What is dialr?

The R phone-number package stopped only parsing numbers and started asking them where they are.

dialr wraps Google's libphonenumber through rJava, giving R a phone vector class that parses, validates and formats international numbers. It has been quiet since August 2022, when the last release removed a pathology where Java would freeze after enough invalid inputs. The package covers parsing, validation, formatting, and the metadata lookups added in 0.3.0.

What is Skipper?

Skipper trims a 4x memory regression out of routesrv, days after shipping h2c

Zalando's HTTP router ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.63, which stops routesrv holding an uncompressed route tree alongside the compressed buffer: retained memory in the release's own benchmark falls from 30.7 MB to 2.0 MB, undoing most of the 4x increase zone-aware routing had introduced. Around it sit narrow auth repairs, and an eskip parser change that finally accepts negative numeric arguments in predicates and filters.

The R phone-number package stopped only parsing numbers and started asking them where they are.

◆ Current state

dialr wraps Google's libphonenumber through rJava, giving R a phone vector class that parses, validates and formats international numbers. It has been quiet since August 2022, when the last release removed a pathology where Java would freeze after enough invalid inputs. The package covers parsing, validation, formatting, and the metadata lookups added in 0.3.0.

◆ Where it's heading

Two forces shape the history. One is expansion into what libphonenumber knows beyond the number itself — carrier, geocode, timezone — which happened once, in 2019, and has not been extended since. The other is the ongoing cost of being a Java wrapper inside an R tidyverse: rJava initialisation moved so the :: form works, phone vectors reclassified when tibble 3.0.0 changed how it treats list-based classes, and repeated performance work to make crossing the Java boundary tolerable. The maintainer has floated moving the phone class onto vctrs but has not.

◆ Prediction

The vctrs migration is the one change the maintainer has explicitly signalled, and the hard-deprecated one-shot functions were slated for removal in the next major release; three years of silence make neither imminent.

Skipper trims a 4x memory regression out of routesrv, days after shipping h2c

◆ Current state

Zalando's HTTP router ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.63, which stops routesrv holding an uncompressed route tree alongside the compressed buffer: retained memory in the release's own benchmark falls from 30.7 MB to 2.0 MB, undoing most of the 4x increase zone-aware routing had introduced. Around it sit narrow auth repairs, and an eskip parser change that finally accepts negative numeric arguments in predicates and filters.

◆ Where it's heading

Two threads run through the recent tags. The data path keeps getting real work - leastRequests balancing, then h2c end to end in v0.27.57, now the memory cost of zone-aware routing being paid back. The auth filters, by contrast, are only being maintained: token introspection, grant auth, and now the OIDC Referer handling are fixes rather than new capability, and several are follow-ups to each other rather than independent bugs.

◆ Prediction

Zone-aware routing looks like the source of the recent memory attention, so expect further tuning around route storage and the hash computation done on every pull, which the release's second benchmark already isolates. The OIDC cookie change is the second link in an auth chain that started with the grant-auth fix, and is likely to draw another follow-up.
