|
|
patch from cgf@bbc.com (Chris Faylor):
|
||
|
|
* sigproc.cc (proc_subproc): Remove over-enthusiastic test for

|
|
handle a dying subprocess when signal handlers are not ready.
|
||
|
|

|
||
|
|
returns.

|
|
|

|

|
Wed Dec 10 00:05:23 1997 Geoffrey Noer <noer@cygnus.com>
|
||
|
|
|
||
|
|
patch from cgf@bbc.com (Chris Faylor):
|
||
|
|
* dcrt0.cc (dll_crt0_1): Move start time initialization to a more
|
||
|
|
logical place (pinfo_init).
|
||
|
|
(do_exit): Reorganize to attempt to solve races when a cygwin
|
||
|
|
process occupies two windows pids (i.e., an execed process).
|
||
|
|
* exceptions.cc (lock_cs): Fix erroneous WFSO logic.
|
||
|
|
(sighandle): Use new method for determining if process was
|
||
|
|
initiated via fork.
|
||
|
|
(events_terminate): Do not close pinfo_mutex. Allow automatic
|
||
|
|
close by ExitProcess to lengthen the time that the pinfo structure
|
||
|
|
is locked, minimizing races between an exiting child and a
|
||
|
|
potentially exiting parent.
|
||
|
|
* hinfo.cc (hmap_init): Use new method for determining if process
|
||
|
|
was initiated via fork.
|
||
|
|
(hinfo_vec::de_linearize_fd_array): Fix a typo in a comment.
|
||
|
|
* pinfo.cc (clearout): Remove this function. Handled in
|
||
|
|
allocate_pid.
|
||
|
|
(pinfo_init): Move start_time setting here from dll_crt0_1.
|
||
|
|
Remove call to init_self in favor of adding three additional lines
|
||
|
|
of code.
|
||
|
|
(pinfo_list::operator []): Implement a very simple hashing
|
||
|
|
scheme for pid lookup.
|
||
|
|
(lpfu): New routine controlled by DEBUGGING conditional. When
|
||
|
|
DEBUGGING is activated, lpfu returns more information about the
|
||
|
|
state of a timed out pinfo_mutex.
|
||
|
|
(pinfo_list::get_empty_pinfo): Remove function. Move
|
||
|
|
functionality to allocate_pid.
|
||
|
|
(allocate_pid): Implement a (very) simple hashing scheme for
|
||
|
|
finding an available pid. Take advantage of reorganized pinfo
|
||
|
|
structure to zero all pertinent fields with one memset.
|
||
|
|
(pinfo::record_death_nolock): Don't bothering zeroing
|
||
|
|
inconsequential stuff.
|
||
|
|
(pinfo::record_death): Leave pinfo_mutex locked with the
|
||
|
|
understanding that this function will be called just prior to
|
||
|
|
exiting the process. This minimizes a race between a child which
|
||
|
|
is exiting at nearly the same time as its parent.
|
||
|
|
* sigproc.cc: Reformat function calls.
|
||
|
|
(sigproc_init): Clear new PID_INITIALIZING flag to indicate that
|
||
|
|
a (possibly execed) process is now capable of receiving signals.
|
||
|
|
(sig_send): Be more defensive in determining if a signal can be
|
||
|
|
sent to myself or suffer problems with execed processes.
|
||
|
|
(sigproc_terminate): Wait for sig_proc to exit to ensure that
|
||
|
|
all pending signals have been handled. Use new 'proc_terminate'
|
||
|
|
function to terminate the subprocess handling thread.
|
||
|
|
(allow_sig_dispatch): Don't bother blocking signals if signal
|
||
|
|
handling isn't active in this process yet.
|
||
|
|
(block_sig_dispatch): Don't bother blocking signals if signal
|
||
|
|
handling isn't active in this process yet.
|
||
|
|
(sig_proc): Use sig_loop_wait variable to control wait time for
|
||
|
|
signal semaphores. Uncouples this wait from wait_subproc.
|
||
|
|
Perform signal cleanup here on thread termination.
|
||
|
|
(proc_exists): More accurate tests to determine if a process
|
||
|
|
really exists.
|
||
|
|
(proc_register): Remove this function in favor of a macro.
|
||
|
|
(proc_subproc): More stringent test for being "ready" to process
|
||
|
|
subprocesses. Add more common initialization to PROC_ADDCHILD.
|
||
|
|
Remove PROC_EXIT in favor of a separate function.
|
||
|
|
(proc_terminate): New function. Replaces PROC_EXIT functionality
|
||
|
|
in proc_subproc. Terminates subproc handler thread.
|
||
|
|
(stopped_or_terminated): use lock_pinfo_for_update when modifying
|
||
|
|
child stopsig status or suffer a race.
|
||
|
|
(wait_subproc): Save sig_proc thread handle away for
|
||
|
|
synchronization when exiting. Set up 'i_am_alive' mutex inherited
|
||
|
|
by childen. Child's inability to lock this mutex means that the
|
||
|
|
parent is still alive and processing children. Use proc_loop_wait
|
||
|
|
to control WFMO. Clean up events queue on thread exit.
|
||
|
|
(zap_subproc): Clear out pinfo structure for a child.
|
||
|
|
* sigproc.h: Remove PROC_EXIT constant. Remove obsolete
|
||
|
|
proc_register declaration.
|
||
|
|
(alive_parent): New macro to determine if a parent is still alive.
|
||
|
|
* spawn.cc (spawn_guts): Fix a comment typo. Use proc_terminate
|
||
|
|
to terminate all subprocess handling prior to an exec. Use new
|
||
|
|
method for determining if this process was started via a fork.
|
||
|
|
Attempt to clean up races between execed process, its parent, and
|
||
|
|
the execed child.
|
||
|
|
* winsup.h (pinfo): Add a new handle indicating that a parent is
|
||
|
|
alive. This should be a foolproof way of determining if a parent
|
||
|
|
has gone away so that a child will know whether to remove itself
|
||
|
|
from the pinfo table.
|
||
|
|
Reorganize the structure in such a way that items to be zeroed
|
||
|
|
are grouped together at the beginning for more efficient zeroing
|
||
|
|
in allocate_pid.
|
||
|
|
Add a new PID_* constant.
|
||
|
|
New lock_pinfo_for_update macro for use when debugging cygwin.
|
||
|
|
|
||
|
|
Wed Dec 10 00:05:23 1997 Geoffrey Noer <noer@cygnus.com>
|
||
|
|
|
||
|
|
patch from sos@prospect.com.ru (Sergey Okhapkin):
|
||
|
|
Change the way to inherit fd table on spawn/exec calls.
|
||
|
|
Use STARTUPINFO structure to pass an fd table to a child process
|
||
|
|
instead of shared memory area. This is undocumented, but is used
|
||
|
|
by MSVC runtime. The desktop inheritance code added again,
|
||
|
|
otherwise user32.dll will fail to initialize after sexec calls.
|
||
|
|
* pinfo.cc (pinfo_init): delinearize fd array from STARTUPINFO
|
||
|
|
structure instead of call to copy_shared_fd_table.
|
||
|
|
* shared.cc (create_shared_fd_mapping_name): remove
|
||
|
|
(create/copy_shared_fd_table): remove
|
||
|
|
* spawn.cc (spawn_guts): use lp(cb)Reserved2 fields of STARTUPINFO
|
||
|
|
to pass fd table to a child. Remove call to
|
||
|
|
create_shared_fd_table. Inherit window station/desktop on sexec
|
||
|
|
calls.
|
||
|
|
* winsup.h: remove prototypes for create/copy_shared_fd_table.

