8ab8c390b7 If "branch" is provided to "diffusion.branchquery", use it as the "<pattern>" argument to "git branch --contains ..."
Summary:
Ref T13151. See PHI720. If you want to test if commit X appears on specific branch Y, `git branch --contains X -- Y` is faster than (effectively) `git branch --contains X | grep Y`.

Since this call has a "branch" parameter anyway, use it as the pattern argument if provided.

Test Plan:
  - Called the API method with no parameters, got all branches.
  - Called the API method with `master`, got just master.
  - Called the API method with `maste*`, got master. This behavior is not officially supported and may change in the future.
  - Viewed a commit, still saw all branches.
    - Grepped for `diffusion.branchquery` and verified that no remaining callsites pass a default "branch" parameter.

a7c681b549 Don't set mail HTML bodies if there's no actual HTML body
Summary:
See <https://discourse.phabricator-community.org/t/commit-6011085b0fcd-breaks-sending-certain-email/1571>. Some mailers get upset if we `setHTMLBody(...)` with an empty string.

1459fb3037 Make re-running rebuild-identities a bit faster and add a little progress information
Summary:
Ref T13151. Ref T12164. Two small tweaks:

  - If we aren't actually going to change anything, just skip the writes. This makes re-running/resuming a lot faster (~20x, locally).
  - Print when we touch a commit so there's some kind of visible status.

This is just a small quality-of-life tweak that I wrote anyway while investigating T13152, and will make finishing off db024, db025 and db010 manually a little easier.

Test Plan:
  - Set `authorIdentityPHID` + `committerIdentityPHID` to `NULL`.
  - Ran `rebuild-identities`, saw status information.
  - Ran `rebuild-identiites` again, saw it go faster with status information.

6011085b0f Respect "metamta.email-body-limit" when building mail HTML bodies
Summary:
Ref T13151. See T11767. See PHI686. Although we limit outbound mail text bodies, the limit doesn't currently apply to attachments, HTML bodies, or headers. T11767 discusses improving this in the general case.

In the wild, an install hit an issue (see PHI686) where edits to Phriction pages generate very large HTML bodies. Check and respect the limit when building HTML bodies.

If we don't have enough room for the HTML body, we just drop it. We have the text body to fall back to, and HTML is difficult to truncate safely.

c5b13a6be3 Allow object subtypes to be changed via bulk editor
Summary:
Ref T13151. See PHI683. Ref T12314.

You can currently change object subtypes via Conduit (`maniphest.edit`) but not via the web UI.

Changing object subtypes is inherently a somewhat-perilous operation that likely has a lot of rough edges we'll need to smooth over eventually, mostly around changing an object from subtype X to subtype Y, where some field exists on one but not the other. This isn't a huge issue, just not entirely intuitive.

It should also, in theory, be fairly rare.

As a reasonable middle ground, provide web UI access via the bulk editor. This makes it possible, but doesn't clutter the UI up with a rarely-used option with rough edges.

Test Plan:
  - With subtypes not configured, saw a normal bulk editor with no new option.
  - With subtypes configured, swapped tasks subtypes via bulk editor.

62a402491a Allow encrypted mail to be more specific about which object is affected
Summary:
Depends on D19487. Ref T13151. See PHI647. For some objects, like revisions, we can build slightly more useful secure email without actually disclosing anything.

In the general case, the object monogram may disclose information (`#acquire-competitor`) but most do not, so applications can whitelist an acceptable nondisclosing subject and link.

Support doing this, and make Differential do it. When we don't have a whitelisted URI but do know the object the mail is about, include a generic PHID-based URI; these are always nondisclosing.

Test Plan:
  - Without the Differential changes, sent normal mail (no changes) and secure mail (new generic PHID-based link).
  - With the Differential changes, sent secure mail; got richer subject and body link.

cbff913432 Add a "members of all projects" (vs "...any project") custom policy rule to the upstream
Summary:
Ref T13151. See PHI702. An install is interested in a "members of all projects" (vs "members of any project", which is currently implemented) rule.

Although this is fairly niche, I think it's reasonable and doesn't have much of a maintenance cost.

This could already be implemented as an extension, but it would have to copy/paste a bunch of code.

