Test Plan:
Note that `yarn backend; node bin/sourcecred.js help` still works.
Note that `git grep -i oclif` returns no results.
Rejoice.
wchargin-branch: remove-oclif
Summary:
This commit changes the CLI to use the code in `cli` instead of `oclif`.
A subsequent commit will remove the dependency on OClif altogether.
Resolves#580.
Test Plan:
Note that `yarn backend; node bin/sourcecred.js help` works. Note that
the documentation in the README is still correct.

Summary:
We store the relational view in `view.json.gz` instead of `view.json`,
taking advantage of the isomorphic `pako` library for gzip encoding and
decoding.

not been applied):

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

> shasum -a 256 -
63853b9d3f918274aafacf5198787e18185a61b9c95faf640a1e61f5d11fa19f -

63853b9d3f918274aafacf5198787e18185a61b9c95faf640a1e61f5d11fa19f -
```
Additionally, `yarn test --full` passes, and `yarn start` still loads
data and runs PageRank properly.
wchargin-branch: gzip-relational-view
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...

```
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.

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.
wchargin-branch: createRelativeHistory
Summary:
In addition to the obvious benefit of having a favicon, this gets rid of
a 404 Not Found error on our home page, tremendously boosting our hacker
cred.
Test Plan:
The favicon is displayed in both `yarn start` and the static site (as a
result of the build script). The added build test fails before this
change.
wchargin-branch: add-favicon
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.
wchargin-branch: remove-sw
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).
wchargin-branch: add-sharness
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.)
wchargin-branch: clean-actual-build-directory
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.
wchargin-branch: reorganize-test-command
Test Plan:
Run `yarn start` and note that everything checks out.
Run `yarn build && (cd build/ && python -m SimpleHTTPServer)` and note
that everything checks out, except that the static assets are of course
not included in the build.
wchargin-branch: webpack-replace-scripts
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.
wchargin-branch: webpack-clean-build
Summary:
In addition to a routine libdef update, we also need to work around a
particularly nasty new bug in Flow, which requires `any`-casts that are
even more unsafe than usual. That said, I think that it’s worth that
cost to remain up to date with Flow, so that we can amortize future such
issues.
Test Plan:
Running `yarn travis --full` passes.
wchargin-branch: upgrade-flow-v0.76.0
This required adding a [files property] to the package.json,
otherwise oclif started complaining.
Test plan: I manually tested both CLI commands, and they seem fine.
[files property]: https://docs.npmjs.com/files/package.json#files
This commit is a good faith effort to separate our dependencies (code
that SourceCred app or CLI require to run) from devDependencies (all
other deps) in our package.json.
We don't have any actual dependents, so it's hard to test this
distinction. Hence, it's a good faith effort.
Test plan:
`rm -r node_modules && yarn && yarn travis` works.
Also add config/jest/setupJest.js so we can configure jest-fetch-mock
Test plan: I have verified that mocked fetch works as expected in a
downstream commit.
Summary:
Pending the resolution of brigand/babel-plugin-flow-react-proptypes#201,
we’re removing this plugin from our build, because it results in
incorrect code generation. We’ll be happy to add it back if the bug is
fixed.
Test Plan:
Fingers crossed.
wchargin-branch: remove-bpfrpt
Summary:
We plan to use this to more intelligently extract references from GitHub
text content. See #432.
Test Plan:
In a Node shell, running
```js
const cm = require("commonmark");
var parser = new cm.Parser();
var ast = parser.parse("Hello\nworld");
var html = new cm.HtmlRenderer({softbreak: " "}).render(ast);
console.log(html);
```
prints `<p>Hello world</p>`.
wchargin-branch: commonmark
Summary:
We’re not mandating anything about coverage right now, but by making it
easier to track coverage perhaps people will organically become more
motivated to write good tests.
Test Plan:
Run `yarn coverage`, and then open `coverage/lcov-report/index.html`.
wchargin-branch: coverage
Summary:
This just slows down commits by a few seconds. We `check-pretty` in
Travis, so this doesn’t actually catch anything—and, anecdotally, it has
never caught anything for me because I automatically run `prettier` on
save and also (almost) always run Travis before pushing.
Test Plan:
Run `git commit --amend --no-edit` and note that it is now fast!
wchargin-branch: no-lint-on-commit
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.)
wchargin-branch: upgrade-flow-v0.72.0
This commit adds [oclif] as a command-line framework. It is successfully
integrated with webpack.
[oclif]: https://github.com/oclif/oclif
Usage:
`yarn backend` to build the cli.
`node bin/sourcecred.js` to launch the CLI and see usage
`node bin/sourcecred.js example` for one example command
`node bin/sourcecred.js goodbye` for another example command
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.
wchargin-branch: target-node
Summary:
We want to change this configuration so that our compilation of backend
applications can target latest Node. This commit forks the current
configuration so that we can modify it easily.
Test Plan:
Both `yarn start` and `yarn travis` work. The generated backend
applications work, too.
wchargin-branch: fork-babel-config
Setup following directions from [webpack-node-externals]
[webpack-node-externals]: https://www.npmjs.com/package/webpack-node-externals
This unblocks #210.
Test plan: `yarn backend` still succeeds, and the binary scripts still
work. The resultant binaries are much smaller, as seen below (note build
time is the same).
before:
```
❯ yarn backend
yarn run v1.5.1
$ node scripts/backend.js
Building backend applications...
Compiled successfully.

21.48 KB bin/createExampleRepo.js
17.71 KB bin/loadAndPrintGitRepository.js
Build completed; results in 'bin'.
Done in 4.46s.
```
after:
```
❯ yarn backend
yarn run v1.5.1
$ node scripts/backend.js

```
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
real 0m12.427s
user 0m13.752s
sys 0m0.804s
```
A 50% savings is not bad at all—and the raw time saved should only
improve from here on, as the individual steps start taking more time.
wchargin-branch: custom-ci
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.
wchargin-branch: wip-git-create-graph
Test Plan:
Run `yarn lint` and `yarn travis` and observe success. Add something
that triggers a lint warning, like `const zzz = 3;`; re-run and observe
failures.
wchargin-branch: lint
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`
https://www.npmjs.com/package/lodash.sortby
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:

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.

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.

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.

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.
