Breakdown of growth, maintenance, and fixes effort over time.
Bugs introduced vs. fixed over time.
No bugs introduced or fixed in this period.
Reclassifies engineering effort based on bug attribution. Commits that introduced bugs are retrospectively counted as poor investments.
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.
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.

| b9f452b9 | This commit **adds comprehensive unit tests** for the recently introduced `lastActivityTime` tracking and `terminateInteraction` API within the **Thrift C++2 library's interaction management**. The tests verify correct interaction snapshot information, `lastActivityTime` progression, and successful interaction termination. Additionally, it **enhances the `thriftdbg` utility** by wiring up `lastActivityTime` to its `dump` request output, allowing developers and operators to inspect `idleDurationMs` and `lastActivityTimeIso` for active interactions. This work improves the **test coverage and debuggability** of Thrift interactions, providing better insights into their lifecycle and state. | Mar 10 | 1 | maint |
| 486a5176 | This commit introduces **new capabilities** for **Thrift C++2 interaction management** by tracking the `lastActivityTime_` for each `Tile` interaction, exposed via `getLastActivityTime()` and included in `InteractionInfo` snapshots. It also adds a virtual `terminateInteraction(int64_t id)` method to `ManagedConnectionIf`, with a thread-safe implementation in `RocketServerConnection` that schedules termination onto the connection's event base. These enhancements allow external systems, such as idle-reapers or quota enforcers, to **detect and terminate specific long-idle interactions** without needing custom bookkeeping or dropping entire connections. This provides more granular control over **Thrift transport layer** resources and improves service resilience. | Mar 6 | 5 | grow |
| a9d36035 | This commit introduces a **new capability** to the **Thrift C++2 server's request queuing mechanism**, specifically within the `RoundRobinRequestPile`, by exposing `PreEnqueueFilter` and `DequeueObserver` interfaces. These new hooks allow users to implement **custom request filtering and observation logic**, such as external byte tracking, directly on `ServerRequest&` objects without modifying core Thrift code. The `PreEnqueueFilter` enables custom rejection logic before enqueuing, and the `DequeueObserver` is now comprehensively called for both successfully dequeued and discarded/expired requests, providing full lifecycle visibility. This **feature enhancement** significantly improves the extensibility and control over how requests are managed and monitored within the `RoundRobinRequestPile` component. |

| 3ed5c76e | This commit introduces a **new capability** to the **`RoundRobinRequestPile`** by allowing **per-priority, per-bucket queue size limits**. Previously, only a single global limit was available, but now users can configure distinct maximum request counts for each priority level via `numMaxRequestsPerPriority` in `RoundRobinRequestPile::Options`. This enhancement provides more granular control over **resource management** and **quality of service** within Thrift servers, ensuring critical requests can have larger queue capacities than less urgent ones. The implementation includes updates to the `enqueue` logic and correct handling for `addInternalPriorities` in Thrift interactions, alongside new test cases to verify functionality. | Feb 22 | 3 | grow |
| 1e11c25a | This commit **updates and refines existing comments** across various parts of the codebase. The changes are primarily focused on improving **code readability and clarity**, ensuring that the inline documentation accurately reflects the current implementation or provides better context. This is a **maintenance** task aimed at enhancing the developer experience by making the code easier to understand and navigate, with no functional impact on the software's behavior. | Feb 14 | 2 | – |
| f8124fe0 | This commit **removes the `thrift_enable_streaming_tracking` feature flags** from the **Thrift streaming infrastructure**, specifically impacting `HandlerCallbackBase` and `ArtilleryStreamHandler`. As the underlying streaming tracking functionality, which preserves and passes `ContextStack` for event handler callbacks, has been fully rolled out, these flags are now obsolete. This **maintenance and cleanup task** simplifies the codebase by removing conditional logic, making **streaming tracking unconditionally enabled** across all Thrift services. It also cleans up associated test cases that validated disabled behavior and updates BUCK dependencies by removing the `//thrift/lib/cpp2:flags` dependency from `streaming_trace`. | Feb 12 | 2 | – |
