Walkthrough

This pull request converts the SDK to an async-first, builder-based API by introducing ABsmartly and ABsmartlyBuilder for fluent configuration, replacing SDK::new with builder/new entry points, and redesigning context creation to fetch ContextData remotely with retry logic via backoff_ms. Extends Context with lifecycle methods (become_ready, become_failed, ready_error), state fields (failed_error, publish_delay, refresh_period), data fetcher integration for dynamic refresh, and publisher notification via ContextPublisher trait with DefaultContextPublisher. JSON expression operators are refactored: containment logic moves from in_op to contains_op with reversed (haystack-first) operand order; match_op gains RegexBuilder with explicit limits and error logging; comparison operators adopt is_some_and pattern; evaluator dispatch is updated to route both "in" and "contains" keys to contains_op. AudienceMatcher adds diagnostic logging for parse errors and filter validation. Test suites across assigner, murmur3, and md5 are refactored to use parameterised macros for expanded coverage. Cargo.toml adds tokio "time" feature and new dependencies (urlencoding, log). README is extensively rewritten with async examples and builder documentation. GitHub Actions workflows update Rust toolchain installation action.

ContextOptions (publish_delay, refresh_period, event_logger) was
silently unused. Now properly applied when creating contexts.
Replace eprintln! calls with log::warn!/error! for proper library use.

- Add close() as alias for finalize()
- Add is_closed() as alias for is_finalized()
- Add is_closing() as alias for is_finalizing()
- Standardize "ABsmartly Context is finalizing." to "ABsmartly Context is finalized."

…fresh()

Nine tests were calling the internal refresh_with(data) method directly,
bypassing the data fetcher layer. Updated all refresh tests to use
set_data_fetcher() with a mock closure and call the public refresh() API.

Do not clear the queue before publish has actually succeeded.

pending, exposures, and goals are reset before the publisher runs. With DefaultContextPublisher, the PUT is spawned fire-and-forget and its result is ignored, so a network failure—or no Tokio runtime at all—silently loses those events.

Inline comments:
In `@Cargo.toml`:
- Line 24: The Tokio dependency in Cargo.toml is missing the "time" feature used
by src/sdk.rs (calls to tokio::time::sleep at ~lines 229 and 240); update the
tokio dependency entry to include "time" in the features array so the time
module is compiled (i.e., change the tokio = { version = "1.0", features =
["rt-multi-thread"] } entry to include "time"). Ensure the features list
contains both "rt-multi-thread" and "time" so tokio::time::sleep in src/sdk.rs
works for downstream builds.

In `@README.md`:
- Around line 125-133: The README example uses context.refresh(fresh_data) but
Context::refresh() is the no-arg method; replace the call with
context.refresh_with(fresh_data) and mention the correct by-value API
(refresh_with) when showing ContextData deserialization so the example compiles;
update the snippet to call refresh_with on the Context instance instead of
refresh.

In `@src/context.rs`:
- Around line 74-99: The constructors and state transition methods (new,
new_with_options, become_ready and any other code paths that set self.state =
ContextState::Error) update state but never emit lifecycle events; call the
existing log_event method after changing state to notify listeners: after
setting self.state = ContextState::Ready in new, new_with_options and
become_ready invoke self.log_event("ready", ...) with appropriate payload, and
likewise ensure any place that assigns self.state = ContextState::Error calls
self.log_event("error", ...) with the error details so event_logger receives the
lifecycle events.

In `@src/jsonexpr/operators/mod.rs`:
- Around line 92-101: Add a regression test that exercises the invalid-regex
branch in match_op: call the match_op (or the public operator function that
invokes RegexBuilder) with a text value and a deliberately invalid pattern like
"(", and assert the returned Value is Value::Null; put the test alongside the
other operator tests (create a new #[test] that constructs the operand Values,
calls match_op, and asserts equality with Value::Null) so the behavior of the
RegexBuilder Err path is locked in.

