Talk:1597: Git

If someone is interested, the best book I've read on it is Pro Git. The chapters 2 and 3 explain pretty well this mess of branching and merging. But it's true that it takes a bit of patience to go over it all. 108.162.228.35 08:47, 30 October 2015 (UTC)

Also take a look at GitFlow: A Successful Git Branching Model. Though Randall is correct there usually comes a time when it is easier to give up and "start again". 162.158.34.147 08:53, 30 October 2015 (UTC)

I never liked the name of this piece of software; in British English, the name "git" is mildly rude :-) https://en.wikipedia.org/wiki/Git_(slang) . Gearóid (talk) 09:20, 30 October 2015 (UTC)

According to word of god it was on purpose: https://en.wikipedia.org/wiki/Git_(software)#History 162.158.22.46 11:41, 30 October 2015 (UTC)

'Internally, Git works by saving the differences between various versions of the files, rather than creating a new copy each time the user "commits" the current version of the code.' - It is exactly the opposite. It stores whole files, or rather all committed pieces of data (blobs). See http://gitready.com/beginner/2009/02/17/how-git-stores-your-data.html 141.101.88.202 09:38, 30 October 2015 (UTC)TK

It is stored as diffs in pack file. Whole file (loose object) are packed automatically by default.

See https://schacon.github.io/gitbook/7_the_packfile.html and https://www.kernel.org/pub/software/scm/git/docs/git-pack-objects.html

Not sure what pack files are used for, but data is stored as is and named by the SHA-1 of its contents. See object model in the same reference. Walenc (talk) 16:02, 30 October 2015 (UTC)

I feel like this article should end with a quick guide to git commands. 108.162.216.27 (talk) (please sign your comments with ~~~~)

Well, I feel this article focuses on explaning git too much that it loses the point of the joke. We have Wikipedia to refer readers to ... The thing is, not just users who are unable to use git beyond a few basic commands, but also those who understand git often use some sort of "start over" method because an action looking perfectly legit got the repository into unusable state, where recovery is much more difficult than reapplying patches. For one of the most common, search for "detached head", for example - especially funny when git insists on falling into that state after checking out master which is in direct contradiction to what docs say when it happens. But I don't feel like rewriting that, sorry :-/ --kavol, 141.101.96.206 16:04, 30 October 2015 (UTC)

I feel you've all been nerd-sniped. 108.162.216.8 19:33, 30 October 2015 (UTC)Pat

The problem is not about the working copy and about the branching tree structure and some git internals that is quite confusing. This 4 years old reddit post can be used as a funny reference: https://www.reddit.com/r/programming/comments/embdf/git_complicated_of_course_not_commits_map_to/

http://tartley.com/?p=1267 "One of the things that tripped me up as a novice user was the way Git handles branches. Unlike more primitive version control systems, git repositories are not linear, they support branching, and are thus best visualised as trees, upon the nodes of which your current commit may add new leaf nodes. To visualise this, it’s simplest to think of the state of your repository as a point in a high-dimensional ‘code-space’, in which branches are represented as n-dimensional membranes, mapping the spatial loci of successive commits onto the projected manifold of each cloned repository." 108.162.210.212 (talk) (please sign your comments with ~~~~)

Should someone mention how git is by default used through a terminal - which is often more confusing than a GUI for most people - and that while there are graphical shells for git, some people refuse to use them because they're not fully-featured? 108.162.221.36 11:43, 30 October 2015 (UTC)

Shit. I use git for almost a year and I delete my repos more often than I'd like to admit. I'm going to read [1] and (hopefully) fix this once and for all. Kripmo (talk) 02:04, 31 October 2015 (UTC)

It was way easier than I thought. This is what I needed: git reset --hard <commit before fuck up>. Its alias will be fu. Kripmo (talk) 08:10, 31 October 2015 (UTC)

The really sad part of all this is that if you work in a multi-dev environment and anyone on the team is doing what Cueball suggests, it negates every other user's ability to use the main trunk properly. Ericm301 (talk) 02:26, 31 October 2015 (UTC)
