2018-03-20Fix atolx not integer error when used with suffix *dMinghui Liu
2018-03-20Minghui Liu pointed out that the b and c suffixes were reported as errors.Rob Landley
2018-03-14Fix last uninitialized warning.Elliott Hughes
clang is fine with the noreturn nature of error_exit, but only if we don't `if (false)` it out for non-debug builds. lib/args.c:304:18: error: variable 'temp' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized] } else if (CFG_TOYBOX_FLOAT && new->type == '.') { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ external/toybox/generated/config.h:11:26: note: expanded from macro 'CFG_TOYBOX_FLOAT' ^ external/toybox/lib/args.c:308:19: note: uninitialized use occurs here options = --temp; ^~~~ external/toybox/lib/args.c:304:14: note: remove the 'if' if its condition is always true } else if (CFG_TOYBOX_FLOAT && new->type == '.') { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ external/toybox/lib/args.c:255:15: note: initialize the variable 'temp' to silence this warning char *temp; ^ = NULL
2018-03-12Fix bug in names_to_pid.Elliott Hughes
Found by the compiler, not me: lib/lib.c:1053:30: warning: 'st2.st_dev' may be used uninitialized in this function [-Wmaybe-uninitialized] if (st1.st_dev != st2.st_dev || st1.st_ino != st2.st_ino) continue; ~~~^~~~~~~
2018-03-10Split "comma separated values" parsing from mntent.h plumbing.Rob Landley
2018-03-10Add a way for commands to distinguish "ps -ax" from "ps ax".Rob Landley
2018-02-09Fix the pidof comm and cmdline tests.Elliott Hughes
If we have a 15-byte name, we don't know whether comm actually matches or is a truncated form of a longer name that has a common prefix. For example, with "this-is-a-very-long-name-that-is-too-long", we shouldn't match "this-is-a-very-" (but the old code would). The cmdline code was also broken on Android because it used basename(3) rather than getbasename. This doesn't affect glibc because there's a workaround in portability.h to ensure that we get the non-POSIX basename(3) with glibc but then a non-glibc section that ensures everyone else gets POSIX basename(3). That should probably be removed (and maybe `basename` poisoned) to prevent similar mistakes in future. Bug: http://b/73123244
2018-01-30Basic ping support.Rob Landley
Requires echo 0 $((1<<30)) > /proc/sys/net/ipv4/ping_group_range (as root)
2018-01-14Switch xgettty() -> tty_fd() (returning -1 instead of erroring out if none).Rob Landley
2018-01-06Move millitime() into lib.c.Rob Landley
2018-01-01Cleanup logger.c, and move the facilitynames/prioritynames SYSLOG_NAMESRob Landley
stuff syslog.h does into lib.c and portability.h
2018-01-01xphung on github said: "config2help currently doesn't work on OS X, itRob Landley
terminates parsing of Config.in at first blank line. This is because getdelim() in portability.c returns -1 whenever the line comprises only a single linefeed character. Fixing this was a trivial change to two lines (see below), and config2help now works on OS X but I haven't regression tested this on any other commands which rely on getdelim()"
2017-12-22Redo namestopid to handle more cases.Rob Landley
2017-12-19killall should kill scripts too.Elliott Hughes
Found running LTP file system tests on Android. Bug: http://b/70627145
2017-12-03Don't capitalize in the middle of a sentence.Elliott Hughes
Before: toy: Unknown option p (See "toy --help") After: toy: Unknown option p (see "toy --help")
2017-10-10Tweak help_exit() to show "See %s --help" message on the same line.Rob Landley
2017-10-10Complete rewrite of cut. Handle multipe ranges, add -DFO options, startRob Landley
of utf8 support (not finished yet)... Adds new loopfiles_lines() wrapper to lib.c that calls do_lines from loopfiles.
2017-10-01Fix xargs to obey POSIX's ARG_MAX restrictions.Elliott Hughes
This avoids "xargs: exec echo: Argument list too long" errors in practice. find(1) needs to be fixed too, but that's a bit more complicated and a working xargs provides a workaround. Bug: http://b/65818597 Test: find /proc | strace -f -e execve ./toybox xargs echo > /dev/null
2017-09-09Last commit used xstrtod(), forgot to check it in.Rob Landley
2017-09-05Tweak utf8towc() to return -1 earlier sometimes (instead of -2), and add testRob Landley
program to compare against libc output.
2017-09-02utf8towc() has to be in lib.c if strlower() is going to use it, becauseRob Landley
scripts/*.c builds against lib.c but not linestack.c.
2017-09-02In wc, replace mbrtowc() with new utf8towc() which doesn't have a context structRob Landley
or care about locale.
2017-07-17Split out xgetaddrinfo() from xconnect()Rob Landley
2017-07-11comma_scan()'s clean option wasn't removing entry at end of list.Rob Landley
2017-07-07Make dd use atolx_range(), and teach atolx_range() about "w" suffix (word, *2).Rob Landley
2017-06-26Most things seem to want the "b" suffix to mean 512 instead of 1.Rob Landley
(According to the git history I added "b" for "od" but the man page says 512 there too.)
