Subject: [PATCH 1/3] revision: complicated pathspecs disable filters
Date: Sat, 11 Apr 2020 01:02:59 +0000	[thread overview]
Message-ID: <9cc31c289aa785f026eec84452ed68e80505d95e.1586566981.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.609.git.1586566981.gitgitgadget@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

The changed-path Bloom filters work only when we can compute an
explicit Bloom filter key in advance. When a pathspec is given
that allows case-insensitive checks or wildcard matching, we
must disable the Bloom filter performance checks.

By checking the pathspec in prepare_to_use_bloom_filters(), we
avoid setting up the Bloom filter data and thus revert to the
usual logic.

Before this change, the following tests would fail*:

	t6004-rev-list-path-optim.sh (Tests 6-7)
	t6130-pathspec-noglob.sh (Tests 3-6)
	t6131-pathspec-icase.sh (Tests 3-5)

*These tests would fail when using GIT_TEST_COMMIT_GRAPH and
GIT_TEST_COMMIT_GRAPH_BLOOM_FILTERS except that the latter
environment variable was not set up correctly to write the changed-
path Bloom filters in the test suite. That will be fixed in the
next change.
