* | ash: add options to control globbing of hidden filesRon Yorston2023-09-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add shell options: - 'nohiddenglob' excludes files with the hidden attribute from globbing - 'nohidsysglob' excludes files with the hidden and system attributes from globbing If both options are enabled 'nohiddenglob' takes precedence. These options also affect tab completion. Files that are hidden because they start with a period aren't affected (unless they also have the hidden attribute). Costs 160-208 bytes. (GitHub issue #367)
* | win32: convert exit codesRon Yorston2023-09-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add two utility functions to convert Windows process exit codes. - exit_code_to_wait_status() converts to a POSIX wait status. This is used in ash and the implementations of system(3) and mingw_wait3(). - exit_code_to_posix() converts to a POSIX exit code. (Not that POSIX has much to say about them.) As a result it's possible for more applets to report when child processes are killed as if by a signal. 'time', 'drop' and 'su -W', for example. Adds 64-80 bytes.
* | ps: increase length of 'comm' fieldRon Yorston2023-08-291-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Linux the command name associated with a process (as can be obtained from '/proc/<PID>/comm') is truncated to 16 characters. Thus upstream BusyBox only allows 16 characters for the 'comm' field in 'ps'. There's no need for such a constraint in busybox-w32. Moreover, the command name is used for the full command line ('args' field) in most cases. This field is allowed to be rather long in 'ps' so it's not expected to be truncated. Still, to avoid diverging too much from upstream it's best to have some measure of truncation. Increase the allowed length of the command name to 32 characters. Adds 16 bytes. (GitHub issue #358)
* | win32: UCRT: avoid I64 printf format warningsAvi Halachmi (:avih)2023-08-281-2/+3
| | | | | | | | | | | | | | | | Builds without warnings on: mingw-msvcrt gcc 13.2 i686/x86-64 (w64devkit). mingw-ucrt gcc 13.1/13.2 i686/x86-64 (winlibs). Where previously both the ucrt builds warned about I64.
* | win32: replace readlink(2)Ron Yorston2023-08-211-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Windows implementation of readlink(2) has caused problems in the past. As, for example, with commit c29dc205d2 (win32: fix implementation of readlink(2)). Most uses of readlink(2) in BusyBox are actually calls to the (considerably more convenient) library function xmalloc_readlink(). Implement a Windows version of that and used it instead of readlink(2). This improves the handling of symbolic links (and similar reparse points) in CJK and UTF-8 code pages. Saves 48-80 bytes.
* | ash: detect console state on shell start upnoconsole2Ron Yorston2023-08-201-1/+0
| | | | | | | | | | | | | | | | | | | | | | Set 'noconsole' to match the actual state of the console (normal/ iconified) when the shell is started. Thus ShowWindow() will only be called if the actual state differs from the default or user defined state. Costs 20-24 bytes. (GitHub issue #325)

* | win32: support build with FEATURE_UNICODE_SUPPORTAvi Halachmi (:avih)2023-07-222-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FEATURE_UTF8_MANIFEST enables Unicode args and filenames on Win 10+. FEATURE_UTF8_INPUT allows the shell prompt to digest correctly Unicode strings (as UTF8) which are typed or pasted. This commit adds support for building with FEATURE_UNICODE_SUPPORT (mostly by supporting 32 bit wchar_t which busybox expects): - Unicode-aware line-edit - for the most part cursor movement/del being (UTF8) codepoint-aware rather than assuming that one-byte equals one-char-on-screen. - Codepoint-aware operations in some other utils, like rev or wc -c. - When UNICODE_COMBINING_WCHARS and UNICODE_WIDE_WCHARS are enabled, some screen-width-aware operations, like with fold, ls, expand, etc. The busybox Unicode support is incomplete, and even less so with the builtin libc replacement functions, like wcwidth, which are active when UNICODE_USING_LOCALE is unset (mingw lacks those functions). FEATURE_CHECK_UNICODE_IN_ENV should be set so that Unicode is not hardcoded but rather depends on the ANSI codepage and some env vars: LC_ALL=C disables Unicode support, else it's enabled if ACP is UTF8. There's at least one known issue where the tab-completion-prefix-case is not updated correctly, e.g. ~/desk<tab> completes to ~/desktop/ instead of ~/Desktop/, because the code which handles it exists only at the non-unicode code paths, but that's not very critical. That seems to be the only case where mingw-specific code is disabled when Unicode is enabled, but there could be other unknown issues. None of the Unicode options is enabled by default, and the next commit will make it easier to create a build which supports Unicode.

