Part of the code was transliterated from GNU's implementation in C,
and used flags to store settings. Instead, we can use enums to avoid
magic values or binary operations to extract flags.
- prevent duplicate errors from both us and `walkdir` by instructing `walkdir'
to skip directories we failed to read metadata for.
- don't directly display `walkdir`'s errors, but format them ourselves to
match gnu's format
This way later code can assume `src` and `dest` to be the actual paths
of source and destination, and do not have to constantly check
`options.dereference`.
This requires moving the error context calculation to the beginning as
well, since later steps no longer operate with the same file paths as
supplied by the user.
Fix a mix-up between ownership and mode. The latter (mode / file permissions)
can also be set on windows (which however only affects the read-only flag),
while there doesn't seem to be a straight-forward way to change file ownership
on windows.
Copy the acl as well when copying the mode. This is a non-default feature and can be
enabled with --features feat_acl, because it doesn't seem to work on CI.
It is only available for unix so far.
Copy the SELinux context if possible.
Makes the -o auto option construct a format at initialization, rather
than try to handle it as a special case when printing lines. Fixes bugs
when combined with -e, especially when combined with -a.
Rust recently added new error kinds, which causes tests to fail on beta/nightly.
However, we can't match for these new error kinds because they are marked as unstable.
As a workaround we call `.to_string()` on the original error and strip
the ` (os error XX)` bit. The downside of this is that
the error messages are not capitalized.
* Used .as_path() and .as_str() when required:
when the argument required is a Path and not a PathBuf,
or an str and not a Path, respectively.
* Changed display_items to take Vec<PathData>, which is passed, instead of [PathData]
* Added a pad_right function.
* Implemented column-formating to mimic the behavior of GNU coreutils's ls
Added returns in display_dir_entry_size that keep track of uname and
group lengths.
Renamed variables to make more sense.
Changed display_item_long to take all the lengths it needs to render
correctly.
Implemented owner, group, and author padding right to mimic GNU ls.
* Added a todo for future quality-of-life cache addition.
* Documented display_item_long, as a first step in documenting all functions.
* Revert "Used .as_path() and .as_str() when required:"
This reverts commit b88db6a817.
* Revert "Changed display_items to take Vec<PathData>, which is passed, instead of [PathData]"
This reverts commit 0c690dda8d.
* Ran cargo fmt to get rid of Style/format `fmt` testing error.
* Added a test for `ls -l` and `ls -lan` line formats.
* Changed uname -> username for cspell. Removed extra blank line for rustfmt.
Fix a bug in `seq` where the number of characters needed to print the
number was computed incorrectly in some cases. This commit changes the
computation of the width to be after parsing the number instead of
before, in order to accommodate inputs like `1e3`, which requires four
digits when printing the number, not three.
Combine the `first`, `increment`, and `last` parameters of the
`print_seq()` and `print_seq_integers()` functions into a `RangeF64` or
`RangeInt` type, respectively.
- Implement all of GNU's fiddly little details
- Don't assume Linux for error codes
- Accept badly-encoded filenames
- Report errors after the fact instead of checking ahead of time
- General cleanup
rmdir now passes GNU's tests.
If reading fails midway through then a count should be reported for
what could be read.
If opening a file fails then no count should be reported.
The exit code shouldn't report the number of failures, that's fragile
in case of many failures.
Errors are now always shown with the corresponding filename.
Errors are no longer converted into warnings. Previously `wc < .`
would cause a loop.
Checking whether something is a directory is no longer done in
advance. This removes race conditions and the edge case where stdin is
a directory.
The custom error type is removed because io::Error is now enough.
- Reuse allocations for read lines
- Increase splice size
- Check if /dev/null was opened correctly
- Do not discard read bytes after I/O error
- Add fast line counting with bytecount
Adapt the tests to work with the changed function interfaces. Added a
convenience function to construct a `clap` application that's used to test the
functions from a "user"-perspective.
Change all relevant functions to return `UResult`s from `BackupError` instead
of error strings. Make `determine_backup_mode/suffix` accept `clap::ArgMatches`
as input argument to parse for the arguments themselves, using the arguments
with are defined in the `arguments` submodule.
This way the user only needs to include the pre-defined arguments from the
`arguments` module and passes a reference to the applications `ArgMatches` into
the respective functions here. The functions then take care of handling the
arguments. It is recommended to use the arguments provided in the `arguments`
module over custom-defined ones.
Implements an error type based on `UError` that replaces the previously used
error strings. The errors are currently returned when determining the backup
mode, but extensions for future uses are already in place as comments.
Removes the `return_if_err!` and `safe_unwrap!` macros, which have now
been replaces by `crash_if_err!` throughout the whole code and thus
aren't used any longer.
Unify the usage of macros `return_if_err` and `crash_if_err`. As
`return_if_err` is used only in `uumain` routines of utilities, it
achieves the same thing as `crash_if_err`, which calls the `crash!`
macro to terminate function execution immediately.
Unify the usage of macros `safe_unwrap` and `crash_if_err` that are
identical to each other except for the assumption of a default error
code. Use the more generic `crash_if_err` so that `safe_unwrap` is now
obsolete and can be removed.
Remove a copy operation of the input buffer being read for digest when
reading in text mode on Windows. Previously, the code was copying the
buffer to a completely new `Vec`, replacing "\r\n" with "\n". Instead,
the code now scans for the indices at which each "\r\n" occurs in the
input buffer and inputs into the digest only the characters before the
"\r" and after it.
Report errors properly instead of panicking.
Replace zero_copy by a simpler specialized private module.
Do not assume splices move all data at once.
Use the modern uutils machinery.
Remove the "latency" feature. The time it takes to prepare the buffer
is drowned out by the startup time anyway.
yes: Add tests
yes: Fix long input test on Windows
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
* fixup! tac: correct behavior of -b option

Move the creation of temporary files into next_file so that it happens
while the lock is taken.
Previously, only the computation of the new file path happened while
the lock was taken, while the creation happened later.
csplit fails when suffix has no flags:
$ csplit result.expected -f /tmp/EXPECT -b "%d" "/^## alternative ##$/" {*}
csplit: error: incorrect conversion specification in suffix
This is supported by original csplit
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.
As custom errors are prefered over wrapping around common errors, the
distinction between UCommonError and UCustomError is removed. This
reduces the number of types and makes the error handling easier to
understand.
