From b09b785c785c93d9e26f4fc754116c24ea02bf3c Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Wed, 1 Apr 2020 21:00:44 +0000 Subject: commit-graph: fix buggy --expire-time option The commit-graph builtin has an --expire-time option that takes a datetime using OPT_EXPIRY_DATE(). However, the implementation inside expire_commit_graphs() was treating a non-zero value as a number of seconds to subtract from "now". Update t5323-split-commit-graph.sh to demonstrate the correct value of the --expire-time option by actually creating a crud .graph file with mtime earlier than the expire time. Instead of using a super- early time (1980) we use an explicit, and recent, time. Using test-tool chmtime to create two files on either end of an exact second, we create a test that catches this failure no matter the current time. Using a fixed date is more portable than trying to format a relative date string into the --expiry-date input. I noticed this when inspecting some Scalar repos that had an excess number of commit-graph files. In Scalar, we were using this second interpretation by using "--expire-time=3600" to mean "delete graphs older than one hour ago" to avoid deleting a commit-graph that a foreground process may be trying to load. Also I noticed that the help text was copied from the --max-commits option. Fix that help text.
