ash: prevent exit if background jobs are present

2021-09-26T07:59:03+00:00

If the user exits from an interactive shell while background jobs are running the console window won't terminate because the background jobs are still connected to it. Warn the user when this happens. They can either shut down the background jobs themselves or close the console window. This is implemented by repurposing the stoppedjobs() function which is otherwise unused in the WIN32 port.

ash: associate command names with jobs

2021-09-26T07:50:00+00:00

Reporting of background jobs is more useful if the commands associated with the jobs are displayed. Also, allow the kill builtin to kill jobs by matching their command names. This was previously disabled by commit f67224cb2 (ash: restrict valid job ids).

ash: additional support for background jobs

2021-09-26T07:33:36+00:00

The rationale for the jobs builtin in POSIX notes: The jobs utility is not dependent on the job control option, as are the seemingly related bg and fg utilities because jobs is useful for examining background jobs, regardless of the condition of job control. When the user has invoked a set +m command and job control has been turned off, jobs can still be used to examine the background jobs associated with that current session. Similarly, kill can then be used to kill background jobs with kill %. Although ash in busybox-w32 doesn't support job control it can handle background jobs. Allow the ASH_JOB_CONTROL setting to enable certain features: - the jobs builtin; - killing of jobs by job id in the kill builtin; - monitoring of changes to jobs. Since process groups aren't supported it's necessary to kill the processes constituting a background job individually. When doing this we ask kill(2) to kill all children too.

ash: fix FUNCNAME issue

2021-09-22T09:18:42+00:00

Commit c13f77823 (ash: adjust reinitvar() to allow for FUNCNAME) was incomplete. It didn't correctly pass the funcname variable during forkshell. This resulted in horrible failure when running a function like: f() { (echo $FUNCNAME); }

ash: improve signal handling

2021-09-21T12:24:00+00:00

Allow waitpid() to detect SIGTERM/SIGKILL by checking the (Windows) status returned by GetExitCodeProcess() and updating the Unix status to suit. This allows ash to detect when a process has been 'signalled'. Provide our own implementation of strsignal(3) which returns expanded text for SIGTERM/SIGKILL. Costs 192 bytes.

ash: avoid problems with non-zero DEBUG

2021-09-17T17:05:16+00:00

When DEBUG had a non-zero value the preprocessor complained that 'close' was being redefined. In a WIN32 build it's set to 'mingw_close'. Since this isn't necessary in ash it can be undefined without ill effects. DEBUG can be set to 1 or 2. In a WIN32 build this value was being used to calculate indices for optlist[], giving incorrect results. Using (DEBUG != 0) instead fixes this.

ash: adjust reinitvar() to allow for FUNCNAME

2021-09-17T11:54:21+00:00

The new FUNCNAME variable, like LINENO, needs special treatment during forkshell.

Merge branch 'busybox' into merge

Disable FEATURE_TIMEZONE for now.

ash: let ignoreeof only affect interactive shells

2021-09-14T06:25:58+00:00

Commit fb7d6c89 from Harald van Dijk's gwsh variant of ash (https://github.com/hvdijk/gwsh): ignoreeof is documented as only having an effect for interactive shells, but is implemented as having mostly the same effect for interactive shells as for non-interactive shells. Change the implementation to match the documentation.
