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.

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).

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.

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.
