Summary:
Depends on D20321. Fixes T12175. Ref T13074. Now that before/after PHIDs are suggestions, we can give the server a more complete view of what the client is trying to do so we're more likely to get a good outcome if the client view is out of date.
Instead of passing only the one directly adjacent card PHID, pass all the card PHIDs that the client thinks are in the same group.
(For gigantic columns with tens of thousands of tasks this might need some tweaking -- like, slice both lists down to 10 items -- but we can cross that bridge when we come to it.)
Test Plan:
- Dragged some cards around to top/bottom/middle positions, saw good positioning in all cases.
- In two windows, dragged stuff around on the same board. At least at first glance, conflicting simultaneous edits seemed to do reasonable things.

Summary:
Depends on D20320. Ref T12175. Ref T13074. Currently, when you move a card between columns, the internal transaction takes exactly one `afterPHID` or `beforePHID` and moves the card before or after the specified card.
This is a fairly strict interpretation and causes a number of practical issues, mostly because the user/client view of the board may be out of date and the card they're dragging before or after may no longer exist: another user might have moved or hidden it between the last client update and the current time.
In T13074, we also run into a more subtle issue where a card that incorrectly appears in multiple columns fatals when dropped before or after itself.
In all cases, a better behavior is just to complete the move and accept that the position may not end up exactly like the user specified. We could prompt the user instead:
> You tried to drop this card after card X, but that card has moved since you last loaded the board. Reload the board and try again.
...but this is pretty hostile and probably rarely/never what the user wants.
Instead, accept a list of before/after PHIDs and just try them until we find one that works, or accept a default position if none work. In essentially all cases, this means that the move "just works" like users expect it to instead of fataling in a confusing/disruptive/undesirable (but "technically correct") way.
(A followup will make the client JS send more beforePHIDs/afterPHIDs so this works more often.)
We could eventually add a "strict" mode in the API or something if there's some bot/API use case for precise behavior here, but I suspect none exist today or are (ever?) likely to exist in the future.
Test Plan:
- (T13074) Inserted two conflicting rows to put a card on two columns on the same board. Dropped one version of it underneath the other version. Before: confusing fatal. After: cards merge sensibly into one consistent card.
- (T12175) Opened two views of a board. Moved card A to a different column on the first view. On the second view, dropped card B under card A (still showing in the old column). Before: confusing fatal. After: card ended up in the right column in approximately the right place, very reasonably.

Instead, do this in Javascript. This is a little more complicated but: it works; and we can do the fade when you get //near// the element instead of actually over it, which feels a little better.

Ref T5474. In 99% of cases, a separate "archived/active" status for triggers probably doesn't make much sense: there's not much reason to ever disable/archive a trigger explcitly, and the archival rule is really just "is this trigger used by anything?".
(The one reason I can think of to disable a trigger manually is because you want to put something in a column and skip trigger rules, but you can already do this from the task detail page anyway, and disabling the trigger globally is a bad way to accomplish this if it's in use by other columns.)
Instead of adding a separate "status", just track how many columns a trigger is used by and consider it "inactive" if it is not used by any active columns.
Test Plan: This is slightly hard to test exhaustively since you can't share a trigger across multiple columns right now, but: rebuild indexes, poked around the trigger list and trigger details, added/removed triggers.

The "Edit" controller is custom instead of being driven by "EditEngine" because I expect it to be a Herald-style "add new rules" UI, and EditEngine isn't a clean match for those today (although maybe I'll try to move it over).
The general idea here is:
- Triggers are "real" objects with a real PHID.
- Each trigger has a name and a collection of rules, like "Change status to: X" or "Play sound: Y".
- Each column may be bound to a trigger.
- Multiple columns may share the same trigger.
- Later UI refinements will make the cases around "copy trigger" vs "reference the same trigger" vs "create a new ad-hoc trigger" more clear.
- Triggers have their own edit policy.
- Triggers are always world-visible, like Herald rules.

