ash,hush: tab completion of functions and aliases

2023-04-16T15:15:05+00:00

Since commit 9e2a5668f (ash,hush: allow builtins to be tab-completed, closes 7532) ash and hush have supported tab completion of builtins. Other shells, bash and ksh for example, also support tab completion of functions and aliases. Add such support to ash and hush. function old new delta ash_command_name - 92 +92 hush_command_name - 63 +63 ash_builtin_name 17 - -17 hush_builtin_name 38 - -38 ------------------------------------------------------------------------------ (add/remove: 2/2 grow/shrink: 0/0 up/down: 169/-55) Total: 100 bytes Signed-off-by: Ron Yorston Signed-off-by: Avi Halachmi Signed-off-by: Denys Vlasenko

ash: more Unix-style path fixes

2023-04-16T09:03:09+00:00

Commit 950b318a2 (ash: Unix-style paths, shell builtins and applets) broke running of Unix-style absolute paths from the shell by PATH search. The copy of the program name on the stack should only be used in the first call to tryexec() otherwise it interferes with the use of the stack by padvance(). Also, bring the code to handle Unix-style paths in find_command() into line with the revised code in shellexec().

ash: remove ASH_IGNORE_CR config option

2023-04-09T09:48:58+00:00

No further problems with CRLF handling have been reported. Remove the configuration option that allowed some recent changes to be turned off. Also, prevent some WIN32 code from being included in the POSIX build. The faulty code is from commit 64c8f5f3d (ash: add support for INT trap). These changes don't alter the default WIN32 build.

ash: special treatment for read builtin

2023-04-05T08:31:50+00:00

When INT is being trapped the read builtin gets special treatment in bash. In a top-level interactive shell interrupting the read with Ctrl-C clears the input and allows the user to enter a new string. In a subshell Ctrl-C really does interrupt the read and the trap isn't executed. zsh works similarly, except that in the latter case the trap is executed. dash interrupts the read and executes the trap in both cases. ksh also interrupts the read in both cases but only executes the trap in the first. Implement the bash behaviour. (GitHub issue #303)

ash: reinstate fix for ctrl-c issue

2023-04-05T08:31:14+00:00

Reinstate the change introduced in commit 96c104a61c (ash: try harder to avoid ctrl-c issue). It was removed during recent work on traps.
