问题
I am very new to git and I have been seeing this every once in a while.
For example:
- I work on my branch
branch-A
for few days (branch is created from develop fresh copy) - I do
git add . / git commit -m "blahblah"
to stage and commit my changes - Now I want to get latest changes from remote and merge it into my branch so I ensure I work on latest code
to do so, I do
git checkout develop
to switch to my localdevelop
branch, git status shows I'm behind 37 commitsmyMBPro:MyProj$ git status On branch develop Your branch is behind 'origin/develop' by 37 commits, and can be fast-forwarded. (use "git pull" to update your local branch) Changes not staged for commit: (use "git add/rm <file>..." to update what will be committed) (use "git checkout -- <file>..." to discard changes in working directory)
and the list of deleted, untracked files follow
git fetch origin
, thengit merge origin/develop
while ondevelop
branch shows:
myMBPro:MyProj user$ git fetch origin
myMBPro:MyProj user$ git merge origin/develop
Updating 799c6d7a..510c77ab
Fast-forward
.../Implementations/MyRenderer.cs | 39 ++--
... etc
- I would typically now switch to my branch
branch-A
and dogit merge develop
to merge develop tobranch-A
but I typically do firstgit status
to check all is OK. So, I stay ondevelop
branch and dogit status
- The problem is that I see
git status
reporting probably every single file in my project as changed (some as untracked, some as staged and some as ready to be committed).
```
myMBPro:MyProj user$ git status
On branch develop
Your branch is up to date with 'origin/develop'.
Changes to be committed:
(use "git reset HEAD <file>..." to unstage)
, and the list of files ready to commit, files not staged, and files that are untracked follows after this.
So, I end up with lots of files that I haven't even touched, nor modified, nor added now showing as being somehow modified by me. As a result, I am hesitant to merge them in my branch-A
.
Any idea why is this happening? Is it even normal (but to me it does not sound normal that files I have not changed appear as they are changed by me and now I need to start tracking them, stage and commit them.
I am on MacBookPro, using git from terminal and also using SourceTree
回答1:
Are you sure that you did git commit
immediately before git checkout develop
? The only way that I know this can happen if your working directory is dirty before you checkout develop
and pull
.
Sure, there might be line ending problems, but this still doesn't really explain the issue. An important aspect of git merge
is that it must commit. It is guaranteed to commit if there are no conflicts, and the only way it wont commit is if there are merge conflicts (Which can leave you in that state of variously staged and unstaged files). If you aren't getting merge conflicts (Meaning you see the words fast-forward
), then there seems to be only one possibility:
Say you're working on branch A. Then you commit. Then, you change a couple of files (Or, they are changed automatically by some software you have running at the same time). Then, when you git checkout develop
, you end up copying your index
. The index
being the set of all of the changes you've made since the most recent commit. You can checkout another branch and your index will follow you. This seems to be the only thing, as far as I'm aware, that could cause what you're experiencing. If the merge affects files that part of your index, then the merge will fail. However, it's possible for the merge to succeed if it's a simple fast-forward
that misses your index
, which will cause your index
to be shown on top of the most recent commit.
For the future, try running git status
before git fetch origin; git merge origin/develop
. If you're still running into trouble, you might have to copy-paste what's in your terminal so we can read it.
Also, make sure to only have source code and build scripts in the repo, and to .gitignore
any files that might be created by vim
, your IDE, your build scripts, the running executable, etc. Any of those files are likely going to change constantly.
