commit affde91732fccc6b61113a64f05278d087705a38 Author: Kathy Brade brade@pearlcrescent.com AuthorDate: 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 | 56 +++++++++++++++++--- toolkit/xre/nsXREDirProvider.cpp | 23 +++++++- toolkit/xre/nsXREDirProvider.h | 6 +++ xpcom/io/TorFileUtils.cpp | 96 ++++++++++++++++++++++++++++++++++ xpcom/io/TorFileUtils.h | 32 ++++++++++++ xpcom/io/moz.build | 5 ++ xpcom/io/nsAppFileLocationProvider.cpp | 13 ++++- 7 files changed, 223 insertions(+), 8 deletions(-)
