[rbm/master] Bug 25435: use --no-auto-check-trustdb to avoid modifying gpg keyring files

commit db41d8e754ed8cd6cee7bca18d76d59f8f7f369b Author: Nicolas Vigier <boklm(a)torproject.org> Date: Tue Mar 6 21:27:39 2018 +0100 Bug 25435: use --no-auto-check-trustdb to avoid modifying gpg keyring files By default gpg will from time to time update its trust database. When this happens it will also modify the keyring files to add some trust information. To avoid this we add the --no-auto-check-trustdb option. As we don't use the Web of Trust when we use a keyring file, we also disable it using `--trust-model always`. --- lib/RBM/DefaultConfig.pm | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/lib/RBM/DefaultConfig.pm b/lib/RBM/DefaultConfig.pm index 4121264..d758b8e 100644 --- a/lib/RBM/DefaultConfig.pm +++ b/lib/RBM/DefaultConfig.pm @@ -216,7 +216,8 @@ OPT_END export LC_ALL=C [% IF c('gpg_keyring'); - SET gpg_kr = '--keyring ' _ path(c('gpg_keyring'), path(c('gpg_keyring_dir'))) _ ' --no-default-keyring'; + SET gpg_kr = '--keyring ' _ path(c('gpg_keyring'), path(c('gpg_keyring_dir'))) + _ ' --no-default-keyring --no-auto-check-trustdb --trust-model always'; END; -%] exec [% c('gpg_bin') %] [% c('gpg_args') %] --with-fingerprint [% gpg_kr %] "\$@"

[tor-launcher/master] Bug 23136: Moat integration (fetch bridges for the user)

commit e921bb15681ac54c9e937b564d31a2a6ec2ceb33 Author: Kathy Brade <brade(a)pearlcrescent.com> Date: Wed Feb 14 10:07:45 2018 -0500 Bug 23136: Moat integration (fetch bridges for the user) Modify the setup wizard and Network Settings window to allow automated retrieval of bridges using Moat, a BridgeDB service which works over a meek transport and requires the user to solve a CAPTCHA to obtain bridges. The new tl-bridgedb.jsm JavaScript module handles all communication with BridgeDB, and it functions by starting a copy of meek-client-torbrowser and operating as a PT client parent process (see https://gitweb.torproject.org/torspec.git/tree/pt-spec.txt) This feature can be disabled (and the Moat-related Tor Launcher UI hidden) by setting the pref extensions.torlauncher.moat_service to an empty string. --- src/chrome/content/network-settings-overlay.xul | 60 +- src/chrome/content/network-settings-wizard.xul | 9 +- src/chrome/content/network-settings.js | 630 +++++++++++++++++++- src/chrome/content/network-settings.xul | 7 +- src/chrome/locale/en/network-settings.dtd | 4 + src/chrome/locale/en/torlauncher.properties | 14 + src/chrome/skin/activity.svg | 17 + src/chrome/skin/network-settings.css | 84 ++- src/chrome/skin/reload.svg | 6 + src/defaults/preferences/prefs.js | 6 + src/modules/tl-bridgedb.jsm | 746 ++++++++++++++++++++++++ src/modules/tl-util.jsm | 57 +- 12 files changed, 1583 insertions(+), 57 deletions(-) diff --git a/src/chrome/content/network-settings-overlay.xul b/src/chrome/content/network-settings-overlay.xul index b49dbab..3d42c15 100644 --- a/src/chrome/content/network-settings-overlay.xul +++ b/src/chrome/content/network-settings-overlay.xul @@ -1,6 +1,6 @@ <?xml version="1.0"?>  @@ -93,11 +93,11 @@ oncommand="toggleElemUI(this);"/> <groupbox id="bridgeSpecificSettings"> <hbox align="end" pack="end"> -

[tor-browser/tor-browser-52.6.0esr-8.0-2] Bug 1370027: Part 1 - Cleanly handle a subprocess child being reaped by NSPR. r=aswan

commit f7e0d580f4159357cfa3dc69cb9ed4d9027e9b9f Author: Kris Maglione <maglione.k(a)gmail.com> Date: Tue Jun 6 16:00:53 2017 -0700 Bug 1370027: Part 1 - Cleanly handle a subprocess child being reaped by NSPR. r=aswan The first time any other code in the parent process uses NSPR (usually via nsIProcess) to spawn a new process, it spawns a thread to contuously wait for any child process to exit. This thread winds up reaping our child processes before we get the chance to wait for them, which leads us to continuously poll for them to exit. We don't have a good way to handle this, but checking the error status of waitpid at least prevents us from failing catastrophically.
