* | win32: return reparse tag in struct statRon Yorston2022-05-191-0/+1
| | | | | | | | | | | | | | | | If a file is a junction or symlink return its tag in the st_tag member of struct stat. get_symlink_data() and is_symlink() also return the tag or zero, as appropriate.
* | jn: new appletRon Yorston2022-05-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Add a Windows-specific applet to create a directory junction. Usage: jn DIR JUNC where DIR must be an existing directory on a local drive and JUNC must not currently exist. There isn't a simple WIN32 API to create directory junctions. The implementation of mklink in ReactOS provided useful inspiration.
* | win32: make default PATH more likely to workRon Yorston2022-05-101-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | The default PATH defined as BB_PATH_ROOT_PATH is used: - to set PATH in the shell if the environment variable doesn't exist; - as the default in 'which' if there's no PATH env var; - when the option 'command -p' is given. Replace the Unix-centric default with something more likely to work on Microsoft Windows. No guarantees, though. (GitHub issue #253)
* | ash: export certain variables to the environment immediatelyRon Yorston2022-05-081-1/+5
| | | | | | | | | | | | | | | | | | | | | | 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 Yorston2022-05-061-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | which,ash: changes to which/command/typeRon Yorston2022-05-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change how 'which' detects if it was run from a standalone shell: the shell passes the undocumented '-s' option. This is stricter and more reliable than the previous method of checking the name of the binary. Add a function to determine the binary associated with a given applet name. This makes it possible for 'which' and 'command -v' to list the correct binary even for applets other than 'busybox'. For example, when the binary is called 'sh.exe' 'which sh' will report its path. In standalone shell mode 'command -V' and 'type' now report "xxx is a builtin applet" rather than "xxx is xxx", which is true but not very illuminating. (GitHub issue #248)
* | date: enable FEATURE_DATE_NANORon Yorston2022-04-221-0/+1
| | | | | | | | | | | | | | | | | | Provide a WIN32 implementation of clock_gettime(2), though only with support for CLOCK_REALTIME. This makes it possible to enable FEATURE_DATE_NANO which adds support for the %N date format. MinGW-w64 has clock_gettime(2) but it's in the winpthreads library and we don't want to bother with that.

* | win32: better handling of nested symlinksRon Yorston2021-08-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Our realpath(3) implementation uses xmalloc_follow_symlinks() to expand symlinks. This detects when symlinks are too deeply nested but didn't set errno, so anything calling realpath(3) was unable to say what had gone wrong. (For example, 'ls -L' or 'stat -L'.) Set errno to ELOOP. This then leads to the problem that Windows doesn't know about ELOOP so reports 'Unknown error'. Add a replacement for strerror(3) which returns a sensible message. Costs 96 bytes.
