Summary:
Ref T13519. This is a little fuzzy, but I think the workflow here is:
- View an intradiff, generating an ephemeral comparison changeset with no changeset ID. This produces a state key of "*".
- Apply "hidden" state changes to the changeset.
- View some other intradiff and/or diff view.
- The code attempts to use "*" as a changset ID?
I'm not entirely sure this is accurate; this was observed in production and I couldn't get a clean reproduction case locally.
Optimistically, try making changeset IDs explicit rather than relying on state keys to be "usually changeset-ID-like".
Test Plan: Used "hidden" locally across multiple intradiffs, but I wasn't cleanly able to reproduce the initial issue.

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.

Ref T13515. Currently, opening a file to a particular line in an external editor relies on replacing "%l" with "%l" (which is escaped as "%25l") on the server, and then replacing "%25l" with the line number on the client. This will fail if the file path (or any other variable) contains "%l" in its unencoded form.
The parser also can't identify invalid variables.
Pull the parser out, formalize it, and make it generate an intermediate representation which can be sent to the client and reconstituted.
(This temporarily breaks Diffusion and permanently removes the weird, ancient integration in Dark Console.)

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:
Ref T13501. The older ngram code has some "prefix" behavior that tries to handle cases where a user issues a very short (one or two character) query.
This code doesn't work, presumably never worked, and can not be made to work (or, at least, I don't see a way, and am fairly sure one does not exist).
If the user searches for "xy", we can find trigrams in the form "xy*" using the index, but not in the form "*xy". The code makes a misguided effort to look for " xy", but this will only find "xy" in words that begin with "xy", like "xylophone".
For example, searching Files for "om" does not currently find "random.txt".
Remove this behavior. Without engaging the trigram index, these queries fall back to an unidexed "LIKE" table scan, but that's about the best we can do.

Since almost all rules are lower-priority than these link rules, this behavior isn't obvious. However, two rules have broadly higher priority (monospaced text, and one variation of link rules has higher priority than the other), and the latter can be used to perform an XSS attack with input in the general form `()[ [[ ... | ... ]] ]` so that the inner link rule is evaluated first, then the outer link rule uses non-flat text in an unsafe way.

Summary: Depends on D20779. Ref T13403. Bad parameters may cause this call to fail without setting an error code; if it does, catch the issue and go down the normal connection error pathway.
Test Plan:
- With "mysql.port" set to "quack", ran `bin/storage probe`.
- Before: wild mess of warnings as the code continued below and failed when trying to interact with the connection.
- After: clean connection failure with a useful error message.

Summary:
Fixes T13336.
- Prevent `--no-indexes` from being combined with `--for-replica`, since combining these options can only lead to heartbreak.
- In `--for-replica` mode, dump caches too. See discussion in T13336. It is probably "safe" to not dump these today, but fragile and not correct.
- Mark the "MarkupCache" table as having "Cache" persistence, not "Data" persistence (no need to back it up, since it can be fully regenerated from other datasources).
Test Plan: Ran `bin/storage dump` with various combinations of flags.

Summary:
Fixes T13390. We have some old code which doesn't dynamically select between "utf8mb4" and "utf8". This can lead to dumping utf8mb4 data over a utf8 connection in `bin/storage dump`, which possibly corrupts some emoji/whales.
Instead, prefer "utf8mb4" if it's available.
Test Plan: Ran `bin/storage dump` and `bin/storage shell`, saw sub-commands select utf8mb4 as the client charset.

Summary:
Ref T13386. If you issue `differential.query` with a large offset (like 3000), it can overheat regardless of policy filtering and fail with a nonsensical error message.
This is because the overheating limit is based only on the query limit, not on the offset.
For example, querying for "limit = 100" will never examine more than 1,100 rows, so a query with "limit = 100, offset = 3000" will always fail (provided there are at least that many revisions).
Not all numbers work like you might expect them to becuase there's also a 1024-row fetch window, but basically small limits plus big offsets always fail.
Test Plan: Artificially reduced the internal window size from 1024 to 5, then ran `differential.query` with `offset=50` and `limit=3`. Before: overheated with weird error message. After: clean result.
