My excuses aside from laziness are doing it this way will let us see if anyone complains, we can always do a migration later if people do complain, and there's likely to be a lot of garbage data for older / bigger installs, and the migration didn't seem worth itgiven it would also likely be expensive in these cases.
Test Plan: made a draft inline comment on DX and observed DX had a note icon on Differential home page. made a draft comment on DX and observed DX had a note icon on Differential home page. deleted a draft inline comment and noted icon disappeared from Differential homepage. Submitted a draft comment + inline comment and noted icon disappeared.

Summary:
Ref T2222. This is the big one.
This migrates each `DifferentialComment` to one or more ApplicationTransactions (action, cc, reviewers, update, comment, inlines), and makes `DifferentialComment` a double-reader for ApplicationTransactions.
The migration is pretty straightforward:
- If a comment took an action not otherwise covered, it gets an "action" transaction. This is something like "epriestley abandoned this revision.".
- If a comment updated the diff, it gets an "updated diff" transaction. Very old transactions of this type may not have a diff ID (probably only at Facebook).
- If a comment added or removed reviewers, it gets a "changed reviewers" transaction.
- If a comment added CCs, it gets a "subscribers" transaction.
- If a comment added comment text, it gets a "comment" transaction.
- For each inline attached to a comment, we generate an "inline" transaction.
Most comments generate a small number of transactions, but a few generate a significant number.
At HEAD, the code is basically already doing this, so comments in the last day or two already obey these rules, roughly, and will all generate only one transaction (except inlines).
Because we've already preallocated PHIDs in the comment text table, we only need to write to the transaction table.
NOTE: This significantly degrades Differential, making inline comments pretty much useless (they each get their own transaction, and don't show line numbers or files). The data is all fine, but the UI is garbage now. This needs to be fixed before we can deploy this to users, but it's easily separable since it's all just display code.
Specifically, they look like this:
{F112270}
Test Plan:
I've migrated locally and put things through their paces, but it's hard to catch sketchy stuff locally because most of my test data is nonsense and bad migrations wouldn't necessarily look out of place.
IMPORTANT: I'm planning to push this to a branch and then shift production over to the branch, and run it for a day or two before bringing it to master.
I generally feel good about this change: it's not that big since we were able to separate a lot of pieces out of it, and it's pretty straightforward. That said, it's still one of the most scary/dangerous changes we've ever made.

Summary:
Ref T2222. Currently, `DifferentialComment` stores both (a) the text of comments and (b) various other transaction details. This data needs to map to both Transactions and TransactionComments in the long run. This diff separates out all the data which is bound for the TransactionComment table, so that when we migrate `DifferentialComment` itself it will //only// need to migrate into the Transactions table. This is a much simpler migration than the inline comment one was, partly because it set up infrastructure and partly because the data is less complex.
Basically, I'm just proxying the read/write for the comment text into the other table. All readers already go through the Query class, and there are only three writers (preview, comment, implicit comment on diff update) which are all highly regular and straightforward to test.
We can also back out of this diff very easily: doing double writes cost only one line of code (`$this->content = $content;`) so we have proper double writes and a trivial revert path.
Test Plan:
- Without migrating, added comments and saw them show up.
- Migrated.
- Saw all the old comments, and no damage to the new ones.

Currently, "Closed" and "Abandoned" are treated as "closed". I want to add a flag which treats "Accepted" as "Closed", too, for Asana and other companies who use an Asana-like workflow.
The background here is that their workflow is a bit weird. They basically do audits, but have a lot of things which Diffusion doesn't do well right now. This one change makes Differential fit their workflow fairly well, even though it's an audit workflow.
To prepare for this, normalize the definition of "closed" better. We have a few callsites which explicitly check for "ABANDONED || CLOSED", and normalizing this is cleaner anyway.
Also delete the very old COMMITTED status, which has been obsolete for over a year.

Fixes T4109. If a revision has a bad `repositoryPHID` (for example, because the repository was deleted), `DifferentialRevisionQuery` calls `didRejectResult()` on it, which raises a policy exception, even if the viewer is omnipotent. This aborts the `MessageParser`, because it does not expect policy exceptions to be raised for an omnipotent viewer.
Fix this in two ways:
# Never raise a policy exception for an omnipotent viewer. I think this is the expected behavior and a reasonable rule.
# In this case, load the revision for an omnipotent viewer.
This feels a little gross, but it's the only place where we do this in the codebase right now. We can clean this up later on once it's more clear what the circumstances of checks like these are.

