Make tests use SOURCECRED_GITHUB_TOKEN (#1124)
Across SourceCred usage, we depend on the `SOURCECRED_GITHUB_TOKEN`
environment variable being set. Confusingly, some tests expect
`GITHUB_TOKEN` instead of `SOURCECRED_GITHUB_TOKEN`.

This commit resolves that inconsistency, by having all tests that read
from the environment use `SOURCECRED_GITHUB_TOKEN`. This was already
available as a secret in our CI configuration, so no change is needed
there. (After this merges, we may remove the GITHUB_TOKEN variable from
the environment.)

Test plan: `yarn test --full` passes without the environment variable
set. Also, the following grep produces only innocuous hits.

```
git grep -P "(?<\!SOURCECRED_)GITHUB_TOKEN"
```

refactor: `load` uses dependency injection (#1123)
This commit refactors the `sourcecred load` CLI command so that it uses
dependency injection, much like the testing setup #1110. This makes it
feasible to test "surface logic" of how the CLI parses flags and
transforms them into data separately from the "piping logic" of invoking
the right API calls using that data.

This is motivated by the fact that I have other pulls on the way that
modify the `load` command (e.g. #1115) and testing them within the
current framework is onerous.

Test plan:
This is a pure refactoring commit, which substantially re-writes the
unit tests. The new unit tests pass (`yarn test --full` is happy).

Note that `yarn test -full` also includes a sharness test that does an
E2E usage of `sourcecred load`
(see sharness/test_load_example_github.t), so we may be confident that
the command still works as intended.

Add `sourcecred pagerank` for backend pagerank (#1114)
This commit adds a new CLI command, `pagerank`, which runs PageRank on a
given repository. At present, the command only ever uses the default
weights, although I plan to make this configurable in the future. The
command then saves the resultant pagerank graph in the SourceCred
directory.

On its own, this command is not yet very compelling, as it doesn't
present any easily-consumed information (e.g. users' scores). However,
it is the first step for building other commands which do just that. My
intention is to make running this command the last step of `sourcecred
load`, so that future commands may assume the existence of pagerank
scores for any loaded repository.

Test plan: The new command is thoroughly tested; see
`cli/pagerank.test.js`. It also has nearly perfect code coverage (one
line missing, the dependency-injected real function for loading graphs).

Additionally, the following sequence of commands works:
```
$ yarn backend
$ node bin/sourcecred.js load sourcecred/pm
$ node bin/sourcecred.js pagerank sourcecred/pm
$ cat $SOURCECRED_DIRECTORY/data/sourcecred/pm/pagerankGraph.json
```

Material progress on #967.

Add `fetchGithubOrg` for loading organizations (#1117)
This commit adds a module, `fetchGithubOrg`, which loads data on GitHub
organizations, most notably including the list of repositories in that
org.

The structure of this commit is heavily influenced by review feedback
from @wchargin's [review] of a related PR.

Test plan: This logic depends on actually hitting GitHub's API, so the
tests are modeled off the related `fetchGithubRepo` module. There is a
new shell test, `src/plugins/github/fetchGithubOrgTest.sh`, which
verifies that that the org loading logic works via a snapshot.

To verify the correctness of this commit, I've performed the following
checks:

- `yarn test --full` passes
- inspection of `src/plugins/github/example/example-organization.json`
confirms that the list of repositories matches the repos for the
"sourcecred-test-organization" organization
- manually breaking the snapshot (by removing a repo from the snapshot)
causes `yarn test --full` to fail
- running `src/plugins/github/fetchGithubOrgTest.sh -u` restores the
snapshot, afterwhich `yarn test --full` passes again.

Refactor loadGraph out of exportGraph (#1113)
This pulls the logic for loading a SourceCred graph from disk out
`cli/exportGraph` and into `analysis/loadGraph`. The rationale is that
`exportGraph` is not the only command that wants the ability to load a
graph from the analysis adapters.

The new command has a clean return signature that reports whether the
load was successful, or failed because the graph wasn't loaded, or
failed due to an error in plugin code.

Testing of the loading logic has been moved to `loadGraph.test`, and the
CLI has been refactored so that the loadGraph method is dependency
injected. This allows for (IMO) cleaner testing of the CLI method.

There is one (deliberate) change in behavior, which is that the command no
longer throws an error if no plugins are included; instead it will just
export an empty graph. I don't have a strong preference between the two
behaviors; changing it was just more convenient.

Test plan: New unit tests have been added, and tests of the cli command
have been re-written. As a sanity check, I've verified that the
following sequence still works:

```
$ yarn backend
$ node bin/sourcecred.js load sourcecred/pm
$ node bin/sourcecred.js export-graph sourcecred/pm
```

Nearly perfect code coverage is maintained. One line is uncovered, and
it's the line that injects in the actual graph loading behavior.

