src/tools/regression/lib/libc/gen, branch main

Integrate tools/regression/lib/libc/gen into the FreeBSD test suite

2015-11-09T06:24:11+00:00

as lib/libc/tests/gen

The code in test-fnmatch that was used for generating:

- bin/sh/tests/builtins/case2.0
- bin/sh/tests/builtins/case3.0

has been left undisturbed. The target `make sh-tests` has been moved over
from tools/regression/lib/libc/gen/Makefile to
lib/libc/tests/gen/Makefile and made into a PHONY target

case2.0 and case3.0 test input generation isn't being done automatically.
This needs additional discussion.

wordexp(): Improve some error codes.

2015-08-19T20:31:03+00:00

Distinguish between WRDE_BADVAL and WRDE_SYNTAX based on when the error
occurred (parsing or execution), not based on whether WRDE_UNDEF was passed.

Also, return WRDE_NOSPACE for a few more unexpected results from sh.

wordexp(): Add testcase for non-default IFS in environment.

2015-03-29T22:00:24+00:00

The non-default IFS is expected to be used.

fnmatch(): Add test for r254091 (pattern with single backslash).

2013-08-11T21:54:20+00:00

This test cannot be converted to an sh(1) test because the syntax would be
invalid.

popen(): Add 'e' mode character to set close-on-exec on the new fd.

2013-05-20T17:31:18+00:00

If 'e' is used, the kernel must support the recently added pipe2() system
call.

The use of pipe2() with O_CLOEXEC also fixes race conditions between
concurrent popen() calls from different threads, even if the close-on-exec
flag on the fd of the returned FILE is later cleared (because popen() closes
all file descriptors from earlier popen() calls in the child process).
Therefore, this approach should be used in all cases when pipe2() can be
assumed present.

The old version of popen() rejects "re" and "we" but treats "r+e" like "r+".
