Summary:
Generated with `./scripts/update_snapshots.sh`. This fixes failures
introduced in #1431.
Test Plan:
Running `yarn test --full` now passes. Inspecting the diff shows that
this only includes a compat version number change, which is appropriate.

This commit modifies `discourse/createGraph` so that it finds all of the
same-server Discourse references in Discourse posts, and creates
appropriately typed references edges in response.
The unit tests have been updated with cases for both references that
should exist, and references that shouldn't (e.g. post index out of
bounds, or a reference to the wrong server).
Test plan: `yarn test --full` along with snapshot update.
This is progress towards [Discourse reference and mention detection][1].

This commit adds a `parseLinks` method to a new module,
`plugins/discourse/references`. `parseLinks` allows us to extract the
hyperlinks from `<a>` tags in "cooked" html.
I added `htmlparser2` as a dependency to parse the html. There were a
lot of options to choose from; I chose htmlparser2 because it has a lot
of usage, reasonable performance, and suits our needs. We use this
dependency in a lightweight and local way, so we can always change it
later if needed.
One thing which was a bit odd: I wasn't able to import it using
`import`, and needed a `require` statement instead.
Test plan: Unit tests added; `yarn test` passes.

In #1391, I updated the default alpha, but forgot to regenerate the load
snapshots. This caused a [nightly build failure][1]. This commit fixes
it.

This commit integrates the identity plugin, which was created in #1384.
It does this by adding explicit identity fields to the project
configuration, which are then applied when loading the graph in
`api/load.js`.
The actual integration is quite straightforward.
Test plan: The underlying logic is thoroughly tested; I added one new
test case to verify that it is integrated properly. Since the project
compat has changed, I've updated all the snapshots. Prior to merging
this PR, I will produce one "integration test", using this code to do
identity resolution for a real project (i.e. on the SourceCred instance
itself).
Previously, the `sourcecred scores` command assumed that all users are
GitHub users, and assigned users an id based on their GitHub login.
Now, the command returns information on all users, regardless of which
plugin provided them. As such, we need to identify users differently.
Instead of a string id, they now have an array of address parts. That
array contains all of the parts of their corresponding node address.
For example, the GitHub user `@Beanow` would correspond to the address
array `["sourcecred", "github", "USERLIKE", "USER", "Beanow"]`
As a general convention, the first two components of any node's address
contain information about the plugin that owns that node. The first
component is the owner of the plugin, and the second is the name of the
plugin. Afterwards, the plugin may represent nodes in whatever manner it
sees fit.
Thanks to @Beanow and @vsoch for some feedback and discussion on this
design.
Test plan: Snapshots have been updated. `yarn test` passes.
The PluginDeclaration has all of the information we need to configure
TimelineCred: it knows all the node and edge types, as well as which
node types are user (or scoring) node types.
Therefore, we can replace the ad-hoc config object with a simple array
of plugin declarations. Since the plugins will be saved as part of the
TimelineCred, it means the UI can configure to only show information for
plugins that are actually in scope.
Test plan: `yarn test` passes, and the prototype still works. Snapshots
updated.
This updates the cred computation logic so that we can have multiple
"scoring node types".
Context: Currently, we designate a single node type (GitHub users) as
the scoring node type, and normalize so that all users have 1000 score
in total.
This commit updates the pipeline to admit using more than one prefix for
scoring, meaning that we could have GitHub users, Discourse users, and
more, and still have all users sum to 1000 score.
We will still need to update the frontend so that it will have a user
pane which aggregates across all users.
Test plan: Unit tests updated. `yarn test` passes.
Summary:
Generated with `./scripts/update_snapshots.sh` (with #1360 patched in).
This fixes failures introduced in #1358.
Test Plan:
Running `yarn test --full` now passes. Inspecting the diff (after piping
the old and new snapshots to `jq -S .`) shows that this includes only
additions, which seems appropriate given the precipitating change.
wchargin-branch: fix-1358-failures
This changes how TimelineCred filtering works. Instead of using the
filterTimelineCred module, which includes all nodes matching
filterPrefixes, we now take all nodes matching scorePrefixes and
additionally the top `k` nodes for every other type.
