* | su, wget: use magic '--busybox' flagRon Yorston2019-03-082-6/+4
| | | | | | | | | | | | I've been a bit lax about ensuring the --busybox flag is passed in command lines. It's needed to avoid problems if the binary is called something like sh.exe.
* | ash, su: add -d flag to set directory in ash, use it in suRon Yorston2019-03-082-5/+35
| | | | | | | | | | | | | | | | When busybox-w32 is installed in C:/Windows/System32 su doesn't run in the same directory as its parent as intended. Work around this by adding a flag to the shell to set the working directory.
* | su: add a basic implementation for WIN32Ron Yorston2019-03-074-2/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the undocumented 'runas' verb in a call to ShellExecuteEx() to run a shell with elevated privileges. Because of the way ShellExecuteEx() works this: - requires that you acknowledge a User Account Control prompt (if you're an Administrator); - requires that you enter an Administrator's password (if you aren't an Administrator); - creates a separate console window for the privileged shell. Variables from the parent shell aren't passed to its privileged child, only variables from the environment. It's possible to specify a command to run when the shell starts. This can be used to pass shell variables: su -c "HELLO='hello world'; GOODBYE=$GOODBYE" Or do fancy things like: su -c "ls -l; read -p 'Hit return to exit: '; exit" It's probably best to put double quotes around the command and use single quotes inside it. Apparently ShellExecuteEx() requires double quotes to be entered in triplicate: su -c 'HELLO="""hello world"""'
* | win32: canonicalize path in chdir(2)Ron Yorston2019-03-062-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | Provide an implementation of chdir(2) which canonicalizes the path to resolve symlinks. Otherwise changing to a symlinked directory confuses 'ls -l' because it thinks '.' is a link rather than a directory. OTOH, using 'cd' in the shell to change to a symlinked directory now results in a mismatch between the shell's idea of where we are and what's displayed in the prompt. But upstream BusyBox does that too so it must be OK.
* | win32: implement readlink(2)Ron Yorston2019-03-067-9/+92
| | | | | | | | | | | | | | | | | | | | Provide an implementation of readlink(2) based on code from Git for Windows. This version only supports symbolic links, not mount points, as the latter seem to work well enough as-is. With this change the ls and stat applets can display the targets of symbolic links. The readlink applet has been enabled in the default configuration.
* | win32: let realpath(3) succeed on WinXP/ReactOSRon Yorston2019-03-061-8/+14
| | | | | | | | | | | | Allow realpath(3) to return successfully on platforms that don't support GetFinalPathNameByHandleA(). It may still have done some useful work.
* | win32: drop argument from err_win_to_posix()Ron Yorston2019-03-064-10/+10

* | win32: improved results for symlinks from stat(2)Ron Yorston2019-03-051-36/+56
| | | | | | | | | | | | | | | | The file size and times reported when Windows follows a symlink are incorrect. To get the correct values canonicalize the path and try again. Also fetch the correct device id and inode for symlinks.
* | win32: change handling of trailing slashes in stat(2)Ron Yorston2019-03-041-40/+11
| | | | | | | | | | | | | | | | | | | | The code to implement stat(2) works around the fact that getting the attributes of a file fails if its name ends with a path separator. Directory names with a trailing path separator work fine. Why bother with this workaround? Linux doesn't. Instead try to return a meaningful error code.
* | win32: simplify utimes(2) implementationRon Yorston2019-03-041-31/+6
| | | | | | | | | | | | | | | | | | | | | | SetFileTime only needs FILE_WRITE_ATTRIBUTES access, not full read/write access. Therefore it isn't necessary to change the permissions of read-only files. The flag FILE_FLAG_BACKUP_SEMANTICS is required to access directories but does no harm if used on a file. As a result there's no need to get file attributes.
* | ls: use correct column width for WIN32 inodesRon Yorston2019-03-041-0/+4
| |
* | win32: let stat(2) report numeric uids for local usersRon Yorston2019-03-022-10/+49
| | | | | | | | | | | | | | | | | | | | | | Further extend file identification so stat(2) returns the relative identifier as a numeric uid for files with owner SIDs that look like a local or domain user. See: https://blogs.technet.microsoft.com/markrussinovich/2009/11/03/the-machine-sid-duplication-myth-and-why-sysprep-matters/ https://cygwin.com/cygwin-ug-net/ntsec.html
* | ash: add an option to enable case-insensitive filename globbingRon Yorston2019-03-011-4/+26
| | | | | | | | | | The 'nocaseglob' shell option enables case-insensitive filename globbing. By default globbing is case-sensitive.
* | libbb: copy entire match during tab-completionRon Yorston2019-03-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | Because tab-completion is case-insensitive the matching text might differ from what the user typed. Insert the whole of the matching text, not just the tail. Thus: $ cd doc<TAB> now expands to: $ cd Documents/
* | win32: make stat(2) try to identify the owner of filesRon Yorston2019-03-014-9/+76
| | | | | | | | | | Extend stat(2) so it tries to determine whether a file belongs to the current user or not. If not it's said to belong to root.

