| * vi: searches in colon commands should wrapRon Yorston2021-08-221-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The '/' and '?' search commands wrap to the other end of the buffer if the search target isn't found. When searches are used to specify addresses in colon commands they should do the same. (In traditional vi and vim this behaviour is controlled by the 'wrapscan' option. BusyBox vi doesn't have this option and always uses the default behaviour.) function old new delta colon 4033 4077 +44 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 44/0) Total: 44 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
| * rev: correct output for long input linesRon Yorston2021-08-222-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The input buffer is initialised to a reasonable size and extended if necessary. When this happened the offset into the buffer wasn't reset to zero so subsequent lines were appended to the long line. Fix this and add some tests. function old new delta rev_main 377 368 -9 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-9) Total: -9 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* | busybox: bring help handling into line with upstreamRon Yorston2021-08-161-5/+5
| | | | | | | | | | Upstream has fixed a problem with 'busybox --help' so it's possible to remove another gratuitous divergence.
* | win32: code shrink uname(2)Ron Yorston2021-08-161-8/+4
| | | | | | | | | | | | | | If GetVersionEx() fails just assume the OS version numbers remain set to zero and print them as-is. Saves 48 bytes.
* | printf: improved error handlingRon Yorston2021-08-151-19/+23
| | | | | | | | | | | | | | | | | | | | | | | | The printf applet is NOFORK and is used to implement the printf command in ash. It should therefore be careful about handling memory allocation failures. If vasprintf() or realloc() fail the applet now carries on as best it can. This may result in some lost output but at least the shell will survive. Saves 32 bytes.
* | win32: implement utimes(2) using utimensat(2)Ron Yorston2021-08-151-38/+18
| | | | | | | | Saves 176 bytes.
* | win32: tidy up fetching of system directoryRon Yorston2021-08-141-14/+17
| | | | | | | | | | | | | | | | | | | | | | | | Add a new function, getsysdir(), to fetch and cache the system directory. This avoids the non-intuitive use of getpwuid() in get_system_drive(). The call to GetSystemDirectory() in get_proc_addr() can't be replaced because getsysdir() calls realpath() which requires a call to get_proc_addr(). No change in the size of the binary.
* | win32: code shrinkRon Yorston2021-08-141-14/+14
| | | | | | | | | | | | | | | | | | There doesn't seem to be any need to call OpenThreadToken() in file_owner(): OpenProcessToken() should suffice. Also, tidy up gethomedir() without any change in functionality. Saves 56 bytes.
* | win32: treat devices as character special filesRon Yorston2021-08-131-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 15fcbd19c (win32: special case for devices files in stat(2)) added special treatment in stat(2) for device files. As a result of this change device files appeared to be regular files which broke the use of /dev/null with noclobber in the shell. Device files now appear as character special files (as they do on Unix). GitHub issue #225.
* | find_mount_point: code shrinkRon Yorston2021-08-121-8/+2
| | | | | | | | | | | | | | Use xrealloc_getcwd_or_warn() instead of a hand-rolled WIN32 equivalent. Saves 84 bytes.
* | win32: better handling of nested symlinksRon Yorston2021-08-123-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | nproc: code shrinkRon Yorston2021-08-101-24/+12

* | win32: code shrink character class detectionRon Yorston2021-08-095-18/+83
| | | | | | | | | | | | | | Add a routine to detect the names of character classes. Use it in fnmatch(3) and regcomp(3), replacing local code in the former. Saves 216 bytes.
* | win32: fix fnmatch(3) handling of xdigitRon Yorston2021-08-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The glob pattern '[[:xdigit::]]*' didn't return the matches expected. It turns out the implementation (from glibc) fails to detect 'xdigit' as a valid character class. Changing the definition of CHAR_CLASS_MAX_LENGTH to 7 fixes the problem. This was never an issue in glibc because it uses a different definition. More modern versions of fnmatch(3) in glibc and gnulib also make CHAR_CLASS_MAX_LENGTH long enough. The code for fnmatch(3) was taken from glibc at commit 7814856974388a856a575fa45f88d502c8a1ab29. This was the last version before the code was rearraged to better support multibyte characters.
* | win32: tidy up time conversionsRon Yorston2021-08-091-7/+3
| | | | | | | | | | | | | | Remove filetime_to_time_t(): it's no longer used. Align style of time{spec,val}_to_filetime() to make it easier to compare what they do.
* | win32: code shrinkRon Yorston2021-08-083-12/+11
| | | | | | | | | | | | | | | | | | Save a few bytes: - When collecting entropy prefer functions we call elsewhere. - In uname(2) set 32-bit processor type to i686 and tweak it for i386.
* | win32: improved keycode detectionRon Yorston2021-08-061-42/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In read_keys(): - Identify all keys on the numeric pad used to enter character codes. Otherwise Alt-Left/Alt-Right on the numeric pad are treated as word movements in command line editing, preventing the entry of character codes containing 4 or 6. - Add modifier flag bits to the virtual keycodes we care about. This means, for example, that only the unmodified Up/Down arrow keys move through shell history, not Up/Down plus arbitrary modifiers.