flags to handle blocking vs. non-blocking I/O. Should
|
||
|
|
initialize tty to standard state (9600 bits/sec - 8 - 1 with
|
||
|
|
no flow control) but this code needs more work still. Ifdef
|

|

|
||
|
|
a DCB struct to hold the values we will set. First call
|
||
|
|
GetCommState to get the current state, then reassign values
|
||
|
|
based on the contents of the termios struct. Handle the
|
||
|
|
case where t->c_ospeed is set to B0, otherwise set state.BaudRate.
|
||
|
|
Set all the other DCB struct values appropriately, based on
|
||
|
|
the contents of the termios struct.
|
||
|
|
(fhandler_tty::tcgetattr): do the inverse of tcsetattr.
|
||
|
|
Call GetCommState to get the current state and use this to set
|
||
|
|
the appropriate termios struct values.
|
||
|

|
||
|
|
Add protos for tc* functions.

was possible when reparenting an exited process. Fix this.
|
||
|
|
* dcrt0.cc (do_exit): Only do minimal cleanup if "pid focus"
|
||
|
|
has moved to another windows process or the other process will
|
||
|
|
become confused.
|
||
|
|
|

|
|
patch from sos@prospect.com.ru (Sergey Okhapkin):
|
||
|
|
* sigproc.cc (getsem): set errno to EPERM if existing semaphore
|
||
|
|
cannot be opened.
|
||
|
|
(wait_subproc): allow access to signal semaphores to process's
|
||
|
|
owner only except for SIGCHLD (needed for SIGCHLD delivery after
|

|
|
sexecXX calls).

patch from cgf@bbc.com (Chris Faylor):
|
||
|
|
* syscalls.cc (hash_path_name): Ignore trailing backslash when
|
||
|
|
calculating pathname hash.
|
||
|
|
* hinfo.cc (hinfo_vec::de_linearize_fd_array): Set use_tty
|
||
|
|
if /dev/ttyn is detected in the shared_fd_table. Before this
|
||
|
|
change, executing "set CYGWIN_TTY=1", "bash", "unset CYGWIN_TTY",
|
||
|
|
"/bin/pwd" would result in pwd printing nothing because
|
||
|
|
the de_linearize code would use the wrong fhandler_xxx when
|
||
|
|
reading from the buffer inherited from the parent process.
|
||
|
|
* cygwin.din: Add new ctermid function for export.
|
||
|
|
* syscalls.cc (ctermid): New function
|
||
|
|
* exceptions.cc (call_handler): If called during a P_OVERLAY
|
||
|
|
spawn, merely set appropriate flags and return. The spawn
|
||
|
|
code will then clean up and exit.
|
||
|
|
* sigproc.cc (proc_exists): Reorganize to better detect defunct
|
||
|
|
processes. Don't clean up pinfo if process has a parent since the
|
||
|
|
parent should clean up eventually.
|
||
|
|
* spawn.cc: New global exec_exit. Set by signal handler to
|
||
|
|
value which should be used on exit from aborted spawn.
|
||
|
|
(spawn_guts): Try harder to let the child terminate (if it is
|
||
|
|
going to) before exiting on a signal. Remove obsolete code.
|
||
|
|
|
||
|
|
patch from sos@prospect.com.ru (Sergey Okhapkin):
|
||
|
|
* exec.cc (file_exists): Removed
|
||
|
|
* spawn.cc (spawn_guts): call perhaps_suffix to convert filename
|
||
|
|
to win32 form and to check file existance; prog variable
|
||
|
|
removed, all references changed to real_path variable.
|
||
|
|
Do not inherit parent's window station/desktop on sexecXX calls.
|
||
|
|
They are no longer needed with the new signal handling.
|
||
|
|
(_spawnve): extra file existance check removed
|
||
|
|
* winsup.h: file_exists prototype removed

replaced with path_conv class calls.
|
||
|
|
* path.cc (path_conv::path_conv): comments added, O_NOSYMLINK case

added.
|
||
|
|
* path.h (class path_conv): symlink_p, exec_p - new class members.

