dst may or may not exist. In case it exists it might already be a symlink.
In neither case we should try to canonicalize dst, only its parent directory.

We were reporting "no match" when sorting something like "0 ". This is
because we don't distinguish between 0 and invalid lines when sorting.
For debug output we have to get this information back.
GNU seq does not support -t, but always outputs a newline at the end.
Therefore, our default for -t should be \n.
Also removes support for escape sequences (interpreting a literal "\n"
as a newline). This is not what GNU seq is doing, and unexpected.
If we notice that we can represent all arguments as BigInts, take a
different code path. Just like GNU seq this means we can print an
infinite amount of numbers in this case.

This commit fixes this minor inconsistency and adds corresponding test.
Closes#2254. We should only inherit global settings for keys when there
are absolutely no options attached to the key.
The default key (matching the whole line) is implicitly added only if no
keys are supplied.
Improved some error messages by including more context.
* expr: support arbitrary precision integers
Instead of i64s we now use BigInts for integer operations. This means
that no result or input can be out of range.
The representation of integer flags was changed from i64 to u8 to make
their intention clearer.
* expr: allow big numbers as arguments as well
Also adds some tests
* expr: use num-traits to check bigints for 0 and 1
* expr: remove obsolete refs
match ergonomics made these avoidable.

* sort: crash when failing to open an input file
Instead of ignoring files we fail to open, crash.
The error message does not exactly match gnu, but that would require
more effort.
* use split_whitespace instead of a manual implementation
* fix expected error on windows
* sort: update expected error message
* sort: disable support for thousand separators
In order to be compatible with GNU, we have to disable thousands
separators. GNU does not enable them for the C locale, either.
Once we add support for locales we can add this feature back.
* sort: delete unused fixtures
* sort: compare -0 and 0 equal
I must have misunderstood this when implementing, but GNU considers
-0, 0, and invalid numbers to be equal.
* sort: strip blanks before applying the char index
* sort: don't crash when key start is after key end
* sort: add "no match" for months at the first non-whitespace char
We should put the "^ no match for key" indicator at the first
non-whitespace character of a field.
* sort: improve support for e notation
* sort: use maches! macros
Add some abstractions to simplify the `rbuf_but_last_n_lines()`
function, which implements the "take all but the last `n` lines"
functionality of the `head` program. This commit adds
- `RingBuffer`, a fixed-size ring buffer,
- `ZLines`, an iterator over zero-terminated "lines",
- `TakeAllBut`, an iterator over all but the last `n` elements of an
iterator.
These three together make the implementation of
`rbuf_but_last_n_lines()` concise.
Fails from time to time with