In `@src/models.rs`:
- Around line 161-166: ContextOptions is non-Clone because event_logger is
Box<dyn Fn...>, which forces callers to rebuild options; change the event_logger
field to Option<Arc<dyn Fn(&crate::context::Context, &str,
Option<serde_json::Value>) + Send + Sync + 'static>> and derive/implement Clone
for ContextOptions so instances can be cheaply shared; update uses/imports to
include std::sync::Arc and adjust any construction sites to wrap callbacks with
Arc::new(...) rather than Box::new(...).

In `@src/sdk.rs`:
- Around line 298-311: The refresh fetcher closure installed via
context.set_data_fetcher contains a blocking rt.block_on on
tokio::runtime::Handle::try_current() which will panic when invoked from async
contexts; change the implementation to use tokio::task::block_in_place to create
a blocking section and call Handle::current().block_on(...) inside it so the
fetcher can be invoked from async tasks safely. Specifically, update the closure
passed to context.set_data_fetcher (the refresh fetcher used by
Context::refresh) to wrap the inner block_on call in tokio::task::block_in_place
and switch from try_current() to Handle::current(), preserving the existing
error mapping (e.g., map_err messages) for both the HTTP request
(client.get...send) and JSON parse (resp.json::<ContextData>()) so behavior and
errors remain the same.
- Around line 88-90: The builder's agent(...) value (config.agent) is never
applied to outgoing HTTP requests; update each request construction path that
currently sets "X-API-Key" and "Content-Type" (the request-building code used in
the methods that set those headers) to also set the User-Agent header when
config.agent.is_some(): read config.agent, and if present call the request
builder's header method to add "User-Agent" (or header::USER_AGENT) with the
stored string; keep the existing timeout logic and ensure agent() remains as the
setter for config.agent so the header uses the same stored value.

### Refreshing the Context with Fresh Experiment Data

You can add additional units to a context by calling the `set_unit()` method. This method may be used, for example, when a user logs in to your application, and you want to use the new unit type in the context.

**Note:** You cannot override an already set unit type as that would be a change of identity. In this case, you must create a new context instead.
For long-running contexts, the context can be refreshed manually with updated experiment data:

```rust
context.set_unit("db_user_id", "1000013").unwrap();
let fresh_data: ContextData = serde_json::from_str(&api_response)?;

context.refresh(fresh_data);
```

Use refresh_with in the example.

Context::refresh() takes no arguments and pulls via the configured fetcher; the by-value API is refresh_with(fresh_data). As written, this snippet does not compile.

⚠️ Potential issue | 🟡 Minor

The event logger never sees the documented ready/error lifecycle events.

These state transitions update the context, but none of them call log_event("ready", ...) or log_event("error", ...). Consumers wiring event_logger will therefore never observe the two lifecycle events now advertised by the public API.

refresh() can still panic outside a multi-thread Tokio runtime.

Lines 302-303 assume both block_in_place support and a current runtime handle. A Context created via create_context_with() can be refreshed from plain synchronous code, and a current-thread runtime will panic here as well. Please either make refresh async end-to-end, or fall back to a private runtime when no suitable Tokio runtime is active.

⚠️ Potential issue | 🟠 Major

set_override(s) bypass the finalisation guard.

These methods are now fallible, but Lines 318-331 never check is_finalized() or is_finalizing(). That lets callers change treatment resolution after finalize(), unlike the other mutating APIs on Context.

 pub fn set_override(&mut self, experiment_name: &str, variant: i32) -> Result<(), String> {
+    if self.is_finalized() {

⚠️ Potential issue | 🟠 Major

Fail fast when a supplied unit is invalid.

Context::set_unit() already rejects blank/conflicting values, but Line 282 only logs the failure and still returns a ready context. That means create_context() can succeed with a partially initialised context and silently change assignment behaviour. Please propagate the error on the Result-returning path instead of returning Ok(...).

