (php web) application is tested once again there before it goes to production.

Hg serve is not always reliable (like when the server you want to pull from isnt running!), so we are thinking to switch to code hosting (ie BitBucket). So, we would all have our own accounts there, and the webdev server would have an account as well... But, after QA pushes to the webdev repo, how do the changes make it back to the physical webdev server? Does someone log in to the server to pull them? That doesn't sound right...

The alternative I had is the webdev server repo not being hosted at all, and QA pushing directly to the server with ssh - Is this what people do?

I'm a beginner here, so feel free to correct any wrong assumptions, and I really appreciate your assistance!

Your setup sounds fine. To get the code from your host to your server, you can either

• Periodically poll the repository. Simply running hg pull --update every 10 minutes will work. This is quite cheap since Mercurial will quickly determine when there's nothing new to pull.

• Trigger a pull from the hosting site. Many sites (including Bitbucket) let's you run some action when a changeset is pushed to the site. Bitbucket calls these actions "services".

  They offer integration with many online tools and they also have a generic POST service which you can use. when you enable it, Bitbucket will simply contact a web address of your choice when a changeset is pushed. You should then create a script at that location that will run hg pull --update on your server when the script is invoked.
