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:
We never use the `node ./bin/sourcecred.js start` command. This command
contains an Express server to combine the static files with the build
output, which duplicates the logic in our Webpack config, which we
actually use (with `yarn start`). Once we actually want the command line
entry point to be a useful tool for end users, we can consider
reimplementing it the right way, whatever that may be. Until then, it’s
simply one more thing to keep in sync.
Test Plan:
Running `yarn test --full` passes; the `load` CLI command still works;
running `yarn start` still works.
wchargin-branch: remove-start
Summary:
This subtree has no effect on the new build process; it contains only
stale code.
Test Plan:
Running `yarn test --full` passes. Running `yarn build` and running an
HTTP server on the result indicates the expected behavior, as does
running `yarn start`. A quick `git grep public` finds no amok results.
wchargin-branch: remove-public
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:
This removes the hard-coded route data from the Webpack config,
replacing it with the list of paths exported by the route data module.
Test Plan:
Note that the output of `yarn build` is identical before and after this
change: namely,
```shell
$ find build -exec shasum -a 256 {} + | shasum -a 256
7610a61f8a977f1d8edd849fc81256ca15f41f366e5fdb4b59a5d5ce37d6d58e
```
wchargin-branch: non-hard-coded-route-data
Summary:
Some of the code here is adapted from my site (source available on
GitHub at wchargin/wchargin.github.io). It has been improved when
possible and made worse when necessary to fit into our existing build
system with minimal churn.
As of this commit, there remain the following outstanding tasks:
- Use a non-hardcoded list of paths in static site generation router.
This is not trivial. We have the paths nicely available in
`routes.js`, but this module is written in ES6, and transitively
depends on many files written in ES6 (i.e., the whole app). Yet
naïvely it would be required from a Webpack config file, which is
interpreted as vanilla JavaScript.
- Add `csso-loader` to minify our CSS. This is easy.
- Add unit tests for `dedent`. (As is, it comes from my site
verbatim. I wrote it. dmnd’s `dedent` package on npm is insufficient
because it dedents arguments as well as the format string, which is
incorrect at least for our purposes.)
- Link in canonical static data for the site.
- Rip out the whole build system and replace it with my build config,
which is orders of magnitude saner and less bad. (By “the whole
build system” I mostly mean `webpack.config.{dev,prod}.js`.)
Test Plan:
```shell
$ yarn backend
$ yarn build
$ node ./bin/sourcecred.js start

The bridge introduced in #448 has now served its purpose, and may be
deconstructed. This implements the first part of the last step of the
plan described in that pull request.
Paired with @decentralion.
Test Plan:

`node bin/sourcecred.js start-v3` works
`yarn travis --full` passes
Paired with @wchargin
Summary:
This could also be moved into the bridge directory, but this way is
marginally easier, and it doesn’t really matter in the end.
Test Plan:
`yarn backend` followed by `node bin/sourcecredV3.js start-v3` works.
wchargin-branch: start-v3
The `load` command replaces `plugin-load`. By default, it loads data for
all plugins, and does so in parallel using execDependencyGraph. If
passed the optional `--plugin` flag, then it will load data just for
that plugin.
As an implementation detail, when loading all plugins, load calls itself
with the plugin flag set.
Usage:
`node bin/sourcecred.js load repoOwner repoName`
Test plan:
Tested by hand; I blew away my SourceCred directory and then loaded the
example-github repository.
Summary:
Our build system doesn’t make it easy to have two separate React
applications, which we would like to have for the V1 and V3 branches.
Instead, we’ll implement a bridge to maintain compatibility.
The plan looks like this:
1. Change the app from pointing to V1 to pointing to a bridge
2. Move the router into the bridge and move the V1 app from the `/`
route to the `/v1` route (e.g., `/v1/explorer`)
3. Add a V3 app under the `/v3` route
4. ???
5. Delete the V1 app and remove it from the bridge
6. Delete the bridge and move the V3 app from the `/v3` route to `/`
This commit implements Step 1.
Test Plan:
To verify that the bridge is in fact showing, apply
```diff
diff --git a/src/bridge/app/index.js b/src/bridge/app/index.js
index 379e289..72e784c 100644
--- a/src/bridge/app/index.js

+ <V1App />

and say “hello” back to the app.
wchargin-branch: bridge
Summary:
This provides a command-line entry point `load-plugin-v3` (which will
become `load-plugin` eventually), which fetches the GitHub data via
GraphQL and saves the resulting `RelationalStore` to disk.
