My motivation is to reduce the local size of repositories I'm only following, by trimming the history without prejudice to a [N] set of last commits. It feels stupid that the quickest way I'm aware of right now to achieve this is to "git clone --depth N ..." again. filter-branch is ridiculously slow, as it iterates through history. I've tried using graft points, but the combination of: echo [sha] > .git/info/grafts git reflog expire --expire=0 --all git repack -Ad doesn't really save any space and/or reduce the object count as I would expect. It means there's probably still reachable? I'd really love to have a 'git thin [depth]' subcommand to perform the above however. I don't really want to have to iterate through refs just to check if they are still reachable within [n] commits just to delete them. Thanks for any pointer. ``` ## Fredrik Gustafsson, 2014-11-30 12:34 Subject: Re: Thinning a repository Message-ID: <20141130123400.GG31751@paksenarrion.iveqy.com> URL: https://gitlist.dev/e/20141130123400.GG31751%40paksenarrion.iveqy.com In-Reply-To: ``` On Sun, Nov 30, 2014 at 01:18:34PM +0100, Yuri D'Elia wrote: > Is there a quick way to reproduce the effect of a shallow clone on a > local repository that doesn't involve filter-branch and/or re-clone? I'm curious, why is it a bad thing to do a re-clone? If you clone your local repo it would be really fast. -- Med vänlig hälsning Fredrik Gustafsson tel: 0733-608274 e-post: iveqy@iveqy.com ``` ## Yuri D'Elia, 2014-11-30 12:35 Subject: Re: Thinning a repository Message-ID: URL: https://gitlist.dev/e/m5f2up%24554%241%40ger.gmane.org In-Reply-To: <20141130123400.GG31751@paksenarrion.iveqy.com> ``` On 11/30/2014 01:34 PM, Fredrik Gustafsson wrote: > On Sun, Nov 30, 2014 at 01:18:34PM +0100, Yuri D'Elia wrote: >> Is there a quick way to reproduce the effect of a shallow clone on a >> local repository that doesn't involve filter-branch and/or re-clone? > > I'm curious, why is it a bad thing to do a re-clone?

I expect a 'thin' command to be faster by not touching the workspace at all. ```