`sort` supports three ways to specify the sort mode: a long option
(e.g. --numeric-sort), a short option (e.g. -n) and the sort flag
(e.g. --sort=numeric).
This adds support for the sort flag.
Additionally, sort modes now conflict, which means that an error is
shown when multiple modes are passed, instead of silently picking a mode.
For consistency, I added the `random` sort mode to the `SortMode` enum,
instead of it being a bool flag.
Instead of overflowing when calculating the buffer size, use
saturating_{pow, mul}.
When failing to parse the buffer size, we now crash instead of silently
ignoring the error.
To make this work we make default sort a special case of external sort.
External sorting uses auxiliary files for intermediate chunks. However,
when we can keep our intermediate chunks in memory, we don't write them
to the file system at all. Only when we notice that we can't keep them
in memory they are written to the disk.
Additionally, we don't allocate buffers with the capacity of their
maximum size anymore. Instead, they start with a capacity of 8kb and are
grown only when needed.
This makes sorting smaller files about as fast as it was before
(I'm seeing a regression of ~3%), and allows us to seamlessly continue
with auxiliary files when needed.
A lot of tests depend on GNU's coreutils to be installed in order
to obtain reference values during testing.
In these cases testing is limited to `target_os = linux`.
This PR installs GNU's coreutils on "github actions" and adjusts the
tests for `who`, `stat` and `pinky` in order to be compatible with macOS.
* `brew install coreutils` (prefix is 'g', e.g. `gwho`, `gstat`, etc.
* switch paths for testing to something that's available on both OSs,
e.g. `/boot` -> `/bin`, etc.
* switch paths for testing to the macOS equivalent,
e.g. `/dev/pts/ptmx` -> `/dev/ptmx`, etc.
* exclude paths when no equivalent is available,
e.g. `/proc`, `/etc/fstab`, etc.
* refactor tests to make better use of the testing API
* fix a warning in utmpx.rs to print to stderr instead of stdout
* fix long_usage text in `who`
* fix minor output formatting in `stat`
* the `expected_result` function should be refactored
to reduce duplicate code
* more tests should be adjusted to not only run on `target_os = linux`
Fix a bug in which the incorrect character was being used to indicate
"round up to the nearest multiple" mode. The character was "*" but it
should be "%". This commit corrects that.
Change the error message for when the reference file (the `-r` argument)
is not found to match GNU coreutils. This commit also eliminates a
redundant call to `File::open`; the file need not be opened because the
size in bytes can be read from the result of `std::fs::metadata()`.
Change the interface provided by the `parse_size()` function to reduce
its responsibilities to just a single task: parsing a number of bytes
from a string of the form '123KB', etc. Previously, the function was
also responsible for deciding which mode truncate would operate in.
Furthermore, this commit simplifies the code for parsing the number and
unit to be less verbose and use less mutable state.
Finally, this commit adds some unit tests for the `parse_size()`
function.
Change the behavior of `head` to display an error for each problematic
file, instead of displaying an error message for the first problematic
file and terminating immediately at that point. This change now matches
the behavior of GNU `head`.
Before this commit, the first error caused the program to terminate
immediately:
$ head a b c
head: error: head: cannot open 'a' for reading: No such file or directory
After this commit:
$ head a b c
head: cannot open 'a' for reading: No such file or directory
head: cannot open 'b' for reading: No such file or directory
head: cannot open 'c' for reading: No such file or directory
Instead of using a BufReader and reading each line separately,
allocating a String for each one, we read to a chunk. Lines are
references to this chunk. This makes the allocator's job much easier
and yields performance improvements.
Chunks are read on a separate thread to further improve performance.
Fix a bug in which `head` failed to print headings for `stdin` inputs
when reading from multiple files, and fix another bug in which `head`
failed to print a blank line between the contents of a file and the
heading for the next file when reading multiple files. The output now
matches that of GNU `head`.
Fix two issues with the string formatting width for counts displayed
by `wc`.
First, the output was previously not using the default minimum width
(seven characters) when reading from `stdin`. This commit corrects
this behavior to match GNU `wc`. For example,
$ cat alice_in_wonderland.txt | wc
5 57 302
Second, if at least 10^7 bytes were read from `stdin` *after* reading
from a smaller regular file, then every output row would have width
8. This disagrees with GNU `wc`, in which only the `stdin` row and the
total row would have width 8. This commit corrects this behavior to
match GNU `wc`. For example,
$ printf "%.0s0" {1..10000000} | wc emptyfile.txt -
0 0 0 emptyfile.txt
0 1 10000000
0 1 10000000 total
Fixes#2186.
Change the error messages that get printed to `stderr` for compatibility
with GNU `wc` when an input is a directory and when an input does not
exist.
Fixes#2211.
This closes#2181.
`who --lookup` is failing with a runtime panic (double free).
Since `crate::dns-lookup` already includes a safe wrapper for `getaddrinfo`
I used this crate instead of further debugging the existing code in
utmpx::canon_host().
* It was neccessary to remove the version constraint for libc in uucore.
- add `==` as undocumented alias of `=`
- handle negated comparison of `=` as literal
- negation generally applies to only the first expression of a Boolean chain,
except when combining evaluation of two literal strings
When merging files we need to prioritize files that occur earlier in the
command line arguments with -m.
This also makes the extsort merge step (and thus extsort itself) stable again.
This is a refactor to reduce duplicate code, it affects chmod/ls/stat.
* merge `stat/src/fsext::pretty_access` into `uucore/src/lib/feature/fs::display_permissions_unix`
* move tests for `fs::display_permissions` from `test_stat::test_access` to `uucore/src/lib/features/fs::test_display_permissions`
* adjust `uu_chmod`, `uu_ls` and `uu_stat` to use `uucore::fs::display_permissions`
* ls: Implement total size feature
- Implement total size reporting that was missing
- Fix minor formatting / readability nits
* tests: Add tests for ls total sizes feature
* ls: Fix MSRV build errors due to unsupported attributes for if blocks
* ls: Add windows support for total sizes feature
- Add windows support (defaults to file size as block sizes related
infromation is not avialable on windows)
- Renamed some functions
- Replace the parser with a recursive descent implementation that handles
parentheses and produces a stack of operations in postfix order.
Parsing now operates directly on OsStrings passed by the uucore framework.
- Replace the dispatch mechanism with a stack machine operating on the
symbol stack produced by the parser.
- Add tests for parenthesized expressions.
- Begin testing character encoding handling.
Moved argument parsing to clap and added tests to cover using "-" as
stdin, passing in too many file arguments, and updated the "wrap" error
message in the tests.