After the cursor changes, we may fatal on pages with a large number of children

```
((SELECT revision.* FROM ... ORDER BY rank) UNION ALL (SELECT revision.* FROM ... ORDER BY rank)) ORDER BY rank

The internal "ORDER BY rank" is technically redundant (probably?), but doesn't hurt anything, and makes construction easier.
The problem is that the outer "ORDER BY rank" at the end, which attempts to order the results of the two parts of the UNION, can't actually order them, since `rank` wasn't selected.
(The column isn't actually "rank", which //is// selected -- it's the document modified/created subcolumns, which are not.)
To fix this, actually select the fulltext columns into the result set.

Summary:
Ref T13259. Currently, queries set a flag and return a partial result set when they overheat. This is mostly okay:
- It's very unusual for queries to overheat if they don't have a real viewer.
- Overheating is rare in general.
- In most cases where queries can overheat, the context is a SearchEngine UI, which handles this properly.
In T13259, we hit a case where a query with an omnipotent viewer can overheat: if you have more than 1,000 consecutive commits in the database with invalid `repositoryID` values, we'll overheat and bail out. This is pretty bad, since we don't process everything.
Change this beahvior:
- Throw by default, so this stuff doesn't slip through the cracks.
- Handle the SearchEngine case explicitly ("it's okay to overheat, we'll handle it").
- Make `QueryIterator` disable overheating behavior: if we're iterating over all objects, we want to hit the whole table even if most of it is garbage.
There are some cases where this might cause new exception behavior that we don't necessarily want. For example, in Owners, each package shows "recent commits in this package". If you can't see the first 1,000 recent commits, you'd previously get a slow page with no results. Now you'll probably get an exception.
If these crop up, I think the best approach for now is to deal with them on a case-by-case basis and see how far we get. In the "Owners" case, it might be good to query by repositories you can see first, then query by commits in the package in those repositories. That should give us a better outcome than any generic behavior we could implement.
Test Plan:
- Added 100000 to all repositoryID values for commits on my local install.
- Before making changes, ran `bin/repository rebuild-identities --all --trace`. Saw the script process 1,000 rows and exit silently.

Summary:
Ref T13259.
(NOTE) This is "infrastructure/guts" only and breaks some stuff in Query subclasses. I'll fix that stuff in a followup, it's just going to be a larger diff that's mostly mechanical.
When a user clicks "Next Page" on a tasks view and gets `?after=100`, we want to show them the next 100 //visible// tasks. It's possible that tasks 1-100 are visible, but tasks 101-788 are not, and the next visible task is 789.
We load task ID `100` first, to make sure they can actually see it: you aren't allowed to page based on objects you can't see. If we let you, you could use "order=title&after=100", plus creative retitling of tasks, to discover the title of task 100: create tasks named "A", "B", etc., and see which one is returned first "after" task 100. If it's "D", you know task 100 must start with "C".
Assume the user can see task 100. We run a query like `id > 100` to get the next 100 tasks.
However, it's possible that few (or none) of these tasks can be seen. If the next visible task is 789, none of the tasks in the next page of results will survive policy filtering.
So, for queries after the initial query, we need to be able to page based on tasks that the user can not see: we want to be able to issue `id > 100`, then `id > 200`, and so on, until we overheat or find a page of results (if 789-889 are visible, we'll make it there before overheating).
Currently, we do this in a not-so-great way:
- We pass the external cursor (`100`) directly to the subquery.
- We query for that object using `getPagingViewer()`, which is a piece of magic that returns the real viewer on the first page and the omnipotent viewer on the 2nd..nth page. This is very sketchy.
- The subquery builds paging values based on that object (`array('id' => 100)`).
- We turn the last result from the subquery back into an external cursor (`200`) and save it for the next time.
Note that the last step happens BEFORE policy (and other) filtering.
The problems with this are:
- The phantom-schrodinger's-omnipotent-viewer thing isn't explicity bad, but it's sketchy and generally not good. It feels like it could easily lead to a mistake or bug eventually.
