What is rush?

Rush spent 2026 making distributed task ownership correct, starting with a breaking 1.0.

rush is the Redis-backed distributed computing backend behind mlr3's parallel tuning: workers pull tasks, push results and are tracked through heartbeats. Since 1.0.0 in March 2026 it has shipped five releases in four months, almost all correcting how tasks and workers are owned and identified under failure. The most recent lets each worker start in its own mirai call so it can spawn local daemons.

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.

2.5

Rush spent 2026 making distributed task ownership correct, starting with a breaking 1.0.

◆ Current state

rush is the Redis-backed distributed computing backend behind mlr3's parallel tuning: workers pull tasks, push results and are tracked through heartbeats. Since 1.0.0 in March 2026 it has shipped five releases in four months, almost all correcting how tasks and workers are owned and identified under failure. The most recent lets each worker start in its own mirai call so it can spawn local daemons.

◆ Where it's heading

The through-line is moving responsibility from the controller to the worker. 1.0.0 rewrote the task lifecycle and dropped the seed mechanism; 1.2.0 moved fail_tasks(), finish_tasks(), pop_task() and push_running_tasks() from Rush onto RushWorker so only the worker that ran a task can mark it done, and gave worker ids random suffixes so they cannot collide. 1.1.0 had already removed phantom failed tasks when a worker crashes between evaluations.

◆ Prediction

With ownership and identity settled, the remaining pressure points are heartbeat and lost-worker detection; expect the next releases to tighten failure recovery rather than add API surface.

0.0

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.
