Subject: [PATCH v2 09/11] sparse-checkout: use hashmaps for cone patterns
Date: Thu, 19 Sep 2019 07:43:16 -0700 (PDT)
Message-ID: <95a3285bc6021daa236d98d7e1bbdc5c45fc73b0.1568904188.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.316.v2.git.gitgitgadget@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

The parent and recursive patterns allowed by the "cone mode"
option in sparse-checkout are restrictive enough that we
can avoid using the regex parsing. Everything is based on
prefix matches, so we can use hashsets to store the prefixes
from the sparse-checkout file. When checking a path, we can
strip path entries from the path and check the hashset for
an exact match.

As a test, I created a cone-mode sparse-checkout file for the
Linux repository that actually includes every file. This was
constructed by taking every folder in the Linux repo and creating
the pattern pairs here:

	/$folder/
	!/$folder/*/

This resulted in a sparse-checkout file sith 8,296 patterns.
Running 'git read-tree -mu HEAD' on this file had the following
performance:

	core.sparseCheckout=false: 0.21 s (0.00 s)
	 core.sparseCheckout=true: 3.75 s (3.50 s)
	 core.sparseCheckout=cone: 0.23 s (0.01 s)

The times in parentheses above correspond to the time spent
in the first clear_ce_flags() call, according to the trace2
performance traces.

While this example is contrived, it demonstrates how these
patterns can slow the sparse-checkout feature.
