* libbb: fix detection of relative paths in xreadlink.csymlinkRon Yorston2021-03-011-0/+4
| | | | | | In xmalloc_follow_symlinks() the code to detect relative paths needs to be altered for WIN32. We don't want C:/path to be treated as a relative path.
* Fix `xmalloc_readlink()` againRon Yorston2021-03-011-1/+1
| | | | | | | | | | | | | | | | | | In e86a3ddd8 (win32: make readlink(2) implementation unconditional, 2021-02-12), we removed the special casing of `errno == ENOSYS` when trying to follow symlinks. However, that handling really was necessary: - When we followed a symlink, and found a non-symlink, and then called `readlink()` with that non-symlink, we got `errno == ENOSYS` on Windows (translated from `ERROR_NOT_A_REPARSE_POINT`), and we did want to stop the loop and return the current path in that case. (Noted by Johannes Schindelin.) - When readlink() called DeviceIoControl() for files on certain filesystems (e.g. FAT or a CDROM) it returned `errno == ENOSYS` (translated from ERROR_INVALID_FUNCTION). Revert the part of the patch which handled `ENOSYS` on Windows.
* win32: make readlink(2) implementation unconditionalRon Yorston2021-02-121-1/+1
| | | | | | | There doesn't seem to be much advantage in having readlink(2) as a configuration option. Making it unconditional reduces divergence from upstream and allows the removal of a check for ENOSYS that's been in busybox-w32 since the start.