* | ash: properly echo console input to 'read' built-inRon Yorston2023-07-121-0/+1

* | win32: the great UTF8 ReadConsoleInput hackAvi Halachmi (:avih)2023-06-281-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 597d31ee (EURO_INPUT), ReadConsoleInputA is the default. The main problem with that is that if the console codepage is UTF8, e.g. after "chcp 65001", then typing or pasting can result in a crash of the console itself (the Windows Terminal or cmd.exe window closes). Additionally and regardless of this crash, ReadConsoleInputA is apparently buggy with UTF8 CP also otherwise. For instance, on Windows 7 only ASCII values work - others become '?'. Or sometimes in Windows 10 (cmd.exe console but not Windows terminal) only key-up events arrive for some non-ASCII codepoints (without a prior key-down), and more. So this commit implements readConsoleInput_utf8 which delivers UTF8 Regardless of CP, including of surrogate pairs, and works on win 7/10. Other than fixing the crash and working much better with UTF8 console CP, it also allows a build with the UTF8 manifest to capture correctly arbitrary unicode inputs which are typed or pasted into the console regardless of the console CP. However, it doesn't look OK unless the console CP is set to UTF8 (which we don't do automatically, but the user can chcp 65001), and editing is still lacking due to missing screen-length awareness. To reproduce the crash: start a new console window, 'chcp 65001', run this program (or busybox sh), and paste "ಀ" or "😀" (U+0C80, U+1F600) #include <windows.h> int main() { HANDLE h = GetStdHandle(STD_INPUT_HANDLE); INPUT_RECORD r; DWORD n; while (ReadConsoleInputA(h, &r, 1, &n)) /* NOP */; return 0; }
* | win32: don't assume console CP equals OEM CPAvi Halachmi (:avih)2023-06-281-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, console input was converted to the ANSI codepage using OemToChar[Buff], and ANSI to console conversion used CharToOem[Buff]. However, while typically true by default, it's not guaranteed that the console CP is the same as the OEM CP. Now the code uses the console input/output CP as appropriate instead of the OEM CP. It uses full wide-char conversion code, which was previously limited to FEATURE_EURO, and now may be used also otherwise. While at it, the code now bypasses the conversion altogether if the src/dst CPs happen to be identical - which can definitely happen. Other than saving some CPU cycles, this also happens to fix an issue with the UTF8 manifest (in both input and output), because apparently the Oem/Char conversion APIs fail to convert one char at a time (which is not a complete UTF8 codepoint sequence) even if both the OEM and the ANSI CPs are UTF8 (as is the case when using UTF8 manifest). Conversion is also skipped: - if the converted output would be longer than the input; - if the input length is 1 and the input is multi-byte.

* | win32: another BB_OVERRIDE_APPLETS fixRon Yorston2023-06-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support for conditionally replacing applets with external commands requires the ability to check whether a given command name is present on PATH. This was being done using the PATH environment variable, which works in commands run by the shell but not in the shell itself. - The shell uses the *shell* variable PATH to look for executables. This may not be the same as the *environment* variable. - 'command -p' uses an entirely different PATH. Applet look-up in the shell is now treated as a special case, with the actual PATH being used passed to the look-up code in a global variable. This doesn't affect tab completion in the shell: whether a completion is an applet or an external command is irrelevant. Costs 152-288 bytes. (GitHub issue #329)
* | win32: fix euro symbol handlingRon Yorston2023-06-021-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | Commit 2b4dbe5fa (libbb: speed up bb_get_chunk_from_file()) speeded up grep by a factor of two. However, it introduced a call to OemToCharBuff() in bb_get_chunk_from_file() which didn't have the fix for the euro symbol from commit 93a63809f9 (win32: add support for the euro currency symbol). Export the fixed version of OemToCharBuff() and use it. Saves 8 bytes (64-bit), adds 28 bytes (32-bit)
* | ash: enable 'set -/+o noconsole'Ron Yorston2023-06-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the 'noconsole' shell option could only be set as a shell command line option. Allow it to be changed from within the shell by 'set -o noconsole' or 'set +o noconsole'. The console window is now minimised rather than hidden. This makes it easier for the user to access the console when 'noconsole' is in effect. Adds 8-32 bytes. (GitHub issue #325)
* | win32: crtl-c interrupts non-console applicationsRon Yorston2023-05-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 9db9b34ad (win32: ignore ctrl-c in parent of execve(2)) prevented a parent process from reacting to Ctrl-C while it was waiting for its child to complete. This avoids the problem where a shell and an interactive child end up competing for input after a Ctrl-C. However, a child process which isn't attached to the console (a GUI application, for example) can't then be killed by Ctrl-C. Instead of completely ignoring Ctrl-C give the parent a handler which detects if its child is attached to the console. If so it's left to handle Ctrl-C itself and the parent ignores the interrupt. If not the parent terminates the child and all its children as if by SIGINT. Costs 200 bytes.
* | win32: changes to signal handlingRon Yorston2023-05-231-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use an exit code of the form (signal << 24) when a process exits due to a signal. This replaces the previous use of (signal + 128). This makes it easier to distinguish exit codes from signals. Allow kill(2) to handle all defined signals, not just EXIT, TERM and KILL. The kill and timeout applets now accept any defined signals. Convert certain Windows status codes Unix-style signal codes. In ash: - Exit as if with SIGINT in raise_interrupt() rather than call raise(SIGINT). The latter returns an exit code of 3. - Detect if a child process exits as if with SIGINT. If not and if the parent is an interactive top-level shell, reset pending_int. This prevents the parent from seeing an INT if the child hasn't reported it exited due to INT. (Probably due to it being an interactive shell.) Costs 132-136 bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tab-completion code treated all matches as case-insensitive because that's how Microsoft Windows handles filenames. This is now inadequate, as shell builtins, functions and aliases are case sensitive. Modify the treatment of case-sensitivity in tab completion: - Track whether each potential match is case-insensitive (filename) or case-sensitive (shell builtin, function or alias). - When comparing matches use a case-insensitive comparison if either value is a filename. Otherwise use a case-sensitive comparison. Adds 64 bytes.

