git question

git question

[Jean-Christophe Helary]

Sorry for the beginner level for this question.

When I do a git pull and I get, for ex:

 etc/NEWS       |  6 ++++++
 lisp/info.el   |  4 ++--
 lisp/server.el | 10 ++++++----

like I just had.

What git command should I use to examine what are the modifications on the three above files?

(better to ask this on help-gnu-emacs)

Click on the file to open.

To show version control related keys, type

  C-x v C-h 

and that suggests typing

  C-x v l

if you then click on a commit line and type d, 
you should see a color highlighted diff listing

Why ?

I'm on the command line. I can't click on a file.

> To show version control related keys, type

I'm asking for a git command from the command line.
If you mean there are none please say so.

I have the following in my ~/.gitconfig

[alias]
        ll = log -p --reverse @{1}..

I usually execute a "git ll" just after any "git pull" I do

$ git diff HEAD@{1}

shows the difference between HEAD and the previous state of HEAD.

So when I do
 git diff HEAD@{2}

I get the result vs the state of HEAD 2 "git pull" before on my machine, right ?

Depends on what you did inbetween.  See git-reflog(1).

Excellent. Thank you !

" For example, HEAD@{2} means "where HEAD used to be two moves ago",
       master@{one.week.ago} means "where master used to point to one week ago in this local
       repository", and so on. See gitrevisions(7) for more details. "

That was new to me -- thanks! Just for completeness' sake, the explicit
(non-relative) way of doing this would be to look at the top of the
fast-forward message and use the updated-from commit as an anchor:

Normally you would first do a “git fetch”, then see the diff between
current state and the remote branch, and only then decide if you want
to merge that:

$ git fetch
$ git diff HEAD..origin/master
$ git merge origin/master

(substitute a different remote branch name as necessary).

But if you did a blind pull already, you can look back this way:

$ git diff HEAD@{1}..

:) I trust the commiters to only commit proper code. I'm just curious about some files sometimes.
But thank you for the hint !

Thank you, and thank you Andreas for the same reply.

Now, if I want to only check 1 file out of the multiple files that have been commited ?

Just add it to the command line.

Note the subtle difference: “git diff HEAD@{1}..” will give the diff
between previous and current states, while “git diff HEAD@{1}” will
give the same diff but in reverse.

Thank you for the notice. The difference had escaped me.

No, they are both the same (unless your working tree is in modified
state).

You mean ..HEAD@{1} will give the reverse diffs, right?

git question

[Rasmus]

Hi,

Re commit acabacaa5689f0644a47edae7c66bbdd68418194

    http://orgmode.org/cgit.cgi/org-mode.git/commit/?id=acabacaa5689f0644a47edae7c66bbdd68418194

This should probably have gone to maint as it is a bugfix.  For some
reason I pushed the commit to master.

Could I now use git cherry-pick to add it maint?  Or is there a better
way?  Or is it better to just let it live on master and only be part of
the next major Org version?

Thanks,
Rasmus

I haven't tried this, but wouldn't that work:

- Cherry pick that commit into maint
- Merge maint into master

My guess is that the second step will result in just a Merge commit in
master, with just commit hash updates. But then the merge pointers between
master and maint will also be synced.

 Or

is it better to just let it live on master and only be part of

Yep, git cherry-pick should be used in these situations.
