remove dep on `mkdirp` (#1253)
There's no need for us to depend on `mkdirp`, because the `fs-extra`
module already has `fs.mkdirp` and `fs.mkdirpSync`. This commit removes
the dep from our `package.json`, and removes all explicit imports of it.

Test plan: `yarn test --full` passes. `git grep "import mkdirp"` has no
hits.

Dandelion Mané 6bd7fe1154 Replace `Object.freeze` with `deepFreeze`
Throughout the codebase, we freeze objects when we want to ensure that
their properties are never altered -- e.g. because they are a plugin
declaration, or are being re-used for various test cases.

We generally use `Object.freeze`. This has the disadvantage that it does
not work recursively, so a frozen object's mutable fields and properties
can still be mutated. (E.g. if `const obj = Object.freeze({foo: []})`,
then `obj.foo.push(1)` will succeed in mutating the 'frozen' object).

Sometimes we anticipate this and explicitly freeze the sub-fields (which
is tedious); sometimes we forget (which invites errors). This change
simply replaces all instances of Object.freeze with [deep-freeze], so we
don't need to worry about the issue at all anymore.

Test plan: `yarn test` passes (after updating snapshots);
`git grep Object.freeze` returns no hits.

Dandelion Mané 0889a0a5d1 Use url encoding and make _getProjectIds async
Test plan: `yarn test --full` still passes. Also, I've ensured that the
async `_getProjectIds` is still usable in our webpack configs (via
modifying and testing the dependent commits).

Dandelion Mané 9b105ee4ce Add `core/project` and `core/project_io`
This creates a new `Project` type which will replace `RepoId` as the
index type for saving and loading data.

The basic data type is added to `project.js`. Rather than having a
`RepoIdRegistry`, I intend to infer the registry at build time by
scanning for available projects saved in the sourcecred directory. I've
added the `project_io` module for this task. It has methods for setting
up a project subdirectory, and loading the `Project` info from that
subdirectory.

To ensure that projects ids can be encoded even if they have symbols
like `/` and `@`, we base64 encode them.

To ensure that project ids can be retrieved at build time, the
`getProjectIds` method is factored out into its own plain ECMAScript
module. For all non-build time needs, it is re-exported from
`project_io`.

Test plan: Unit tests added; run `yarn test`.

greenkeeper[bot] 8d8804c246 Update dependencies to enable Greenkeeper 🌴 (#1231)
* chore(package): update dependencies

* revert tmp upgrade

I'm having test failures when `tmp` is upgraded; they seem to repro only
when many tests are running at once. Since we have no issues with the
older version of tmp, let's just keep an old tmp and inform Greenkeeper
not to touch it.

Test plan: `yarn test`

Dandelion Mané 493d7332c6 tweak: jest loads .mjs last
This resolves an issue that caused jest tests to fail when depending on
a module that ships .mjs files (encountered via a transitive dep of
react-markdown).

See https://github.com/facebook/create-react-app/pull/4085 for context.

Test plan: I have a future commit which tests a file that depends on
react-markdown. The tests fail to run before this commit, and they run
without issue afterwards.

Dandelion Mané 5dc7f440ce Initial Timeline Explorer
This commit adds a TimelineExplorer for visualizing timeline cred data.
The centerpiece is the TimelineCredChart, a d3-based line chart showing
how the top users' cred evolved over time. It has features like tooltips,
reasonable ticks on the x axis, a legend, and filtering out line
segments that stay on the x axis.

An inspection test is included, which you can check out here:
http://localhost:8080/test/TimelineCredView/

Also, you can run it for any loaded repository at:
http://localhost:8080/timeline/$repoOwner/$repoName

This commit also includes new dependencies:
- recharts (for the charts)
- react-markdown (for rendering the Markdown descriptions)
- remove-markdown (so the legend will be clean text)
- d3-time-format for date axis generation
- d3-scale and d3-scale-chromatic for color scales

Test plan: The frontend code is mostly untested, in keeping with my
observation that the costs of testing the old explorer were really high,
and the tests brought little benefit. However, I have manually tested it
thoroughly. Also, there is an inspection test for the TimelineCredView
(see above).

Dandelion Mané a0b754bb43 upgrade to webpack 4
Now that babel is upgraded, upgrading webpack was pretty
straightforward.

