The explorer no longer ships with a set of default plugins. (This made
an inappropriate dependency from explorer/ to plugins/, and complicated
explorer's contract as a generic component.) Instead, the homepage
module is responsible for choosing the plugins to display on the
homepage.
Test plan: `yarn test --full` passes, and `yarn start` reveals a
functioning homepage and prototype.
Summary:
Prior to this commit, running `yarn test full` (instead of `--full`)
would silently behave the same way as `yarn test`. This is misleading.
It now fails.
Test Plan:
Run `! yarn test full && yarn test --full`.
wchargin-branch: test-validate-arguments
Currently version is located in `homepage/`, which doesn't make much
sense, since it's versioning the whole project.
We move it to core.
Test plan: `yarn test --full`
Summary:
This was used for ad hoc testing of the Mirror module before it was
integrated into SourceCred. We haven’t kept it up to date with schema
changes, and it is no longer needed: you can just run `sourcecred load`.
This was also the only untested code in the `graphql/` package, so it is
nice to remove it.
Test Plan:
Running `yarn test --full` passes.
wchargin-branch: remove-mirror-demo
Summary:
This adds object IDs to the GitHub GraphQL blacklist such that the
`twbs/bootstrap` repository can be loaded.
Ingesting the Mirror-extracted data into the RelationalView yields the
warnings
```
IssueComment[MDEyOklzc3VlQ29tbWVudDEwNTI4Mzk4Ng==].reactions: unexpected null value
IssueComment[MDEyOklzc3VlQ29tbWVudDI0NTQ3OTM3OA==].reactions: unexpected null value
IssueComment[MDEyOklzc3VlQ29tbWVudDMwNDE4NzIzMg==].reactions: unexpected null value
```
because we have nulled out these `Reaction`s in their enclosing
connections. This is expected.
Test Plan:
Run `yarn backend` and `node ./bin/sourcecred.js load twbs/bootstrap`.
Run `yarn start` and note that the cred attribution renders properly.
(Loading the GitHub data may take an hour or two. The resulting SQLite3
database is 172MB. Ingesting it into the `RelationalView` still takes
just a few seconds, and the cred attribution is rendered quickly.)
wchargin-branch: github-use-blacklists
Summary:
This enables us to deal with GraphQL remotes that violate their contract
guarantees and provide a node of the wrong type. An instance in which
the GitHub GraphQL API does this is documented here:
<https://gist.github.com/wchargin/a2b8561b81bcc932c84e493d2485ea8a>
A Mirror cache is only valid for a fixed set of blacklisted IDs. This is
necessary to ensure consistency. If the set of blacklisted IDs changes,
simply remove the existing database and download again from scratch.
Test Plan:
Unit tests added, with full coverage.
wchargin-branch: mirror-blacklist
Summary:
We currently run quicktest on pull requests, quicktest again on commits
_after_ they are merged into `master`, and fulltest nightly. This commit
retains quicktest on pull requests, but switches to fulltest once a
commit is merged into master. We still run fulltest nightly as well, to
detect any changes in remote APIs that we hit.
Test Plan:
Push this commit. Check that Circle CI runs its workflow normally (as
quicktest), verifying that the config parses correctly. Then, merge this
commit, and verify that the full tests have run.
wchargin-branch: ci-test-full-on-master
The referenced pull request mistakenly didn't update `config/paths.js`,
which caused build_static_site to fail in `yarn test full`.
Test plan: `yarn test full` now passes.
Currently, the cred explorer is a submodule of `app`. This is somewhat
confusing, as `app` is essentially our homepage, and the explorer is a
standalone React application which happens to get embedded in our
homepage. This commit pulls the explorer from `app/credExplorer/` into
`explorer/`, which is a better organization.
The `app/adapters` were actually only used by the cred explorer, so
those files have been moved to `explorer/adapters`. We should rename
them from "App Adapters" to "Explorer Adapters", but I didn't do that in
this commit so as to minimize the (already substantial) size of the
change.
Also, we should rename `app/` to `homepage/` in a subsequent commit.
I encountered a nasty Flow bug, which I fixed with help from @wchargin.
The result is extra annotations on the demo and fallback dynamic
adapters (so that the `static()` method is type annotated).
Test plan: This change is massive, but it's just a rename. `yarn test`
suffices.
I'm planning to pull `credExplorer` out of `app` and into its own
top-level module. This is a bit awkward, as `credExplorer` depends on
a lot of little modules that are currently collected in `app/`.
