【git/内源开发】fatal: Out of memory, malloc failed问题的解决

fatal: Out of memory, malloc failed (tried to allocate 3179053026 bytes)

fatal: index-pack failed
主要是由于32位和64位机的不同导致的，用下面的方法可以解决

首先进入该项目的本地git目录，然后执行git config --global pack.XXX = X

如：git config --global pack.windowMemory 1024m

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

[pack]
threads = 1
deltaChaseSize = 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.

执行完上面的步骤之后，执行git repack重新打包

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