As before, other signals (from a limited list) are accepted but their traps don't have any effect. There's some variability in how shells handle traps. This patch upholds that proud tradition. Various changes are needed to make this work: - Line editing has a new flag to ignore Ctrl-C. - If INT is being trapped or ignored don't call raise_interrupt(). - A minimal implementation of dotrap() is provided. - Call dotrap() when the read builtin or line input detect Ctrl-C. - Adjust Ctrl-C detection when the INT trap is changed. - Set may_have_traps when an INT trap is set.

| | | | | | | | | | | | | | | | | | | | | | Commit 93a63809f9 (win32: add support for the euro currency symbol) caused all invocations of busybox-w32 to change code page 850 to 858.

Instances of PowerShell started by the `drop` applet during ssh login thus no longer have their code page adjusted.
* | runuser: add 'drop' as an alias for runuserRon Yorston2023-03-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'drop' alias for 'runuser' relaxes a number of constraints that were introduced for compatibility: - It works even if the current process doesn't have elevated privileges. - It isn't necessary to specify the name of the user. - Any command can be invoked, not just the BusyBox shell. - If the command doesn't specify a path 'drop' will first look for a BusyBox applet then search PATH. Adds 320-336 when built along with runuser. (GitHub issue #240)
* | win32: code shrink detection of executablesRon Yorston2023-03-161-1/+2

* | runuser: new appletRon Yorston2023-03-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a cut down, Windows-specific implementation of `runuser` from util-linux. This allows elevated privileges to be dropped when running in an SSH session. It also works when using `su` or starting busybox-w32 'as administrator'. There are complications: - The method used to drop privileges leaves the access token in the TokenIsElevated state. Detecting this is likely to be fragile. - The unprivileged shell is started by CreateProcessAsUserA(). In older versions of Windows this has to be loaded dynamically. Adds about 900 bytes. (GitHub issue #240)
* | win32: virtual terminal input fixesRon Yorston2023-03-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | - Disable ENABLE_PROCESSED_INPUT in raw mode. Otherwise ^C isn't immediately detected during shell command line editing with virtual terminal input enabled. - Switch read_key()/unix_readkey() to windows_read_key()/read_key(). This allows the shell `read` builtin to use windows_read_key(). Without this change `read` fails when virtual terminal input is enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the environment variable BB_TERMINAL_MODE as a more general way of controlling console/terminal mode setting. The default remains unchanged: use virtual terminal mode for output if possible but fall back to the console API with emulated ANSI escape sequences. Currently valid settings are: 0 Force use of console mode 1 Force use of virtual terminal mode for output 5 Prefer virtual terminal mode for output, fall back to console Other values won't do anything useful until code elsewhere has been updated. BB_SKIP_ANSI_EMULATION remains available for backwards compatibility. If both variables are set BB_TERMINAL_MODE takes precedence.
* | win32: only count subdirectories if necessaryRon Yorston2023-01-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 7fb95a2a5 (win32: try to get link count for directories) allowed stat(2) to report accurate values of st_nlink for directories. There are only a couple of places in busybox-w32 where these values are required. Disable counting of subdirectories by default and only enable it when necessary. Microsoft kindly provide directories to test edge cases like this: C:/Windows/WinSxS (contains many subdirectories) C:/Windows/WinSxS/Manifests (contains many files) Adds 84-112 bytes.

* | win32: revised implementation of setlinebuf(3)Ron Yorston2022-12-311-1/+1
| | | | | | | | | | | | | | | | | | Microsoft Windows' setvbuf() doesn't support line buffering and doesn't accept 0 as a valid value for the buffer size argument. Replace the old macro definition with an implementation that doesn't do anything. It's only used if debug is enabled in ash so there's no effect on the default build.
* | win32: remove declaration of vfork(2)Ron Yorston2022-10-311-1/+0
| | | | | | | | | | | | | | Since vfork(2) is never used in busybox-w32 there's no need to declare it. Doing so provokes clang to issue a warning. (GitHub issue #239)
