git推出内存不足，malloc失败 [英] git push Out of memory, malloc failed

问题描述

我试图将我的更改远程推送到GitHub，每次 git 由于
$ b

  C：\dev\projects> git push -v 
推送到https：//[e-mail]/mycompany/My-Project.git 
密码对于'github.com'：
 fatal：内存不足，malloc失败（试图分配524288000字节）
致命错误：写入错误：无效参数
  

这非常非常严重。我已经运行了以下命令，升级了 git （这消除了我的设置并导致了很多痛苦，但我离题了）

  git gc --auto --prune = today --aggressive 
 git repack 
  

我甚至碰到了

  http.postbuffer 
  

但最终会再次失败。

这是一个典型的Rails 3.1应用程序，磁盘上的项目总大小为9.69 MB。 我的建议是尝试几个与包相关的git参数：

  [pack] 
 threads = 1 
 deltaCacheSize = 128m 
 windowMemory = 50m 
  

对我来说，最好的结果是设置 git config pack.threads 1 和 git config pack.windowMemory 50m （默认值是10m）。

没有足够的RAM内存（2GB）并保持faili NG。我硬拷贝回购，并将其移动到另一台具有更多内存（8GB）的机器上。它变得更好，但仍然失败。

最后，我下载了最新版本的git（ https://github.com/git/git ），编译并安装它。通过使用相同的参数运行 git repack -adf 来解决问题。之后，我运行 git gc --aggressive --prune = now

本地机器我把它推到主，覆盖远程仓库， git push -f origin master 。为避免将来发生类似的错误，请不要将不必要的大文件添加到回购站（在我的情况下，我获得了3.5GB的SQL转储:)）并禁用增量压缩大文件（如图像，PDF，视频）。将以下几行添加到 .gitattributes ：

  *。pdf -delta 
 * .jpg -delta 
  

I am trying to push my changes remotely to GitHub, every so often git fails due to

C:\dev\projects>git push -v
Pushing to https://[e-mail]/mycompany/My-Project.git
Password for 'github.com':
fatal: Out of memory, malloc failed (tried to allocate 524288000 bytes)
fatal: write error: Invalid argument

This is very, very aggravating. I have run the following commands, upgraded git (which wiped out my settings and caused lots of pain, but I digress)

git gc --auto --prune=today --aggressive
git repack

I have even bumped the value of

http.postbuffer

but eventually it will fail again.

This is a typical Rails 3.1 application, total project size on disk is 9.69 MB.

解决方案

My advice is to try several git parameters related with pack:

[pack]
   threads = 1
   deltaCacheSize = 128m
   windowMemory = 50m

What it got better results for me was setting git config pack.threads 1 and git config pack.windowMemory 50m (default is 10m).

Still, my host didn't have enough RAM memory (2GB) and kept failing. I hard copied the repo and moved it to another machine with more RAM (8GB). It got better but still failed.

Finally, I downloaded the latest version of git (https://github.com/git/git), compile it and install it. That fixed the problem just by running git repack -adf with the same parameters. After that I run git gc --aggressive --prune=now

Once I got the repo fixed in my local machine I pushed it to master, overwriting the remote repo, git push -f origin master.

To prevent similar errors in the future try not to add unnecessary large files to the repo (in my case I got a SQL dump of 3.5GB :)) and disable delta compression for large files (such as images, PDFs, videos). Add the following lines to .gitattributes:

*.pdf -delta
*.jpg -delta
