rladybugdb 0.4.4

CRAN documentation

Added return-value documentation for interval formatting and all documented DBI methods, including output classes, contents, and side effects. Clarified return values for result streaming, resource management, and conversions.
Unwrapped short in-memory examples, guarded the graph example with requireNamespace(), and added explicit result and connection cleanup.
Removed the deprecated installation-helper example and installation commands from optional-dependency error messages. Functions, examples, and vignettes do not install packages or external software.

The configure script no longer forwards R’s diagnostic flags (-Wall, -pedantic, and related) to the bundled LadybugDB build. The vendored third-party sources use documented compiler extensions that produced significant-warning output on Debian Clang. All other configured flags, including optimisation, debugging, architecture, hardening, and sanitizer settings, are still passed through, and this package’s own sources continue to be compiled with R’s full flags.

Added a configure-time C++20 link test for LadybugDB’s 16-byte atomic operations. The package now links libatomic only on toolchains that require it, fixing package loading with Debian Clang 23 while remaining portable to platforms that provide the operations natively.

Added explicit fixed-width integer declarations for bundled Thrift so the source builds with the stricter Clang 23 headers used by Debian R-devel.
Fixed bundled CRoaring inline linkage for Rtools/MinGW and restricted the MSVC structured-exception translator to MSVC builds.
Rtools builds now use LadybugDB’s malloc-backed buffer manager, avoiding reliance on MSVC structured exception handling under MinGW.

Replaced downloaded precompiled libraries with a pinned, checksum-verified LadybugDB source archive that is compiled by R’s C++20 toolchain.
Added a small documented upstream portability patch so linked code does not call process-terminating functions, system RNGs, or write directly to stdout/stderr. Remote extension installation is disabled in this build, removing the native OpenSSL runtime dependency.

Updated the embedded engine from LadybugDB 0.15.2 to 0.20.4. Platform artifacts and matching headers are selected for macOS, Linux, and Windows and verified against pinned SHA-256 checksums.
Linked the upstream static library on macOS and Linux, eliminating the local @rpath/liblbug.dylib development failure. Windows installs its matching runtime DLL through install.libs.R.
Result, connection, and database ownership is now explicit. Closed-handle, live-child, finalizer, and double-close paths are checked natively.
Fixed R-devel/Windows compilation by passing explicit Rboolean values to Arrow external-pointer finalizers.
Fixed Windows loading by installing the checksum-verified OpenSSL runtime DLLs required by the upstream LadybugDB DLL.
Added a persisted 0.15.2 compatibility fixture and migration guidance.

as.data.frame() is repeatable and print()/format() use a bounded, non-consuming preview.
Added lb_fetch(), lb_has_next(), lb_reset(), lb_result_info(), lb_query_summary(), and lb_next_result() for streaming and multi-result queries.
Named parameters now require unique, non-empty names. All typed R missing scalars bind as database NULL, and binding failures identify the parameter in a typed error.
Added parameter support for dates, timestamps, integer64, raw bytes, lists, arrays, and structs.
Added exact DECIMAL and INT128 output, configurable INT64/UINT64 handling, raw BLOB output, UTC timestamp handling, and structured INTERVAL, UNION, and recursive-path values.

Added native Arrow C Data Interface export, chunked Arrow fetching, Arrow table registration, and lb_copy_from_arrow(). Data-frame loading prefers Arrow and retains CSV as an explicit fallback.
Added a DBI driver with connection, query, binding, fetch, transaction, quoting, and table metadata methods.
Added query timeout, interruption, transaction, scoped-connection, database configuration, and extension management helpers.
Graph conversion now handles recursive paths, empty results, null-leading columns, multiple labels and relationship types, isolated nodes, and exact internal identifiers.

Removed tracked compiler output and the old bundled dylib, regenerated Rcpp and R documentation, and excluded development-only assets from source builds.
Added cross-platform R CMD check and native sanitizer CI jobs, installed examples, and extension and storage-migration vignettes.

Replaced the original Python/reticulate backend with native Rcpp bindings to LadybugDB 0.15.2.
