* | ash: export certain variables to the environment immediatelyRon Yorston2022-05-082-2/+12
| | | | | | | | | | | | | | | | | | | | | | The environment variables BB_OVERRIDE_APPLETS, BB_SKIP_ANSI_EMULATION and BB_SYSTEMROOT affect of the behaviour of the shell itself. Setting them as shell variables is insufficient for them to affect the current shell. When these three variables are exported from the shell they are now placed in the environment immediately. Conversely, when they're unset or unexported they're removed from the environment.
* | win32: allow preference for applets to be disabled at runtimeRon Yorston2022-05-062-1/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default busybox-w32 configuration enables the PREFER_APPLETS and SH_STANDALONE features. Sometimes it may be desirable to override the default preference for applets, for example, if an applet needs to be replaced by an external program with additional features. Add support for the environment variable BB_OVERRIDE_APPLETS. Its value may be: - a single dash ('-'): all applets are overridden; - a space-separated list of names: only the specified applets are overridden.
* | win32: minor adjustments to file permissionsRon Yorston2022-04-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Mask the file permission bits in mingw_umask(), not when it's called from run_applet_no_and_exit(). Rather than hardcode write permissions for group and other in file_attr_to_st_mode() and mingw_fstat() make them respect the current umask setting. In mingw_fstat() there's no need to check the mode using S_ISDIR(): the hardcoded mode doesn't set S_IFDIR. The compiler had already figured this out so there's no reduction in bloat.
