Currently, the Viewer when performing revision updates in response to commits may be an arbitrary low-privilege user (an Application, a disabled User, a bot, a mailing list, etc).
Today, this leads to an exception when trying to make API calls.
Ideally, we probably would not perform the update in these cases. However, performing the update isn't a policy violation and is generally less surprising than not performing it, so continue performing it for now: just use the omnipotent user to interact with the API.
Test Plan:
- Authored a commit as a bot user without permission to view the repository or revision.

Ref T13623. When paginating notifications, we may currently construct a query which:
- loads from non-unique rows; and
- returns multiple results.
In particular, `chronologicalKey` isn't unique across the whole table (only for a given viewer). We can get away with this because no user-facing view of notifications is truly "every notification for every viewer" today.
One fix would be to implicitly force the paging query to include `withUserPHIDs(viewerPHID)`, but puruse a slightly more general fix:
- Load only unique stories.
- Explictly limit the pagination subquery to one result.
Test Plan:
- Set page size to 1, inserted duplicate notifications of all stories for another user, clicked "Next", got the GROUP BY error.
- Applied the "only load unique stories" part of the change, got a "expected one row" error instead.

Ref T13587. Currently, when a document is reindexed by Ferret, the old document is completely discarded and a new version is inserted to replace it.
This approach is simple to implement, but can lead to exhaustion of the ngram AUTO_INCREMENT id column in reasonable circumstances.
Conceptually, this approach "should" be fine and this exhaustion is an awkard implementation detail. However, since it's easy to be less wasteful when performing document updates and all the other approaches are awkward or leaky in other ways that are probably worse, use a more complex implementation to avoid executing unnecessary INSERT statements.

Ref T13600. When migrating observed repositories between cluster services, impact can be better controlled by fetching a copy of the repository on the target host before clusterizing it.
In particular, in the Phacility cluster, migrations are generally from one shared shard to one dedicated shard. It's helpful to perform these migrations synchronously without waiting for the cluster to sync in the background (helpful in the sense that there are fewer steps and fewer commands to run).
This supports an "--observe" mode to the internal "bin/services load-repository" workflow, which transfers repository data by refetching it from the remote rather than by getting it from the older host. This fetch occurs before cluster configuration is adjusted.

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.

- No callers yet, see further changes for usage.

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

- Ran `bin/storage status`, saw patches annotated with phases.

Summary:
Ref T13591. There are currently two pathways to queue an import task for a commit: via repository discovery, or via a ref becoming permanent.
These pathways duplicate some logic and have behavioral differences: one does not set `objectPHID` properly, one does not set the priority correctly.
Unify these pathways, make them both set `objectPHID`, and make them both use the same priority logic.
Test Plan:
- Discovered refs.
- See later changes in this series for more complete test cases.

Summary:
Ref T13591. Currently, the "IMPORTED_PERMANENT" flag (previously "IMPORTED_CLOSEABLE", until D21514) flag is set by using the result of "shouldPublishRef()".
This method returns the wrong value for the flag when there is a repository-level reason not to publish the ref (most commonly, because the repository is currently importing).
Although it's correct that commits should not be published in an importing repository, that's already handled in the "PublishWorker" by testing "shouldPublishCommit()". The "IMPORTED_PERMANENT" flag should only reflect whether a commit is reachable from a permanent ref or not.
- Move the relevant logic to a new method in Publisher.
- Fill "IMPORTED_PERMANENT" narrowly from "isPermanentRef()", rather than broadly from "shouldPublishRef()".
- Deduplicate some logic in "PhabricatorRepositoryRefEngine" which has the same intent as the logic in the Publisher.
Test Plan:
- Ran discovery on a new repository, saw permanent commits marked as permanent from the beginning.
- See later changes in this patch series for additional testing.

Summary:
Ref T13591. This is an old flag with an old name, and there's an import bug because the outdated concept of "closable" is confusing two different behaviors.
This flag should mean only "is this commit reachable from a permanent ref?". Rename it to "IMPORTED_PERMANENT" to make that more clear.
Rename the "Unpublished" query to "Permanent" to make that more clear, as well.

Summary:
Ref T13575. Since PHP builtin webserver support was added, the pathway for parsing request parameters became more complex. We now rebuild "$_REQUEST" later, and this rebuild will destroy any mutations made to it here, so the assignment to "__path__" is lost.
Instead of "validating" the request path, make this method "read" the request path and store it explicitly, so it will survive any later request mutations.

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.

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.

In particular, commits have multiple dates (authored, committed, pushed) but this header shows only one. It currently shows the author identity and the commit date, which isn't entirely correct.

- Left inlines on lines 14, 17-19, and 16-26 (end of the file) on Diff 1.
- Before: saw inlines incorrectly adjusted to lines 15, 18, and 17 on Diff 2. Before D21435, the last inline was culled by the rendering engine.

