commit a874e28793a8943480449c7fa7bcb9b25311d8b5 Author: Kathy Brade brade@pearlcrescent.com Date: Fri Mar 18 14:20:02 2016 -0400
Bug 13252: Do not store data in the app bundle
When --enable-tor-browser-data-outside-app-dir is enabled, all user data is stored in a directory named TorBrowser-Data which is located next to the application directory.
Display an informative error message if the TorBrowser-Data directory cannot be created due to an "access denied" or a "read only volume" error.
On Mac OS, add support for the --invisible command line option which is used by the meek-http-helper to avoid showing an icon for the helper browser on the dock. --- toolkit/xre/nsAppRunner.cpp | 76 +++++++++++++++--- toolkit/xre/nsXREDirProvider.cpp | 43 +++++----- toolkit/xre/nsXREDirProvider.h | 6 ++ xpcom/io/TorFileUtils.cpp | 142 +++++++++++++++++++++++++++++++++ xpcom/io/TorFileUtils.h | 33 ++++++++ xpcom/io/moz.build | 5 ++ xpcom/io/nsAppFileLocationProvider.cpp | 53 +++++------- 7 files changed, 290 insertions(+), 68 deletions(-)