PagerankGraph: add neighbors + score decomposition (#1094)
This commit adds a `neighbors` method to `PagerankGraph`. This is an
augmented version of `Graph.neighbors`. It returns the base data from
`Graph.neighbors` as well as the score, the edge weights, and the score
contribution. The score contribution basically means how much score was
contributed from the target node by this particular neighbor connection.

When the graph is well-converged, a node's score will be the sum of all
its neighbors' score contributions, as well as the contribution it
received from its synthetic loop edge. So, for completeness sake, I
added another method, `syntheticLoopScoreContribution`, which computes
how much score a node received from its synthetic loop edge. (This value
should usually be close to 0).

You can think of these two methods as providing a replacement for the
`PagerankNodeDecomposition` logic.

Test plan: I've added tests that verify:
- That neighbors returns results consistent with Graph.neighbors
- That neighbors' score contributions are computed correctly
- That neighbors errors if the graph has been modified
- That synthetic score contributions are computed correctly
- That a node's score is the sum of all its contributions

Test plan: Unit tests included. Run `yarn test`.

Move default pagerank settings to pagerankGraph (#1112)
This commit moves the default Pagerank options out of
`analysis/pagerank` and to `core/pagerankGraph`. This reflects the
gradual migration of core pagerank logic into `pagerankGraph`.

Test plan: `yarn test` should suffice. It's a trivial change.

$ node bin/sourcecred.js load sourcecred/mission
$ node bin/sourcecred.js export-graph sourcecred/mission >
  /tmp/mission_graph.json

refactor repoIdRegistry (#1109)
This commit makes several improvements to `repoIdRegistry`:

- Create `writeRegistry` and `getRegistry` methods to abstract over
  needing to find the right file, populate an empty registry if its not
  available, etc.
- Create `getEntry` for efficiently checking whether a RepoId is in the
  registry
- Rename `addRepoId` to `addEntry` for consistency
- Add docstrings

The `load` command has been refactored to use the new methods.

Test plan: Unit tests added, and they pass. The `load` command is
already thoroughly tested, so regressions are very unlikely.

pagerankGraph: add edge filter (#1105)
Part of ongoing work for #1020.

Test plan:
Added tests that mirror the edge filtering tests in `graph.test`
to check that `graph` and `pagerankGraph` return the same edges
with the given `EdgesOptions` parameter. Also added a sanity check
that a `weight` prop is returned from the iterator along with the edge.

Given the dependence on a helper function to test the edge
iterator's equality between graphs, I would suggest reviewers give
particular attention to that function:
`expectConsistentEdges()`

PagerankGraph: Add `totalOutWeight` (#1092)
This commit adds a `totalOutWeight` method to `PagerankGraph`.
For any given node, `totalOutWeight` reports the total weight traveling
away from the node on edges (including the synthetic loop edge). Using
totalOutWeight makes it possible to normalize the weights to get the
actual markov transition probabilities.

Test plan: Unit tests verify the following properties:
- An error is thrown if the requested node does not exist.
- An error is thrown if the graph has been modified.
- The out weights are computed correctly in the standard case.
- The out weights are computed correctly in the case where there are no
weights (except the synthetic loop weight)
- The out weights are still computed correctly after
JSON-deserialization.

Refactor pagerankGraph's node filter to throw error at call site (#1106)
Inspired by a [suggestion] @decentralion made to improve #1105
This will enable `pagerankGraph` to throw an error when it is
called with invalid option parameters. Previously, to elicit
this error we had to access the iterator through `Array.from()`
or similar.

Test plan:
Yarn test passes.
Specifically, I removed the `Array.from()` wrapper around `pagerankGraph`
in the test that checks to see that `pagerankGraph` throws an error when
`nodes()` is passed invalid options.

PagerankTable: Replace topLevelFilter with NodeType in props (#1103)
The motivation for this change is to make it easier
to access the selected Node's `name` prop for #576,
in which we plan to show a Card displaying summary
stats for the selected node. With only the `topLevelFilter`
available, it's trickier than it needs to be to find out
a node type's `name`.

Test Plan:
* Yarn test passes.
* Visual/Manual inspection of table doesn't surface any issues.
* Updated `it("filter defaults to defaultNodeFilter if available")`
to `it("selectedNodeType defaults to defaultNodeType if available")`.
* Verified that the above new test is failable in several ways by
mangling the tests to test for the wrong node type and mangling the
code to set the wrong node type.
* Since we factored out 'topLevelFilter' and 'defaultNodeFilter',
running `git grep -i topLevelFilter` and `git grep -i defaultNodeFilter`
turns up empty, just to make sure those terms aren't hanging
around to confuse anybody in the future.
* I don't think changing the `prop` parameter warrants any
additional tests, as the current tests verify that the prop
is passed in correctly.

