However if this is what its gonna take to get what I want, then Im' outta here. Getting a snapshot on the filesystem, in terms of a directory tree (not a reference to, representation of etc etc. but a real life directory tree, files and folders that you can actually interact with - build, edit etc.), of a past version is a basic operation in my book. Even in clearcase this was a cinch. Is there anyone who can see anyway to do this simply, without a script, without creating a branch ? Personally I suspect "$ git checkout ." is what should be doing this (I have confidence in saying this because it seems to want to do this, and does it right at least half the time). But no-one wants to admit to the remotest possibility that it might be off .... In any case, a bunch of smart guys like you should be able to knock this functionality together in hours, if you put your mind to it. I know you guys have put a lot into this project and for many of you it defines who you are - but if you want ppl out there in the user world to take this stuff on, its gotta work for them impassioned plea -----Original Message----- From: Boyd Stephen Smith Jr. [mailto:bss@iguanasuicide.net] Sent: 30 December 2008 22:17 To: Conor Rafferty Cc: git@vger.kernel.org Subject: Re: for newbs = little exercise / tutorial / warmup for windows and other non-sophisticated new Git users :-) [Scanned] On Tuesday 2008 December 30 15:49:22 Boyd Stephen Smith Jr. wrote: > On Tuesday 2008 December 30 15:27:33 you wrote: > > conorr@KINKLADZE /w/GITPLATFORM/swproj $ git status # On branch > > master nothing to commit (working directory clean) > > > > conorr@KINKLADZE /w/GITPLATFORM/swproj $ git checkout versionA . > > > > conorr@KINKLADZE /w/GITPLATFORM/swproj $ ls ABC.txt AC.txt > > > > conorr@KINKLADZE /w/GITPLATFORM/swproj $ rm *.* > > > > conorr@KINKLADZE /w/GITPLATFORM/swproj $ git checkout versionB . > > > > conorr@KINKLADZE /w/GITPLATFORM/swproj $ ls ABC.txt AC.txt BC.txt > > Not a bug. git checkout does not delete files by design. > Try using "git checkout versionB" instead (no paths specified), and it > will properly remove AC.txt from your working tree as well as warning > you that "You're Doing It Wrong" (tm).

Well, there's a lot of things about UNIX and Windows directories that git doesn't store. It'll restore the contents, sure, but not the permissions, timestamps, etc. However git also stores the *history*, if you don't care about that, tarballs or zip archives might actually be a better system for your purposes. But, each time you commit you've made some snapshot (completeness depends on what you staged with git add and friends) and recorded that snapshot as a "later point in time" from the last snapshot you "git checkout"ed. That new object (a "commit") can be identified by it's sha1. It holds a sha1 of all it's parents (also "commits") and of the snapshot alone (a "tree"). You've also figured out how to use lightweight tags to give names (other than their sha1) to your commits. > Is there anyone who can see anyway to do this simply, without a script, > without creating a branch ? Branching is arguably easier than tagging, and probably what you want to do instead. Sure, branches are mutable, but unsigned tags are also fairly mutable. > Personally I suspect "$ git checkout ." is what should be > doing this. I'm pretty sure what you want is "git checkout " not "git checkout ". They operate differently. Modern git can checkout a lightweight tag, but it's going to warn you that it not what you want. > - but if you want ppl out there in the user world to take this stuff on, > its gotta work for them Maybe others do, but I don't really see git as an end-user tool. It's a developer tool and rightly demands a bit of RTFMing before using it effectively. What you seem to *really* want is a bunch of named trees without any relationship between one another. IMHO, git isn't really good at that (but only because it demands to do more). A directory full of tarballs / zip-archives and a couple of scripts you wrote yourself (extract.sh; name-and-save.sh) would probably be better. I admit that there seems to be quite a niche for some sort of trivially usable VCS, but it needs to be good at merging spreadsheets, compressed/binary XML, presentations/decks, and other things not-text, have a pretty GUI, and run securely over TCP/IP ports that no one is willing to block. It will probably be next to useless for doing what git was initially designed for (managing Linux kernel patches). -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/ ``` ## Sitaram Chamarty, 2008-12-31 02:22 Subject: Re: for newbs = little exercise / tutorial / warmup for windows and other non-sophisticated new Git users :-) [Scanned] Message-ID: URL: https://gitlist.dev/e/slrnglllr8.kdq.sitaramc%40sitaramc.homelinux.net In-Reply-To: ``` On 2008-12-30, Conor Rafferty wrote: [re-arranged some of the quotes; it's not in the same order as in your original email...] > Even in clearcase this was a cinch.

You'll have to unlearn this resistance to creating branches. I've never used clearcase, but people tell me it is expensive to create branches and/or merge them later -- almost a project in itself perhaps? In git, however, creating a branch is as cheap as creating a tag, so why not go with the flow until you're a little more familiar with it? > Personally I suspect "$ git checkout ." is what should be leave out the "." is all you needed to do. > doing this (I have confidence in saying this because it seems to want to > do this, and does it right at least half the time). But no-one wants to > admit to the remotest possibility that it might be off .... Because it's not off :-) You're using an unusual construct that is not often used. (I've done path checkout of one or a few files, but not the whole "." ever). So it took people time to analyse what was happening -- such as suggesting you use "git ls-files -s" to see what's in the index at each stage. May I ask where you got the idea that "." is needed? We need to fix that source too ;-) > In any case, a bunch of smart guys like you should be able to knock this > functionality together in hours, if you put your mind to it. > I know you guys have put a lot into this project and for many of you it > defines who you are > - but if you want ppl out there in the user world to take this stuff on, > its gotta work for them While I applaud your efforts to try and understand everything in one long weekend, you'd have more fun if you spaced it out a bit :-) I'll also say that "ppl out there in the user world" will not experiment the way you have -- they'll follow a basic set of commands that work. They'll even (gasp!) use the GUI. Believe me the GUIs are pretty nice, though it won't let you checkout a tag (you can checkout a branch, but not a tag -- because this gets you a detached head which is a little too advanced for normal folks I guess). In other words, you're combining newbie and expert too fast... Finally, I heartily recommend reading the following article: http://thedailywtf.com/Articles/Happy_Merge_Day!.aspx If the hints in the article are not enough for you to figure out this is about clearcase read the comments :-) ```
