commit 38e31a62d48dd8ea8bee02673b7050338fc1c22a Author: Kathy Brade <brade@pearlcrescent.com> Date: Mon Feb 29 16:55:06 2016 -0500 fixup! Bug #4234: Use the Firefox Update Process for Tor Browser. When built with --enable-tor-browser-data-outside-app-dir, account for the new Mac OS directory structure (see bug #13252). Many of the updater changes we made earlier are no longer needed. Also, fix a JS warning inside toolkit/mozapps/update/nsUpdateService.js and improve startup time logging of update status. --- config/createprecomplete.py | 4 ++ toolkit/mozapps/update/nsUpdateService.js | 3 +- toolkit/mozapps/update/updater/updater.cpp | 18 ++++-- toolkit/xre/nsUpdateDriver.cpp | 36 +++++++++++- toolkit/xre/nsXREDirProvider.cpp | 14 +++++ tools/update-packaging/common.sh | 4 ++ tools/update-packaging/make_full_update.sh | 21 +++++-- tools/update-packaging/make_incremental_update.sh | 71 ++++++++++++++--------- 8 files changed, 128 insertions(+), 43 deletions(-) diff --git a/config/createprecomplete.py b/config/createprecomplete.py index 48cba96..be571be 100644 --- a/config/createprecomplete.py +++ b/config/createprecomplete.py @@ -10,6 +10,10 @@ import sys import os +# TODO When TOR_BROWSER_DATA_OUTSIDE_APP_DIR is used on all platforms, +# we should remove all lines in this file that contain: +# TorBrowser/Data + def get_build_entries(root_path): """ Iterates through the root_path, creating a list for each file and directory.
