Note: Clint was failing because of recommending not to use long. But
converting to long is the proper refactoring here, in as far as other
longs exist. We could, then, disable clint rule, or remove this file
from checking. We choose the former, as it's being discussed what to do
with longs, but a decision has not been taken. So, it seems most
reasonable to allow longs for now, to enable proper refactorings, and
then, when a decision is taken, refactor all longs to some other thing.
- Add xterm/iterm sequences for changing cursor shape(with tmux wrapping).
Enabled by setting the NVIM_TUI_ENABLE_CURSOR_SHAPE environment variable.
- Remove nvim_override parameter from unibi_out. In the future another way of
overriding the terminal strings will be added.
- The syntax `gui=` is invalid when setting properties of highlight group.
- Wait for the initial "-- More --" prompt before continuing. Required to avoid
a race condition
- Remove abstract_ui global, now it is always active
- Remove some terminal handling code
- Remove unused functions
- Remove HAVE_TGETENT/TERMINFO/TERMIOS/IOCTL #ifdefs
- Remove tgetent/terminfo from version.c
- Remove curses/terminfo dependencies
- Only start/stop termcap when starting/exiting the program
- msg_use_printf will return true if there are no attached UIs(
messages will be written to stdout)
- Remove `ex_winpos`(implement `:winpos` with `ex_ni`)
The input buffer is only used for data that really came from another process and
is only visible to os/input.c. Remove the input_buffer_{save,restore} functions,
they are not necessary(Also can result in problems if data comes while the
typeahead is saved).
Some screen tests such as system/ctrl+c(viml_system_spec.lua) can take some time
to respond(default kill timeout is 2 seconds for an interrupted job) and fail
when running under a slow environment such as travis.
The `system` function is never executed with these tests because the ctrl+c is
queued with the input string that calls it(The `process_interrupts` function
will destroy all previous input when a ctrl+c is found).
Problem : Out-of-bounds access @ 5815.
Diagnostic : False positive.
Rationale : Error occurs when event_name2nr() returns NUM_EVENTS, which
means an event with that name was not found. That cannot
happen, as previous check using find_end_event() @ 5744
ensures event name exists.
Resolution : Assert event_name2nr() result is less thatn NUM_EVENTS.
Problem : Read from pointer after free @ {242, 391}.
Diagnostic : Real issues.
Rationale : Channel gets indeed freed on error case, producing
incorrect accesses to freed pointer later on.
Resolution : Implement reference counting mechanism to know when to free
channel.
Problem : Resource leak @ 3324.
Diagnostic : Real issue.
Rationale : Stack is not being freed on error cases.
Resolution : Free stack before invoking EMSG_RET_NULL.
