Summary:
GitHub has an undocumented node limit on the number of IDs that can be
provided to the top-level `nodes` connection. This is silly, because we
can just spread the IDs over multiple identical connections. This commit
implements the logic to do so.
Test Plan:
Create some queries that use `nodes(ids: ...)` to fetch varying numbers
of objects:
```shell
id="MDEwOlJlcG9zaXRvcnkxMjAxNDU1NzA="
nodes() {
n="$1"
ids="$(yes "$id" | head -n "$n" | jq -R . | jq -sc .)"
printf 'nodes(ids: %s) { __typename }' "$ids"
}
query() {
printf '{ '
for num; do
printf 'nodes_%s: %s ' "$num" "$(nodes "$num")"
done
printf '}'
}
```
Note that the query given by `query 101` results in an error…
```json
{
"data": null,
"errors": [
{
"message": "You may not provide more than 100 node ids; you provided 101.",
"type": "ARGUMENT_LIMIT",
"path": [
"nodes_101"
],
"locations": [
{
"line": 1,
"column": 3
}
]
}
]
}
```
…but the query given by `query 98 99` happily returns 197 node entries.
wchargin-branch: mirror-paginate-own-data
Summary:
Fixes#903. We already ignore Markdown code syntax (backticks), but
prior to this commit we treated the contents of all HTML elements,
including `<code>`, as normal text. As of this commit, `<code>` elements
are stripped entirely. Other HTML elements, like `<em>`, are unaffected.
Test Plan:
Unit tests added. Also, load data for `ipfs/js-ipfs-block-service`, and
observe in the UI that PR `#36` (Update aegir to version 9.0.0) no
longer has any outward references.
wchargin-branch: markdown-html-code
Summary:
Git only learned `--date=format:...` in Git 2.6.0. Some old Docker
images have older versions of Git. It’s not too much work to reimplement
this particular bit of functionality, so this commit does so.
Test Plan:
Install Git 2.1.4 (as used on CircleCI): from the Git repository for
Git itself, run:
git checkout v2.1.4
make
make install
Watch `yarn test --full` pass. Before this commit, `yarn unit` failed.
wchargin-branch: env-support-git-2.1.4
Summary:
Our environment-stripping logic used in `config/env.js` to read the
current Git state included stripping the `PATH` environment variable.
This had the effect that the system Git executable would always be used
in preference to a user-installed version.
Test Plan:
Run `/usr/bin/git --version`, and then install a different version of
Git. (For instance, check out an old tag, then `make && make install`
from the `git/git` repository.) Then, add
```js
console.log(execFileSync("git", ["--version"], {env}).toString());
```
to `getGitState` in `config/env.js`, and run
NODE_ENV=development node ./config/env.js
Note that this prints the version of the system Git before this change,
and the user Git after this change.
Alternately, local-install a version of Git earlier than 2.6.0, and note
that `yarn unit` now _fails_ because the `--date=format:…` syntax is not
known to such versions of Git. Prior to this commit, the tests would
pass as long as the system Git were more recent.
wchargin-branch: env-git-path
Summary:
CircleCI seems fast.
This config file copied from the one suggested by CircleCI, with the
following modifications: Node version changed from 7.10 to 8.12.0;
commented-out MongoDB dependency removed; capitalization error in header
comment fixed.
Test Plan:
Per the CircleCI instructions, merge this PR and then turn on the
project.
wchargin-branch: circleci-config
This modifies the `nodeDescription` code for the Git plugin so that when
given a Git commit, it will hyperlink to that commit on GitHub. It does
this by looking up the corresponding `RepoId`s from the newly-added
`commitToRepoId` field in the `Repository` (#884).
Per a [suggestion in review], rather than hardcoding the GitHub url
logic in the Git plugin, we provide them via a `GitGateway`.
[suggestion in review]: https://github.com/sourcecred/sourcecred/pull/887#issuecomment-424059649
When no `RepoId` is found, it errors to console and does not include a
hyperlink. When multiple `RepoId`s are available, it chooses to link to
one arbitrarily. (In the future, we could amend this behavior to add
links to every valid repo). This behavior is tested.
Test plan:
I ran the application on newly-generated data and verified that it sets
up commit hyperlinks appropriately. Also, see unit tests.
Summary:
An update step is now roughly as simple as:
_updateData(postQuery(_queryFromPlan(_findOutdated())))
(with some option/config parameters thrown in).
This makes progress toward #622.
Test Plan:
Unit tests included. They are light, because these functions are light.
