What is logrx?

A clinical-script logger that stopped shipping after its 0.2 line, changelogs made of merged PRs.

logrx produces execution logs for R scripts in regulated clinical work, recording what ran, what it returned, and which unapproved packages or functions were used. Its release notes are raw merged-PR lists rather than written changelogs, which makes the substance hard to read from the feed. The most recent release, 0.2.2 in June 2023, exists to track tidyselect and dplyr changes.

What is mirai?

mirai removed its dispatcher process and added memory backpressure to the queue.

The async evaluation framework releases roughly monthly and moves fast at the architecture level. In 2.7.0 the dispatcher stopped being a separate process and became a thread, after its loop had already been rewritten in C inside nanonext one release earlier. The same release added an opt-in memory budget for queued task payloads and try_mirai(), which returns NULL immediately rather than blocking when that budget is exhausted.

logrx vs mirai: editorial side-by-side

0.0

A clinical-script logger that stopped shipping after its 0.2 line, changelogs made of merged PRs.

◆ Current state

logrx produces execution logs for R scripts in regulated clinical work, recording what ran, what it returned, and which unapproved packages or functions were used. Its release notes are raw merged-PR lists rather than written changelogs, which makes the substance hard to read from the feed. The most recent release, 0.2.2 in June 2023, exists to track tidyselect and dplyr changes.

◆ Where it's heading

Feature work concentrated in the 0.1 line — return codes, a results writer, a to_report parameter, and logging of unapproved package and function use — and the 0.2 releases have been compatibility maintenance and hotfixes. Three years of silence in a pharmaverse that has otherwise kept shipping suggests the package reached the shape its users needed rather than that it was abandoned mid-design.

◆ Prediction

Nothing in these entries points to planned work; the likeliest trigger for a release is a breaking change in tidyverse dependencies, which is what produced the last one.

2.5

mirai removed its dispatcher process and added memory backpressure to the queue.

◆ Current state

The async evaluation framework releases roughly monthly and moves fast at the architecture level. In 2.7.0 the dispatcher stopped being a separate process and became a thread, after its loop had already been rewritten in C inside nanonext one release earlier. The same release added an opt-in memory budget for queued task payloads and try_mirai(), which returns NULL immediately rather than blocking when that budget is exhausted.

◆ Where it's heading

Two threads of work run together: cutting overhead out of the task path — thread-based dispatcher, in-process transport for synchronous daemons, lower per-element dispatch cost in mirai_map() — and making the framework safe to embed in an event loop, where blocking the host R thread is not acceptable. Deployment reach is growing too, with http_config() launching remote daemons over HTTP APIs and auto-configuring for Posit Workbench. Each release pins a minimum nanonext version, so the two packages advance as one unit.

◆ Prediction

With backpressure in place but opt-in, the open question these notes leave is whether a default memory budget arrives; continued overhead reduction and Shiny-facing non-blocking paths are the safer bet.
