1308a5555f Update client logic for inline comment "Save" and "Cancel" actions
Summary: Ref T13559. Substantially correct the client logic for "Save" and "Cancel" actions to handle unusual cases.

Test Plan:
Quoting behavior:

  - Quoted a comment.
  - Cancelled the quoted comment without modifying anything.
  - Reloaded page.
    - Before changes: quoted comment still exists.
    - After changes: quoted comment is deleted.
  - Looked at comment count in header, saw consistent behavior (before: weird behavior).

Empty suggestion behavior:

  - Created a new comment on a suggestable file.
  - Clicked "Suggest Edit" to enable suggestions.
  - Without making any text or suggestion changes, clicked "Save".
    - Before changes: comment saves, but is empty.
    - After changes: comment deletes itself without undo.

General behavior:

  - Created and saved an empty comment (deletes itself).
  - Created and saved a nonempty comment (saves as draft).
  - Created and saved an empty comment with an edit suggestion (saves).
  - Created and saved an empty comment with a suggestion to entirely delete lines -- that is, no suggestion text (saves).
  - Edited a comment, saved without changes (save).
  - Edited a comment, save deleting all text (saves -- note that this is intentionally without undo, since this is a lot of steps to do by accident).
  - Cancel editing an unchanged comment (cancels without undo).
  - Cancel editing a changed comment (cancels with undo).
    - Undo'd, got text back.
  - Cancel new comment with no text (deletes without undo).
  - Cancel new comment with text (deletes with undo).
    - Undo'd, got text back.
  - Saved a quoted comment with no changes (saves -- note that this is intentionally not a "delete", since just quoting someone seems fine if you click "Save" -- maybe you want to come back to it later).

6fd55d692f Formally track "initial", "committed", and "active" states for inline comments
Summary:
Ref T13559. Various client decisions depend on the "initial" or "committed" states of inline comments. Previously, these were informally constructed from "mostly similar" available values, or glossed over in some cases.

On the server, save the initial state when creating a comment. Save the committed state when applying a "save" operation. Send all three states to the client.

On the client, load and track all three states explicitly.

Test Plan: Created inlines, etc. See followups.

b75517918d When creating an inline comment, populate the content state with the default suggestion text
Summary:
Ref T13559. Currently, the default text for inline comment side-loads in a bizarre way. Instead, when a user creates an inline comment, load the inline context and set it as part of the initial content state.

This allows the side channel (and the code that puts the text in place at the last second on the client) to be removed.

Test Plan: Created inlines, clicked "Suggest Edit". See followup changes.

428fff2e58 Fix an issue when undoing mutiple inline comment deletions
Summary:
Ref T13559. If you create comments A and B, then delete comments A and B, then undo the deletion of A, the UI undoes the deletion of B instead.

This is becasue the undo rows are shipped down with a static scalar metadata reference. When copied multiple times to create multiple undo rows, they reference the same data object.

Preventing this in the general case is a problem with greater scope. For now, just avoid rendering these rows with any metadata so they don't alias a single data object.

Test Plan:
  - Created comments A, B.
  - Deleted comments A, B.
  - Clicked "Undo" on A.
    - Before: Deletion of "B" undone.
    - After: Deletion of "A" undone.

d30c3a961c Make the client authoritative for "Cancel" actions
Summary:
Ref T13559. When the user clicks the "Cancel" button, we sometimes take it to mean "delete" (when the comment is empty).

Both the client and server make a decision about this, and they may not agree, which causes the client to fall out of sync.

201e0d2943 Add support for a "containerPHID" in the worker queue
Summary:
Ref T13591. Worker queue tasks which affect commits currently (mostly) store the commit as an "objectPHID", but do not directly reference the repository the commit belongs to.

This can make certain operations (like "change the priority of all tasks affecting repository Y") more difficult than it needs to be.

Support a "containerPHID", similar to the field of the same name on builds, that can store a parent object like a repository and better support operations against subsets of tasks.

See also D11044 for the genesis of "objectPHID".

This depends on the introduction of storage patch phases (in D21529) so that earlier migrations which queue worker tasks don't try to insert this column before it actually exists.

Test Plan:
  - Ran `bin/storage upgrade`.
  - No callers yet, see further changes for usage.

32942f6232 Introduce storage patch "phases" to allow index-rebuilding patches to execute after worker queue schema changes
Summary:
Ref T13591. Some storage patches queue worker tasks, currently always to rebuild search indexes.

These patches can not execute in creation order if a later patch modifies the worker task table, since they'll try to perform a modern INSERT against an out-of-date table schema. Such a modification is desirable in the context of T13591, but making it causes these patches to fail.

Patches have an existing "after" mechanism which allows them to have explicit dependencies. This mechanism could be used to resolve this issue, but all patches with a dependency like this would need to be updated every time the queue table changes.

Instead, introduce "phases" to provide broader ordering rules. There are now two phases: "default" and "worker". Patches in the "worker" phase execute after patches in the "default" phase.

