* [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.

* [BUILTIN] Made t_lex reentrantHerbert Xu2008-07-13
| | | | | | | The previous two changes were broken because t_lex uses global state. This patch removes that by making t_wp local to t_lex. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [BUILTIN] Made aexpr/oexpr non-recursiveHerbert Xu2008-07-13
| | | | | | | Making these functions non-recursive is straightforward since they carry no state. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [BUILTIN] Fixed 3,4-argument cases for test per POSIXHerbert Xu2008-07-13

I see, you're right. Thanks, Gerrit. ----- End forwarded message ----- This patch hard-codes the 3,4-argument cases in the way required by POSIX.

* [BUILTIN] Use intmax_t arithmetic in testHerbert Xu2007-10-06
| | | | | This patch adds the function atomax10 and uses it in test(1) so that we support intmax_t comparisons.

| | | | | Check getgroups() and fwrite() return code, required to build with -D_FORTIFY_SOURCE=2.
* [BUILTIN] Removed standalone/csh support from testHerbert Xu2005-10-29
| | | | | Let's remove the support for standalone support from test for the same reason as printf.
* 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.