Summary:
See PHI1834. Currently, the inline adjustment engine can sometime "adjust" an inline off the end of a diff. If it does, we lay it out on an invalid display line here and never render it.
Instead, make sure that layout never puts a comment on an invalid line, so the UI is robust against questionable decisions by the adjustment engine: no adjustment should be able to accidentally discard an inline.
Test Plan:
- Created a two diff revision, where Diffs 1 and 2 have "alphabet.txt" with A-Z on one line each. The file is unchanged across diffs; some other file is changed.
- Added a comment to lines P-Z of Diff 1.
- Before: comment is adjusted out of range on Diff 2 and not shown in the UI.

Just kick it out of prototype.

However, this has a side effect: the sequence is now selected with a single click. I didn't read the docuementation on the CSS property thoroughly and missed this in testing, since I was focused on drag-selection behavior.

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.

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.

Summary:
Ref T2495. See PHI1814. Currently, Phabricator replaces tabs with spaces when rendering diffs.
This may or may not be the best behavior in the long term, but it gives us more control over expansion of tabs than using tab literals.
However, one downside is that you can use your mouse cursor to select "half a tab", and can't use your mouse cursor to distinguish between tabs and spaces. Although you probably shouldn't be doing this, this behavior is less accurate/correct than selecting the entire block as a single unit.
A specific correctness issue with this behavior is that the entire block is copied to the clipboard as a tab literal if you select any of it, so two different visual selection ranges can produce the same clipboard content.
This particular behavior can be improved with "user-select: all", to instruct browsers to select the entire element as a single logical element. Now, selecting part of the tab selects the whole thing, as though it were really a tab literal.
(Some future change might abandon this approach and opt to use real tab literals with "tab-size" CSS, but we lose some ability to control alignment behavior if we do that and it doesn't have any obvious advantages over this approach other than cursor selection behavior.)
Test Plan:
- In Safari and Firefox, dragged text to select a whitespace-expanded tab literal. Saw browsers select the whole sequence as though it were a single tab.
- In Chorme, this also mostly works, but there's some glitchiness and flickering. I think this is still a net improvement, it's just not as smooth as Safari and Firefox.

- The author pings reviewers to ask them to look at it.
...the reviewers may not be able to move the review forward if the review is currently a "Draft". They can only "Commandeer" or ask the author to "Request Review" as ways forward.
Although I'm hesitant to support review actions (particularly, "Accept") on draft revisions, I think there's no harm in allowing reviewers to skip tests and promote the revision out of draft as an explicit action.
Additionally, lightly specialize some of the transaction strings to distinguish between "request review from draft" and other state transitions.
Test Plan:

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.

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.

Currently, Phortune attempts to prevent users from removing themselves as account managers. It does this by checking that the new list includes them.
Usually this is sufficient, because you can't normally edit an account unless you're already a manager. However, we get the wrong result (incorrect rejection of the edit) if the actor is omnipotent and the acting user was not already a member.
It's okay to edit an account into a state which doesn't include you if you have permission to edit the account and aren't already a manager.
Specifically, this supports more formal tooling around staff modifications to billing accounts, where the actor has staff-omnipotence and the acting user is a staff member and only used for purposes of leaving a useful audit trail.

Summary:
Ref T13529. Now that instances can be renamed, an instance may have multiple valid SSH usernames and the preferred SSH username may not be the intenal instance name.
`PhacilitySiteSource` should already always set `diffusion.ssh-username` correctly, to the current preferred SSH username (which may be "new-name" after a rename from "old-name"), so we should never be able to reach this code without an accurate `diffusion.ssh-username` value available.
The code to resolve names into instances also already works for both "ssh old-name@..." and "ssh new-name@...".
So I believe this code has no beneficial effects and only causes harm: it may force us to return "old-name" when falling through would correctly return "new-name".
Test Plan:
- Previously: renamed an instance, then SSH'd to it using both the old and new names. Both work.
- Previously: verified that `diffusion.ssh-username` is set correctly after a rename.
- Verified that Diffusion "Clone" UI now shows "new-name" after an instance rename.
- The real question here is: does this break something I'm not thinking of? And the change probably has to go to production to answer that.

However, we can just ignore the range behavior for complex content and treat the entire block as selected. This isn't quite as fancy as the source behavior, but pretty good.
Also, adjust unified diff behavior to work correctly with highlighting and range selection.

Ref T13454. See <https://discourse.phabricator-community.org/t/newly-created-ssh-private-keys-with-passphrase-not-working-anymore/3883>.
After changes to distinguish between invalid and passphrase-protected keys, SSH private key management code incorrectly uses "-y ..." ("print public key") when it means "-p ..." ("modify input file, removing passphrase"). This results in the command having no effect, and Passphrase stores the raw input credential, not the stripped version.
We can't recover the keys because we don't store the passphrase, so no migration here is really possible. (We could add more code to detect this case, but it's presumably rare.)
Also, correct the behavior of the "Show Public Key" action: this is available for users who can see the credential and does not require edit permission.

