2005-11-14[BUILTIN] Fix \c spillage across echo commandsHerbert Xu

See attached patch for a > fix. Instead of setting rval when \c is detected, this is now set in the return value of conv_escape_str. This prevents the spillage reported in http://bugs.debian.org/337294.
2005-11-13[BUILTIN] Always call conv_escape_str in echocmdHerbert Xu
Instead of calling conv_escape_str when we detect a backslash we will call it unconditionally. This helps get rid of some unnecessary code in echocmd.
2005-11-13[MEMALLOC] Remove unnecessary truncation in _STPUTCHerbert Xu
Using char in the function argument causes unnecessary truncation to occur. This patch changes it to an int.
2005-11-04[HELPER] Use mktemp if tempfile is not availableHerbert Xu
tempfile(1) is Debian-specific so let's use mktemp(1) as a fallback.
2005-10-30[JOBS] Fixed support for disabling job controlHerbert Xu
Since nobody has compiled with JOBS turned off for quite a while, it has bit-rotted. This patch makes it build again.
2005-10-29[SYSTEM] Fixed fallback stpcpy implementationHerbert Xu
The implementation has an off-by-one bug. This results in random memory corruption. In one particular case, it caused certain bits of a function body to go missing.
2005-10-29[SYSTEM] Added out-of-line ctypes functions for klibcHerbert Xu
Unfortunately klibc doesn't provide out-of-line versions of ctypes functions such as isalpha. This is a nasty hack to create them.
2005-10-29[SYSTEM] Include system.h for stpcpy in nodes.cHerbert Xu
Since we have a fallback implementation for stpcpy we can now use it unconditionally in nodes.c.pat. This also fixes a link error with klibc.
2005-10-29[SYSTEM] Added dummy sysconf implementationHerbert Xu
Add a dummy sysconf implementation that always fails for klibc.
2005-10-29[BUILTIN] Removed standalone/csh support from testHerbert Xu
Let's remove the support for standalone support from test for the same reason as printf.
2005-10-29[SYSTEM] Added dummy strtod implementationHerbert Xu
klibc doesn't have strtod or atof. So add an implementation that always fails by setting the end pointer to the input string.
2005-10-29[BUILTIN] Removed standalone/csh support from printfHerbert Xu
The support for standalone/csh printf only serves to complicate maintainence.
2005-10-29[SYSTEM] Added default definition for SSIZE_MAXHerbert Xu
klibc doesn't define the macro SSIZE_MAX.
2005-10-29[BUILTIN] Disable histcmd completely when SMALL is definedHerbert Xu
Now that mkbuiltins correctly disabled histcmd we don't need the dummy histcmd implementation anymore.
2005-10-29[BUILTIN] Disable ulimit if there is no getrlimitHerbert Xu
For systems without getrlimit (e.g., klibc) we will disable ulimit. In order to achieve this, builtins.def is now produced by cpp which allows us to use macros such as HAVE_GETRLIMIT in it. Thie also means that we can get rid of the cflags parsing code in mkbuiltins.
2005-10-29[SIGNAL] Added default implementation of killpgHerbert Xu
klibc doesn't have killpg. Since we only call it for valid values of pid, we can call kill instead.
2005-10-29[SIGNAL] Added default implementation of strsignalHerbert Xu
klibc doesn't have strsignal but it does have sys_siglist.
2005-10-29Added missing system.h inclusion for mempcpyHerbert Xu
All users of mempcpy must include system.h.
2005-10-29Fixed gcc 4.0 compilation problemsHerbert Xu
Removed obsolete extern declaration on funcnest. This conflits with the correct static definition. Changed memtodest prototype to use char * instead of unsigned char *. Perform the unsigned char cast inside memtodest instead.
2005-10-29[EXPAND] Added getpwhome as a wrapper for getpwnamHerbert Xu
klibc doesn't have and doesn't need getpwnam. This change creates getpwhome which always returns NULL if getpwnam doesn't exist.
2005-10-29[SYSTEM] Added default implementation of bsearchHerbert Xu
Added impelmentation of bsearch since klibc doesn't have it yet.
2005-10-29Use stat if stat64 does not existHerbert Xu
64-bit file calls such as stat64 don't exist on all architectures for dietlibc, and they don't exist at all for klibc. In those cases the normal calls such as stat are already 64-bit. So simply define stat64 as stat if it doesn't exist. Do the same for all other 64-bit calls as well.
2005-10-29[BUILTIN] Stop using sysexits.h in commandcmdHerbert Xu
This gets rid of the only reference of sysexits.h in dash which is from commandcmd. This is needed for klibc support since it doesn't have sysexits.h. The only uses of sysexits.h in commandcmd is superfluous anyway. In fact, it is overly sensitive about usages such as 'command -vV ls'. By making its behaviour close to that of bash/ksh, we end up saving a bit of space too.
2005-10-29[SIGNAL] Use bsd_signal if it exists and signal does notHerbert Xu
klibc has bsd_signal instead of signal. So we will define signal as bsd_signal if 1) signal does not exist. 2) bsd_signal exists.
2005-10-29[SIGNAL] Removed use of __P from error.hHerbert Xu
This is the only instance of __P in the entire source so it makes sense to get rid of it rather than making it work with klibc.
2005-10-29Copyright/licence updates and remove all traces of sys/cdefs.hHerbert Xu
This change updates the BSD licence to the three-clause version since NetBSD has already done so. This makes dash GPL-compatible. It also adds Christos Zoulas (NetBSD ash maintainer) to the COPYING file. I've added "copyright by Herbert Xu" to most files. Finally all CVS IDs and inclusion of sys/cdefs.h have been removed. The latter is needed for support of klibc.
2005-10-26[INPUT] Size optimisations in preadbuffer()Herbert Xu
Added unlikely markers. Reduced switch coverage. Removed p since we now erase NULs as soon as we see them. Use more to store parselleft.
2005-10-01[INPUT] Fix NUL skipping in preadbufferHerbert Xu

This hurts if there are a lot of NUL characters, but should be a win in normal situations.