This ensures that we will have the top comments, pull requests, issues,
etc in the UI, without needing to take every single comment or PR or
issue.
Concurrently, the UI is updated so that every type is included in the
filter dropdown.
CHANGELOG has been updated, since this is user facing.
Test plan: `yarn test` passes, snapshots are updated, and I also tested
the UI manually.
TimelineCred computation is implemented as follows:
- Compute Distribution
- Filter it down to specified node types
- Wrap the filtered results into a TimelineCred
I want to change how the filtering works. The new filtering logic will
depend on logic we've already implemented in TimelineCred; therefore
filtering should be done on the TimelineCred object and not separately.
Specifically, I want to be able to filter down to the highest-scored
nodes by type (dependent on the type).
As a first step, I've refactored the interface to TimelineCred so that
the filtering is an implementation detail, i.e. the TimelineCred
constructor doesn't expect objects defined in `filterTimelineCred`.
Test plan: `yarn test` passes after a snapshot update.
This modifies the TimelineCred serialization so that it includes the
CredConfig in the JSON. This means that it's easier to coordinate which
plugins and types are in scope, as the data itself can contain that
information.
Rather than define a new hand-rolled serializer, I just passed the
config directly through for stringification. Unit tests verify that this
still works (round-trip serialization is tested). As an added sanity
check, I generated a new small `cred.json`, and inspected the file via
`cat` to ensure that it's still legible text, and isn't interpreted as a
binary file due to the `NUL` bytes in node addresses.
Every client that previously depended on the `DEFAULT_CRED_CONFIG` now
properly gets its cred configuration from the JSON.
Test plan: Unit tests for serialization already exist. Generated a fresh
`cred.json` file and tested the frontend with it. Also,
`yarn test --full` passes.
PR #1325 introduced a failing snapshot test, which was promptly caught
by @wchargin. This commit fixes it by running
`./scripts/update_snapshots.sh`. Also, I bumped the project JSON version
number, which also should have happened in #1325.
Test plan: `yarn test --full` passes.
Summary:
All links in SourceCred must use the `Link` component, providing either
an external URL `href={…}` or an internal route `to={…}`. Any uses of a
raw `<a>` element for internal routes will incur 404s when the
application is hosted on a non-root path, as is currently the case on
the production website.
The change to `FileUploader` is not strictly necessary, as the link has
no styled text and uses a `data:` URL, but there’s no reason not to.
Fixes#1304.
Test Plan:
Build the static site:
```
scripts/build_static_site.sh --target cred --project sourcecred/example-github
```
Then run `python3 -m http.server` from the repository root directory—not
the `cred/` subdirectory—and navigate to the timeline cred view:
<http://localhost:8000/cred/timeline/sourcecred/example-github/>
Observe that the “(legacy)” link now has the correct styling and
correctly navigates to the legacy mode page when clicked: prior to this
change, it would navigate to a URL without the proper `/cred/` path
prefix, yielding a 404. On the legacy page, verify that the “timeline
mode” link has the same properties.
Then, visit <http://localhost:8000/cred/test/FileUploader/> and verify
that the inspection test still passes.
Added a regression test to catch further such errors. Note that
reverting the code changes in this commit causes the test to fail, and
that running it with `--verbose` prints the problematic files.

I moved sourcecred/example-git{,hub} to the @sourcecred-test org.
This commit fixes the build given that move.
I've realized that in #1233 I in-advertently made some Git tests that
depend on a snapshot un-updateable. I'm going to compound on that slight
technical debt by skipping the tests that depended on that snapshot. I
recognize and accept that I'll need to pay this down when I resuscitate
the git plugin.
Test plan: `yarn test --full`.
This commit swaps usage over to the new implementation of `cli/load`
(the one that wraps `api/load`) and makes changes throughout the project
to accomodate that we now track instances by Project rather than by
RepoId.
Test plan: Unit tests updated; run `yarn test --full`. Also, for safety:
actually load a project (by whole org, why not) and verify that the
frontend still works.
