* | realpath: improved support for Windows pathsRon Yorston2021-10-132-7/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upstream commit 94eb1c4dc (libbb: better coreutils compatibility for realpath) made some changes to xmalloc_realpath_coreutils(). This now needs to be updated to handle Windows paths. - Expose the macro is_unc_path() and part of the recent change to bb_get_last_path_component_nostrip() as a separate funtion, get_last_slash(); - Convert a couple of errors relating to network filesystems to ENOENT; - Adjust xmalloc_realpath_coreutils() to handle Windows directory separators, relative paths and UNC paths.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add some tests which coreutils realpath pass but BusyBox realpath fails (bar one). Adjust xmalloc_realpath_coreutils() so the tests pass: - Expand symbolic links before testing whether the last path component exists. - When the link target is a relative path canonicalize it by passing it through xmalloc_realpath_coreutils() as already happens for absolute paths. - Ignore trailing slashes when finding the last path component and correctly handle the case where the only slash is at the start of the path. This requires ignoring superfluous leading slashes. - Undo all changes to the path so error messages from the caller show the original filename. function old new delta xmalloc_realpath_coreutils 214 313 +99 Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Like the '@' format these dates aren't relative to the user's current timezone and shouldn't be subject to DST adjustment. - The implementation uses the strptime() '%z' format specifier. This an extension which may not be available so the use of timezones is a configuration option. - The 'touch' applet has been updated to respect whether DST adjustment is required, matching 'date'. function old new delta parse_datestr 624 730 +106 static.fmt_str 106 136 +30 touch_main 388 392 +4 date_main 818 819 +1 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 4/0 up/down: 141/0) Total: 141 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | Upstream has fixed a problem with 'busybox --help' so it's possible to remove another gratuitous divergence.
* | find_mount_point: code shrinkRon Yorston2021-08-121-8/+2

* | 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.
* | win32: more efficient tests for executablesRon Yorston2021-07-262-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | file_is_executable() calls access(2) and stat(2); in this case our WIN32 implementation also calls stat(2). Avoid this unnecessary duplication by copying the required test from the WIN32 access(2). In find_executable() it's possible to avoid calling file_is_executable() if add_win32_extension() returns TRUE as the latter will already have verified that the file is executable. Replace a call to file_is_executable() in the tab completion code with the equivalent tests, avoiding (up to) two calls to stat(2). These changes don't affect the size of the binary and should be faster.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the structure returned by getmntent(3) static so it persists after endmntent(3) closes the stream. No current caller in the WIN32 port needs this functionality but it's good to match the documented behaviour. Populate more fields of the mntent structure in find_mount_point(). This is required to support the df -t and -T flags recently added upstream. The static structures used here are allocated on demand. Separate static structures are used in each case because df iterates through mounts calling statfs(2) on each and the WIN32 implementation of statfs(2) calls find_mount_point().
