Import new 2-clause BSD licenced implementation of the bc and dc commands
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.
The upstream sources contain a large number of tests, which are not
imported with this commit. They could be integrated into our test
framework at a latter time.
Installation of this version is controlled by the option "MK_GH_BC=yes".
This option will be set to yes by default in 13-CURRENT, but will be off
by default in 12-STABLE.

This `bc` also includes an implementation of `dc` in the same binary, accessible
|
|
|
|
via a symbolic link, which implements all FreeBSD and GNU extensions. (If a
|
|
|
|
standalone `dc` binary is desired, `bc` can be copied and renamed to `dc`.) The

|
|
`!` command is omitted; I believe this poses security concerns and that such

functionality is unnecessary.

## Prerequisites
|
|
|
|
|
|
|
|
This `bc` only requires a C99-compatible compiler and a (mostly) POSIX
|
|
|
|
2008-compatible system with the XSI (X/Open System Interfaces) option group.
|
|
|
|
|
|
|
|
Since POSIX 2008 with XSI requires the existence of a C99 compiler as `c99`, any
|
|
|
|
POSIX and XSI-compatible system will have everything needed.

|
## Build
|
|
|
|
|
|
|
|
This `bc` should build unmodified on any POSIX-compliant system.
|
|
|
|
|
|
|
|
For more complex build requirements than the ones below, see the
|
|
|
|
[build manual][5].
|
|
|
|
|
|
|
|
### Default
|
|
|
|
|
|
|
|
For the default build with optimization, use the following commands in the root
|
|
|
|
directory:
|
|
|
|
|
|
|
|
```
|
|
|
|
./configure.sh -O3
|
|
|
|
make
|
|
|
|
```
|
|
|
|
|
|
|
|
### One Calculator
|
|
|
|
|
|
|
|
To only build `bc`, use the following commands:
|
|
|
|
|
|
|
|
```
|
|
|
|
./configure.sh --disable-dc
|
|
|
|
make
|
|
|
|
```
|
|
|
|
|
|
|
|
To only build `dc`, use the following commands:
|
|
|
|
|
|
|
|
```
|
|
|
|
./configure.sh --disable-bc
|
|
|
|
make
|
|
|
|
```
|
|
|
|
|
|
|
|
### Debug
|
|
|
|
|
|
|
|
For debug builds, use the following commands in the root directory:
|
|
|
|
|
|
|
|
```
|
|
|
|
./configure.sh -g
|
|
|
|
make
|
|
|
|
```
|
|
|
|
|
|
|
|
### Install
|
|
|
|
|
|
|
|
To install, use the following command:
|
|
|
|
|
|
|
|
```
|
|
|
|
make install
|
|
|
|
```
|
|
|
|
|
|
|
|
By default, `bc` and `dc` will be installed in `/usr/local`. For installing in
|
|
|
|
other locations, use the `PREFIX` environment variable when running
|
|
|
|
`configure.sh` or pass the `--prefix=<prefix>` option to `configure.sh`. See the
|
|
|
|
[build manual][5], or run `./configure.sh --help`, for more details.
|
|
|
|
|

|
|
|
### Library
|
|
|
|
|
|
|
|
This `bc` does provide a way to build a math library with C bindings. This is
|
|
|
|
done by the `-a` or `--library` options to `configure.sh`:
|
|
|
|
|
|
|
|
```
|
|
|
|
./configure.sh -a
|
|
|
|
```
|
|
|
|
|
|
|
|
When building the library, the executables are not built. For more information,
|
|
|
|
see the [build manual][5].
|
|
|
|
|
|
|
|
The library API can be found in [`manuals/bcl.3.md`][26] or `man bcl` once the
|
|
|
|
library is installed.
|
|
|
|
|
|
|
|
The library is built as `bin/libbcl.a`.

