From 8b9b0f3af73233595b6b1103ffb30242508a5e47 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 8 Feb 2006 21:49:47 -0800 Subject: [PATCH] "Assume unchanged" git: do not set CE_VALID with --refresh When working with automatic assume-unchanged mode using core.ignorestat, setting CE_VALID after --refresh makes things more cumbersome to use. Consider this scenario: (1) the working tree is on a filesystem with slow lstat(2). The user sets core.ignorestat = true. (2) "git checkout" to switch to a different branch (or initial checkout) updates all paths and the index starts out with "all clean". (3) The user knows she wants to edit certain paths. She uses update-index --no-assume-unchanged (we could call it --edit; the name is inmaterial) to mark these paths and starts editing. (4) After editing half of the paths marked to be edited, she runs "git status". This runs "update-index --refresh" to reduce the false hits from diff-files. (5) Now the other half of the paths, since she has not changed them, are found to match the index, and CE_VALID is set on them again. For this reason, this commit makes update-index --refresh not to set CE_VALID even after the path without CE_VALID are verified to be up to date. The user still can run --really-refresh to force lstat() to match the index entries to the reality.
