Rparadox 0.2.0

New features

• Encryption Support: Added the password argument to read_paradox(). Users can now read password-protected Paradox files (.db) and associated BLOB/Memo files (.MB).
• Enhanced Metadata: pxlib_metadata() now returns human-readable field types (e.g., “Alpha”, “Date”, “Memo”) instead of raw integer codes.
• Encoding info: Metadata now explicitly reports the detected encoding.

Bug fixes and improvements (Core C library)

• Major x64 compatibility update: Integrated patches for the underlying pxlib engine to ensure stability on 64-bit systems.
  • Replaced long int with int32_t in data reading functions to ensure correct data width on 64-bit systems (Windows/Linux).
  • Fixed pointer arithmetic logic in src/px_head.c to prevent undefined behavior and header corruption.
  • Updated writeproc signature to ssize_t for POSIX compliance.

Rparadox 0.1.5

CRAN check Note fix

• remove incorrect CRAN link in Readme.

Rparadox 0.1.4

Cosmetic fixes

• Add misplaced picture link at Readme.Rmd.
• Add pxlib URL to DESCRIPTION file.
• Fix NEWS format.

Rparadox 0.1.3

New features

• Added a high-level read_paradox() function for a simple, one-step workflow to read Paradox files. This is now the recommended function for most users.
• Added a pxlib_metadata() function to retrieve database metadata (number of records, field details, encoding) without reading the entire dataset.

Bug fixes and improvements

• The architecture for handling character encodings has been completely refactored. The C-level code now returns raw character data, and all conversion to UTF-8 is handled reliably in R via the stringi package(ICU) instead of Riconv. This fixes test failures on CRAN and improves robustness for files on various operating systems.
• Added stringi to package imports.
• Added extensive tests for the new read_paradox() and pxlib_metadata() functions.
• Documentation and examples have been updated to reflect the new functions and recommended workflow.

Rparadox 0.1.2

Bug fixes and improvements

• Fixed CRAN check issues on Debian: package no longer attempts to open Paradox files in write mode (rb+ → rb). This ensures full compliance with CRAN Policy (no writes outside of temporary directories).
• Fixed heap-buffer-overflow in PX_get_data_alpha (discovered with AddressSanitizer). Now the function safely respects field length and prevents out-of-bounds reads for fixed-length strings without \0.
• Improved handling of invalid/null Paradox dates with an upper bound filter for extreme values.
• Added proper .gitignore entries for cran-comments.md and CRAN-SUBMISSION.
• Updated README with CRAN badges and installation instructions.
• Expanded test coverage: re-enabled datasets with German, English and Russian encodings, including CP866.

Rparadox 0.1.1

Bug fixes and improvements

• Fixed CRAN feedback:
  • Removed unnecessary \dontrun{} in examples.
    Added fast, self-contained examples using demo files
    (biolife.db, of_cp866.db in inst/extdata).
    
  • Ensured no commented-out example code remains.
  • All examples now run in < 5s and without commented-out code.
• Fixed vignette build issue on CRAN check servers:
  • Explicitly added rmarkdown in VignetteBuilder
    to avoid failures when running with --no-suggests.
• Memory management improvements:
  • Fixed memory leaks in src/interface.c when reading BLOB fields.
  • Examples and vignette now run cleanly under Valgrind.
• Verified that all examples run in < 5 sec and vignettes build
  successfully across test environments.

Rparadox 0.1.0