A change to the Babel config is needed to prevent runtime errors of the
form `_callee7` is not defined, where `_callee7` is a gensym that is
appears exactly once in the source (in use position, not definition
position). I’m not sure exactly what is causing the error or why this
config change fixes it. But while this patch may be fragile, I don’t
think that it’s likely to subtly break anything, so I’m okay with
pushing it for now and dealing with any resulting breakage as it arises.
Paired with @decentralion.
Test Plan:
Run `yarn backend`, then run something like:
```
node bin/sourcecredV3.js load-plugin-v3 \
sourcecred example-github --plugin github
```
Inspect results in `SOURCECRED_DIR/data/OWNER/NAME/github/view.json`,
where `SOURCECRED_DIR` is `/tmp/sourcecred` by default, and `OWNER` and
`NAME` are the repository owner and name.
This example repository takes about 1.1 seconds to run. The SourceCred
repository takes about 45 seconds.
wchargin-branch: cli-load-plugin
Summary:
Due to oclif’s structure, this entry point shares its `commands`
directory with that of the V1 entry point. We’ll therefore add commands
like `start-v3` as we go.
Test Plan:
`yarn backend` works, and `node bin/sourcecredV3.js start` launches the
V1 server.
wchargin-branch: v3-cli
Summary:
Many files are unchanged. Some files have had paths updated, or new
build/test targets added.
The `types.js` file includes payload type definitions. These are
technically independent of the graph abstraction (i.e., nothing from V1
is imported and the code all still works), but it of course implicitly
depends on the V1 model. For now, we include the entirety of this file,
just so that we have a clean copy operation. Subsequent commits will
strip out this extraneous code.
Suggest reviewing with the `--find-copies-harder` argument to Git’s
diffing functions.
Test Plan:
Running `yarn travis --full` passes. Running
./src/v3/plugins/git/demoData/synchronizeToGithub.sh --dry-run
yields “Everything up-to-date”.
wchargin-branch: git-v3-copy
This commit copies the following logic necessary for downloading GitHub
data into v3. Minimal changes have been made to accomodate the new path
structure.
Test plan:
- Manually ran plugins/github/fetchGithubRepoTest.sh and verified that
it can correctly pass and fail
- Added the v3 github repo test to `yarn travis --full`
- Ran `yarn travis --full` and it passed
Paired with @wchargin
We want to reset some of our basic assumptions, and make `Graph` into a
pure graph implementation, rather than a hybrid graph and key-value
store.
This is a substantial rewrite, so we want to start from scratch in a v3/
directory and pull code into v3 as necessary. So that we can do this in
a relatively clean fashion, we're first moving the v1 and v2 code into
their own directories.
Paired with @wchargin
Test plan: Travis, and `yarn backend`, `node bin/sourcecred.js start`.
Note that `yarn backend` and `node bin/sourcecred.js start` both use the
v1 versions. We'll migrate those (by changing paths.js) to v3 when
appropriate.
Summary:
This way, our frontend can talk to a backend that can read from the
filesystem (among other things).
Paired with @decentralion.
Test Plan:
```
$ yarn backend
$ SOURCECRED_DIRECTORY=/tmp/srccrd yarn start
$ # verify that the browser looks good
$ mkdir /tmp/srccrd
$ echo hello >/tmp/srccrd/world
$ curl localhost:3000/api/v1/data/world
hello
$ curl localhost:4000/api/v1/data/world
hello
```
wchargin-branch: webpack-proxy
- Fix accidental string-to-NaN coercion in ensureSlash
- Don't dynamically require package.json; to determine public url, just
use the environment variable or "/"
Test plan: `yarn start` and travis still work
This commit executes a micro-refactor to move all top-level app setup
code out of src/plugins/artifact/editor and into src/app. The observed
behavior from `yarn start`, which is to show the artifact editor, is
unchanged.
Summary:
We need a way for our web applications to interact with data on the
filesystem. In this commit, we introduce a webserver that serves
statically from two directory trees: first, the result of a live-updated
Webpack build; second, the SourceCred data directory.
Test Plan:
Run `yarn backend` and `node ./bin/sourcecred.js start`. When ready,
navigate to the server’s root route in a web browser. Note that a nice
React app is displayed. Then, change something in that React app source.
Note that the server console displays Webpack’s update messages, and
that refreshing the page in the browser renders the new version of the
app. Finally, visit
/__data__/graphs/sourcecred/example-github/graph.json
in the browser to see the graph for the example repository, assuming
that you had generated its graph previously.
wchargin-branch: start
This script ensures that either //@flow or //@no-flow is present in
every js file. Every existing js file that would fail this check has
been given //@no-flow, we should work to remove all of these in the
future.
Test plan:
I verified that `yarn travis` fails before fixing the other js files,
and passes afterwards.
