Subject: refs: support obtaining ref_store for given dir
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cc4dcc855b374d98b664242ee606752dbdcb176b;p=thirdparty%2Fgit.git

refs: support obtaining ref_store for given dir

The refs subsystem uses the `get_main_ref_store()` to obtain the main
ref_store for a given repository. In the upcoming patches we also want
to create a ref_store for any given reference directory, which may exist
in arbitrary paths. For the files backend and the reftable backend, the
reference directory is generally the $GIT_DIR.

To support such behavior, extract out the core logic for creating out
the ref_store from `get_main_ref_store()` into a new function
`get_ref_store_for_dir()` which can provide the ref_store for a
given (repository, directory, reference format) combination.
