Windows 上的 Git，“内存不足 - malloc 失败”

Git on Windows, "Out of memory - malloc failed"

提问by timothyclifford

Have run into a problem with repository and tried almost every possible config setting found out there eg. pack.WindowMemory etc etc

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

I believe someone has checked in a large file to remote repository and now each time I try and pull or push to it, GIT tries to pack it and runs out of memory:

我相信有人已经将一个大文件签入到远程存储库，现在每次我尝试拉取或推送到它时，GIT 都会尝试打包它并耗尽内存：

Auto packing the repository for optimum performance. You may also
run "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

Have tried git gc& git repackwith various options but keeps returning same error.

尝试了git gc和git repack各种选项，但一直返回相同的错误。

Almost given up and about to just create a new repo but thought I'd ask around first :)

几乎放弃了，准备创建一个新的仓库，但我想我会先问一下:)

I found a solution Herethat worked for me.

我在这里找到了一个对我有用的解决方案。

In .git/config file (client and/or server) I added the following:

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

For reference (you might already seen it), the msysgit case dealing with that issue is the ticket 292.

作为参考（您可能已经看过），处理该问题的 msysgit 案例是票证 292。

It suggests several workarounds:

它提出了几种解决方法：

• Disable delta compression globally. For this you have to set pack.windowto 0. Of course this will make the repository much larger on disc.
• Disable delta compression for some files. Check the deltaflag on the manpage to gitattributes.
• git config --global pack.threads 1
• git config --global pack.windowMemory 256m(you already tried that one, but also illustrated in "Error when pulling warning: suboptimal pack - out of memory")
• other settings are mentioned in "git push fatal: unable to create thread: Resource temporarily unavailable" and "Git pull fails with bad pack header error" in case this is pack-related.
• sm4adds in the comments:

• 全局禁用增量压缩。为此，您必须设置pack.window为 0。当然，这将使光盘上的存储库更大。
• 对某些文件禁用增量压缩。检查联机帮助页delta上的标志以gitattributes.
• git config --global pack.threads 1
• git config --global pack.windowMemory 256m（您已经尝试过那个，但也在“拉出警告时出错：次优包 - 内存不足”中说明）
• “ git push 致命：无法创建线程：资源暂时不可用”和“ Git pull 失败，包头错误错误”中提到了其他设置，以防与此pack相关。
• sm4在评论中添加：

To disable the delta compression for certain files, in .git/info/attributes, add:

要禁用某些文件的增量压缩，请在.git/info/attributes中添加：

*.zip binary -delta

From Gitattributes man page:

从Gitattributes 手册页：

Delta compression will not be attempted for blobs for paths with the attribute deltaset to false.

对于属性delta设置为 false 的路径，不会尝试对 blob 进行增量压缩。

Maybe a simpler workaround would be to somehow reset the history before that large file commit, and redo the other commits from there.

也许更简单的解决方法是在大文件提交之前以某种方式重置历史记录，并从那里重做其他提交。

I got a similar Out of memory, malloc failedissue using MSysGitwhen reaching the 4GB barrier:

达到 4GB 时，我在Out of memory, malloc failed使用MSysGit时遇到了类似的问题：

Finally git 64 bits from Cygwinfix it:

最后来自Cygwin 的git 64 位修复它：

This worked for me, but I had to set the options via the command line using:

这对我有用，但我必须使用以下命令通过命令行设置选项：
