* shell: Enable automake silent rulesAntonio Ospite2018-12-14
| | | | | | | | | | | | | Enable automake silent rules to make it easier to spot compilation problems. Silent rules will be enabled by default, but only if they are available, in order to keep compatibility with older autotools versions. Prepend the silent strings also to custom rules.

* shell: Update configure.ac with suggestions from autoupdateAntonio Ospite2018-12-14
| | | | | | | | | | | | | | Apply the changes suggested by running autoupdate on the source repository: 1. Properly quote AC_INIT arguments. 2. Use AC_USE_SYSTEM_EXTENSIONS instead of AC_GNU_SOURCE. The former is a superset of the latter, and enables more options, see https://www.gnu.org/software/autoconf/manual/autoconf-2.60/html_node/Posix-Variants.html Signed-off-by: Antonio Ospite <ao2@ao2.it> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* shell: Add subdir-objects to AM_INIT_AUTOMAKEJason Bowen2018-04-19
| | | | | | | | | | | | | | I've attached a patch which adds the subdir-objects option to AM_INIT_AUTOMAKE. For a while now when I've compiled dash I received a warning from automake that there are source files in a subdirectory but that the subdir-objects automake option was not supplied. I've just been adding it myself, but I finally got around to submitting a patch. The code still compiles for now (i'm using automake 1.15.1), but warning text is rarely nice to see and, if the warning text is to be believed, then the warning will eventually become an error.

* [BUILTIN] Fix "test -x" as root on FreeBSD 8Jonathan Nieder2014-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | POSIX.1-2008 §4.4 "File Access Permission" sayeth: If execute permission is requested, access shall be granted if execute permission is granted to at least one user by the file permission bits or by an alternate access control mechanism; otherwise, access shall be denied. For historical reasons, POSIX unfortunately also allows access() and faccessat() to return success for X_OK if the current process is privileged, even when the above condition is not fulfilled and actual execution would fail. On the affected platforms, "test -x <path>" as root started returning true on nonexecutable files when dash switched from its own emulation to the true faccessat in v0.5.7~54 (2010-04-02). Work around this by checking the permissions bits when mode == X_OK and geteuid() == 0 on such platforms. Unfortunately the behavior seems to vary from one kernel version to another, so we cannot just check the behavior at compile time and rely on that. A survey of some affected kernels: - NetBSD's kernel moved to the sane semantics in 1997 - OpenBSD's kernel made the same change in version 4.4, three years ago - FreeBSD 9's kernel fixes this but hasn't been released yet It seems safe to only apply the workaround on systems using the FreeBSD kernel for now, and to push for standardization on the expected access()/faccessat() semantics so we can drop the workaround altogether in a few years. To try it on other platforms, use "./configure --enable-test-workaround".

* [ARITH] Avoid imaxdiv when only one of the results is wantedHarald van Dijk2011-08-17
| | | | | | | | | | | | dash rather pointlessly calls imaxdiv, only to discard one of its results. The call was already made conditional a while back because some systems don't have imaxdiv, but the generated code for the version with imaxdiv and the one with / and % is identical (with GCC 4.6.1 or ICC 12.0.2, with -O0, -O2 or -Os), so it could just as well go entirely to clean up the code a little bit.

* [SHELL] Port to SolarisBrian Koropoff2011-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Solaris lacks paths.h and the various _PATH_* #defines. Check for them in configure.ac and fall back on the usual suspects when they are missing. - Older Solaris lacks isblank(), and versions that have it use a macro. Check for the declaration in configure.ac and fall back on a naive version when missing. - Older Solaris does not support %jd (intmax_t) in format strings, but it does support the PRIdMAX macro from inttypes.h. Do a configure check for PRIdMAX and use it in the code. If it doesn't exist, define it to "lld" when sizeof(long long) equals sizeof(intmax_t) as this is more likely to work on older systems. Otherwise, use "jd" and hope for the best. - Older Solaris lacks stdint.h, but inttypes.h provides the same types and works on all platforms I've tried dash on, so just use it instead. - Older Solaris doesn't like it when vsnprintf() is passed a NULL buffer (in violation of the POSIX spec, of course). Pass a 1-byte dummy buffer instead. - Solaris lacks tempfile and mktemp programs. Fall back on a "good-enough" custom function in mkbuiltins.

