Subject: [PATCH v2 07/11] commit-graph: write Bloom filters to commit graph file
Date: Wed, 05 Feb 2020 22:56:26 +0000	[thread overview]
Message-ID: <39ee0610800d7d2d92785d392df941fc5a0b231b.1580943390.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.497.v2.git.1580943390.gitgitgadget@gmail.com>

From: Garima Singh <garima.singh@microsoft.com>

Update the technical documentation for commit-graph-format with the formats for
the Bloom filter index (BIDX) and Bloom filter data (BDAT) chunks. Write the
computed Bloom filters information to the commit graph file using this format.
