Git: Compare All Local Commits to Remote Repo Version

Question

I\'m somewhat new to Git and what I\'m trying to do seems like it should be possible. Basically I\'ve been working off of clone of a repo and have made quite a few local com

Answer 1

The most ready answer is

 git show-branch

What you can do for more control is is use git log annex git rev-list:

 git log --left-right --graph --cherry-pick \
      --oneline branchname...remote/branchname

This is my preferred method and will result in something like

> | fff6bda remote fix
< | c8903ee local fix
< |   724373c Merge branch 'bla' into bla
|\ \  
| < | 2faf547 details
| < | abbdc47 ....
|/ /  
< | befc181 some tagged commit

Include --decorate and you'll get something close to gitk, git-gui and gitweb:

> | fff6bda remote fix
< | c8903ee local fix
< |   724373c (tag_4) Merge branch 'bla' into bla
|\ \  
| < | 2faf547 details
| < | abbdc47 ....
|/ /  
< | befc181 (tag_3) some tagged commit

PRO TIP 1: Use 'git config alias.lr log --long-option1 --long-option2' for convenient use

PRO TIP 2: Use 'git config color.ui auto' for immediate eye-relief

If you wanted all local heads (on all local branches) versus all remote commits (on ditto branches):

git log --decorate --pretty=oneline --all --not --glob=refs/remotes --no-walk

Leave off the no-walk to get all individual revisions. In this case I prefer to use the switches shown earlier (--graph --left-right)

Merges

If you want to see merges clearly, include --boundary

Various advanced queries:

Filtering the results

Git log and rev-list support a whole slew of cunning filtering ability, see the man page

--after '2001-01-01'
--until 'last week'
--author 'martin'
-E -i  --grep='fixes #[0123456789]+'
-S 'new_debug_function'

and many, many others. This should give you plenty of leverage to get exactly at the info you want with almost zero effort

What's stashed locally?

What resides in stashes, but not on remotes (note there is no way to refer to stashes on remote braches because stashes reside in reflogs, and the reflogs (even for remote branches) always reflect local history[1]):

git log $(git rev-list -g stash) --not --glob=refs/remotes 

All (other) unreachable commits...

Notes

• on my workflow these constitue rebased/amended commits and dropped stashes only
• also generating these will take some time depending on the size of your history graph

• this will include any dropped stashes, but not the current stashes

  git log $(git fsck --unreachable --full --lost-found | grep ' commit ' | cut -d' ' -f3) \ --no-walk --not --glob=refs/remotes --oneline --decorate

Scripting

For scripting purposes, replace the use of git log with git rev-list and you'll get just the hashes (and some more script-prrof robustness)
