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
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.

Don’t erase the `bin/` folder in CI (#317)
Summary:
Previously, our CI script would run `yarn backend`, which has the
side-effect of erasing the `bin/` directory. By itself, this is not
great, but not awful. However, this frequently triggers a race condition
in Prettier, causing the `check-pretty` step of the build to fail. (More
details: https://github.com/prettier/prettier/issues/4468.)
This patch changes the CI script to build the backend scripts into a
temporary directory.
Test Plan:
Before applying this patch: `yarn backend` and then `yarn travis`. If
this consistently causes a Travis failure due to `check-pretty`, then
your machine can reproduce the race condition that we‛re trying to
eliminate. (Otherwise, you can try creating a bunch more Git history…
I’m not really sure what to say. It is a race condition, after all.)
Then, apply this patch, and repeat the above steps; note that the error
no longer occurs, and that the build output is to a temporary directory.

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.