### Package and Distro Maintainers
|
|
|
|
|
|
|
|
#### Recommended Compiler
|
|
|
|
|
|
|
|
When I ran benchmarks with my `bc` compiled under `clang`, it performed much
|
|
|
|
better than when compiled under `gcc`. I recommend compiling this `bc` with
|
|
|
|
`clang`.
|
|
|
|
|
|
|
|
I also recommend building this `bc` with C11 if you can because `bc` will detect
|
|
|
|
a C11 compiler and add `_Noreturn` to any relevant function(s).
|
|
|
|
|
|
|
|
#### Recommended Optimizations
|
|
|
|
|
|
|
|
I wrote this `bc` with Separation of Concerns, which means that there are many
|
|
|
|
small functions that could be inlined. However, they are often called across
|
|
|
|
file boundaries, and the default optimizer can only look at the current file,
|
|
|
|
which means that they are not inlined.
|
|
|
|
|
|
|
|
Thus, because of the way this `bc` is built, it will automatically be slower
|
|
|
|
than other `bc` implementations when running scripts with no math. (My `bc`'s
|
|
|
|
math is *much* faster, so any non-trivial script should run faster in my `bc`.)
|
|
|
|
|
|
|
|
Some, or all, of the difference can be made up with the right optimizations. The
|
|
|
|
optimizations I recommend are:
|
|
|
|
|
|
|
|
1. `-O3`
|
|
|
|
2. `-flto` (link-time optimization)
|
|
|
|
|
|
|
|
in that order.
|
|
|
|
|
|
|
|
Link-time optimization, in particular, speeds up the `bc` a lot. This is because
|
|
|
|
when link-time optimization is turned on, the optimizer can look across files
|
|
|
|
and inline *much* more heavily.
|
|
|
|
|
|
|
|
However, I recommend ***NOT*** using `-march=native`. Doing so will reduce this
|
|
|
|
`bc`'s performance, at least when building with link-time optimization. See the
|
|
|
|
[benchmarks][19] for more details.
|
|
|
|
|
|
|
|
#### Stripping Binaries
|
|
|
|
|
|
|
|
By default, non-debug binaries are stripped, but stripping can be disabled with
|
|
|
|
the `-T` option to `configure.sh`.
|
|
|
|
|
|
|
|
#### Using This `bc` as an Alternative
|
|
|
|
|
|
|
|
If this `bc` is packaged as an alternative to an already existing `bc` package,
|
|
|
|
it is possible to rename it in the build to prevent name collision. To prepend
|
|
|
|
to the name, just run the following:
|
|
|
|
|
|
|
|
```
|
|
|
|
EXECPREFIX=<some_prefix> ./configure.sh
|
|
|
|
```
|
|
|
|
|
|
|
|
To append to the name, just run the following:
|
|
|
|
|
|
|
|
```
|
|
|
|
EXECSUFFIX=<some_suffix> ./configure.sh
|
|
|
|
```
|
|
|
|
|
|
|
|
If a package maintainer wishes to add both a prefix and a suffix, that is
|
|
|
|
allowed.
|
|
|
|
|
|
|
|
**Note**: The suggested name (and package name) when `bc` is not available is
|
|
|
|
`bc-gh`.
|
|
|
|
|
|
|
|
#### Karatsuba Number
|
|
|
|
|
|
|
|
Package and distro maintainers have one tool at their disposal to build this
|
|
|
|
`bc` in the optimal configuration: `karatsuba.py`.
|
|
|
|
|
|
|
|
This script is not a compile-time or runtime prerequisite; it is for package and
|
|
|
|
distro maintainers to run once when a package is being created. It finds the
|
|
|
|
optimal Karatsuba number (see the [algorithms manual][7] for more information)
|
|
|
|
for the machine that it is running on.
|
|
|
|
|
|
|
|
The easiest way to run this script is with `make karatsuba`.
|
|
|
|
|
|
|
|
If desired, maintainers can also skip running this script because there is a
|
|
|
|
sane default for the Karatsuba number.
|
|
|
|
|
|
|
|
## Status
|
|
|
|
|
|
|
|
This `bc` is robust.
|
|
|
|
|
|
|
|
It is well-tested, fuzzed, and fully standards-compliant (though not certified)
|
|
|
|
with POSIX `bc`. The math has been tested with 40+ million random problems, so
|
|
|
|
it is as correct as I can make it.
|
|
|
|
|
|
|
|
This `bc` can be used as a drop-in replacement for any existing `bc`. This `bc`
|
|
|
|
is also compatible with MinGW toolchains, though history is not supported on
|
|
|
|
Windows.
|
|
|
|
|
|
|
|
In addition, this `bc` is considered complete; i.e., there will be no more
|
|
|
|
releases with additional features. However, it *is* actively maintained, so if
|
|
|
|
any bugs are found, they will be fixed in new releases. Also, additional
|
|
|
|
translations will also be added as they are provided.
|
|
|
|
|
|
|
|
## Comparison to GNU `bc`
|
|
|
|
|
|
|
|
This `bc` compares favorably to GNU `bc`.
|
|
|
|
|
|
|
|
* It has more extensions, which make this `bc` more useful for scripting.
|
|
|
|
* This `bc` is a bit more POSIX compliant.
|
|
|
|
* It has a much less buggy parser. The GNU `bc` will give parse errors for what
|
|
|
|
is actually valid `bc` code, or should be. For example, putting an `else` on
|
|
|
|
a new line after a brace can cause GNU `bc` to give a parse error.
|
|
|
|
* This `bc` has fewer crashes.
|
|
|
|
* GNU `bc` calculates the wrong number of significant digits for `length(x)`.
|
|
|
|
* GNU `bc` will sometimes print numbers incorrectly. For example, when running
|
|
|
|
it on the file `tests/bc/power.txt` in this repo, GNU `bc` gets all the right
|
|
|
|
answers, but it fails to wrap the numbers at the proper place when outputting
|
|
|
|
to a file.
|
|
|
|
* This `bc` is faster. (See [Performance](#performance).)
|
|
|
|
|
|
|
|
### Performance
|
|
|
|
|
|
|
|
Because this `bc` packs more than `1` decimal digit per hardware integer, this
|
|
|
|
`bc` is faster than GNU `bc` and can be *much* faster. Full benchmarks can be
|

