This modifies config.yml so that it will run full tests on a branch
called "ci-test". This will make it easier for us to test attemtps to
fix full build issues, without needing to iterate against master
directly.
As of this commit, the main SourceCred prototypes page now links to
timeline cred, meaning that timeline cred is now live. I've added a
link from the legacy explorer to the timeline explorer (which already
has a link out to the legacy explorer).
Test plan: Careful inspection of the frontend by the committer.
Also, yarn test.
This is a bulk rename of all the old explorer code into
`explorer/legacy`. Now that the timeline explorer exists, I intend to
prioritize development on that going forwards. Once the timeline
explorer is as good as the old explorer at decomposing a node's sources
of cred, I will remove the legacy explorer entirely.
Test plan: `yarn test`
This commit adds a TimelineExplorer for visualizing timeline cred data.
The centerpiece is the TimelineCredChart, a d3-based line chart showing
how the top users' cred evolved over time. It has features like tooltips,
reasonable ticks on the x axis, a legend, and filtering out line
segments that stay on the x axis.
An inspection test is included, which you can check out here:
http://localhost:8080/test/TimelineCredView/
Also, you can run it for any loaded repository at:
http://localhost:8080/timeline/$repoOwner/$repoName
This commit also includes new dependencies:
- recharts (for the charts)
- react-markdown (for rendering the Markdown descriptions)
- remove-markdown (so the legend will be clean text)
- d3-time-format for date axis generation
- d3-scale and d3-scale-chromatic for color scales
Test plan: The frontend code is mostly untested, in keeping with my
observation that the costs of testing the old explorer were really high,
and the tests brought little benefit. However, I have manually tested it
thoroughly. Also, there is an inspection test for the TimelineCredView
(see above).
It's very simple: a method that creates a copy of a `Weights`.
While writing this, I realized I should probably refactor the weights
module so that it exports a class rather than a bunch of methods
operating on a data structure. It would just be a cleaner API. But I'm
leaving that for another day.
Test plan: Unit tests added.
Now that babel is upgraded, upgrading webpack was pretty
straightforward.
- We take advantage of the new `mode` config option, and no longer need
to manually set up Uglify plugin
- Uglifyjs is back, I checked the prod build output: it's very ugly
- I updated the RemoveBuildDirectoryPlugin per instructions, and
verified it still works.
- I verified that of `yarn backend`, `yarn build`, and `yarn start` all
still work as expected.
I moved `config/babel.js` to `.babelrc.js` because it seemed like babel
7 really wanted that. I also blew away our (complicated, copied from
create-react-app) config and replaced it with a much, much simpler one.
Test plan: `yarn test` passes, `yarn start` still serves a working
server, and `scripts/build_static_site.sh` still produces a working
site.
Possibly we lost some nice features re: React debugging; if so I'll add
them back as I miss them.
We have an old version of uglify, and it's causing problems with
compiling d3-array, and also when upgrading to a newer babel.
I'm going to disable it for now, then upgrade babel, and then upgrade
webpack. Upgrading webpack will get us a later version of uglify without
these issues.
As described in #987, we use a single TTL across GitHub types. Right
now, the TTL is set to 7 days. This means that it's possible to run
`sourcecred load`, but still be missing the last 7 days worth of issues.
Now that we're doing timeline cred (cf #1212), this is not acceptable.
As a workaround until we fix#987, I'm decreasing the TTL to 12 hours.
That's still long enough to make a good experience for someone who is
tweaking config and calling `sourcecred load` a lot, but ensures that
freshly-loaded results still have recent activity.
Test plan: `yarn test`
This adds a TimelineCred class which serves several functions:
- acts as a view on timeline cred data
- (lets you get highest scoring nodes, etc)
- has an interface for computing timeline cred
- lets you serialize cred along with the graph and paramter settings
that generated it in a single object
One upshot of this design is that now if we let the user provide weights
(or other config) on load time in the CLI, those weights will get
carried over to the frontend, since they are included along with the
cred results.
TimelineCred has 'Parameters' and 'Config'. The parameters are
user-specified and may change within a given instance. The config is
essentially codebase-level configuration around what types are used for
scoring, etc; I don't expect users to be changing this. To keep the
analysis module decoupled from the plugins module, I put a default
config in `src/plugins/defaultCredConfig`; I expect all users of
TimelineCred to use this config. (At least for a while!)
Test plan: I've added some tests to `TimelineCred`. Run `yarn test`. I
also have a yet-unmerged branch that builds a functioning cred display
UI using the `TimelineCred` class.
fixup tlc
This adds the `filterTimelineCred` module, which dramatically reduces
the size of timeline cred by throwing away all nodes that are not a user
or repository. It also supports serialization / deserialization.
