Corinna Vinschen ae3370bb9d Cygwin: strace: print windows and cygwin pid in event output
strace only printed the Windows PID in event output so far.

Especially now that Windows and Cygwin PID are decoupled, the
strace user might like to see the Cygwin pid in event output as
well.  However, at process startup, the process might not have
a Cygwin PID yet.

To mitigate this, always print the Windows PID and only add the
Cygwin pid if it exists.

Corinna Vinschen 448cf5aa4b Cygwin: processes: fix handling of native Windows processes
Since commit b5e1003722, native
Windows processes not started by Cygwin processes don't have a
Cygwin PID anymore.  This breaks ps -W and kill -f <WINPID>.

Introduce MAX_PID (65536 for now).

Cygwin processes as well as native Windows processes started
from a Cygwin process get a PID < MAX_PID.  All other native
Windows processes get a faked Cygwin PID >= MAX_PID.

Peter Foley 0008bdea02 Refactor to avoid nonnull checks on "this" pointer.
G++ 6.0 asserts that the "this" pointer is non-null for member
functions.
Refactor methods that check if "this" is non-null to resolve this.

winsup/cygwin/ChangeLog:
external.cc (cygwin_internal): Check for a null pinfo before calling
cmdline.
fhandler_dsp.cc (Audio::blockSize): Make static.
fhandler_dsp.cc (Audio_in): add default_buf_info.
fhandler_dsp.cc (Audio_out): Ditto.
fhandler_dsp.cc (Audio_out::buf_info): Refactor method to call
default_buf_info if dev_ is null.
fhandler_dsp.cc (Audio_in::buf_info): Ditto.

Mark Geisert 5807ba83e4 Support profiling of multi-threaded apps.
This patch set modifies Cygwin's profiling support to sample PC values
of all an app's threads, not just the main thread. There is no change
to how profiling is requested: just compile and link the app with "-pg"
as usual. The profiling info is dumped into file gmon.out as always.

A new facility enabled via the environment variable GMON_OUT_PREFIX.
This facility is intended to match an undocumented Linux glibc feature.
Exporting the variable with a non-empty value such as "foo" causes the
profiling info to go to a file named foo.$pid instead of the default.
With that, both resulting processes of a fork() can have their profiling
data captured in separate files. gprof already knows how to accumulate
data from multiple files if they all pertain to the same app.

There is no change to the normal Cygwin execution paths if profiling is
not enabled. And when it is enabled, only the one profiling thread per
profiled app is doing more work than it used to.

	* include/sys/cygwin.h: Add CW_CYGHEAP_PROFTHR_ALL.
	* cygheap.cc (cygheap_profthr_all): New C-callable function that
	runs cygheap's threadlist handing each pthread's thread handle in

	* gmon.h (struct gmonparam): Make state decl volatile.
	* mcount.c (_MCOUNT_DECL): Change stores into gmonparam.state to use
	Interlocked operations. Add #include "winsup.h", update commentary.
	* profil.c (profthr_byhandle): New function abstracting out the
	updating of profile counters based on a thread handle.
	(profthr_func): Update to call profthr_byhandle() to sample the main
	thread then call cygheap_profthr_all() indirectly through
	cygwin_internal(CW_CYGHEAP_PROFTHR_ALL) to sample all other threads.
	(profile_off): Zero targthr to indicate profiling was turned off.
	(profile_on): Fix handle leak on failure path.
	(profile_child): New callback func to restart profiling in child
	process after a fork if the parent was being profiled.
	(profile_ctl): Call pthread_atfork() to set profile_child callback.
