c458b50b85 Render charts from storage instead of just one ad-hoc hard-coded chart
Summary:
Ref T13279. This changes the chart controller:

  - if we have no arguments, build a demo chart and redirect to it;
  - otherwise, load the specified chart from storage and render it.

This mostly prepares for "Chart" panels on dashboards.

Test Plan: Visited `/fact/chart/`, got redirected to a chart from storage.

06778ea550 Separate the "configuration" and "evaluation" phases of chart functions
Summary:
Depends on D20446. Currently, chart functions are both configured through arguments and evaluated through arguments. This sort of conflates things and makes some logic more difficult than it should be.

Instead:

  - Function arguments are used to configure function behavior. For example, `scale(2)` configures a function which does `f(x) => 2 * x`.
  - Evaluation is now separate, after configuration.

We can get rid of "sourceFunction" (which was basically marking one argument as "this is the thing that gets piped in" in a weird magical way) and "canEvaluate()" and "impulse".

Sequences of functions are achieved with `compose(u, v, w)`, which configures a function `f(x) => w(v(u(x)))` (note order is left-to right, like piping `x | u | v | w` to produce `y`).

The new flow is:

  - Every chartable function is `compose(...)` at top level, and composes one or more functions. `compose(x)` is longhand for `id(x)`. This just gives us a root/anchor node.
  - Figure out a domain, through various means.
  - Ask the function for a list of good input X values in that domain. This lets function chains which include a "fact" with distinct datapoints tell us that we should evaluate those datapoints.
  - Pipe those X values through the function.
  - We get Y values out.
  - Draw those points.

Also:

  - Adds `accumluate()`.
  - Adds `sum()`, which is now easy to implement.
  - Adds `compose()`.
  - All functions can now always evaluate everywhere, they just return `null` if they are not defined at a given X.
  - Adds repeatable arguments for `compose(f, g, ...)` and `sum(f, g, ...)`.

70c643c685 Simplify implementation of "pure" Chart functions
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?

d8dba26a08 Add a "sin()" function to charts
Summary:
Depends on D20443. Ref T13279. This is probably not terribly useful on its own, but is mostly a function which takes another function as an argument, and a step toward more useful functions like arithmetic and drawing a picture of an owl.

The only structural change here is that functions now read data parameters (domain, sample limit) using a more tailored "ChartDataQuery" instead of reading the actual axis. Mostly, I want a more cohesive representation of query state that can be easily passed to sub-functions, as here.

23d8f000f7 Select the domain (X-axis range) for charts before pulling data
Summary:
Depends on D20441. Ref T13279. Currently, we pull all the data, then decide what the X-axis should look like.

Since users will reasonably want to do stuff like "show me march-april 2018" in the future, we need to move toward flipping this around so that we can support cases where the domain is specified by the user.

For actual chart functions (like "constant(3)" or "cos(x)"), we must also know the domain before we pull data, since there are an infinite number of places where we can evaluate the function "constant(3)".

See note in T13279 about continunity.

954831f533 Separate chart functions into a class tree
Summary:
Depends on D20440. Ref T13279. Create a class to represent a chartable function: something we can get some data points out of.

Then, make the chart chart two functions.

For now, the only supported function is "fact(key)", which pulls data from the Facts ETL pipeline, identified by "key", and takes no other arguments.

In future changes, I plan to support things like "fact(tasks.open.project, PHID-PROJ-xyz)", "constant(1000)" (e.g. to draw a goal line), "sum(fact(...), fact(...))" (to combine data from several projects), and so on.

The UI may not expose this level of power for a while (or maybe ever) but until we get close enough to the UI that these features are a ton of extra work I'm going to try to keep things fairly flexible/modular.

45b3c23148 Fetch chart data via async request and redraw charts when the window is resized
Summary:
Depends on D20439. Ref T13279. Some day, charts will probably need to reload themselves or do a bunch of defer/request-shaping magic when they're on a dashboard with 900 other charts.