2017-06-06Add comment explaining strend()Rob Landley
2017-06-05Have help_exit() give a brief "See %s --help" message instead of theRob Landley
full help text, and put it back in the args constraint failures.
2017-05-24Add and use xmmap.Elliott Hughes
Everyone forgets that mmap returns MAP_FAILED rather than NULL on failure. Every use of mmap in toybox was either doing the wrong check, or no check at all (including the two I personally added).
2017-05-23Add minof/maxof macros that autodetect type. Make xzcat use them.Rob Landley
2017-05-21Cleaup chrtRob Landley
2017-05-08Move strend() to lib/lib.cRob Landley
2017-05-08Remove old uClibc compatibility glue. It's been 5 years since the last release.Rob Landley
See http://lists.busybox.net/pipermail/buildroot/2016-December/180102.html for a full post-mortem on the project.
2017-04-30Android NDK doesn't have cutils/sched_policy.h so add a probed config symbol.Rob Landley
2017-03-23Now that just about everything has --help, don't output help for argument errorsRob Landley
2017-03-20Add TOYBOX_PEDANTIC_ARGS to check arguments when there are no arguments,Rob Landley
and make uptime use it.
2017-02-204a4b3d65644ce403b0f22887fc0d38b0202ec8c7 upset clang.Elliott Hughes
Recent-ish clang doesn't like self-assignment. Google/Android code always uses the [template-based moral equivalent of] __attribute__((__unused__)) to keep both compilers happy.
2017-02-20Fix dmesg -c and -C.Elliott Hughes
I never use these, so I didn't notice I'd broken them until someone who does bringup complained. The "one weird trick" with SEEK_DATA is documented at the URL we already point to. SEEK_DATA was added in Linux 3.1 (2011) and isn't available in glibc 2.19 (2014), so I've added that to "portability.h" for the benefit of Ubuntu 14.04. Also make -c and -C mutually exclusive. Also fix some of the formatting I introduced earlier. (A clang-format file would help prevent these mistakes...)
2017-02-05Don't set SIGWINCH when reading ANSI size probe data, it causes a loop.Rob Landley
2017-02-05Silence a warning.Rob Landley
Once upon a time you could call fchown() and let it fail. Then gcc decided not using its return code was inconcievable, but you could typecast it to (void) to shut it up. Then gcc noticed people doing that and clutched its pearls and took it away, so I added an if() statement that does nothing with the result because we _expect_ this to fail when we're not root. Then clang started complaining about an if (); statement with the semicolon on the same line, but decided it's ok if the ; is on the next line (I.E. significant whitespace in C), so I'm adding an "assignemnt to self" that gets optimized away so it does a more _explicit_ nothing (the same way you suppress gcc's broken "this isn't used uninitialized" warnings). If the compilers weren't going to so much trouble to force the issue I might add code to only call fchown when we're UID 0, but I refuse to be coerced into it. (And if getpid() is still a system call instead of a vdso member then it doesn't actually _save_ us anything, the dentry should be hot and the permission check was just "if (!uid)" before selinux entered into it and we're operating on an fd so the security's the same.)
2017-02-04Posix says stdio.h should define 'stdout' as a macro, and bionic turns it intoRob Landley
an array index, which doesn't work as a local variable name. So rename it.
2017-02-04Switch oneit to use xopen_stdio() for -c (oops) and switch XVFORK() to useRob Landley
__attribute__((returns_twice)) instead of noinline. Yes LLVM supports it: https://llvm.org/bugs/show_bug.cgi?id=6287
2017-01-28Fix padto in draw_trim_esc() so it behaves like printf %*.*s and matches theRob Landley
comment (I.E. negative first value _left_ justifies). This makes ps display the same truncated values with and without a tty. Also add a few comments to the rest of the file.
2017-01-04Some lib fixes: mark xvfork() noinline, make xsendfile() return bytes copied,Rob Landley
make xsocket()'s returned fd CLOEXEC.
2017-01-04An option can't exclude itself, so "abc[-ab][!abc]" with "command -a -b"Rob Landley
shouldn't segfault falling off the end of the list trying to report a nonexistent error condition.
2016-12-08Add DIRTREE_PROC to skip non-numeric entries and make ps/top etc use it.Rob Landley
2016-11-21Have dirtree_notdotdot() pass through !node->parent so . and .. on the commandRob Landley
line aren't filtered out. Audited all the callers and removed redundant calls, adjusted call sequence, etc. (And let rm _not_ do this, because posix.)
2016-10-20Allow out and escout to be NULL in crunch_str()Rob Landley
2016-10-11Make netcat work with nommu and factor out poll() loop into net/net.c.Rob Landley
2016-09-30sed -i run as root wasn't preserving ownership.Rob Landley