| 2b9f655a | This commit introduces **streaming metrics support** for the **Rust Thrift Server**, aligning its capabilities with existing C++ Thrift servers. It adds a new `set_stream_context_stack()` method to the `ReplyState` trait in `thrift/lib/rust/src/processor.rs` and updates the Rust Thrift code generator templates (`thrift/compiler/generate/templates/rust/lib/server.mustache`) to transfer `ContextStack` ownership from Rust to C++ during streaming RPCs. This **new capability** enables `StreamMetricEventHandler` callbacks in the C++ `ServerStreamFactory`, allowing for crucial **observability** of streaming services, including tracking `active_streams` and per-method dynamic timeseries counters, as verified by new integration tests. | Feb 10 | 8 | grow |
| 6de4360f | This commit provides a **documentation update** for the **Thrift C++2 server** by adding a comprehensive comment to `thrift/lib/cpp2/server/TokenBucketConcurrencyController.h`. The new comment clarifies the **experimental nature** and **purpose** of the `TokenBucketConcurrencyController`, which is designed for managing server concurrency. It also details the specific activation flag required to enable this feature, thereby improving developer understanding and usage guidance for this **concurrency control mechanism**. | Feb 10 | 1 | maint |
| 87b1b9e9 | This commit introduces a **new debugging capability** by enhancing the `thriftdbg dumpRequests` output to include detailed **interaction (tile) snapshot information**. It modifies the **Thrift server connection context** and **RocketServerConnection** to expose active interaction details such as ID, reference count, age in milliseconds, and wall-clock creation time. This **observability improvement** allows developers to easily identify and debug long-hanging or problematic interactions on server connections with minimal runtime overhead. The changes involve adding an `InteractionInfo` struct, new methods like `getInteractionSnapshots` and `forEachTile`, and updating `getServerSnapshot` to collect this crucial diagnostic data. | Feb 4 | 8 | grow |
| dd4ef6d7 | This commit performs a **cleanup and refactoring** by **removing the `StreamMetricCallback` interface** and its associated **stream metrics infrastructure** from **Thrift OSS**. Specifically, the `thrift/lib/cpp2/server/metrics/StreamMetricCallback.h` header is deleted, along with its BUCK build targets and dependencies. The `StreamCallbackManager.h` file within the **Rocket transport server details** is updated to remove all references to the deprecated interface, including functions like `getNoopStreamMetricCallback` and `createStreamClientCallback`. This change completes the removal of the stream metrics system, simplifying the codebase and eliminating unused components. | Jan 27 | 2 | maint |
| 52eb5332 | This commit performs a **cleanup refactoring** within the **Thrift Rocket transport layer**, specifically removing the now-unused `StreamMetricCallback` infrastructure. This involves eliminating constructor parameters, member variables, and method calls related to `StreamMetricCallback` from core components like `RocketServerConnection`, `RocketStreamClientCallback`, `RocketRoutingHandler`, and `ThriftServer`. The change simplifies the codebase by removing dead code, as all stream metrics have been migrated to `StreamMetricEventHandler` in a prior phase. This significantly improves the maintainability and reduces the complexity of the **Rocket server and client connection management**. | Jan 24 | 14 | maint |
| 9e696061 | This commit **fixes** a critical error classification in the **Thrift HTTP2 layer**, specifically within `SingleRpcChannel`. Previously, HTTP 429 (Too Many Requests) responses were incorrectly treated as generic `RECV_UNKNOWN` transport errors, leading to inappropriate client behavior. Now, the system correctly maps HTTP 429 responses to `kAppOverloadedErrorCode`, which the **ServiceRouter** translates into an `APP_OVERLOAD` error. This **enhancement** ensures that 429 responses are properly recognized as retriable throttling signals, aligning their handling with existing HTTP 503 `Retry-After` logic and improving client resilience by enabling `RETRY_ON_HOST_OVERLOADED`. | Dec 22 | 2 | waste |
| d0153c3b | This commit **enhances diagnostics** for `CREDIT_TIMEOUT` errors within **Thrift's Rocket transport** by introducing a `chunksInMemory` counter in `RocketStreamClientCallback`. This counter tracks the number of stream chunks that have been received but are still pending transmission, incrementing on `onStreamNext` and decrementing upon successful message delivery. The `CREDIT_TIMEOUT` error message now includes this `chunksInMemory` value, providing crucial context to determine the root cause of the timeout. This **diagnostic improvement** helps distinguish whether the issue is due to **slow transport/egress buffer congestion** (high `chunksInMemory`) or a **slow client not sending credits** (low `chunksInMemory`), thereby streamlining debugging efforts for stream timeouts. | Dec 17 | 2 | grow |