They still retain full coverage.
wchargin-branch: mirror-full-pipeline
Summary:
These typenames are often superfluous, but sometimes they are useful.
For instance, we might want to fetch the same data for `User`s, `Bot`s,
and `Organization`s, but still differentiate which kind of node we
fetched from an `Actor` union reference. Similarly, many timeline events
may have similar signatures (like, “issue closed” vs. “issue reopened”).
Test Plan:
Existing unit tests have been updated; run `yarn unit`.
wchargin-branch: mirror-extract-typenames
Summary:
The `extract` method lets you get data out of a mirror in a structured
format.
The mirror module now contains all the plumbing needed to provide
meaningful value. Remaining to be implemented are some internal
porcelain and a public method to perform an update step.
This makes progress toward #622.
Test Plan:
Comprehensive unit tests included, with full coverage; run `yarn unit`.
wchargin-branch: mirror-extract
Motivated by my desire for `.toMatchInlineSnapshot()`. Really we just
need and updated typing file for this, but I upgraded `jest` too to just
get us in a clean state.
Commit generated via:
```
yarn add --dev jest
flow-typed install jest@23.6.0
```
Test plan: `yarn test`
Test Plan:
Note that the nav links are now a lighter color, except when `:active`
(e.g., when you’re holding down the mouse button).
wchargin-branch: remove-visited
Summary:
This reestablishes harmony in light of #882.
Test Plan:
Existing unit tests suffice; run `yarn unit`.
wchargin-branch: mirror-query-plan-connection-object-typename
Summary:
This commit adds internal functions to (a) emit a GraphQL query to fetch
data for own-data of an object, and (b) ingest the results of said query
back into the database.
The API and implementation differ from the connection-updating analogues
introduced in #878 in that the query for own data is independent of an
object’s ID: it depends only on the object’s type. This affords us more
flexibility in composing queries.
As described in a internal documentation comment, values are stored in
the database in JSON-stringified form: we cannot use the obvious raw SQL
values, because there is no native encoding of booleans (`0`/`1` is
conventional), and we need to distinguish them from other data types.
There are other ways to solve this problem. Notably:
1. We could take inspiration from OCaml: encode stronger static types
and a simpler runtime representation. That is, we could change the
schema field types from simply “primitive” to the various specific
primitive types. Then, when reading data out from the database, we
could reinterpret the values appropriately.
2. We could take advantage of the fact that we are not using all of
SQLite’s data types. In particular, we do not store anything as a
binary blob, so we could encode `false` as a length-0 zeroblob and
`true` as a length-1 zeroblob, for instance. Again, when reading
data out from the database, we would reinterpret the values—but in
this approach we would not need an explicit schema from the user.
For now, we take the easiest and simplest approach just to get ourselves
off the ground. We can easily move to the second option described above
later.
This commit makes progress toward #622.
Test Plan:
Unit tests included, with full coverage. While these tests check that
the GraphQL queries are as expected, they cannot check that they are
actually valid in production. To check this, follow the instructions in
the added snapshot test.
wchargin-branch: mirror-own-data-updates
Summary:
This will enable us to style links consistently across our application.
Our previous link colors for base and `:visited` were so similar that I
didn’t actually realize that they were different. In this change, I’ve
kept the same base color, and selected a more contrasting `:visited`
color. I also added an `:active` color, which is good for usability
(color chosen via <http://paletton.com/>’s “triad” suggestion).
Example screenshot, with active, visited, and base links:
![Screenshot as in this commit][img-underline]
I also considered implementing the link underlines with `border-bottom`
instead of `text-decoration` (an oft-touted suggestion that has always
smelled fishy to me, but [the W3 does it][w3], so I guess it’s okay).
That would look like this:
![Screenshot with `border-bottom` underlines][img-border]
…but I did not do so ([rationale in a comment on #890][rationale]).

[rationale]: https://github.com/sourcecred/sourcecred/pull/890#issuecomment-424146773
We can certainly change these decisions later—that’s one of the purposes
of having this abstraction—so I’m not inclined to bikeshed on them too
much in this commit.
