Fix Bug 936492, implement tree selector for multi tree support

[ghost]

@erikrose r?

[erikrose]

I can no longer click the search field to focus it. It immediately defocuses.

[ghost]

oops, fixing.

The Switch Tree menu is missing on results pages. There, it should run the same search against any tree you select.

It does appear in file views, but selecting a different tree takes you to a browse view of the root of the tree. It should take you to a parallel file in the new tree, if one exists. (Otherwise, the browse-the-root behavior is correct.)

You will likely need some back-end support for all of this. I am happy to contribute.

The first case should be fine. The second however, there will definitely have to be some backend logic and your contribution will be much appreciated.

[erikrose]

Remember, the search template is used only when someone actually hits Return. So the search selector still doesn't show up for any live searches.

[erikrose]

Also, we need to preserve the checked state of the Case Sensitive checkbox when we choose a new tree from a search-results page.

[erikrose]

Remember to leave space for tree descriptions in the dropdowns. You can put placeholder text there for now.

Awesome, thanks for all of the feedback. I will continue on this one first thing in the morning and we can sync up when you are online.

If you can make the tree selector menu items on files and directory views link to /some_tree/parallel/what/ever/dir/or/file, I can write a "parallel" controller on the backend that redirects to a parallel dir or file if there is one (and otherwise to the root).

[erikrose]

When I'm at http://33.33.33.77:8000/code2/source/main.c, the tree menu item points to /code/parallel/. It should point to /code/parallel/main.c.

[erikrose]

And I suppose the currently selected item shouldn't even be a link.

[ghost]

On number one, I know why that is happening and on number 2, we can do that, let me look.

[erikrose]

Parallel links look good!

• The switcher menu on search-results pages has no tree descriptions.
• The currently selected tree is still a link.

[erikrose]

r+. Let's merge that baby in!

[erikrose]

I added https://bugzilla.mozilla.org/show_bug.cgi?id=951462 for backend support for the tree descriptions.
