nanonext 0.6.0

The nanonext 0.6 series incorporates significant advances in performance and stability over previous releases

New Features

  • Implements base64enc() and base64dec() base64 encoding and decoding using the 'Mbed TLS' library.
  • sha224(), sha256(), sha384() and sha512() functions gain an argument 'convert' to control whether to return a raw vector or character string.
  • ncurl() gains the argument 'follow' (default FALSE) to control whether redirects are automatically followed.

Updates

Please review the following potentially breaking changes, and only update when ready:

  • send() now returns an integer exit code in all cases. The 'echo' argument has been replaced by '...', and specifying 'echo' no longer has any effect.
  • recv(), recv_aio() and request() now default to 'keep.raw' = FALSE to return only the sent object.
  • ncurl() argument 'request' renamed to 'response' for specifying response headers to return (to avoid confusion); new argument 'follow' (placed between 'convert' and 'method') controls whether redirects are followed, and there is no longer a user prompt in interactive environments.
  • sha224(), sha256(), sha384() and sha512() functions no longer return 'nanoHash' objects, but a raw vector or character string depending on the new argument 'convert'.

Other changes:

  • socket() and nano() now accept non-missing NULL 'listen' and 'dial' arguments, allowing easier programmatic use.
  • Functions send(), recv(), send_aio(), recv_aio(), setopt(), subscribe(), unsubscribe() and survey_time() are no longer S3 generics for enhanced performance.
  • messenger() uses longer SHA-512 hash for authentication; fixes errors creating a connnection not being shown.
  • The source code of 'libnng' v1.6.0 pre-release (722bf46) and 'libmbedtls' v3.2.1 now comes bundled rather than downloaded - this is much more efficient as unused portions have been stripped out.
  • Detects and uses system installations of 'libnng' >= 1.6.0 pre-release 722bf46 and 'libmbedtls' >= 2 where available, only compiling from source when required.
  • R >= 4.2 on Windows now performs source compilation of the bundled 'libnng' and 'libmbedtls' using the rtools42 toolchain. Installation falls back to pre-compiled libraries for older R releases.
  • Supported R version amended to >= 2.5, when the current new.env() interface was implemented.
  • Internal performance enhancements.