Implementation adapted from:
<80263b190e/src/components/Link.js>
Test Plan:
Check that `<a>` elements and React Router link elements are used only
in `Link` and snapshots:
```
$ git grep --name-only -Fw '<a'
src/app/Link.js
src/assets/logo/discourse_512.png
src/plugins/github/__snapshots__/render.test.js.snap
$ git grep '"react-router"' | grep 'Link'
src/app/Link.js:import {Link as RouterLink} from "react-router";
src/app/Link.test.js:import {Link as RouterLink} from "react-router";
src/app/createRelativeHistory.test.js:import {Router, Route, Link} from "react-router";
src/app/withAssets.test.js:import {IndexRoute, Link, Router, Route} from "react-router";
```
Check that the primary color now appears in just one spot:
```
$ git grep -i 0872a2
src/app/Link.js: ...colorAttributes("#0872A2"),
```
Then, run `yarn start` and click all the links. Note in particular that
the SVG icons in the header have the correct colors in the active state
as well as the base state.
wchargin-branch: app-link
Summary:
As <https://github.com/sourcecred/sourcecred/pull/883/files#r219648511>.
It is somewhat unfortunate that this mixes a command with a query, but
the concession is acceptable in this instance, I think.
Test Plan:
Existing unit tests suffice, retaining full coverage.
wchargin-branch: mirror-register-node-field-results
Summary:
This helpful utility is already used in some test code, and will shortly
be used in main code. @decentralion suggested factoring it out in
<https://github.com/sourcecred/sourcecred/pull/883#discussion_r219647781>.
Test Plan:
Unit tests included, with full coverage; run `yarn unit`.
wchargin-branch: mirror-make-update-helper
Summary:
These were completely wrong; my bad.
[The docs][1] list `source` and `returnsData` but not `database`.
I include the latter only for consistency with `Transaction`, and will
consider removing them both as they are technically undocumented (though
not underscore-named, so it’s not clear-cut).
[1]: https://wchargin.github.io/better-sqlite3/api.html#properties-1
Test Plan:
At a Node console:
```js
> require("better-sqlite3")(":memory:").prepare("BEGIN")
Statement {
returnsData: false,
source: 'BEGIN',
database:
Database {
inTransaction: false,
open: true,
memory: false,
readonly: false,
name: ':memory:' } }
```
wchargin-branch: flow-better-sqlite3-statement-properties
This modifies the Git `Repository` data structure so that for every
commit, we track the `RepoId`s of repos containing that commit. This way
we will be able to do things like hyperlink to the right url for that
commit.
`loadRepository` has been modified to set the initial `repoId`.
`mergeRepository` has been updated to ensure that it concatenates the
`repoId`s properly.
Tests were added for both cases.
The example-git snapshot has been updated accordingly.
Test plan: `yarn test --full`
This modifies `core/repoId` so that `repoIdToString` returns not a
`string`, but an opaque subtype of `string` called `RepoIdString`.
This allows us to store stringified `RepoId`s (which is useful whenever
we want value-not-reference semantics, like for use as a map key)
while still maintaining a type assertion that the strings, in fact,
represent valid `RepoId`s.
Test plan: A unit test verifies that it's a flow error to cast a string
to a `RepoIdString`.
Summary:
Almost every GitHub connection has nodes of an object type, like `User`
or `IssueComment`. But a few have nodes of union type, including
`IssueTimelineItemConnection` (which we will likely want to query), and
those require special handling. This commit adds susupport for such
connections.
Analysis to determine which connections have non-object elements:
<https://gist.github.com/wchargin/647fa7ed8d6d17ae2e204bd098104407>
Test Plan:
Unit tests modified appropriately, retaining full coverage.
The easiest way to verify the snapshot is probably to copy the raw
contents (everything inside the quotes) into `/tmp/snapshot`, then run:
```shell
$ sed -e 's/\\//g' </tmp/snapshot >/tmp/query # Jest adds backslashes
$ jq -csR '{query: ., variables: {}}' </tmp/query >/tmp/payload
$ ENDPOINT='https://api.github.com/graphql'
$ AUTH="Authorization: bearer ${SOURCECRED_GITHUB_TOKEN}"
$ curl "$ENDPOINT" -X POST -H "$AUTH" -d @- </tmp/payload >/tmp/result
```
and then execute the JQ program mentioned in the comment in the test
case, and verify that it prints `true`.
wchargin-branch: connection-of-union
We have a core type called `Repo`, but it really is an identifier to a
repo, rather than being a repo itself. This is confusing since we have a
data type called `Repository` which actually represents the data in a
repository. I've renamed `Repo` to `RepoId` for clarity.
Test plan: `yarn test --full` passes. Running the frontend passes after
wholly regenerating the sourcecred data directory.
This modifies how commits are displayed in the cred explorer. Rather
than printing the full hash, we now print a short hash followed by the
summary.