To resolve this, I pull all of these little utility modules into
`webutil/`. It's not a totally principled grouping, but it's quite
convenient and keeps these rarely changing modules out of the way.
Test plan: It's a file move, `yarn test` suffices.
The logic for converting weights into an edge evaluator should not be
coupled to the frontend application.
Progress towards #967.
Test plan: Very straightforward rename; `yarn test` suffices.
Now that the `analysis` module owns the Node and Edge types, it should
own the "fallback plugin" too. (Note that it's not actually a plugin,
though it somewhat acts like one.)
We now declare the fallback type in `analysis`, along with a fallback
analysis adapter. `app/adapters` then declares a fallback app adapter.
Test plan: `yarn test`
Progress towards #967.
There's a folder called `app/credExplorer/weights` which contains the
type specification for weights (for PageRank configurability), and also
contains frontend code for specifying those weights. This commit creates
a `weights` module under `analysis` which will contain just the logic
for specifying and using the weights, without any frontend
consideration.
It's mostly a port of the existing logic in `credExplorer/weights`, with
the caveat that app adapter related concepts have been removed, in favor
of referencing the declaration instead.
We then remove the duplicated logic and re-route imports.
Test plan: `yarn test`
* Add the demo plugin
This ports the ad-hoc demo adapter defined in
`src/app/adapters/demoAdapters.js` into its own demo plugin.
This has the benefit that the demo plugin can now be depended on outside
the app module, e.g. for the analysis module as well. Correspondingly,
I've added a demo analysis adapter.
Test plan: `yarn test`. Note that no unit tests were added, as the demo
plugin is trivial.
* Delete `src/app/adapters/demoAdapters.js`
Now that we have an explicit demo plugin at `src/plugins/demo/`, we can
remove the legacy declaration of that plugin within the `app` module.
This commit deletes the old version, and re-writes all references to
point to the standalone plugin.
Test plan: `yarn test`
Summary:
It is time. (Replaced with #622.)
Test Plan:
Running `yarn flow` suffices. Running `yarn test --full` also passes.
wchargin-branch: remove-legacy-graphql
Summary:
This test has data in the old format, and uses the `RelationalView`
method that automatically translates it. As we prepare to delete that
code, we upgrade the underlying format of this test data. The end code
is nicer to read, too (e.g., we don’t need the `connection` helper
function).
Recommend reviewing with `git show -b`.
Test Plan:
Running `yarn test` suffices.
wchargin-branch: mentionsAuthorReference-remove-legacy-graphql
Summary:
A number of modules depended on the legacy `github/graphql.js` module
solely to get at the `Reactions` enum object. As of #961, that object is
exposed from the much lighter-weight `graphqlTypes.js`. This patch
switches over the relevant imports, reducing our dependencies on this
legacy module and its large bundle size.
Test Plan:
It suffices to run `yarn flow` and verify that the two values being
imported are identical.
wchargin-branch: github-use-generated-enums
Summary:
We have a `const Reactions` convenience enum in `github/graphql.js`.
That value is useful, but that module is slated to die. This commit
extends our Flow type generation script to include these values.
Test Plan:
Existing unit tests suffice.
wchargin-branch: schema-generate-enums
For #704, we're adding plugin adapters that are specific to the needs of
the analysis module. They have a simple scope: they just provide a way
to get the declaration, and to load the corresponding graph.
Adapters for the `git` and `github` plugins have been implemented, along
with unit tests.
Test plan: `yarn test` 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.
wchargin-branch: fix-test-load-example-github
Summary:
Tests that run only on nightly builds (`yarn test --full`) and fail only
on CI (not locally) are a bit more inconvenient to debug when they fail.
This patch makes the `yarn test --full` script print all the
intermediate output in Sharness tests, which can be helpful. We don’t do
this for `yarn test` simply because it generates a ton of spam even on
successful tests.
Test Plan:
$ yarn test --full 2>&1 | wc -l
1173
wchargin-branch: test-full-verbose
Summary:
Fixes#953. See that issue for context.
Test Plan:
Unit tests updated. To see the change in action, load the SourceCred
data and expand @decentralion’s commits-authored to find commits that
were merged into non-`master` branches. Note that these commits are
rendered correctly (in the same way that they were before this patch),
and that there is no console error (new as of this patch).
wchargin-branch: git-no-warn-on-unknown-commit
Summary:
This is a quick patch for #955, pending investigation and fix.
