carrier vs webfakes: at a glance
What is carrier?
carrier's 0.3.0 quietly rewrites how crated functions see each other — and breaks code that relied on the old rules.
carrier packages an R function together with the data it needs so it can be shipped to another process or machine. 0.3.0 changed the semantics of functions passed through ...: they are now re-crated inside the main crate environment instead of inheriting from wherever they were defined. That fixes helper functions failing to resolve each other remotely, and stops local environments dragging large objects into the payload.
What is webfakes?
A fake web server for tests that keeps closing the gap with the real thing.
webfakes runs a real HTTP server inside R tests so packages can exercise network code without hitting the internet. Its releases follow a consistent logic: find a class of behaviour that only the real internet could reproduce, then implement it locally. HTTPS arrived in 1.4.0; before that the httpbin clone reached full parity with the Python original, and a fake git HTTP server landed alongside CGI middleware. The most recent release, 1.5.0, is about the server's own rough edges — keep-alive timeouts, locale-independent HTTP date parsing, and trailing-slash route matching.

carrier's 0.3.0 quietly rewrites how crated functions see each other — and breaks code that relied on the old rules.
◆ Current state
carrier packages an R function together with the data it needs so it can be shipped to another process or machine. 0.3.0 changed the semantics of functions passed through ...: they are now re-crated inside the main crate environment instead of inheriting from wherever they were defined. That fixes helper functions failing to resolve each other remotely, and stops local environments dragging large objects into the payload.
◆ Where it's heading
Each release tightens the boundary between a crate and its surroundings. 0.2.0 introduced .parent_env defaulting to baseenv() to cut the crate off from the global search path and made unnamed ... arguments an error instead of a silent drop; 0.3.0 finishes the job by controlling the environment chain of the packed closures themselves. The package is trading backwards compatibility for predictable, self-contained payloads — a reasonable bet for something whose failures otherwise surface on a remote worker.
◆ Prediction
The 0.1.0 notes promised an automatic dependency-detection mode to replace explicit packing; nothing since has delivered it, and with the environment semantics now settled that is the obvious next move — though the entries give no date for it.

A fake web server for tests that keeps closing the gap with the real thing.
◆ Current state
webfakes runs a real HTTP server inside R tests so packages can exercise network code without hitting the internet. Its releases follow a consistent logic: find a class of behaviour that only the real internet could reproduce, then implement it locally. HTTPS arrived in 1.4.0; before that the httpbin clone reached full parity with the Python original, and a fake git HTTP server landed alongside CGI middleware. The most recent release, 1.5.0, is about the server's own rough edges — keep-alive timeouts, locale-independent HTTP date parsing, and trailing-slash route matching.
◆ Where it's heading
The package is converging on being indistinguishable from a real server for test purposes, which is the only way it stays useful — every unsupported protocol feature is a piece of code someone cannot test offline. The remaining work has visibly shifted from missing endpoints to correctness details: date header parsing under unusual locales, keep-alive tuning, request body handling across content types.
◆ Prediction
Expect continued fidelity work against real-server behaviour rather than new app types, with HTTP/2 or authentication schemes the most plausible next gaps given the direction HTTPS opened. The entries do not indicate a specific planned feature.
