This article describes how to use the Mercurial version control system on A2 Hosting servers.
The Python-based Mercurial version control system is installed on all A2 Hosting shared servers. Like other version control systems, Mercurial enables you to track multiple revisions of files and directories.
To create a Mercurial repository, all you have to do is log in to your A2 Hosting account using SSH, and then type the following command:
hg init REPOSITORY
Replace REPOSITORY with the name of the directory where you want to create the repository (if the directory does not already exist, the hg init command creates it).
You can publish your Mercurial repositories and make them available to others on the web. To do this, follow these steps:
Copy the following text and paste it into the file you just created:
#!/usr/bin/env python # # An example hgweb CGI script, edit as necessary # See also http://mercurial.selenic.com/wiki/PublishingRepositories # Path to repo or hgweb config to serve (see 'hg help hgweb') config = "/home/USERNAME/REPOSITORY" # Uncomment and adjust if Mercurial is not installed system-wide: #import sys; sys.path.insert(0, "/path/to/python/lib") # Uncomment to send python tracebacks to the browser if an error occurs: #import cgitb; cgitb.enable() from mercurial import demandimport; demandimport.enable() from mercurial.hgweb import hgweb, wsgicgi application = hgweb(config) wsgicgi.launch(application)
At the command prompt, type the following command. Replace FILENAME with the name of the file that you created in step 3:
chmod 755 FILENAME
The repository is now accessible on the web at the URL http://www.example.com/cgi-bin/FILENAME, where example.com represents your domain name, and FILENAME represents the name of the file you created in step 3. For example, to clone this repository, you would type the following command:
hg clone http://www.example.com/cgi-bin/FILENAME