Test Plan:
```shell
$ cd sharness/

wchargin-branch: test-skip-failing-circleci
Summary:
Fun facts:
- `new Date().getDay()` does not return the day of the month. It
returns the day of the _week_ as an integer `0 ≤ n ≤ 6`.
- `new Date().getDate()` returns the day of the month from 1 to 31.
- `new Date().getMonth()` really does return the month, but _this_ one
is zero-based!
All this to say, my implementation in #901 was a bit flawed.
Why didn’t I notice at the time? I wrote and tested the change on
2018-10-01, which was a Monday, so both `getDay()` and `getDate()` were
in fact `1`. As for me failing to notice that `getMonth()` was off by
one—well, sometimes I’m very dumb.
Test Plan:

wchargin-branch: env-fix-date-formatting
Test Plan:
Remove the SourceCred output directory, run `yarn backend`, and load
data for `sourcecred/example-github` and `sourcecred/sourcecred`. Then,
run `yarn start` and note that the cred explorer still works. Finally,
note that `yarn test --full` passes.
wchargin-branch: release-v0.2.0
Summary:
This points to #622 as the blanket issue, though really there was a long
series of pull requests worth of implementation.
Test Plan:
None.
wchargin-branch: changelog-mirror
This will enable us to test code that needs to consume the results of
running `sourcecred load`, e.g. plugin adapter code.
If you need to update the snapshot, run
(cd sharness; UPDATE_SHAPSHOT=1 ./test_load_example_github.t)
Test plan: `yarn sharness-full` passes.
Paired with @wchargin
Now that we're planning to add adapters for the `analysis` module, we
should rename the `PluginAdapter` to make it clear that it's scoped for
`app`.
Test plan: `yarn test` suffices
The plugin adapters are specific to `app/` and have logic for fetching
data from the backend, producing React nodes for descriptions, et
cetera.
However, they also have information that is generic to the plugin
itself: its name, its node/edge prefixes, and its types.
This method factors out the generic info into a `PluginDeclaration`,
which is a type (rather than an interface). Then, the plugin adapter has
a `declaration` method which returns the declaration.
Current users of the plugin adapters get additional mechanical
complexity because they need to call `.declaration().property` rather
than `.property()`, but this is not too significant.
The main benefit is that #704 is unblocked, as the cli `analyze` command
will be able to get necessary information from the declaration. As an
added benefit, the organization of plugin code is somewhat improved.
Test plan: `yarn test` sufficies, but I also ran `yarn start` and
checked the UI behavior to be safe.
The `core/attribution/` folder has some code that really is "core" in
that it deals with very basic concepts around converting graphs to
markov chains and running PageRank on them, and some code that is less
"core", like for normalizing scores and doing analysis on them.
To make progresson #704, we need an intermediary directory that has
analysis-related code that is e.g. aware of Node and Edge types, and
weights on those types, and can use them to run weight-informed
PageRank. That code shouldn't live in the app directory (since it is not
coupled to the frontend rendering), but also shouldn't live in core
(since "core" is basically finalized code with fully baked abstractions,
and per #710, this is not true of the node/edge type system).
Thus, I've decided to create the `analysis` directory. To get that
directory started, I've moved the non-core code in `core/attribution/`
to `analysis/`.
Test plan: `yarn test` passes, which is all we need, since this is a
straightforward file rename.
The `analyze` command is the first step towards #704 and #703. When
fully implemented, it will run PageRank for a loaded repository,
generating a complete graph and cred attribution.
For now, this just adds a scaffold. It does basic argument parsing, and
has help text, but the actual command is not yet implemented.
Test plan:
Unit tests verify that the analyze command is hooked into `sourcecred`
and `sourcecred help`, and that it responds to the `--help` command and
parses its arguments appropriately.
Summary:
As of this commit, `node ./bin/sourcecred.js load` uses the Mirror code,
and the legacy continuation-fetching code is not included in the
`sourcecred.js` bundle.
We do not yet perform the commit prefetching described in #923. The code
should be plenty fast for repositories that merge pull requests at least
occasionally.
Test Plan:
Running `yarn test --full` passes. Loading `sourcecred/sourcecred` works
and generates a reasonable credit attribution. Loading it again
completes immediately.
wchargin-branch: fetchGithubRepo-mirror
Summary:
This makes significant progress toward #923. As of this commit, it is
possible to use the Mirror module for the whole loading pipeline. This
process may be slow for repositories that do not use pull requests at
all (more precisely, that have large connected commit subgraphs none of
whose nodes is the merge commit of a pull request; see #920 for details)
so it is not yet the default codepath.
