Investment Quality

Beta

Reclassifies engineering effort based on bug attribution. Commits that introduced bugs are retrospectively counted as poor investments.

How it works

Methodology

Investment Quality reclassifies engineering effort based on bug attribution data. Commits identified as buggy origins (those that introduced bugs later fixed by someone) have their grow and maintenance time moved into the Wasted Time category. Their waste (fix commits) remains counted as productive. All other commits retain their standard classification: grow is productive, maintenance is maintenance, and waste (fixes) is productive.

Relationship to Growth / Maintenance / Fixes

The standard model classifies commits as Growth, Maintenance, or Fixes. Investment Quality adds a quality lens: a commit that introduced a bug is retrospectively counted as a poor investment — the engineering time spent on it was wasted because it ultimately required additional fix work. Fix commits (Fixes in the standard model) are reframed as productive, because fixing bugs is valuable work.

Proposed API Endpoint

Currently computed client-side from commit and bug attribution data. Ideal server-side endpoint:

POST /v1/organizations/{orgId}/investment-quality
Content-Type: application/json

Request:
{
  "startTime": "2025-01-01T00:00:00Z",
  "endTime": "2025-12-31T23:59:59Z",
  "bucketSize": "BUCKET_SIZE_MONTH",
  "groupBy": ["repository_id" | "deliverer_email"]
}

Response:
{
  "productivePct": 74,
  "maintenancePct": 18,
  "wastedPct": 8,
  "buckets": [
    {
      "bucketStart": "2025-01-01T00:00:00Z",

b4828aeThis commit introduces a **new capability** to **Workerd's JavaScript API** by adding a `ctx.cache` object with a `purge` method, enabling **cache-enabled workers** to programmatically clear their caches. It establishes the necessary **API infrastructure** within the `ExecutionContext` and `Worker::Api` interface, including new types like `CachePurgeError` and `CachePurgeResult`. While the default implementation is a stub, returning `kj::none` for `ctx.cache` when not explicitly overridden, this **API extension** provides the foundation for embedding applications to supply concrete cache purging functionality. The change also updates **TypeScript type definitions** for `experimental` and `latest` snapshots to expose this new `CacheContext` and its associated purge methods.Mar 308grow
9df0276This commit introduces a **new capability** by extending the **`ThreadContext::HeaderIdBundle`** within the `workerd/io` module. It adds an `origin` member of type `kj::HttpHeaderId` to the `HeaderIdBundle` struct and initializes it, enabling the system to explicitly track and manage the **`Origin` HTTP header** internally. This enhancement prepares the `ThreadContext` for more robust handling of origin-related logic, potentially for security, CORS, or other HTTP request processing within `workerd`. The change is primarily for **internal use**, improving the framework's ability to access and utilize this critical header.Mar 112grow
4b7b4e5This commit introduces a **new capability** to facilitate **HTTP header identification and retrieval** across the C++ and Rust FFI boundary within the **`kj` library**. It defines `HttpHeaderId` as an opaque type, enabling C++ code to pass these identifiers to Rust and receive corresponding header values back. Specifically, the FFI layer now includes a C++ function `get_header_by_id` that leverages Rust's `get_by_id` implementation for `HttpHeadersRef` to fetch header values. This establishes a robust **C++ to Rust to C++ pass-through mechanism** for `HttpHeaderId`, significantly enhancing interoperability for HTTP header management. Comprehensive tests have been added in both C++ and Rust to validate this round-trip functionality.Mar 54grow
