This update fixes a few bugs: - Improper response to double SIGINT with editline. - Not letting libedit handle terminal size changes. - A dc crash from improperly handling an error. - A duplicate check for reference arrays. - Build failures with GCC 15.
This is a production release to fix three bugs, none of which affects well formed scripts on FreeBSD: The first bug is that bc/dc will exit on macOS when the terminal is resized. The second bug is that an array, which should only be a function parameter, was accepted as part of larger expressions. The third bug is that the value stack for dc was cleared on any error. However, this is not how other dc behave. To bring dc more in line with other implementations, this behavior was changed. This change is why this version is a new major version.
This update fixes a potential issue when flushing stdout on exit fails: longjmp could use an uninitialized target address variable. Most files are included in this commit due to a changed date in the copyright note.
This is a production release with a new feature and a few bug fixes. The bug fixes include: - A crash when bc and dc are built using editline, but history is not activated. - A missing local in the uint*() family of functions in the extended math library. - A failure to clear the tail call list in dc on error. - A crash when attempting to swap characters in command-line history when no characters exist. - SIGWINCH was activated even when history was not. The new feature is that stack traces are now given for runtime errors. In debug mode, the C source file and line of errors are given as well.
This version adds support for command line editing and history using the editline or readline libraries in addition to the line editing features available in previous versions.
This is a new major release with a number of changes and extensions: - Limited the number of temporary numbers and made the space for them static so that allocating more space for them cannot fail. - Allowed integers with non-zero scale to be used with power, places, and shift operators. - Added greatest common divisor and least common multiple to lib2.bc. - Made bc and dc UTF-8 capable. - Added the ability for users to have bc and dc quit on SIGINT. - Added the ability for users to disable prompt and TTY mode by environment variables. - Added the ability for users to redefine keywords. - Added dc's modular exponentiation and divmod to bc. - Added the ability to assign strings to variables and array elements and pass them to functions in bc. - Added dc's asciify command and stream printing to bc. - Added bitwise and, or, xor, left shift, right shift, reverse, left rotate, right rotate, and mod functions to lib2.bc. - Added the functions s2u(x) and s2un(x,n), to lib2.bc.
This release fixes a regression from traditional bc behavior in FreeBSD with regard to "-e quit" being passed on the command line and add Spanish message catalogs.
These implementations of the bc and dc programs offer a number of advantages compared to the current implementations in the FreeBSD base system: - They do not depend on external large number functions (i.e. no dependency on OpenSSL or any other large number library) - They implements all features found in GNU bc/dc (with the exception of the forking of sub-processes, which the author of this version considers as a security issue). - They are significantly faster than the current code in base (more than 2 orders of magnitude in some of my tests, e.g. for 12345^100000). - They should be fully compatible with all features and the behavior of the current implementations in FreeBSD (not formally verified). - They support POSIX message catalogs and come with localized messages in Chinese, Dutch, English, French, German, Japanese, Polish, Portugueze, and Russian. - They offer very detailed man-pages that provide far more information than the current ones.
