macOS doesn't have real-time signals, and it has a slightly different
set of non-portable signals from Linux.
With this, the toybox `kill -l` output matches the default macOS kill(1).
|
|
This bug is that an error should be returned when the user tries to take
0 to a negative power, since that is undefined, but bc would return 0.
|
|
Used near the end of the AOSP build. Almost there!
(This patch also fiddles with the help text to be able to slip the new
options in without requiring so much extra space.)

(`kill -l HUP` and `kill -l 1` both said "HUP" instead of giving you
back the one you didn't provide, before my real-time signal patch.)

Gentoo packages that build multiple variants, like once for every
version of a slotted dependency, currently fail to install if their
source dir includes a relative symlink to own child. Affects lots of
Python infrastructure, for example meson and setuptools. You've already
run into this issue, since cp.test has a todo. It's from 2008 though, so
I guess I'll bump with an expanded test case. Libc is musl-1.1.22.

Include all the signals, not just the POSIX ones.
In particular, improve support for real-time signals. My attempt to
switch AOSP builds over to toybox timeout got reverted when I broke the
ART build bots which use SIGRTMIN+2.
Also fix `kill -l 3` to show "QUIT" and `kill -l QUIT` to show "3".
Also make the `kill -l` output include numbers and names, and format it
to look better on a 80x24 tty, because it's always August 1978 somewhere.

This patch adds a BSD version of xgetmountlist (for the path ==
NULL case only), tested on macOS. It also papers over the differences
between macOS' and Linux's xattr APIs. For once I think the macOS
one is better. The imitation of mknodat I've had to write swings
things back in Linux's favor though.
BSD calls f_frsize by the name f_iosize instead. (FWIW, it looks
like this is meaningless on Linux and actually meaningful on macOS.)
I've added one #if to toys/ --- I'm calling pathconf in stat.c to
work around the absence of f_namelen, and have left a TODO with an
explanation. I'm not sure what the best fix is here, so punting.
No-one can agree what f_fsid is, even if they're all basically the
same, so work around the `val` versus `__val` issue between macOS
and Linux.
With this patch, it's now possible to build cp/mv/install and stat
for macOS too. (Which completes the set of "toybox commands currently
used on Linux as part of the AOSP build" if you ignore stuff that
deals with processes, which I doubt we'll ever be able to support
for lack of any API.)

These are Android specific, so not really helping the outside
community, and are getting more and more Android dependencies to work
correctly, so let's drop these from toybox and build them within
Android.

We'd documented find %Z but not implemented it. We'd neither documented
nor implemented stat's corresponding %C (they'd already taken %Z for
ctime, which is ironic because %c/%C sounds more obvious than %z/%Z for
that to me).

Macs are slow enough without crippling them further!

Yeah, it's twice the size and two codepaths, but seekable is the common
case, it won't work in pipelines without a non-seek codepath, and the
performance penalty not using seek on large files is a enormous.
|
|
Trivial breakage from the recent refactoring.
Also add tail to the default config for macOS.
I'm still unconvinced that CONFIG_TAIL_SEEK makes sense in a world
where inotify support is always built in, but that's an argument
for another day...

(which doesn't handle "VAR=blah thingy" right if thingy is a function,
the variable winds up staying set after the function returns.)

This only implements the format specifiers that I've seen used in the
wild (which is actually a significant fraction of the total supported by
findutils' find). The most obvious gap is in the time support. I'm happy
to add more, but didn't want to add stuff "just because".
I'd say %A@, %C@, and -- for SELinux users -- %Z are probably the most
plausibly useful formats still missing. I don't think the human-readable
date formatting is particularly useful unless someone's seen it actually
used in the wild. The %T+ "full ISO" format being the most likely
exception to that.
Anyway, this is enough for me get started building AOSP with toybox find.

Used quite a lot, especially with `--exclude-dir=.git`.

Copy-and-paste mistake from the regular output.

into a structure passed as arguments, add x prefix to functions that can fail,
add overflow test.

Factor out the inotify code and add a kqueue equivalent.
Specifically tested on macOS 10.14, but I assume this works for other
BSDs too, given that I worked from the FreeBSD man page...

out of scope), but the AOSP build airlock doesn't provide bzcat and friends.
So tar needs to be able to use both: check for *zcat first, and fall back to
"compressor -d" if it's not there.
|

Found trying to build the aosp_cf_x86_phone-userdebug target. The good
news is that the targets that I knew were using tar with sparse files
all pass now.
|

Aside: I was surprised that `make defconfig` installs the default *Linux*
config even on macOS.

There's no possible use for this, but debian's tar produces it, so...
|
|
And fix tar cv to produce output to stderr when archive going to stdout.

and record Kirk McKusick's email for posterity. (I posted it to the
mailing list when it happened, but this is more obvious...)

Add test to show failure case.

Also, debian's lsattr is producing longer output lines with new fields,
possibly an ioctl switch from FS_IOC_GETFLAGS -> FS_IOC_FSGETXATTR? Anyway,
todo items here...
