Plus new tests.

Very few places actually check for errors from emit, and I actually see
the same endless loop from "sed (GNU sed) 4.4" on current Debian, so I'm
not sure this isn't Broken As Designed, but an endless loop spewing
"short write" (or saying nothing, in the case of GNU sed) really doesn't
feel like useful behavior in face of EPIPE, which really isn't going to
fix itself. Certainly not being able to run the sed tests to completion
is pretty annoying --- which is why, unless we remove this test as
invalid, we should probably also add a SKIP_HOST=1 to the "b loop" test.
Note that even with this fix you'll see the error twice:
sed: short write: Broken pipe
sed: short write: Broken pipe
Once from the first = command to fail, and then another from the !FLAG(n)
flush of the pattern space.

The test for \N where N was larger than the number of capturing groups
in the regular expression was incorrect, and firing for cases such as
matching __(ARM_)?NR_([a-z]*) against __NR_read, where the first group is
empty (because it failed to match) but the second group did match "read".
Use regex_t's re_nsub for the error check, and treat rm_so == -1 as a
signal to just copy nothing into the result.
(Found trying to build minijail in AOSP.)

Add support for more input formats, primarily the ISO formats used by
the AOSP build.
I've improved/added to the tests a bit to cover these changes, and to
explain the reasons for the various remaining test failures (none of
which are regressions caused by this patch).

Bug: http://b/123902291
|
|
Also add a TODO for the (undocumented, half-finished) -a option.

into display function, use unsigned length so output lines can be up to 4g each.
|
|
I accidentally added a tab in xargs.c, so as penance I'll clean up all
the tabs.
|
|
If table grows >64 entries XX needs to change, but it can't be 128 yet
because the slot value is a signed char. Currently 59 entries in table...
|
|
Implement -p, -t, and -r.
Add some missing tests.
Move -L and -x back to TODO since they're not implemented and I haven't
yet even understood what they're supposed to do.

Patch dates are optional these days, and I should properly work back from the
end and only peel off properly formatted tab+date, but "tab followed by
digit" is probably good enough and nobody's ever complained about just tab.
And we still don't support patching filenames with newlines in them...)

Used to construct SELinux policies in the AOSP build.
I left loopfiles_lines with its hard-coded '\n' because although cut(1)
also has a -z option, I can't find any case where it's used in any of
the codebases searchable by me. (And fmt(1), the other user, doesn't
even have the option.) YAGNI.

For a definition of "fix" that's even _more_ of a deviation from posix, but
matches what debian does...
|
|
Used by AOSP build.
Also switch to new FLAG macro.

It's in the Linux 4.20 kernel headers.

Handling -e by gluing together multiple regexes with | wasn't portable,
break down and do a linked list with for loops.

When necessary, realloc() the line to add 4 aligned bytes of storage at
the end, stick the unsigned offset in there, and then fish it back out for
display (and add 1 because offset is 0 based and display is 1 based).

Several parameters common on Linux are missing on macOS.

Be consistent about upper versus lower case. (Upper seems to have the
majority, so I went with that, though I'm happy to provide the opposite
patch as long as we're consistent!)
Be consistent about using \t. (Though saving a few bytes seems like it
might be better done in the code that generates help.h rather than
directly in the source, since tabs make careful ASCII art layout hard
enough that we regularly have things misaligned.)
Remove trailing periods (most of which seem to have been added by me).
Always use the US "human readable" rather than my British
"human-readable", and be more consistent about declaring whether we're
showing multiples of 1000 or 1024.
Just say "verbose" rather than adding a useless "mode" or "output".

Don't hard-code Linux's buffer size.
|

Even if we don't build ps, we can't have a Linux-only struct in GLOBALS.
The obvious alternative to this would be to have a fake struct sysinfo
in lib/portability.h. Since having a real macOS replacement for
sysinfo(2) seems unlikely at this point, I went this route instead.

bionic, glibc, macOS, and musl all have strcasestr
(see http://man7.org/linux/man-pages/man3/strstr.3.html).
macOS (via BSD) has a strnstr that does what strnstr sounds like it
should do by analogy with strnlen and strncpy.
So we at least need to rename strnstr, but it probably makes more sense
just to switch to strcasestr instead.

Used by OTA package scripts in AOSP, and quite widely inside Google.
I've also added --lines because it seems crazy to support one and not
the other, and --lines is also widly used inside Google too.
|
|
There are a bunch of if (!memcmp(s+28,...)) lines,
let's make them "else if"
|
|
I actually only need --quiet to build AOSP, but it seems weird to add
--quiet as a synonym for -s but _not_ add the more obviously related
--silent.
