winsup/cygwin : ChangeLog child_info.h dcrt0.cc fork.cc init.cc
miscfuncs.cc ntdll.h thread.cc wincap.cc
wincap.h
Log message:
* child_info.h (CURR_CHILD_INFO_MAGIC): Update.
(class child_info_fork): Remove stacksize, add stackaddr and guardsize
members.
* dcrt0.cc (child_info_fork::alloc_stack_hard_way): Partial rewrite
to regenerate the stack exactly as in the parent.
(child_info_fork::alloc_stack): Set stackaddr to 0, rather than
stacksize.
(dll_crt0_1): Check for stackaddr before changing the stack addresses
in the TEB.
* fork.cc (frok::child): Check for stackaddr here.
(frok::parent): Set ch.stackaddr and ch.guardsize if not called from
the main thread.
* init.cc (dll_entry): Replace pointer to NT_TIB with pointer to TEB.
Fix incorrectly changed address test before removing _my_tls.
Set StackLimit to NULL on Windows 2000. Explain why.
* miscfuncs.cc (struct thread_wrapper_arg): Store stackbase rather
than stacksize, store commitaddr, remove guardsize. Store all pointers
as char * for easier address arithmetic.
(thread_wrapper): Rewrite to remove OS stack before calling thread
function. Add lots of comments to explain what we do.
(CygwinCreateThread): Reserve our own stack in case we got no
application stack. Add comments.
* ntdll.h (struct _TEB): Extend defintion up to DeallocationStack
member.
* thread.cc (pthread_attr::pthread_attr): Use "(size_t) -1"
rather then 0xffffffff.
* wincap.h (wincaps::has_stack_size_param_is_a_reservation): New
element.
* wincap.cc: Implement above element throughout.
