Windows上的Git，“内存不足-malloc失败”

Question

遇到了存储库问题，并尝试了几乎所有可能的配置设置，例如。pack.WindowMemory等我相信有人已经将一个大文件检入到远程存储库中，现在每次我尝试将其拉入或推入时，GIT都会尝试将其打包并耗尽内存：Auto packing the repository for optimum performance. You may alsorun "git gc" manually. See "git help gc" for more information.Counting objects: 6279, done.Compressing objects: 100% (6147/6147), done.fatal: Out of memory, malloc failed (tried to allocate 1549040327 bytes)error: failed to run repack尝试了git gc和git repack的各种选项，但始终返回相同的错误。几乎放弃了，即将创建一个新的仓库，但我想先问一下:)

Answer 1

我在这里找到了对我有用的解决方案。

在.git / config文件（客户端和/或服务器）中，我添加了以下内容：

[core]

  packedGitLimit = 128m

  packedGitWindowSize = 128m

[pack]

  deltaCacheSize = 128m

  packSizeLimit = 128m

  windowMemory = 128m

Answer 2

自git-v2.5.0 （2015年8月）以来，git-for-windows（以前为MSysGit）

      提供了Pan.student注意到的64位版本。       在此答案中，我建议安装Cygwin 64位（提供64位Git版本）。

达到4GB的限制时，我Out of memory, malloc failed使用MSysGit遇到了类似的问题：

> git --version

git version 1.8.3.msysgit.0

> file path/Git/cmd/git

path/Git/cmd/git: PE32 executable for MS Windows (console) Intel 80386 32-bit

> time git clone --bare -v ssh://linuxhost/path/repo.git

Cloning into bare repository 'repo.git'...

MSysGit达到4 GB屏障后崩溃

最后来自Cygwin的 git 64位修复了它：

> git --version

git version 1.7.9

> file /usr/bin/git

/usr/bin/git: PE32+ executable (console) x86-64 (stripped to external PDB), for MS Windows

> time git clone --bare -v ssh://linuxhost/path/repo.git

来自Cygwin的git 64位成功

仅供参考linuxhost：64位：

repo.git> git config -l

user.email=[e-mail]

core.repositoryformatversion=0

core.filemode=true

core.bare=true

repo.git> git --version

git version 1.8.3.4

repo.git> uname -a