Test Plan:
  - Ran unit tests.
  - Used the UI to select this policy for a task, with various values. Joined/left projects to satisfy/fail the rule. Behavior seemed correct.
  - Used the UI to select the existing policy rule ("any project"), joined/left projects to satisfy/fail the rule. Doesn't look like I broke anything.

4e84d4d458 Allow the haunted comment panel ("Z") to take up more vertical room
Summary:
Ref T13151. See PHI685. When you haunt the panel, we only let it take up part of the screen. Let it take up slightly more of the screen so that it's more likely to fit completely on-screen without needing to scroll.

The behavior when it does scroll is fine (you get a scrollbar if your OS/browser is set up to show them) so this is a bit trivial/silly, but seems fine and doesn't have a big JS maintenance cost or anything.

7acda7e94e Truncate package names in diff table of contents views
Summary:
Ref T13151. See PHI654. Depends on D19477. If you have long package names, the table of contents (e.g., in Differential) can end up expanding to be gigantic.

Getting tables to behave nicely is hard (or, at least, I can't figure it out after spending a decent amount of time on it; see also `AphrontTableView::renderSingleDisplayLine()`). I tried a bunch of things and Googled for a bit but didn't make any progress on finding a CSS solution. Just truncate the package names to get reasonable behavior without falling down any kind of CSS rabbit hole.

Test Plan:
  - Created a package named "Very long package name...".
  - Created a package named "MMMMMMMMMMMMMMMMMMMMMM...".
  - Had them own a file in a Differential revision, viewed that revision.
  - Before: table is pushed out to several times the browser window width and everything is kind of a mess.
  - After: package names get truncated to something reasonable.

de999af614 Improve some behaviors around memory pressure when pushing many and/or large changes
Summary:
Ref T13142. When commits are pushed, we try to handle them on one of two pathways:

  - Normal changes: we load these into memory and potentially apply Herald content rules to them.
  - "Enormous" changes: we don't load these into memory and skip content rules for them.

The goal is to degrade gracefully when users push huge changes: they should work, just not support all the features.

However, some changes can slip through the cracks right now:

  - If you push a lot of commits at once, we'll try to cache all of the changes smaller than 1GB in memory. This can require an arbitrarily large amount of RAM.
  - We calculate sizes by just looking at the `strlen()` of the diff, but a changeset takes more RAM in PHP than the raw diff does. So even if a diff is "only" 500MB, it can take much more memory than that. On systems with relatively little memory available, this may result in OOM while processing changes that are close to the "enormous" limit.

This change makes two improvements:

  - Instead of caching everything, cache only 64MB of things.
    - For most pushes, this is the same, since they have less than 64MB of diffs.
    - For pushes of single very large changes, this is a bit slower (more CPU) since we have to do some work twice.
    - For pushes of many changes, this is slower (more CPU) since we have to do some work twice, but, critically, doesn't require unlimited memory.
  - Instead of flagging changes as "enormous" at 1GB, flag them as "enormous" at 256MB.
    - This reduces how much memory is required to process the largest "non-enormous" changes.
    - This also gets us under Git's hard-coded 512MB "always binary" cutoff; see T13143.
    - This is still completely gigantic and way larger than any normal change should be.

An additional improvement would be to try to reduce the amount of memory we need to use to hold a change in process memory. I think the other changes here alone will fix the immediate issue in PHI657, but it would be nice if the "largest non-enormous change" required only a couple gigs of RAM.

Test Plan:
- Used `ini_set('memory_limit', '1G')` to artificially limit memory to 1GB.
- Pushed a series of two commits which add two 550MB text files (Temporarily, I added a `--binary` flag to trick Git into showing real diffs for these, see T13143.)
- Got a memory limit error.
- Applied the "cache only 64MB of stuff" and "consider 256MB, not 1GB, to be enormous" changes.
- Pushed again, got properly rejected as enormous.
- Added `memory_get_usage()` calls to measure how actual memory size and reported "size" estimate compare. For these changes, saw a 639MB diff require 31,479MB of memory, i.e. a factor of about 50x. This is, uh, pretty not great.
- Allowed enormous changes, pushed again, push went through.

