POGit: Remove commits which only changes a timestamp
text
Body
copied!<p>I'm looking for a proper solution to remove only-timestamp-changes in the history of my repository .</p> <p>If you wonder what I'm doing here: I'm trying to build a git repository based on downloaded nightly zip archives of a piece of software where every day all files were timestamped with the date.. but weren't actually changed. In order to keep the actual changes, I want to get rid of these changes.</p> <p>I have already played with filter-branch to remove sub directories. Has someone an idea how to achieve this?</p> <p>Some additional points I have:</p> <ol> <li>I know that the change is always in a specific line (if I walk from top to bottom, I could remove a change of one file if only this line was touched?)</li> <li>The old and new timestamp is -- for one commit -- in all files the same. </li> <li>The line is globally unique, I'd say it's even timeless unique.</li> </ol> <p><strong>Appending</strong></p> <p><strong>Question 1: How do I know which files are actually changed?</strong></p> <p>Okay, I give two examples. The first one contains actually a change, the second one only the stamping.</p> <p>In my examples, the timestamp is always in line 5. My targets are to remove the one line changed in <em>commit A</em> and to eliminate <em>commit B</em>.</p> <p>Example Commit A (Before)</p> <pre><code>a file with a header a file with a header a file with a header /* Build date: 2013-24-05 11:01:01 (02129bb861061d1a052c592e2dc6b383) */ other stuff other stuff something before the change other stuff </code></pre> <p>Example Commit A (After)</p> <pre><code>a file with a header a file with a header a file with a header /* Build date: 2013-25-05 11:01:01 (57cec4137b614c87cb4e24a3d003a3e0) */ other stuff other stuff something after the change other stuff </code></pre> <p>Example Commit B (Before)</p> <pre><code>a file with a header a file with a header a file with a header /* Build date: 2013-24-05 11:01:01 (02129bb861061d1a052c592e2dc6b383) */ other stuff other stuff something which is not altered other stuff </code></pre> <p>Example Commit B (After)</p> <pre><code>a file with a header a file with a header a file with a header /* Build date: 2013-25-05 11:01:01 (57cec4137b614c87cb4e24a3d003a3e0) */ other stuff other stuff something which is not altered other stuff </code></pre>