- 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".

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.

Summary:
See PHI1719. User agents making hard-coded requests to "/favicon.ico" currently 404. This is a mild source of log noise, and we can reasonably route this request.
Limitations:
- This only routes the "PlatformSite". Other sites (custom Phame blogs, third-party sites, Phurl redirectors) won't route here for now.
- This returns a "Location:" redirect to the correct resource rather than icon data directly. This produces the right icon with the right caching behavior, and returning icon data directly is difficult in the general case. However, it won't perform/cache as well as a direct response would.
Test Plan:
- Visted `/favicon.ico`.
- Before: 404.
- After: redirect to favicon.

Summary:
Ref T13526. Currently, if a build plan is restricted, viewers may fatal when trying to view related builds.
The old behavior allowed them to see the build even if they can not see the build plan. This is sort of incoherent, but try to stabilize things before fixing this.
Test Plan:
This is a muddy change.
- Created a build with a build plan that Alice can't see.
- As Alice, viewed the build page (restricted before, restricted after); the buildable page (fatal before, works after).
- Also viewed a revision page (works before and after, but user-reported fatal).

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.
Test Plan: Viewed various changes in Differential and Diffusion, saw a more usable table of contents.

Summary:
Ref T13523. Currently, when building a "comparison" changeset, metadata is taken from the left changeset. This is somewhat arbitrary.
This means that intradiffs of images don't work properly because the rendered changeset has only the left (usually "old") information.
Later, some of the code attempts to ignore the file data stored on the changeset and reconstruct the correct file data, which is how the result ends up not-completely-wrong.
Be more careful about building sensible-ish metadata, and then just use it directly later on. This fixes the "spooky" code referencing D955 + D6851.
There are some related issues, where "change type" and "file type" are selected arbitrarily and then used to determine whether the change has an "old/new" state or not (i.e., is the left side of the diff empty, since the change creates the file)?
In many cases, neither of the original changesets have a "change type" which will answer this question correctly. Separate this concept from "has state" from "change type", and make more of the code ask narrower questions about the specific conditions or states it cares about, rather than "change type".
Test Plan:
- Created a revision with Diff 1, Diff 2, and Diff 3. Diff 1 takes an image from "null -> A". Diff 2 takes the same image from "null -> B". Diff 3 takes the same image from "A -> B'.
- Intradiffed 1v2 and 1v3.
- Before patch:
- Left side usually missing, which is incorrect (should always be "A").
- Change properties are a mess ("null -> image/png" for MIME type, e.g.)
- Uninteresting/incorrect "unix:filemode" stuff.
- After patch;
- Left side shows state "A".
- Change properties only show size changes (which is correct).

We currently do not accept this as a "truthy" value, but it's reasonable and unambiguous. Accept "True", "TRUE", "tRuE", etc.

Summary: See PHI1710. Until D21044, some transactions could omit "value" and apply correctly. This now throws an exception when accessing `$xaction['value']`. All transactions are expected to have a "value" key, so require it explicitly rather than implicitly.

- Created a revision affecting `cat.png` and `quack.txt` (currently, there must be 2+ changesets to trigger the hide logic).
- Updated it with the exact same changes.
- Viewed revision:
- Saw the image renderered in the interdiff.
- Applied patch.
- Ran `bin/differential rebuild-changesets ...`.

Summary:
Ref T4369. During T13507, I set my "max_post_size" to a very small value, like 7 (i.e., 7 bytes). This essentially disables "enable_post_data_reading" even if the setting is technically on.
This breaks forms which use "multipart/form-data", which are rare but not nonexistent. Notably, forms in Config use this setting (because of `ui.header` stuff?) although perhaps they should not or no longer need to.
This can be fixed by parsing the raw input.
Since the only reason we don't parse the raw input is concern that we may not be able to read it (per documentation, but never actually observed), and we do a `strlen()` test anyway, just read it unconditionally.
This should fix cases where POST data wasn't read because of "max_post_size" without impacting anything else.
Test Plan: With very small "max_post_size", updated "ui.footer-items" in Config. Before: form acted as a no-op. After: form submitted.

Add a GC with a long default collection policy (180 days) so installs can manage the size of this table if it becomes necessary.

Summary:
Ref T13516. Currently, the "File Tree" element is a semi-dynamic side panel that's implemented as a special mode of a side nav panel.
This implementation is fairly clunky, and arose from organic growth out of the side nav. As such, it has some weird behaviors, doesn't have builtin support for show/hide, and can't generalize easily.
Introduce a "FormationView" which supports loading a page up with piles of side panels in various modes.