The scores are lightly processed from their internal representation.
Example usage:
```
$ yarn backend;
$ node bin/sourcecred.js load sourcecred/sourcecred
$ node bin/sourcecred.js scores sourcecred/sourcecred > scores.json
```
The data structure is as follows:
```js
export type NodeOutput = {|
+id: string,
+totalCred: number,
+intervalCred: $ReadOnlyArray<number>,
|};
export type ScoreOutput = Compatible<{|
+users: $ReadOnlyArray<NodeOutput>,
+intervals: $ReadOnlyArray<Interval>,
|}>;
```
Test plan: I added sharness tests at `sharness/test_cli_scores.t`.
In the past, we've used javascript tests for CLI commands. However,
those are pretty time-consuming to write, and are less robust than
simply running the command from bash. Check the snapshot for a sense of
what the new data format looks like. Also, the snapshot updater now
updates this snapshot too.
Relevant for #1047.
Thanks to @Beanow for feedback on the output format and design.
Thanks to @wchargin for help in code review.
This fixes a build error in test_build_static_site.t.
It's been masked by a lot of ENOMEM issues I've been having in the full
build, so a few failures had actually had a chance to accrue:
- Fixes an issue wherein loading the sourcecred/example-git repo would
error (on failure to normalize scores, because there was no user
activity). Fixed it pretty crudely by adding an issue to that
repository.
- Fixes an issue where a deprecation warning caused the
build_static_site build to fail. We now permit that particular warning.
- Updates the example load snapshot.
Test plan: `yarn test --full` passes once again.
This commit disables the Git plugin by removing it from the default list
of plugins to load, or to display in the frontend.
Rationale: The git plugin doesn't currently add very much to cred
quality. Git commits have edges to their parent, which isn't a very
meaningful relationship for cred purposes. We'll want to re-enable the
Git plugin once we're ready to support e.g. file and directory level
cred tracking.
I've skipped a block of tests around the git analysisAdapter. (I intend
to deprecate the analysisAdapters, so skipping the tests seemed
preferrable to updating them). I also updated our sharness test for
catching test files without a proper describe block, so that it won't
error on skipped blocks.
Test plan: `yarn test --full` passes. Loading a new repository and
inspecting it in the frontend gives consistent results. There are no
references to Git plugin weights in the frontend, now that corresponding
nodes are not available.
This updates the graph `Node` type to include a string description.
The description should be a brief (ideally oneline) string giving
context on what the node is. All planned frontends will support
markdown, so linking to context (e.g. linking to the issue corresponding
to an ISSUE type node) is supported.
This commit updates the Git and GitHub plugins to use the new
description field.
Test plan: `yarn test --full` passes, and I've inspected snapshots and
made sure they look reasonable.
This commit modifies the Graph class so that it permits dangling edges;
that is to say, edges whose src or dst are not present in the graph.
Dangling edges may be directly added to the graph, or existing edges may
become dangling if their src or dst is removed.
This change is prerequisite to #1136; if we require that nodes have
metadata, we should also make it possible to add edges to nodes that
don't yet exist, as the plugin creating an edge may not have access to
the full metadata needed to add the node.
To support this change, there is now an `isDanglingEdge` method on the
graph, which reports whether or not the edge is dangling. Also,
`Graph.edges` requires that the client make an explicit choice on
whether dangling edges are desired. This ensures that we do not
accidentally include dangling edges in a case where they are
inappropriate (e.g. creating a Markov chain) or accidentally discard
dangling edges when they are needed (e.g. when merging or serializing).
The Graph's invariant checker has been updated to reflect the new
semantics.
The Graph compat version has been bumped, since this is a break in
backwards compatibility.
Note that this commit does not change the behavior of any plugins; that
is to say, no plugins create dangling edges (yet).
Test plan: The advanced graph test case has been updated to include
dangling edges. The tests for Graph, PagerankGraph, and
GraphToMarkovChain have been updated. `yarn test --full` passes.
This will allow timeline cred (#862) to do a better job of flowing cred
across reaction edges. (Very old reactions should not be moving a lot of
present-day cred.)
