This commit corrects the behavior of `cp --parents --verbose` when the
source path is a file so that it prints the copied ancestor
directories. For example,
$ mkdir -p a/b d
$ touch a/b/c
$ cp --verbose --parents a/b/c d
a -> d/a
a/b -> d/a/b
'a/b/c' -> 'd/a/b/c'
Fixes#3332.
When copying the contents of a named pipe (also known as a FIFO) via
cp --preserve=ownership --copy-contents fifo fifo-copy
limit the permissions of the destination file while the contents are
being copied, and then restore the permissions to match those of the
source FIFO when all contents have been copied successfully.
Adjust the rendering of the concise byte counts in both SI and IEC
units to better match the behavior of GNU dd.
Before this commit,
$ head -c 1024 /dev/zero | dd > /dev/null
2+0 records in
2+0 records out
1024 bytes (1 KB, 1024 B) copied, 0.0 s, 1.0 MB/s
After this commit,
$ head -c 1024 /dev/zero | dd > /dev/null
2+0 records in
2+0 records out
1024 bytes (1.0 kB, 1.0 KiB) copied, 0.0 s, 1.0 MB/s
For comparison, GNU dd produces the following:
$ head -c 1024 /dev/zero | dd > /dev/null
2+0 records in
2+0 records out
1024 bytes (1.0 kB, 1.0 KiB) copied, 0.000332864 s, 3.1 MB/s
Prevent a panic in `cp -a` when the target of a hard link already
exists in the target directory structure.
For example,
$ mkdir -p src dest/src
$ touch src/f dest/src/f
$ ln src/f src/link
$ cp -a src dest
The `cp` command now succeeds without error.
Summary:
* Disable test_retry6 on android because of intermittent failures
* Use wait() instead of wait_with_output in test_cat, test_cp, test_sort
* tests/sort: Simplify usage of test_sigpipe_panic
* Fix tests in test_tee.
tests/tac:
There was a change in the `tests/common/util.rs` test api concerning piped input which may have
revealed a bug in the implementation of tac. Please see also
https://github.com/uutils/coreutils/pull/4136
A short summary of changes:
* Add some basic tests for UChild and the run methods.
* Try more often in a fixed interval to create the tempfile for CapturedOutput.
* Fix drop order of struct fields for better cleanup of temporary files/dirs.
* Mark UChild::wait_with_output and UChild::pipe_in_and_wait_with_output deprecated
* Make CapturedOutput private
* Panic in stdout_all, stdout_all_bytes etc. if output is not captured.
* Rename some methods, refactor, clean up, fix documentation, add try_... methods
Add an `sprintf()` function (and `printf()` function) to
`uucore::memo`. The `sprintf()` function behaves roughly like the
standard Rust `format!()`, but follows our implementation of the GNU
`printf` formatting logic instead.
Before this commit, if `sparsefile` were a regular file of non-zero
size whose contents are all null bytes, then
dd if=sparsefile of=outfile conv=notrunc
would have resulted in `outfile` having zero size as reported by
`stat`. After this commit, `outfile` will have the same size as
`sparsefile` (even if the contents are represented sparsely by the
filesystem).
