How to find out in which commit a particular code was added?
GitGit CommitGit Problem Overview
I want to find out in which commit did I add the code given below:
if (getListView().getChildCount() == 0)
getActivity().findViewById(android.R.id.empty).setVisibility(View.VISIBLE);
How do I achieve this?
Git Solutions
Solution 1 - Git
git log -S searchTerm
gives you the commits in which the search term was introduced.
Solution 2 - Git
Run git blame on the file. It'll show you the commit ID, the date and time, and who committed it- for each line. Then just copy out the commit identifier and you can use it in git log <commit> or git show <commit>.
For example, I've got a file, called test.txt, with lines added on different commits:
$ cat test.txt
First line.
Second line.
Running the git blame:
$ git blame test.txt
^410c3dd (Leigh 2013-11-09 12:00:00 1) First line.
2365eb7d (Leigh 2013-11-09 12:00:10 2) Second line.
The first bit is the commit ID, then name, then date, time, time zone, and finally the line number and line contents.
Solution 3 - Git
There is something quicker than issuing a blame on the full file. If the line is ${lineno} and the file is ${filename} you can:
git blame -L ${lineno},${lineno} ${filename}
Example:
git blame -L 2,2 test.txt
Solution 4 - Git
git log -S "mention here line of code" [file-path]
For example:
git log -S "First line" test.txt
Providing the file name with its path is obvious because, most of the time, we want to know who introduced a particular code segment in a particular file.
Solution 5 - Git
If code is being maintained in Git repository and intellij IDE along with Git plugin is being used to browse the code then i have found the following way very intuitive:
- Open the file in
intellij - Go to context menu -> Git -> Annotate.
- New window will appear where each line in new window tells who made that line commit.