- We take advantage of the new `mode` config option, and no longer need
to manually set up Uglify plugin
- Uglifyjs is back, I checked the prod build output: it's very ugly
- I updated the RemoveBuildDirectoryPlugin per instructions, and
verified it still works.
- I verified that of `yarn backend`, `yarn build`, and `yarn start` all
still work as expected.

Dandelion Mané f77ff3ecd0 Upgrade babel to 7
I moved `config/babel.js` to `.babelrc.js` because it seemed like babel
7 really wanted that. I also blew away our (complicated, copied from
create-react-app) config and replaced it with a much, much simpler one.

Test plan: `yarn test` passes, `yarn start` still serves a working
server, and `scripts/build_static_site.sh` still produces a working
site.

Possibly we lost some nice features re: React debugging; if so I'll add
them back as I miss them.

Switch to flow v0.100.0 to try to fix CI issues (#1203)
Since upgrading to flow 0.102.0, we've been having CI issues where flow
fails as "out of retries". In my testing, downgrading flow seems to
resolve this, although it's hard to be certain as the issue strikes
sporadically.

Test plan: This commit definitely works locally; hopefully it will
consistently pass in CI as well.

After merging #1201, we started seeing build failures ([1], [2]) on

greenkeeper[bot] 4758cea2f8 Update dependencies to enable Greenkeeper 🌴 (#1201)
This commit enables Greenkeeper, along with an initial upgrade push for our dependencies.

I've reverted a number of upgrades, and also added them to the
greenkeeper ignore list. They mostly relate to babel/webpack stuff,
which I'm reluctant to dive into now (there have been major upgrades for
both babel and webpack) but we should address eventually. There are also
a few oddballs like whatwg-fetch and history.

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

Dandelion Mané 7a493b596d Update eslint and eslint configuration
This commit updates eslint from v4 to v6. In doing so, I've moved off of
the create-react-app base eslint config. We were on an old version (v2)
and it doesn't make sense to update to v4, as in v4 create-react-app
uses typescript. Also, it didn't make sense to stay on
create-react-app's v2 config, because then it had unmet peer dependency
constraints on old versions of eslint.

Instead, I've moved us to use the default rules for eslint,
eslint-plugin-react, and eslint-plugin-flowtype.

I also made some changes to the codebase to satisfy the new lint rules
that came with this change.

Test plan: `yarn test` passes.

Dandelion Mané eadcca8999 Upgrade flow to to 0.102.0
This necessitated a number of type fixes:
- Upgraded the express flow-typed file to latest
- Added manual flow error suppression to where the express flow-typed
file is still using a deprecated utility type
- Removed type polymorphism support on map.merge (see context here[1]).
We weren't using the polymorphism anywhere so I figured it was simplest
to just remove it.
- Improve typing around jest mocks throughout the codebase.

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

Dandelion Mané 29c9229c28 Update better-sqlite3 to v5
When we took a dep on better-sqlite3 in #836, we used a fork, because
better-sqlite3 did not yet support private in-memory databases via the
`:memory:` filepath. As of better-sqlite3 v5, this has been added to
mainline, so we no longer need the fork.

The v4->v5 transition involves some breaking changes. The only ones that
affected us were two field renames, from `lastUpdateROWID` to
`lastUpdateRowid`, and `returnsData` to `reader`.

Test plan:
After updating the field accesses, `yarn test --full` passes. For added
safety, I also blew away cache, loaded a nontrivial repository, and
verified that the full cred workflow still works.

Add a FileUploader component, with inspection test (#1149)
* Add FileUploader with inspection test

TODO: get it working

* Add a FileUploader component, with inspection test

This adds a FileUploader component, which allows the user to upload JSON
files. Rather than using automated testing, it has an inspection test.
The inspection test may be run by navigating to:
http://localhost:8080/test/FileUploader/

This commit also adds some basic utility functions for defining
inspection tests to `routeData.js`. We should improve support for
inspection tests in the future; see [#1148].

Brian Litwin 0f038305a2 Add CLI command to clear sourcecred data directory (#1111)
Resolves #1067

Adds the CLI commands:
`sourcecred clear --all` -- removes the $SOURCECRED_DIRECTORY
`sourcecred clear --cache` -- removes the cache directory
`sourcecred clear --help` -- provides usage info
`sourcecred clear` -- prompts the user to be more specific

Test plan:
The unit tests ensure that the command is properly wired into the
 sourcecred CLI, including help text integration. However, just to be
safe, we can start by verifying that calling `sourcecred` without
arguments lists the `clear` command as a valid option, and that
calling `sourcecred help clear` prints help information. (Note: it's
necessary to run `yarn backend` before testing these changes)

The unit tests also ensure that the command removes the proper
directories, so there isn't really a need to manually test it,
although the reviewer may choose to do so to be safe.

