Summary:
See PHI985. I think we pretty much need to start applying language-specific rules, but we can apply at least one more relatively language-agnostic rule: don't match lines which are indented 3+ levels.
In C++, we may have symbols like this:
```
class X {
public:
int m() { ... }
}
```
..but I believe no mainstream language puts symbol definitions 3+ levels deep.
Also clean up some of the tab handling very slightly.
Test Plan: Tests pass, looked at some C++ code and got slightly better (but still not great) matches.

Depends on D20462. Ref T13276. Currently, the "Message" parser also updates related tasks and revisions when a commit is published.
For PHI1165, which ran into a race with message parsing, I originally believed we needed to separate this logic and lock + yield to avoid the race. D20462 provides what is probably a better approach for avoiding the race.
Still, I think separating these "update related revisions" and "updated related tasks" chunks into separate workers is a net improvement. There may still be some value in doing lock + yield in the future to deal with other issues, and when we occasionally run into problems with pulling a diff out of the repository to update the revision (usually because the diff is too big) this isolates the problem better and allows the commit to import.
I think the only thing to watch out for here is that Herald may now run before the revision and commit are attached to one another. This is fine for all current Herald rules, we just need to be mindful in implementing new rules.

Summary:
Depends on D20461. Ref T13276. Ref T13054.
Currently, we acquire the transaction read lock after populating "old values" in transactions and filtering transactions with no effect.
This isn't early enough to prevent all weird chaotic races: if two processes try to apply a "close revision" transaction at the same time, this can happen:
```
PROCESS A PROCESS B
Old Value = Open Old Value = Open
Transaction OK: Yes Transaction OK: Yes
Acquire Read Lock Acquire Read Lock
Got Read Lock! Wait...
Apply Transactions Wait...
New Value = Closed Wait...
Release Lock Wait...
Got Read Lock!
Apply Transactions
New Value = Closed
Release Lock
```
That's not great: both processes apply an "Open -> Closed" transaction since this was a valid transaction from the viewpoint of each process when it did the checks.
We actually want this:
```
PROCESS A PROCESS B
Acquire Read Lock Acquire Read Lock
Got Read Lock! Wait...
Old Value = Open Wait...
Transaction OK: Yes Wait...
Apply Transactions Wait...
New Value = Closed Wait...
Release Lock Wait...
Got Read Lock!
>>> Old Value = Closed
>>> Transaction Has No Effect!
>>> Do Nothing / Abort
Release Lock
```
Move the "lock" part up so we do that.
This may cause some kind of weird second-order effects, but T13054 went through pretty cleanly and we have to do this to get correct behavior, so we can survive those if/when they arise.
Test Plan:
- Added a `sleep(10)` before the lock.
- Ran `bin/repository message --reparse X` in two console windows, where X is a commit that closes revision Y and Y is open.
- Before patch: both windows closed the revision and added duplicate transactions.
- After patch: only one of the processes had an effect.

Summary:
Depends on D20445. Ref T13279. I'm not sure what the class tree of functions actually looks like, and I suspect it isn't really a tree, so I'm hesitant to start subclassing. Instead, try adding some `isSomethingSomething()` methods.
We have some different types of functions:
# Some functions can be evaluated anywhere, like "constant(3)", which always evaluates to 3.
# Some functions can't be evaluated anywhere, but have values everywhere in some domain. This is most interesting functions, like "number of open tasks". These functions also usually have a distinct set of interesting points, and are constant between those points (any count of anything, like "open points in project" or "tasks closed by alice", etc).
# Some functions can be evaluated almost nowhere and have only discrete values. This is most of the data we actually store, which is just "+1" when a task is opened and "-1" when a task is closed.
Soon, I'd like to be able to show ("all tasks" - "open tasks") and draw a chart of closed tasks. This is somewhat tricky because the two datasets are of the second class of function (straight lines connecting dots) but their "interesting" x values won't be the same (users don't open and close tasks every second, or at the same time).
The "subtract X Y" function will need to be able to know that `subtract "all tasks" 3` and `subtract "all tasks" "closed tasks"` evaluate slightly differently.
To make this worse, the data we actually //store// is of the third class of function (just the "derivative" of the line chart), then we accumulate it in the application after we pull it out of the database. So the code will need to know that `subtract "derivative of all tasks" "derivative of closed tasks"` is meaningless, or the UI needs to make that clear, or it needs to interpret it to mean "accumulate the derivative into a line first".
Anyway, I'll sort that out in future changes. For now, simplify the easy case of functions in class (1), where they're just actual functions.
Add "shift(function, number)" and "scale(function, number)". These are probably like "mul" and "add" but they can't take two functions -- the second value must always be a constant. Maybe these will go away in the future and become `add(function, constant(3))` or something?

