vi: multiple fixes by Natanael Copa <natanael.copa@gmail.com>
...
* 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.