Although out of scope for unit tests on this function, we can also do
integration tests, to make sure that running the clear command doesn't
leave the sourcecred directory in an invalid state from the perspective of the `load` command.

```js
$ yarn backend;
$ node bin/sourcecred.js load sourcecred/example-github;
$ node bin/sourcecred.js clear --cache;
$ node bin/sourcecred.js load sourcecred/example-github;
$ node bin/sourcecred.js clear --all;
$ node bin/sourcecred.js load sourcecred/example-github;
```
The expected behavior of the above command block is that the load command never fails or throws an error.

@decentralion and I discussed the scenario where `rimraf` errors.
We decided that testing this scenario wasn't necessary, because
`rimraf` doesn't error if a directory doesn't exist, and
rimraf's maintainer suggests [monkey-patching the fs module]
to get rimraf to error in testing scenarios.

Thanks @decentralion for reviewing and pair-programming this with me.

Port skeleton of Odyssey frontend (#1132)
This commit integrates an bare skeleton of the odyssey frontend that we
implemented in the [odyssey-hackathon] repository. You can see the
working frontend that we are trying to port over at
[sourcecred.io/odyssey-hackathon/][scio].

The prototype in the other repository has some tooling choices which are
incompatible/redundant with decisions in our codebase (sass vs
aphrodite), and requires some tools not yet present here
(svg-react-loader). This commit includes the build and integration work
needed to port the prototype frontend into mainline SourceCred. The
frontend scaffold isn't yet integrated with any "real" Odyssey data.

One potential issue: right now, every page that is rendered from the
SourceCred homepage is contained within a [homepage/Page], meaning that
it has full SourceCred website styling, along with the SourceCred
website header. The [application][scio] also has a header. Currently, I
work around this by having the Odyssey UI cover up the base header (via
absolute positioning), which works but is hacky. We can consider more
principled solutions:

- Finding a way to specify routes which aren't contained by
[homepage/Page]; maybe by adding a new top-level route
[here][route-alternative].
- Unify the headers for the Odyssey viewer and the page as a whole
(sounds like inappropriate entanglement?)
- Have a website header and also an application header (sounds ugly?)

[homepage/Page]: ee1d2fb996/src/homepage/Page.js
[route-alternative]: ee1d2fb996/src/homepage/createRoutes.js (L17)

Test plan: Run `yarn start`, and then navigate to
`localhost:8080/odyssey/`. observe that a working website is displayed,
and that the cred logo next to the word "SourceCred" is loaded properly
(i.e. svg-react-loader is integrated properly). Observe that there are
no build/compile errors from either `yarn start` or `yarn build`. Also,
observe that the UI looks passably nice, and that if the number of
elements in the entity lists is larger than can be displayed, the
sidebar pane scrolls independently.

The UI was tested in both Chrome and Firefox.

Thanks to @jmnemo, as the implementation is based on [his work].

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.

Summary:
Tests that run only on nightly builds (`yarn test --full`) and fail only
on CI (not locally) are a bit more inconvenient to debug when they fail.
This patch makes the `yarn test --full` script print all the

this for `yarn test` simply because it generates a ton of spam even on
successful tests.

deps: add `better-sqlite3` (#836)
Summary:
I selected this over the alternatives, `sqlite` and `sqlite3`, primarily
because its README explicitly acknowledges that using asynchronous APIs
for CPU-bound or serialized work units are worse than useless. To me,
this is a sign that the maintainer has his head on straight.

The many-fold performance increase over `sqlite` and `sqlite3` is nice
to have, too.

For now, we use my fork of the project, which includes a critical patch
to support private in-memory databases via SQLite’s standard `:memory:`
filepath. When this patch is merged upstream, we can move back to
mainline.

