2008-03-17remove alarm() calls which were functioning as a primitivePaul Fox
watchdog function, presumably to catch infinite loop bugs. (control-C can do the same thing, and the alarms were too short in any case.) also, switch to sigsetjmp/siglongjmp in order to allow repeated use of control-C -- otherwise it works once, then not again.

execution of commands supplied by -c or EXINIT, so their effect is displayed correctly.
2008-03-06fixed the "dot" (i.e. '.') command, to properly re-init itsPaul Fox
buffer between commands, not recalculate its length all the time, and to not reallocate its fixed-length buffer frequently. fixed the 'c', 'd', and 'y' commands to properly handle both motions that are just part of a line, and those that are multiline. for instance, now "c%" and "2cw" work correctly, whether the motions span lines or not. added some permissble motions for 'c', 'd', and 'y': namely 'h', 'l', SPACE, BS, and DEL
2008-03-05fix vi's '?' and '/' commands to correctly set a new directionPaul Fox
when reusing a previous search pattern. previously only 'n' and 'N' reversed directions properly.

2007-07-17vi: multiple fixes by Natanael Copa <natanael.copa@gmail.com>Denis Vlasenko
* the puzzling message on error is replaced with strerror(errno) so it should be even more detailed and smaller at the same time. * merged code in edit_file() and code for ':edit <file>' in colon() into new func init_text_buffer(). Was horribly duplicate. Moved most of error/sanity checking to file_insert(). Result is that you get a proper validation (prevent reading /dev/*) and error messages for ':r <file>' * renamed 'cfn' to 'current_filename' for improved readability * merged smallint vi_readonly and readonly into bitfields into readonly_mode to save space. * added text_size variable to keep track how big the text buffer is. This is used to fix a buffer overflow. To reproduce bug: ./busybox vi TODO :r Makefile vi segfaults due to no buffer checking is done at all. som redesign is needed here but i added a check in text_hole_make() to aviod the segfault at least. * removed isblnk() and use isblank(3) instead. * fixed compiler warning by displaying the return code for :!<command> This makes things bigger than needed but since the patch reduces the overall size... (see below) * new func next_tabstop(int) merges some duplicate code. There are more cuplicode here but i couldnt find a good way to merge them. * Fix *ANNOYING* placement of cursor on '\t' characters. To reproduce: echo -e "\thello" > file1 ./busybox vi file1 Try to insert some text at the beginning of line. Text will be inserted but cursor is blinking somewhere else. The patch should make busybox vi behave more like original vi(m). Costs a few bytes but its worth it imho. * new_text() is moved into init_text_buffer() * the previously added update_ro_status() was moved info file_insert due to duplication removal mentioned above. function old new delta init_text_buffer - 245 +245 file_insert 312 420 +108 next_tabstop - 82 +82 text_hole_make 154 171 +17 do_cmd 5093 5100 +7 static.cmd_mode_indicator - 5 +5 refresh 1248 1253 +5 current_filename - 4 +4 yank_delete 161 164 +3 what_reg 96 99 +3 end_cmd_q 78 81 +3 char_insert 440 442 +2 readonly_mode - 1 +1 vi_readonly 1 - -1 setops 154 153 -1 readonly 1 - -1 vi_setops 4 1 -3 string_insert 161 158 -3 cfn 4 - -4 show_status_line 532 514 -18 readit 519 500 -19 move_to_col 161 138 -23 vi_main 495 433 -62 isblnk 75 - -75 .rodata 4751 4655 -96 edit_file 892 787 -105 new_text 125 - -125 update_ro_status 131 - -131 colon 3848 3667 -181 ------------------------------------------------------------------------------ (add/remove: 5/6 grow/shrink: 8/10 up/down: 485/-848) Total: -363 bytes text data bss dec hex filename 34751 873 4260 39884 9bcc busybox_old 34439 877 4260 39576 9a98 busybox_unstripped