Test plan: unit tests included
This module takes the timeline distributions created by
`timelinePagerank`, and re-normalizes the scores into cred. For details
on the algorithm, read comments and docstrings in the module.
Test plan: Unit tests added.
As the name would suggest, this module allows computing timeline
PageRank on a graph. See documentation in the module for details on the
algorithm.
Test plan: The module has incomplete testing. The timelinePagerank
function calls out to iterators for getting the time-decayed node
weights and the time-decayed markov chain; these iterators are tested.
However, the wrapper logic that composes these pieces together,
calculates seed vectors, and runs PageRank is not tested. I felt it
would be a pain to test and settled for reviewing the code carefully,
and putting a cautionary note at the top of the function.
This commit adds new weight evaluators for nodes and edges. Unlike the
previous evaluator, edges and nodes are handled as separate concerns,
rather than composing the node weights into the edge weights. I think
this separation is cleaner.
Both evaluators use only the address, not the full (Node or Edge)
object. Although we may want to give the edge evaluator access to the
full Edge later, if we decide we want node-type-differentiated edge
weights (e.g. if a hasParent edge has a different weight depending on
whether it is connected to an Issue or a Repository).
weightsToEdgeEvaluator has been refactored to use the new evaluators,
and has been given a deprecation notice.
Test plan: `yarn test`
This commit adds an `interval` module which defines intervals (time
ranges), and methods for slicing up a graph into its consistuent time
intervals. This is pre-requisite work for #862.
I've added a dep on d3-array.
Test plan: Unit tests added; run `yarn test`
#1167 added some info to the README about how the user needs to have ssh keys setup. This was true at the time, but changed as a result of #1210. This commit fixes that up by removing the now-outdated information.
* Quicker failure and description when invalid token supplied
Fixes#1156
When users export a GitHub API token that has insufficient privleges
or has been revoked, we have been using a catch all error with retry
to handle it. This change adds a new error type for bad credentials
and does not retry.
Test plan:
There are no unit tests that cover this, however, you can test the
change by supplying a revoked token and attempting to load a GitHub
repo.
* Minor: reunite comment with relevant code block
* Update Changelog: Fail quicker and with information when using invalid GH token (#1161)
* Documentation updates
Added note on Changelog update format, SSH key requirements, and formatted the console (CLI) blocks a little better.
* Minor formatting fixes
* Revert a line wrap commit as it is not appropriate on README.md
* Removed prompt tokens and changed non-visible formatting
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.
The dependabot bot has an inconsistent typename in GitHub's database.
We'll blacklist it so we can continue loading `sourcecred/sourcecred`.
Test plan: `node bin/sourcecred.js load sourcecred/sourcecred` fails
before this commit, and succeeds after.
This commit resolves an inconsistency where we called edge weights
`toWeight` and `froWeight` in the core/attribution module, but
`forwards` and `backwards` in the analysis module.
I changed field names in the PagerankGraph JSON, so I bumped its compat.
Test plan: `yarn test --full` passes.
This commit changes CI to test against node 12 and 10 instead of node 8.
I test against node 12 by default (it will be LTS soon, and it has a
number of nice improvements compared to 10). We test node10 on the
nightly and post-merge, that way we will still discover quickly if we
have a problem with node 10, but it won't slow down CI for merges.
I'm just dropping explicit support for node 8 entirely, since node 8 is
end-of-life soon (Dec 19).
Test plan: I've locally verified that `yarn test --full` passes for both
node 10 and node 12.
This commit just adds a test which verifies that when an
OrderedSparseMarkovChain is created by graphToMarkovChain, its nodeOrder
is the graph's canonical node order.
Test plan: `yarn test`
This means that we no longer need to expose methods for extracting the
order from serialized JSON. We can always count on iterating over the
nodes and edges in sorted order.
Test plan: `yarn test`; tests updated.
I've regenerated the yarn.lock file (by removing it and then re-running
yarn). This picks up [a fix I authored][fix] for node-eval, which was
preventing `yarn test --full` from passing in node 10 and 12. With this
upgrde of transitive dependencies, we're now ready to officially support
newer versions of node.
Test plan: `yarn test` passes.
Since upgrading to flow 0.102.0, we've been having CI issues where flow
fails as "out of retries". In my testing, downgrading flow seems to
resolve this, although it's hard to be certain as the issue strikes
sporadically.