Summary:
While we mostly have reasonable effective object accessibility when you lock a user out of an application, it's primarily enforced at the controller level. Users can still, e.g., load the handles of objects they can't actually see. Instead, lock the queries to the applications so that you can, e.g., never load a revision if you don't have access to Differential.
This has several parts:
- For PolicyAware queries, provide an application class name method.
- If the query specifies a class name and the user doesn't have permission to use it, fail the entire query unconditionally.
- For handles, simplify query construction and count all the PHIDs as "restricted" so we get a UI full of "restricted" instead of "unknown" handles.
Test Plan:
- Added a unit test to verify I got all the class names right.
- Browsed around, logged in/out as a normal user with public policies on and off.
- Browsed around, logged in/out as a restricted user with public policies on and off. With restrictions, saw all traces of restricted apps removed or restricted.

Summary:
Ref T2222. This implements step (1) described there, which is moving over all the inline comments.
The old and new tables are simliar. The only real trick here is that `transactionPHID` and `legacyCommentID` mean roughly the same thing (`null` if the inline is a draft, non-null if it has been submitted) but we don't have real `transactionPHID`s yet. We just make some up -- we'll backfill them later.
Two risks here:
- I need to take a second look at the keys on this table. I think we need to tweak them a bit, and it will be less disruptive to do that before this migration than after.
- This will take a while for Facebook, and other large installs with tens of thousands of revisions. I'll communicate this.
I'm otherwise pretty satisfied with this, seems to work well and is pretty low risk / non-disruptive.
Test Plan:
- Before migrating, then after migrating:
- Made a bunch of inlines (drafts, submitted).
- Edited and deleted inlines.
- Verified inlines showed up in preview.
- Verified that inlines aren't indexed when they're drafts (`bin/search index D935`).
- Verified that inlines ARE indexed when they're not drafts.

# Humans can't edit the URL anymore, either.
I think (1) is an actual issue, and this fixes it. I think (2) is pretty fluff, and this doesn't really try to fix it, although it probably improves it.
The fix for (1) is:
- Provide a helper to read a parameter containing either a list of user PHIDs or a list of usernames, so `/?users[]=PHID-USER-xyz` (from a tokenizer) and `/?users=alincoln,htaft` (from an external program) are equivalent inputs.
- Rename all the form parameters to be more digestable (`authorPHIDs` -> `authors`). Almost all of them were in this form already anyway. This just gives us `?users=alincoln` instead of `userPHIDs=alincoln`.
- Inside ApplicationSearch, if a request has no query associated with it but does have query parameters, build a query from the request instead of issuing the user's default query. Basically, this means that `/differential/` runs the default query, while `/differential/?users=x` runs a custom query.

- The list now works on devices, like phones and tablets. This is a requirement to make the rest of Differential work on devices.
- Although ApplicationSearch intentionally presents a simpler interface initially and some options which were one click away before aren't now, it is much more powerful than the search it replaces and allows users to build, save, share, fork, edit, and customize a much wider range of queries. Users who used the old filters frequently can use Advanced Search -> Save Custom Query to create new versions of them, and of any other query. "Edit Queries.." allows users to remove and reorder queries, including builtin queries. Basically, there are like three things which have gone from "1-click" to "a few clicks", and ten trillion things which have gone from "hard/impossible" to "relatively easy".
The local screenshots look a bit iffy, but I think a lot of this is the fakenesss of my test data. If they still feel iffy in production we can tweak them until they feel good, like we did for Maniphest.

The trick here is that some queries are ordered. In these cases, we either need to pass some kind of tuple or do a cursor lookup. For example, if you are viewing revisions ordered by `dateModified`, we can either have the next page be something like:
?afterDateModified=2398329373&afterID=292&order=modified
...or some magical token:
?afterToken=2398329373:292&order=modified
I think we did this in Conpherence, but one factor there was that paging orders update with some frequency. In most cases, I think it's reasonable to pass just the ID and do a lookup to get the actual clause value (e.g., go look up object ID 292 and see what its dateModified is) and I think this is much simpler in general.

