| * libbb.h: fix logic selecting incorrect BB_STRTOOFF for !LFS configsDenys Vlasenko2021-10-081-3/+7
| | | | | | | | | | | | BB_STRTOOFF() was equal to bb_strtou(). On x86_64, it's incorrect. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | | | | | | | range_start was staying -1, and comparison meant to detect "is it the first sendfile that failed, or not the first?" was making incorrect decision.

| * find: Unify time comparisonsIsmael Luceno2021-10-071-16/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split the common part into a function, to be reused. The tail call is optimized, meaning now mmin/mtime just prepare arguments and jump into the common code, thus near zero overhead. This reduces code size slightly, e.g. on x86_64: text data bss dec hex filename 4806 0 0 4806 12c6 findutils/find.o.orig 4782 0 0 4782 12ae findutils/find.o Of course, the savings are even greater when implementing atime/ctime variants.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Finding the last component of a path didn't properly handle a mixture of slashes and backslashes, paths relative to another drive or bare UNC paths. The following were incorrect: $ basename /dir\\file dir\file $ basename c:file c:file $ basename //HOST/share share With this patch the results are now: $ basename /dir\\file file $ basename c:file file $ basename //HOST/share //HOST/share
* | win32: fix creation of relative symlinksRon Yorston2021-10-121-2/+5
| | | | | | | | | | | | | | | | Symlinks containing '.' or '..' (such as '../target', './target' or 'dir/./target') were successfully created but couldn't be accessed. It turns out Windows requires paths of that form to use backslashes rather than forward slashes.

* | win32: use is_dir_sep() everywhereRon Yorston2021-10-122-14/+12
| | | | | | | | | | The is_dir_sep() macro, which has been around since the start of busybox-w32, can be used instead of is_path_sep().
* | ash: prevent exit if background jobs are presentRon Yorston2021-09-261-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | 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 jobsRon Yorston2021-09-261-14/+16
| | | | | | | | | | | | | | | | | | 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 jobsRon Yorston2021-09-263-11/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 %<background job number>. 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 issueRon Yorston2021-09-221-0/+5
| | | | | | | | | | | | | | | | | | 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); }
