git write-tree 写树失败

Question

我正在尝试将分支 feature merge 回 master。 master 在 feature 分支之前有十几个提交，feature 由三个提交组成，与 master 中所做的任何事情都没有冲突 自。这应该是一个非常简单的 merge 。

如果我要执行 rebase 工作流程，则没有任何问题(省略文件名):

$ git checkout feature
$ git rebase master
First, rewinding head to replay your work on top of it...
Applying: first
Applying: second
Applying: third
$ git checkout master
$ git merge feature
Updating 5e42a1d..3642da3
Fast-forward
...
34 files changed, 575 insertions(+), 658 deletions(-)
create mode 100644 ...
create mode 100644 ...
copy ... (64%)
rename ... (64%)
delete mode 100644 DIR_1
create mode 100644 ...
create mode 100644 ...
delete mode 100644 DIR_2
rename ... => A (100%)
rename ... => B (100%)
rename ... => C (100%)
rename ... => D (100%)
rename ... => E (100%)
rename ... => F (100%)
rename ... => G (93%)
rename ... => H (94%)
rename ... => I (95%)
rename ... => J (92%)
rename ... => K (100%)
rename ... => L (100%)
rename ... => M (100%)

但是，如果我进行 merge ，同样应该没有问题:

$ git checkout master
$ git merge feature
Removing DIR_1
Removing DIR_2

...
fatal: git write-tree failed to write a tree

文件 A..J 与 rebase 输出中重命名的文件相同，并且 DIR_1 和 DIR_2 标记为删除模式。

错误是什么意思？当 git rebase/merge 完全成功时，什么会导致我的 git merge 失败？我在 Ubuntu 上使用 git 1.7.0.4。

Answer 1

以防将来有人遇到这个问题，这似乎是一个 git 错误。升级到 1.8.3.1 后，我能够毫无问题地执行 merge :没有预期的冲突，没有“fatal: git write-tree failed to write a tree”。
