Some calculation show that with the current setup there will not be enough bytes
occupied for that, barring the case of malicious translation. Still should be
possible to have array overrun with specially crafted translation.
1. Don't check elapsed time in children_kill_cb(), it's already implied
by the start-time of the timer itself.
2. Restart timer from children_kill_cb() for PTY jobs, to send SIGKILL
after SIGTERM. There is an edge case where SIGKILL might follow
SIGTERM too quickly, if jobstop() is called near the 2-second timer
window. But this edge case is not worth code complication.
Before f31c26f1af the timer was used to try SIGTERM *and* SIGKILL, so
a repeating timer was needed. After f31c26f1af process_stop() sends
SIGTERM immediately, and the timer only sends SIGKILL.
So we don't need a repeating timer.
- Simplifies the logic: don't need to call uv_timer_stop() explicitly.
- Avoids a problem: if process_stop() is called more than once in the
2-second window, the first on_process_exit() would call
uv_timer_stop() which stops the timer for all stopped processes.
children_kill_cb() is racey. One obvious problem is that
process_close_handles() is *queued* by on_process_exit(), so when
children_kill_cb() is invoked, the dead process might still be in the
`loop->children` list. If the OS already reclaimed the dead PID, Nvim
may try to SIGKILL it.
Avoid that by checking `proc->status`.
Vim doesn't have this problem because it doesn't attempt to kill
processes that ignored SIGTERM after a timeout.
closes#8269
I failed to deduce why analyzer thinks E882 may not be triggered, though
conditions for triggering it are strange: it would trigger E882 only in the
single case “function returned non-number”. Cases “function thrown exception”,
or “built-in sorter encountered error” will neither yield E882 nor stop
sort()/uniq().
Note though that searching test code revealed that neither E702 nor E882 are not
tested anywhere.
Fixes#6890 by reading from the Windows console input buffer after
stdin has been closed.
Vim defines HAVE_DUP for Windows and does the close-dup dance[1]:
close(0);
dup(2);
which always fails, then falls back to reading from the Windows console
input buffer[2].

* Reading from stdin on Windows is fixed in the same way as it was in
#8267.
* The file_read function was returning without filling the
destination buffer when it was called with a non-blocking file
descriptor.
It's only appropriate to set CMAKE_MAKE_PROGRAM to gmake when we're
using the "Unix Makefiles" generator. On QB, the nodes have Ninja
available and will use it, which means CMAKE_GENERATOR is set to
"Ninja". Setting CMAKE_MAKE_PROGRAM was forcing the build to use gmake
instead of ninja, which was causing the build failure.
This fixes an issue with compiles failing in release mode due to shape
having the possibility of being used uninitialized (since the default
case was missing).
Any user can create a directory on root.
Creating a directory on root allows any user to write files within that directory.
Test_recover_root_dir() passes when run locally as a regular user (not admin).
Unset $SHELL so that child nvim use cmd.exe as default shell.
Unset $TERM so that child nvim don't segfault with negative exit code.
sh/bash use TERM=cygwin by default if it is unset.
mintty sets TERM to xterm.