Test plan: Inspected snapshot changes.
I added `mentionsAuthorReference` based on an untested hypothesis that
they would be useful. With the passage of time, I've never seen any
evidence that they actually improve cred socres (their impact seems
negligible), and they add complexity.
In the future, "go-fishing" style heuristics like this should not merge
unless they are of clearly demonstrated value. Also, it would be better
to add stuff like this via a standalone plugin rather than in the core
GitHub logic.
Undoes #806.
Test plan: `yarn test`
As of the timeline cred work, I'm shifting emphasis away from raw
PageRank results, in favor of timeline pagerank results. As such,
there's no need to have load save the regular pagerank results on
creation.
As of #1136, there will be no need for timestampMap, as that data will
be present directly in the graph. As the timeline cred UI will depend on
the full graph for analysis, let's save the graph instead.
Test plan: `yarn test` and snapshot inspection.
At present, the Git commit node type lives in a strange state of shared
responsibility between GitHub and Git. The Git plugin is nominally
responsible for it, but its render method tries to show a hyperlink to
GitHub -- which is awkward for many reasons, including that the same Git
commit could have multiple hyperlinks on GitHub.
This commit resolves that issue by separating the existing commit type
into two: the Git Commit type, which is owned by the Git plugin and
doesn't have hyperlinks or any fancy GitHub metadata, and the GitHub
Commit, which is owned by the GitHub plugin, corresponds to a unique
database id in GitHub, and has a corresponding GitHub url.
The two commits are connected by a CorrespondsToCommit edge type, which
links from the GitHub commit to the corresponding Git commit.
This is necessary for #1136, as if we want to make descriptions a part
of the graph payload, we need for descriptions to be unique for a given
address--and descriptions are only unique if we identifiy each GitHub
commit pointer as a separate address.
Test plan: The unit testing in this part of the codebase is light, so I
verified that the frontend work as expected for `sourcecred/sourcecred`
and `sourcecred/research`. The new node type and edge type appear
properly in the UI, the GitHub commits are connected to their Git
counterparts, etc.
This modifies `sourcecred load` so that it saves timestamp information
for all of the loaded plugins in a single aggregated map.
This is quite convenient, as it saves consumers of timestamp information
from needing to worry about the (rather hacky) implementation whereby
the data is fed from each adapter. Instead, consumers can just load the
timestamp map. This will also make it much easier to use timestamp info
in the research codebase.
Test plan: The timestampMap module has testing around generating the map
from the adapter and nodes, writing it, and reading it.
I haven't added any testing to the `load` CLI command. I think it would
be redundant as the updated snapshot test reveals that the map is
getting serialized properly.
Tests pass, and I have inspected the snapshot
As SourceCred has evolved, we've grown more and more snapshot tests that
are not included in Jest. The GitHub plugin has two ad-hoc snapshot
tests, the Git plugin has one, and the sharness test suites have one.
This makes it difficult to keep track of where to update snapshots when
core changes are made. To fix this, I've added a script,
`scripts/update_snapshots.sh`, which updates snapshot tests across the
project.
Test plan: I removed existing snapshots across the codebase, ran the
snapshot tester, and they correctly regenerated.
Thanks to @wchargin for [catching it].
[catching it]: https://github.com/sourcecred/sourcecred/issues/1151#issuecomment-494256526
Generated this change via:
```
$ yarn backend
$ (cd sharness; UPDATE_SNAPSHOT=1 ./test_load_example_github.t -l)
```
Test plan: `yarn test --full`, excluding the known (local-only) failure
described in #1151
Modifies the Git plugin so that we now track commit author dates.
Similar to in #1152, they are encoded in MsSinceEpoch.
Test plan: `yarn test --full` passes, except for the pre-existing
failure discussed in #1151.
Thanks to @s-ben for a conversation which motivated these changes.
Updates github schema to include createdAt timestamps, and then updates
the RelationalView to provide those timestamps as MsSinceEpoch.