Test Plan:
The following session demonstrates the basic API and validates that the
install has completed successfully:

```js
const Database = require("better-sqlite3");
const db = new Database("/tmp/irrelevant", {memory: true});

db.prepare("CREATE TABLE pythagorean_triples (x, y, z)").run();
const insert = db.prepare("INSERT INTO pythagorean_triples VALUES (?, ?, ?)");
const get = db.prepare(
  "SELECT rowid, x * x + y * y AS xxyy, z * z AS zz FROM pythagorean_triples"
);

function print(x) {
  console.log(JSON.stringify(x));
}

print(insert.run(3, 4, 5));
print(get.all());
print(insert.run(5, 12, 13));
print(get.all());

db.prepare("DELETE FROM pythagorean_triples").run();
print(get.all());
```

It prints:

```js
{"changes":1,"lastInsertROWID":1}
[{"rowid":1,"xxyy":25,"zz":25}]
{"changes":1,"lastInsertROWID":2}
[{"rowid":1,"xxyy":25,"zz":25},{"rowid":2,"xxyy":169,"zz":169}]

taking advantage of the isomorphic `pako` library for gzip encoding and
decoding.

Sample space savings (note that post bodies are included; i.e., #747 has
not been applied):

Closes #750.

Test Plan:
Comparing the raw old version with the decompressed new version shows
that they are identical:

```
$ <~/tmp/sourcecred/data/sourcecred/example-github/github/view.json \
> shasum -a 256 -
63853b9d3f918274aafacf5198787e18185a61b9c95faf640a1e61f5d11fa19f  -
$ <~/tmp/sourcecred/data/sourcecred/example-github/github/view.json.gz \
> gzip -dc | shasum -a 256
63853b9d3f918274aafacf5198787e18185a61b9c95faf640a1e61f5d11fa19f  -
```

Additionally, `yarn test --full` passes, and `yarn start` still loads
data and runs PageRank properly.

Retry GitHub queries with exponential backoff (#699)
Summary:
This patch adds independent exponential backoff to each individual
GitHub GraphQL query. We remove the fixed `GITHUB_DELAY_MS` delay before
each query in favor of this solution, which requires no additional
configuration (thus resolving a TODO in the process).

We use the NPM module `retry` with its default settings: namely, a
maximum of 10 retries with factor-2 backoff starting at 1000ms.
Empirically, it seems very unlikely that we should require much more
than 2 retries for a query. (See Test Plan for more details.)

This is both a short-term unblocker and a good kind of thing to have in
the long term.

Test Plan:
Note that `yarn test --full` passes, including `fetchGithubRepoTest.sh`.
Consider manual testing as follows.

Add `console.info` statements in `retryGithubFetch`, then load a large
repository like TensorFlow, and observe the output:

```shell
$ node bin/sourcecred.js load --plugin github tensorflow/tensorflow 2>&1 | ts -s '%.s'
0.252566 Fetching repo...
0.258422 Trying...
5.203014 Trying...
[snip]
1244.521197 Trying...
1254.848044 Will retry (n=1)...
1260.893334 Trying...
1271.547368 Trying...
1282.094735 Will retry (n=1)...
1283.349192 Will retry (n=2)...
1289.188728 Trying...

1752.023697 Stringifying...
1754.697116 Writing...
1754.697772 Done.
```

This took just under half an hour, with 264 queries total, of which:
  - 225 queries required 0 retries;
  - 38 queries required exactly 1 retry;
  - 1 query required exactly 2 retries; and
  - 0 queries required 3 or more retries.

Add `createRelativeHistory` history implementation (#666)
Summary:
See #643 and the module docstring on `createRelativeHistory.js` for
context and explanation.

This patch adds `history@^3.0.0` as an explicit dependency—previously,
we were depending on it only implicitly through `react-router` (which
was fine then, but is not now). The dependency is chosen to match the
version specified in `react-router`’s `package.json`.

Test Plan:
Extensive unit tests included, with full coverage; `yarn test` suffices.

In addition to the obvious benefit of having a favicon, this gets rid of

Remove service workers entirely (#635)
Summary:
This is a follow-up to #514, wherein we disabled new service workers and
instructed any existing service workers to self-destruct. (See that PR
for the rationale.) This commit removes them from our codebase entirely,
enabling us to slim down our build process and our build output.

Test Plan:
Running `yarn start` still works. Building the static site and exploring
it works, too.

Add `sharness` for shell-based testing (#597)
Summary:
We will shortly want to perform testing of shell scripts; it makes the
most sense to do so via the shell. We could roll our own testing
framework, but it makes more sense to use an existing one. By choosing
Sharness, we’re in good company: `go-ipfs` and `go-multihash` use it as
well, and it’s derived from Git’s testing library. I like it a lot.

For now, we need a dummy test file; our test runner will fail if there
are no tests to run. As soon as we have a real test, we can remove this.

This commit was generated by following the “per-project installation”
instructions at https://github.com/chriscool/sharness, and by
additionally including that repository’s `COPYING` file as
`SHARNESS_LICENSE`, with a header prepended. I considered instead adding
Sharness as a submodule, which is supported and has clear advantages
(e.g., you can update the thing), but opted to avoid the complexity of
submodules for now.

Test Plan:
Create the following tests in the `sharness` directory:

