Summary:
Ref T8478. I think the cycle is:
- Conpherence Thread > Loads handle for participant > loads file for profile image > loads attached files to check visibility > loads conpherence thread > ...
So, specifically, someone attached their profile image to a thread or message somewhere.
This breaks the cycle by stopping the attached-files visibility check from happening, since we don't need it. This seemed like the easiest link in the chain to break.
//Ideally//, I think the longer-term and more complete fix here is to stop Conpherence from requiring handles in order to load thread handles (and, generally, having a "handles must not load other handles" rule), but that's not trivial and might not be especially practical.
Test Plan: Will test in production.

Summary:
Ref T4100. Ref T5595.
To support a unified "Projects:" query across all applications, a future diff is going to add a set of "Edge Logic" capabilities to `PolicyAwareQuery` which write the required SELECT, JOIN, WHERE, HAVING and GROUP clauses for you.
With the addition of "Edge Logic", we'll have three systems which may need to build components of query claues: ordering/paging, customfields/applicationsearch, and edge logic.
For most clauses, queries don't currently call into the parent explicitly to get default components. I want to move more query construction logic up the class tree so it can be shared.
For most methods, this isn't a problem, but many subclasses define a `buildWhereClause()`. Make all such definitions protected and consistent.
This causes no behavioral changes.
Test Plan: Ran `arc unit --everything`, which does a pretty through job of verifying this statically.

Ref T6013. Currently, when we create a thumbnail, it gets its own (default) file visibility policy.
In particular, this causes the issue in T6013: thumbnails get "all users" visibility, which does not include logged-out users.
Instead, a thumbnail should just have the same visibility as the original file does. Enforce this:
- When loading thumbnails, reject thumbnails with invisible originals.
- When filtering thumbnails, permit thumbnails with visible originals.
Test Plan: As a logged-out user, thumbnails are now visible when the original files are attached to visible objects.

Summary:
Ref T4589. When you look at a file, we load attached objects in order to run the "you can see this if you can see any attached object" policy check.
However, right now the subquery inherits the "throw on filter" flag from the parent query. This inheritance makes sense in other cases[1], but because this is an "ANY" rule it does not make sense here. In practice, it means that if the file is attached to several objects, and any of them gets filtered, you can not see the file.
Instead, explicitly drop the flag for this subquery.
[1] Sort of. It doesn't produce wrong results in other cases, but now that I think about it might produce a less-tailored error than it could. I'll look into this the next time I'm poking around.
Test Plan:
- Viewed an "All Users" file attached to a private Mock.
- Prior to this patch, I incorrectly received an exception when the Mock was loaded. This is wrong; I should be able to see the file because the policy is "All Users".
- After the patch, I can correctly view the file, just not the associated mock.

This provides a `phragment.getstate` and a `phragment.getpatch` Conduit method.
`phragment.getstate` - This returns the current state of the fragment and all of it's children.
`phragment.getpatch` - This accepts a base path and a mapping of paths to hashes. The mapping is for the caller to specify the current state of the files it has. This returns a list of patches that the caller needs to apply to it's files to get to the latest version.
Test Plan:
Ran the following script in a folder which had content matching a fragment and it's children:
```
#!/bin/bash
STATE=""
for i in $(find ./ -type f); do
HASH=$(cat $i | sha1sum | awk '{ print $1 }')

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.

Summary:
Ref T603. Several issues here:
1. Currently, `FileQuery` does not actually respect object attachment edges when doing policy checks. Everything else works fine, but this was missing an `array_keys()`.
2. Once that's fixed, we hit a bunch of recursion issues. For example, when loading a User we load the profile picture, and then that loads the User, and that loads the profile picture, etc.
3. Introduce a "Query Workspace", which holds objects we know we've loaded and know we can see but haven't finished filtering and/or attaching data to. This allows subqueries to look up objects instead of querying for them.
- We can probably generalize this a bit to make a few other queries more efficient. Pholio currently has a similar (but less general) "mock cache". However, it's keyed by ID instead of PHID so it's not easy to reuse this right now.
This is a bit complex for the problem being solved, but I think it's the cleanest approach and I believe the primitive will be useful in the future.
Test Plan: Looked at pastes, macros, mocks and projects as a logged-in and logged-out user.

Summary:
Ref T603. This uses the existing edges (from Conpherence) to record that a file is attached to an object, and uses those edges to create a policy exception: if you can view an attached object, you can view a file.
I'm going to combine this with restrictive defaults to satisfy the other half of the equation (that files you attach to a conpherence usually shouldn't be public by default).
Test Plan:
- Loaded `/files/`.
- Uploaded a file to a Conpherence, looked at it in Files, saw the attachment.

Summary:
Fixes T3143. When a user deletes a file, delete all transforms of the file too. In particular, this means that deleting an image deletes all the thumbnails of the image.
In most cases, this aligns with user expectations. The only sort of weird case I can come up with is that memes are transformations of the source macro image, so deleting grumpycat will delete all the hilarious grumpycat memes. This seems not-too-unreasonable, though, and desirable if someone accidentally uploads an inappropriate image which is promptly turned into a meme.
Test Plan:
Added a unit test which covers both inbound and outbound transformations.
Uploaded a file and deleted it, verified its thumbnail was also deleted.

Summary:
Fixes T3132. Currently, if a user deletes a file which is present in a mock, that mock throws an exception when loading. If the file is also the cover photo, the mock list throws an exception as well.
In other applications, we can sometimes deal with this (a sub-object vanishing) by implicitly hiding the parent object (for example, we can just vanish feed stories about objects which no longer exist). We can also sometimes deal with it by preventing sub-objects from being directly deleted.
However, neither approach is reasonable in this case.
If we vanish the whole mock, we'll lose all the comments and it will generally be weird. Vanishing a mock is a big deal compared to vanishing a feed story. We'll also need to load more data on the list view to prevent showing a mock on the list view and then realizing we need to vanish it on the detail view (because all of its images have been deleted).
We permit total deletion of files to allow users to recover from accidentally uploading sensitive files (which has happened a few times), and I'm hesitant to remove this capability because I think it serves a real need, so we can't prevent sub-objects from being deleted.
So we're left in a relatively unique situation. To solve this, I've added a "builtin" mechanism, which allows us to expose some resource we ship with as a PhabricatorFile. Then we just swap it out in place of the original file and proceed forward normally, as though nothing happened. The user sees a placeholder image instead of the original, but everything else works reasonably and this seems like a fairly acceptable outcome.
I believe we can use this mechanism to simplify some other code too, like default profile pictures.

- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
