Max File Size for LFS Files?

[hillin]

Issue

Impacted version: 4.11

Deployment mode: standalone app on a Windows Server 2016 machine, intranet access via a 1Gbps wired network

Problem description:
LFS files over 30,000,000 bytes cannot be pushed.

I've created a dummy file (1fb535...) of size 30,000,001 bytes, running

GIT_TRACE=1 git lfs push --object-id origin 1fb535...

gives a 404 error while PUTting (see the log attached at the end of this issue, too long). However, if this file is one byte shorter, it can be pushed successfully.

Is there a place I could config the max file size?

After a hard searching, I figured out it's IIS who did the trick. All requests are filtered and rejected if its content length is over 30,000,000 bytes by default.
For anyone who also come into this issue, you can change the Maximum allowed content length in IIS as explained in this documentation.

@hillin please extend this https://github.com/gitbucket/gitbucket/wiki/Installation-on-IIS-and-Helicontech-Zoo wiki page with this info.

[hillin]

@aadrian I've updated the wiki page.

[aadrian]

@hillin thanks. I suppose other webservers might also have default values that prevent "unlimited" upload/download :) .

[hillin]

@aadrian yes, that's totally reasonable. But what surprised me is, although gitbucket is running as a standalone program on my server (started directly with java.exe), it is still under control of IIS.

@hillin Thanks for updating Wiki 👍