```shell
$ cat sharness/good.t
#!/bin/sh
test_description='demo of passing tests'
. ./sharness.sh
test_expect_success "look at me go" true
test_expect_success EXPENSIVE "this may take a while" 'sleep 2'
test_done
# vim: ft=sh
$ cat sharness/bad.t
#!/bin/sh
test_description='demo of failing tests'
. ./sharness.sh
test_expect_success "I don't feel so good" false
test_done
# vim: ft=sh
```

Note that `yarn sharness` and `yarn test` fail appropriately. Note that
`yarn sharness-full` fails appropriately after taking two extra seconds,
and `yarn test --full` runs the latter. Each failure message should
print the name of the failing test case, not just the suite name, and
should indicate that the passing tests passed.

Then, remove `sharness/bad.t`, and note that the above commands all
pass, with the `--full` variants still taking longer.

Finally, remove `sharness/good.t`, and note that the above commands all
pass (and all pass quickly).

Refine the build directory cleaning logic (#577)
Summary:
We were asking the `clean-webpack-plugin` to remove the `build/`
directory in all cases. However, Webpack accepts a command-line
parameter `--output-path`. When such a parameter is passed, we would be
removing the wrong directory.

The proper behavior is to remove “whatever the actual output path is”.
Webpack exposes this information, but it appears that the
`clean-webpack-plugin` does not take advantage of it. Therefore, this
commit includes a small Webpack plugin to do the right thing.

Test Plan:
Test that the behavior is correct when no output directory is specified:
```
mkdir -p build && touch build/wat && yarn build && ! [ -e build/wat ]
```

Test that the behavior is correct with an explicit `--output-path`:
```
outdir="$(mktemp -d)" && touch "${outdir}/wat" && \
    yarn build --output-path "${outdir}" && \
    ! [ -e "${outdir}/wat" ]
```

Test that the plugin refuses to remove the root directory:

```
! yarn build --output-path . && \
    sed -i '/path: /d' config/makeWebpackConfig.js && ! yarn build
```

(Feel free to comment out the actual `rimraf.sync` line in the plugin
when testing this.)

package.json: reorganize test commands (#571)
Summary:
Running `yarn test` (equiv. `npm test` or `npm run test`) now runs all
checks. It takes the place of the former `yarn travis`. This is more in
line with the expectation of a top-level `test` command: if it passes,
your code is good.

The `unit` command now runs Jest once, not in watch mode. It takes the
place of the former `ci-test`. To run tests in watch mode, run any of
the following:

  - `yarn unit --watch`, or
  - `npm run unit -- --watch`, or
  - `npm unit -- --watch`.

This behavior is more consistent with the standard behavior of commands
like `make test`. It is also empirically what @wchargin and
@decentralion want most of the time.

Test Plan:
Verify that each of the scripts `test`, `unit`, and `coverage` passes.
Verify that each of the aforementioned `--watch` invocations works.
Verify that `.travis.yml` has the correct `script:` command.

new-webpack: clean `build/` before prod (#568)
Summary:
In our current system, we build by invoking `scripts/build.js`, which
begins by removing the `build/` directory. This behavior is nice,
because it prevents cross-contamination between builds. In this commit,
we add a plugin to achieve the same result from directly within Webpack.

Test Plan:
Run

