ash: detect console state on shell start up

2023-08-20T12:35:20+00:00

Set 'noconsole' to match the actual state of the console (normal/ iconified) when the shell is started. Thus ShowWindow() will only be called if the actual state differs from the default or user defined state. Costs 20-24 bytes. (GitHub issue #325)

ash: detect native Windows environment on Wine

2023-08-17T14:09:14+00:00

The shell detected a native Windows environment by checking for a mixed-case 'Path' environment variable. This has always worked on Windows but recent versions of Wine have a 'PATH' environment variable. Check also for 'ComSpec'. Costs 24-48 bytes.

ash: improved support for trap built-in

2023-08-15T07:42:28+00:00

Make it possible to use the 'trap' built-in with command substitution, process substitution and in pipelines. Costs 200-256 bytes.

ash: code shrink

2023-08-15T07:38:21+00:00

Move the code to handle the case nprocs == 1 from jobtab_size() to procstat_size(). Saves 16 bytes.

ash: improved support for jobs built-in

2023-08-08T08:51:03+00:00

Pass job data to child shells. This makes it possible to use the 'jobs' built-in with command substitution, process substitution and in pipelines. Costs 576-672 bytes (GitHub issue #350)

ash: fix 'read' shell built-in (1)

2023-07-12T10:52:06+00:00

Consider this test case: { echo -n te; sleep 3; echo st; } | (read -t 1 x; echo "$x") - bash echoes "te" after 1 second. - Upstream BusyBox echoes an empty "$x" after 1 second. - busybox-w32 echoes an empty "$x" after 3 seconds. The delayed echo in busybox-w32 arises because the 'read' shell built-in omits the code to poll for input. Rearrange the code so that polling takes place. This doesn't address the difference between BusyBox and bash. Costs 48-64 bytes.

ash: properly echo console input to 'read' built-in

2023-07-12T10:52:06+00:00

The 'read' shell built-in echoed console input to stdout. Echo directly to the console instead. Costs 124-136 bytes.
