The reasons for core.ignoreCase true

[kingma-sbw]

In https://git-scm.com/docs/git-config/2.14.6#Documentation/git-config.txt-coreignoreCase I read "to enable Git to work better on file-systems that are not case sensitive". On Windows the most used file system is NTFS which is case sensitive.

The problem arises when committing to a repository that is CICD ed to a case sensitive OS like Linux. All web-servers and browser distinguish case. For web development this setting on true (the default on a Windows installation) is problematic.

Why specifically that version of the docs? 2.14.6 is 6 years old at this point? That section is unchanged since 2018, but I'm still curious.

I read "to enable Git to work better on file-systems that are not case sensitive".

Ok.

true

which is case sensitive.

Yes, but for all intents and purposes usually no. The documentation could probably distinguish between properly case-insensitive filesystems and NTFS being case sensitive, but usually operating case insensitively.

The problem arises when committing to a repository that is CICD ed to a case sensitive OS like Linux.

Please explain what you mean by that. what is "CICDed to" supposed to mean?
"deployed to"? "CI tested on"?

All web-servers and browser distinguish case.

I'm pretty sure IIS doesn't always distinguish case, but wether we're talking "all" or "most" probably doesn't matter. Anyways, how is this related to git?

For web development this setting on true (the default on a Windows installation) is problematic.

Elaborate how. Please also consider that Git does detect case sensitiveness when initializing (or cloning) a repo and sets core.ignorecase accordingly and the linked docs say as much:

Internal variable which enables various workarounds to enable Git to work better on filesystems that are not case sensitive, like APFS, HFS+, FAT, NTFS, etc. […]

The default is false, except git-clone[1] or git-init[1] will probe and set core.ignoreCase true if appropriate when the repository is created.