This was at @decentralion's suggestion, following the Contributing
Guideline's Kent Beck quote of making the easy change to make the
change we were originally after (#576) easier. 🙌

Highlight tableRows on :hover and :focus-within (#1059)
* Highlight tableRows on :hover and :focus-within
Resolves #1041

The purpose of this commit is to make the pagerankTable easier
to read, as it's currently difficult to distinguish which score is
associated with which row because of the tight spacing of the
rows and the space between the score column and the row detail column.

@wchargin provided the implementation using `linearGradient()`
and `backgroundImage`s.

A side effect of highlighting the row on `focus-within` is that the rows
will become highlighted when the expand button is clicked, which we
decided was acceptable.

Test plan:

Yarn test passes.

To test the new highlight behavior, visual/manual inspection
passes.

Also added the Aphrodite className to the snapshot
tests. The combination of testing the className + inline style props
should make these tests sensitive to UI changes in the future.

Add optional node prefix filter to pagerankGraph (#1090)
Continuing work on #1020.
Adding an optional parameter to `nodes()` which enables optional
node prefix filtering.

Test plan:

@decentralion suggested on Discord that the tests should verify:
1) the parameter was passed to `_graph` correctly
2) the augmentation logic was applied correctly

The tests I added are identical to the tests in `graph.test`, except
that they verify that the result of `pagerankGraph` matches that of
`graph`. On one hand, this creates a dependence on `graph`,
as these tests don't verify that the filter works correctly, only that
graph has applied the filter and returned the iterator.
However, my prevailing thought is that it isn't `pagerankGraph's` responsibility
to test the behavior of `graph`, and so testing the exact filter results
of `pagerankGraph` like we do in `graph.test` isn't the best strategy, and
testing that `pagerankGraph`'s results equal `graph`'s results is a better strategy.

The tests also check that a `score` is provided alongside each `node` in the iterator,
to minimally satisfy @decentralion's second spec.

yarn test passes.

PagerankGraph: Add toJSON/fromJSON (#1088)
* PagerankGraph: Add toJSON/fromJSON

This commit adds serialization logic to `PagerankGraph`. As with many
things in PagerankGraph, it's based on the corresponding logic in `Graph`.
Much like graph, it stores data associated with nodes and edges (in this
case, the scores and edge weights) in an ordered array rather than a
map, so as to avoid repetitiously serializing the node and edge
addresses.

Test plan: Unit tests added, and they should be sufficient. Also take a

Retrieve sorted nodes/edges from GraphJSON (#1015)
As discussed in #1004, we want to be able to package metadata with a
graph's nodes and edges. We can do this much more compactly if we store
the metadata as an array, ordered by the corresponding node/edge
address, rather than storing a map. The disadvantage is that clients
then need to manually sort the graph addresses to deserialize.

This commit adds public methods that allow a client to efficiently
retrieve the sorted addresses from the GraphJSON (where they are already
serialized). This behavior is tested. Note that we appropriately don't
allow clients to peek and directly depend on the exact representation of
GraphJSON, we just promise that sorted address retrieval is possible.

Test plan: Unit tests added (and I verified that breaking the sorting
will fail the test).

Report Markov Chain convergence statistics (#1053)
This commit modifies `markovChain.findStationaryDistribution` so that
in addition to returning the final distribution, it also reports the 
final convergence delta.

This is motivated by the proposed API for the new PagerankGraph (see
[#1020]). Also, I think it makes a nice addition to the test code.

Note that this slightly changes the output from `findStationaryDistribution`,
because we now return the first distribution that is sufficiently converged,
rather than that distribution with one additional Markov action.

Enable loading private git repositories (#1085)
* Enable loading private git repositories

This commit enables loading private repositories, assuming that the user
has ssh-agent configured with keys to allow cloning the private
repository, and has provided a GitHub API token with permissions for the
repository in question.

I have not added automated testing. I don't think a cost-benefit
analysis favors adding such tests at this time:
- This code changes very infrequently, and so is unlikely to break
- If it does break, it will be pretty easy to catch and to fix
- the @sourcecred org is on a free plan, which doesn't allow private
repos, so setting up the test case is a bit of a pain

Test plan: `yarn test --full` passes, so I haven't broken existing Git
clone behavior. Locally, I am able to load private repositories.