Phases may eventually be further separated, but

Test Plan:
  - Ran `bin/storage status`, saw patches annotated with phases.
  - Will apply `containerPHID` changes on top of this.

671986592b Add a missing "GROUP BY" to MailQuery when querying for multiple recipients
Summary:
See <https://discourse.phabricator-community.org/t/mail-details-view-broken/4315>. The change in D21400 detects a missing "GROUP BY" in some variations of this query.

Specifically, we may join multiple recipient rows (since mail may have multiple recipients) and then fail to group the results.

Fix this by adding the "GROUP BY". Additionally, remove the special-cased behavior when no authors or recipients are specified -- it's complicated and not entirely correct (e.g., may produce a "no object" instead of a policy error when querying by ID), and likely predates overheating.

Test Plan:
  - Disabled `metamta.one-mail-per-recipient` in Config.
  - Generated a message to 2+ recipients.
  - Viewed the message detail; queried for the message by specifying 2+ recipients.
  - Viewed the unfiltered list of messages, saw the query overheat.

bc4f86d279 When a new, deleted, draft inline is revived with "Undo", undelete it
Summary:
See PHI1876. Normally, deleted inlines are undeleted with an "undelete" operation, which clears the "isDeleted" flag.

However, when an inline is deleted implicitly by using "Cancel" without first saving it, the flag currently isn't cleared properly. This can lead to cases where inlines seem to vanish (they are shown to the user in the UI, but treated as deleted on submission).

Test Plan:
There are two affected sequences here:

  - Create a new inline, type text, cancel, undo.
  - Create a new inline, type text, cancel, undo, save.

The former sequence triggers an "edit" operation. The subsequent "Save" in the second sequence triggers a "save" operation.

It's normally impossible in the UI to execute a "save" without executing an "edit" first, but "save" clearly should undelete the comment if you get there somehow, so this change clears the deleted flag in both cases for completeness.

  - Executed both sequences, saw comment persist in preview, on reload, and after submission.

72f149bf39 Require rows passed to "loadAllFromArray()" have unique keys
Summary:
See PHI1809, which identified a bug in Project search where queries with a large number of slugs could paginate improperly.

This change detects problems in this category: cases where multiple rows with the same ID are passed to "loadAllFromArray()". It's likely that all cases it detects are cases where a GROUP BY is missing.

Since this might have some false positives or detect some things which aren't fundamentally problematic, I'm planning to hold it until the next release.

78d1b62bb8 Streamline handling of Futures and PIDs in daemons
Summary:
Ref T13555. Currently, the daemon future may resolve into a failure state immediately inside "start()", and not have a valid PID when we read it.

Instead, read PIDs from the current active future in all cases, using "hasPID()" to test for the presence of a valid PID.

Since we don't query the PID immediately, we no longer need to explicitly start the future.

Also fix an issue where the same future could be added to the overseer pool more than once if it threw on "resolve()". In general:

  - Before we "resolve()" a future, detach it from the DaemonHandle: we're always done with it.
  - Catch exceptions on resolution and treat them the same way as subprocess resolution errors. These aren't common, but are possible in the general case.
  - Have DaemonHandle add futures to the future pool directly when they're created.

Test Plan:
  - Ran daemons with intentional subprocess creation failures, saw clean recovery.
  - Ran daemons with intentional resolution exceptions, saw clean recovery.

fcb75d0503 Fix an issue where prose diffing may fail after hitting the PCRE backtracking limit
Summary:
Fixes T13554. For certain prose diff inputs and PCRE backtracking limits, this regular expression may back track too often and fail.

A characteristic input is "x x x x ...", i.e. many sequences where `(.*?)\s*\z` looks like it may be able to match but actually can not.

I think writing an expression which has all the behavior we'd like without this backtracking issue isn't trivial (at least, I don't think I know how to do it offhand); just use a strategy based on "trim()" insetad, which avoids any PCRE complexities here.

Test Plan: Locally, this passes the "x x x ..." test which the previous code failed. I'm not including that test because it won't reproduce across values of "pcre.backtrac_limit", PCRE versions, etc.

22de618d3b When acquiring a GlobalLock, put good connections that just got unlucky back in the pool
Summary:
See PHI1794, which describes a connection exhaustion issue with a large number of webhook tasks in queue.

The "GlobalLock" mechanism manages a separate connection pool from the main pool, and webhook workers immediately try to grab a webhook lock with a 0-second wait when they start. So far, this is fine.

Prior to this change, good connections which fail to acqiure a lock are discarded. This can lead to connection exhaustion as the worker rapidly cycles through lock attempts: the connections will remain open for at least 60 seconds (since D16389) in an effort to avoid outbound port exhaustion, but they're effectively orphaned because they aren't part of the main pool and aren't part of the lock pool. We're basically leaking a connection every time we fail to lock.

