Subject: [PATCH v4 4/8] t7300: add testcase showing unnecessary traversal into ignored directory
Date: Tue, 11 May 2021 18:34:04 +0000 [thread overview]
Message-ID: <317abab3571e69394cf0a0dbe971440bca16964b.1620758049.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1020.v4.git.git.1620758049.gitgitgadget@gmail.com>
From: Elijah Newren <newren@gmail.com>
The PNPM package manager is apparently creating deeply nested (but
ignored) directory structures; traversing them is costly
performance-wise, unnecessary, and in some cases is even throwing
warnings/errors because the paths are too long to handle on various
platforms. Add a testcase that checks for such unnecessary directory
traversal.