Our SourceCred CLI tool now ipmlements printCombinedGraph and
cloneAndPrintGitGraph, but with more principled implementations and
interfaces :)
Test plan:
`yarn travis --full` passes, so I didn't delete any needed test infra.
Summary:
This commit implements the `sourcecred` command-line utility, which has
three subcommands:
- `plugin-graph` creates one plugin’s graph;
- `combine` combines multiple on-disk graphs; and
- `graph` creates all plugins’ graphs and combines them.
As an implementation detail, the `into.sh` script is very convenient,
avoiding needing to do any pipe management in Node (which is Not Fun).
When we build for release, we may want to factor that differently.
Test Plan:
To see it all in action, run `yarn backend`, and then try:
```
$ export SOURCECRED_GITHUB_TOKEN="your_token_here"
$ node ./bin/sourcecred.js graph sourcecred sourcecred
Using output directory: /tmp/sourcecred/sourcecred

```
The `node sourcecred.js graph` command takes 9.8s for me.
(The salient point of the last command is that the two small graphs have
node count adding up to the node count of the big graph. Incidentally,
we are [almost][1] at a nice round number of nodes in the GitHub graph.)

wchargin-branch: cli
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
`printCombinedGraph` loads and prints a cross-plugin combined
contribution graph for a given GitHub repository.
It is a simple executable wrapper around `src/tools/loadCombinedGraph`.
Example usage:
`node bin/printCombinedGraph.js sourcecred example-git $GITHUB_TOKEN`
`cloneAndPrintGitGraph` clones a git repository, and generates a Git
object graph for that repository.
This can be run as follows:
```
yarn backend;
node bin/cloneAndPrintGitGraph sourcecred example-git
```
This commit also adds two utility modules:
* `cloneAndLoadRepository` , which clones a Git repository to a tmpdir,
parses the `Repository` data out, and then cleans up.
* `cloneGitGraph`, which calls `cloneAndLoadRepository` and `createGraph`
Test plan: These don't fit well into our CI, because they require
network access to clone repositories from GitHub. I verified that the
functions work via the demo script above.
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
Summary:
Two reasons for this. First, we want tests to be able to operate on this
data without having to generate repositories via `git(1)`. (Doing that
is slow, and requires a Git installation, and makes it less clear that
the tests are correctly isolated/provides more surface area for
something to go wrong.) Second, in general plugins will need a canonical
source of test data, so setting/continuing this precedent is a good
thing.
Test Plan:
Observe that the old Jest snapshot must be equivalent to the new JSON
one, because the test criterion in `loadRepository.test.js` changed and
the test still passes. Then, run `loadRepositoryTest.sh` and note that
it passes; change the `example-git.json` file and note that the test
fails when re-run; then, run the test with `--updateSnapshot` and watch
it magically revert your changes.
wchargin-branch: check-in-git-repo
Summary:
We’ll use this to create the repositories on disk and then push them to
GitHub.
Test Plan:
Generate both kinds of repository, and check out the SHAs:
```shell
$ yarn backend
$ node bin/createExampleRepo.js /tmp/repo
$ node bin/createExampleRepo.js --submodule /tmp/repo-submodule
$ node bin/createExampleRepo.js --no-submodule /tmp/repo-no-submodule
$ # (first and third lines do the same thing)
$ git -C /tmp/repo rev-parse HEAD
677b340674bde17fdaac3b5f5eef929139ef2a52
$ git -C /tmp/repo-submodule rev-parse HEAD
29ef158bc982733e2ba429fcf73e2f7562244188
$ git -C /tmp/repo-no-submodule rev-parse HEAD
677b340674bde17fdaac3b5f5eef929139ef2a52
```
Then, note that these SHAs are expected per the snapshot file in
`exampleRepo.test.js.snap`.
wchargin-branch: create-example-repo-command
* Make GitHub capitalization consistent within code
We now never capitalize the H in GitHub within variable or function
names. We still capitalize it in comments or user facing strings.
Test plan:
Unit tests, the fetchGithubRepoTest.sh, and
`git grep itHub` only shows comment lines and print statements.
* Fix William's klaxon
Summary:
We’ll now start creating the artifact plugin. A large part of this will
be the user interface, including a GUI. For now, our build system just
builds a single React app, so we’re cannibalizing the main explorer to
serve this purpose.
Paired with @dandelionmane.
Test Plan:
The following still work:
- `yarn test`
- `yarn start`
- `yarn build; (cd build; python -m SimpleHTTPServer)`
wchargin-branch: repurpose-react-app-as-artifact-editor
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.
wchargin-branch: webpack-backend
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
