* | win32: make more use of common lazy loading codeRon Yorston2019-02-272-27/+10
| |
* | 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

* | 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.

| | | | | | | | | | | | | | Since symlinks aren't supported in busybox-w32 remove more of the code that handles them. Saves 64 bytes.

| * vi: further fixes to undo after autoindentRon Yorston2019-02-111-13/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit bb983f30e (vi: fix faulty undo after autoinsert) has a number of problems: - The commit message refers to 'autoinsert' when it really means 'autoindent'. - The indentation of undo_push_insert() was incorrect. - Most seriously the commit only fixed the problem for cases where the indentation was exactly one character. 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>
