57f9450bcf Improve desktop and mobile layouts for new "CommitGridView"
Summary:
Ref T13552. The current layout doesn't work particularly well on desktops or devices.

We have some device/desktop table layout code, but it isn't generic. We also have property list layout code, but it isn't generic either.

Provide generic layout elements ("Fuel", from "Phabricator UI Layout" to "PHUIL"?) and narrowly specialize their display behavior. Then swap the ListItemView stuff to use it.

Test Plan:
Saw slightly better responsive behavior:

46695c76eb Introduce "DiffusionCommitGraphView", which unifies "HistoryListView" and "HistoryTableView"
Summary:
Ref T13552. Currently, commit lists are sometimes rendered as an object list and sometimes rendered as a table. There are two separate views for table rendering.

Add a fourth view ("list, with a graph") with the eventual intent of unifying all the other views. For now, this only replaces "HistoryListView" -- and needs some more work to really be a convincing replacement.

60e9f64190 Remove the "authored" subheader from commits
Summary:
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.

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.

ce0dc9a2ba Correct an apparent off-by-one error when adjusting inlines across revision changes
Summary:
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.

  - 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.

dbdfac1e07 Recover inline comments which are "adjusted" off the end of a diff
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.

2db1955159 In Jupyter notebooks, read strings stored in the raw as either "string" or "list<string>" more consistently
Summary:
Ref PHI1835. Generally, Jupyter notebooks in the wild may store source and markdown content as either a single string or a list of strings.

This also fixes an issue where cell labels were double-rendered in diff views.

c1eeacd850 Move "Wait for Previous Commits to Build" out of prototype
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.

017ef1927c Revert use of "user-select: all" to modify tab selection behavior
Summary:
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.

78d1b62bb8 Streamline handling of Futures and PIDs in daemons
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.
  - Ran daemons with intentional resolution exceptions, saw clean recovery.

fcb75d0503 Fix an issue where prose diffing may fail after hitting the PCRE backtracking limit
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.

37ffb71c4d In source views, wrap display tabs in "user-select: all" to improve cursor selection behavior
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.

1d4d860cb5 Allow non-authors to "Request Review" of draft revisions
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.

56838c0e3d Fix an issue where querying for a large number of projects by slug could paginate incorrectly
Summary:
See PHI1809. This query may join the "slug" table, but each project may have multiple slugs, and the query does not "GROUP BY" when this join occurs.

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.

Test Plan:
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.
  - Actual: P generates 3 raw rows and the final result is just P with no pagination cursor.

A handful of Phacility production shards have run into memory pressure issues recently.

Ref PHI1798. If you put an SSH public key in a table cell with monospaced formatting and then print the table, the cell scrolls and not all of the content appears in your physical printed document.

22de618d3b When acquiring a GlobalLock, put good connections that just got unlucky back in the pool
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.

d91abf50f7 Add "--background" and "--count" flags to "bin/webhook call"
Summary:
See PHI1794, which reports an issue where a large number of queued webhook calls led to connection exhaustion. To make this easier to reproduce and test, add "--count" and "--background" flags to "bin/webhook call".

This primarily supports "bin/webook call ... --background --count 10000" to quickly fill the queue with a bunch of calls.

Test Plan: Ran `bin/webhook call` in foreground and background modes, with and without counts. Saw appropriate console and queue behavior.

9ce1271805 Improve the quality of SSH error messages
Summary: See PHI1784. Currently, users who pass an invalid SSH command to Phabricator's SSH handler get an unhelpful error message. Make it more helpful.

Test Plan: Ran `./bin/ssh-exec` with no arguments (old, helpful error), invalid arguments (before: unhelpful error; after: helpful error), and valid arguments (old, helpful behavior).

8c7f114b4d Fix an issue where "Export Data" could fail if a user had a nonempty custom policy preference
Summary:
The "Export Data" workflow incorrectly uses the "Policy Favorites" setting to choose a default export format. This is just a copy/paste error; the correct setting exists and is unused.

If the setting value is an array (as the "Policy Favorites" value often is), we try to use it as an array index. This generates a runtime exception after D21044.

```
[2020-06-16 06:32:12] EXCEPTION: (RuntimeException) Illegal offset type in isset or empty at [<arcanist>/src/error/PhutilErrorHandler.php:263]
  #0 <#2> PhutilErrorHandler::handleError(integer, string, string, integer, array) called at [<phabricator>/src/applications/search/controller/PhabricatorApplicationSearchController.php:460]
```

  - Use the correct setting.
  - Make sure the value we read is a string.

Test Plan:
  - Used "Export Data" with a nonempty, array-valued "Policy Favorites" setting.
    - Before: runtime exception.
    - After: clean export.
  - Used "Export Data" again, saw my selection from the first time persisted.

5b1dd96e40 Add an explicit "uri" to the "harbormaster.buildable.search" results
Summary: Ref T13546. This makes some "arc" tasks a little easier, and will make them more correct if "arc" ever switches to using SSH.

Test Plan: Ran "harbormaster.buildable.search" from the web UI, saw URIs in the result set.

36075f6ce5 Correct a prose diff behavior when prose pieces include newlines
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.

f686a0b827 In Phortune accounts, prevent self-removal more narrowly
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.

a529efa5b8 Fix an issue where inline comments with only edit suggestions are considered empty
Summary:
Ref T13513. An inline is not considered empty if it has a suggestion, but some of the shared transaction code doesn't test for this properly.

Update the shared transaction code to be aware that application comments may have more complex emptiness rules.

Test Plan:
  - Posted an inline with only an edit suggestion, comment went through.
  - Tried to post a normal empty comment, got an appropriate warning.

959a835b95 When executing a repository passthru command via CommandEngine, don't set a timeout
Summary:
Ref T13541. The passthru future does not have time limit behavior, so if we reach this code we currently fail.

Phabricator never reaches this code normally, but this code is reachable during debugging if you try to foreground a slow fetch to inspect it.

Passthru commands generally only make sense to run interactively, and the caller or control script can enforce their own timeouts (usually by pressing "^C" with their fingers).

Test Plan: Used a debugging script to run ref-by-ref fetches in the foreground.
