This commit #811, allowing users to set the weights of node/edge types to 0.
The WeightSlider now sets the weight to 0 when its dragged to its minimum value.
The logic for converting between weights and sliders has also been made more robust,
and is more thoroughly tested.
In cases where we wanted to set the weight to 0 (e.g. backwards Reaction edges),
the default weight has been changed.
Test plan:
Loading the UI, check that the sliders still work as expected (dragging them changes the displayed weight, dragging to the far left sets weight to 0). Check that the weights are consumed as expected (setting weight for issues to 0 leads to no cred for issues). Check that the weights for backwards reaction edges now have 0 weight. `git grep "TODO(#811)"` returns no hits.
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.

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.

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.
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.
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.
* Define Reaction edges
This adds support to `github/edges` for creating edges representing
GitHub reactions. These edges are not actually added to the graph.
Test plan: Unit tests
* Add GitHub reactions to the graph
This commit adds functional support for reactions in SourceCred.
Only thumbs-up, heart, and hooray reactions are supported for now, as
they are all unambiguously positive; adding support for negative
reactions like thumbs-down will require some more thought.
The reactions are added to the graph, and new edge types have been added
to the UI.
Test plan:
The `graphView` class has been updated to do invariant checking for the
reaction edges, including that the unsupported reaction types like
"THUMBS_DOWN" aren't added to the graph.
I've tested this feature by downloading data for a large repository
(ipfs/go-ipfs). The reaction edges appear and transfer cred reasonably.
The edge types are displayed in the weight config appropriately.
Builds on #839, #840, and #845.
Now that #832 gave us logic to parse references to commits, we have the
RelationalView find and add these references. The actual change is
a simple extension of existing reference detection logic.
Test plan: Observe that the snapshots are updated with references to
commits from the example-github repository.
Progress on #815.
Now that the GitHub plugin knows about commit messages (#828), we can
parse those commit messages to find references to other GitHub entities.
Fixed a minor typing mistake along the way.
Test plan:
Observe that a number of references have been detected among the commits
in the example GitHub repository. We mistakenly find references to
wchargin because we don't have a proper tokenizer. (#481)
Progress on #815.
In #824, we loaded every commit in the default branch's history into the
GitHub relational view, along with authorship info. This commit actually
uses that authorship info to create AUTHORS edges from the commit to the
user that authored it (whenever possible).
The implementation is quite simple: we just need to yield the commits
when we yield all the authored entities, so that we will process their
authors and add them to the graph. Also, I updated the invariant
declarations in `graphView.js`, and corrected a type signature so that the
new invariants would typecheck.
Test plan: The snapshot update shows that commits are being added to the
graph appropriately. Observe that commits which do not have a valid
GitHub user as their author do not correspond to edges in the graph.
See [example].
This is basically a solution to #815, but I'll defer closing that issue
until I've added a few more features, like reference detection.

This commit adds PluginWeightConfig, which is responsible for
adding all the weights for an individual plugin. The top-level
WeightConfig now creates multiple PluginWeightConfigs. It also takes
responsibility for hiding the FallbackPlugin.
Test plan: The PluginWeightConfig is tested (and fairly simple). The
top-level WeightConfig is not yet tested (#604), so I manually tested
that the weights in the app still function.
This commit introduces a new component, `EdgeTypeConfig`, which is
responsible for configuring the weights for a given edge type. The
config creates two `WeightSlider`s: one for the forward direction, and
one for the backward direction. The `DirectionalitySlider` is no longer
used, and is removed. This fixes#596.
So as to avoid confusion, we now describe every edge with variables, as
in 'α REFERENCES β', and clarify that the weight modifies how cred flows
from β to α. This necessitated the creation of an `EdgeWeightSlider`,
local to the `EdgeTypeConfig`, which sets up a `WeightSlider` with the
necessary greek characters.
The EdgeTypeConfig is tested, so this is continuing progress towards
solving #604.
Test plan: I manually verified that modifying edge weights has the
expected effect on cred scores. Also, some new unit tests are included.
* StateTransitionMachine.loadGraph reports success
Step one towards #586. This will enable us to chain runPagerank after
loadGraph only if the load went through successfully.
Test plan: Unit tests included.
* Add StateTransitionMachine.loadGraphAndRunPagerank
This methods combines `loadGraph` and `runPagerank` into one method
which internally chains the two method. `runPagerank` is only called if
`loadGraph` was successful.
Progress on #586.
Test plan:
The new method has attached unit tests. I implemented the unit tests via
mocking, which seemed quite convenient as the method is basically a
wrapper for chaining two other function calls.
* Combine loadGraph and runPagerank into one button
Resolves#586. The new button is called "Analyze cred".
Test plan: Unit tests, also I tested it manually.
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.