Test Plan:
Existing unit tests should suffice. For extra testing, I’ve added a
script that fetches a repository both via the old continuations logic
and the new Mirror logic, then constructs relational views and checks
whether the data is the same. For `example-github`, the views are
identical. For `sourcecred`, they are not: the old continuations logic
erroneously omits two commits, which the Mirror logic includes.
You can run the test like this:
```
$ node ./bin/testContinuations.js \
> sourcecred sourcecred MDEwOlJlcG9zaXRvcnkxMjAxNDU1NzA= \
> /tmp/continuations.json /tmp/mirror.json \
> 2> >(jq . >&2)
{
"child": "0d38dde23a6de831315f3643a7d2bc15e8df7678",
"parent": "cb8ba0eaa1abc1f921e7165bb19e29b40723ce65",
"type": "UNKNOWN_PARENT_OID"
}

"parent": "de7a8723963d9cd0437ef34f5942a071b850c0e7",
"type": "UNKNOWN_PARENT_OID"
}
Different. Saving to disk...
```
Use `diff -u <(jq . /tmp/continuations.json) <(jq . /tmp/mirror.json)`
to inspect the differences, and note that exactly the two missing
commits have been added and that there are no other changes. (The diff
is small: just 51 lines of nicely formatted JSON.) The full log is here:
<https://gist.github.com/wchargin/e159cac9dcf3cc3b1efbd54f59e24e0b>
I also generated the `sourcecred/sourcecred` cred attribution and viewed
it with `yarn start`, which seems to work fine.
wchargin-branch: relationalview-new-data-format
Summary:
An upcoming commit will happen to change the order in which commits are
ingested. This is not an observable change, and should not cause a
snapshot failure.
Test Plan:
Inspection.
wchargin-branch: relationalview-snapshots-order-invariant
Summary:
Generated with `flow-typed install prettier@1.13.4 --overwrite`. The
changes in #925 have been merged upstream; this pulls in the updated
signature and version.
Test Plan:
`yarn flow` passes.
wchargin-branch: flow-typed-update-prettier
Summary:
This implements the translation module described in #923. See that issue
for context.
Test Plan:
This is a mostly straightforward translation from one strongly typed
data structure to another, so Flow handles most of it.
As a check on the snapshot, run:
```
$ grep -e oid -e target -e mergeCommit \
> src/plugins/github/__snapshots__/translateContinuations.test.js.snap

```
Cross-check this against [the example-github commits][commits] thus:
- Note that commit `6bd1b4c` is the head commit, and is thus the root
commit of the `target` chain.
- Note that commits `0a22334` and `6d5b3aa`, which were merged via
pull request, appear twice each: once in the history from head, and
once as the merge commit of a pull request.
- Note that commit `0a22334` has two parents at each occurrence.
- Note that the unmerged pull request’s merge commit is `null`.

wchargin-branch: github-translate-continuations
Summary:
This fixes the following issues:
- Pull request reviews actually do not have reactions.
- We must fetch the `id` of a `Ref`.
- We must fetch the `id` of a `Commit`, `Tree`, `Blob`, or `Tag`, and
should also fetch its `oid`.
- Repository owners cannot be bots.
- Commit and reaction authors cannot be bots, organizations, or
`undefined`.
Test Plan:
Running `yarn test --full` passes, and the snapshot diff is clearly
correct.
wchargin-branch: github-fix-up-continuations
Summary:
The included schema is forked from the one in `graphql/demo.js`.
Primitive types have been added, and the `parents` connection has been
added to commit objects per #920. (We do not include this in the demo
script because without prefetching it would take a long time to load.)
Test Plan:
Unit tests added; run `yarn unit`. Then run `yarn backend` and verify
that `node ./bin/generateGithubGraphqlFlowTypes.js` generates exactly
the same output as in the types file:
```
$ node ./bin/generateGithubGraphqlFlowTypes.js |
> diff -u - ./src/plugins/github/graphqlTypes.js
$ echo $?
0
```
Change the `graphqlTypes.js` file and verify that `yarn unit` fails.
As the build config has been changed, a `yarn test --full` is warranted.
It passes.