* ls: ignore leading period when sorting by name
ls now behaves like GNU ls with respect to sorting files by ignoring
leading periods when sorting by main.
Added tests to ensure "touch a .a b .b ; ls" returns ".a a .b b"
* Replaced clone/collect calls.
This adds a --debug flag, which, when activated, will draw lines below
the characters that are actually used for comparisons.
This is not a complete implementation of --debug. It should, quoting the man page
for GNU sort: "annotate the part of the line used to sort, and warn
about questionable usage to stderr". Warning about "questionable usage"
is not part of this patch.
This change required some adjustments to be able to get the range that
is actually used for comparisons. Most notably, general numeric comparisons
were rewritten, fixing some bugs along the lines.
Testing is mostly done by adding fixtures for the expected debug output of
existing tests.
* ls: Remove allocations by eliminating collect/clones
* ls: Introduce PathData structure
- PathData will hold Path related metadata / strings that are required
frequently in subsequent functions
- All data is precomputed and cached and subsequent functions just
use cached data
* ls: Cache more data related to paths
- Cache filename and sort by filename instead of full path
- Cache uid->usr and gid->grp mappings

* ls: Add BENCHMARKING.md
* ls: Document PathData structure
* tests/ls: Add testcase for error paths with width option
* ls: Fix unused import warning
cached will be only used for unix currently as current use of
caching gid/uid mappings is only relevant on unix
* ls: Suggest checking syscall count in BENCHMARKING.md
* ls: Remove mentions of sort in BENCHMARKING.md
* ls: Remove dependency on cached
Implement caching using HashMap and lazy_static
* ls: Fix MSRV error related to map_or
Rust 1.40 did not support map_or for result types
GNU sort disallows these combinations, presumably because they are
likely not what the user really wants.
Ignoring characters would cause things to be put together that aren't
together in the input. For example, -dn would cause "0.12" or "0,12" to
be parsed as "12" which is highly unexpected and confusing.
- Passing `never` to `--reflink` does not raise an error anymore.
- Remove `Options::reflink` flag as it was redundant with
`reflink_mode`.
- Add basic tests for this option. Does not check that a copy-on-write
rather than a regular copy was made.
* sort: implement numeric string comparison
This implements -n and -h using a string comparison algorithm instead
of parsing each number to a f64 and comparing those.
This should result in a moderate performance increase and eliminate loss
of precision.
* cache parsed f64 numbers
For general numeric comparisons we have to parse numbers as f64,
as this behavior is explicitly documented by GNU coreutils.
We can however cache the parsed value to speed up comparisons.

* if we want to test an irregular scenario, ignoring errors caused by
writing to stdin of the command can be uselful.
* for example, when writing some text to stdin of cksum in a scenario
where it doesn't consume this input, the child process might have
exited before the text was written. therefore, this test sometimes
fails with a 'Broken pipe'.
* Replace outdated time 0.1 dependancy with latest version of chrono
I also noticed that times are being miscalculated on linux, so I fixed that.
* Add time test for issue #2042
* Cleanup use declarations
* Tie time test to `touch` feature
- if we compile with the right OS feature flag then we should have it,
even on Windows
refactor `is_wsl` to `is_wsl_1` and `is_wsl_2`
On my tests with wsl2 ubuntu2004 all tests pass without special cases
I moved wsl detection into uucore so that it can be shared instead of duplicated
I moved `parse_mode` into uucode as it seemed to fit there better and anyway requires libc feature
Treat tab chars as advancing to the next tab stop rather than having a fixed
8-column width.
Also treat tab as a whitespace split target only when splitting on word
boundaries.
