Ref T13627. Currently, global locks always return connections (even external connections) to the connection pool when unlocked.
This code is obviously buggy: `isExternalConnection` is set to false immediately before it is tested. This bug has existed since this code was introduced, in D15792.

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.
- Commented out a couple of caches, and used `bin/repository reparse --publish ...` to republish the commit.
- Before: exception when trying to interact with the API.

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.
- Applied the "limit 1" part of the change, got a second page of notifications.

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.

Differential Revision: https://secure.phabricator.com/D21516
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.

Ref T13552. I'm trying to reduce the number of direct callers to commit authorship metadata. This header seems low-value enough to simply remove; this information is shown more clearly and prominently in the "Provenance" UI.
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. And it potentially uses an "Identity" as a timeline actor, which is conceptually fine but not entirely firm ground.
Test Plan: Viewed a commit, saw no more subheader.

Ref T13552. When viewing a directory in Diffusion, we make an Ajax call to get the last commit for each path.
This call currently pulls author information, since an older version of this UI showed author information.
The current UI does not show author information, so this parameter is unused. Delete the code which builds it.
Test Plan: Grepped for `'author'` and references to the "pull-lastmodified" behavior. This behavior is invoked in only one place, which never generates an author placeholder.

See PHI1834. It's not obvious why this "+1" is present in the code, but it causes inlines to be adjusted incorrectly when a file is not modified across changes. See D21435.
Remove it, which appears to produce accurate adjustment behavior.
Test Plan:
- See D21435 for instructions to build a change, where a file with lines "A-Z" is unmodified across Diff 1 and Diff 2.
- 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.
- After: saw inlines correctly adjusted to lines 14, 17, and 16 (the same lines as the original), render properly, and highlight the correct lines when hovered.

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.
- After: comment is still adjusted out of range internally, but now corrected into the display range and shown.

Summary:
Although I'm not entirely thrilled about doing flow control like this (as an actual action in a build plan), I believe this build step works correctly and there's no fancy replacement mechanism on the immediate horizon, and this didn't send us down a slippery slope of Turing-complete builds encoded without real structure or context. Just kick it out of prototype.
(Other approaches which might be better in the long run are things like "this is a top-level behavior on the build plan itself" and/or "build plans are written in a DSL, not a Javascript UI".)
Test Plan: Added a new build step, saw this as an option in the "Flow Control" section.

Reverts D21419. See PHI1814. Previously, I used "user-select: all" to group sequences of spaces for selection.
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.
This behavior is enough of a net negative that I think we're in a worse state overall; revert it.

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.

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.

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.

Summary:
See PHI1810. In situations where:
- 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.
- As a non-author, used "Begin Review" to promote a draft.

Narrow the scope of the warning so it is raised only if you're adding a subscriber other than yourself.

This may lead to partial result sets and unusual paging behavior.
This could likely be caught categorically in `loadAllFromArray()`; I'll adjust this in a followup.

A minimal reproduction case is something like:
- Give project P slugs: a, b, c.
- Give project Q slugs: d.
- Query for slugs: a, b, c, d; with limit 2.
- Order the query so P returns first.
- Expect: P and Q.

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.

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.

Summary:
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.
Test Plan: Elsewhere, ran staff tooling to modify accounts and was able to act as "alice" to add "bailey", even though "alice" was not herself a manager.
