From 9ba83ebfda1137ad7a4d677e6bef57e345288804 Mon Sep 17 00:00:00 2001 From: Tao Klerks Date: Wed, 2 Mar 2022 06:05:24 +0000 Subject: [PATCH] t7063: mtime-mangling instead of delays in untracked cache testing The untracked cache test uses an avoid_racy function to deal with an mtime-resolution challenge in testing: If an untracked cache entry's mtime falls in the same second as the mtime of the index the untracked cache was stored in, then it cannot be trusted. Explicitly delaying tests is a simple effective strategy to avoid these issues, but should be avoided where possible. Switch from a delay-based strategy to instead backdating all file changes using test-tool chmtime, where that is an option, to shave 9 seconds off the test run time. Don't update test cases that delay for other reasons, for now at least (4 seconds).