```
mkdir -p ./build
touch ./build/wat
NODE_ENV=production node ./node_modules/.bin/webpack \
    --config config/makeWebpackConfig.js
```

and ensure that `./build/wat` does not exist after the build completes.

Upgrade Flow to v0.72.0 (#285)
Summary:
A few changes were made to code that is correct (as far as I can tell),
but for which Flow can no longer infer a type parameter. The change is a
bit more annoying than it otherwise would be, because this particular
file is run directly via node and so must use Flow’s comment syntax for
type annotations, but Prettier breaks such comments in the cases that we
need. We work around this by rewriting the original code to avoid the
need for comments.

Test Plan:
In addition to standard CI, run `yarn build` and then run a server from
`build/`, to see that the production build produces a working bundle.
(That the app loads and renders is sufficient.)

Target latest Node for backend applications (#213)
Summary:
Consequently, Babel won’t transform classes to their roughly equivalent
ES5 counterparts, etc.

Test Plan:
Create `src/classy.js` with `class X {}; console.log(X);`. Then, add a
build target for `classy: resolveApp("src/classy.js"),` in `paths.js`.
Use `yarn backend` and inspect the contents of `bin/classy.js`; in
particular, look at the definition of `X` (whatever the argument to
`console.log` is). Before this commit, the result will be a big
complicated mess. After this commit, it will be `class X {}`.

Note also that `yarn travis --full` passes, indicating that the two
manual tests, which call out to the utilities in `bin/`, still work.

Implement a custom CI script (#189)
Summary:
This CI script accomplishes two tasks:
 1. It speeds up our build by parallelizing where possible.
 2. It opens the possibility for running Travis cron jobs.

Currently, this script by default does the same amount of work as our
current CI script. However, I’d like to move `yarn backend` into the
list of basic actions: a backend build failure should fail CI.

Note: this script is written to be executable directly by Node, so we
can’t use Flow types with the standard syntax. Instead, we use the
comment syntax: https://flow.org/en/docs/types/comments/

Test Plan:
The following should pass with useful output:
  - `npm run travis`
  - `GITHUB_TOKEN="your_github_token" npm run travis -- --full`

The following should fail with useful output:
  - `npm run travis -- --full` (fail)

To test different failure modes, it can be helpful to add
```js
    {id: "doomed", cmd: ["false"], deps: []},
    {id: "orphan", cmd: ["whoami"], deps: ["who", "are", "you"]},
```
to the list of `basicTasks` in `travis.js`.

To test performance:
```shell
$ time node ./config/travis.js >/dev/null 2>/dev/null

real    0m8.306s
user    0m20.336s
sys     0m1.364s

$ time bash -c \
>     'npm run check-pretty && npm run lint && npm run flow && CI=1 npm run test' \
>     >/dev/null 2>/dev/null

user    0m13.752s

Convert in-memory Git repos to cred graphs (#169)
Test Plan:
This snapshot test is too unwieldy to actually read—it’s 1000 lines of
opaque SHAs and thrice-stringified JSON objects—so it should be
interpreted as a regression test only. The programmatic tests should
suffice.

Remove `address.sortedByAddress` (#161)
Previously, the address module exported `sortedByAddress`, a utility
function that sorts an array of `Addressable`s. This function was only
used in test code.

This commit replaces it with generic usage of `lodash.sortBy`. This
reduces the API surface area of the module, and removes test-only code
from the exported api.

New dependency added: `lodash.sortby`

Load Git repositories into memory (#139)
Summary:
In this newly added module, we load the structural state of a git
repository into memory. We do not load into memory the contents of any
blobs, so this is not enough information to perform any analysis
requiring file diffing. However, it is sufficient to develop a notion of
“this file was changed in this commit”, by simply diffing the trees.

Test Plan:
Unit tests added; `yarn test` suffices. Reading these snapshots is
pretty easy, even though they’re filled with hashes:
  - First, read over the commit specifications on lines 69–83 of
    `loadRepository.test.js`, so you know what to expect.
  - In the snapshot file, keep handy the time-ordered list of commit
    SHAs at the bottom of the file, so that you know which commit SHA is
    which.
  - To verify that the large snapshot is correct: for each commit, read
    the corresponding tree object and make sure that the structure is
    correct.
  - To verify the small snapshot, just check that it’s the correct
    subset of the large snapshot.
  - If you want to verify that the SHA for a blob is correct, open a
    terminal and run `git hash-object -t blob --stdin`; then, enter the
    content of the blob and press `<C-d>`. The result is the blob SHA.

To run a sanity-check on a large repository: apply the following patch:

Standardize on Enzyme shallow rendering (#104)
Summary:
This commit moves our existing frontend tests to use Enzyme’s shallow
rendering API <http://airbnb.io/enzyme/docs/api/shallow.html>. The
benefit over also using `react-test-renderer` is simply consistency (the
two are functionally equivalent); the benefits over `mount` are that
subcomponents cannot contaminate the test state (i.e., you’re only
testing one component at a time), that the resulting snapshots are more
readable because the root props are not shown, and that the
implementation is more efficient. This is a follow-up to #102.

