运行 interactive rebase 时我之前的提交是哪一个？

Question

当我运行类似 git rebase -i --rebase-merges eeb1425e0 我的提交列表显示颠倒，即第一个提交是最后一个，最后一个提交是第一个：

pick A Penultimate commit
pick B Penult commmit
pick C Latest commit

# Rebase eeb1425e..5a3f045b onto eeb1425e (288 commands)
#
# Commands:
# p, pick <commit> = use commit
# r, reword <commit> = use commit, but edit the commit message
# e, edit <commit> = use commit, but stop for amending
# s, squash <commit> = use commit, but meld into previous commit
# f, fixup <commit> = like "squash", but discard this commit's log message
# x, exec <command> = run command (the rest of the line) using shell
# b, break = stop here (continue rebase later with 'git rebase --continue')
# d, drop <commit> = remove commit
# l, label <label> = label current HEAD with a name
# t, reset <label> = reset HEAD to a label
# m, merge [-C <commit> | -c <commit>] <label> [# <oneline>]
# .       create a merge commit using the original merge commit's
# .       message (or the oneline, if no original merge commit was
# .       specified). Use -c <commit> to reword the commit message.
#
# These lines can be re-ordered; they are executed from top to bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.
#
# However, if you remove everything, the rebase will be aborted.
#
# Note that empty commits are commented out

然后，当压缩选项显示 squash = use commit, but meld into previous commit 时，我按下 squash 如下：

pick A Penultimate commit
squash B Penult commmit
pick C Latest commit

B 的上一次提交是 A 还是 C？ B 是 merged/squashed 还是 A 还是 C？

Answer 1

提交顺序确实与您通常使用 git log 看到的顺序相反，因此：

pick A Penultimate commit
pick B Penult commmit
pick C Latest commit

如果将第二行更改为 squash，Git 将：

cherry-pick 提交 A 到 begin 进行新的提交，但尚未完成；
在实际进行新提交之前将提交 B 压缩到其中；和
cherry-pick 提交 C 进行第二次新提交；

给你我喜欢画的图画，如：

          A--B--C   [abandoned]
         /
...--o--o--AB--C'   <-- branch-name

这里的 A-B-C 链是原来的三个提交，最后一个画在右边（而不是顶部或底部），新的 AB-C' 链是两个新的提交，再次与右侧绘制的最后一个。您的分支名称用于标识提交 C，现在标识新副本 C'.

旁注：倒数第三个词是 antepenultimate。例如，"Penultimate" 字面意思是 "second from last". If there is a fourth from last you need to identify, this is the preantepenultimate. There appears to be no English-language word for "fifth from last". Following links here arrives at propreantepenultimate, but see the status at the Collins dictionary。

另一个旁注：interactive rebase 愿意进行提交然后取消提交，因此上面的描述 ("squash before actually making commit") 只是 shorthand 您将 看到的 当您查看结果时，而不是对底层机制的完整描述。实际的提交集可能包括额外放弃的临时提交。 Git 最终会自行清理所有这些。
