[torbutton/master] Bug 19273: Avoid JavaScript patching of the external app helper dialog.

commit 6d5dc7845579ca99d9c46d921876e477ba60935f Author: Kathy Brade <brade(a)pearlcrescent.com> Date: Wed Jun 29 10:33:17 2016 -0400 Bug 19273: Avoid JavaScript patching of the external app helper dialog. Display the external app confirmation dialog in response to the new "external-app-requested" observer service notification. Remove messy overrides of Mozilla components and console log filtering. Remove obsolete "on-modify-drag-list" observer and pre-Firefox 4.0 module registration code from the External App Handler component. --- src/chrome.manifest | 5 +- src/chrome/content/torbutton.js | 93 ----------- src/components/external-app-blocker.js | 295 +++++---------------------------- 3 files changed, 44 insertions(+), 349 deletions(-) diff --git a/src/chrome.manifest b/src/chrome.manifest index e85a205..bb6bcf9 100644 --- a/src/chrome.manifest +++ b/src/chrome.manifest @@ -143,9 +143,7 @@ style chrome://global/content/customizeToolbar.xul chrome://torbutton/skin/torbu # Firefox 4-style component registration component {3da0269f-fc29-4e9e-a678-c3b1cafcf13f} components/external-app-blocker.js -contract @mozilla.org/mime;1 {3da0269f-fc29-4e9e-a678-c3b1cafcf13f} -contract @mozilla.org/uriloader/external-protocol-service;1 {3da0269f-fc29-4e9e-a678-c3b1cafcf13f} -contract @mozilla.org/uriloader/external-helper-app-service;1 {3da0269f-fc29-4e9e-a678-c3b1cafcf13f} +contract @torproject.org/torbutton-extAppBlockerService;1 {3da0269f-fc29-4e9e-a678-c3b1cafcf13f} component {06322def-6fde-4c06-aef6-47ae8e799629} components/startup-observer.js contract @torproject.org/startup-observer;1 {06322def-6fde-4c06-aef6-47ae8e799629} @@ -173,3 +171,4 @@ contract @torproject.org/torRefSpoofer;1 {65be2be0-ceb4-44c2-91a5-9c75c53430bf} category profile-after-change RefSpoofer @torproject.org/torRefSpoofer;1 category profile-after-change StartupObserver @torproject.org/startup-observer;1 category profile-after-change DomainIsolator @torproject.org/domain-isolator;1 +category profile-after-change ExtAppBlockerService @torproject.org/torbutton-extAppBlockerService;1 diff --git a/src/chrome/content/torbutton.js b/src/chrome/content/torbutton.js index 3203cef..5eb26d9 100644 --- a/src/chrome/content/torbutton.js +++ b/src/chrome/content/torbutton.js @@ -3054,104 +3054,12 @@ function torbutton_is_windowed(wind) { return true; } -// This is the console observer used for getting unwanted error messages -// resulting from JS -> C++ transition filtered out. -var torbutton_console_observer = { - - obs : null, - - register: function() { - this.obs = Cc["@mozilla.org/observer-service;1"]. - getService(Ci.nsIObserverService); - this.obs.addObserver(this, "web-console-created", false); - }, - - unregister: function() { - if (this.obs) { - this.obs.removeObserver(this, "web-console-created"); - } - }, - - observe: function(subject, topic, data) { - if (topic === "web-console-created") { - var id = subject.QueryInterface(Ci.nsISupportsString).toString(), - con = HUDService.getHudReferenceById(id); - con.ui.reportPageErrorOld = con.ui.reportPageError; - // Filtering the messages by making them hidden adding the - // "hidden-message" class.