Test plan:
Snapshot is updated, also I tested it by running SourceCred on a real
repository.
Summary:
This commit changes the `Issue` type of the schema used in the `mirror`
tests to have fields a faithful subset of those in the actual GitHub
schema. The tests are self-contained, so this is not strictly required.
However, it is convenient, because it means that we can snapshot a query
that can actually be posted to GitHub.
Test Plan:
Running `yarn unit mirror` suffices for the code change. The GitHub
schema docs at <https://developer.github.com/v4/object/issue/> indicate
that each of `id`, `url`, `author`, `repository`, `title`, and
`comments` is a valid field.
wchargin-branch: mirror-test-schema
This modifies the Git Commit type to includea short hash and a oneline
summary, and modifies `loadRepository` so that we actually get that
data.
The example-git repository has been updated to include a commit with
leading whitespace and a pipe in the summary, to ensure that these are
respected.
Test plan: Observe that the snapshot is updated, and the updates are
correct. `yarn test --full` passes.
Summary:
This commit adds internal functions to (a) emit a GraphQL query to fetch
data for a particular connection, and (b) ingest the results of said
query back into the database.
This commit makes progress toward #622.
Test Plan:
Unit tests included, with full coverage. While these tests check that
the GraphQL queries are as expected, they cannot check that they are
actually valid in production. To check this, follow the instructions in
the added snapshot test.
wchargin-branch: mirror-connection-updates
In #873 I removed the data types for trees, blobs, and entries, but
neglected to remove the address related code. This commit corrects that
mistake. Some test cases in other modules have been removed because the
failure is now structurally impossible, e.g. it is not possible that we
would provide a non-commit address to the GitHub plugin, because
non-commit addresses do not exist.
Test plan: `yarn test --full` passes.
Summary:
This function finds all objects whose own data has not been updated
since a given time, and all connections whose entries have not been
updated since that time.
Note that this is scoped to the entirety of the database. In #622,
I discussed using a recursive common table expression to identify only
those transitive dependencies of the root. I think that this is overkill
for the `_findOutdated` method: you’ll usually want to update everything
in the database. Don’t worry—the cool recursive query will still be used
in the `extract` function. :-)
This commit makes progress toward #622.
Test Plan:
Unit tests added, with full coverage; run `yarn unit`.
wchargin-branch: mirror-findoutdated
This modifies the behavior when loading the Git plugin so that it
serializes the Repository as well as the graph. This will allow us to
get extra information, like the commit headline, to the Git plugin in
the frontend.
As an added bonus, we can now refactor `loadRepositoryTest` to depend on
`sourcecred.js load` rather than `loadAndPrintRepository`. As this was
the only use for `loadAndPrintRepository`, we can safely delete it. This
improves our test quality because it means we are also testing the
actual CLI behavior.
Note that the switch from using `stringify` to `json.tool` for
pretty-printing has resulted in a trivial diff in the snapshot.
Test plan: `yarn test --full` passes.
In #627, I made a case for removing all trees and blobs from the cred
graph. The issue was that the data was bloated and noisy, and did not
provide much value in its current form. This commit follows on that by
actually removing the code from the codebase (rather than keeping it
unused).
I want to delete this code because I believe:
1. It is unlikely to see further use in its current form (because
collecting the entire Git tree structure is just too noisy for our
purposes)
2. In the event that we do need it, reviving it will not be too
difficult (because it is all quite locally scoped to the Git plugin).
3. Keeping unused code increases ongoing maintenance + development
costs, and I'd like to bias towards keeping the codebase simple and
lean.
In the event that a future contributor is reviving this code and finds
it a pain, I pre-emptively apologize to you.
Test plan:
`yarn test --full` passees.
Summary:
This function informs the GraphQL mirror of the existence of an object,
specified by its global ID and its concrete typename (“concrete” meaning
“object type”—like `User`, not `Actor`).
The function will be called extensively internally as more objects are
discovered while traversing the graph, but also needs to be exposed as a
public entry point: a client needs to call this function at least once
to register the root node of interest. A typical client workflow, once
all of #622 is implemented, might be:
1. Issue a standalone GraphQL query to find the ID of a root node, like
a GitHub repository: `repository(owner: "foo", name: "bar") { id }`.
2. Call `registerObject` with the ID found in the previous step.
3. Instruct the mirror to recursively update all dependencies.
4. Extract data from the mirror.
As of this commit, steps (1) and (2) are possible.
