2019-07-19xargs: don't pretend to support -I.Elliott Hughes
This was embarrassing... A build script that was using xargs -I silently started to ignore -I when we switched over to toybox xargs. The owner of the script has rewritten it to use the shell read builtin instead, but it's pretty unhelpful to silently ignore an option that radically changes how xargs behaves. (The -I behavior sounds sufficiently different from normal behavior that I'm not sure I've understood, and am just sending this cleanup rather than actually implementing -I correctly.) Bug: http://b/137832162
2019-07-17ifconfig: fix for non-root on Android.Elliott Hughes
The change from ioctl to xioctl in 844f0d1aae28c54bbb672f53ba2cda182c572129 broke ifconfig for non-root on Android. SIOCGIFHWADDR has been protected to prevent device tracking since Nougat. Bug: https://issuetracker.google.com/137671590
2019-07-16Fix unaligned access, tweak test suite.Rob Landley
2019-07-16grep: fix two bugs found by hwasan.Elliott Hughes
The first bug appeared as a memory overwrite, but was actually visible without hwasan: basically any `grep -F` that let to multiple matches on the same line was broken. The second bug was another memory overwrite, visible when I ran the existing grep tests. Bug: http://b/137573082
2019-07-16ip.c route change support for extended attributes.Mike Bennett
This fixes the extended attribute settings for the ip route change command; extended attributes are collected in a separate buffer and added to the RTM message in a specific RTA_METRICS attribute. Only added setter support for the RTAX_MTU (per-route MTU), as that was the only option currently parsed. Also added support for displaying extended attributes, even those not currently settable.
2019-07-12diff: implement --strip-trailing-cr.Elliott Hughes
Used by some ART tests and also some LLVM tests. (The motivating example is the latter, but I noticed the former when looking for other users.) Bug: http://b/137298656
2019-07-12pidof: fix default behavior, add -x.Elliott Hughes
Before this patch, we're effectively doing `pidof -x` all the time. This patch changes names_to_pid() to allow us to say whether or not we want to include scripts, and adjusts the callers appropriately. Also add tests for `pidof` versus `pidof -x` which pass after this patch, without regressing the existing killall tests.
2019-07-12grep: add -R as well as -r.Elliott Hughes
On BSD these are actually the same, and there's a -S that you need in addition. So strictly this is a behavior change for Android (which is going from BSD grep to toybox grep), but it's a behavior preserving change for the AOSP build (which is going from GNU grep to toybox grep), and the latter actually has a checked-in use of -R where the former doesn't.
2019-07-11Next sh checkpoint. Not remotely load bearing yet.Rob Landley
2019-07-11bind/connect cleanup.Elliott Hughes
Rename the existing xbind/xconnect to xbindany/xconnectany, to make room for new xbind/xconnect that are more like 'x' versions of the regular bind and connect. Move explicit bind/connect callers over to xbind/xconnect. Of the affected commands, only netcat is actually used by Android. It was the most recent patch to netcat that made the lack of a more traditional xbind/xconnect apparent.
2019-07-11xargs: bug compatibility with BSD/busybox/findutils.Elliott Hughes
The other xargs implementations in the wild don't seem to count the space taken by each `char *`. Go for bug compatibility unless future experience proves that to be a bad idea.
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.
2019-07-09dd: fix seek= on stdout.Elliott Hughes
2019-07-06file: fix xz, add a few other Android types.Elliott Hughes
"xz compressed data" was missing a newline. Also switch a couple of other unnecessary (but correct) xprintf calls over to xputs. Also add .otf fonts, perf/simpleperf data files, and Android boot images, sparse images, and device tree blobs/overlays.
2019-07-06killall: better handling of long names.Elliott Hughes
Change names_to_pid() so that we can actually match shell scripts with long names (the code to get the shell script's name was correct, but there was an extra test preventing us from actually comparing it to the sought name). In kill.c itself, remove a dead test for -l and switch to the FLAG() macro. Also extend the tests to explicitly cover long and short names.
2019-07-06Add comment and test.Rob Landley
2019-07-06Have env exec, not recurse to builtin.Denys Nykula
My app runs npm i -S better-sqlite3, and node-gyp-bin from the npm upstream has #!/usr/bin/env sh, expecting the system shell.
2019-07-03nl: nl -vEric Molitor
Implement nl -v supporting negative and zero starting values.
