This commit moves weights out of the "parameters" to TimelineCred. This
makes sense, because the Weights are now passed to TimelineCred via the
included WeightedGraph. As such, we now have the `api/load` options
include explicit Weights that are used as overrides, rather than having
them be included in the TimelineCred parameters.
Test plan: I've manually tested this commit by:
- Changing weights in the explorer, and verifying that the `recalculate
cred` button activates as expected, and the new weights are used
correctly in the resultant distribution.
- Verifying that downloading weights form the UI still works.
- Verified that uploading weights to the UI still works.
- Verifying that passing command-line weights files still works.
Also, `yarn test` passes.
This commit changes `api/load` and downstream consumers to use
WeightedGraphs instead of regular Graphs. In addition to `api/load`, we
also modify the frontends and the timeline cred calculation module.
However, we don't yet _use_ the weights from the WeightedGraph. So as to
make this commit easier to review, it only changes the data type being
passed around; however in practice the consumers ignore the weights and
simply use the underlying graph. A followon commit will modify the
consumers so that they properly retrieve weights from within the
WeightedGraph.
This is a major step towards #1557.
Test plan:
`yarn test --full` passes; manual testing verifies that the frontend
still displays cred properly, and that modifying the weights and
re-calculating shows that the weights are being used properly.
As discussed in [this GitHub comment][1], it doesn't make sense for user
node types (or user nodes) to have non-zero weight. The reason is that
we use weights for minting cred. Minting cred to users in general
doesn't make sense (having more user accounts is not intrinsically
valuable to a project) and minting cred to specific users is
inappropriate (it means that users' cred is being determined by their
power to influence the weights, rather than because of the value of
their contributions).
This commit makes two changes:
- It sets the default weight for all user types to 0. This has no
implications for cred, since the user weights were already (implicitly)
discarded because users all have null timestamps.
- It filters user node types from the weight config, so the UI no longer
incorrectly suggests that user node weights can be meaningfully changed.
As a result of the second change, the identity plugin now displays in
the weight change UI but has no node or edge types associated. As a
followon commit, we may want to add a bit of filtering logic to clean
that up.
Test plan:
Setting the default weights to 0 for the user types has no effect on
cred, as can be manually ascertained by taking an existing cred
instance, changing the user type weights, and re-calculating.
Filtering the user node types from the WeightConfig is validated through
manual inspection testing.
I've found that frontend unit testing of changes like this has limited
value; since there aren't subtle edge cases to validate, and regressions
are unlikely, I don't think we need a unit test at this time. Therefore,
I haven't added formal tests.

The upcoming DataDirectory class will use stable stringify too.
But since that will affect the snapshots, make sure those are
updated before we switch to the new load implementation.
I'm currently on a quest to separate cred computation away from any
plugin metadata (see #1557). This means we need a way to represent node
and edge weights without any explicit concept of 'types'.
This commit is a first step towards that. It removes the distinction
between 'type weights' and 'manual weights' in the weights data type.
Instead, we now just have node weights and edge weights. In contrast to
before, all weights are now interpreted as prefix matchers, e.g. a
single node or edge may match multiple weights; when this occurs, the
weights compose multiplicatively.
Since types were already identified by prefix, if a plugin wants to
assign a weight to a particular type, it may do so by specifying a
weight for that type's prefix. As before, it's possible to have a
type-level weight and a weight on a specific node, and compose them
multiplicatively.
As an added bonus, we could now sensibly have 'plugin-level' weights and
'type-level weights' and compose them multiplicatively. Thus, if we
realized that the Foo plugin is undervalued relative to the Bar plugin,
we could increase the Foo weight rather than needing to adjust all of
its types individually.
So as to keep the scope for this commit somewhat manageable, I modified
the underlying data type for Weights, but not any of the cred
computation interfaces. The weights pipeline still takes the plugin
declarations, and we still get the default type level weights from the
plugin's types. A future commit will modify the pipeline so that the
plugins provide default types alongside the Graph.
I deliberately did not provide an upgrade handler for the old style
weights JSON. This is sensible as the semantics are now different. In
the past, it was possible to specify a weight for a single node without
affecting the weights of other nodes whose addresses have the first
node's address as a prefix. Since this is no longer possible, there is
no universally "correct" way to handle the old weights files. In
practice, there are so few users that it is not a big deal either way.
Test plan:
This change has implications across the codebase and UI. In addition to
`yarn test --full` passing, I verified that:
- updating and recomputing works in the mainline UI
- updating and recomputing works in the legacy UI
- downloading weights from the UI and then explicitly loading them still
works
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.

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.
Test plan: `yarn test --full` passes.

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.
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
Thanks to @wchargin for [catching it].

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.

**Test Plan:**
`yarn test --full` is passing.
Additionally, the commands:
```sh

diff -u \
<(git show "HEAD:${filepath}" | gzip -d | 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
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.
