* memset/memzero needs cstring/string.h (again)
* winsize_t requires an impl from <sys/termios.h>
With this patch, I was able to get fish master to build on Solaris 11.4
without any additional dependencies (after installing gcc 7, git, and
cmake). I think the ncurses dependency can be dropped from the
OpenIndiana package?
This was lost in
6bdbe732e40c2e325aa15fcf0f28ad0dedb3a551..c7160d7cb4970c2a03df34547f357721cb5e88db.
Note that we only print a term-support flog message for now, the
warning seems a bit much.
Fixes#7709.
Finish the transition to termsize.h. Remove the scary termsize bits
from common.cpp, which can throw off events at arbitrary calls and are
dangerously reentrant. Migrate everyone to the new termsize.h.
fish's handling of terminal sizes is currently rather twisted. The
essential problem is that the terminal size may change at any point from a
SIGWINCH, and common_get_{width,height} may modify it and post variable
change events from arbitrary locations.
Tighten up the semantics. Assign responsibility for managing the tty size
to a new class, `termsize_container_t`. Rationalize locking and reentrancy.
Explicitly nail down the relationship between $COLUMNS/$LINES and the tty
size. The new semantics are: whatever changed most recently takes
precendence.
