isn't enabled.
This is how the rc.d system works in conjunction with our current build
and install system; all the rc.d scripts are installed even if the
subsystems they control are not.
XXX: Should (for example) 1024 be 1.0K or 1K when the HN_DECIMAL flag
is passed? Should there be a separate option that says "use the
HN_DECIMAL behaviour unless we are exactly equal to the suffix"?
Init progress bar step/position in ProgressBar::create.
Specify WS_EX_CLIENTEDGE style for the progress bar, an empty gray
area between the buttons looks stupid. With 3d edge a user has a hint
there's a progress bar there. While here, make it PBS_SMOOTH, it
looks nicer that way.
remote process. This new implementation also passes all the test programs
I've written so far.
- When exceptions come from traps, no UNIX signal should evet be sent.
- Add a lock to ensure a debugger handles only one exception at a time
- Use a structure to hold flavor and behavior in exception ports, instead
of stuffing the two argument into an int.
- Implement new Mach services: thread_suspend, thread_resume and thread_abort
- Implement Darwin's ptrace PT_ATTACHEXC and PT_THUPDATE commands
- Handle NULL second argument correctly in sigprocmask.
- One mistake in the last commit (darwin_tracesig prototype)
fit what it does.
The softsignal feature is used in Darwin to trace processes. When the
traced process gets a signal, this raises an exception. The debugger will
receive the exception message, use ptrace with PT_THUPDATE to pass the
signal to the child or discard it, and then it will send a reply to the
exception message, to resume the child.
With the hook at the beginnng of kpsignal2, we are in the context of the
signal sender, which can be the kill(1) command, for instance. We cannot
afford to sleep until the debugger tells us if the signal should be
delivered or not.
Therefore, the hook to generate the Mach exception must be in the traced
process context. That was we can sleep awaiting for the debugger opinion
about the signal, this is not a problem. The hook is hence located into
issignal, at the place where normally SIGCHILD is sent to the debugger,
whereas the traced process is stopped. If the hook returns 0, we bypass
thoses operations, the Mach exception mecanism will take care of notifying
the debugger (through a Mach exception), and stop the faulting thread.
buttons. Since there are 11 calls to menu.progress() in hpcboot, set
the progress bar range to 0..11, not 0..12.
In RootWindow::WMCreate - when we mean to adjust the top of the client
are by the button height, use _button_height, instead of cmdbar_height
(they now happen to be equal).