This commit makes progress toward #622.
Test Plan:
Unit tests included, with full coverage; run `yarn unit`.
wchargin-branch: mirror-registerobject
This commit adds a utility method, `mergeRepository`, which can merge
multiple Git repository data structures. `loadGitData` has been updated
to create a merged repository and then subsequently generate a graph
from it.
Test plan:
New unit tests were added. `yarn test --full` passes. Loading a project
and viewing its git data in the cred explorer works.
I wanted to add two new flowtype lint rules. However, as seen in #853
and #854, these rules don't work very well. As such, I'm giving up on
those two and removing the TODOs.
Test plan: n/a
Summary:
The actual constraints for bound parameters are too complicated to
express within Flow. This commit changes the type definitions from one
approximation to another, simpler one. Neither approximation is likely
to cause many problems in practice, either in terms of spurious errors
or spurious lacks of error. (The failure mode for the new formulation is
having multiple dictionaries of binding values, which would pass Flow
but quickly raise a `TypeError` at runtime.)
The reason for the change is that it makes the method definitions
considerably simpler, in a way that is likely to avoid other problems
with Flow. In particular, this removes method overloads and the need for
parameter disambiguation.
I fix a typo while in the area.
Test Plan:
Note that the following file typechecks:
```js
// @flow
import Database from "better-sqlite3";
const db = new Database(":memory:");
const stmt = db.prepare("BEGIN"); // SQL text doesn't matter
stmt.run();
stmt.run(null, 2, "three", new Buffer(Array(4)));
stmt.run(+false);
stmt.run(1, {dos: 2}, 3); // the binding dictionary can go anywhere
stmt.run({a: 1}, {b: 2}); // this will fail at runtime (TypeError)
// $ExpectFlowError
stmt.run(false); // booleans cannot be bound
// $ExpectFlowError
stmt.run({x: {y: "z"}}); // named parameters are not recursive
```
All but the last two success cases (lines 9 and 10) would also have
passed before this change.
wchargin-branch: flow-better-sqlite3-bound-parameters-simplify
Summary:
It’s useful to add this simple function now because the rest of the
commits required to implement #622 will want to use it extensively in
test code. Actual clients of the API will not need to use it, because
the concept of “updates” is an implementation detail: clients will
always provide simple timestamps.
Test Plan:
Unit tests included, with full coverage; run `yarn unit`.
wchargin-branch: mirror-createupdate
This commit modifies the plugin adapter's `nodeDescription` method so
that it may return a React node.
This enables the GitHub plugin's `nodeDescription` method to include
hyperlinks directly to the referenced content on GitHub. This makes
examining e.g. comment cred much easier.
I've also made two other changes to the descriptions:
- Pull requests diffs now color-encode the additions and deletions
- Descriptions for comments and reviews no longer include the authors
The Git plugin's behavior is unchanged.
Test plan:
I loaded a large repository in the cred explorer and verified that
exploring comments and pulls and issues is much easier. The descriptions
are as expected for every category of node. Snapshot tests updated.
Fixes#590.
Summary:
SourceCred officially supports Node v8.x.x, so Travis should be testing
against that version of Node.
This fixes a cron-only, Travis-only failure. The test for the build
script asserts that stderr only contains some known expected messages.
On Node v10, which Travis was using, there is an additional deprecation
message due to <https://github.com/yarnpkg/yarn/issues/5477>.
Test Plan:
To see that this fixes the current cron-only build failure, add the
`--full` argument to the `test` script in `package.json`, and push the
resulting tree to Travis. Note that it runs `sharness-full`, which
passes.
wchargin-branch: travis-node-8
Summary:
Sharness tests use temporary directories under the `sharness/`
directory, which sometimes contain build output, which includes
JavaScript files. This creates a flaky failure in `yarn test`: if
`sharness` creates a file then `check-pretty` can complain about it.
Test Plan:
None.
wchargin-branch: prettier-ignore-sharness
Summary:
In #339, we attempted to configure Travis to email us on build failure.
But we misread [the docs]: the emails need to be preceded by a hyphen.
[the docs]: https://docs.travis-ci.com/user/notifications#configuring-email-notifications
This is understandable because the Travis documentation renders the
critical hyphen with `#999` against a background of `#f5f2f0` at 12px,
which has a contrast ratio of only 2.55, failing WCAG 2.0 categorically.
