The GNU tar manual, when talking about the `tar --transform` option that I
need to implement, describes the 'x' flag by saying "regexp is an extended
regular expression (see section 'Extended regular expressions' in GNU sed)".
Only it turns out that even the latest GNU sed doesn't actually have
that flag. It's unique to `tar --transform`. That link is just telling
you that the sed manual will explain extended regular expressions, not
that GNU sed also supports the 'x' flag.
So I don't know whether we want this in toybox sed after all. (It made
sense that sed would have such a flag, but no sed that I know of
actually does.)

Based loosely on the Plan9/Inferno utility, and a convenient way to go back
and forth between code points and utf8 sequences.
This patch also fixes a couple of bugs in wctoutf8 (and the tests for this
toy effectively serve as unit tests for wctoutf8/utf8towc).

The rest of `make tests` all pass on a Raspberry Pi 400.

The AOSP build doesn't use tr (or anything that's still in pending), but
the kernel folks have been more aggressive. They found that tr's
pathological flushing was adding minutes to their build times.
Just removing the fflush() made tr significantly faster for my trivial
test, but still slow, with all the time going into stdio. Rewriting the
loop to modify toybuf in place and then do one write per read made most
of the difference, but special-casing the "neither -d nor -s" case made
a measurable difference too on a Xeon.

Change 5109da9b3e6a898c8e0ad647303a1b375e3d97d3 caused test.test to call
chmod with mode `u+s+s` which passes on the host (where you have a
toybox test but a GNU chmod) but fails on Android where chmod is toybox
too.
Add the missing loop to string_to_mode(), which means this will also
affect other toys, but that seems like a feature (and, for example, GNU
mkdir also accepts a mode like `a=r+w+x`).

tests to catch this. While there add -k to test sticky bit.

I didn't know until implementing this that --iso is actually called
--iso-8601 and that GNU date will actually accept any prefix. --iso-8
works fine too. I've assumed that --iso (that I always used) and
--iso-8601 (as given in the documentation) are the only two that matter.

(The bug is that "echo hello \" followed by just enter should end the $PS2
state but it persists when the line is empty because resulting collated line
still ends with \ so it wants another line.)

f2fs with compression enabled only lets you `chattr +c` on an empty
file.

Debug wildcard * match, teach skipslash() to fill out a wildcard deck,
make collect_wildcards() flush remove the parsing-only 0th entry.

contexts like scripts, and tweak debug scaffolding.

This round trip occurs in practice with $KBUILD_BUILD_TIMESTAMP in
kernel builds.

GNU says "/dev/stdin" for the filename, but we say "-".
|
|
This also changes the other compression options (such as -j) so that we
pass no arguments for compression and just -d for decompression, which
is what -I does to its filter and which appears sufficient. (I think I
used -dc before just out of habit, since that's what I've been typing on
the command line for decades.)
|
|
Also, the failing mv test was because posix says to prompt when mv-ing over an
unwriteable file only when stdin is a tty (but -i prompts either way)
|
|
Also fix help text to say that it is not the default.
|

Allow -pd to work by changing -p from an option that takes an
argument to an option that implies there will be an argument (that
is, `-pd x` is `-p -d x` with x being the directory for -p, rather
than `-p d x` with d being the directory, as we previously interpreted
it).
Fix -d (aka --make-directories) to not be a no-op. Previously we
acted as if this was always on.
Accept --quiet and effectively just ignore it, since toybox cpio
doesn't seem to produce any output that --quiet would suppress.

Rob's code supports more formats than mine did, so add the extra tests.

Requested in https://github.com/landley/toybox/issues/130, quoting an
old version of the toybox help. This is also supported by coreutils.
Set $LANG to C in the date tests so that they pass with TEST_HOST=1
(they were already failing for me, presumably related to a newer glibc).

This is a follow-on from 310eefe, addressing the case where sscanf fails
and returns -1.

has a build script that goes much faster with it, and added tests for it.
I reimplemented it a different way, and did SIGUSR1 and SIGUSR2 support.

Fixes #227.

(Also fix -v output going to stderr when it shouldn't.)

This let me compare against the host for #225.

Found trying to run the libc++ tests.
For coreutils, `info chmod` says:
'chmod' ignores symbolic links encountered during recursive directory
traversals.

Includes removing a test that's just gratuitously checking whether or not
a corner case gratuitously differs from coreutils. (So what? Who cares?)
|
|
SKIP_HOST won't run a test when TEST_HOST set, but toyonly runs its arguments
whenever testing toybox (including when the host version is toybox).

slightly more elaborate debug output.
|
|
|
|
Point is to make sure the consumer waits for all output, not for process exit.