Finally, I have manually verified that the schema is consistent with the
documentation at <https://developer.github.com/v4/object/repository/>
and related pages.
wchargin-branch: github-schema-flow-types
Summary:
Generating Flow types from a structured schema is both straightforward
and terribly useful. This commit implements it.
Test Plan:
Inspect the snapshot for correctness manually. Then, copy it into a new
file, remove backslash-escapes, and verify that it passes Flow.
A subsequent commit will generate types for the actual GitHub schema.
wchargin-branch: graphql-generate-flow-types
Summary:
Prior to this change, primitive fields were un\[i\]typed. This commit
allows adding type annotations. Such annotations do not change the
semantics at all, but we will be able to use them to generate Flow types
corresponding to a schema.
This commit also strengthens the validation on schemata to catch some
errors that would previously have gone unnoticed at schema construction
time: e.g., a node reference to a type that does not exist.
Test Plan:
Unit tests updated, retaining full coverage. The demo script continues
to work when loading `example-github` or `sourcecred`.
wchargin-branch: schema-annotated-primitives
Summary:
To ease the transition from manual continuation resolution to the Mirror
API, we update the old system to fetch commit parent OIDs, as described
in #923.

Note that the test output (as updated in this commit) includes commits
with a unique parent, a commit with no parents, and a commit with two
parents.
I also ran `node ./bin/sourcecred.js load` on sourcecred/sourcecred and
ipfs/js-ipfs. Each worked, and the resulting credit attributions loaded
fine.
wchargin-branch: github-commit-parent-oids
Summary:
This has two benefits:
- The dates on commits are data that we will probably want when we add
timestamps to authorship edges to accommodate time-weighted cred.
- Once the mirror module is integrated with the GitHub plugin, we’ll
want to fetch dates on commits, because this is the only real-world
test case for a nested field that contains a primitive field (as
opposed to a node reference), so it’ll be nice to be continually
exercising that somewhat-edge case.
Date strings are in commit-local time and do not depend on the time zone
of the requester (in contrast to [cursors]). For example, on SourceCred:
```shell
$ time node ./bin/fetchAndPrintGithubRepo.js \
> sourcecred sourcecred "${GITHUB_TOKEN}" |
> jq -rc '
> .repository.defaultBranchRef.target.history.nodes[]
> .author?.date[-6:]
> ' | sort | uniq -c
1 +03:00
6 -04:00
717 -07:00
58 -08:00
```
[cursors]: <https://github.com/sourcecred/sourcecred/pull/129#issuecomment-382970474>
Test Plan:
The snapshot contains 8 instances of `oid` and 8 instances of `date`,
which is good (each of these properties appears exactly once on each
commit, and nowhere else). Running `yarn test --full` passes.
wchargin-branch: github-commit-dates
Summary:
This commit follows up on the previous two pull requests by drawing the
rest of the owl.
Resolves#915.
Test Plan:
Unit tests included.
To verify the snapshot change, open the snapshot file, and copy
everything from `query TestUpdate {` through the matching `}`, not
including the enclosing quotes. Strip all backslashes (Jest adds them).
Post the resulting query to GitHub and verify that it completes
successfully and that the result contains a commit with an `author`.
In other words, `xsel -ob | tr -d '\\' | ghquery | jq .` with [ghquery].

The demo entry point has also been updated. For an end-to-end test, you
can run the following command to see a commit with a `null` author (with
the current state of the repository) and a commit with a non-`null`
author:
```
$ node bin/mirror.js /tmp/mirror-example.db \
> Repository MDEwOlJlcG9zaXRvcnkxMjMyNTUwMDY= \
> 3600 2>/dev/null |
> jq '(.defaultBranchRef.target, .pullRequests[0].mergeCommit) | {url, author}'
{
"url": "6bd1b4c0b7",
"author": {
"date": "2018-09-12T19:48:21-07:00",
"user": null
}
}
{
"url": "0a223346b4",
"author": {
"date": "2018-02-28T00:43:47-08:00",
"user": {
"id": "MDQ6VXNlcjE0MDAwMjM=",
"__typename": "User",
"url": "https://github.com/decentralion",
"login": "decentralion"
}
}
}
```
You can also check that it is possible to fetch the whole SourceCred
repository (ID: `MDEwOlJlcG9zaXRvcnkxMjAxNDU1NzA=`).
wchargin-branch: mirror-shallow
Summary:
See #915 for context. This adds nested field data to the “useful info”
data structure added in #857.
Test Plan:
Unit tests for `_buildSchemaInfo` updated.