* [BUILTIN] Use faccessat if availableHerbert Xu2010-04-02
| | | | | | | | | | | | Eric Blake suggested that we should use faccessat so that ACLs and other corner cases are handled correctly. This patch does exactly that. Note that faccessat doesn't handle ACLs when euid != uid, as this case is currently implemented by glibc instead of the kernel, using code similar to the existing dash test.

* [BUILD] Fixed build on OS XMark Mentovai2009-01-13
| | | | | | | | | | | | | | | | | | | | Hi, Herbert and friends. I've created a small patch that allows dash to be built on Mac OS X. I'm contributing it here with the hope that it's suitable for inclusion in dash. The changes in this patch are: - __attribute__((__alias__())) is not supported, add an autoconf check - open64 is not present although the stat64 family is, separate the autoconf checks - A syntax error had slipped into a non-glibc codepath - mkbuiltins had a nonportable mktemp invocation for the case where tempfile is not availalble Nothing in this patch is actually Mac OS X-specific, so it might aid portability to other platforms as well.

* [BUILD] Fixed build on NetBSDAleksey Cheusov2009-01-13
| | | | | | | | | | Hi, I propose to apply the following patch for dash. The problem is alloca.h is absent on many platforms including NetBSD I'm running. Also, NetBSD's version of mktemp doesn't work without temporary filename pattern. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [EXPAND] Added configure --enable-glob and --enable-fnmatch optionsHerbert Xu2007-10-20
| | | | | | | | Debian's libc6 as of 2.6.1-6 has working glob(3)/fnmatch(3) support. This patch adds the options --enable-glob and --enable-fnmatch to the configure script. By default glob(3) and fnmatch(3) are still unused. However, on distros where the glibc is known to work you may enable these options.

* [SYSTEM] Added out-of-line ctypes functions for klibcHerbert Xu2005-10-29
| | | | | Unfortunately klibc doesn't provide out-of-line versions of ctypes functions such as isalpha. This is a nasty hack to create them.
* [SYSTEM] Added dummy sysconf implementationHerbert Xu2005-10-29
| | | | Add a dummy sysconf implementation that always fails for klibc.
* [SYSTEM] Added dummy strtod implementationHerbert Xu2005-10-29
| | | | | klibc doesn't have strtod or atof. So add an implementation that always fails by setting the end pointer to the input string.
* [BUILTIN] Disable ulimit if there is no getrlimitHerbert Xu2005-10-29
| | | | | | | | | | 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.
* [SIGNAL] Added default implementation of killpgHerbert Xu2005-10-29
| | | | | klibc doesn't have killpg. Since we only call it for valid values of pid, we can call kill instead.
* [SIGNAL] Added default implementation of strsignalHerbert Xu2005-10-29
| | | | klibc doesn't have strsignal but it does have sys_siglist.
* [EXPAND] Added getpwhome as a wrapper for getpwnamHerbert Xu2005-10-29
| | | | | klibc doesn't have and doesn't need getpwnam. This change creates getpwhome which always returns NULL if getpwnam doesn't exist.
* [SYSTEM] Added default implementation of bsearchHerbert Xu2005-10-29
| | | | Added impelmentation of bsearch since klibc doesn't have it yet.
* Use stat if stat64 does not existHerbert Xu2005-10-29
| | | | | | | | | 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.
* [SIGNAL] Use bsd_signal if it exists and signal does notHerbert Xu2005-10-29
| | | | | | | | 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.
* Copyright/licence updates and remove all traces of sys/cdefs.hHerbert Xu2005-10-29
| | | | | | | | | | | 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.