|
|
|

|
|
patch from cgf@bbc.com (Chris Faylor):
|
||
|
|
* dcrt0.cc (do_exit): Use new pinfo element in debug statement.
|
||
|
|
* pinfo.cc (pinfo_init): Eliminate use of "PID" environment
|
||
|
|
variable in favor of scanning the process table for a
|
||
|
|
SpawnedProcessId field matching current windows process id.
|
||
|
|
Should speed up spawned process startup slightly. Delay setting
|
||
|
|
of dwProcessId until process is capable of processing signals
|
||
|
|
since this field is used to build signal semaphores.
|
||
|
|
* signal.cc (kill_worker): Perform a `proc_exists' on the pid
|
||
|
|
in question if signal == 0. This will verify that the process
|
||
|
|
actually exists and was not abnormally terminated.
|
||
|
|
* sigproc.cc (sigproc_init): Initialize dwProcessId field after
|
||
|
|
signal processing has been initialized.
|
||
|
|
(sigproc_terminate): Remove events[0] close.
|
||
|
|
(getsem): Use GetCurrentProcessId to find the windows pid since
|
||
|
|
this dwProcessId field is not yet set up. Use proc_exists to
|
||
|
|
determine if error should be printed on OpenSemaphore error.
|
||
|
|
(proc_exists): New function. Makes more exhaustive test of
|
||
|
|
process existence. Determines if process died without going
|
||
|
|
through normal shutdown.
|
||
|
|
(wait_subproc): Close wakeup event only on thread exit.
|
||
|
|
* spawn.cc: Remove pExeced. Use new field in pinfo.
|
||
|
|
(spawn_guts): Initialize dwSpawnedProcessId field.
|
||
|
|
* utils/ps.cc (main): Perform a kill(pid, 0) on any pids that
|
||
|
|
appear to be active. This will clear out pids that have died
|
||
|
|
abnormally. 'ps -f' bypasses this.
|
||
|
|
* winsup.h (class pinfo): Add dwSpawnedProcessId field.

check, set subproc_ready event only if the process is exec'ed.
|
||
|
|
* spawn.cc (spawn_guts): initialize hProcess and dwProcessId

patch from cgf@bbc.com (Chris Faylor):
|

|
|
* dcrt0.cc (do_exit): Use EXIT_* flags to determine how exit

should proceed. Honor new EXIT_NOCLOSEALL to avoid

close_all_files.
|

EXIT_SIGNAL define to indicate exiting due to signal.

|
|
* signal.cc (sigprocmask): Slightly more defensive check against

|
|
(_raise): Defensive check to guard against being called prior to

|
|
* fhandler.h (class fhandler_socket): destructor prototype added.
|
||
|
|
* fork.cc (cygwin_fork_helper1): set PID_SOCKETS_USED in the

|
|
child's pinfo if parent has open socket descriptors; call
|
||
|
|
winsock_init in child code if necessary.
|

* net.cc: static variable winsock_init_p removed;
|
||
|
|
number_of_sockets is new global variable containing number of

opened sockets.
|

(winsock_init): made global, save "winsock inited" flag in process
|

state field.

(cygwin32_winsock calls): condition for winsock initialisation
|

|
||
|

||
|
|
|

|
|
patch from cgf@bbc.com (Chris Faylor):
|
||
|
|
* exceptions.cc: Substitute do_exit for _exit as appropriate.
|
||
|
|
do_exit allows full 32 bits of exit value. The upper 16 bits
|
||
|
|
are used for special cygwin operations.
|
||
|
|
* winsup.h: Change definition of do_exit to allow calling from
|
||
|
|
signal handler.
|
||
|
|
* dcrt0.cc (do_exit): Change to allow calling from signal handler
|
||
|
|
in place of _exit. This is necessary to ensure that only cygwin
|
||
|
|
internal applications can exit with the upper order 16 bits set
|
||
|
|
to non-zero.

