- Introduce two small helpers to change and restore the console title.
- Console title can change even when internal commands are executed.
- Note that when commands are run from within batch files, title is unchanged.
- When "cmd.exe /c command" is run, the console title is unchanged; however
when "cmd.exe /k command" is run, the console title changes.
(cherry picked from commit a165999067)
picked to fix CORE-14648 which was the last puzzle-piece to build ros on ros
This allows to break commands such as:
C:\ReactOS\system32> for %f in (*.*) do dir
as one would expect: stop the currently running 'dir' and the 'for'.
"bCtrlBreak" doesn't need to be volatile too.
Using CTRL-C to cancel command line input would leave the prompt in
a state where the next command would be ignored. For example:
dir<CTRL-C>
dir
would cause cmd.exe to ignore the second dir command.
CORE-11677
The standard Win32 Console Control Handler will give CTRL-C events to
processes spawned from cmd.exe. If cmd.exe calls GenerateConsolCtrlEvent()
then the child process will receive two CTRL-C events.
CORE-13974
This should fix situations where (for example):
command_1 | command_2 && echo Succeeded
should *NOT* run "echo Succeeded" if any of the command_1 or command_2 has
failed.
This also makes the ExecutePipeline() function on par with the other
"ExecuteXXX()" helpers.
Problem diagnosed by Doug Lyons; patch inspired by contributor 'cagey45'.
