Summary:
This is really rough and needs work (particularly, there's some diff code I
really need to refactor since I sort-of-copy-pasted it) but basically
functional.
Show text changes between diffs and allow users to revert to earlier versions.
Differential's line-oriented diff style isn't ideal for large blocks of text but
I'm betting this is probably good enough in most cases. We can see how bad it is
in practice and then fix it if needbe.
I added a bunch of support for "description" but didn't add the feature in this
diff, I'll either follow up or task it out since it should be a pretty
straightforward change.
Test Plan: Looked at history for several Phriction documents, clicked "previous
change" / "next change", clicked revert buttons.

Summary:
Add the differential parse cache to the GC. This is the largest object in the
system by a wide margin, I think.
This table is potentially gigantic which is why the script truncates it before
doing a schema change.
Test Plan: Ran the GC daemon, it cleaned up some parse caches.

Summary: These came up in dealing with the diff produced by T271. When a file is
unmodified, don't try to use the "ignore all whitespace" algorithm on it. Also,
detect "changed only by adding or removing trailing whitespace" vs "this file
was not modified" correctly.
Test Plan: Viewed the diff that came out of running 'arc diff' on my T271 mess.

Summary:
Differential uses a byte-oriented linewrap algorithm. Instead, use a
character-oriented one which will handle utf-8 properly.
This implies a very slightly performance hit but we only run this code for lines
which need to wrap, and the results get cached. It took about ~2.5ms for the
test file on my machine. I'll keep an eye on it but I think it's currently a
manageable cost.
Test Plan:
Diffed this file: https://secure.phabricator.com/P43
...and got it to render like this:
https://secure.phabricator.com/file/info/PHID-FILE-331ac241bede705b193b/
To do so, I had to disable the un-utf8 block which we can't actually do yet
because of intraline diff, but it shows that once we can get rid of that it
works completely correctly. It will "sort of" work in the meantime (nothing
terrible happens).

Summary:
Diffs with missing context don't render properly in the "ignore all whitespace"
algorith, so don't try to use it. These diffs can occur if someone creates a
diff via the web interface, for example, or if they muck around in their copy of
'arc'.
See D473, T246 (a problem with D473), rPe5bb756b5191720 (revert of D473) and
T231.

Viewed a diff with missing context from the web interface. Verified normal diffs
still rendered with all whitespace ignored.

See comments. I think this will fix the issue, where we end up handling off
garbage to htmlspecialchars() after highlighting a file we've stuck full of \0
bytes.
The right fix for this is to make wordwrap and intraline-diff utf8 aware and
throw this whole thing away. I'll work on that but I think this fixes the
immediate issue.

Summary:
If you "chmod +x" a file and then generate a diff and click "show 20 lines" on
that diff, you get another janky copy of the property table. Render the property
table only for top-level rendering requests.
This started happening after D409, which fixed the far-more-obvious bug of these
things never showing up. We must have changed the logic at some point since this
side effect was surprising to me. :P
Test Plan:
Created a diff with changes and +x, clicked "show 20 lines".
- Original diff had file property header table thing, showing the +x.
- New context brought in by "show 20 lines" didn't have it anymore.

Summary:
Separates changeset IDs from rendering. Now each changeset has a "rendering
reference" which is basically a description of what the ajax endpoint should
render. For Differential, it's in the form "id/vs". For Diffusion,
"branch/path;commit".
I believe this fixes pretty much all of the bugs related to "show more" breaking
in various obscure ways, although I never got a great repro for T153.
Test Plan:
Clicked "show more" in diffusion change and commit views and differential diff,
diff-of-diff, standalone-diff, standalone-diff-of-diff views. Verified refs and
'whitespace' were always sent correctly.

Summary:
This is a followup to D228. Basically, we use "changeset" (and, implicitly,
changesetID) for way too much stuff now.
One thing it can't possibly capture is the complete, arbitrary mapping between
the left and right sides of the displayed diff and the places we want to store
the left and right side comments. This causes a bunch of bugs; basically adding
inline comments is completely broken in diff-of-diff views prior to this patch.
Make this mapping explicit.
Note that the renderer already passes this mapping to
DifferentialChangesetParser which is why there are no changes outside this file,
I just didn't finish the implementation during the port.
This has the nice side-effect of fixing T132 and several other bugs.
Test Plan:
Made new-file and old-file comments on a normal diff; reloaded page, verified
comments didn't do anything crazy.
Expanded text on a normal diff, made new-file and old-file comments; reloaded
page, verified comments.
Repeated these steps for a previous diff in the same revision; verified
comments.
Loaded diff-of-diffs and verified expected comments appeared. Made new left and
right hand side comments, which almost work, see below.
NOTE: There is still a bug where comments made in the left-display-side of a
diff-of-diffs will incorrectly be written to the right-storage-side of the
right-display-side diff. However, this is an issue with the JS (the PHP is
correct) so I want to pull it out of scope for this patch since I think I need
to fix some other JS stuff too and this improves the overall state of the world
even if not everything is fixed.

Summary:
DifferentialChangesetParser currently takes the Changeset object to mean a bunch
of different and mutually conflicting things implicitly:
- Changeset ID is used to access the render cache.
- Changeset ID is also used to tell the ajax endpoint what to render when
clicking "show more".
- Changeset object has the actual changes.
- Changeset ID and "oldChangesetID" are used to choose where to show inline
comments and how to attach new ones.
This indirectly causes a bunch of problems, like T141 and T132. Move toward
making all these separate things explicit. I want to have the changeset object
only mean the actual changes to display.
Test Plan:
Looked at changesets and verified the render cache was accessed correctly (and
not accessed in other cases).

(which are formatted properly due to being in non-ws-ignoring mode) and
uses them to replace the text in the ws-ignoring diff.
