The replacement, "diffusion.commit.search", is not really appropriate for low-level access. This mode of having a single method which operates in "cache" or "non-cache" modes also ends up in a lot of unnecessary field shuffling.

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.

- 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.

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.

- An author submits an urgent change for review.
- 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:
- As an author, used "Request Review" to promote a draft and to return a change to reviewers for consideration. These behaviors are unchanged, except "promote a draft" has different timeline text.

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.
