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
2016-09-05Replace loopfiles' failok with WARN_ONLY open flag.Rob Landley
2016-09-05Export notstdio() wrapper.Rob Landley
2016-09-04Add openro() and WARN_ONLY flag so xopen() and friends can warn without exiting.Rob Landley
2016-09-04Switch help.c from #ifdef to if()Rob Landley
2016-09-03Move genericish function to lib.Rob Landley
2016-08-18Change xgetpwnamid/xgetgrnamid to xgetuid/xgetgid returning the id numberRob Landley
instead of a struct. This means it can return "12345" even if that user/group doesn't exist in /etc/passwd and similar. All the users were immediately dereferencing it to get pw_uid or gr_gid anyway, so just return it directly and adjust the users. This fixes things like "chown 12345:23456 filename".
2016-08-13Add TOYFLAG_NOHELP to disable --help processing for individual commands,Rob Landley
apply it to "true" and "false".
2016-08-13Move getusername/getgroupname to lib. (Return name or string representationRob Landley
of number, but never NULL. Both returned in static buffer good through next call.)
2016-08-04Make xopen() skip stdin/stdout/stderr, add xopen_stdio() if you want stdout,Rob Landley
add xopenro() that takes one argument and understands "-" means stdin, and switch over lots of users.
2016-08-02Fix warning: 'XATTR_NAME_SMACK' macro redefined.Elliott Hughes
Recent Linux uapi <linux/xattr.h> headers define XATTR_NAME_SMACK. The <sys/xattr.h> include at the top of lib/lsm.h means that even though the direct include of <linux/xattr.h> is guarded, it may have already happened transitively anyway. (The alternative fixes would be to hard-code the correct value for XATTR_NAME_SMACK here instead, or #undef XATTR_NAME_SMACK.)
2016-07-26Move regexec0 into lib (regexec that takes length and matches after NUL).Rob Landley
2016-07-15Don't close stdin when loopfiles reads "-".Rob Landley
2016-07-13Bugfix: suffixless string was feeding terminating NUL to strchr() and matching.Rob Landley
2016-07-12Convert atolx() and friends to use long long internally. Update design.htmlRob Landley
to use this (and tail) as examples of simplicity of implementation winning and losing.
2016-07-08dd improvements.Elliott Hughes
Support hex (requested by users). Support status=noxfer and status=none (requested by users). Fix status output. Clarify large numbers in --help output. Use O_TRUNC rather than ftruncate unless we're also seeking. New tests. Also partial cleanup (reuse of existing code, removal of non-GLOBALS globals, and merge dd_main and do_dd).
2016-07-04Now that we're using the adjusted option string, need to skip placeholders ↵Rob Landley
in [groups].
2016-06-30Use libbuf instead of stack buffer.Rob Landley
2016-06-19Last commit depends on new lib code I forgot to check in. (Oops.)Rob Landley
2016-06-15Add readlink0() and readlinkat0() which null terminate the data.Rob Landley
2016-05-25Stand alone builds of OLDTOY should show help text for corresponding NEWTOY.Rob Landley
2016-05-20Add bufgetgrgid()Rob Landley
2016-05-17Add bufgetpwuid. (Repeated calls to getpwuid() are really expensive.)Rob Landley
2016-05-04Simplify ps android scheduling policy fetch slightly.Rob Landley
2016-04-30Add a ps "PCY" field for Android scheduling policy.Elliott Hughes
2016-04-23Fix more to not append an extra newline.Elliott Hughes
More's sigatexit handler needs to distinguish between normal exit and exit due to receipt of a signal. Change tty_sigreset to look at the signal number too, so that pressing 'q' to exit top doesn't cause its exit status to be 128.
2016-04-21Have dirtree_recurse() take the new dirfd as an argument.Rob Landley
2016-04-16Fix "ssh top".Elliott Hughes
The ps.c change allows us to start. The interestingtimes.c change allows us to clean up properly afterwards if you ^C out (which you usually do). Tested with both ssh and "adb shell" (the latter being where I noticed the problem).