Ref T13141. Currently, during first-time setup we don't surface all the details about connection exceptions that we could: the underlying exception is discarded inside cluster connection management.

Instead, store the original exception and propagate the message up the stack so users have more information about the problem.

79fdf5c127 Separate changeset analysis code from DifferentialDiff and provide a standalone rebuild-changesets workflow
Summary:
Ref T13137. The "analyze/cache data about changesets" step is becoming more involved. We recently added detection for generated code to support "Ignore generated changes" in Owners, and I now plan to hash the new file content so we can hide changes which have no effect.

Before adding this new hashing step, pull the "detect copied code" and "detect generated code" stuff out and move them to a separate `ChangesetEngine`. Then support doing a changeset rebuild directly with `bin/differential rebuild-changesets`.

This simplifies things a bit and makes testing easier since you don't need to keep creating new revisions to re-run copy/generated/hash logic.

Test Plan: Ran `bin/differential rebuild-changesets --revision Dxxx`, saw changesets rebuild. See also next change.

3544620209 Parse unusual Subversion protocol frames which contain extra whitespace
Summary:
Fixes T13140. See PHI660.

Recent versions of Subversion can send a `(get-file true false  false )` protocol frame with extra space between "false" and "false". This is allowed by the protocol spec, but never normally happens, and we do not parse it correctly.

Instead, parse it correctly.

Test Plan:
  - Added unit tests.
  - Ran `svn proplist svn+ssh://.../diffusion/X/file.c` under SVN 1.10 before and after the change.
    - Before: indefinite hang.
    - After: completed in finite time.

7aa12f192a Add PhabricatorQueryIterator, for buffered iteration over a CursorPagedPolicyAwareQuery
Summary:
See D19446. This should make it easier to process larger, more complex result sets in constant memory.

Today, `LiskMigrationIterator` takes constant memory but can't apply `needX()` reqeusts or `withY(...)` constraints.

Using a raw `Query` can handle this stuff, but requires memory proportional to the size of the result set.

Offer the best of both worlds: constant memory and full access to the power of `Query` classes.

Test Plan:
Used this script to iterate over every commit, saw sensible behavior:

```name=list-commits.php
<?php

require_once 'scripts/init/init-script.php';

$viewer = PhabricatorUser::getOmnipotentUser();

$query = id(new DiffusionCommitQuery())
  ->setViewer($viewer);

$iterator = new PhabricatorQueryIterator($query);
foreach ($iterator as $commit) {
  echo $commit->getID()."\n";
}
```

28ee6b8080 Consistently require MFA on the actual user creation flow
Summary:
See <https://hackerone.com/reports/351361>. We currently require MFA on the screen leading into the user create flow, but not the actual create flow.

That is, `/people/create/` (which is just a "choose a type of account" page) requires MFA, but `/people/new/<type>/` does not, even though this is the actual creation page.

Requiring MFA to create users isn't especially critical: creating users isn't really a dangerous action. The major threat is probably just that an attacker can extend their access to an install by creating an account which they have credentials for.

It also isn't consistently enforced: you can invite users or approve users without an MFA check.

So there's an argument for just removing the check. However, I think the check is probably reasonable and that we'd likely prefer to add some more checks eventually (e.g., require MFA to approve or invite) since these actions are rare and could represent useful tools for an attacker even if they are not especially dangerous on their own. This is also the only way to create bot or mailing list accounts, so this check does //something// on its own, at least.

Test Plan:
  - Visited `/people/new/standard/` as an admin with MFA configured.
  - Before patch: no MFA prompt.
  - After patch: MFA prompt.

26d0862f4f Apply the new patch byte size limit to mail patch generation in Differential
Summary: Ref T13137. See PHI592. Depends on D19444. Apply a limit up front to stop patches which are way too big (e.g., 600MB of videos) from generating in the first place.

Test Plan:
  - Configured inline patches in git format.
  - Created a normal revision, got an inline git patch.
  - Created a revision with a 10MB video file, got no inline patch.
  - (Added a bunch of debugging stuff to make sure the internal pathway was working.)

10a4b05ecb Fix "Any Owner" and "No Owners" searches in Maniphest
Summary:
See <https://discourse.phabricator-community.org/t/maniphest-home-page-crash-after-d19417/1445/3>. These special-token-only searches currently end up populating an empty `ownerPHIDs`, which fatals after the stricter check in D19417.