* | win32: fake permissions/ownership for inaccessible filesRon Yorston2019-02-251-0/+5
| | | | | | | | | | If stat(2) knows a file exists but can't obtain additional metadata for it give it root ownership and no permissions for other.
* | dpkg: enable in the default configurationRon Yorston2019-02-223-2/+7
| | | | | | | | | | | | | | | | | | | | BusyBox's dpkg is marginally more useful than rpm because it maintains package status. Run the following commands to initialise the filesystem: mkdir -p /var/lib/dpkg/info touch /var/lib/dpkg/status
* | uname: drop support for ia64Ron Yorston2019-02-211-4/+3

* | win32: use manifest provided by MinGW-w64Ron Yorston2019-02-217-44/+1
| | | | | | | | | | | | | | | | | | The manifest included here wasn't effective in telling Windows about version compatibility. Use the default manifest provided by MinGW-w64 instead. On Fedora this requires installing the mingw32-windows-default-manifest and/or mingw64-windows-default-manifest packages.
* | win32: remove unused include filesRon Yorston2019-02-202-0/+0
| | | | | | | | | | | | Upstream commit d9aabfe578 (make busybox more portable) moved a couple of include files into platform-dependent code so we no longer need dummy versions.
* | win32: stat(2) succeeds if fetching extra metadata failsRon Yorston2019-02-195-17/+19
| | | | | | | | | | | | | | | | | | Some files can't be opened to fetch additional metadata. When that happens allow stat(2) to successfully return what data it has. In a few cases where the inode number is used to determine if files are identical ignore invalid inode numbers.
* | win32: tidy up stat(2) implementationRon Yorston2019-02-181-21/+22
| | | | | | | | | | | | | | Since st_nlink now depends on st_mode it should be set after st_mode is initialised. Rearrange the code to fetch extra metadata.
* | win32: avoid use of uninitialised metadata in stat(2)Ron Yorston2019-02-181-2/+8
| | | | | | | | | | | | When additional metadata was being fetched the code for non-disk files used uninitialised data from the BY_HANDLE_FILE_INFORMATION structure.
* | win32: fix POSIX buildRon Yorston2019-02-174-5/+28
| | | | | | | | | | | | There were a few places where changes intended for the WIN32 build also affected the POSIX build. Fix these so the result of 'make defconfig; make' for busybox-w32 is identical to upstream BusyBox.
* | ash: updated support for hiding consoleRon Yorston2019-02-174-10/+21
| | | | | | | | | | | | | | | | Move the code to hide the console to a separate function in win32/mingw.c. Use lazy loading to avoid problems on platforms where the require APIs aren't supported (PR #70). Enable console hiding in the default 64-bit configuration.
* | ash: tidy up handling of -X optionRon Yorston2019-02-171-8/+7
| |
* | win32: make stat(2) fetch additional metadataRon Yorston2019-02-1612-16/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the WIN32 implementation of stat(2) to fetch inode number, device id and number of hardlinks. This requires opening a handle to the target file so it will be slower. A number of features can be enabled or start to work: - tar can detect if an archive is being stored in itself; - find can support the -inum and -links options; - ls can display inode numbers; - diff can detect attempts to compare a file with itself; - du has better support for hardlinked files; - cp can detect attempts to copy a file over itself.

This is because undo_push() only allows single characters to be queued for UNDO_INS_QUEUED. Lifting this restriction allows the example given in the previous commit message (with a three character indent) to work. function old new delta undo_push 406 435 +29 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 29/0) Total: 29 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