Test Plan:
Fingers crossed.
wchargin-branch: travis-email-config
Summary:
This was changed in the v4.0.0 release of `better-sqlite3`:
<https://github.com/JoshuaWise/better-sqlite3/pull/61>
Test Plan:
Create the following test file, and note that it fails to typecheck
before this change (on two counts) but passes after:
```js
// @flow
import Database from "better-sqlite3";
const db = new Database(":memory:");
db.prepare("CREATE TABLE foo (id)").run();
const insert = db.prepare("INSERT INTO foo (id) VALUES (?)");
insert.run(1);
insert.run(2);
const retrieve = db.prepare("SELECT id FROM foo").pluck();
console.log("Old way:");
try {
// $ExpectFlowError
retrieve.each((x) => void console.log(x));
} catch (e) {
console.log("Failed (good):", String(e));
}
console.log();
console.log("New way:");
for (const value of retrieve.iterate()) {
console.log(value);
}
```
Also, run the test with `NODE_ENV=development babel-node src/test.js`,
and note that it outputs:
```
$ NODE_ENV=development babel-node src/test.js
Old way:
Failed (good): TypeError: retrieve.each is not a function
New way:
1
2
```
wchargin-branch: flow-better-sqlite3-iterator
Summary:
Some clients want to write
const primitivesTableName = _primitivesTableName(typename);
which they cannot if the function is also called `primitivesTableName`,
due to ECMAScript shadowing semantics.
Test Plan:
Running `yarn flow` suffices; running `yarn unit` really suffices.
wchargin-branch: mirror-rename-primitivestablename
Summary:
Each change provides real value, by either testing a plausible happy
path that simply was not tested previously, or by adding an
`empty`-assertion to a switch against a discriminated union type.
Test Plan:
For the snapshot change relating to the query formatter, note that
Prettier formats the changed portion of the snapshot in the same way, by
visiting <https://prettier.io/playground> and setting the parser to
"graphql". (Prettier in general agrees with the stringification defined
by this module, except for commas and spacing, for which we don’t bother
to generate impeccably pretty output.)
Run `yarn coverage` and note that the coverage of the whole `graphql`
package is 100% on all axes.
wchargin-branch: graphql-coverage
Summary:
This simplifies and clarifies the code with no observable change.
Test Plan:
Existing unit tests suffice; run `yarn unit`.
wchargin-branch: mirror-use-schemainfo
Summary:
This is mostly useful not for computational efficiency, but for ease of
implementation: there end up being multiple places where we want to find
(say) the primitive fields on an object, and having to go through the
whole iterate-and-switch-and-push process repeatedly is annoying.

Unit tests included, with full coverage; run `yarn unit`.
wchargin-branch: mirror-schema-info
Summary:
This commit augments the `Mirror` constructor to turn the provided
GraphQL schema into a SQL schema, with which it initializes the backing
database. The schema is roughly as originally described in #622, with
some changes (primarily: we omit `WITHOUT ROWID`; we add indexes; we
store `total_count` on connections; and we use milliseconds instead of
seconds for epoch time).
Test Plan:
Unit tests included, with full coverage; run `yarn unit`.

According to the [jest docs], setting `maxWorkers=4` can substantially
improve performance on CI.
This commit sets `maxWorkers=4` when running `yarn unit` as a part of
`yarn test`. Based on my local testing (see data below), this improves
performance locally in addition to the expected performance improvement
on travis.

[jest docs]: https://jestjs.io/docs/en/troubleshooting
Our continuation-fetching code failed to properly get continuations for
pull request review comments, because it was only asking for more
reactions on `"IssueComment"` fragments. This caused the
`ensureNoMorePages` function to properly throw an error rather than
proceding with incomplete data.
This commit fixes the root cause by splitting
`continuationsFromComment`into `continuationsFromReviewComment` and
`continuationsFromIssueComment`. (Pull and issue comments are both
considered 'IssueComment's.) The example-github repository has been
updated to include 10 reactions to a single review comment; the
example-data was updated in this commit, and all reactions have been
loaded.
I've also added a `console.error` statement in `ensureNoMorePages`. This
only triggers when the program is about to fail, and it's useful for
debugging.
Test plan: `yarn test --full` passes.

Summary:
Fixes#850.
Test Plan:
Regression test added; it fails before the change and passes after it.
Also, running `node ./bin/sourcecred.js load wchargin/mt` (which is a
GitHub repository with no commits) now successfully loads the
repository. (The cred explorer fails to process it, because it tries to
normalize across GitHub users, of which there are none, but this is a
known limitation and is unrelated.)
