Get up to speed on Git for tracking, branching, merging, and managing code revisions. Through a series of step-by-step tutorials, this practical guide takes you quickly from Git fundamentals to advanced techniques, and provides friendly yet rigorous advice for navigating the many functions of this open source version control system.

This thoroughly revised edition also includes tips for manipulating trees, extended coverage of the reflog and stash, and a complete introduction to the GitHub repository. Git lets you manage code development in a virtually endless variety of ways, once you understand how to harness the system’s flexibility. This book shows you how.

  • Learn how to use Git for several real-world development scenarios
  • Gain insight into Git’s common-use cases, initial tasks, and basic functions
  • Use the system for both centralized and distributed version control
  • Learn how to manage merges, conflicts, patches, and diffs
  • Apply advanced techniques such as rebasing, hooks, and ways to handle submodules
  • Interact with Subversion (SVN) repositories—including SVN to Git conversions
  • Navigate, use, and contribute to open source projects though GitHub

Subversion colleagues to adopt the one-line summary voluntarily. After all, a one- line summary is helpful in any version control system. • There’s an extra line in each commit message, prefixed with git-svn-id. git svn uses this line to keep track of where the commit came from. In this case, the commit came from, as of revision 33142, and the server unique ID is the same one used to generate Hyrum’s fake email address. • git svn created a new.

File. Once you stage a changed file, the next git diff no longer yields diff output for that file. In this way, you can step progressively through each dirty file in 108 | Chapter 8: Diffs your working directory until the differences disappear, meaning that all files are staged in your index. Don’t forget to check for new or deleted files, too. At any time during the staging process, the command git diff --cached shows the complementary changes, or those changes already staged in the index.

Change sets for entire “modules.” Furthermore, CVS introduced a new paradigm for the lock. Whereas earlier systems required a developer to lock each file before changing it and thus forced one developer to wait for another in serial fashion, CVS gave each developer write permission in his private working copy. Thus, changes by different developers could be merged auto- matically by CVS unless two developers tried to change the same line. In that case, the conflict was flagged and the.

Commits, use git checkout -b my_branch to create a new, local branch on which to develop your changes. Referencing Other Repositories To coordinate your repository with another repository, you define a remote. A re- mote is a named entity stored in the config file of a repository. It consists of two different parts. The first part of a remote states the name of the other repository in the form of a URL. The second part, called a refspec, specifies how a ref (which usually represents a.

Trick supported by git-daemon. The following example entry allows a server to provide multiple, virtually hosted Git daemons: # Place on one long line in /etc/inetd.conf git stream tcp nowait nobody /usr/bin/git-daemon git-daemon --inetd --verbose --export-all --interpolated-path=/pub/%H%D In the command shown, git-daemon will fill in the %H with a fully qualified host name and %D with the repository’s directory path. Because %H can be a logical host name, different sets of repositories.