| 97e66483 | This commit **refactors** the **Thrift C++2 asynchronous server infrastructure** to enhance event tracking for Bi-directional (BiDi) RPCs. It updates `ServerBiDiSinkBridge`, `ServerBiDiStreamBridge`, `ServerBiDiStreamFactory`, and `ServerCallbackStapler` to utilize **BiDi-specific event hooks** rather than generic stream/sink event notifications. This change provides **enhanced visibility into the BiDi RPC lifecycle**, enabling more precise tracking of operation states, errors, and cancellations. For instance, `ServerCallbackStapler` now reports the final BiDi operation state in its destructor, improving overall observability and debugging capabilities for BiDi RPCs. | Nov 19 | 4 | maint |
| 2d388389 | This commit introduces **new capabilities** to the `ContextStack` by integrating **BiDi event handling**. It adds methods like `onBiDiSubscribe`, `onBiDiSinkNext`, and `onBiDiStreamNext` to `thrift/lib/cpp/ContextStack.h` and implements them in `thrift/lib/cpp/ContextStack.cpp`. This allows the `ContextStack` to dispatch all **BiDi lifecycle events**—including subscription, sink/stream operations, and completion—to registered `BiDiEventHandler` instances. The change enables comprehensive monitoring and interaction with **BiDirectional streaming RPCs** within the Thrift C++ runtime. | Nov 19 | 2 | grow |
| a0a79193 | This commit introduces a **new capability** by adding `BiDiEventHandler`, a dedicated event handler for **bidirectional streaming RPCs** within the **Thrift C++ runtime**. Defined in `thrift/lib/cpp/BiDiEventHandler.h`, this new class provides virtual methods such as `onBiDiSubscribe` and `handleBiDiStreamError` to manage the full lifecycle of BiDi RPC events. The existing **Thrift event handling infrastructure** is updated, with `TProcessorEventHandler` now integrating and managing this new handler via methods like `getBiDiEventHandler`. This change significantly improves **separation of concerns** by isolating BiDi-specific event logic from general stream/sink handlers, providing a more robust and organized foundation for complex bidirectional communication patterns. | Nov 19 | 2 | grow |
| be97484c | This commit introduces a **new capability** by integrating `ContextStack` into the **Thrift BiDi bridges**, specifically `ServerBiDiSinkBridge` and `ServerBiDiStreamBridge` within the `thrift/lib/cpp2/async` module. This integration enables **event notifications** for various sink and stream operations, such as subscription, item processing, and flow control. The `ServerBiDiStreamFactory` is updated to correctly pass the `ContextStack` during bridge construction. This foundational change lays the groundwork for enhanced **observability and metrics collection** within Thrift BiDi services. | Nov 11 | 3 | grow |
| 2a282d9c | This commit performs a **maintenance** task by **removing an overly verbose log statement** that was generating excessive output. The change improves the clarity and signal-to-noise ratio of the **system's logging output**, making it easier for developers and operators to identify critical information. This action helps **reduce log spam** and may offer minor **performance improvements** by decreasing I/O operations related to logging. | Nov 6 | 2 | – |
| dc7df5ac | This commit introduces a **new feature** to enhance the **quota enforcement and reporting mechanism** within the RPC transport layer. It updates the system to incorporate the **service name** into the quota hierarchy, allowing for more granular `servicename:clientId` reporting. Specifically, the `thrift/lib/cpp2/transport/core/RpcMetadataUtil.cpp` module is modified to **inject quota configuration** from request headers into the RPC metadata via `makeRequestRpcMetadata`. This ensures that server-side components receive and apply the correct quota reporting options when enabled in `SRConfig`, leading to more flexible and precise quota management. | Oct 16 | 1 | grow |
| 0c4a4835 | This commit **enhances quota enforcement** by updating the route handler to support a new quota hierarchy that includes the service name, forming `servicename:clientId`. It **modifies the RPC metadata utility** in `thrift/lib/cpp2/transport/core/RpcMetadataUtil.cpp` to conditionally inject the quota configuration into the server request. This **new capability** ensures that if a customer has enabled quota reporting in their `SRConfig`, the relevant configuration is passed downstream, providing more granular control over resource usage. | Oct 14 | 1 | grow |
