* Fix the flags for stat (again) (#601)mbartlett212026-06-221-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Revert "find: reset stat(2) flags before terminating" This reverts commit 228ee18fbe8cf408440e7bbe91db4ef201312983. * test: fix flags for stat with NOFORK test is a NOFORK applet, so the flags under mingw_stat may not have been reset before calling it. We have it so it also restores the flags after, since it could be called in the middle of another applet. This also needed a way to retrieve the flags, so they are just done through the return value. * Add comments about not having to restore flags Just for future reference * lineedit: use new flag restoring * win32: simplify mingw_access calling Since we now have a way to get the previous flags, mingw_access can be changed to ignore any stat flags * stat: comments from PR Adds 32 bytes.
* win32: Unix-like support for volume mountsRon Yorston2026-06-151-17/+31
| | | | | | | | | | | | | | | | | | Add code to distinguish between volume mount points and junctions. Volume mount points are to be treated like directries while junctions are like symlinks. Update the 'mntent' functions to scan drive letters first, then volume names and their associated mount points. By default the filesystem is returned as a drive letter, if possible, though the volume name is also returned. The function 'find_mount_point()' has been updated to use the new 'mntent' routines. Adds 772-803 bytes. Signed-off-by: Ron Yorston <rmy@pobox.com>
* win32: update current directory to target of symlinkRon Yorston2026-06-061-0/+4
| | | | | | | | | | | | | | | | If busybox.exe was started from a Windows command line in a directory which was the target of a symlink (or equivalent) 'ls' and 'stat' were unable to report the correct details of the current directory. Call 'chdir()' from the BusyBox main program to update our notion of our current directory. Adds 16 bytes. (GitHub issue #597) Signed-off-by: Ron Yorston <rmy@pobox.com>

* libbb: reverse performance regression in bb_copyfd_*Ron Yorston2026-05-101-1/+4
| | | | | | | | | | | | | Commit c4f24ec9d (libbb: try to mitigate 'cat /dev/urandom') resulted in a 'cat' to the terminal taking ~25% longer than before. Raising the isatty() call out of the loop reduces the penalty to ~1%. Adds 16 bytes in the 32-bit build. (GitHub issue #585)
* libbb: try to mitigate 'cat /dev/urandom'Ron Yorston2026-05-081-0/+11
| | | | | | | | | | | | | | | | | | | | | | | Now that '/dev/urandom' can be used directly, people with a sense of curiosity and adventure have tried running 'cat /dev/urandom' or 'cat </dev/urandom'. The 'cat' applet in BusyBox is so efficient and ANSI escape handling is so inefficient that this overwhelms the capabilities of the Windows console or terminal to the extent that it's unable to process Ctrl-C requests in a timely manner. To give it a chance to catch up, force 'cat' to take a short nap from time to time (very short, zero length) but only when it's writing to a tty. The call to Sleep() is in a separate function to avoid unnecessary bloat in 32-bit builds, where its presence upsets the stack and requires much larger code for stack access. Adds 48 bytes.