In `@src/sdk.rs` around lines 281 - 285, The loop that calls Context::set_unit for
each (unit_type, uid) currently only logs errors and continues, so
create_context can return a partially-initialized Context; change the loop to
propagate failures by returning the error on the Result path instead of just
warn!-ing: when context.set_unit(&unit_type, &uid) yields Err(e) in the loop,
return Err(e) (or map/convert e into the function's error type) so
create_context (or the surrounding function) fails fast; ensure you update any
function signature/err conversions as needed and keep references to
Context::set_unit, units, and create_context consistent.

Align the IN operator with the collector and the other ABsmartly SDKs by
using haystack-first operand order ([haystack, needle]) — IN is a CONTAINS
check. Register a 'contains' operator key as an alias for the same
implementation, keeping 'in' for backwards compatibility with existing
audiences. Tests updated to the haystack-first convention.

103-106: ⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Avoid logging the evaluated regex pattern.

pattern_str can be produced from a variable operand, so an invalid pattern may leak user/customer data into logs. Keep the compiler error, but omit or truncate the pattern value.

Proposed fix
-                Err(e) => {
-                    error!("Invalid regex pattern '{}': {}", pattern_str, e);
+                Err(e) => {
+                    error!("Invalid regex pattern: {}", e);
                     Value::Null

- Replace the nonexistent dtolnay/rust-action@stable with
  dtolnay/rust-toolchain@master (the action reference CI failed to resolve).
- Resolve clippy warnings (map_or simplifications, manual bit-rotation,
  derivable Default, iterating map keys, single-iteration loop) and extract a
  complex closure type into an EventLogger type alias.
- Apply rustfmt.

All 318 tests pass; clippy (-D warnings), fmt --check, and cargo doc are clean.

Pin dtolnay/rust-toolchain to specific version or commit SHA across all workflow jobs. All five action references use @master, which is a moving target that can introduce breaking changes or security vulnerabilities without notice. Pin to an immutable reference for stability and supply-chain security.

  • .github/workflows/ci.yml#L26-L26: pin the action reference in the test job to a specific version tag (e.g., @1.0.0) or commit SHA.

The matrix tested Rust 1.70.0, but the dependency tree and the v4 Cargo.lock
require a newer toolchain (1.70 fails with "failed to parse lock file"). There
is no declared MSRV and 1.70 never actually built. Test on stable across
ubuntu/macos/windows; a real MSRV can be pinned later via rust-version if needed.

A null operand short-circuits eq to null — it does not treat null == null as a
match. This aligns with the other ABsmartly SDKs and the collector. Update the
operator tests accordingly.

Approved per request. Missing real HTTP coverage for the public async SDK paths. create_context/publish use reqwest, but tests are synchronous unit tests around builders/context state, with no mock server or tokio HTTP assertions. Please add deterministic tests for GET /context refresh/create and PUT /context publish through the public SDK.

Local server + public async SDK exercises real GET /context and PUT /context,
asserting the wire contract. CI-runnable complement to the live-backend e2e.
publish() sent only X-API-Key, Content-Type, and User-Agent, omitting
X-Application, X-Environment, X-Application-Version:0, and X-Agent that the
collector and the other SDKs use. Add the missing headers and assert the full
set in the integration test.

@Pedro-Revez-Silva Addressed — and your review caught a real bug.

Real HTTP integration test: added `tests/http_integration.rs` (commit `f06ada8`), a tokio local server on 127.0.0.1, driving the public async SDK (`ABsmartly::builder()...build() → create_context().await → treatment + track → publish().await`) so the real reqwest client makes an actual GET /context and PUT /context, asserting the wire contract. CI (`ci.yml`) already runs on `push` + `pull_request`.

Bug it surfaced (fixed in the same commit): the publish PUT only sent `X-API-Key` / `Content-Type` / `User-Agent`, omitting `X-Application`, `X-Environment`, `X-Application-Version:0`, and `X-Agent` that the collector and the other SDKs send. Added the missing headers; the test asserts the full set.