Wed Nov 12 23:02:34 1997 Geoffrey Noer <noer@cygnus.com>
|
||
|
|
|
||
|
|
patch from cgf@bbc.com (Chris Faylor):
|
||
|
|
* dcrt0.cc (do_exit): New function. Subsumes functionality of
|
||
|
|
_exit but takes a DWORD argument. Changed to avoid some shutdown
|
||
|
|
activities when called with REPARENTING bit set in argument. Also
|
||
|
|
explicitly kills any executing non-cygwin subprocess from a
|
||
|
|
spawn(P_OVERLAY)...
|
||
|
|
(_exit): Use do_exit for exiting. Ensure that only low order 1
|
||
|
|
bits of status are used or confusion will result if exiting with
|
||
|
|
some higher order bits set.
|
||
|
|
* exceptions.cc (set_process_mask): Reflect new method for
|
||
|
|
sig_send to send signals to self.
|
||
|
|
(handle_sigsuspend): Reflect new method for sig_send to send
|
||
|
|
signals to self.
|
||
|
|
* fork.cc: A handle name was changed in the pinfo structure to
|
||
|
|
be more reflective of its use. Change forkee_stopped to
|
||
|
|
subproc_ready everywhere.
|
||
|
|
* pinfo.cc (pinfo::clearout): Change forkee_stopped to
|
||
|
|
subproc_ready.
|
||
|
|
(pinfo_init): Use PID_EXECED flag to determine if this process has
|
||
|
|
been execed. If so, signal the remaining stub in the process
|
||
|
|
which invoked us so that the stub can terminate and let us take
|
||
|
|
over as this pid.
|
||
|
|
* sigproc.cc (sig_send): Change method for determining if sending
|
||
|
|
signals to myself. A NULL pointer means communicate with my
|
||
|
|
signal handler. This is necessary to allow communication with
|
||
|
|
our own signal processors after reparenting an execed process.
|
||
|
|
Also, add an additional test to detect if a process goes away in
|
||
|
|
the middle of attempting to send it a signal.
|
||
|
|
(allow_sig_dispatch): Reflect new method for sig_send to send
|
||
|
|
signals to self.
|
||
|
|
(getsem): Use dwProcessId in names for signal semaphores. Allows
|
||
|
|
communicating with both parts of a process that is temporarily
|
||
|
|
"split in two" while execing.
|
||
|
|
(sig_proc): Avoid printing an error if WAIT_FAILED and exiting
|
||
|
|
anyway. Process requests even if loop_wait == 0.
|
||
|
|
(proc_subproc): Defensive check for manipulating processes prior
|
||
|
|
to initialization or after terminating sigproc.
|
||
|
|
Use different check for subprocesses that have been reparented.
|
||
|
|
Hopefully this will eliminate WFSO, error 6 problems.
|
||
|
|
(wait_subproc): Only exit when loop_wait == 0 and not dealing with
|
||
|
|
a process.
|
||
|
|
* spawn.cc: Set up two global variables, used on exit when
|
||
|
|
execing a non-cygwin process: hExeced - handle of non-cygwin
|
||
|
|
process which is being waited for by a stub, pExeced - windows pid
|
||
|
|
of the process.
|
||
|
|
(spawn_guts): Reorganize to always (temporarily) wait for the new
|
||
|
|
process when P_OVERLAY. If a cygwin process is invoked, then the
|
||
|
|
wait will return when an event is signalled and the new process
|
||
|
|
will be "reparented" in the ppid. If a non-cygwin process is
|
||
|
|
invoked, wait until the process exits or a signal is received
|
||
|
|
which terminates the process. In this case, the do_exit function
|
||
|
|
will terminate the non-cygwin process.
|
||
|
|
* winsup.h: Rename forkee_stopped to subproc_ready since this
|
||
|
|
event now has a dual role which is better defined by this new
|
||
|
|
name. Add a new flag (PID_EXECED) for process_state. Define a
|
||
|
|
new function `do_exit' which operates similarly to _exit
|
||
|
|
but takes > 16 quantities with the high order bit signifying
|
||
|
|
different exit actions.

|
||
|
|
A time from today shows as HH:MM, times from previous days just
|

Sun Nov 9 17:08:30 1997 Geoffrey Noer <noer@cygnus.com>
|
||
|
|
|
||
|
|
* include/limits.h: define PATH_MAX here instead of
|
||
|
|
include/sys/param.h, define _POSIX_NGROUPS_MAX as 0 not 1
|
||
|
|
(system invariant value, not implementation-specific)
|
||
|
|
* include/sys/param.h: remove PATH_MAX, change NOFILE from 64
|
||
|
|
to 8192, delete PATHSIZE, remove safety wrapper around
|
||
|
|
MAXHOSTNAMELEN, add comments
|
||
|
|
* sysconf.cc (sysconf): return NGROUPS_MAX not zero,
|
||
|
|
return _POSIX_SAVED_IDS not zero. Return _POSIX_CHILD_MAX
|
||
|
|
not 4096. Return _POSIX_CHILD_MAX, not 8.
|
||
|
|
|
||
|
|
patch from sos@prospect.com.ru (Sergey Okhapkin):

|
||
|
|
and NOFILE_INCR
|
||
|
|
* hinfo.cc (hmap_init, hinfo_vec::find_unused_handle): change to
|
||
|
|
support virtually unlimited numbers of fds. Remove setdtablesize
|
||
|
|
proto
|
||
|
|
* syscalls.cc: initialize dtable_size to NOFILE_INIT instead of

|

|
|
|

* exceptions.cc (__cygwin32_exception_handler): don't
|
||
|

print "In cygwin32_except_handler" for exceptions Cygwin32
|
||
|
|
isn't going to handle. Print "(progname PID) Exception: <type>"
|
||
|
|
to console. Redirect all detailed information including the
|
||
|
|
stack trace to <progname>.core. This should reduce confusion
|
||
|
|
about what's causing the exception (a lot of people would see "In
|
||
|
|
cygwin32..." and think the problem was in Cygwin32 when most of
|

|
|
the time it was in some other program).

patch from cgf@bbc.com (Chris Faylor):

