Summary:
This is copied from the Sharness repository’s `test/.gitignore`, and is
also the same as Git’s `t/.gitignore` minus a Git-specific exclusion.
Suggested by @decentralion.
Test Plan:
Run `yarn sharness` and interrupt it (SIGINT) while `make` is running.
Note that `sharness/` now contains a `trash directory.*`, which Git
ignores.

Thanks to #642, it should now be safe to disable the Git plugin, reaping
the benefits described in #628, without causing the cred explorer to
crash (#631).
Test plan:
- `yarn travis --full` passes
- The full cred explorer works:
- Running PageRank does not crash the explorer
- Expanding a pull request does not crash the explorer
- (After clearing state) the weight config doesn't show Git weights
- The filter doesn't show Git nodes
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.

This reverts commit 8c70f03122.
Context: This introduced a serious bug (#631), so we're reverting it to
get the codebase back in a working state. Meanwhile, I'll develop a
principled solution.
Test plan:
I rebuilt the backend, re-loaded a graph, and loaded it in the frontend.
PageRank, the cred explorer, and the weight config all work. Opening a
pull request does not trigger a crash.
See #627 for context.
Removing the Git plugin results in an enormous performance improvement.
In my testing on `metamask/metamask-extension`: before this change, load
took 23s, and PageRank took >9 mins and then crashed. After this change,
load+PageRank took 5s combined.
Test plan: All unit tests pass; loading new data from the CLI works; and
I poked around the UI to make sure there were no spurious references to
the Git plugin.
Note: This does not break backcompat, there's no need to regenerate any
already-loaded data.
Summary:
The `node ./bin/sourcecred.js load` command invokes plugin code by
providing an output directory into which the plugin may store data.
As of this patch, it also provides a cache directory that the plugin may
use to store data that will not be available at runtime. For instance,
the Git plugin might choose to clone the repository herein, or the
GitHub plugin may choose to store partial GraphQL query results to deal
with interruptions. The contract is that the cache directory may be
removed at any time and that the plugin should continue to operate
normally.
Test Plan:
The build script has been updated and tested. Reverting the change to
the build script causes the newly added test to fail. (Each plugin has a
cache directory, though the cache directories are empty for now.)
wchargin-branch: create-plugin-cache
Summary:
Currently, we create the static site and deploy it all at once in
`scripts/deploy.sh`. This commit creates a new script that only builds
the static site. This has the advantage that it is easier/less scary to
change that script (because it can be tested without worrying about
deploying to a local test target), and that we can write automated tests
for it.
Test Plan:
Run `yarn sharness`; note that it completes very quickly. Then, in a
shell with your GitHub token exported, run `yarn sharness-full`. Expect
all tests to pass.
For a sanity check, you can run:
```shell
outdir="$(mktemp -d --suffix .sourcecred-site)"
./scripts/build_static_site.sh --target "${outdir}" \
--cname sourcecred.io \
--repo sourcecred/example-git \
--repo sourcecred/example-github \
;
(cd "${outdir}" && python -m SimpleHTTPServer)
```
and ensure that <http://localhost:8000/> is as expected.
One test case that is not covered is the following: _if_ the actual app
somehow tries to emit a `CNAME` file at root, _and_ our script’s logic
to catch this is broken, then we will not catch this failure. I’ve
tested the logic manually by adding `>"${cname_file}"` after definition
of that variable, but I don’t see a good way to test it automatically,
without adding flags like `--but-actually-emit-cname-too` to the build.
The compound probability of this happening is sufficiently low that this
doesn’t bother me.

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).
