We'd like to remove nsIFormHistory in-favour of the async FormHistory.jsm. Metro code still uses nsIFormHistory2 - this bug is to replace that usage with the new module.

- For sanitize.js, you just need to port the changes from http://hg.mozilla.org/mozilla-central/diff/0b21e902f7a0/browser/base/content/sanitize.js (also the followup: http://hg.mozilla.org/mozilla-central/rev/96fe69d53f35). (And we really need to unfork these files - Android also has a copy in mobile/android/modules/Sanitizer.jsm that also needs to be fixed in bug 878692 :( ) - Also similar to android, the browser-ui.js reference to nsIFormHistory2 should just removed, since it isn't doing anything useful (form history initialization was refactored in bug 566746, it initializes itself now). - Updating http://hg.mozilla.org/mozilla-central/annotate/8b1bfcf0ce6e/browser/metro/base/tests/mochitest/browser_form_auto_complete.js#l8 to use the FormHistory.jsm API is relatively straightforward, just need to make the same call as in sanitize.js (http://hg.mozilla.org/mozilla-central/annotate/8b1bfcf0ce6e/browser/base/content/sanitize.js#l259)

If any new contributors would like to work on this bug, it should be pretty straightforward. See the links to specific source files in comment 1, and follow the instructions to build and run Metro Firefox here: https://wiki.mozilla.org/Firefox/Windows_8_Integration

Hi, I have started working on this, kindly assign it to me. When I run the metro chrome tests, is it supposed to crash in the end? (I see a crashinjectdll.dll causing this) If this is the case how do I test the changes I made? Eklavya

(In reply to eklavyamirani from comment #5) > When I run the metro chrome tests, is it supposed to crash in the end? (I > see a crashinjectdll.dll causing this) This happens if the tests hang or take too long. (The intentional crash produces a stack track that help diagnose problems in these cases.) There are known problems with running mochitest-metro-chrome in debug builds that might cause this. > If this is the case how do I test the changes I made? Try running the browser_form_auto_complete.js test to see if that one can run without timing out. You may or may not need a non-debug build to make this work. In the top-level directory of your mozilla-central clone: ./mach mochitest-metro browser/metro/base/tests/mochitest/browser_form_auto_complete.js You can also test manually on a page with a simple form to make sure that saving, auto-filling, and clearing of form history is working.

I have tested this (cleared history and added new entries) manually and automatically (using the browser_form_auto_complete.js) and it is working. Kindly review :)

PCOMUtils.defineLazyModuleGetter(this, "PlacesUtils", resource://gre/modules/PlacesUtils.jsm"); This line is also present in browser-scripts.js, so assuming it is loaded in the same window I removed it from sanitize.js as well. Please correct me if I am wrong here. Eklavya
