Description

Add infinite scrolling to the diff viewer.
When working with long diffs, it's common for the diffs to be split up across

several pages. This can end up being a pain to review, as it means having to

deal with manual pagination.
This change replaces the pagination to scroll loading. When user scroll to the

bottom of the page, diffs will be loaded automatically without having to click

anything.
First bind a listening function to the window to check the position. And when

it detect scroll bar touch the bottom, it will active the loading function to

load next diffs. The loading function use ajax to load pagination's diffs, and

append to the current pagination. Similar to the set, when update the diffs,

properties should update one by one.
Remove the pagination and page selection, and modify the description of 'paginate

by' and 'paginate orphans'.

Testing Done

Passed all js-tests.

Manual tests with a 25 diff files review request.
Paginate by 2, and paginate orphans is 10.

When first load the pages, the page loads 2 diffs, and scroll to the bottom, it
loads 2 another difss. At last, the page loads 10 diffs.

Same question as above, is there a reason to set XHR to null?

mingyi March 26, 2015, 10:31 p.m.

Emm.. Because the XHR will still be held after it have accomplish the ajax operation. So set it to null will let gc to collect it. That's what I think~:)

VTL-Developer March 26, 2015, 10:39 p.m.

Not that familiar with javascript GC, but you can do delete variable_name

MI

Explicit seems better. Thanks~:)

You don't actually use attrs anywhere in this function except to feature gate emptying the items table.
If this is a flag, we should be explicit and call it something like dontEmptyTable and explicitly check if it is not true.

mingyi April 1, 2015, 11:24 p.m.

It's a trigger. And the diffViewerPageView and diffFileIndexView will both be trigged. And the attrs are useful in diffViewerPageView, but only a flag in diffFileIndexView, I keep them as the same form. So... I think keep it is a good idea. :)

This logic is kind of hard to grok.

Can we assign the computed window top to a variable and then do the comparison? Also when we break up an if statment we try to have each condition on a single line, e.g.:

if (really_long_condition_one &&
    really_long_condition_two) {
    // ...
}

An artical said js will keep the XHR since it is a long persistent connection. So we should delete it manually.

You're missing a space between that and add.
How about
"Append another set of diffs into the current page."

Wrapping window and document is expensive. We should do that once, in render, storing as this._$window and this._$document, so it'll be faster to handle scrolls.
Another way to improve performance is to listen for resize events and cache the window height and document height there, so tha scrolling doesn't need to recompute each time. That would make this function very fast.
