producing (( (when the cmd starts with a '(' as that as a reserved
sequence (according to posix) and some shells do treat it specially.
So, force a space after the enclosing '(' to avoid the problem.
For symmetry, put a space before the concluding ')' as well, though
there is nothing special about )). (from kre@)
use printf %s instead of echo, as there are embedded \ chars in
some of the strings, and some other (nameless) shells insist on
treating \ in the args to echo as something special... (from kre@)
that could be interpreted as something different. That is, for our
shell +4++3 is just (+4)+(+3) and works fine. But others treat ++
as the increment operator. Same for --. Sprinkle spaces to taste.
(from kre@)
to wait for the same process over and over again (forever) (???)
This test now takes slightly over 20 seconds to complete (elapsed
time) caused by all the waiting on sleep commands being run in
the background. (from kre@)
work, now anyway) rather than working around a defect by using
/bin/kill (if the shell is broken, the test should fail, not succeed)
and test more aspects of the wait builtin in the kill test. (from kre)
that is not required by the standard. The test now allows either
of the two allowed responses. Also add commentary correcting
erroneous comments about what is correct, and incorrect. (from kre)
to the name of a shell, plus options that shell needs to run it
in the correct mode to be tested: eg: TEST_SH='bash -o posix'
Also finished the implementation of tests of "set -n" now that
the NetBSD shell supports that as it should. (from kre)
inside dot commands:
The test cases are named with the pattern
dotscope_cmd_cmdscope,
where dotscope is the scope in which the dot command is and cmdscope
is the scope where cmd is in the sourced file.
sh +nounset and `for X; do` iteration fails if parameter set empty
by applying and testing FreeBSD's patch of Oct 24 2009 for this; see
http://svnweb.freebsd.org/base/head/bin/sh/expand.c?r1=198453&r2=198454
Also created an ATF test in tests/bin/sh/t_expand.sh for this error and
corrected a space->tabs problem there as well.
