Summary:
Ref T13513. This is mostly an infrastructure cleanup change.
In a perfect world, this would be a series of several changes, but they're tightly interconnected and don't have an obvious clean, nontrivial partition (or, at least, I don't see one). Followup changes will exercise this code repeatedly and all of these individual mutations are "obviously good", so I'm not too worried about the breadth of this change.
---
Inline comments are stored as transaction comments in the `PhabricatorAuditTransactionComment` and `DifferentialTransactionComment` classes.
On top of these two storage classes sit `PhabricatorAuditInlineComment` and `DifferentialInlineComment`. Historically, these were an indirection layer over significantly different storage classes, but nowadays both storage classes look pretty similar and most of the logic is actually the same. Prior to this change, these two classes were about 80% copy/pastes of one another.
Part of the reason they're so copy/pastey is that they implement a parent `Interface`. They are the only classes which implement this interface, and the interface does not provide any correctness guarantees (the storage objects are not actually constrained by it).
To simplify this:
- Make `PhabricatorInlineCommentInterface` an abstract base class instead.
- Lift as much code out of the `Audit` and `Differential` subclasses as possible.
- Delete methods which no longer have callers, or have only trivial callers.
---
Inline comments have two `View` rendering classes, `DetailView` and `EditView`. They share very little code.
Partly, this is because `EditView` does not take an `$inline` object. Historically, it needed to be able to operate on inlines that did not have an ID yet, and even further back in history this was probably just an outgrowth of a simple `<form />`.
These classes can be significantly simplified by passing an `$inline` to the `EditView`, instead of individually setting all the properties on the `View` itself. This allows the `DetailView` and `EditView` classes to share a lot of code.
The `EditView` can not fully render its content. Move the content rendering code into the view.
---
Prior to this change, some operations need to work on inlines that don't have an inline ID yet (we assign an ID the first time you "Save" a comment). Since "editing" comments will now be saved, we can instead create a row immediately.
This means that all the inline code can always rely on having a valid ID to work with, even if that ID corresponds to an empty, draft, "isEditing" comment. This simplifies more code in `EditView` and allows the "create" and "reply" code to be merged in `PhabricatorInlineCommentController`.
---
Client-side inline events are currently handled through a mixture of `ChangesetList` listeners (good) and ad-hoc row-level listeners (less good). In particular, the "save", "cancel", and "undo" events are row-level. All other events are list-level.
Move all events to list-level. This is supported by all inlines now having an ID at all stages of their lifecycle.
This allows some of the client behavior to be simplified. It currently depends on binding complex ad-hoc dictionaries into event handlers in `_drawRows()`, but it seems like almost all of this code can be removed. In fact, no more than one row ever seems to be drawn, so this code can probably be simplified further.
---
Finally, save an "isEditing" state. When we rebuild a revision on the client, click the "edit" button if it's in this state. This is a little hacky, but simpler to get into a stable state, since the row layout of an inline depends on a "view row" followed by an "edit row".
Test Plan:
- Created comments on either side of a diff.
- Edited a comment, reloaded, saw edit stick.
- Saved comments, reloaded, saw save stick.
- Edited a comment, typed text, cancelled, "unedited" to get state back.
- Created a comment, typed text, cancelled, "unedited" to get state back.
- Deleted a comment, "undeleted" to get state back.
Weirdness / known issues:
- Drafts don't autosave yet.
- Fixed in D21187:
- When you create an empty comment then reload, you get an empty editor. This is a bit silly.
- "Cancel" does not save state, but should, once drafts autosave.
- Mostly fixed in D21188:
- "Editing" comments aren't handled specially by the overall submission flow.
- "Editing" comments submitted in that state try to edit themselves again on load, which doesn't work.

At some point, the highlighting behavior for the timeline broke. When you follow a link to a particular timeline story, the story should be highlighted.
Prior to this change, the `<a />` tag itself highlights, but there's no associated CSS and it's too deep in the tree to do anything useful.

Summary:
Ref T13455. Update the other "view state" properties to work like "highlight" now works.
Some complexity here arises from these concerns:
- In "View Standalone", we render the changeset inline. This is useful for debugging/development, and desirable to retain.
- In all other cases, we render the changeset with AJAX.
So the client needs to be able to learn about the "state" properties of the changeset on two different flows. Prior to this change, each pathway had a fair amount of unique code.
Then, some bookkeeping issues:
- At inital rendering time, we may not know which renderer will be selected: it may be based on the client viewport dimensions.
- Prior to this change, the client didn't separate "value of the property for the changeset as rendered" and "desired value of the property".
Test Plan:
- Viewed changes in Differential, Diffusion, and in standalone mode.
- Toggled renderer, character sets, and document engine (this one isn't terribly useful). Reloaded, saw them stick.

Summary:
See <https://discourse.phabricator-community.org/t/storage-upgrade-error/3748>.
It is broadly unsafe for migrations to use "save()". If the object gains new fields later, the query will include "SET newField = X", which will fail against the old schema which is in the process of being upgraded.
Instead, migrations must issue raw SQL against the schema as it is expected to exist at the time the migration executes.
Migrations have followed this rule for a long time, but this ~6 year old migration was overlooked. Update it to issue a raw query to perform the policy update.
Test Plan: This is somewhat flimsy since rebuilding a genuine reproduction case is messy, but used "bin/storage --apply ..." to at least get the new query to execute against modern Phabricator without issues.

Fixes T5028. Older versions of Git (apparently, from before 2010) did not provide a way to extract the raw body of a commit message from "git log", so we approximate it with "subject" and "wrapped body".
In newer versions of Git, the raw body can be extracted exactly.
Adjust how we extract messages based on the version of Git, and try to be more faithful to edge cases: particularly, be more careful to extract the correct number of trailing newlines.
Test Plan:
- Added "var_dump()" + "die(1)" later in this method, then pushed various commit messages. Used "&& false" to force execution down the old path (either path should work in modern Git).
- Observed more faithful extraction of messages, including a more faithful extraction of the number of trailing newlines. Extraction is fully faithful if we can go down the "%B" path, which we should be able to in nearly all modern cases.
- Not all messages extract faithfully or consistently across the old and new versions, but the old extraction is destructive so this is likely about as close as we can realistically ever get.