- We issue an extra query each time we page results, to convert the external cursor back into a map (`100`, `200`, `300`, etc).
- In T13259, there's a new problem: this only works if the object is filtered out for policy reasons and the omnipotent viewer can still see it. It doesn't work if the object is filtered for some other reason.
To expand on the third point: in T13259, we hit a case where 100+ consecutive objects are broken (they point to a nonexistent `repositoryID`). These objects get filtered unconditionally. It doesn't matter if the viewer is omnipotent or not.
In that case: we set the next external cursor from the raw results (e.g., `200`). Then we try to load it (using the omnipotent viewer) to turn it into a map of values for paging. This fails because the object isn't loadable, even as the omnipotent viewer.
---
To fix this stuff, the new approach steps back a little bit. Primarily, I'm separating "external cursors" from "internal cursors".
An "External Cursor" is a string that we can pass in `?after=X` URIs. It generally identifies an object which the user can see.
An "Internal Cursor" is a raw result from `loadPage()`, i.e. before policy filtering. Usually, (but not always) this is a `LiskDAO` object that doesn't have anything attached yet and hasn't been policy filtered.
We now do this, broadly:
- Convert the external cursor to an internal cursor.
- Execute the query using internal cursors.
- If necessary, convert the last visible result back into an external cursor at the very end.
This fixes all the problems:
- Sketchy Omnipotent Viewer: We no longer ever use an omnipotent viewer. (We pick cursors out of the result set earlier, instead.)
- Too Many Queries: We only issue one query at the beginning, when going from "external" to "internal". This query is generally unavoidable since we need to make sure the viewer can see the object and that it's a real / legitimate object. We no longer have to query an extra time for each page.
- Total Failure on Invalid Objects: we now page directly with objects out of `loadPage()`, before any filtering, so we can page over invisible or invalid objects without issues.
This change switches us over to internal/external cursors, and makes simple cases (ID-based ordering) work correctly. It doesn't work for complex cases yet since subclasses don't know how to get paging values out of an internal cursor yet. I'll update those in a followup.
Test Plan: For now, poked around a bit. Some stuff is broken, but normal ID-based lists load correctly and page properly. See next diff for a more detailed test plan.

Summary:
See PHI1134. Previously, see T13082 and D19969 for some sort-of-related stuff.
Currently, edits work roughly like this:
- Suppose we're editing object X, and we're also going to edit some other object, Y, because X mentioned Y or the edit is making X a child or parent of Y, or unblocking Y.
- Do the actual edit to X, including inverse edits ("alice mentioned Y on X.", "alice added a child revision: X", etc) which apply to Y.
- Run Herald rules on X.
- Publish the edit to X.
The "inverse edits" currently do this whole process inline, in a sub-editor. So the flow expands like this:
- Begin editing X.
- Update properties on X.
- Begin inverse-edge editing Y.
- Update properties on Y.
- Run (actually, skip) Herald rules on Y.
- Publish edits to Y.
- Run Herald rules on X.
- Publish edits to X.
Notably, the "Y" stuff publishes before the "X" Herald rules run. This creates potential problems:
- Herald rules may change the name or visibility policy of "X", but we'll publish mail about it via the edits to Y before those edits apply. This is a problem only in theory, we don't ship any upstream rules like this today.
- Herald rules may "Require Secure Mail", but we won't know that at the time we're building mail about the indirect change to "Y". This is a problem in practice.
Instead, switch to this new flow, where we stop the sub-editors before they publish, then publish everything at the very end once all the edits are complete:
- Begin editing X.
- Update properties on X.
- Begin inverse-edge editing Y.
- Update properties on Y.
- Skip Herald on Y.
- Run Herald rules on X.
- Publish X.
- Publish all child-editors of X.
- Publish Y.
Test Plan:
- Created "Must Encrypt" Herald rules for Tasks and Revisions.
