why git stash cannot abandon the changes made just now?

Question

i forked a project from github, and the origin point to my own github repo, remote point to its original repo, since i want to get update from remote,

i use git pull remote branch_name, then my local repo is in conflict mode, now i want to cancel the effect of git pull, so i use git stash, but was surprised to find i failed to do this? what's wrong?

the detailed info is as follows:

[mirror@home weechat]$ git status
# On branch master
# Unmerged paths:
#   (use "git add/rm <file>..." as appropriate to mark resolution)
#
#       both modified:      CMakeLists.txt
#       both modified:      ChangeLog
#       both modified:      NEWS
#       both modified:      configure.in
#       both modified:      po/cs.po
#       both modified:      po/de.po
#       both modified:      po/es.po
#       both modified:      po/fr.po
#       both modified:      po/hu.po
#       both modified:      po/ru.po
#       both modified:      po/weechat.pot
#       deleted by us:      src/irc/irc-server.c
#       both modified:      weechat.spec
#
no changes added to commit (use "git add" and/or "git commit -a")

fatal: git-write-tree: error building trees
Cannot save the current index state

so how to cannel the effect of git pull? should i delete repo, and download it again?

Solution 1

Run git merge --abort.

You are in the middle of a merge, so stashing is definitely not something you should do (you would lose the history information associated with the merge).

Solution 2

git stash is to save the changes for future use, not for canceling a conflicted state, that's why it doesn't work.

Instead use git reset ORIG_HEAD (see How to undo a git pull?)
