Summary:
This patch fixes a particularly sneaky bug. Our test script contains a
literal backtick inside single quotes. This is generally not a problem,
because backticks inside single quotes do nothing. But the contents of
the single quotes are interpreted as Bash by our test runner, and at
that time the single quotes are expanded to a command substitution.
Therefore, `grep` is invoked as if writing
grep -e "warning: running $(yarn backend)"
at the CLI. This will actually invoke `yarn backend`!
The magnificent aspect of this bug is that it both makes the test script
slower by about ten seconds _and_ completely and silently defeats the
assertion in which it’s contained. The output of `yarn backend` contains
several blank lines. Therefore, one of the literal patterns to `grep`
contains a blank line. This causes `grep` to match _every_ line in the
error file, regardless of whether it is one of the intended messages.
This patch is the 666th PR to SourceCred. In my opinion, it deserves
this dubious honor.
Test Plan:
Note that `yarn test --full` works, but fails if one of the expected
error message patterns is deleted or munged.
Confirm the behavior by prepending `echo backend >>/tmp/log &&` to the
`yarn backend` script in `package.json`, noting that the resulting log
file contains four lines before this patch and two lines after it.
(Don’t forget to delete/clear the log file before invocations.)
Confirm the behavior of `grep` by writing:
```shell
$ printf 'things went wrong!\n' >err
$ printf 'wat\n\nwot\n' >patterns
$ grep -vF -e "okay" -e "warn: `cat patterns`" err; echo $?
1
$ printf 'wat\nwot\n' >patterns # no empty line
$ grep -vF -e "okay" -e "warn: `cat patterns`" err; echo $?
things went wrong!

SourceCred
SourceCred creates reputation networks for open-source projects. Any open-source project can create its own cred, which is a reputational metric showing how much credit contributors deserve for helping the project. To compute cred, we organize a project’s contributions into a graph, whose edges connect contributions to each other and to contributors. We then run PageRank on that graph.
To learn more about SourceCred’s vision and values, please check out our website and our forum. One good forum post to start with is A Gentle Introduction to Cred.
For an example of SourceCred in action, you can see SourceCred’s own prototype cred attribution.
Current Status
We have a prototype that can generate a cred attribution based on GitHub interactions (issues, pull requests, comments, references, etc.). We’re working on adding more information to the prototype, such as tracking modifications to individual files, source-code analysis, GitHub reactions, and more.
Running the Prototype
If you’d like to try it out, you can run a local copy of SourceCred as follows. First, make sure that you have the following dependencies:
- Install Node (tested on v8.x.x).
- Install Yarn (tested on v1.7.0).
- Create a GitHub API token. No special permissions are required.
- For macOS users: Ensure that your environment provides GNU coreutils. See this comment for details about what, how, and why.
Then, run the following commands to clone and build SourceCred:
git clone https://github.com/sourcecred/sourcecred.git
cd sourcecred
yarn install
yarn backend
export SOURCECRED_GITHUB_TOKEN=YOUR_GITHUB_TOKEN
node bin/sourcecred.js load REPO_OWNER/REPO_NAME
# this loads sourcecred data for a particular repository
yarn start
# then navigate to localhost:8080 in your browser
For example, if you wanted to look at cred for ipfs/js-ipfs, you could run:
$ export SOURCECRED_GITHUB_TOKEN=0000000000000000000000000000000000000000
$ node bin/sourcecred.js load ipfs/js-ipfs
replacing the big string of zeros with your actual token.
You can also combine data from multiple repositories into a single graph.
To do so, pass multiple repositories to the load command, and specify an “output name” for the repository.
For instance, the invocation
node bin/sourcecred.js load ipfs/js-ipfs ipfs/go-ipfs --output ipfs/meta-ipfs
will create a graph called ipfs/meta-ipfs in the cred explorer, containing the combined contents of the js-ipfs and go-ipfs repositories.
Early Adopters
We’re looking for projects who want to be early adopters of SourceCred! If you’re a maintainer of an open-source project and would like to start using SourceCred, please reach out to us on our Discord or our forum.