Make the fatal on `withConstraint(array())` explicit and only set the PHID constraint if we have some PHIDs left.

d280b24239 Fix "arc paste" to stop creating pastes with an empty string ("") as the "language"
Summary:
See PHI652. When you `echo x | arc paste` today, you end up with a Paste object that has the empty string as its "language".

This is normally not valid. Pastes where the language should be autodetected should have the value `null`, not the empty string.

This behavior likely changed when `paste.create` got rewritten in terms of `paste.edit`. Adjust the implementation so it only adds the LANGUAGE transaction if there's an actual language.

Also, fix an issue where you can't use the "delete" key to delete tokens with the empty string as their value.

Test Plan:
  - Created a paste with `echo x | arc paste`, got a paste in autodetect mode instead of with a bogus language value.
  - Created a paste with `echo x | arc paste --lang rainbow`, got a rainbow paste.
  - Deleted an empty string token with the keyboard.
  - Deleted normal tokens with the keyboard.
  - Edited subscribers/etc normally with the keyboard and mouse to make sure I didn't ruin anything.

26c0db8dd7 Allow navigation breadcrumbs to be marked as "always visible" so they show up on phones
Summary:
See PHI624. Some of the mobile navigation and breadcrumbs in support pacts aren't as good as they could be.

In particular, we generally collapse crumbs on mobile to just the first and last crumbs. The first crumb is the application; the last is the current page.

On `/PHIxxx` pages, the first crumb isn't very useful since the Support landing page is two levels up: you usually want to go back to the pact, not all the way back to the Support landing page.

We also don't need the space since the last crumb (`PHIxxx`) is always small.

Allow Support and other similar applications to tailor the crumb behavior more narrowly if they end up in situations like this.

Test Plan:
  - With an additional change to instances (see next diff), viewed a support issue page (`/PHI123`) on mobile and desktop.
  - Saw a link directly back to the pact on both mobile and desktop.

5b640a434c Support an "Ancestors Of: ..." constraint in commit queries
Summary:
Ref T13137. See PHI609. An install would like to filter audit requests on a particular branch, e.g. "master".

This is difficult in the general case because we can not apply this constraint efficiently under every conceivable data shape, but we can do a reasonable job in most practical cases.

See T13137#238822 for more detailed discussion on the approach here.

This is a bit rough, but should do the job for now.

Test Plan:
- Filtered commits by various branches, e.g. "master"; "lfs". Saw correct-seeming results.
- Stubbed out the "just list everything" path to hit the `diffusion.internal.ancestors` path, saw the same correct-seeming results.

  - Exported to text, JSON, XLS.
  - Saw 6.25 represented accurately in exports.
  - Exported an excel sheet with 27+ columns.

4a98e0ff65 Allow Owners packages to be configured to ignore generated paths in Differential
Summary:
Depends on D19427. Ref T13130. See PHI251. Support configuring owners packages so they ignore generated paths.

This is still a little rough. A couple limitations:

  - It's hard to figure out how to use this control if you don't know what it's for, but we don't currently have a "CheckboxesEditField". I may add that soon.
  - The attribute ignore list doesn't apply to Diffusion, only Differential, which isn't obvious. I'll either try to make it work in Diffusion or note this somewhere.
  - No documentation yet (which could mitigate the other two issues a bit).

But the actual behavior seems to work fine.

Test Plan:
  - Set a package to ignore paths with the "generated" attribute. Saw the package stop matching generated paths in Differential.
  - Removed the attribute from the ignore list.
  - Tried to set invalid attributes, got sensible errors.
  - Queried a package with Conduit, got the ignored attribute list.

Depends on D19425. Ref T13130. See PHI251. Now that changesets have a durable "generated" attribute, we can let owners packages check it when we're computing which packages are affected by a revision.

    - When I faked `mustMatchUngeneratedPaths()` to `return true;`, saw the non-generated file get no packages owning it.
    - Normally: lots of packages owning it).
  - Created a revision affecting only generated files.
    - When I faked things, saw no Owners actions trigger.
    - Normally: some packages added reviewers or subscribers.
