* 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
https://github.com/uutils/coreutils/pull/2099/files
* 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
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
* remove unneeded checks
* rustfmt
* du error output should match GNU
* Created a new error macro which allows the customization of the
"error:" string part
* Match the du output based on the type of error encountered. Can extend
to handling other errors I guess.

* 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
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`
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.
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'
* Issue #1622 port `du` to windows
* Attempt to support Rust 1.32
Old version was getting "attributes are not yet allowed on `if`
expressions" on Rust 1.32
* Less #[cfg]
* Less duplicate code.
I need the return and the semicolon after if otherwise the second #[cfg]
leads to unexpected token complilation error
* More accurate size on disk calculations for windows
* Expect the same output on windows as with WSL
* Better matches output from du on WSL
* In the absence of feedback I'm disabling these tests on Windows.
They require `ln`. Windows does not ship with this utility.
* Use the coreutils version of `ln` to test `du`
`fn ccmd` is courtesy of @Artoria2e5
* Look up inodes (file ids) on Windows
* One more #[cfg(windows)] to prevent unreachable statement warning on linux

* cat: Don't double buffer stdout
* cat: Don't use experimental or-pattern syntax

* wc: Increment error count when stats fail to print
* Re-add Cargo.lock
* Implemented --indicator-style flag on ls.
* Rust fmt
* Grouped indicator_style args.
* Added tests for sockets and pipes.
Needed to modify util.rs to add support for pipes (aka FIFOs).
* Updated util.rs to remove FIFO operations on Windows
* Fixed slight error in specifying (not(windows))
* Fixed style violations and added indicator_style test for non-unix systems
+ aligned 'tee' output with GNU tee when one of the files is '/dev/full'
+ don't stop tee when one of the outputs fails; just continue and return
error status from tee in the end

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.

* Add test: non-regular files
* Forgot a #[test]
* Give up on non-regular file test
* `cargo fmt` install.rs
Previously this used `print` instead of `println`, and as a result the
prompt would never appear and the command would hang. The Rust docs
note this about print:
> Note that stdout is frequently line-buffered by default so it may be
> necessary to use io::stdout().flush() to ensure the output is emitted
> immediately.
Changing to `println` fixes the issue.
Fixes#1889.
