2015-07-26win32: remove setitimer implementation and SIGALRM handlingRon Yorston2-133/+1
Commit 69f49ea imported a setitimer implementation from git. Since setitimer isn't used at all in BusyBox it can be removed. The same technique could be used to implement alarm but nothing in the WIN32 port uses that (yet).
2015-07-17winansi: fixes to cursor positioning, screen clearingRon Yorston1-4/+15
It seems that the cursor positioning escape sequence 'ESC[n;mH' allows n and m values of 0 or 1 to represent the leftmost/topmost position. Allow for this and also fix handling of missing values. When the screen is cleared using FillConsoleOutputCharacterA it's also necessary to make explicit calls to FillConsoleOutputAttribute to reset attributes.

2015-07-14mingw: include unwind tables in 64-bit build by defaultRon Yorston1-1/+1
Add "-funwind-tables -fasynchronous-unwind-tables" to CFLAGS for the 64-bit build, overriding the usual default. Without this change setjmp/longjmp don't work.
2015-07-14ash: store pointers to be fixed as pointers, not intRon Yorston1-14/+16
The data block passed during forkshell includes the nodeptr array of (internal) pointers to (other internal) pointers that need to be fixed. Store the pointers as pointers, not int.

Now that the only thing protected by setjmp/longjmp is the saved string, we can allocate it on the stack to get rid of the jump.

2015-07-13ash: remove parsebackquote flagRon Yorston3-7/+3
Commit 503a0b8 from git://git.kernel.org/pub/scm/utils/dash/dash.git by Herbert Xu says: >The parsebackquote flag is only used in a test where it always has the >value zero. So we can remove it altogether. The first statement is incorrect: parsebackquote is non-zero when backquotes (as opposed to $(...)) are used for command substitution. It is possible for the test to be executed with parsebackquote != 0 in that case. The test is question checks whether quotes have been closed, raising the error "unterminated quoted string" if they haven't. There seems to be no good reason to allow unclosed quotes within backquotes. Bash, hush and dash (after commit 503a0b8) all treat the following as an error: XX=`"pwd` whereas BusyBox ash doesn't. It just ignores the unclosed quote and executes pwd. So, parsebackquote should be removed but not for the reason stated. function old new delta parsebackquote 1 - -1 readtoken1 3222 3182 -40 ------------------------------------------------------------------------------ (add/remove: 0/1 grow/shrink: 0/1 up/down: 0/-41) Total: -41 bytes Signed-off-by: Ron Yorston <rmy@frippery.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2015-07-03Allow different ways to manipulate environment for XP vs 64-bitRon Yorston5-1/+1130
Commit fa147bd 'Use putenv to implement unsetenv/clearenv' allowed BusyBox to run on ReactOS but broke it on Windows XP so it was reverted. It turns out that the same change is required on 64-bit Windows. Reinstate the 'safe' environment manipulation code but make it a configuration option. Add a config file for 64-bit Windows that does the right thing.

In standalone shell mode search the applet table as well as PATH when tab completing a command. Use a stupid linear search: we're also about to read all the directories on PATH so efficiency isn't a big concern.

2015-06-05ash: add winxp optionRon Yorston2-6/+14
In some circumstances Windows XP and Windows Server 2003 seem to dislike environment variables with backslashes in paths. The 'winxp' option prevents BusyBox from changing backslashes to slashes in the environment. Although the option can be managed by the 'set' builtin it only works if '-X' is given as the first argument to the shell.
2015-06-02ash: skip PATH if executable and command are both busyboxRon Yorston1-0/+21
If the command is 'busybox' and the executable is 'busybox.exe' don't bother checking PATH, just run the executable. This means that busybox.exe can be somewhere other than on PATH.
2015-06-01mingw: add magic '--busybox' flagRon Yorston3-2/+7
If BusyBox is invoked with argv[1] set to --busybox skip the first two arguments so that argv[2] becomes the applet name and argv[3] et seq are its arguments. This is needed when BusyBox is run as sh.exe and the executable is reexecuted to invoke compress/decompress applets.

2015-05-27Enable seamless compression for WIN32Ron Yorston11-12/+82
In the archival code we pretend that WIN32 is a no-MMU platform and use the new mingw_popen_fd routine to pipe data to/from commands to compress/decompress. The pretence is maintained by redefining MMU macros in bb_archive.h. This is mostly used in the archival code but there are a handful of places where it's used to access public interfaces. The symbol BB_ARCHIVE_PUBLIC is defined in these places. With these changes: tar supports seamless compression/decompression rpm2cpio and dpkg-deb can be enabled