Test plan: This commit definitely works locally; hopefully it will
consistently pass in CI as well.
This commit enables Greenkeeper, along with an initial upgrade push for our dependencies.
I've reverted a number of upgrades, and also added them to the
greenkeeper ignore list. They mostly relate to babel/webpack stuff,
which I'm reluctant to dive into now (there have been major upgrades for
both babel and webpack) but we should address eventually. There are also
a few oddballs like whatwg-fetch and history.
Test plan: `yarn test --full` passes.
This commit updates eslint from v4 to v6. In doing so, I've moved off of
the create-react-app base eslint config. We were on an old version (v2)
and it doesn't make sense to update to v4, as in v4 create-react-app
uses typescript. Also, it didn't make sense to stay on
create-react-app's v2 config, because then it had unmet peer dependency
constraints on old versions of eslint.
Instead, I've moved us to use the default rules for eslint,
eslint-plugin-react, and eslint-plugin-flowtype.
I also made some changes to the codebase to satisfy the new lint rules
that came with this change.
Test plan: `yarn test` passes.
This commit deletes and regenerates the `yarn.lock` file, with the
effect that all dependencies are upaded to the latest version allowed by
our package.json. (For example, if we are pinned to `^2.4.0`, we might
now get `2.6.3`.)
This commit was generated via:
```Bash
$ rm yarn.lock
$ yarn
```
Test plan: `yarn test --full` passes, and I also manually tested the
frontend.
This necessitated a number of type fixes:
- Upgraded the express flow-typed file to latest
- Added manual flow error suppression to where the express flow-typed
file is still using a deprecated utility type
- Removed type polymorphism support on map.merge (see context here[1]).
We weren't using the polymorphism anywhere so I figured it was simplest
to just remove it.
- Improve typing around jest mocks throughout the codebase.
Test plan: `yarn test --full` passes.

This commit updates our prettier version from `1.13` to `1.18`. Looks
like software does get better over time! I like all of the changes.
Test plan: `yarn test` passes. I've manually inspected the diffs.
When we took a dep on better-sqlite3 in #836, we used a fork, because
better-sqlite3 did not yet support private in-memory databases via the
`:memory:` filepath. As of better-sqlite3 v5, this has been added to
mainline, so we no longer need the fork.
The v4->v5 transition involves some breaking changes. The only ones that
affected us were two field renames, from `lastUpdateROWID` to
`lastUpdateRowid`, and `returnsData` to `reader`.
Test plan:
After updating the field accesses, `yarn test --full` passes. For added
safety, I also blew away cache, loaded a nontrivial repository, and
verified that the full cred workflow still works.

Summary:
General cleanup to `update_snapshots.sh`, primarily such that it is free
of race conditions and does not clobber your build output directory. The
mechanism is the same as used in `yarn test`, via `SOURCECRED_BIN`.
Test Plan:
Remove your build directories (`rm -r ./bin ./build`), then run this
script (`./scripts/update_snapshots.sh`) and check that each subprocess
is properly invoked and all tests pass. Check that the temporary build
directory is cleaned up.
wchargin-branch: update-snapshots-cleanup
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.
The GitHub plugin no longer adds a Node to the graph for Git commits.
Instead, it creates a dangling edge to it. This frees the GitHub plugin
from responsibility for setting the timestamp or other metadata for Git
nodes.
The Git plugin no longer adds a Commit Node to the graph immediately when
encountering a commit's parent hash. Instead, it creates an edge to the
parent, and then fills in the parent node once it is encountered in the
commit store.
Test plan: Load a real repository with merged pull requests
(e.g. sourcecred/research) into the explorer, and verify that GitHub
commit entities are still connected to Git commits, and that Git
commits are still connected to their parents.
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 commit modifies the base `Graph` class so that nodes are now
represented by `Node` objects rather than `NodeAddressT`. The intention
is to start adding additional fields (e.g. description and timestamp) to
nodes, although that is not included in this commit.
See #1136 for rationale.
Test plan: The graph is very well tested, and this commit adds
additional tests and invariant checking. Some additional test code
needed update. `yarn test --full` passes, and the SourceCred UI works as
expected.
PagerankGraph's `node` and `edge` getters returned null for unavailable
entries, rather than undefined. This is inconsistent with general JS
behavior, and with the base Graph. I've now cleaned it up.
Test plan: unit tests updated; `yarn test` passes.
Every GitHub entity now has a `description` method which returns a short
markdown description. These will be added to the graph as part of #1136.
Test plan: Inspected snapshots, `yarn test --full`.
