0a76d82a7c Use string constants, not integer constants, to represent task status internally
Summary:
Ref T1812. I think integer constants are going to be confusing and error prone for users to interact with. For example, because we use 0-5, adding a second "open" status like "needs verification" without disrupting the existing statuses would require users to define a status with, e.g., constant `6`, but order it between constants `0` and `1`. And if they later remove statuses, they need to avoid reusing existing constants.

Instead, use more manageable string constants like "open", "resolved", etc.

We must migrate three tables:

  - The task table itself, to update task status.
  - The transaction table, to update historic status changes.
  - The saved query table, to update saved queries which specify status sets.

Test Plan:
  - Saved a query with complicated status filters.
  - Ran migrations.
  - Looked at the query, at existing tasks, and at task transactions.
  - Forced migrations to run again to verify idempotentcy/safety.

a48128d36f Partially use ApplicationSearch in main search
Summary:
Ref T4365. Primary search currently uses `PhabricatorSearchQuery` for storage, which is pretty much the same as `PhabricatorSavedQuery`, except that it's old and not used anywhere else anymore.

Maniphest used to also use this table, but no longer does after Septmeber, 2013. We need to retain the class so the migration can work.

This introduces `PhabricatorSearchApplicationSearchEngine` and `PhabricatorSearchDocumentQuery`, but they're both stubs that I just needed for technical reasons and/or to pass lint. The next couple patches will move logic into them and use ApplicationSearch properly.

Test Plan:
  - Searched for stuff.
  - Searched for stuff with filters.
  - Searched for fulltext in Maniphest.
  - Grepped for `PhabricatorSearchQuery`.

2a5c987c71 Lock policy queries to their applications
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.

7abe9dc4c0 Migrate all Maniphest transaction data to new storage
Summary:
Ref T2217. This is the risky, hard part; everything after this should be smooth sailing. This is //mostly// clean, except:

  - The old format would opportunistically combine a comment with some other transaction type if it could. We no longer do that, so:
    - When migrating, "edit" + "comment" transactions need to be split in two.
    - When editing now, we should no longer combine these transaction types.
    - These changes are pretty straightforward and low-impact.
  - This migration promotes "auxiliary field" data to the new CustomField/StandardField format, so that's not a straight migration either. The formats are very similar, though.

Broadly, this takes the same attack that the auth migration did: proxy all the code through to the new storage. `ManiphestTransaction` is now just an API on top of `ManiphestTransactionPro`, which is the new storage format. The two formats are very similar, so this was mostly a straight copy from one table to the other.

Test Plan:
  - Without performing the migration, made a bunch of edits and comments on tasks and verified the new code works correctly.
  - Droped the test data and performed the migration.
  - Looked at the resulting data for obvious discrepancies.
  - Looked at a bunch of tasks and their transaction history.
  - Used Conduit to pull transaction data.
  - Edited task description and clicked "View Details" on transaction.
  - Used batch editor.
  - Made a bunch more edits.

17e1732152 Route all ManiphestTransaction reads through a single class
Summary:
Ref T2217. I'm going to do the fake-double-writes ("double reads"?) thing where we proxy the storage that worked pretty well for auth. That is:

  - (Some more cleanup diffs next, maybe?)
  - Move all the data to the new storage, and make `ManiphestTransaction` read and write by wrapping `ManiphestTransactionPro`.
  - If nothing breaks, it's a straight shot to nuking ManiphestTransaction callsite by callsite.

I think Maniphest is way easier than Differential, because there are very few query sites and no inline comments.

Test Plan: `grep` to find callsites. Loaded task view, called Conduit.

e7a7e43104 Fix a bug where policy queries with cursor-based pagers and non-ID orders can go into infinite loops
Summary:
Ref T603. See inlines for an explanation. The case where I hit this was loading the "Pending Differential Revisions" panel in Diffusion when logged out, after making a repository public.

What happens is that we load 10 revisions (say, D1 .. D10) but the user can't see any of them. We then try to load the next 10, but since the pagination is ordered by date modified, we need to base the next query on the modified date of the last thing we loaded (D10). However, since we use the viewer's policies to load that cursor object, it fails to load, and then we just issue the same query over and over again, loading D1 .. D10 until we run out of execution time.

Test Plan: Interface now loads correctly.

a82c3a8914 Allow Maniphest queries to have configurable page sizes
Summary:
Current page size is `1000`. This is nice to have in some cases, but makes pages slower than necessary in others. Task lists are generally dominated by rendering costs.

For example, my default is "recent tasks", which just lists all tasks ordered by date created. Showing 100 tasks here instead of 1000 makes this several times faster without compromising utility.

I don't want to force the default to 100, though, since sometimes listing everything is quite useful and I think an advantage of Maniphest is that it generally deals reasonably well with large task sets.

(This `limit` property is actually read by the default implementation of `getPageSize()` in the parent class.)

Test Plan: Made queries with page sizes 1, 100, 12, 9, 3000, etc.

e7853e4801 Allow tasks to be subprioritized by drag-and-drop
Summary:
Like the title says, similar to Facebook Tasks.

Not sure how I really feel about this, but I guess it's kind of OK? I never used
this feature in Facebook Tasks but I think some people like it.

The drag-and-drop to repri across priorities feels okayish.

Because subpriority is a double and we just split the difference when
reprioritizing, you lose ~a bit of precision every time you repri two tasks
against each other and so you can break it by swapping the priorities of two
tasks ~50 times. This case is pretty silly and pathological. We can add some
code to deal with this at some point if necessary.

I think this also fixes the whacky task layout widths once and for all.

(There are a couple of minor UI glitches like headers not vanishing and header
counts not updating that I'm not fixing because I am lazy.)

Test Plan: Dragged and dropped tasks around.

afed8bb929 Add "Group by: Project" to Maniphest
Summary:
Allow tasks to be grouped by project. Since this is many-to-many and we're a little deficient on indexes for doing this on the database, we pull all matching tasks and group them in PHP. This shouldn't be a huge issue for any existing installs, though, and we can add keys when we run into one.

  - When a task is in multiple projects, it appears under multiple headers.
  - When a query has a task filter, those projects are omitted from the grouping (they'd always show everything, which isn't useful). Notably, if you search for "Differential", you can now see "Bugs", "Feature Requests", etc.

Test Plan: Selected "Group by: Project".

Test Plan: Looked at project list, clicked open tasks link

49310391e0 Added subscriber view to Maniphest.
Summary:
People want to see all the tasks they have subscribed to in one
view. A new table was added for this to make queries faster.

Test Plan:
Tested that the view was initially empty. After running the
reindex_maniphest.php script, I saw the correct tasks there. Added
myself as a subscriber to one task and made sure the view was
updated. Removed myself as a subscriber from one task and made sure
the view was updated again.

de0c89261e Allow Maniphest tasks to be filtered by Project
Summary:
Major things taking place here:

  - A new table for storing <task, project> relationships.
  - Moved all task query logic into a dedicated class.
  - Added a "projects" filter to the UI.

I was originally going to try to drive this off the main search index but the
perf benefits of a custom schema make an overwhelming argument in favor of doing
it this way.

Test Plan:
Filtered tasks by author and owner and zero, one, and more than one project.
Exercised all the group/sort options. Ran the index script over my 100k task
corpus. Edited task-project membership and verified the index updated.
