From 06f1ae9aaca969ee95ef840f22b6b461c304542d Mon Sep 17 00:00:00 2001 From: Samuel Huang Date: Tue, 13 Mar 2018 18:19:34 +0000 Subject: [Zucchini] Move Zucchini from /chrome/installer/ to /components/. (Use "git log --follow" to see older revisions of files). /components/ is the most logical place to put Zucchini, which only depends on /base and /testing/gtest. This move also enables Zucchini to be used by the Component Updater. Details: - Move all files; run the following to change deps and guards: sed 's/chrome\/installer/components/' *.cc *.h -i sed 's/CHROME_INSTALLER/COMPONENTS/' *.cc *.h -i - Sorting works out pretty well! - Change all 'chrome/installer/zucchini' to 'components/zucchini' throughout other parts of the repo; sort if necessary. - Fix 6 'git cl lint' errors. - Change 1 Bind() usage to BindRepeated(). - Update OWNER.