Give the controller separate "HTML placeholder" and "actual data" modes, and make the placeholder fetch the data in a separate request.

Then, make the chart redraw if you resize the window instead of staying at whatever size it started as.

Test Plan:
  - Loaded a chart, saw it load data asynchronously.
  - Resized the window, saw the chart resize.

02981f0add Fix negative chart values, add storage for charts
Summary:
Ref T13279. I think I'm going to fling some stuff at the wall for a bit here and hope most of it sticks, so this series of changes may not be terribly cohesive or focused. Here:

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.

Test Plan: Viewed a fact series with negative values. Ran `bin/storage upgrade`.

Depends on D19120. Ref T13083. When you write a fact engine, it's currently somewhat difficult to figure out exactly what it's doing. It would also be difficult to diagnose bugs or report them to the upstream.

0dee34b3fa Make Facts more modern, DRY, and dimensional
Summary:
Ref T13083. Facts has a fair amount of weird hardcoding and duplication of responsibilities. Reduce this somewhat: no more hard-coded fact aggregates, no more database-driven list of available facts, etc. Generally, derive all objective truth from FactEngines. This is more similar to how most other modern applications work.

For clarity, hopefully: rename "FactSpec" to "Fact". Rename "RawFact" to "Datapoint".

Split the fairly optimistic "RawFact" table into an "IntDatapoint" table with less stuff in it, then dimension tables for the object PHIDs and key names. This is primarily aimed at reducing the row size of each datapoint. At the time I originally wrote this code we hadn't experimented much with storing similar data in multiple tables, but this is now more common and has worked well elsewhere (CustomFields, Edges, Ferret) so I don't anticipate this causing issues. If we need more complex or multidimension/multivalue tables later we can accommodate them. The queries a single table supports (like "all facts of all kinds in some time window") don't make any sense as far as I can tell and could likely be UNION ALL'd anyway.

Remove all the aggregation stuff for now, it's not really clear to me what this should look like.

Test Plan: Ran `bin/fact analyze` and viewed web UI. Nothing exploded too violently.

a4784e03ff [Redesign] Add Table, Collapse support to ObjectBox
Summary: Converts most all tables to be directly set via `setTable` to an ObjectBox. I think this path is more flexible design wise, as we can change the box based on children, and not just CSS. We also already do this with PropertyList, Forms, ObjectList, and Header. `setCollapsed` is added to ObjectBox to all children objects to bleed to the edges (like diffs).

Test Plan: I did a grep of `appendChild($table)` as well as searches for `PHUIObjectBoxView`, also with manual opening of hundreds of files. I'm sure I missed 5-8 places. If you just appendChild($table) nothing breaks, it just looks a little funny.

- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.

486f7c1e8e Add aggregated facts to the Facts application
Summary:
Some facts are aggregations of other facts. For example, we may compute how many times each macro is used in each object as a "raw fact":

  Dnnn uses macro "psyduck" 6 times.

But we want to present this data in aggregate form, e.g. "order macros by popularity". We can do this at runtime and it probably won't be too awful a query, but we can also aggregate it cheaply:

  Macro "psyduck" is used 3920 times across all objects.

...and then do a query like "select macros ordered by usage".

"Aggregate" facts support facts like this. The aggregate facts I've implemented are:

  - Count of all objects.
  - Count of objects of type X.
  - Last time facts were updated.

These clearly fit the "aggregate" facts template well. I'm not 100% sure macros do. We can use this table to answer a question like "What are the most popular macros, ordered by use?" We can also use it to answer a question like "What are the most popular macros in the last 6 months?", if we build a specific fact for that. But we can't use it to answer a question like "What are the most popular macros between times X and Y?". Maybe that's important; maybe not.

This seems like a good fit for at least some types of facts.

I'll de-magic the keys a bit in the next diff.

Test Plan: Ran the engines and got some aggregated facts about other facts.
