mangoro 0.2.5

CRAN Policy Compliance

• Replaced non-suppressible console output (print()/cat()) with message() where appropriate (notably mangoro_go_build()), so information.
• Updated tools/generate_certs.R to avoid writing into the package or user home by default: when no explicit --dir is provided it writes into a temporary directory and reports the chosen path via message(); the script still accepts an explicit --dir for persistent output.
• Added inst/AUTHORS and inst/COPYRIGHTS so vendored components and their license files are easy to find; full license/NOTICE/AUTHORS files remain in the vendor directories.
• Added LICENSE.note summarizing the license types present in vendored code.
• Added Copyright: See inst/AUTHORS to DESCRIPTION to make copyright ownership explicit as requested by CRAN.

mangoro 0.2.4

DESCRIPTION File Updates

• Added single quotes around all software names in Title and Description fields (‘R’, ‘Go’, ‘IPC’, ‘Nanomsg’, ‘nanonext’, ‘nanoarrow’) to comply with CRAN requirements

mangoro 0.2.3

CRAN Policy Compliance

• mangoro_go_build() now sets GOCACHE to a temporary directory by default to prevent populating ~/.cache/go-build during package checks, complying with CRAN policy
• Added gocache parameter to mangoro_go_build() for users who want to specify a custom cache location or use the default Go cache (gocache = NA)
• Maintains backward compatibility while ensuring CRAN compliance

mangoro 0.2.2

CRAN Packaging Improvements

• Fixed long path warnings by relocating flatbuf files during build process
• Flatbuf files now stored in tools/flatbuf/ and restored during package installation via configure script
• Configure scripts updated to be POSIX-compliant (replaced bashisms with standard sh syntax)
• Moved processx from Imports to Suggests (only used in tests)
• Package now passes R CMD check --as-cran with no warnings

Internal Changes

• Updated tools/vendorMangos.sh to move flatbuf files to tools directory after vendoring
• Enhanced configure/configure.win scripts to restore flatbuf files during installation
• Excluded inst/go/vendor/.../flatbuf directory from package tarball via .Rbuildignore

mangoro 0.2.1

RPC Interface

• New rgoipc Go package for type-safe function registration with Arrow schema validation
• RPC protocol wrapping Arrow IPC data with function call envelope
• RPC helper functions: mangoro_rpc_get_manifest(), mangoro_rpc_call(), mangoro_rpc_send(), mangoro_rpc_recv(), mangoro_rpc_parse_response()
• RPC example server demonstrating function registration (add, echoString functions)
• HTTP file server with RPC control interface (start/stop/status commands)
• Helper functions for HTTP server control: mangoro_http_start(), mangoro_http_stop(), mangoro_http_status()

Examples

• Complete RPC function registration and calling example in README
• HTTP server RPC control demonstration with server output capture
• Arrow IPC-based RPC communication examples

mangoro 0.2.0

Initial Release

• R/Go IPC using Nanomsg Next Gen (mangos v3, nanonext)
• Vendored Go dependencies for reproducible builds
• Helper functions to build and run Go binaries from R
• Example echo server and on-the-fly Go compilation from R
• Platform-correct IPC path helpers
• Designed for extensibility and cross-platform use
• We do not cgo’s c-shared mode to avoid loading multiple Go runtimes in the same R session

Arrow Go IPC Support

• Add Arrow Go IPC roundtrip example and support: send and receive Arrow IPC streams between R and Go using nanoarrow and arrow-go.
• New function: get_arrow_go_version() to report the vendored Arrow Go version.