* crond: build tweaksRon Yorston2026-05-031-5/+5
| | | | | | | | | | | | | | | Using 'depends on FEATURE_SYSLOG' is unreliable because FEATURE_SYSLOG can't be set directly. A POSIX build with all applets that need syslog disabled *except* crond may fail. Revert to using 'select FEATURE_SYSLOG' in crond and exclude the unused syslog code on Windows. If crond is unable to run sendmail report this in the error message. Update all default Windows configurations. (GitHub PR #561)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LOOP_CONFIGURE ioctl is supported in 5.8 kernels and up. To have backwards compatibility there is a config option CONFIG_TRY_LOOP_CONFIGURE that will check if the ioctl exists and if not fall back to old way of configuring loop devices. Normally errno will be set to EINVAL when this ioctl does not exist. However, when kernel config CONFIG_COMPAT is enabled, then compat_ioctl is called. In that case -ENOIOCTLCMD is returned by loop device driver and generic ioctl wrapper will set errno to ENOTTY. Because busybox does not expect this it will fail to mount loop devices in this case. This patch fixes the check for the existence of the ioctl LOOP_CONFIGURE by checking if errno is one of both: EINVAL or ENOTTY. function old new delta set_loop 809 821 +12 Signed-off-by: Wouter Franken <wouter.franken_ext@softathome.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* | libbb: fix regression where 'which' output duplicate slashesRon Yorston2026-02-011-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an element of $PATH had a trailing slash 'which' displayed two slashes when an executable was found in that directory. This is a regression caused by upstream commit 49d9e06fb (libbb: modify find_executable() to not temporarily write to PATH). Prior to this commit find_executable() used concat_path_file() to build the path of the executable. This avoids including duplicate slashes in its output. The new code didn't. Add a test in find_executable() to detect the problem. It still fails if there are multiple trailing slashes. Don't do that. Adds 48 bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, scripts/mkwcwidth generated a wcwidth implementation based on input from the python wcwidth: https://github.com/jquast/wcwidth . However, that project is not updated frequently, and the less dependencies - the better. This new script instead prints an implementation based directly on the original Unicode files - which it can also download. It generates the same code as before (same data structures, etc). It was then used to re-generate libbb/wcwidth_alt.c, as follows: ./scripts/mkwcwidth DL=15.1.0 FAST_FUNC > libbb/wcwidth_alt.c This is the same Unicode version as the previous file, just to make the codepoint differences visible easily. These differences are very small, and the script itself explains where and why it differs from https://github.com/jquast/wcwidth . Next commits will update the tables to the latest unicode version.

However, there's at least one upstream unicode code path which was not touched until now - printable chars. This code is used by applets like "ls" to display "?" instead of non-printable chars, where upstream considers byte values above 127 as non-printable, but the busybox-w32 code should consider them printable when unicode is disabled (ANSI codepage). We already have code for that when unicode is disabled at build time (at printable_string2), but when unicode is enabled at build time then it enters a different code path (which still tests dynamically whether unicode is enabled - and correctly deduces that it isn't when unicode is disabled despite the utf8 manifest). Modify unicode_conv_to_printable2 similar to how printable_string2 is modified - but only when unicode is disabled due to the manifest not being in effect (unicode build on win XP/7/8). A unicode build on XP/7/8 _should_ now behave reasonably close to a non-unicode build on such systems. Known issues: There's one known issue, and that's tab completion doesn't case-fix the completion. E.g. ~/desk<tab> completes to ~/desktop/ instead of to ~/Desktop/ (capital D). This issue exists in unicode builds also on win10+, and is caused by the fact that when unicode is enabled at build-time, line-editing uses (32bit) wchar_t, and of the mingw changes in line-edit, only the backslash-to-slash was ported also to the wchar_t editing, while case-fix was not (see FIXME at libbb/lineedit.c in commit 0efc7474). status: This combination of unicode-enabled build running on XP/7/8 was NOT tested extensively, so some issues might remain, but other than the case-fix with tab-completion, there are no known issues. Main area where more testing is needed is editing (probably mainly interactive shell command prompt and vi). Testing: To test how a unicode-enabled build behaves when unicode is disabled in runtime, other than actually running it on win XP/7/8, one way would be to find a combination of build-config values to enable all the unicode features but not the manifest itself, but that's tricky. Instead, one could simply delete the manifest from a pre-compiled binary (mingw{64u,32w}_defconfig), so that it would run in ANSI mode even on win10+, with the build-time unicode code paths still enabled at the binary. One tool to edit windows binaries is https://github.com/avih/perc . To delete the manifest, use "perc -D -t MANIFEST busybox.exe" .
* | win32: add a config for 32-bit build with UnicodeRon Yorston2025-12-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that a binary with a UTF-8 manifest can run on Windows XP it's possible to configure a build which supports Unicode on Windows 10+ but which still runs on legacy systems. - Add the config file mingw32w_defconfig. This is a 32-bit build with the UTF-8 manifest which also runs on legacy systems. - A new config option, FEATURE_FAIL_IF_UTF8_MANIFEST_UNSUPPORTED, allows the check for legacy systems to be skipped. - An incompatibility with Windows XP in writeCon_utf8() has been fixed.