Closes#750.
Test Plan:
Comparing the raw old version with the decompressed new version shows
that they are identical:
```

> shasum -a 256 -
63853b9d3f918274aafacf5198787e18185a61b9c95faf640a1e61f5d11fa19f -

```
Additionally, `yarn test --full` passes, and `yarn start` still loads
data and runs PageRank properly.

This commit isolates all of the log-weight behavior in the weight
slider. That slider moves in log space, but the numbers printed and
passed around the WeightConfig code are now always in linear-space.
This should reduce confusion in the UI and for developers.
This commit contains two other improvements: (#588)
- Changes the (log space) range on the sliders from ±10 to ±5
- Change the order from slider, weight, name to name, slider, weight, so
that there is more visual separation between the name and the weight.
Test plan: Changes to the weight slider are tested. Changes to the
WeightConfig aren't (#604) so I manually tested the UI.
Fixes#696.
Test plan: This is basically a config change, so I manually tested it.
I ran SourceCred on gitcoinco/web, which has two bots,
and verified that the bots are correctly removed from the list of users.
Selecting "Bots" in the dropdown filter shows the two bots. Changing
the user weight does not affect the bots' scores, and changing the bot
weight does affect the bots' scores.
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.

Summary:
As a first pass toward support for analyzing whole organizations, we
allow loading multiple repositories with `sourcecred load`, combining
them into a single relational view and a single Git graph at load time.
Test Plan:
Run
```
node bin/sourcecred.js \
load \
sourcecred/example-git \
sourcecred/example-github \
sourcecred/sourcecred \
--output sourcecred/examples \
;
```
and select `sourcecred/examples` from the web view. Filter “Repository”
nodes, and note that there are three.
Note that loading a single repository without `--output` still works,
that loading a single repository with `--output` still works (respecting
the alias name), and loading not exactly one repository without
`--output` yields an appropriate error message.
Note that `yarn sharness-full` still works.

This commit changes the cred normalization algorithm so that the total
cred of all GitHub user nodes always sums to 1000. For rationale on the
change, see #705.
Fixes#705.
Note that this introduces a new way for PageRank to fail: if the
graph has no GitHub userlike nodes, then PageRank will throw an error
when it attempts to normalize. This will result in a message being
displayed to the user, and a more helpful error being printed to
console. If we need the cred explorer to display graphs that have no
userlike nodes, then we can modify the codepath so that it falls back to
normalizing based on all nodes instead of on the GitHub userlike nodes
specifically.
Test plan: There is an included unit test which verifies that the
new argument gets threaded through the state properly. But this is
mostly a config change, so it's best tested by actually inspecting
the cred explorer. I have done so, and can verify that the behavior is
as expected: the sum of users' cred now sums to 1000, and e.g. modifying
the weight on the repository node doesn't produce drastic changes to
cred scores.
Storing the user's weights in localStore enables a workflow where a
user chooses their preferred weights, and brings those weights with them
across projects and contexts. However, this is the wrong workflow:
actually, a project chooses its weights, and when a user visits a
particular project, they want to sync up with the project's choice.
Giving the user the ability to modify the weights and recalculate is
still important, so that they can propose improvements to the project
maintainer. But implicitly keeping their modified weights, and even
bringing them to other projects the user inspects, is
counter-productive.
This commit removes this dubious feature. (It's a feature we were likely
to drop anyway, as it conflicts with #703.) As an added bonus, this code
is untested, which means the feature is technical debt—so removing it
reduces our technical debt! It also removes at least one known bug.
Test plan: There are no tests. I manually verified that the frontend
still works, and that it no longer persists weights across refresh.
Summary:
This patch adds independent exponential backoff to each individual
GitHub GraphQL query. We remove the fixed `GITHUB_DELAY_MS` delay before
each query in favor of this solution, which requires no additional
configuration (thus resolving a TODO in the process).
We use the NPM module `retry` with its default settings: namely, a
maximum of 10 retries with factor-2 backoff starting at 1000ms.
Empirically, it seems very unlikely that we should require much more
than 2 retries for a query. (See Test Plan for more details.)
This is both a short-term unblocker and a good kind of thing to have in
the long term.
Test Plan:
Note that `yarn test --full` passes, including `fetchGithubRepoTest.sh`.
Consider manual testing as follows.
Add `console.info` statements in `retryGithubFetch`, then load a large
repository like TensorFlow, and observe the output:
```shell
$ node bin/sourcecred.js load --plugin github tensorflow/tensorflow 2>&1 | ts -s '%.s'
0.252566 Fetching repo...
0.258422 Trying...