2019-07-01netcat: Add UNIX domain socket support (-U)Tom Cherry
Other implementations of netcat support UNIX domain sockets via -U, so this change adds it to toybox too. Example usage: Create ./uds as a UNIX domain socket and listen on it, forwarding messages to bash: > nc -U -s ./uds -L /bin/bash Connect to ./uds as a UNIX domain socket > nc -U ./uds
2019-06-29More toysh flow control plumbing.Rob Landley
2019-06-28modinfo: various small fixes.Elliott Hughes
Improve Android support (see code comments). Remove unnecessary fixed-length limits. Show error if module not found (plus test). Expand help text. Switch to FLAG macro. Stop hard-coding module assumptions in the tests.
2019-06-28file, stat: various small improvements.Elliott Hughes
file now shows the target of a symbolic link and calls out broken symbolic links. file now shows the device type for block/character special files. file now shows specific reason when it can't open. stat now includes the device type, plus a little more space between the number of blocks and the human-readable file type. Adjusted tests accordingly, which actually makes more of them pass on the host as a convenient side-effect, but I actually made these changes because I've been finding the desktop file and stat output more convenient in these cases.
2019-06-26losetup: fix Android.Elliott Hughes
Use /dev/block/loop* more uniformly, and teach the tests which to expect.
2019-06-25Start over on toysh.Rob Landley
Basic line continuation logic (to prompt with $PS2). Doesn't use result yet.
2019-06-25losetup: minor fixes.Elliott Hughes
Fix `losetup -f` to not fail with an error. Add the missing \n for `losetup -f --show FILE`. Use decimal for the device number, like the desktop losetup. Switch to the FLAG macro. Make the tests runnable as tests, and expand coverage a bit. With this patch, the tests pass both with and without TEST_HOST on the desktop. Note though that this patch is part of fixing some real-life losetup issues, not part of the "test cleanup" I'm also looking at. losetup is low down that list!
2019-06-25tar: implement --mode.Elliott Hughes
Used by build/make/tools/mktarball.sh in AOSP. (Which is why today's switch to toybox tar got reverted.)
2019-06-24diff: fix diff of stdin for systems without /tmp.Elliott Hughes
xtempfile() alreay does the right thing, so switch to that. Also use xsendfile() for the actual copying. Fixes the cat tests on Android.
2019-06-23Switch cp.c to FLAG() macros.Rob Landley
2019-06-22Use FORCE_FLAGS in kill.c.Elliott Hughes
Otherwise kill flags don't work unless killall5 is also configured. Also switch to the FLAG() macro.
2019-06-22Fix mv with trailing slash in source.Denys Nykula
Press tab, have bash complete dir name with a slash, notice musl rename() dislikes that. Replace trailing slash in the cp loop with a null character, if the command name is mv. Add the slash back if an error occurs.
2019-06-21bc: fix a few bugs found in upstreamGavin Howard
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.
2019-06-19Avoid a double-definition (iphdr) from netinet/in.h and linux/ip_tunnel.h by ↵Mike Bennett
locally defining the single constant definition ip.c uses (IP_DF) if not already defined.
2019-06-12bc: fix previous patchGavin Howard
I put the check into the wrong if. That was my bad. Again.
2019-06-11bc: fix a bug in powerGavin Howard
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.
2019-06-11find: add -true/-false.Elliott Hughes
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.)
2019-06-10Improve signal name<->number conversions.Elliott Hughes
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.
2019-06-08macOS: numerous fixes.Elliott Hughes
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.)
2019-06-07Remove getprop, setprop, start, and stop from toyboxTom Cherry
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. Change-Id: Ic6022f1f506e10868c61f55d64fa4e7c1b14eba2
2019-06-07Implement stat %C and find %Z.Elliott Hughes
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).
2019-06-03Remove TAIL_SEEK config option, just always include it.Rob Landley
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.
2019-06-01Teach file to recognize xz archives and old style tarballs.Rob Landley
2019-06-01Teach tar to extract older tarballs.Rob Landley
2019-05-29Teach find -printf about %.Ns patterns, tweak help text, add tests.Rob Landley
2019-05-26Teach sed about +N range ending.Rob Landley
2019-05-25find: add -printf support.Elliott Hughes
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.
2019-05-25grep: add --exclude-dir.Elliott Hughes
Used quite a lot, especially with `--exclude-dir=.git`.
2019-05-25time: fix -v output.Elliott Hughes
Copy-and-paste mistake from the regular output. Bug: http://b/133502489
2019-05-25Move notify.c into portability.c (collate the #ifdefs), move global variablesRob Landley
into a structure passed as arguments, add x prefix to functions that can fail, add overflow test.
2019-05-25tail: support -f on BSD too.Elliott Hughes
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...
