For any commandline arguments, ls should print the argument as is (and
not truncate to just the file name)
For any other files it reaches (say through recursive exploration), ls
should print just the filename (as path is printed once when we enter
the directory)
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.
Previous version would perform an amount of work proportional to `CHUNK_SIZE`,
so this wasn't a valid way to benchmark at multiple values of that constant.
The `TryInto` implementation for `&mut [T]` to `&mut [T; N]` relies on `const`
generics, and is available in (stable) Rust v1.51 and later.
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.
Refactor code from the `backwards_thru_file()` function into a new
`ReverseChunks` iterator, and use that iterator to simplify the
implementation of the `backwards_thru_file()` function. The
`ReverseChunks` iterator yields `Vec<u8>` objects, each of which
references bytes of a given file.
- 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
Refactor common code out of two branches of the `unbounded_tail()`
function into a new `unbounded_tail_collect()` helper function, that
collects from an iterator into a `VecDeque` and keeps either the last
`n` elements or all but the first `n` elements.
This commit also adds a new struct, `RingBuffer`, in a new module,
`ringbuffer.rs`, to be responsible for keeping the last `n` elements
of an iterator.
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.
Refactor the counting code from the inner loop of the `wc` program
into the `WordCount::from_line()` associated function. This commit
also splits that function up into other helper functions that
encapsulate decoding characters and finding word boundaries from raw
bytes.
This commit also implements the `Sum` trait for the `WordCount`
struct, so that we can simply call `sum()` on an iterator that yields
`WordCount` instances.
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`
FileMerger is much more efficient than the previous algorithm,
which looped over all elements every time to determine the next element.
FileMerger uses a BinaryHeap, which should bring the complexity for
the merge step down from O(n²) to O(n log n).
* 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
Add the `WordCountable::lines()` method that returns an iterator over
lines of a file-like object. This mirrors the
`std::io::BufRead::lines()` method, with some minor differences due to
the particular use case of `wc`.
This commit also creates a new module, `countable.rs`, to contain the
`WordCountable` trait and the new `Lines` struct returned by `lines()`.
Use clap for argument parsing instead of getopts
Also, make the following changes
* Use `executable!()` macro to output the name of utility
* Add another usage to help message
- 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.
It is much faster to just write the lines to disk, separated by \n
(or \0 if zero-terminated is enabled), instead of serializing to json.
external_sort now knows of the Line struct instead of interacting with
it using the ExternallySortable trait. Similarly, it now uses the
crash_if_err! macro to handle errors, instead of bubbling them up.
Some functions were changed from taking &[Line] as the input to taking
an Iterator<Item = Line>. This removes the need to collect to a Vec
when not necessary.
This removes the need to allocate a new string for each line when used
with -f, -d or -i. Instead, a custom string comparison algorithm takes
care of these cases.
The resulting performance improvement is about 20% per flag (i.e. there
is a 60% improvement when combining all three flags)
As a side-effect, the size of the Line struct was reduced from 96 to 80
bytes, reducing the overhead for each line.

* 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.
* Use buffered stdout to reduce write sys calls.
This simple change yielded the biggest performace gain.
* Use `for_byte_record_with_terminator` from the `bstr` crate.
This is to minimize the per line copying needed by
`BufReader::read_until`. The `cut_fields` and `cut_fields_delimiter`
functions used `read_until` to iterate over lines. That required copying
each input line to the line buffer. With
`for_byte_record_with_terminator` copying is minimized as it calls our
closure with a reference to BufReader's buffer most of the time. It
needs to copy (internally) only to process any incomplete lines at the
end of the buffer.
* Re-write `Searcher` to use `memchr`.
Switch from the naive implementation to one that uses `memchr`.
* Rewrite `cut_bytes` almost entirely.
This was already well optimized. The performance gain in this case is
not from avoiding copying. In fact, it needed zero copying whereas new
implementation introduces some copying similar to `cut_fields` described
above. But the occassional copying cost is more than offset by the use
of the very fast `memchr` inside `for_byte_record_with_terminator`.
This change also simplifies the code significantly. Removed the `buffer`
module.
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

Rust 1.40 did not support map_or for result types
Trailing separators were included at the end of the last token, but they
should not be.
This changes tokenize_with_separator as suggested by @cbjadwani.
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.
This reduces memory usage by only storing two lines of the input file at
a time. The current implementation first builds a list of all duplicate
lines ('group') and then decides which lines of the group should be
printed.
- 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: use unstable sort when possible
This results in a very minor performance (speed) improvement.
It does however result in a memory usage reduction, because unstable
sort does not allocate auxiliary memory. There's also an improvement in
overall CPU usage.
* add benchmarking instructions
* add user time
* fix typo
* 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.
* fix leading zeroes for negative numbers
* use more appropriate name for exponent
* improvements to the parse function
* move checks into main loop and fix thousands separator condition

