Summary:
We want to remove the repository selector dropdown on the cred explorer
homepage and instead render a separate web page for each project. To do
this, we need to know which pages to render statically. We choose to
ingest this information from the state of the repository registry at
build time.
This commit adds an environment variable `REPO_REGISTRY` whose contents
are the stringified version of the repository registry, or `null` if
SourceCred has been built for the backend. This variable is defined with
Webpack’s `DefinePlugin`, so any code bundled by Webpack can refer to it
via `process.env.REPO_REGISTRY` both on the server and in the browser.
Paired with @wchargin.
Test Plan:
Sharness tests modified; running `yarn test --full` suffices.
Currently version is located in `homepage/`, which doesn't make much
sense, since it's versioning the whole project.
We move it to core.
Test plan: `yarn test --full`
Summary:
Fun facts:
- `new Date().getDay()` does not return the day of the month. It
returns the day of the _week_ as an integer `0 ≤ n ≤ 6`.
- `new Date().getDate()` returns the day of the month from 1 to 31.
- `new Date().getMonth()` really does return the month, but _this_ one
is zero-based!
All this to say, my implementation in #901 was a bit flawed.
Why didn’t I notice at the time? I wrote and tested the change on
2018-10-01, which was a Monday, so both `getDay()` and `getDate()` were
in fact `1`. As for me failing to notice that `getMonth()` was off by
one—well, sometimes I’m very dumb.
Test Plan:
```shell
$ NODE_ENV=development node -e '
> require("./config/env");
> console.log(process.env.SOURCECRED_GIT_STATE);
> '

wchargin-branch: env-fix-date-formatting
Summary:
Git only learned `--date=format:...` in Git 2.6.0. Some old Docker
images have older versions of Git. It’s not too much work to reimplement
this particular bit of functionality, so this commit does so.
Test Plan:
Install Git 2.1.4 (as used on CircleCI): from the Git repository for
Git itself, run:
git checkout v2.1.4
make
make install
Watch `yarn test --full` pass. Before this commit, `yarn unit` failed.
wchargin-branch: env-support-git-2.1.4
Summary:
Our environment-stripping logic used in `config/env.js` to read the
current Git state included stripping the `PATH` environment variable.
This had the effect that the system Git executable would always be used
in preference to a user-installed version.
Test Plan:
Run `/usr/bin/git --version`, and then install a different version of
Git. (For instance, check out an old tag, then `make && make install`
from the `git/git` repository.) Then, add
```js
console.log(execFileSync("git", ["--version"], {env}).toString());
```
to `getGitState` in `config/env.js`, and run
NODE_ENV=development node ./config/env.js
Note that this prints the version of the system Git before this change,
and the user Git after this change.
Alternately, local-install a version of Git earlier than 2.6.0, and note
that `yarn unit` now _fails_ because the `--date=format:…` syntax is not
known to such versions of Git. Prior to this commit, the tests would
pass as long as the system Git were more recent.
wchargin-branch: env-git-path
Summary:
This is a follow-up to #746, wherein we exposed our fixed `env` to the
backend applications. We now extend that environment so that it can also
access the user’s runtime environment—i.e., the native values of
`process.env`.
(This is in contrast to the frontend bundles `main.js` and especially
`ssr.js`, where this is not and should not be the case: the environment
must be fixed at build time.)
Test Plan:
Add to the top of `async run()` in `src/cli/commands/load.js`:
```js
console.log(require("../../app/version").VERSION_SHORT);
console.log(process.env.AT_RUNTIME);
```
Run `yarn backend` and `AT_RUNTIME=wat node bin/sourcecred.js load`.
Ensure that the version number and the string `wat` are both printed.
(Before this patch, the string `undefined` would be printed instead of
`wat`.)
wchargin-branch: backend-extensible-env
Summary:
We can now set, at build time, a URL to be displayed at the top of the
prototype, encouraging users to provide feedback. If the URL is not
provided, it defaults to the appropriate topic on the SourceCred
Discourse instance.
The result looks like this:

Test Plan:
Unit tests added to `yarn sharness-full` and `yarn unit`.
You can run `yarn start` to see the message with the default URL, or
`SOURCECRED_FEEDBACK_URL=http://example.com/ yarn start` to specify a
custom URL.
wchargin-branch: feedback-url
Summary:
The version number displayed in the application now displays much more
specific information. It now lists the Git commit from which the build
was constructed, and will identify whether we have accidentally deployed
a development instance (which would be slow) or an instance with
uncommitted changes (which would be bad).
The version information is computed during the initialization of the
Webpack config. For development, this means that it is computed when you
run `yarn start`, and not updated thenafter. If the stale information
presents actual confusion, we would need to backport Webpack 4’s support
for runtime values in `DefinePlugin` to Webpack 3 (or upgrade Webpack
by a major version).
Test Plan:
The logic for `GitState` and `Environment` has existing tests. With both
a clean tree and a dirty tree, run `yarn start` and build the static
site, and check that the resulting versions are correct.
wchargin-branch: use-rich-version-types
Summary:
We don’t use or want these. Injecting an arbitrary family of variables
from the client’s host environment seems like a Bad Idea.
Test Plan:
The usual `yarn start`, static site, and `yarn test --full` still work.
wchargin-branch: remove-reactapp-vars
Summary:
Cargo-culting `reduce` doesn’t make something “functional” or “good”;
forcing a `for`-loop into a `reduce` with impure callback is abhorrent.
Test Plan:
Into `config/stopship.js`, write:
```js
console.log(JSON.stringify(require("./env")()));
```
Then run `NODE_ENV=test node config/stopship.js` before and after this
commit and note that the output is identical.
wchargin-branch: simplify-getClientEnvironment
Summary:
Now that the main functionality of #643 has been implemented, we no
longer have any use for the “public URL” property. In fact, its presence
is actively harmful, as it suggests that the gateway may be known before
runtime, which is confusing and false.
Closes#643.
Test Plan:
Running `yarn start` works. Building the static site works.
Invoking `git grep -i 'public.\?url'` finds no matches.
Also, `yarn test --full` passes.
wchargin-branch: remove-public-url
It was doing some clever array construction that added possible booleans
to the array, then filtered them out. To make the typing simpler for
Flow's inspection, we now only put string elements in the array.
Test plan: `yarn travis --full` passed, and the CLI still works.
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.
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
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
