src/tools/regression/bin/sh/builtins, branch upstream/11.0.0

Migrate tools/regression/bin/ tests to the new layout.

2013-12-11T04:09:17Z

This change is a proof of concept on how to easily integrate existing tests from the tools/regression/ hierarchy into the /usr/tests/ test suite and on how to adapt them to the new layout for src. To achieve these goals, this change: - Moves tests from tools/regression/bin// to bin//tests/. - Renames the previous regress.sh files to legacy_test.sh. - Adds Makefiles to build and install the tests and all their supporting data files into /usr/tests/bin/. - Plugs the legacy_test test programs into the test suite using the new TAP backend for Kyua (appearing in 0.8) so that the code of the test programs does not have to change. - Registers the new directories in the BSD.test.dist mtree file.

sh: Properly quote alias output from command -v.

2013-11-10T23:00:39Z

An alias should be printed by command -v as a command line; therefore, make the alias definition suitable for re-input to the shell.

sh: Allow trapping SIGINT/SIGQUIT after ignore because of '&'.

If job control is not enabled, background jobs started with ... & ignore SIGINT and SIGQUIT so that they are not affected by such signals that are intended for the foreground job. However, this should not prevent reassigning a different action for these signals (as if the shell invocation inherited these signal actions from its parent). Austin group issue #751 Example: { trap - INT; exec sleep 10; } & wait A Ctrl+C should terminate the sleep command.

sh: Make return return from the closest function or dot script.

Formerly, return always returned from a function if it was called from a function, even if there was a closer dot script. This was for compatibility with the Bourne shell which only allowed returning from functions. Other modern shells and POSIX return from the function or the dot script, whichever is closest. Git 1.8.4's rebase --continue depends on the POSIX behaviour. Reported by: Christoph Mallon, avg

sh: Recognize "--" as end of options in type builtin.

2013-08-30T12:09:59Z

This implementation makes minimal changes: command names starting with "-" (other than "--") can still be queried normally.

sh: Recognize "--" as end of options in alias builtin.

2013-08-25T11:42:53Z

Aliases starting with "-" (which are non-POSIX) will need to be preceded by an alias not starting with "-" or the newly added "--".

sh: Recognize "--" as end of options in bg/fg/jobid builtins.

2013-08-16T13:56:43Z

sh: Add test for the non-standard jobid builtin.

2013-08-16T13:48:11Z

sh: Recognize "--" as end of options in local builtin.

2013-08-14T21:59:48Z

sh: Add tests for 'local -' (save shell options).