|
|
Wed Nov 5 19:23:10 1997 Geoffrey Noer <noer@cygnus.com>
|
||
|
|
|
||
|
|
* drct0.cc (dll_crt0_1): stop initializing winsock on process
|
||
|
|
startup since that slows down startup time of all processes, even
|
||
|
|
ones that don't end up making Winsock calls.
|
||
|
|
* fork.cc (cygwin_fork_helper1): don't need to call uinfo_init
|
||
|
|
or socket_checkinit after fork -- the appropriate functions will
|
||
|
|
do the necessary initialization if they are ever called.
|
||
|
|
* net.cc: init winsock_init_p to zero and make it static
|
||
|
|
(all exported functions): call winsock_init before making
|
||
|
|
any WinSock calls since this no longer happens in dcrt0.cc
|
||
|
|
startup code. Only do this if !winsock_init_p.
|
||
|
|
(winsock_init): checkinit renamed. Now just inits winsock
|
||
|
|
without checking whether it has been already initialized.
|
||
|
|
Make it static.
|
||
|
|
* uinfo.cc (uinfo_init): after we call getpwnam, we know
|
||
|
|
the passwd file has been read in so don't check initialization
|
||
|
|
of it. However, we do need to read_etc_group() if group_in_memory
|
||
|
|
isn't set.
|
||
|
|
* passwd.cc: rename global i variable to pw_pos, rename
|
||
|
|
passwd_in_memory to passwd_in_memory_p to match net.cc scheme.
|
||
|
|
Add comments.
|
||
|
|
(read_etc_passwd): make static
|
||
|
|
(various): make sure to read_etc_passwd() if passwd_in_memory
|
||
|
|
isn't set
|
||
|
|
* grp.cc: add comments, rename idx global to grp_pos,
|
||
|
|
rename group_in_memory to group_in_memory_p to match net.cc
|
||
|
|
scheme, group_in_memory_p no longer static (needs to be accessed
|
||
|
|
by uinfo_init)
|
||
|
|
* winsup.h: remove proto for socket_checkinit since that's
|
||
|
|
renamed and static within net.cc

||
|

|
|
|

|
|
patch from cgf@bbc.com (Chris Faylor):
|
||
|
|
* signal.cc (sigprocmask): Newer versions of gcc will call
|
||
|
|
sigprocmask when a builtin constructor is activated. If this
|
||
|
|
happens prior to the setup of u->self, then a NULL dereference
|
||
|
|
will occur. Guard against this.

equivalent debug_printf, add standards comments, reformat a little
|
||
|
|
(fhandler_socket::close): simplify handling of res
|

|
||
|
|
|
||
|
|
* times.cc (settimeofday): set ENOSYS instead of EPERM
|
||
|
|
since ENOSYS maps to "Function not implemented" which is the
|
||
|
|
case here.
|
||
|
|
* syscalls.cc (seterrno): on failure, set EACCES instead of EPERM
|
||
|
|
which is better for the unknown error case

|
patch from green@cygnus.com (Anthony Green):
|
||
|
|
* dcrt0.cc: new host_dependent_constants object with a global
|
||
|
|
instance of it which allows constants that are different in Win 95
|
||
|
|
and NT to be saved here instead of having forks in the code and
|
||
|
|
having to check the OS type each time. Add two constants for
|
||
|
|
fhandler, one for sharing attributes and one for upper word value
|
||
|
|
for locking files.
|
||
|
|
(dll_crt0_1): call host_dependent init function
|
||
|
|
* fhandler.cc (fhandler_base::open): use above object for
|
||
|
|
setting shared attributes
|
||
|
|
(fhandler_disk_file::lock): get upper word for locking from
|
||
|
|
host_dependent_constants
|
||
|
|
* winsup.h: define host_dependent_constants class and add extern
|

|

force read of /etc/passwd and /etc/group.
|
||
|
|
* spawn.cc: call getenv instead cygwin32_getenv

(spawn_guts): force read of /etc/passwd and /etc/group on sexec

|
|
|

Now that it is possible to use gdb using a stable
|
||
|
|
cygwin.dll to debug a program using a newer, potentially buggy
|
||
|
|
cygwin.dll, the strace mechanism will probably end up being
|
||
|
|
used more and more for debugging timing/race-condition bugs that
|
||
|
|
aren't easily exposed in a gdb session. The following changes
|
||
|
|
make the strace facility better for debugging timing issues by
|
||
|
|
storing the last few commands in a buffer instead of writing
|
||
|
|
to disk each function call.
|
||
|
|
|
||
|
|
patch from cgf@bbc.com (Chris Faylor):
|
||
|
|
* dcrt0.cc (dll_crt0_1): Change to strace_init call to take
|
||
|
|
an argument (for planned future registry changes).
|
||
|
|
(_exit): Call strace_dump when appropriate. Add a debugging
|
||
|
|
printf.
|
||
|
|
* include/sys/strace.h: Add _STRACE_CACHE, _STRACE_EXITDUMP,
|
||
|
|
strace_dump ().
|
||
|
|
* strace.c (strace_init): Allow hexadecimal, octal setting of
|
||
|
|
strace flags in environment variable. Handle new cache option.
|
||
|
|
(strace_printf): Display number of seconds from last message.
|
||
|
|
Handle _STRACE_CACHE.
|
||
|
|
(strace_dump): New function. Dump cached messages to disk.

Wed Oct 22 00:08:40 1997 Geoffrey Noer <noer@cygnus.com>
|
||
|
|
|

* net.cc: remove unused herror function in favor of
|
||
|
|
cygwin32_herror which is exported as herror
|
||
|
|
* include/netdb.h: we are now exporting the socket calls without
|
||
|
|
the cygwin32_ prefix so we don't need the nasty remapping in
|
||
|
|
header files
|
||
|
|
* include/arpa/inet.h: ditto

|
||
|
|
any processes waiting for signal notification success when the
|
||
|
|
process receiving the signal is terminating.
|
||
|
|
(wait_subproc): Report on errors when opening the
|
||
|
|
sync_proc_subproc mutex. Move initialization of events[0]
|
||
|
|
"wakeup" signal prior to wait_subproc_inited or risk a (miniscule)
|
||
|
|
chance for a reference to a NULL handle.
|

outside of this module.
|
||
|

|
||
|

||
|
|
new signal dispatch mutex.
|

||
|
|

|
||
|
|
Change to mark as suspended signals which would dispatch for which
|
||
|
|
the sig_dispatch mutex is unavailable. Use sigproc_printf where
|
||
|
|
appropriate.
|
||
|
|
(events_init): Remove application_stopped mutex made obsolete by
|
||
|
|
new sigproc handling.
|
||

|
|
||
|
|
* sysdef/i386/winserve.def: remove ancient version of cygwin.din
|
||

|

|
|
kbhit, _kbhit, __small_printf = small_printf__FPCce
|
||
|
|
* key.cc: remove. Similar functionality exists in ncurses
|
||
|
|
which can be compiled for Cygwin32
|
||
|
|
* console.cc (ScreenCols, ScreenGetCursor, ScreenSetCursor,
|
||
|
|
ScreenRows): delete and delete SCREEN_ROWS/COLS defines
|
||
|
|
* pold.c: remove old pipe-related code that's no longer used
|
||
|
|

