642998 - Support tabbrowser API removeTab extension

Status: RESOLVED FIXED

(SeaMonkey :: Tabbed Browser, defect)

Description

[[e-mail]]

Firefox's tabbed browser extends removeTab by supporting a parameter object. Currently SeaMonkey uses a boolean flag to disable its undo. We should switch this to a parameter object which will also help us support the animate flag.

I noticed that we don't pass the don't undo flag to session store. This means that we can undo close tab after print preview when we shouldn't be able to.

I wasn't sure what the test was trying to do though, so that might be wrong.

Proposed patch

The test is wrong, because on the moment of writing after hours of debugging a was stupid enough to not see that i'm clearing browser.tabs.max_tabs_undo pref on the wrong place, so i added don't undo param to be sure that sessionstore will restore tab, not our tabbrowser. So we don't need disableUndo here. I don't know the right procedure how to deal with this situation, so r+ if you review (and r+) and add this diff ;)

Attachment: Fixed patch

* Used the fixed test (test passes locally)
* Fixed two tests for blank tabs
  (one to stop them going into undo cache, one is for when you close the last
   tab using the close button; this replaces the tab with a blank tab, and
   undoing that should delete the blank tab.)
