Subject: [PATCH v3] submodule: suppress checking for file name and ref ambiguity for object ids
Date: Sun, 06 Sep 2020 20:47:39 +0000	[thread overview]
Message-ID: <pull.725.v3.git.1599425259773.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.725.v2.git.1599370473141.gitgitgadget@gmail.com>

From: Orgad Shaneh <orgads@gmail.com>

The argv argument of collect_changed_submodules() contains obly object ids
(the objects references of all the refs).

Notify setup_revisions() that the input is not filenames by passing
assume_dashdash, so it can avoid redundant stat for each ref.

Also suppress refname_ambiguity flag to avoid filesystem lookups for
each object. Similar logic can be found in cat-file, pack-objects and more.

    submodule: suppress checking for file name and ref ambiguity for object
    ids
    
    The argv argument of collect_changed_submodules() contains obly object
    ids (submodule references).
    
    Notify setup_revisions() that the input is not filenames by passing
    assume_dashdash, so it can avoid redundant stat for each ref.
    
    A better improvement would be to pass oid_array instead of stringified
    argv, but that will require a larger change, which can be done later.
