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.
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
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).
Move some tests that simulate a slow reader from `dd.rs` to
`tests/by-util/test_dd.rs`, and employ a FIFO and `sleep()` to
simulate the slow reader instead of a custom struct that implements
`Read`. This change restricts the type of `Input`s the
`Output::dd_out()` function can accept, facilitating a future change
to make `Input` an enum.
Allow uppercase "B" on its own as a unit specifier for the `count`,
`seek`, and `skip` arguments to `dd`.
For example,
$ printf "abcdef" | dd count=3B status=none
abc
Correct the behavior of `cp --reflink=never --sparse=always` so that
it performs a sparse copy. Before this commit, it was incorrectly
performing a dense copy.
Implement the `--copy-contents` option when the source is a FIFO, so
that the contents of the FIFO are copied (when the bytes become
available for reading) instead of the FIFO object itself. For example,
$ mkfifo fifo
$ cp --copy-contents fifo outfile &
[1] 1614080
$ echo foo > fifo
$ cat outfile
foo
[1]+ Done cp --copy-contents fifo outfile
Fix the behavior of `cp` when both `--backup` and `--force` are
specified and the source and destination are the same file. Before
this commit, `cp` terminated without copying and without making a
backup. After this commit, the copy is made and the backup file is
made. For example,
$ touch f
$ cp --force --backup f f
results in a backup file `f~` being created.
If the arg starts with an id numeric value, the group isn't set but the separator is provided,
we should fail with an error
Should fix tests/chown/separator.sh
Change `cp` to terminate with an error when attempting to copy through
a dangling symbolic link with the `--force` option. Before this
commit,
touch src
ln -s no-such-file dest
cp -f src dest
would incorrectly replace `dest` with the contents of `src`. After
this commit, it correctly fails with the error message
cp: not writing through dangling symlink 'dest'
Fix a bug where `cp` failed to copy ancestor directories when using
the `--parents` option. For example, before this commit:
$ mkdir -p a/b/c d
$ cp --parents a/b/c d
$ find d
d
d/c
After this commit
$ mkdir -p a/b/c d
$ cp --parents a/b/c d
$ find d
d
d/a
d/a/b
d/a/b/c
This commit also adds the correct messages for `--verbose` mode:
$ cp -r --parents --verbose a/b/c d
a -> d/a
a/b -> d/a/b
'a/b/c' -> 'd/a/b/c'
Fixes#3332.
Implement distributing lines of a file in a round-robin manner to a
specified number of chunks. For example,
$ (seq 1 10 | split -n r/3) && head -v xa[abc]
==> xaa <==
1
4
7
10
==> xab <==
2
5
8
==> xac <==

Before, the sort could work faster and we could be late with
the signal.
Now we create a new big file, `sort` can't process it in a minute,
so we can safely wait for the temporary directory to be created
and send a signal afterwards
Before the change it slept for 0.1 seconds and right after that
asserted if `sort` has created the directory. Sometimes `sort`
didn't manage to create the directory in 0.1 seconds.
So the change is it tries to wait for `timeout` starting with
0.1 seconds, and if directory was not found, it tries 4 more times,
each time increasing timeout twice. Once the directory is found
it breaks.
Make cp preserve the permissions of a directory when copying
it. Before this commit,
cp -pR src/ dest/
failed to copy the permissions of `src/` to `dest/`. After this
commit, the permissions are correctly copied.
While the rust coreutils semantics were arguably more correct,
they were different than the gnu split semantics when handling a
file without a trailing EOF. This patch addresses that difference
and allows passing one more GNU test suite.
Correct the error message produced when attempting to copy a directory
into itself with `cp`. Before this commit, the error message was
$ cp -R d d
cp: cannot copy a directory, 'd', into itself, 'd'
After this commit, the error message is
$ cp -R d d
cp: cannot copy a directory, 'd', into itself, 'd/d'
Allow `cp --remove-destination` to remove a symbolic link loop (or a
symbolic link that initiates a chain of too many symbolic
links). Before this commit, if `loop` were a symbolic link to itself,
then
cp --remove-destination file loop
would fail with an error message. After this commit, it succeeds. This
matches the behaviotr of GNU cp.
Generating the tests to run in build.rs created problems for tooling. For example, cargo fmt, was ignoring the test_*.rs files and needed to be passed these files manually to be formatted. Now we simply use the feature mechanism to decide which tests to run.
