changelog-1996

cygwin, 著名的在win32下模拟unix操作系统的东东

Wed Oct 23 10:43:05 1996  Jeremy Allison <[e-mail]>

	* dcrt0.cc (api_fatal): Changed locking clear of
	process table to unlocking clear. Needed as lock code calls
	api_fatal.
	* exceptions.cc: Added debug_printfs to follow exceptions in
	strace mode.
	* pinfo.cc: Added code to ensure fd table is cleared when new
	pid entry allocated. Fixed bug when process is terminated
	violently by TerminateProcess and leaves fd table non-zero.
	* termios.cc: Changed stubbed out syscalls to syscall_printf
	rather than small_printf. Stops annoying tcdrain message.
	* winsup.h: Made get_empty_pinfo call private to pinfo_list.
	Should never be called external to this class.

Tue Oct 22 16:14:23 1996  Jeremy Allison <[e-mail]>

	* hinfo.cc: Removed previous change. This is not the
	correct place to flush input events.

Tue Oct 22 09:25:32 1996  Jeremy Allison <[e-mail]>

	* dcrt0.cc: Fixed up exit code to clean up pinfo array.
	* exceptions.cc: Fixed up exit code to clean up pinfo array.
	* fork.cc: Tidied up access to inuse_p entry. Added flags
	to allow different states to be represented.
	* hinfo.cc: Added code to flush pending events if
	stdin is a console.
	* pinfo.cc (pinfo::record_death): Added code to clean
	the pinfo array if we are an exiting parent.
	* spawn.cc: Removed erroneous code to clean childs
	pinfo entry.
	* wait.cc: Changed WAIT_ERROR_RC to Win32 WAIT_FAILED.
	Tidied up access to pinfo array.
	* winsup.h: Added record_death_nolock to pinfo class.
	Added PID_XXX types for inuse_p.

	windowsx.h, winerror.h, wingdi.h, winkernel.h, winnt.h,

        (3). All handles [written,not tested]. (4). Handles & sockets
        with timeout [not yet written,returns -1]. Correctly blocks
