News for package Ropj

Changes in Ropj version 0.3-5 (2024-03-14)

• Updated bundled liborigin, fixing a potential buffer overflow.

Changes in Ropj version 0.3-4 (2023-03-14)

• The package now uses whatever C++ standard is set by default, but may explicitly request C++17, C++14 or C++11 on older versions of R where C++ < 11 was the default.

Changes in Ropj version 0.3-3 (2023-01-08)

• Importing OPJ files containing unsupported objects with tree = TRUE now avoids an error in the R code.

• When decoding strings in the OPJ files, the target encoding is now set to UTF-8, not the native encoding of the R session. This makes it possible to decode strings not representable in the R session encoding, i.e. Windows-1252 files on a Windows-1251 machine and vice versa. Realistically, this is only important on Windows versions older than Windows 10 build 1903.

• A spurious MinGW warning concerning the use of strftime with format strings ⁠%F⁠ and ⁠%T⁠ has been worked around by patching out the call using the preprocessor. (The call wasn't reachable from R code, and the UCRT library currently used by R is documented to support these format strings.)

• Updated bundled liborigin, fixing rare memory access issues.

• A compilation error in ‘tree.hh’ has been fixed by adding an #include to provide the missing global type definition.

Changes in Ropj version 0.3-2 (2022-03-14)

• New tree parameter to return the objects in a tree structure instead of a flat list

Changes in Ropj version 0.2-2 (2019-03-14)

• Prevent truncation of long tables when importing large files

• Fix a memory leak possibly resulting from misuse of tree.hh library