* syscalls.cc: started to add comments including standards
|
||
|
|
information
|
||
|
|
(truncate): new
|
||
|
|
(ftruncate): length is an off_t, not a size_t. Add missing
|
||
|
|
return value to debug printf
|
||
|
|
* syscalls.h: ftruncate length is an off_t, add proto for truncate
|
||
|
|
|
||
|
|
patch from cgf@bbc.com (Chris Faylor):
|
||
|
|
* console.cc (fhandler_console::write): Recognize '@' as a valid
|
||
|
|
character to follow a '\e[' sequence or get 'Bad escape' errors.
|
||
|
|
|

|
||
|
|
|

|
|
Mon Oct 13 18:41:09 1997 Geoffrey Noer <noer@cygnus.com>
|
||
|
|
|
||
|
|
* cygwin.din: revert renaming of __assert since that's
|
||
|
|
actually what it's supposed to be called
|
||
|
|
* assert.cc: ditto
|
||
|
|
|
||
|
|
Fri Oct 10 19:25:49 1997 Tom Tromey <tromey@cygnus.com>
|

Fri Oct 10 17:50:12 1997 Ian Lance Taylor <ian@cygnus.com>
|

|
|
VOID is not defined
|
||
|
|
|
||
|
|
Thu Oct 9 00:46:40 1997 Geoffrey Noer <noer@cygnus.com>
|
||
|
|
|
||
|
|
* cygwin.din: remove all libgcc.a exports. They don't
|
||
|
|
belong here since libgcc.a doesn't really relate to the
|
||
|
|
purpose of cygwin.dll, and (to make things worse) the contents
|
||
|
|
change over time.
|
||
|
|
* assert.cc: rename __assert to __cygwin32_assert
|
||
|

|
||
|
|
|
||
|
|
patch from sos@prospect.com.ru (Sergey Okhapkin):
|
||
|
|
* dcrt0.cc (_exit): under Win 95, don't send SIGCHLD
|
||
|
|
unless special env variable is set. This works around a
|
||
|
|
problem where exiting a process can hang under Win 95.

|
|
Mon Oct 6 23:41:34 1997 Geoffrey Noer <noer@cygnus.com>

|
||
|
|
winsup/utils.
|
||
|

|
|
such that this is no longer necessary.

|
||
|
|
|

|
|

|
||
|
|
|
||
|
|
patch from sos@prospect.com.ru (Sergey Okhapkin):
|
||
|
|
* spawn.cc (spawn_guts): return child's PID on
|
||
|
|
spawn (_P_NOWAIT,...) instead of child's handle.
|
||
|
|
(cwait): rewritten as a wrapper to waitpid.
|

|
|
|
||
|
|
patch from cgf@bbc.com (Chris Faylor):
|
||
|
|
* dcrt0.cc: Remove obsolete call to fork_terminate.
|
||
|
|
* exceptions.cc: Respace, remove extraneous trailing whitespace.
|
||
|
|
Change critical section to mutex since there are supposedly
|
||
|
|
multi-processor problems with critical sections under NT.
|
||
|
|
Use "lock_cs" and "unlock_cs" macros to lock/unlock critical
|
||
|
|
regions.
|
||
|
|
(init_exceptions): Change critical section initialization to mutex
|
||
|
|
initialization.
|
||
|
|
(set_process_mask): Use locking macros to control access to
|
||
|
|
sig_mask.
|

|
|
(ctrl_c_handler): Use lock_cs/unlock_cs to control access.
|
||
|
|
(events_init): Use standard cygname function to create names for
|
||
|
|
shareable objects.
|
||
|
|
(events_init): Close cs mutex.
|
||
|
|
* fork.cc: Use event flags which are specific to the child being
|
||
|
|
forked. This prevents one process from prematurely activating
|
||
|
|
another. It also makes fork slightly more thread-safe.
|
||
|
|
(fork_init): Remove event initialization.
|
||
|
|
(fork_terminate): Remove function.
|
||
|
|
(cygwin_fork_helper1): Initialize events on a per-fork basis.
|
||
|
|
Events are inherited in child's pinfo structure.
|
||
|
|
Remove child->hThread initialization as it not needed. Use
|
||
|
|
pi.hThread where child->hThread is used.
|
||
|
|
Work around Windows 95 bug where a WaitForSingleObjects will
|
||
|
|
sometimes return ERROR_INVALID_HANDLE when it is resumed after
|
||
|
|
a suspend.
|
||
|
|
* pinfo.cc: Remove references to hThread field whereever it occurs.
|
||
|
|
* strace.cc: Use standard cygname function to create name for
|
||
|
|
strace_mutex. Prevents confusion between different .dll versions.
|
||
|
|
* wait.cc (wait_found): Remove reference to hThread.
|
||
|
|
* winsup.h (class pinfo): Remove reference to hThread. Add
|
||
|
|
per-process fork control event handles.
|
||
|
|
* include/limits.h: Increase NGROUPS_MAX from 0 to 1 to reflect
|
||
|
|
recent change to getgroups.

