Fix the behavior of truncate when given a non-existent file so that it
correctly creates the file before truncating it (unless the
`--no-create` option is also given).
Fix a bug when getting all but the first NUM lines or bytes of a file
via `tail -n +NUM <file>` or `tail -c +NUM <file>`. The bug only
existed when a file is given as an argument; it did not exist when the
input data came from stdin.
Support `-z` option when the input is not a seekable file. Previously,
the option was accepted by the argument parser, but it was being
ignored by the application logic.
This expands the error message that is printed if either input file has
an unsorted line. Both the program name (join) and the offending line
are printed out with the message to match the behaviour of the GNU
utility.
This commit replaces generic Results with UResults in some key
functions in numfmt. As a result of this, we can provide different
exit codes for different errors, which resolves ~70 failing test
cases in the GNU numfmt.pl test suite.
Fix two issues with the filename creation algorithm. First, this
corrects the behavior of the `-a` option. This commit ensures a
failure occurs when the number of chunks exceeds the number of
filenames representable with the specified fixed width:
$ printf "%0.sa" {1..11} | split -d -b 1 -a 1
split: output file suffixes exhausted
Second, this corrects the behavior of the default behavior when `-a`
is not specified on the command line. Previously, it was always
settings the filenames to have length 2 suffixes. This commit corrects
the behavior to follow the algorithm implied by GNU split, where the
filename lengths grow dynamically by two characters once the number of
chunks grows sufficiently large:
$ printf "%0.sa" {1..91} | ./target/debug/coreutils split -d -b 1 \
> && ls x* | tail

* print error in the correct order by flushing the stdout buffer before printing an error
* print correct GNU error codes
* correct formatting for config.inode, and for dangling links
* correct padding for Format::Long
* remove colors after the -> link symbol as this doesn't match GNU
* correct the major, minor #s for char devices, and correct padding
* improve speed for all metadata intensive ops by not allocating metadata unless in a Sort mode
* new tests, have struggled with how to deal with stderr, stdout ordering in a test though
* tried to implement UIoError, but am still having issues matching the formatting of GNU

Fix a bug in which a negative decimal input would not be displayed with
the correct width in the output. Before this commit, the output was
incorrectly
$ seq -w -.1 .1 .11
-0.1
0.0
0.1
After this commit, the output is correctly
$ seq -w -.1 .1 .11
-0.1
00.0
00.1
The code was failing to take into account that the input decimal "-.1"
needs to be displayed with a leading zero, like "-0.1".
Pad infinity and negative infinity values with spaces when using the
`-w` option to `seq`. This corrects the behavior of `seq` to match that
of the GNU version:
$ seq -w 1.000 inf inf | head -n 4
1.000
inf
inf
inf
Previously, it incorrectly padded with 0s instead of spaces.
* seq: use BigDecimal to represent floats
Use `BigDecimal` to represent arbitrary precision floats in order to
prevent numerical precision issues when iterating over a sequence of
numbers. This commit makes several changes at once to accomplish this
goal.
First, it creates a new struct, `PreciseNumber`, that is responsible for
storing not only the number itself but also the number of digits (both
integer and decimal) needed to display it. This information is collected
at the time of parsing the number, which lives in the new
`numberparse.rs` module.
Second, it uses the `BigDecimal` struct to store arbitrary precision
floating point numbers instead of the previous `f64` primitive
type. This protects against issues of numerical precision when
repeatedly accumulating a very small increment.
Third, since neither the `BigDecimal` nor `BigInt` types have a
representation of infinity, minus infinity, minus zero, or NaN, we add
the `ExtendedBigDecimal` and `ExtendedBigInt` enumerations which extend
the basic types with these concepts.

GNU rm allows the `-r` flag to be specified multiple times, but
uutils/coreutils would previously exit with an error.
I encountered this while attempting to run `make clean` on the
Postgres source tree (github.com/postgres/postgres).
Updates #1663.
