What is httr2?

httr2 is growing production concerns: tracing, throttling and token hygiene.

httr2 is the tidyverse's modern HTTP client and the designated successor to httr. Recent releases have moved past request-building ergonomics into operational concerns — OpenTelemetry traces for every request, throttling that behaves correctly across repeated calls, and a fix for OAuth token caches that were never actually being pruned.

What is processx?

processx adds kernel-level process pipelines after years of defensive fixes.

processx is the low-level subprocess engine underneath callr and much of the r-lib tooling stack. For several releases it shipped only hardening work: RNG hygiene, safer format strings, signal handling around terminated parents. Version 3.9.0 breaks that pattern with an experimental pipeline class.

httr2 is growing production concerns: tracing, throttling and token hygiene.

◆ Current state

httr2 is the tidyverse's modern HTTP client and the designated successor to httr. Recent releases have moved past request-building ergonomics into operational concerns — OpenTelemetry traces for every request, throttling that behaves correctly across repeated calls, and a fix for OAuth token caches that were never actually being pruned.

◆ Where it's heading

The package is maturing into infrastructure for long-running R services rather than interactive scripts. The 1.2.0 lifecycle purge removed deprecated streaming and mocking APIs in favour of a connection-based model, and debugging affordances like httr2_translate() point at users who need to reproduce a failing request outside R.

◆ Prediction

Expect further observability and credential-handling work, with the rlang-driven cache hash change in 1.3.0 likely to surface follow-up issues as existing caches silently invalidate.

0.0

processx adds kernel-level process pipelines after years of defensive fixes.

◆ Current state

processx is the low-level subprocess engine underneath callr and much of the r-lib tooling stack. For several releases it shipped only hardening work: RNG hygiene, safer format strings, signal handling around terminated parents. Version 3.9.0 breaks that pattern with an experimental pipeline class.

◆ Where it's heading

The package is moving from running one subprocess reliably toward orchestrating graphs of them, with bytes flowing between children through kernel pipes rather than being relayed through R. The new linux_pdeathsig argument points the same way, giving callers real lifecycle control over long-running children.

◆ Prediction

Expect the pipeline class to lose its experimental label and gain callr integration if the API holds up across both Unix and Windows.
