Fix a bug in `tac` where multi-character line separators would cause
incorrect behavior when there was overlap between candidate matches in
the input string. This commit adds a dependency on `memchr` in order to
use the `memchr::memmem::rfind_iter()` function to scan for
non-overlapping instances of the specified line separator characters,
scanning from right to left.
Fixes#2580.
* hashsum: support --check for var. length outputs
Add the ability for `hashsum --check` to work with algorithms with
variable output length. Previously, the program would terminate with an
error due to constructing an invalid regular expression.
* fixup! hashsum: support --check for var. length outputs
* tac: correct behavior of -b option
Correct the behavior of `tac -b` to match that of GNU coreutils
`tac`. Specifically, this changes `tac -b` to assume *leading* line
separators instead of the default *trailing* line separators.
Before this commit, the (incorrect) behavior was
$ printf "/abc/def" | tac -b -s "/"
def/abc/
After this commit, the behavior is
$ printf "/abc/def" | tac -b -s "/"
/def/abc
Fixes#2262.
* fixup! tac: correct behavior of -b option

Setting the current directory in tests affects other tests, even if the
change is reverted after, because tests are run in parallel.
This should fix the flaky cp tests.
Since some tests run multiple commands, we have to re-calculate the
expected result for every run.
This is because the expected results depend on file timestamps, but the
files are re-created for every new TestScenario.
If options::WIDTH is not given, we should try to use the terminal width.
If that is unavailable, we should fall back to the 'COLUMNS' environment variable.
If that is unavailable (or invalid), we should fall back to a default of 80.
The following test case read stdin instead of file:
```
echo abcdefg > file
cargo run -- od --format x1 file
```
This is because the -t/--format argument was able to absorb multiple
arguments after it. This has now been fixed, and a test case is added
to ensure it will not happen again.
When hitting Ctrl+C sort now deletes any temporary files. To make this easier I
created a new struct `TmpDirWrapper` that handles the creation of new temporary
files and the registration of the signal handler.
The ToDo list was updated to mark `chcon` as done.
Building and testing `chcon` requires enabling the `feat_selinux` feature. If `make` is used for building, then please specify `SELINUX_ENABLED=1` if building and testing on a system where SELinux is not enabled.
Since sort exits early due to the nonexistent file, it might no longer
be around when we try to send it the input.
This is "by design" and can be ignored.
Fix an issue where `basename` would print the empty path when provided
an input comprising only slashes (for example, "/" or "//" or
"///"). Now it correctly prints the path "/".
In such cases we have to create a temporary copy of the input file to prevent
overwriting the input with the output. This only affects merge sort, because it
is the only mode where we start writing to the output before having read all inputs.
Since lines that compare equal should be sorted together, we need to first
compare the lines (taking settings into account). Only if they do not compare
equal we should compare the hashes.
Add support for
* space-separated list of tab stops, like `--tabs="2 4 6"`,
* mixed comma- and space-separated lists, like `--tabs="2,4 6"`,
* the slash specifier in the last tab stop, like `--tabs=1,/5`,
* the plus specifier in the last tab stop, like `--tabs=1,+5`.
Change the behavior of `tac` when there are no line separators in the
input. Previously, it was appending an extra line separator; this commit
prevents that from happening. The input is now writted directly to
stdout.
Correct the error message produced by `tac` when trying to read from a
directory. Previously if the path 'a' referred to a directory, then
running `tac a` would produce the error message
dir: read error: Invalid argument
after this commit it produces
a: read error: Invalid argument
which matches GNU `tac`.
Handle additional edge cases arising from test(1)’s lack of reserved words.
For example, left parenthesis followed by an operator could indicate
either
* string comparison of a literal left parenthesis, e.g. `( = foo`
* parenthesized expression using an operator as a literal, e.g. `( = != foo )`

The `test_du_bytes` testcase for the `du --bytes` command is written to perform
a dynamic comparison on linux hosts, i.e. it compares the output of the command
to that of the hosts `du` from the GNU coreutils.
Previously the test was written such that it would *first* perform the dynamic
comparison, and *after that* continue to a static comparison which may fail for
specific hosts that have a filesystem different from what the test expects.
This patch excludes linux hosts from the static comparison to ensure the test
performs only the dynamic comparison.
This reimplements version_cmp, which is used in sort and ls to sort
according to versions.
However, it is not bug-for-bug identical with GNU's implementation.
I reported a bug with GNU here:
https://lists.gnu.org/archive/html/bug-coreutils/2021-06/msg00045.html
This implementation does not contain the bugs regarding the handling of
file extensions and null bytes.
`LANGUAGE=C` is not enough, `LC_ALL=C` is needed as the environment
variable that overrides all the other localization settings.
e.g.
```bash
$ LANGUAGE=C id foobar
id: ‘foobar’: no such user
$ LC_ALL=C id foobar
id: 'foobar': no such user
```
* replace `LANGUAGE` with `LC_ALL` as environment variable in the tests
* fix the the date string of affected uutils
* replace `‘` and `’` with `'`
Calling `cmd_keepenv("mv")` spawned the system `mv` instead of
the uutils `mv`. Also, `keepenv` isn't necessary because it doesn't
need to inherit environment variables.
We now actually check the stderr, because previously the result of
`ends_with` was not used, making the test pass even when it shouldn't.
I disabled the test on windows because `mkdir` does not support `-m` on
windows, making the test fail because there will be no permission error.
On FreeBSD there isn't a permission error either, and `mv` succeeds.
On some Windows machines this would otherwise cause `std::env::temp_dir`
to fall back to a path that is not writeable (C:\\Windows).
Since by default integration tests don't inherit env vars from the
parent, we have to override this in some cases.
When invoked via '[' name, last argument must be ']' or we bail out with
syntax error. Then the trailing ']' is simply disregarded and processing
happens like usual.