In a case where we actually need a full DOM tree, we should still feel
free to use `mount`, but we haven’t needed that yet.

Test Plan:
Verify that the new `ContributionList.test.js.snap` represents the same
data as the old one.

Use Enzyme to test ContributionList dynamics (#102)
Summary:
This is our first dynamic test of a React component! Enzyme looks pretty
easy to use to me, for both snapshot tests and interaction simulation.

In doing so, we catch a minor bug in the edge case where a contribution
is not owned by any plugin (`colSpan`, not `colspan`). This edge case
does not appear in the sample data, but it does appear in the test data,
even prior to this commit. The previous renderer, `react-test-renderer`,
appears not to surface this error. Furthermore, this bug did not cause
any user-visible errors except a `console.error`.

Test Plan:
Inspect the snapshot file to make sure that it is reasonable. (The
existing test case has its snapshot regenerated due to formatting
differences between the two renderers.)

To test that the browser error is fixed, render a contribution list on a
GitHub graph but with an empty adapter set. One way to do this is to comment out line 7 of
`standardAdapterSet.js`; alternately, you can use the React Dev Tools to
select the `ContributionList` node, then run
```js
$r.props.adapters.adapters = {};
$r.forceUpdate();
```
Note subsequently that there is no console error and that the `<td>`s in
question span three columns.

Begin work on contributions and adapters (#93)
Summary:
This commit begins to extend the artifact editor to display
contributions. To display contributions from arbitrary plugins, we need
to communicate with those plugins somehow. We do so via an adapter
interface that plugins implement; included in this commit is an
implementation of this interface for the GitHub plugin (partially: we
punt on rendering).

This includes a snapshot test. The snapshot format is designed to be
human-readable and -auditable so that it can serve as documentation.

Test Plan:
Run the application with `yarn start`. Then, fetch a graph and watch as
its contributions appear in the view.

Configure Webpack for backend applications (#84)
Summary:
Running `yarn backend` will now bundle backend applications. They’ll be
placed into the new `bin/` directory. This enables us to use ES6 modules
with the standard syntax, Flow types, and all the other goodies that
we’ve come to expect. A backend build takes about 2.5s on my laptop.

Created by forking the prod configuration to a backend configuration and
trimming it down appropriately.

To test out the new changes, this commit changes `fetchGitHubRepo` and
its driver to use the ES6 module system and Flow types, both of which
are properly resolved.

Test Plan:
Run `yarn backend`. Then, you can directly run an entry point via
```
$ node bin/fetchAndPrintGitHubRepo.js sourcecred example-repo "${TOKEN}"
```
or invoke the standard test driver via
```shell
$ GITHUB_TOKEN="${TOKEN}" src/backend/fetchGitHubRepoTest.sh
```
where `${TOKEN}` is your GitHub authentication token.

Dandelion Mané 0e57b42095 Fetch GitHub repos using the GitHub v4 API (#75)
Summary:
It’s a whole new world of GraphQL! Our parser is now just a GraphQL
query that asks for exactly what we want and dumps it to a file. The
data exposed by the v4 API is also in a much nicer format than that of
the v3 API, so this is pretty much a universal improvement.

Currently, we do not handle pagination. We require that the repository
in question have fewer than a fixed number of issues, and comments per
issue, and reviews per PR, and review comments per PR, and so on. If
this limit is exceeded, the script will fail-fast with a nice error
message. To fix this, we’ll need to write a general-purpose pagination
API that allows traversing cursors at any level of the query.

Paired with @wchargin.

Test Plan:
Run

    $ GITHUB_TOKEN="your_token_here" src/backend/fetchGitHubRepoTest.sh

and verify that it exits with 0. Note that if you change this script’s
repository from `tiny-example-repository` to `sourcecred`, the script
correctly fails and outputs a useful diff.

Add an equality function for `Graph` (#61)
Summary:
We need this for testing graph equality: deep-equality is not sufficient
because two graphs can be logically equal even if, say, two nodes are
added in different orders.

New unit tests added. Run `yarn flow && yarn test`.

Move package json to root (#37)
Reorganize the code so that we have a single package.json file, which is at the root.
All source code now lives under `src`, separated into `src/backend` and `src/explorer`.

Test plan:

- run `yarn start` - it works
- run `yarn test` - it finds the tests (all in src/explorer) and they pass
- run `yarn flow` - it works. (tested with an error, that works too)
- run `yarn prettify` - it finds all the js files and writes to them
