version control - Is git not case sensitive?

Question

In the first commitment of my partial called _Electronics it was written beginning with a capital letters, then I changed it to _electronics.

Git under cygwin ignored the case after commiting the new name, so I changed the name by hand in the target repo.

Now it sometimes changes the commited _electronics partial to _Electronics.

What have I done wrong?

Answer 1

It is going to depend on the core.ignorecase configuration value, which is set to false in case-sensitive filesystems and true in msysgit on Windows.

core.ignorecase

If true, this option enables various workarounds to enable git to work better on filesystems that are not case sensitive, like FAT. For example, if a directory listing finds "makefile" when git expects "Makefile", git will assume it is really the same file, and continue to remember it as "Makefile".

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.