```
This took just under half an hour, with 264 queries total, of which:
- 225 queries required 0 retries;
- 38 queries required exactly 1 retry;
- 1 query required exactly 2 retries; and
- 0 queries required 3 or more retries.

This commit re-introduces the git plugin, now that it has been radically
simplified as described in [1]. The new git plugin only has nodes for
commits and only has commit has-parent edges. As compared to the version
that was removed in #628, this plugin is far leaner. It doesn't bloat
the graph (for `sourcecred/sourcecred`, the git plugin data is just
164k), and as such doesn't incur much performance penalty.
Re-incorporating the git plugin also brings some tangible benefits. We
already had git nodes in the graph, as the GitHub plugin attaches them
to pull requests. Without any git plugin, these nodes are displayed as
"uknown nodes" with ugly descriptions. Also, including a git plugin,
even one that is very minimal, communicates to users that git is a
source of information to SourceCred, and that they can expect more from
it in the future.
Note that this commit breaks backcompat for existing repositories that
were locally loaded after #628. As such, it is best to
`rm -rf $SOURCECRED_DIRECTORY` and start with fresh data. Also, due to a
known bug in the WeightConfig, you should reset your browser's local
storage.
Test plan: After removing the SourceCred directory and the stale
localStorage, the cred explorer nicely displays git commits, and
connects them via has_parent edges. The NodeType filter allows filtering
to commits as expected, and the WeightConfig shows node and edge weights
for the Git plugin's nodes and edges.

It's more consistent to prepend entries to the [Unreleased] section of
the changelog, so that entries are all in reverse-chronological order.
Since we've appended the first few entries, we reverse them now.
Test plan: Not needed
The 'Score' column is renamed to 'Cred' (and its prop is renamed as
well). The column which shows how a connection or aggregation
contributes to a node's cred, as a percentage, has been rendered
nameless. It is pretty self explanatory, and the previous name
("Connection") was meaningless.
Test plan: Unit tests, also I inspected the frontend.
Some CSS magic was required.
Also creates `src/app/version.js` for storing the version string.
Test plan: Visual inspection of the footer in both Chrome and Firefox,
both on a page with very little content (the cred explorer without a
repository loaded), and on a page with more than a screen height's of
content (the homepage, or cred explorer with a large repository loaded).
In all cases, the footer unobtrusively appears in the lower-left hand
corner at the bottom of the screen, (after scrolling past all content,
if applicable).
Summary:
This commit approximately completes the implementation of #643.\* Plugin
adapters are now provided an `Assets` object at `load` time, which they
can use to resolve their plugin-specific API routes.
\* “Approximately” because there are some non-essential pieces of legacy
code that should be cleaned up.
Test Plan:
Unit tests modified, but it would be good to also manually test this.
Run `./scripts/build_static_site.sh` to build the site to, say,
`/tmp/gateway/`. Then spin up a static HTTP server serving `/tmp/` and
navigate to `/gateway/` in the browser. Note that the entire application
works.

Previously, expanding a node would display the individual connections
that contributed cred to that node. For nodes with high degree, this was
a pretty noisy UI.
Now, expanding a node displays "aggregations": for every type of
adjacent connection (where type is the union of the edge type and the
adjacent node type), we show a summary of the total cred from
connections of that type. The result is a much more managable summary
view. Naturally, these aggregations can be further expanded to see the
individual connections.
Closes#502.
Test plan: The new behavior is unit tested. You can also launch the cred
explorer and experience the UI directly. I have used the new UI a lot,
as well as demo'd it to people, and I like it quite a bit.