- Edited object "A", an object which the rules applied to directly, and set object "B" (a different object which the rules did not hit) as its parent/child and/or unblocked it.
- In `bin/mail list-outbound`, saw:
- Mail about object "A" all flagged as "Must Encrypt".
- Normal mail from object B not flagged "Must Encrypt".
- Mail from object B about changing relationships to object A flagged as "Must Encrypt".

Summary:
Fixes T13265. See that task for discussion. Briefly:
- For mailers that use other mailers (SMTP, Sendmail), optionally let administrators set `"message-id": false` to improve threading behavior if their local Postfix is ultimately sending through SES or some other mailer which will replace the "Message-ID" header.
Also:
- Postmark is currently marked as supporting "Message-ID", but it does not actually support "Message-ID" on `secure.phabricator.com` (mail arrives with a non-Phabricator message ID). I suspect this was just an oversight in building or refactoring the adapter; correct it.
- Remove the "encoding" parameter from "sendmail". It think this was just missed in the cleanup a couple months ago; it is no longer used or documented.
Test Plan: Added and ran unit tests. (These feel like overkill, but this is super hard to test on real code.) See T13265 for evidence that this overall approach improves behavior.

Summary:
Ref T13074. Currently, if you "Move Tasks to Column..." on a board and some of the tasks require MFA to edit, the workflow fatals out.
After this change, it works properly. You still have to answer a separate MFA prompt for //each// task, which is a little ridiculous, but at least doable. A reasonable future refinement would be to batch these MFA prompts, but this is currently the only use case for that.
Test Plan: Set a task to a "Require MFA" status, bulk-moved it with other tasks on a workboard. Was prompted, answered MFA prompt, got a move.

Summary:
See PHI1098. When users comment on objects, they are automatically subscribed. And when `@alice` mentions `@bailey` on a task, that usually subscribes `@bailey`.
These rules make less sense if the user is a bot. There's generally no reason for a bot to automatically subscribe to objects it acts on (it's not going to read email and follow up later), and it can always subscribe itself pretty easily if it wants (since everything is `*.edit` now and supports subscribe transactions).
Also, don't subscribe bots when they're mentioned for similar reasons. If users really want to subscribe bots, they can do so explicitly.
These rules seem slightly like "bad implicit magic" since it's not immediately obvious why `@abc` subscribes that user but `@xyz` may not, but some of these rules are fairly complicated already (e.g., `@xyz` doesn't subscribe them if they unsubscribed or are implicitly subscribed) and this feels like it gets the right/desired result almost-always.
Test Plan:
On a fresh task:
- Mentioned a bot in a comment with `@bot`.
- Before patch: bot got CC'd.
- After patch: no CC.
- Called `maniphest.edit` via the API to add a comment as a bot.
- Before patch: bot got CC'd.
- After patch: no CC.

Depends on D20277. Ref T10333.
- Put profile icons on "Group by Owner".
- Add a similar "Group by Author". Probably not terribly useful, but cheap to implement now.
- Add "Sort by Title". Very likely not terribly useful, but cheap to implement and sort of flexible?

Summary:
Depends on D20276. Ref T10333. This one is a little bit rough/experimental, and I'm sort of curious what feedback we get about it. Weird stuff:
- All statuses are always shown, even if the filter prevents tasks in that status from appearing (which is the default, since views are "Open Tasks" by default).
- Pro: you can close tasks by dragging them to a closed status.
- Con: lots of empty groups.
- The "Duplicate" status is shown.
- Pro: Shows closed duplicate tasks.
- Con: Dragging tasks to "Duplicate" works, but is silly.
- Since boards show "open tasks" by default, dragging stuff to a closed status and then reloading the board causes it to vanish. This is kind of how everything works, but more obvious/defaulted on "Status".
These issues might overwhelm its usefulness, but there isn't much cost to nuking it in the future if feedback is mostly negative/confused.
Test Plan: Grouped a workboard by status, dragged stuff around.
