What is the difference from drop in the Git interactive rebase and just deleting the line of the commit?
回答1:
There is no difference by default; it's just another way to say the same thing.
But, if you set rebase.missingCommitsCheck to warn or error, then removing a line will trigger a warning (useful for detecting a messed-up cut-and-paste).
Then setting the line to drop explicitly tells Git that you want to drop that commit, and no warning is shown for it.
回答2:
There is in fact another small difference:
You can explicitly "drop" all commits. The effect will be the same as a reset.
However if you just delete all lines, then git will tell you "Nothing to do".
Usually you would not use rebase anyway in that case. I learned the difference only when I tried to explain removing a commit with rebase to a co-worker using a dummy commit.
回答3:
Marking a commit as drop is the same as deleting the line.
The commit will be dropped/ignored.
See when you scroll down:
If you remove a line here THAT COMMIT WILL BE LOST.
The drop command was added in 2.6.0-rc1:
"git rebase -i" learned "drop commit-object-name subject" command as another way to skip replaying of a commit.