Currently, when querying for responsible users (revisions where a given user is either the author or a reviewer), we do this:
- If the query passes a bunch of hard-coded special cases, use a special hard-coded UNION.
- Otherwise, use a very complicated JOIN/WHERE clause.
This is bad for several reasons:
- Tons and tons of hard-coding and special casing.
- The JOIN/WHERE clause performs very poorly for large datasets.
- (As a material consequence, the homepage issues a responsible query which barely misses the hard-coded special cases and goes down the slow path.)
Instead, //always// use the UNION strategy to execute a "responsible" query. Specifically, if we have responsible PHIDs, temporarily add them to the author list and build a normal query, then repeat for reviewers, then UNION any clauses we built.
Fixes T3377. Ref T603. Ref T2625. Depends on D6342.
There's various folklore about UNION ALL / UNION DISTINCT performance. UNION DISTINCT is simpler here and the number of rows is small, although we could use UNION ALL in the form:
SELECT * FROM ((SELECT ...) UNION ALL (SELECT ...) ORDER) GROUP LIMIT
...if we find that there's some performance benefit at some point.

Summary:
Ref T603. This introduces a policy-aware DifferentialDiffQuery and converts most callsites.
I've left unusual callsites (mostly: hard to get the viewer, unusual query, queries related to active diffs) alone for now, so this isn't exhaustive but hits 60-80% of sites.
Test Plan: Created diff; created revision; viewed diffs and revisions; made additional conduit calls.

Differential Revision: https://secure.phabricator.com/D6338
Summary: Ref T603. This is a very old, very bad version of `DifferentialRevisionQuery`. I want to modernize only the latter. Express the remaining callsite of the former in terms of `DifferentialRevisionQuery`.
Test Plan: Executed all four modes of `differential.find`.

Summary: Ref T2222. Currently, we load inline comments by `commentID` here, but we always pass every commentID associated with the revision. Instead, just load non-draft comments by revision ID. This simplifies querying a little bit and is likely faster anyway (draft comments are currently loaded separately).
Test Plan: Looked at some revisions and verified inlines showed up correctly and in the right places.

Summary: Ref T2222. I didn't translate this query properly; reproduce the original.
Test Plan: When viewing a revision with non-draft inline comments by a user other than the viewer, the inline comments now appear on the changesets themselves.

Summary:
Ref T2222. See D6260.
Push all this junk behind a Query so I can move the storage out from underneath it.
Test Plan: Viewed home page, list view, revision. Made draft, looked at preview, submitted draft, viewed inline, replied to inline.

Summary:
Ref T2222.
I'm thinking about how I want to approach the Asana sync, and I want to try to do T2222 first so that we can build it cleanly on top of ApplicationTransactions. I think we can at least walk down this road a little bit and if it turns out to be scary we can take another approach.
I was generally very happy with how the auth migration turned out (seemingly, it was almost completely clean), and want to pursue a similar strategy here. Basically:
- Wrap the new objects in the old objects for reads/writes.
- Migrate all the existing data to the new table.
- Everything hard is done; move things over a piece at a time at a leisurely pace in lots of smallish, relatively-easy-to-understand changes.
This deletes or abstracts all reads of the DifferentialComment table. In particular, these things are **deleted**:
- The script `undo_commits.php`, which I haven't pointed anyone at in a very long time.
- The `differential.getrevisionfeedback` Conduit method, which has been marked deprecated for a year or more.
- The `/stats/` interface in Differential, which should be rebuilt on Fact and has never been exposed in the UI. It does a ton of joins and such which are prohibitively difficult to migrate.
This leaves a small number of reading interfaces, which I replaced with a new `DifferentialCommentQuery`. Some future change will make this actually load transactions and wrap them with DifferentialComment interfaces.
Test Plan: Viewed a revision; made revision comments

Summary:
- Unify all the reference/embed Remarkup rules for Differential, Maniphest, Paste and Ponder.
- Add rules for Pholio.
- Does not yet unify Diffusion or Files (both are a bit more involved).
- Prepare for hovercards.

Summary:
If the revision doesn't have reviewers then it's really not waiting on someone else and the author must take an action.
An improvement would be to check if the reviewers are not disabled but that would require loading their handles.

Summary:
I want to check the work of several people (bootcampers) at once.
This implements the OR filter required for that.
In the next diff, I plan to implement also the AND filter which can be useful too.
Test Plan:
Searched for several people, clicked all filters.
Searched for one person, verified that pretty URL is still created.