Also, remove some code which examines branches and tags in a special way for non-bare working copies. The old `git fetch <origin>` code without explicit revsets meant that `refs/remotes/orgin/heads/xyz` got updated instead of `refs/heads/xyz`. We now update our local refs in all cases (bare and non-bare) so we can throw away this special casing.

The range of the chart is locked to "[0, 105% of max]". This is trying to make a pleasing extra margin above the maximum value, but currently just breaks charts with negative values. Later:
- I'll probably let users customize this.
- We should likely select 0 as the automatic minimum for charts with no negative values.
- For charts with positive values, it would be nice to automatically pick a pleasantly round number (25, 100, 1000) as a maximum by default.
We don't have any storage for charts yet. Add some. This works like queries, where every possible configuration gets a short URL slug. Nothing writes or reads this yet.
Rename `fn()` to `css_function()`. This builds CSS functions for D3. The JS is likely to get substantial structural rewrites later on, `fn()` was just particularly offensive.

This fixes the warning, and also means that `git clone` will check out the repository default branch by default, which is nice.
There are a few caveats about this behavior (see T5963 for discussion) but nothing too substantial.

Depends on D20421. Ref T13277. I'd generally like to move away from "Track Only".
Some of the use cases for "Track Only" (or adjacent to "Track Only") are better resolved with "Fetch Rules" -- basically, rules to fetch only some subset of refs from the observed remote.
Add configurable "Fetch Rules" for Git repositories. For example, if you only want to fetch `master`, you can now speify:
```
refs/heads/master
```
If you only want to fetch branches and tags, you can use:
```
refs/heads/*
refs/tags/*

In theory, this is slightly less powerful in the general case than "Track Only", but gives us better behavior in some cases (e.g., when the remote has 50K random temporary branches). In practice, I think this and a better "Autoclose Only" will let us move away from "Track Only", get default behavior which is better aligned with what users actually expect, and dodge all the "track tags/refs" questions.
Test Plan: Configured repositories with "Fetch Refs" rules, used `bin/repository pull --verbose --trace ...` to run pulls, saw expected pull/fetch behavior.

Summary:
Depends on D20420. Ref T13277. We currently spend substantial effort trying to detect and correct the URL of the "origin" remote in Git repositories.
I believe this is unnecessary, and we can always `git fetch <url> ...` to get the desired result instead of `git muck-with-origin + git fetch origin ...`. We already do this in the more recent parts of the codebase (e.g., intracluster sync) and it works correctly in every case I'm aware of.
Test Plan:
- Grepped for `origin`, ` origin `.
- Ran `bin/repository update ...` to fetch a mirrored repository.

Summary:
Depends on D20418. Ref T13277. Fixes T11314.
Currently, when you push commits to some arbitrary ref or tag (like `refs/pull/123` on GitHub, `refs/tags/phabricator/diff/123` on Phabricator, or `refs/changes/whatever` on Gerrit), we do not "autoclose" related objects. This means that we don't process `Ref T123` to create links to tasks, and don't process `Differential Revision: xyz` to close revisions.
However, we //do// still publish these commits. "Publish" means: trigger audits, publish feed stories, and run Herald rules.
- Stop publishing these commits.
- In the UI, show these commits as "Not Permanent" with a note that they are "Not [on any permanent branch]."
These commits will publish and autoclose if they ever become reachable from an "autoclose" ref (most commonly, if they are later merged to "master").
Test Plan:
- Pushed a commit to `refs/tags/quack`.
- Before: got a feed story.
- After: no feed story, UI shows commit as "Not Permanent".

Summary:
Depends on D20381. Ref T8093. This makes minor improvements to the protocol proxy to handle cases where we add, remove, or replace refs and may need to move the "capabilities" section.
