2020-01-24cp/mv: add -T.Elliott Hughes
The kernel script scripts/kconfig/merge_config.sh uses cp -T. (Also sort the options into alphabetical order while adding -T, so that eyeball binary search actually works when trying to find an option! Oddly, they all show in reverse order because there's a bug in the help text generator, but that's a problem for another day...)

2019-07-10dd: iflags, oflags, fix ^C, fix the fundamental loop.Elliott Hughes
Investigating why the toybox tar tests fail on Android with toybox dd, I realized I was rewriting a part of dd I'd rewritten before! This is a re-send of my 2019-02-22 patch, rebased against the current ToT... This patch was originally motivated because after suggesting to the author of https://stackoverflow.com/questions/17157820/access-vdsolinux/54797221#54797221 that he could tell dd to work in bytes rather than blocks, I realized that our dd doesn't actually support that. But the rewrite of the main loop is necessary to fix the incorrect output from the dd calls in the tar test. Without this patch, `yes | dd bs=65536 count=1 > fweep` basically gives random output, based on how many bytes the pipe feels like giving you in your first read. (As far as I know, dd *without* bs= was fine, but I can't guarantee that that's true, just that I haven't seen it fail.) Also switch to TAGGED_ARRAY and comma_* for conv rather than add two more copies of an undesired idiom. It turned out -- contrary to the belief of cp(1) -- that comma_scan isn't suitable for this because of its magic handling of "no" prefixes. (It's actually harmless in cp because none of the --preserve options begin with "no", but some dd options do.) To this end, comma_remove is a less-magic comma_scan. I've also changed an `if` to a `while` because other implementations allow things like `--preserve=mode,mode` or `conv=sync,sync`. (If we decide this is a bug rather than a feature, we should at least fix the error message to be clear that we're rejecting the *duplication*, not the option itself.) I've also fixed the ^C behavior by simply adding a direct SIGINT handler rather than trying to be clever inside the read loop (which is why we weren't handling the SIGINT until the read returned). I've also removed `strstarteq` and just added the '=' to each literal when calling regular `strstart`. Plus basic tests.
2019-06-26Fix cp.test to pass even if you're root or have a restrictive umask.Elliott Hughes
2019-06-21Fix cp -r dir/. symlink child.makepost
Remove the existing link before trying to re-create, passing the test. Add -p to the -r test as a regression guard, portage calls cp with both.
2019-06-10Add failing test for cp -r dir/. symlink child.makepost
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.