Failing to lock doesn't mean we need to discard the connection: it's a completely suitable connection for reuse. Instead of dropping it on the floor, put it into the lock pool.

Test Plan:
  - Used "bin/webhook call ... --count 10000 --background" to queue a large number of webhook calls against a slow ("sleep(15);") webhook.
  - Used "bin/phd launch 32 taskmaster" to start taskmasters.
  - Observed MySQL connection behavior:
    - Before change: 2048 configured connections immediately exhausted.
    - After change: connections stable at ~160ish.
  - Ran queue for a while, saw expected single-threaded calls to webhook.

36075f6ce5 Correct a prose diff behavior when prose pieces include newlines
Summary:
See <https://discourse.phabricator-community.org/t/bad-regex-in-prose-diff-logic/3969>.

The prose splitting rules normally guarantee that newlines appear only at the beginning or end of blocks. However, if a prose sentence ends with text like "...x\n.", we can end up with a newline inside a "sentence".

If we do, the regular expression that breaks it into pieces will fail.

Arguably, this is an error in how sentences are split apart (we might prefer to split this into two sentences, "x\n" and ".", rather than a single "x\n." sentence) but in the general case it's not unreasonable for blocks to contain newlines, so a simple fix is to make the pattern more robust.

Test Plan: Added a failing test which includes this behavior, made it pass.

a590db28b2 Fix an issue where non-ID changeset state keys were used as changeset IDs
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".

b48a22bf50 Make "editing" state persistent for inline comments
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.

186a12ef7f Replace nonexistent "withPHIDs()" in ChangesetQuery with "withIDs()"
Summary:

Changesets do not have PHIDs, and the Query has no "withPHIDs()" method. The keys in the viewstate storage are (usually) IDs.

    - Viewed Diff 1.
    - Hid file A.
    - Viewed Diff 2.
  - Before patch: exception about call to "withPHIDs()", which does not exist for ChangesetQuery.

f21f1d8ab9 Update the diff table of contents to use hierarchical views and edit distance renames
Summary:
Ref T13520. Generally, make the table of contents look and more like the paths panel:

  - Show a hierarchy, with compression for single-sibling children.
  - Use the same icons, instead of "M D" and "(img)" stuff.
  - Use EditDistanceMatrix to do a piece-by-piece diff of paths changes.
  - Show path changes within the path list.

I'm not entirely sold on this, but it was complicated to write and I've never heard the term "sunk cost fallacy". I think this is mostly a net improvement, but may need some adjustments and followup.

3984c14260 Tokenize external editor links so they can be safely materialized on the client
Summary:
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.)

Test Plan:
  - Added a bunch of tests for the actual parser.
  - Used "Open in Editor" in Differential.

c3c55d82ae Make "renderer", "engine", and "encoding" sticky across reloads in Differential and Diffusion
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.
  - Started typing a comment, cancelled it, hit the undo UI.

Summary:
Ref T13455. Add container-level storage for persistent view state, and persist "Highlight As..." inside it.

The storage generates a "PhabricatorChangesetViewState" configuration object as an output.

When preferences are expressed on a diff and that diff is later attached to a revision, we attempt to copy the preferences.

The internal storage tracks per-changeset settings, but currently always uses "last update wins" to apply the settings in the UI.

Test Plan:
  - Viewed revisions, changed highlighting, reloaded. Saw highlighting stick in revision view and standalone view.
  - Viewed commits, changed highlighting, reloaded. Saw highlighting stick.
  - Created a diff, changed highlighting, turned it into a revision, saw highlighting persist.

fb3f423279 Remove broken and unfixable "prefix" ngram behavior
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.

Test Plan: Searched for "om", hit "random.txt".

Summary:
Ref T13509. Now that the compiler can parse these queries, actually implement them.

These are fairly easy to implement:

  - For present, just "JOIN". If it works, the field is present.
  - For absent, we "LEFT JOIN" and then "WHERE any_column IS NULL".

Test Plan: Searched for various documents with and without fields present, got sensible results in Maniphest. For example, "body:-" finds tasks with no body, "body:- duck" finds tasks with no body and "duck" elsewhere in the content, and so on.

Summary:
Ref T13509. Currently, functions are "sticky", but this stickness is in the query execution layer.

Instead:

  - move stickiness to the query compiler; and
  - make it so that functions are not sticky if their arguments are quoted.

For example:

  - `title:x y` previously meant `title:x title:y` (and still does). The "title:" is sticky.
  - `title:"x" y` previously meant `title:x title:y`. It now means `title:x all:y`. The "title:" is not sticky because the argument is quoted.

54bcbdaba9 Fix an XSS issue with certain high-priority remarkup rules embedded inside lower-priority link rules
Summary:
See <https://hackerone.com/reports/758002>. The link rules don't test that their parameters are flat text before using them in unsafe contexts.

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.

Tested examples in HackerOne report. A simple example of broken (but not unsafe) behavior is:

```
[[ `x` | `y` ]]