Rather than invoking a callback on every ref: parse the whole ref list into a data structure, mutate it if necessary (in a future diff), then dump it back into wire format.
This allows us to shift the capabilities data (which needs to be coupled with the first ref) around if we modify the first ref, and reorder the reflist alphabetically like git does.
When the server has no refs, Git sends no capabilities data. This is easy to emulate, just surprising.
Test Plan:
Tested the cases not covered by D20381:
- Fetching where the fetch actually fetches data.
- `ls-remote` when we hide the first ref (capabilities data properly moves to the first visible ref).
- `ls-remote` when the remote is empty (we just drop the capabilities frame completely).

Summary:
Depends on D20380. Ref T8093. When prototypes are enabled, inject a (hopefully?) no-op proxy into the Git wire protocol.
This proxy decodes "git upload-pack" and allows the list of references to be rewritten, in a similar way to how we already proxy the Subversion protocol to rewrite URIs and proxy the Mercurial protocol to distinguish between read and write operations.
The piece we care about comes at the beginning, and looks like this:
```
<frame-length><ref-hash> <ref-name>\0<server-capabilities>\n
<frame-length><ref-hash> <ref-name>\n
<frame-length><ref-hash> <ref-name>\n
...
<0000>
```
We can add, remove, or modify this section to make it appear that the server has different refs than the refs that exist on disk.
Things I have tried:
- `git ls-remote`
- `git ls-remote` where the server hides some refs.
- `git fetch` where the fetch is a no-op.
Things I have not tried:
- `git fetch` where the fetch is not a no-op.
- Tricking things into doing protocol v2. Or: I tried this, I wasn't successful. In v2, additional "\0" tricks are used to hide data in the capabilities, I think?
- `git ls-remote` where we rewrite/hide the first ref in the list, and need to move the capabilities frame elsewhere.
- `git ls-remote` where the server has no refs at all, or we remove every ref.
So the "interesting" piece of this works, but it almost certainly needs some cleanup to survive interaction with the real world.
Test Plan: See above.

Ref T8093. Support dumping the protocol bytes to a side channel logfile, as a precursor to parsing the protocol and rewriting protocol frames to virtualize refs.
The protocol itself is mostly ASCII text so the raw protocol bytes are pretty comprehensible.

Summary:
See PHI1134. Generally, "alice added a dependent revision: ..." isn't a very interesting story. This relationship itself is valuable, but the creation of the relationship is usually pretty obvious from context.
In the specific case of PHI1134, various scripts are racing one another, but I don't think this story is of much value in the general case anyway.
Test Plan: Edited parent/child revisions, no more feed stories.

Summary:
Depends on D20419. Ref T13277. Fixes T8936. Fixes T9383. Fixes T12300. When you push arbitrary refs to Phabricator, the push log currently complains if those refs are not tags or branches.
Upstream Git now features "notes", and there's no reason to prevent writes to arbitrary refs, particularly beause we plan to start using them soon (see T13278).
Allow these writes as affecting raw refs.
Test Plan:
- Pushed an arbitrary ref.
- Pushed some Git notes.
- Wrote a Herald ref rule, saw "ref" in the dropdown.

Summary:
Depends on D20416. Ref T13269. See D20329.
If you try to save an "Assign to" rule with no assignee, we currently replace the control with an "InvalidRule" control that isn't editable. We'd prefer to give you an empty field back and let you pick a different value.
Differentiate between "bad record format" (i.e., we can't really do anything with this) and "bad record value" (i.e., everything is structurally fine, you just typed the wrong thing). In the latter case, we still build a properly typed rule for the UI, we just refuse to update storage until you fix the problem.
Test Plan:
First, hit the original issue and got a nicer UI with a more consistent control width (note full-width error):
{F6374205}
Then, applied the rest of the patch and got a normal "fix the issue" form state instead of a dead-end:
