1 - ptrace(2) syscall for native emulation
2 - common ptrace(2) syscall code (shared with compat_netbsd32)
3 - support routines that are shared with PROCFS and/or KTRACE
* Add module glue for #1 and #2. Both modules will be built-in to the
kernel if "options PTRACE" is included in the config file (this is
the default, defined in sys/conf/std).
* Mark the ptrace(2) syscall as modular in syscalls.master (generated
files will be committed shortly).
* Conditionalize all remaining portions of PTRACE code on a new kernel
option PTRACE_HOOKS.
XXX Instead of PROCFS depending on 'options PTRACE', we should probably
just add a procfs attribute to the sys/kern/sys_process.c file's
entry in files.kern, and add PROCFS to the "#if defineds" for
process_domem(). It's really confusing to have two different ways
of requiring this file.
Without this, an attempt to build a kernel with COMPAT_LINUX32 but without
COMPAT_NETBSD32 will fail during the execution of genassym, and the error
messages are not very helpful.
With this change, config(1) will automatically (and silently) select/add
COMPAT_NETBSD32 to the configuration. It might be better if config(1)
were to issue an appropriate diagnostic, but that is a change for some
future day.
if bigger then MAXPHYS
multiply the queue size by number of queues for ld(4) sc_maxqueuecnt, so
that ld_diskstart() would try to use full capacity, instead of throttling
to one queue worth of commands
For example if you do
$mkdir -p /tmp/dir1/dir2
Then:
$ls /tmp/di <TAB> auto completes to
$ls /tmp/dir1/
Hitting <TAB> again auto completes to
$ls /tmp/dir1/dir2
Whereas it should auto complete to
$ls /tmp/dir1/dir2/
Essentially, in cases like above where you have to hit <TAB> twice to get
to the match and there is only one match (because only one file/sub-directory) then
auto complete doesn't work correctly. It doesn't append a trailing slash (in case
of directory) or a space (in case of a file) to the match name.
I have tested file name completion in sh(1) and symbol completion in gdb after
this change.