I added createdAt timestamps to Repos, Issues, Pulls, Reviews, and
Comments, as these correspond to GitHub graph nodes where I think
time-based filtering is relevant. I didn't add them to Users, Reactions,
or Commits. Reactions, because they correspond to edges not nodes. (We
could consider doing the time filtering on edges too, but I'd rather
keep it simple for now.) Commits, because they're owned by a different
plugin. Users, because... in a certain sense the user identity is
timeless, the time factoring is mostly so we can evaluate how users'
cred varies over time.
Anyway, it will be easy to add more fields later if we need them.
Test plan:
- Inspect snapshot changes
- Ran `yarn test --full`
- Its only failure is pre-existing, per #1151
Thanks to @s-ben for some motivation and discussion about this change.
This commit updates the `sourcecred load` command so that it also
automatically runs PageRank on completion.
The implementation is slightly hacky, in that it prints two sets of
task status headers/footers to console, for reasons described in a
comment in the source code. The user-visible effect of this hack can
be seen below:
```
❯ node bin/sourcecred.js load sourcecred/example-github
Starting tasks
GO load-git
GO load-github
DONE load-github
DONE load-git
Overview
Final result: SUCCESS
Starting tasks
GO run-pagerank
DONE run-pagerank
Overview
Final result: SUCCESS
```
It would be good to clean this up, but for now I think it's acceptable.
Note that it is not safe to assume that a PagerankGraph always exists
for repos that are included in the RepoIdRegistry. The repo gets added
to the registry before the pagerank task runs. Consumers that are
loading the `PagerankGraph` can just check that the file exists, though.
Test plan: I've added unit tests that verify that the right tasks are
generated. Most importantly, the snapshot of the results of `sourcecred
load` now include a snapshotted pagerank graph.
(The snapshot was updated via `UPDATE_SNAPSHOT=1 yarn test --full`.)
Further progress on #967.
Updating github example data with support
for 🚀 and 👀 reaction types.
This follows #1068 and @decentralion updating
the archived repo with the new reaction types.
`src/plugins/github/fetchGithubRepoTest.sh -u`
(as @decentralion suggested) updated `example-github.json`
`yarn unit` caught two tests with failing snapshot
tests (`createGraph.test` and `relationalView.test`), so
I updated those with `yarn unit -u`
`yarn test -full` caught a failing snapshot test
at `sharness-full`, resolved by updating the
snapshot in `view.json.gz` with
`UPDATE_SNAPSHOT=1 yarn test --full`.
Thanks to @wchargin for the [explanation] on how
to resolve that issue.
[explanation]: https://github.com/sourcecred/sourcecred/pull/1077#pullrequestreview-196805017
**Test Plan:**
`yarn test --full` is passing.
Additionally, the commands:
```sh

[ -f "${filepath}" ] && # sanity check
diff -u \
<(git show "HEAD:${filepath}" | gzip -d | jq .) \
<(gzip -dc "${filepath}" | jq .) \

Summary:
Our registry was defined to simply be a list of IDs. This is
insufficiently flexible; we want to be able to annotate these IDs with,
e.g., last-updated times (#989). This commit wraps the entries in a
simple object, updating clients appropriately.
Test Plan:
- Run `node ./bin/sourcecred.js load sourcecred/example-github` with a
repository registry in the old format, and note that it errors
appropriately.
- Run `yarn build` with a repository registry in the old format, and
note that it errors (“Compat mismatch”).
- Delete the old registry and re-run the `load` command. Note that it
runs successfully and outputs a registry. Run `yarn build`; note
that this works.
- Load data for two repositories. Run `yarn start`. Note that the list
of prototypes still works, and that you can navigate to and render
attributions for individual project pages.
- Verify that `yarn test --full` passes.
wchargin-branch: repo-id-registry-metadata
We added a configurable cred feedback url on the theory that we would
create a separate discourse post to collect feedback for each project in
particular.
We've now realized that no one is using this, so it's just vestigial
complexity now. So I'm removing the logic for configuring the feedback
url on a per-project basis.
Instead, we will always link to a Google form for collecting feedback.
Test plan: `yarn test --full` passes, and I manually checked the links.
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.
