prrd 0.0.7 at CRAN: Maintenance
A new minor release of prrd arrived at CRAN this morning: the a first release in two and a half years. prrd facilitates the parallel running [of] reverse dependency [checks] when preparing R packages. It is used extensively for releases I make of Rcpp, RcppArmadillo, RcppEigen, BH, and others.
The key idea of prrd is simple, and described in some more detail on its webpage and its GitHub repo. Reverse dependency checks are an important part of package development that is easily done in a (serial) loop. But these checks are also generally embarassingly parallel as there is no or little interdependency between them (besides maybe shared build depedencies). See the (dated) screenshot (running six parallel workers, arranged in a split byobu session).
This release updates continuous intgegration files, switches to Authors@R, and robustifies one SQLite aspect.
The release is summarised in the NEWS entry:
Changes in prrd version 0.0.7 (2026-08-27)
Updates to DESCRIPTION have been made as CRAN requirements change
The continuous integration setup was updated several times
The database connection now uses sqliteSetBusyHandler
Courtesy of my CRANberries, there is also a diffstat report for this release.