Forgot to handle the case where no arguments were passed to the COMMAND.
Because ARGS can be empty, we need two separate cases for handling
options.values_of(options::ARGS)
Fixed some minor ownership issues in converting from the options to the
arguments to the timeout COMMAND.
Additionally, fixed a rustfmt issue in other files (fold/stdbuf.rs)
Changed from optparse to clap.
None of the logic within timeout has been changed, which could use some
refactoring, but that's beyond the scope of this commit.
refactor `is_wsl` to `is_wsl_1` and `is_wsl_2`

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.
The '-d' flag should create all ancestors (or components) of a
directory regardless of the presence of the "-D" flag.
From the man page:
-d, --directory
treat all arguments as directory names; create all components of the specified directories
With GNU:
$ install -v -d dir1/di2
install: creating directory 'dir1'
install: creating directory 'dir1/di2'
With this version:
$ ./target/release/install -v -d dir3/di4
install: dir3/di4: No such file or directory (os error 2)
install: dir3/di4: chmod failed with error No such file or directory (os error 2)
install: created directory 'dir3/di4'
Also, one of the unit tests misinterprets what a "component" is,
and hence was fixed.
Also don't run chmod when we just failed to create the directory.
Behaviour before this patch:
$ ./target/release/install -v -d dir1/dir2
install: dir1/dir2: Permission denied (os error 13)
install: dir1/dir2: chmod failed with error No such file or directory (os error 2)
install: created directory 'dir1/dir2'

GNU coreutils [1] checks the following: whether
- either file is nonexistent,
- there's a sticky bit or set[ug]id bit in play,
- either file isn't a regular file,
- the sizes of both files mismatch,
- the destination file's owner differs from intended, or
- the contents of both files mismatch.

note this about print:

This PR adds the options to customize what information is shown in long format regarding author, group & owner. Specifically it adds:
- `--author`: shows the author, which is always the same as the owner. GNU has this feature because GNU/Hurd supports a difference between author and owner, but I don't think Rust supports GNU/Hurd, so I just used the owner.
- `-G` & `--no-group`: hide the group information.
- `-o`: hide the group and use long format (equivalent to `-lG`).
- `-g`: hide the owner and use long format.
The `-o` and `-g` options have some interesting behaviour that I had to account for. Some examples:
- `-og` hides both group and owner.
- `-ol` still hides the group. Same behaviour with variations such as `-o --format=long`, `-gl`, `-g --format=long` and `-ogl`.
- They even retain some information when overridden by another format: `-oCl` (or `-o --format=vertical --format=long`) still hides the group.
My previous solution for handling the behaviour where `-l1` shows the long format did not fit with these additions, so I had to rewrite that as well.
The tests only cover the how many names (author, group and owner) are present in the output, so it can't distinguish between, for example, author & group and group & owner.
It was a draft PR, not ready for merging, and its premature inclusion
caused repeated issues, see 368f47381b & friends.

* date: implement set date for unix and windows
Parsing the date string is not fully implemented yet, as in it relies
on the internals of chrono - things like "Mon, 14 Aug 2006 02:34:56 -0600"
do not work, nor does "2006-08-14 02:34:56" (no TZ / local time). This
is no different to using the "--date" option however, and will get fixed
when `parse_date` is a bit smarter.
Only supports unix and Windows platforms for now.

Current implementation of the skip fields logic does not handle
multibyte code points correctly. It assumes each code point (`char`) is
one byte. If the skipped part of the input line has any multibyte code
points then this can cause fields not being skipped correctly (field
start index is calculated to be before it actually starts).

When converting to SI or IEC, produce values that align with the conventions
used by GNU numfmt.
- values > 10 are represented without a decimal place, so 10000 becomes 10K
instead of 10.0K
- when truncating, take the ceiling of the value, so 100001 becomes 101K
- values < 10 are truncated to the highest tenth, so 1001 becomes 1.1K
closes#1726
Adjust header option handling to prohibit passing a value of 0 to align
with GNU numfmt. Also report header option parse errors as GNU does.
closes#1708
Align with GNU numfmt by trimming leading whitespace from supplied values.
If the user did not specify a padding, calculate an implied padding from
the leading whitespace and the value.
Also track closer to GNU numfmt’s error message format.
Previously if no --color argument was input, we would always print
colors in the output. This breaks `configure` scripts which run `ls`
and then compare the output against what they expect to see, since the
left side has ANSI escape sequences and the right side doesn't.
Instead, only print escape sequences if a TTY is present, or if
`--color=always` is specified.
Fixes#1638.
