* tail: reduce CPU load for polling
This reduces the CPU load for polling drastically (from ~80% down to ~5%)
by removing/fixing several previous workarounds related to polling,
while still passing all related GNU test-suite checks.
* set Notify::PollWatcher delay to: sleep_sec/10 instead of
sleep_sec/100
* set recv_timeout to sleep_sec instead of sleep_sec/100
* remove the manual polling of watched files
Bugs:
* fix an issue with headers to consistently pass
"test_follow_name_retry_headers" and "gnu/tests/tail-2/overlay-headers.sh"
Code clean-up and refactor
* make fields of struct FileHandling private (and add getters/setters)
to ensure that the paths are absolute and match the paths returned by
Notify::Events
* replace calls to "crash!" with "return USimpleError"
* clean-up formatting
When `--backup` is supplied, `cp` will take a backup of *destination* before *source* is copied. When `--backup=simple` is supplied, it is possible for the backup path for *destination* to equal the path for *source*, destroying source before the copy is made. This change prevents this by returning an error instead.
This fixes https://github.com/uutils/coreutils/issues/3629
Update `dd` to only print a concise form of the number of bytes with
an SI prefix (like "1 MB" or "2 GB") if the number is at least
1000. Similarly, only print the concise form with an IEC prefix (like
"1 MiB" or "2 GiB") if the number is at least 1024. For example,
$ head -c 999 /dev/zero | dd > /dev/null
1+1 records in
1+1 records out
999 bytes copied, 0.0 s, 999.0 KB/s
$ head -c 1000 /dev/zero | dd > /dev/null
1+1 records in
1+1 records out
1000 bytes (1000 B) copied, 0.0 s, 1000.0 KB/s
$ 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
Make `mktemp` exit with an error if the `--suffix` option is the empty
string and the template argument does not end in an "X". Previously,
the program succeeded.
Before this commit,
$ mktemp --suffix= aXXXb
apBEb
After this commit,
$ mktemp --suffix= aXXXb
mktemp: with --suffix, template 'aXXXb' must end in X
It is probably too hard to verify that the sync is actually performed,
so we just check that we have a test using the code path, pro forma.

Add a unit test for combining the directory given in `--tmpdir` with
any subdirectory structure appearing in the prefix of the template
string. For example,
$ mktemp --tmpdir=a b/cXXX
a/b/cNqJ
This behavior is currently working, but a unit test was missing.
Fix a bug in which `mktemp` would replace everything in the template
argument from the first 'X' to the last 'X' with random bytes, instead
of just replacing the last contiguous block of 'X's.
Before this commit,
$ mktemp XXX_XXX
2meCpfM
After this commit,
$ mktemp XXX_XXX
XXX_Rp5
This fixes test cases `suffix2f` and `suffix2d` in
`tests/misc/mktemp.pl` in the GNU coreutils test suite.
Simplify the logic of computing the file path parameters (the
directory, prefix, suffix, and number of random characters) for the
temporary file created by `mktemp`. This commits adds an `Options`
struct as a layer of indirection between the application logic and
`clap`, and a `Params` struct whose associated function is responsible
for determining the file path parameters from the `Options`. This is
an improvement because the previous code had some logic for
determining file path parameters in one place and some in another
place.
Show the "total" label in the "source" column or in the "target"
column if the "source" column is not visible.

Include the suffix in the error message produced by `mktemp` when
there are too few Xs in the template. Before this commit,
$ mktemp --suffix=X aXX
mktemp: too few X's in template 'aXX'
After this commit,
$ mktemp --suffix=X aXX
mktemp: too few X's in template 'aXXX'
This matches the behavior of GNU `mktemp`.
Correct the error message when the template argument contains a path
separator in its suffix. Before this commit:
$ mktemp aXXX/b
mktemp: too few X's in template 'b'
After this commit:
$ mktemp aXXX/b
mktemp: invalid suffix '/b', contains directory separator
This error message is more appropriate and matches the behavior of GNU
mktemp.
On macOS path.is_dir() can be false for directories
if it was a redirect, e.g. ` tail < DIR`
* fix some tests for macOS
Cleanup:
* fix clippy/spell-checker
* fix build for windows by refactoring stdin_is_pipe_or_fifo()
Correct the error message produced by `mktemp` when `--tmpdir` is
given and the template is an absolute path:
$ mktemp --tmpdir=a /XXX
mktemp: invalid template, '/XXX'; with --tmpdir, it may not be absolute
* add various tests adapted from `gnu/tests/tail-2/follow-stdin.sh`
* explicitly set_stdin to null where needed, otherwise stdin is always
`piped`
* tighten some existing tests (no_stderr, code_is, etc)
* add test for fifo
* add various tests adapted from `gnu/tests/tail-2/follow-stdin.sh`
* explicitly set_stdin to null where needed, otherwise stdin is always
`piped`
* tighten some existing tests (no_stderr, code_is, etc)
* add test for fifo
On Android and macOS all/some tests for stdin fail with:
`cannot stat '-': No such file or directory`
Apparently the `/dev/stdin` redirect workaround doesn't work for
these targets.
Update `chown` to allow setting the owner of a file to a numeric user
ID regardless of whether a corresponding username exists on the
system.
For example,
$ touch f && sudo chown 12345 f
succeeds even though there is no named user with ID 12345.
Fixes#3380.
Correct the error that arises from a path separator in the prefix
portion of a template argument provided to `mktemp`. Before this
commit, the error message was incorrect:
$ mktemp -t a/bXXX
mktemp: failed to create file via template 'a/bXXX': No such file or directory (os error 2) at path "/tmp/a/bege"
After this commit, the error message is correct:
$ mktemp -t a/bXXX
mktemp: invalid template, 'a/bXXX', contains directory separator
The code was failing to check for a path separator in the prefix
portion of the template.
* ensure that `fn run_no_wait` is only invoked if the system running the
test has `sudo` in $path
Previously, if run inside CICD, calling `fn run_ucmd_as_root`
would provoke `fn run_no_wait` to panic because there's no `sudo`.
When using left-justify with integer conversion (like `printf '%-o'`),
default the minimum width to 1.

Fix a bug in `mktemp` where it was not respecting the path given by
the positional argument. Previously, it would place the temporary file
whose name is induced by a given template in the `/tmp` directory,
like this:
$ mktemp XXX
/tmp/LJr
$ mktemp d/XXX
/tmp/d/IhS
After this commit, it respects the directory given in the template
argument:
$ mktemp XXX
LJr
$ mktemp d/XXX
d/IhS
Fixes#3440.
* Fix a timing related bug with polling (---disable-inotify) where some
Events weren't delivered fast enough by `Notify::PollWatcher` to pass all
of tests/tail-2/retry.sh and test_tail::{test_retry4, retry7}.
* uu_tail now reverts to polling automatically if inotify backend reports
too many open files (this mimics the behavior of GNU's tail).