Summary:
Fixes#955. Our test runner does run `yarn backend` before Sharness
tests, but it builds the backend applications into a temporary directory
rather than squashing the repository backend (which is good!). The test
script has learned about this directory.
Test Plan:
Run `rm -rf ./bin && yarn test --full`, which fails before this commit
and passes after it.

Summary:
Resolves#800. The newly added test takes about 2ms per file.
Test Plan:
Run `yarn sharness`, and note that it passes.
Then, edit (say) `src/main/test.js` to change the top-level describe
block from `"cli/main"` to something else, or to remove it altogether.
Re-run `yarn sharness` and note that it fails with a helpful message:

```
wchargin-branch: describe-test
Summary:
Lots of tests need the output of `yarn backend`. Before this commit,
they tended to create it themselves. This was slow and wasteful, and
also could in principle have race conditions (though in practice usually
tended not to).
This commit updates tests to respect a `SOURCECRED_BIN` environment
variable indicating the path to an existing directory of backend
applications.
Closes#765.
Test Plan:
Running `yarn test --full` passes.
Prepending `echo run >>/tmp/log &&` to the `backend` script in
`package.json` and running `yarn test --full` results in a log file
containing only one line, indicating that the script really is run only
once.
wchargin-branch: deduplicate-backend
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!
0
```
wchargin-branch: fix-build-test-quoting
Summary:
This change should have happened in #768. However, I didn’t catch it
then because `yarn test --full` passes even before this commit, despite
the expected error being clearly wrong! It turns out that a very sneaky
bug conspires with this one to result in the test passing no matter what
kinds of warnings `yarn backend` may output. This bug is fixed in #772.
Test Plan:
Observe that the error message is now correct by comparing against the
source in `config/RemoveBuildDirectoryPlugin.js`. Then, apply #772 and
note that `yarn test --full` still passes, but does not pass when #772
is applied and this change is reverted.
wchargin-branch: fix-expected-error-message
Summary:
In #715, I used Bash arrays for convenience. Our tests should run under
POSIX `sh` (as on Travis and standard GNU/Linux). This patch
reimplements the check using only POSIX features.
Fixes#752.
Test Plan:
As is, `yarn test --full` passes on GNU/Linux and macOS(+GNU coreutils).
Change the glob from `main.*.js` to `*.js` and note that running the
test emits an error:
```
fatal: multiple main bundles found:
build_output/output_NO_REPOS/static/js/main.6307f660.js
build_output/output_NO_REPOS/static/js/ssr.e92af807.js
```
Change the glob from `main.*.js` to `nope.*.js` and note that running
the test emits an error:
```
fatal: no main bundle found
```
Revert the glob to normal and note that all tests run and pass.
(To run tests, `./test_build_static_site.t --chain-lint --long -v` from
the `sharness/` directory.)
wchargin-branch: posix-bundle-check
Test Plan:
Running `./test_build_static_site.t --long -v` no longer detects the
feedback URL as unsafe. (Prior to this commit, it emitted a message to
this effect.) The build is still broken on Linux for other reasons, but
works on macOS or any other system where `sh` resolves to Bash.
As a regression test, the “potentially unsafe argument” warning has been
made to actually fail the test case. To verify this, remove `:` from the
list of `unusual_chars`, run the test, and note that it fails outright.

Summary:
We store the relational view in `view.json.gz` instead of `view.json`,
taking advantage of the isomorphic `pako` library for gzip encoding and
decoding.

not been applied):

Closes#750.
Test Plan:
Comparing the raw old version with the decompressed new version shows
that they are identical:
```
$ <~/tmp/sourcecred/data/sourcecred/example-github/github/view.json \
> shasum -a 256 -
63853b9d3f918274aafacf5198787e18185a61b9c95faf640a1e61f5d11fa19f -
$ <~/tmp/sourcecred/data/sourcecred/example-github/github/view.json.gz \
> gzip -dc | shasum -a 256
63853b9d3f918274aafacf5198787e18185a61b9c95faf640a1e61f5d11fa19f -
```
Additionally, `yarn test --full` passes, and `yarn start` still loads
data and runs PageRank properly.

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.