|
|
There is one instance where this `bc` is slower: if scripts are light on math.
|
|
|
|
This is because this `bc`'s intepreter is slightly slower than GNU `bc`, but
|
|
|
|
that is because it is more robust. See the [benchmarks][19].

## Algorithms
|
|
|
|
|
|
|
|
To see what algorithms this `bc` uses, see the [algorithms manual][7].
|
|
|
|
|
|
|
|
## Locales
|
|
|
|
|
|
|
|
Currently, this `bc` only has support for English (and US English), French,
|
|
|
|
German, Portuguese, Dutch, Polish, Russian, Japanese, and Chinese locales.
|
|
|
|
Patches are welcome for translations; use the existing `*.msg` files in
|
|
|
|
`locales/` as a starting point.
|
|
|
|
|
|
|
|
In addition, patches for improvements are welcome; the last two messages in
|
|
|
|
Portuguese were made with Google Translate, and the Dutch, Polish, Russian,
|
|
|
|
Japanese, and Chinese locales were all generated with [DeepL][22].
|
|
|
|
|
|
|
|
The message files provided assume that locales apply to all regions where a
|
|
|
|
language is used, but this might not be true for, e.g., `fr_CA` and `fr_CH`.
|
|
|
|
Any corrections or a confirmation that the current texts are acceptable for
|
|
|
|
those regions would be appreciated, too.

## Other Projects
|
|
|
|
|
|
|
|
Other projects based on this bc are:
|
|
|
|
|
|
|
|
* [busybox `bc`][8]. The busybox maintainers have made their own changes, so any
|
|
|
|
bugs in the busybox `bc` should be reported to them.
|
|
|
|
|
|
|
|
* [toybox `bc`][9]. The maintainer has also made his own changes, so bugs in the
|
|
|
|
toybox `bc` should be reported there.

2020-07-07 07:51:09 +00:00
|
|
|
* [FreeBSD `bc`][23]. While the `bc` in FreeBSD is kept up-to-date, it is better
|
2020-08-03 19:20:26 +00:00
|
|
|
to [report bugs there][24], as well as [submit patches][25], and the
|
|
|
|
maintainers of the package will contact me if necessary.

Import new 2-clause BSD licenced implementation of the bc and dc commands
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.
The upstream sources contain a large number of tests, which are not
imported with this commit. They could be integrated into our test
framework at a latter time.
Installation of this version is controlled by the option "MK_GH_BC=yes".
This option will be set to yes by default in 13-CURRENT, but will be off
by default in 12-STABLE.
