[tor-launcher/master] Bug 23136: Moat integration (fetch bridges for the user)
by gk＠torproject.org 02 Mar '18

02 Mar '18

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"> - <radiogroup id="bridgeTypeRadioGroup" flex="1" style="margin: 0px" - oncommand="onBridgeTypeRadioChange()"> - <hbox align="center"> + <radiogroup id="bridgeTypeRadioGroup" flex="1" style="margin: 0px"> + <hbox class="bridgeRadioContainer"> <radio id="bridgeRadioDefault" - label="&torsettings.useBridges.default;" selected="true"/> + label="&torsettings.useBridges.default;" selected="true" + oncommand="onBridgeTypeRadioChange()"/> <button class="helpButton" oncommand="onOpenHelp('bridgeHelpContent')"/> <spacer style="width: 3em"/> @@ -108,8 +108,24 @@ <spring/> </hbox> - <radio align="start" id="bridgeRadioCustom" - label="&torsettings.useBridges.custom;"/> + <vbox id="bridgeDBSettings"> + <hbox class="bridgeRadioContainer"> + <radio id="bridgeRadioBridgeDB" + label="&torsettings.useBridges.bridgeDB;" + oncommand="onBridgeTypeRadioChange()"/> + </hbox> + <vbox id="bridgeDBContainer" align="start"> + <description id="bridgeDBResult"/> + <button id="bridgeDBRequestButton" + oncommand="onOpenBridgeDBRequestPrompt()"/> + </vbox> + </vbox> + + <hbox class="bridgeRadioContainer"> + <radio align="start" id="bridgeRadioCustom" + label="&torsettings.useBridges.custom;" + oncommand="onBridgeTypeRadioChange()"/> + </hbox> </radiogroup> </hbox> <vbox id="bridgeCustomEntry"> @@ -153,6 +169,36 @@ </hbox> </vbox> + <vbox id="bridgeDBRequestOverlayContent" align="center"> + <vbox> + <label id="bridgeDBPrompt"/> + <image id="bridgeDBCaptchaImage"/> + <hbox> + <spacer id="bridgeDBReloadSpacer"/> + <spacer flex="1"/> + <textbox id="bridgeDBCaptchaSolution" size="35" + placeholder="&torsettings.useBridges.captchaSolution.placeholder;" + oninput="onCaptchaSolutionChange()"/> + <spacer flex="1"/> + <deck id="bridgeDBReloadDeck"> + <button id="bridgeDBReloadCaptchaButton" + tooltiptext="&torsettings.useBridges.reloadCaptcha.tooltip;" + oncommand="onReloadCaptcha()"/> + <image id="bridgeDBNetworkActivity"/> + </deck> + </hbox> + <label id="bridgeDBCaptchaError"/> + <separator/> + <hbox pack="center"> + <button id="bridgeDBCancelButton" + oncommand="onCancelBridgeDBRequestPrompt()"/> + <button id="bridgeDBSubmitButton" disabled="true" + label="&torsettings.useBridges.captchaSubmit;" + oncommand="onCaptchaSolutionSubmit()"/> + </hbox> + </vbox> + </vbox> + <vbox id="errorOverlayContent"> <hbox pack="center"> <description errorElemId="message" flex="1"/> diff --git a/src/chrome/content/network-settings-wizard.xul b/src/chrome/content/network-settings-wizard.xul index 86c2e01..00145a8 100644 --- a/src/chrome/content/network-settings-wizard.xul +++ b/src/chrome/content/network-settings-wizard.xul @@ -1,6 +1,6 @@ <?xml version="1.0"?>  @@ -33,7 +33,6 @@ <image class="tbb-logo"/> </hbox> - <separator class="tall"/> <vbox class="firstResponses" align="center"> <label>&torSettings.connectPrompt;</label> <label>&torSettings.configurePrompt;</label> @@ -52,11 +51,13 @@ torShowNavButtons="true"> <stack flex="1"> <vbox> - <separator class="tall"/> <vbox id="bridgeSettings"/> - <separator/> <vbox id="proxySettings"/> </vbox> + <vbox id="bridgeDBRequestOverlay" class="messagePanel" pack="center" + hidden="true"> + <vbox id="bridgeDBRequestOverlayContent"/> + </vbox> <vbox id="configErrorOverlay" class="messagePanel" pack="center" hidden="true"> <vbox id="errorOverlayContent"/> diff --git a/src/chrome/content/network-settings.js b/src/chrome/content/network-settings.js index 773a647..dc3c9ab 100644 --- a/src/chrome/content/network-settings.js +++ b/src/chrome/content/network-settings.js @@ -1,4 +1,4 @@ -// Copyright (c) 2017, The Tor Project, Inc. +// Copyright (c) 2018, The Tor Project, Inc. // See LICENSE for licensing information. // // vim: set sw=2 sts=2 ts=8 et syntax=javascript: @@ -8,12 +8,15 @@ const Cc = Components.classes;