Ian Darrow 642a62437b Update WeightSlider.js to allow 0 weights (#1005)
This commit #811, allowing users to set the weights of node/edge types to 0.

The WeightSlider now sets the weight to 0 when its dragged to its minimum value.
The logic for converting between weights and sliders has also been made more robust,
and is more thoroughly tested.

In cases where we wanted to set the weight to 0 (e.g. backwards Reaction edges),
the default weight has been changed.

Test plan:
Loading the UI, check that the sliders still work as expected (dragging them changes the displayed weight, dragging to the far left sets weight to 0). Check that the weights are consumed as expected (setting weight for issues to 0 leads to no cred for issues). Check that the weights for backwards reaction edges now have 0 weight. `git grep "TODO(#811)"` returns no hits.

Used @wpank's solution to add the Node link

`yarn test --full` is passing.

Additionally, the commands:
```sh
    filepath="./sharness/__snapshots__/example-github-load/data/sourcecred/example-github/github/view.json.gz" &&
    [ -f "${filepath}" ] &&  # sanity check
    diff -u \
        <(git show "HEAD:${filepath}" | gzip -d | jq .) \
        <(gzip -dc "${filepath}" | jq .) \
        ;
```

yields the following output:

Changelog: add rocket and eyes reaction types (#1075)

Update reaction types (#1068)
Resolves #1054
Added "ROCKET" and "EYES" to the list of reaction types.
Added "ROCKET" as a valid cred signal, kept "EYES" invisible.

My approach was to use `git git grep THUMBS_UP '*.js'`
 and `git grep ThumbsUp '*.js'` to find all the relevant files,
as suggested in #1054

**Test Plan**

1) Inspecting Sourcecred/Mission's UI:
[#13] contains: GOT 🚀 FROM 1 user
@BrianLitwin contains: REACTED 🚀 TO 1 issue
@BrianLitwin contains: REACTED 🚀 TO #13

2) Yarn Test passes

3) `github/edges.test` includes a snapshot test to verify
that we can create an edge using ROCKET

4) @wchargin also noted that:

```sh
diff -u <(git grep -c 'THUMBS_UP' '*.js') <(git grep -c 'ROCKET' '*.js')
diff -u <(git grep -c 'ThumbsUp' '*.js') <(git grep -c 'Rocket' '*.js')
```

passes.

`graphql/mirror.test` now includes "ROCKET" and "EYES" in the  example
GithubSchema, but their inclusion has no effect
on any tests.

Ana Noemi e0762303d4 Add descriptions for NodeTypes (#1044)
* Add descriptions for NodeTypes

As highlighted by @decentralion in issue #807, we need descriptions for Node and
Edge types in the UI to explain to users what each Node and Edge type does. This
PR modifies the type definition for `NodeType` and adds a `+description: string`
field, then updates all NodeTypes throughout the codebase with descriptions.

Test plan:

Verify that all tests pass and the descriptions makes sense.

Expose the Graph's modification count (#1055)
This commit adds a new `modificationCount` method to `Graph`, which
exposes's that graph's modification count. This enables clients to write
cached data structures on top of Graph, knowing that they can
programatically detect when the cache has been invalidated.

Test plan: Unit tests have been addded; `yarn test` passes.

This commit is motivated by work on #1020.

Rename "AppAdapter" -> "ExplorerAdapter" (#1052)
There are two kinds of plugin adapters: adapters for doing cred
analysis, called "analysis adapters", and adapters for the cred
explorer, which are confusingly called "app adapters".

This commit decreases the confusion by renaming app adapters to explorer
adapters across the codebase. In a future commit, I will add
documentation to the adapter interfaces so that it is clearer to a
newcomer to the codebase why these interfaces exist.

Thanks to @BrianLitwin, who asked a question during [office hours]
that surfaced this issue.

[office hours]: https://github.com/sourcecred/mission/issues/12

Test plan: `yarn test` passes, suggests that this rename went off
without a hitch. Code review as a sanity check.

Also: grepping for `AppAdapter` returns 0 results:
```
$ git grep AppAdapter | wc -l
0
```

Note: After producing this commit, I can confirm that the word "adapter"
starts to look like utter gibberish after you type it often enough.

Add documentation for `NodeType` and `EdgeType` (#1043)
This commit adds some docstrings for the concepts of NodeType and
EdgeType. I also swapped the order so that `NodeType` comes first,
which is more consistent with usage across the codebase.

This commit makes no changes to the actual code; the only effects
are re-organization and documentation.

Test plan: `yarn test` && human inspection

README: Update new contributor label to "good first issue" (#1048)
In response to SourceCred/Mission#15, we switched the default new contributor label from "Contributions Welcome" to "good first issue". This updates the README to reflect that change.