Revert patches to sources applied after Sept 16. Removed

|
|

|
||
|
|
|
||
|
|
Fixes for things that were causing compile-time warnings:
|

|
|
of execve in newlib which this calls.
|
||
|
|
(sexecve): add missing const to def
|
||
|
|
(sexeclpe): don't need to cast argv in sexecvpe call

|
|

|
|

|
||
|
|
|
||
|
|
patch from sos@prospect.com.ru (Sergey Okhapkin):
|
||
|
|
* dcrt0.cc (dll_crt0_1): don't use alloca for allocating storage

|
||
|
|
|
||
|
|
patch from cgf@bbc.com (Chris Faylor):
|
||
|
|
* Makefile.in (LD_STUFF): Add datestamp.o after DLL_OFILES.
|
||
|
|
(datestamp.o): New target. datestamp.c is generated whenever .o
|
||
|
|
files change. It creates a file containing a "date stamp"
|
||
|
|
which is used by the function "cygname" to create named
|
||
|
|
shared memory, events, mutexes, and semaphores used by
|
||
|
|
cygwin.dll. The unique datestamp allows multiple loading of
|
||
|
|
different cygwin.dll's even when they have incompatible use
|
||
|
|
of shared memory areas.
|
||
|
|
* init.cc (dll_entry): Create the name string used by cygname
|
||
|
|
from the name of the invoking .dll + the datestamp of the
|
||
|
|
.dll from the auto-generated datestamp.c
|
||
|
|
* misc.cc (cygname): New function. Creates a standard Cygnus
|
||
|
|
shared resource name given a prefix, a name (e.g., pinfo_mutex),
|
||
|
|
and a numeric suffix (e.g., a pid). Replaces custom code in
|
||
|
|
several files. Uses cygwin_dlldate from datestamp.c to construct
|
||
|
|
names that are unique for a given cygwin load.
|
||
|
|
* shared.cc (open_shared_file_map): Use standard cygname function
|
||
|
|
to create names for sharable objects. Use static handle 'h'
|
||
|
|
so that it can be closed later by shared_terminate.
|
||
|
|
(shared_terminate): Guard against calling CloseHandle with a
|
||
|
|
NULL handle.
|
||
|
|
(create_shared_fd_mapping_name): Use cygname function to generate
|
||
|
|
the name for the "fd_map".

|
|
for NTEA usage.
|
||
|
|
* ntea.cc: remove them from here
|
||
|
|

|
||
|
|
flag instead of GENERIC_WRITE
|

|
|
|

|
|
Thu Sep 11 15:35:10 1997 Ian Lance Taylor <ian@cygnus.com>

|
the element is the user's gid.

|
||
|
|
|
||
|
|
* Makefile.in: split subdir_do into subdir_dobefore and
|
||
|
|
subdir_doafter to reflect whether the subdir in question
|
||
|
|
should be built before or after the top level is built
|
||
|
|
(e.g. glob needs to be built before libcygwin.a but libcygwin.a
|
||
|
|
needs to be built before utils).
|
||
|
|
|
||
|
|
Thu Aug 28 12:09:39 1997 Geoffrey Noer <noer@cygnus.com>
|
||
|
|
|
||
|
|
* configure.in: when setting up EXE_LDFLAGS, correct the
|
||
|
|
location of crt0.o to ../../newlib since EXE_LDFLAGS is used

||
|
|

|
||
|
|

||
|
|
|
||
|
|

|

|
|
that were commented out, minor comment changes, remove
|
||
|
|
test.exe build rule.
|
||
|
|
|
||
|
|
Wed Aug 20 14:45:17 1997 Geoffrey Noer <noer@cygnus.com>
|
||
|
|
|
||
|
|
* Makefile.in: link cygwin.dll with -lm -lgcc -lc -lgcc instead
|
||
|
|
of -lc -lm -lm -lgcc so lgcc finds abort(). Add definitions that
|
||
|
|
will eventually be used to build a cygwindebug.dll used by gdb
|
||
|
|
so gdb can debug a buggy cygwin.dll. Change some variable names
|
||
|
|
to have underscores in them (DLL_NAME, LIB_NAME, DEF_FILE, etc.).
|
||
|
|
Comment out text.exe build rule.

|
||
|

librx since it is LGPL'd code.

