2019-02-27win32: make more use of common lazy loading codeRon Yorston2-27/+10
2019-02-25win32: fake permissions/ownership for inaccessible filesRon Yorston1-0/+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.
2019-02-22dpkg: enable in the default configurationRon Yorston3-2/+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
2019-02-21uname: drop support for ia64Ron Yorston1-4/+3
2019-02-21win32: use manifest provided by MinGW-w64Ron Yorston7-44/+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.
2019-02-20win32: remove unused include filesRon Yorston2-0/+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.
2019-02-19win32: stat(2) succeeds if fetching extra metadata failsRon Yorston5-17/+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.
2019-02-18win32: tidy up stat(2) implementationRon Yorston1-21/+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.
2019-02-18win32: avoid use of uninitialised metadata in stat(2)Ron Yorston1-2/+8
When additional metadata was being fetched the code for non-disk files used uninitialised data from the BY_HANDLE_FILE_INFORMATION structure.
2019-02-17win32: fix POSIX buildRon Yorston4-5/+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.
2019-02-17ash: updated support for hiding consoleRon Yorston4-10/+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.
2019-02-17ash: tidy up handling of -X optionRon Yorston1-8/+7
2019-02-16win32: make stat(2) fetch additional metadataRon Yorston12-16/+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.

2019-02-11vi: further fixes to undo after autoindentRon Yorston1-13/+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>

2019-02-06ash: make spawn_forkshell more like forkshellRon Yorston1-8/+12
These are cosmetic changes only. Make the arguments to spawn_forkshell more like those of forkshell. Since job control isn't currently supported in busybox-w32 the node argument isn't actually used. The node passed in the forkshell structure is used in the child code. It may be different from the node passed as an argument to spawn_forkshell which, in the upstream code, is forwarded to forkparent and forkchild.

fdisk, hexedit and ed calls read_line_edit in libbb/lineedit.c with NULL as first argument. On line 2373 of lineedit.c of busybox version 1.29.3, state->hist_file is referenced without checking the state->flag. This causes segmentation fault on fdisk, hexedit and ed on ARM Cortex-A9.

2019-02-02win32: add support for the euro currency symbolRon Yorston6-2/+103
The euro currency symbol was added to some OEM code pages. See: https://www.aivosto.com/articles/charsets-codepages-dos.html Add a configuration option (enabled by default) to support this. When enabled: - The read_key() function requests wide character key events. This allows the euro symbol to be entered regardless of the console OEM code page, though it needs to be available in the ANSI code page. - Conversions between OEM and ANSI code pages in winansi.c are modified to work around a bug in the Microsoft routines. - If the OEM code page is 850 when BusyBox starts it's changed to 858. This is the only currently supported OEM code page. Also, the shell read builtin is modified to use read_key() whenever input is being taken from the console.

This patch fixes the issue by making sure that the variable 'found' never makes a transition from 1 to 0, as this would mean that grep previously found a match on this input line.

2019-01-26ash: remove carriage returns from strings to be evaluatedRon Yorston1-0/+12
The shell could fail to evaluate strings containing carriage returns. For example: awk 'BEGIN { "set -ex\r\npwd\r\n" | getline }' </dev/null The string is passed as an argument to "sh -c". The "set" built-in fails because it attempts to treat the carriage return as an option. Although this is correct behaviour on Unix it may be unhelpful on Microsoft Windows. See GitHub issue #138.
2019-01-26win32: allow characters to be entered as ALTNNNRon Yorston1-3/+34
It wasn't possible to enter characters using Alt and the decimal character code. This was because the character is generated when the Alt key is released but the WIN32 implementation of read_key() ignored all key up events. Modify read_key() to ignore numbers entered on the numeric keypad with Alt pressed and to detect when Alt is released. Fixes GitHub issue #136.
2019-01-26vi: display pasted textRon Yorston1-1/+14
vi tries to avoid updating the display if more input is available. This didn't work when text was pasted in because a key release event was left in the event queue. When mysleep() is called to test for this condition allow up to one event to be present in the queue before reporting that input is available.
