| * less: fix display of line numbersRon Yorston2015-07-191-24/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Line numbers are displayed incorrectly on lines that have a search pattern highlighted. The problem can be fixed by moving the call to lineno_str in print_found above the while loop that alters the value of the line pointer. However, a more substantial rewrite results in savings. function old new delta buffer_print 688 697 +9 .rodata 156077 156045 -32 lineno_str 85 - -85 ------------------------------------------------------------------------------ (add/remove: 0/1 grow/shrink: 1/1 up/down: 9/-117) Total: -108 bytes Signed-off-by: Ron Yorston <rmy@frippery.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The -S flag, to cause long lines to be truncated, was enabled by FEATURE_LESS_DASHCMD. This is non-obvious and -S is useful even if the '-' command isn't enabled. function old new delta .rodata 156045 156077 +32 packed_usage 30223 30244 +21 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 53/0) Total: 53 bytes Signed-off-by: Ron Yorston <rmy@frippery.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* | ash: don't convert path delimiters for certain environment variablesRon Yorston2015-07-302-1/+7
| | | | | | | | | | | | | | The SYSTEMROOT and COMSPEC environment variables are known to cause problems for Windows applications if they contain forward slashes rather than backslashes. So don't convert them, even if the -X flag isn't present.
* | win32: remove setitimer implementation and SIGALRM handlingRon Yorston2015-07-262-133/+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).
* | winansi: fixes to cursor positioning, screen clearingRon Yorston2015-07-171-4/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * ash: remove parsebackquote flagRon Yorston2015-07-133-7/+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>

| | | | | | | | | | | | | | | | | | | | | | 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.

* | ash: add winxp optionRon Yorston2015-06-052-6/+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.
* | ash: skip PATH if executable and command are both busyboxRon Yorston2015-06-021-0/+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.
* | mingw: add magic '--busybox' flagRon Yorston2015-06-013-2/+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.
