cygwin : ChangeLog child_info.h cygheap.cc cygheap.h
dcrt0.cc exceptions.cc sigproc.cc thread.cc
thread.h spawn.cc
Log message:
* child_info.h (cygheap_exec_info::sigmask): Declare new field.
* cygheap.cc (init_cygheap::find_tls): Rename threadlist_ix -> ix. Only take
one pass through thread list, looking for eligible threads to signal. Set a
new param indicating that function has found a sigwait* mask.
* cygheap.h (init_cygheap::find_tls): Reflect new parameter.
* dcrt0.cc (parent_sigmask): New variable.
(child_info_spawn::handle_spawn): Save parent's signal mask here.
(dll_crt0_1): Restore parent's signal mask to tls sigmask as appropriate. Call
sig_dispatch_pending to flush signal queue when we can finally do something
with signals.
* exceptions.cc (sigpacket::process): Avoid attempting to handle signals if we
haven't finished initializing. Rely on the fact that find_tls will do mask
checking and don't do it again. Delete ill-named 'dummy' variable.
* sigproc.cc (cygheap_exec_info::alloc): Save calling thread's signal mask in
new sigmask field.
(wait_sig): Try to debug when WFSO fails and DEBUGGING is defined.
* thread.cc (pthread::set_tls_self_pointer): Make this a true automatic method
rather than inexplicably relying on a thread parameter.
(pthread::thread_init_wrapper): Accommodate set_tls_self_pointer change to
non-static. Initialize sigmask before setting tid or suffer signal races.
* ehread.h (pthread::set_tls_self_pointer): Make non-static, delete parameter.