Test Plan: make sure the link redirects to our Issues page filtered for "good first issue" labels.

homepage: remove misleading CSS import (#1045)
Summary:
We use Aphrodite, not CSS imports, for styling. We do have a small
`index.css` file that is included during server-side rendering, and is
only referenced from `src/homepage/server.js`. But our `index.js` file
also has a superfluous `import "./style.css"`, which might suggest that
we support CSS imports more generally. This patch removes that import.

Thanks to @brianlitwin on Discord for pointing out that this might be
confusing.

Test Plan:
Verified that, under both `yarn start` and `yarn build`, the appearance
is the same, and the document still includes a `<style>` element with
the contents of `index.css` (which is included by `server.js`).

Add documentation to the Graph module (#1025)
* Add documentation to the Graph module

This commit adds a module-level docstring that gives an overview of the
Graph class and its importance to SourceCred, as well as adding
docstrings to specific methods.

Test plan:
In addition to review by the SourceCred maintainers, this should be
reviewed by at least one person who is not familiar with the codebase,
so that we can verify that it's actually working as documentation. :)

* Incorporate @wchargin's many suggestions.

Test plan: Human review.

Tests use yarn not npm (#1038)
Currently, our underlying test script uses npm rather than yarn to
execute the tests. This is awkward, because we use yarn everywhere else
in lieu of npm. It turns out that some setups have node available
without npm, and in such environments our tests fail with a cryptic
ENOENT error.

This changes the tests to use yarn instead.

Test plan: `yarn test --full` passes.

Thanks to @wpank for help uncovering this issue.

Make `yarn test` more quiet (#1037)
This commit adds a new runOption for execDependencyGraph, namely
`printVerboseResults`. If this flag is true, then execDependencyGraph
will print a "Full Results" section along with the standard error and
standard out of every task, regardless of whether it failed or
succeeded. (Note, this is the existing behavior for all invocations
prior to this commit).

If the flag is not true, then execDependencyGraph will not print a full
results section, and stdout/stderr will be logged only for tasks that
fail.

This commit also modifies `yarn test` to use the new flag so that it
prints verbose tests only when the `--full` option is provided. This is
consistent with our sharness behavior: we print the full sharness logs
only when `--full` was provided.

This fixes #1035, and ensures that running `yarn test` has a high signal
to noise ratio (i.e. it only shows an enumeration of top level tasks).
This improves the developer ergonomics of SourceCred by not having a
super commonly used and core script spam the user with mostly irrelevant
information.

Test plan:

Run `yarn test` when all tests are passing, and observe that the output
has much less noise:

```
yarn run v1.12.3
$ node ./config/test.js
tmpdir for backend output: /tmp/sourcecred-test-6337SZ9smvWsWvqE

Starting tasks
  GO   ensure-flow-typing
  GO   check-stopships
  GO   check-pretty
  GO   lint
  GO   flow
  GO   unit
  GO   backend
 PASS  check-stopships
 PASS  ensure-flow-typing
 PASS  flow
 PASS  backend
  GO   sharness
 PASS  sharness
 PASS  check-pretty
 PASS  lint
 PASS  unit

Overview
Final result:  SUCCESS
Done in 11.66s.
```

Run `yarn test` when there is a real failure (e.g. a unit test failure)
and observe that full details on the failure, including the output from
stdout/stderr, is still provided.

Run `yarn test --full` and observe that full, verbose logs are provided.

Add helpful message when missing gnu-coreutils (#1034)
As described in #1033: Currently, developers in environments without gnu
coreutils (notably: macOS) get an extremely confusing error message when
they run `yarn test`. This commit ensures that such users instead get a
helpful message with a link to the fix.

Follows @wchargin's proposed approach for fixing #1033, so that Mac
developers get clear guidance on how to get their development
environment working properly.

Expected behavior is that `yarn test` passes when GNU coreutils are
present, and fails with the following message when they are not:

Fixes #1033

```
 FAIL  check-gnu-coreutils
Exit code: 1
Contents of stdout:
    /home/dandelion/git/sc/sourcecred
Contents of stderr:
    Error: Your environment does not provide GNU coreutils
    You're likely developing on macOS.
    Please see the following link for a fix:
    https://github.com/sourcecred/sourcecred/issues/698#issuecomment-417202213
```

Test plan:

Verify that on a machine with gnu coreutils present, the command passes
and does not print irrelevant output.

Verify that on a machine without gnu coreutils available, the command
fails, and prints exactly the error message expected, without any extra
output related to the test's implementation.
