2014-11-21Patch from Elliott Hughes for Android/bionic build.Rob Landley
2014-11-19Fixups for the android/bionic build probes patch.Rob Landley
The CFG_* symbols are always defined so if() can use them as compile-time constants, so don't if defined() them. Doing USE_BLAH() around variable definitions opens up the same potential for config-dependent build breaks as #ifdefs do, just make the whole command depend on the symbol for now, factor out the utmpx infrastructure later. The PTY probe was always failing because it used NULL without #including the header that defines it. Substitute 0 instead.
2014-11-19probe for getspnam(), forkpty(), utmpx, replace sethostname()Isaac Dunham
Android is missing all of these; we need to probe for some so we have a config symbol to depend on. sethostname() is easily replaced. We got termios.h via pty.h; now it's not included in configure-step tools, so we need termios.h to generate globals.
2014-10-02Workaround for musl's faccessat bug (the rm -r "error: is a directory" thing).0.5.0Rob Landley
The Linux man page says I can use AT_SYMLINK_NOFOLLOW. It works in glibc, uclibc, and klibc, but musl returns -EINVAL any time you pass in that flag and the maintainer says that's not a bug and insists the man page and those other libraries all change to match musl's behavior. Toybox uses it to avoid scheduling unnecessary metadata writes for things we're about to delete (have to chmod unreadable directories so we can descend into them to delete their contents, the chmod happens before we descend so the disk I/O has plenty of time to be scheduled) because the extra writes wear out SSD faster. It's just an optimization and I don't really care if it works _well_ (the fchmodat call _also_ takes AT_SYMLINK_NOFOLLOW so that's covered), but musl's behavior uniquely makes the check always error and thus breaks normal "rm -r". Yes this workaround is checking #ifdef __MUSL__ which the library does not supply (because its code is perfect and will thus never need to be worked around). You can CFLAGS=-D__MUSL__ if you don't echo "#define __MUSL__" >> include/features.h when installing the library.
2014-09-20Tweak portability.h for uClibc version in buildroot defconfig.Rob Landley
I've been locally patching uClibc to not violate posix-2008 (you don't need to define a GNU macro to get a posix function), but uClibc is obsolete and moribund (development peaked in 2006, last bugfix release was over 2 years ago), and the largest remaining user (buildroot) doesn't bother to apply such a patch. Since even buildroot is slowly migrating to musl-libc, just do the portability tweak for what the last release of the old thing actually did.

2014-08-12Patches to commands for issues reported from static analysis tool.Ashwini Sharma
portability.h.patch - it is for O_CLOEXEC, as compiler complained of it. Makefile.patch - for cleaning generated/*.o files and libopts.dat file [Fixup to uniq.c from Rob.]
2014-07-20Add utf8 support to ls -C.Rob Landley
Use wcwidth() instead of strlen(), and extend the -q substitution to also whiteout nonprintable characters that are nonparseable utf8 snippets.
2014-05-06Use compiler built-in macros to determine if argument parsing can use double ↵Rob Landley
or float for FLOAT arguments. (I.E. whether double fits in a long's memory.) Check in a way that the macros not being defined just gives us the shorter one.
2014-04-15Probes for O_NOFOLLOW that compile and run something aren't compatible with ↵Rob Landley
cross compiling, so just #define it to 0 if it's not in fcntl.h where posix-2008 says.
2014-03-29Group headers by standard (POSIX or LSB) or function (internationalization, ↵Rob Landley
networking). Move headers standards ignore (but which have been there >15 years) to lib/portability.h. Fold xregcomp into lib since it's posix.
2014-01-28Two changes to shut up GCC:Isaac Dunham
* __GLIBC__ was checked unconditionally; this made for a very messy build on musl. * int fd in chvt is always initialized; GCC 3.4 does not recognize this.

2013-02-04More support for old (~2008) build environments, move the #ifdef checks for ↵Rob Landley
symbols out of specific library version checks (shouldn't hurt anything), remove obsolete debug macro.
2013-01-15Work around more random uClibc-specific breakage.Rob Landley
2012-12-01Fix ancient glibc workaround to force fstatat64Rob Landley
2012-11-26The headers of uClibc and older glibc got unhappy with O_DIRECTORY and some ↵Rob Landley
other stuff. Fix it up in portability.h.
2012-11-16More touch cleanup to use generic infrastructure: use getdate() from libc, ↵Rob Landley
use flag macros, option parsing can collect argument strings in global block, use existing perror_* macros.
2012-11-13Older versions of glibc predated posix-2008. They still provide most of what ↵0.4.1Rob Landley
we need, but require a boot to the headers to get them to admit it. Note that uClibc lies and claims to be glibc so we have to specifically exclude it here.
2012-06-16More header fiddling: crypt.h is silly, SUSv4 requires crypt() to be ↵Rob Landley
prototyped in unistd.h. The fact glibc refuses to do so without a wacky #define is a glibc bug, treat it as such.

2007-01-18Add fdprintf(). Remove reread() and rewrite() which handle -EINTR, whichRob Landley
shouldn't be a problem if we register signal handlers with sigaction(SA_RESTART) Straighten out count and len (I generally consistently use "count" for the current progress and "len" for the total, but this time I got them backwards for some reason and don't want to confuse myself in future.)
