What does "Blame Parent Commit" mean? Thanks!

These are the first 4 characters of the commit id that last added/changed that line of code. Basically the standard abbreviated 8 character SHA1 would take up too much screen real estate. You can still use a 4 character SHA as long as there aren't any commits in your tree that start with the same 4 characters (the possibility of collisions exists with 8 character ones too, it's just less likely). > > What does "Blame Parent Commit" mean? > It means that you have decided that the commit that it currently has selected is not interesting and you want to see the previous commit that modified that section (e.g. it was just some formatting change and you want the commit that actually added the code in question). > Thanks! > > Josh > -- > To unsubscribe from this list: send the line "unsubscribe git" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html ``` ## Jakub Narebski, 2010-10-12 19:50 Subject: Re: Documentation for git gui blame Message-ID: URL: https://gitlist.dev/e/m3iq176vh2.fsf%40localhost.localdomain In-Reply-To: <4CB48C5F.2030007@gmail.com> ``` Chris Packham writes: > On 12/10/10 09:12, Joshua Jensen wrote: > > Is there any documentation for git gui blame > > Not sure but it's displaying the same info as git blame so start with > man git-blame.

Note that there are *two* columns because one column contains plain blame, and second contains blame with code movement and copying detection and discarding changes in whitespace (like "git blame -C -C -w"). So if those columns are different, one column would show commit that put code here, and the other would show commit that changed this code. -- Jakub Narebski Poland ShadeHawk on #git ``` ## Chris Packham, 2010-10-12 21:46 Subject: Re: Documentation for git gui blame Message-ID: <4CB4D748.9040907@gmail.com> URL: https://gitlist.dev/e/4CB4D748.9040907%40gmail.com In-Reply-To: ``` On 12/10/10 12:50, Jakub Narebski wrote: > Chris Packham writes: > >> On 12/10/10 09:12, Joshua Jensen wrote: >>> Is there any documentation for git gui blame >> >> Not sure but it's displaying the same info as git blame so start with >> man git-blame.

Sorry, my bad I should have actually taken a look before responding (and read the question properly). ``` ## Joshua Jensen, 2010-10-13 02:32 Subject: Re: Documentation for git gui blame Message-ID: <4CB51A32.1040304@workspacewhiz.com> URL: https://gitlist.dev/e/4CB51A32.1040304%40workspacewhiz.com In-Reply-To: ``` ----- Original Message ----- From: Jakub Narebski Date: 10/12/2010 1:50 PM > Chris Packham writes: > >> On 12/10/10 09:12, Joshua Jensen wrote: >>> Is there any documentation for git gui blame that explains what the two left columns containing 4 letter SHAs are? >> These are the first 4 characters of the commit id that last >> added/changed that line of code. > Note that there are *two* columns because one column contains plain blame, > and second contains blame with code movement and copying detection and > discarding changes in whitespace (like "git blame -C -C -w").

Thanks, Chris, for the Blame Parent Commit info, too. Josh ```
