About the background, sometimes my project has very huge merge request that it may contains about 900+files 400,000+lines changed. The default diff settings don’t allow me to show all the changed files in changes tab. So i change the datatype of diff_max_patch_bytes in application_settings table into bigint.
Now i success increase the MAX_PATCH_BYTES_UPPER_BOUND setting over original upper limit. But when i create a new merge request, the gitlab return 500 errors.
Following is the error info:
RangeError (integer 10737418240 too big to convert to `int'):

It seems like this param is packaged into CommitDiffRequest and send to Gitaly. In gitaly, the param is set to proto3 int32, so this num is over range.
May i ask how to increase this limit without change the Gitaly source code? Or how to show all 900+ changed files in one merge request?
I would appreciate any help.