|
||
|
|

|
prototypes.
|

Thu Jul 24 02:10:25 1997 Geoffrey Noer <noer@cygnus.com>
|
||
|
|
|
||
|
|
patch from sos@prospect.com.ru (Sergey Okhapkin):
|
||
|
|
* Makefile.in: Add tty.o to link and dependency lists, add
|
||
|
|
tty.h to headers list
|
||
|
|
* console.cc (fhandler_console::open): save open call flags
|
||
|
|
(fhandler_console::input_tcsetattr): clear all console modes if
|
||
|
|
tty support enabled
|
||
|
|
(FakeReadFile): restart read on signal delivering, changed CTRL
|
||
|
|
macro to CONTROL to avoid conflict with sys/termios.h, copy as
|
||
|
|
much as possible chars to output buffer instead of call to
|
||
|
|
undo_input after every char to prevent timeouts problem.
|
||
|
|
* cygwin.din: srandom, ptsname, grantpt, unlockpt - new exports.
|
||
|
|
* dcrt0.cc: include tty.h, new use_tty global variable.
|
||
|
|
(dll_crt0_1): call events_init() on application startup, set
|
||
|
|
use_tty to FALSE if CYGWIN_NOTTY environment variable is defined,
|
||
|
|
do not change console title if CYGWIN_NOTITLE environment
|
||
|
|
variable set, call tty_init().
|
||
|
|
(_exit): call tty_terminate(), events_terminate() and others
|
||
|
|
in the right order. All modifications of console title are
|
||
|
|
mutexed to allow tty code to obtain console window handle right.
|
||
|
|
* exceptions.cc (exception_init): initialization of signal_arrived
|
||
|
|
event moved to events_init().
|
||
|
|
(call_handler): raise signal arrived event after resuming main
|
||
|
|
thread.
|
||
|
|
(__cygwin_exception_handler): raise signal instead of calling
|
||
|
|
ctrl_c_handler, because exception handler is called in a context
|
||
|
|
of the thread, caused exception, and SuspendThread in call_handler
|
||
|
|
blocks itself :-)
|
||
|
|
(ctrl_c_handler): clear stopsig on SIGCONT delivery, call
|
||
|
|
ResumeThread until suspend count > 1, notify parent about child's
|
||
|
|
status changed. Care about handling SIGCONT signal. On stop
|
||
|
|
signals release vital mutexes used by stopped thread, save
|
||
|
|
signal number for wait(WUNTRACED) calls, notify parent about child's
|
||
|
|
status change. Do not stop processes running without job control
|
||
|
|
(when pgid == 0). Ensure that main thread is unblocked before
|
||
|
|
call _exit().
|
||
|
|
(events_init): new
|
||
|
|
(events_terminate): new
|
||
|
|
* fcntl.cc (_fcntl): use saved open flags on F_GETFL/F_SETFL instead
|
||
|
|
of game with access_ variable. Is this variable longer needed?
|
||
|
|
* fhandler.cc (fhandler_base::linearize/de_linearize): save/restore
|
||
|
|
openflags_ variable.
|
||
|
|
(fhandler_base::open): save file open flags.
|
||
|
|
* fhandler.h (fhandler_base): new openflags_ member, new member
|
||
|
|
functions get_flags/set_flags, new virtual functions ptsname,
|
||
|
|
dup_for_fork, tcget(set)pgrp
|
||
|
|
(fhandler_pipe): remove always_write/except_ready because pipes
|
||
|
|
are always write ready (not true...) and selectable on read.
|
||
|
|
new classes fhandler_tty_slave, fhandler_pty_master,
|
||
|
|
fhandler_tty_master
|
||
|
|
* fork.cc (cygwin_fork_helper1): inherit control tty number on fork,
|
||
|
|
call tty_init on child startup.
|
||
|
|
* hinfo.cc: include stdlib.h and ctype.h.
|
||
|
|
(hmap_init): take care on exec'ed processes.
|
||
|
|
(init_std_file_from_handle): open /dev/tty for standard handles if
|
||
|
|
tty usage enabled.
|
||
|
|
(build_fhandler): check for tty slave and pty master devices.
|
||
|
|
* include/exceptions.h: exception handler returns "int" (exception
|
||
|
|
handling code), not "void".
|
||
|
|
* include/termios.h: new defines, struct winsize must contain
|
||
|
|
ws_xpixel and ws_ypixel members (commented now to avoid
|
||
|
|
incompabilities with existing binaries. Should be uncommented in
|
||
|
|
next release.
|
||
|
|
* net.cc (gethostbyaddr): corrected return value
|
||
|
|
* passwd.cc (parse): remove trailing newline from password
|
||
|
|
lines (user's shell was reported with trailing newline before).
|
||
|
|
* pinfo.cc (lock_pinfo_for_update): open mutex code moved to
|
||
|
|
events_init() in exceptions.cc.
|
||
|
|
(destroy_pinfo_lock): removed, pinfo_mutex is now closed in
|
||
|
|
events_terminate() in exceptions.cc.
|
||
|
|
(init_self): the initial value for pgid must be 0 (no job-controlled
|
||
|
|
process).
|
||
|
|
* select.cc: all debug_printf's changed to select_printf.
|
||
|
|
(fd_pipe_map): new class to implement (polling...) select on pipes.
|
||
|
|
(pipethread): new
|
||
|
|
(cygwin32_select): comment out socket only case since generic
|
||
|
|
code (select on different types of handles) works for sockets too
|
||
|
|
but is interruptable. The case for always_ready_used is used now
|
||
|
|
and for polling select (zero timevalue). Changes to support
|
||
|
|
select on pipes.
|
||
|
|
* shared.cc (shared_info::initialize): initialize tty table.
|
||
|
|
* signal.cc (sleep/usleep/sigsuspend/pause): signal_arrived moved
|
||
|
|
from u area to dll's address space, signal_arrived is manual reset
|
||
|
|
event now.
|
||
|
|
(_raise): implemented as kill (self, sig).
|
||
|
|
(kill_worker): new. Use SendMessage instead of PostMessage to avoid
|
||
|
|
some timing problems.
|
||
|
|
* spawn.cc: include tty.h.
|
||
|
|
(spawn_guts) call close_all_files() on exec, call tty_terminate()
|
||
|
|
before process exit. Some changes due to moving signal_arrived to
|
||
|
|
dll's address space.
|
||
|
|
(_spawnve): inherit control tty number on spawn.
|
||
|
|
* syscalls.cc (close_all_files): reenabled. The code is ok after
|
||
|
|
all! The troubles were due to incorrect usage on exec() calls.
|
||
|
|
(setsid): no longer a stub
|
||
|
|
(ptsname): new
|
||
|
|
* termios.cc: all syscall_printf's changed to termios_printf.
|
||
|
|
(tcget(set)pgrp): rewritten, no longer a stub.
|
||
|
|
* times.cc (utimes): It looks like Win32 does not allow changing
|
||
|
|
times of directories, so just return success in this case.
|
||
|
|
* tty.cc: new file
