Raw Blame History

Thu Dec 31 16:50:32 1998 DJ Delorie <dj@cygnus.com>

signed vs. unsigned, char * vs. const char *, etc...
Wed Dec 30 21:41:25 1998 Christopher Faylor <cgf@cygnus.com>
* dcrt0.cc (do_exit): Remove previous dwProcessId
change as it presumes too much knowledge about signalling
in the wrong place in the code.
* sigproc.cc (sigproc_terminate): Move the dwProcessId
assignment here but only do it when it is necessary or
programs will die abnormally.
* fhandler.h: Add raw_write method to fhandler_serial.
* fhandler_serial.cc (raw_write): New method. Accomodates
overlapped I/O that now must be used with serial.
* utils/kill.cc (main): Allow `0' signal. Just checks
for existence of process.
Wed Dec 30 00:01:18 1998 Geoffrey Noer <noer@cygnus.com>
* include/cygwin/version.h: bump API_MINOR to 8 to mark
recently exported _ctype_, _sys_errlist, _sys_nerr. Briefly
describe all API_MINOR changes to date.
Wed Dec 30 01:31:34 1998 Christopher Faylor <cgf@cygnus.com>
* dcrt0.cc (do_exit): Set myself->dwProcessId so that
some exit routines will not falsely believe that this
process has been execed.
* select.cc (peek_serial): Remove debugging statements.
* sigproc.cc (sigproc_terminate): Detect state where
myself->dwProcessId == 0 as indicative of not being
an exec stub.
Tue Dec 29 21:13:33 1998 Christopher Faylor <cgf@cygnus.com>

select needs it. Add 'saw_error' field to select_record so
that select can detect error conditions.
* fhandler_serial.cc (fhandler_serial::raw_read): Detect
"operation aborted" error and retry. This seems to indicate
an attempt to retry an overlapped operation.
* select.cc (select_stuff::wait): Honor saw_error field when
appropriate.
(peek_serial): Rewrite to operate similarly to
fhandler_serial::raw_read.
* include/sys/termios.h: CBAUD mask was still not right.

Add dup and init methods to fhandler_serial.
* fhandler.cc (fhandler_base::init): Reorder arguments to mirror
open().
* fhandler_console.cc (fhandler_console::init): Ditto. Initialize
using fhandler_base rather than fhandler_serial as console is
now being slowly uncouple from fhandler_serial.

* signal.cc (sigprocmask): Ensure that signals are synchronized
by calling set_process_mask with sync == 1.
* sigproc.cc (__release_signal_mutex): Third argument is not
strictly a BOOL, so change it.
* sigproc.h: Reflect above parameter changes.
Thu Dec 3 15:30:44 1998 Christopher Faylor <cgf@cygnus.com>

Fri Nov 27 22:30:58 1998 Christopher Faylor <cgf@cygnus.com>
* fhandler.h: Set aside NOEINTR bit. When this is set
cygwin will not allow the read on this device to be
interrupted by a signal.
* pipe (_pipe): Set NOEINTR bit for read end of pipes
created using this method. The vague rationale for this
is that these pipes are supposed to be more like Windows
pipes than UNIX pipes.

* libcerr.c: Ditto.
Fri Nov 27 21:56:03 1998 Christopher Faylor <cgf@cygnus.com>
* exceptions.cc (SIG_NONMASKABLE): Update for new signal

Thu Nov 26 20:26:17 1998 Christopher Faylor <cgf@cygnus.com>
* exceptions.cc (call_handler): Attempt to work around

(handle_sigsuspend): Reset signal_arrived prior to
grabbing the mutex. This should reduce the probability
of a race.
* sigproc.cc (sig_send): Don't reset signal_arrived in
the SIGSUSPEND case since this could introduce a race.
Thu Nov 26 12:19:16 1998 Christopher Faylor <cgf@cygnus.com>
patch from sos@prospect.com.ru (Sergey Okhapkin):
* select.cc (MAKEready): Don't wait for signal prior to
testing for read. That introduces an unnecessary delay.
Wed Nov 25 23:03:47 1998 Christopher Faylor <cgf@cygnus.com>
* winsup.h: Make `isdirsep' an alias for SLASH_P.
Implement isabspath convenience macro.
Change sigprotect to a macro since it appears to
be impossible to send __FILE__ type macros to a
constructor. Change use of sig_protect throughout.
* dcrt0.cc (dll_crt0_1): Use new path macro.
* dlfcn.cc (get_full_path_of_dll): Ditto.
* path.cc (path_conv::path_conv): Ditto.
(normalize_posix_path): Ditto.

Use {get,release}_signal_mutex throughout.
(signal_init): Don't initialize signal_mutex here.
(set_process_mask): Remove vestiges of old mutex code.

(call_handler): Move signal_arrived SetEvent back here.
It was being triggered too often before.
Detect when the signal thread is exiting.

(events_terminate): Move close of signal_mutex elsewhere.
* glob.cc: Increase "MAXPATHLEN" size for arguments that
are not necessarily pathnames.
* pinfo.cc (lpfu): Lower timeout for reporting possible
problem with INFINITE wait.
* sigproc.cc (wake_wait_subproc): Make this a macro with
no arguments so that its use in the code is a little
clearer.
(proc_terminate): Eliminate signal blocking here since
this should already be handled by the caller.
(sigproc_init): It makes sense to initialize signal_mutex
here, so do so.
(__allow_sig_dispatch): Rename. Take debugging arguments.
Pass arguments on to release_signal_mutex.
(__block_sig_dispatch): Rename. Take debugging arguments.
Pass arguments on to get_signal_mutex. Detect signal
thread exiting confition.
(__get_signal_mutex): Take debugging arguments. Maintain
a stack of nested mutex calls for later display in
__release_signal_mutex. Detect signal thread exit
condition. Don't bother with locking if signal thread is
executing or if just an exec stub.
(__release_signal_mutex): Don't bother with locking if signal
thread is executing or if just an exec stub.
* sigproc.h: Reflect renamed functions above. Provide
wrappers to pass in diagnostic information.
* spawn.cc (spawn_guts): More fixes to deal with nested
#! and to properly report posix argv[0] when invoked as a
script.
Wed Nov 25 12:41:12 1998 Christopher Faylor <cgf@cygnus.com>

and CXXFLAGS in FLAGS_TO_PASS.
* include/sys/select.h: new file with select proto. Avoid
potential conflict with Winsock inclusion by Cygwin internals.
* include/sys/socket.h: remove select proto.
* winsup.h: define __INSIDE_CYGWIN__. Include windows.h after
Unix include files.
* include/mywinsock.h: delete file
* include/Windows32/Sockets.h: add ndef __INSIDE_CYGWIN__s
around portions that conflict with Unix definitions. This
yields what used to be mywinsock.h which is a blend of Unix
sockets and Winsock needed by Cygwin internals.
* exceptions.cc: define Win32_Winsock to include
Windows32/Sockets.h. No longer define __INSIDE_CYGWIN__.
* hinfo.cc: ditto
* net.cc: ditto

in an argument.
(insert_file): Don't scan command line. Accept already
parsed arguments from build_argv.
(quoted): New function for parsing quoted strings.
(globify): Don't scan argv list. Accept element from

* debug.cc (class locker): Fix previous change. Critical
sections are still required, so protect them if operating

NO_COPY. Rename these variables to something that is not
likely to be collided with.

signal here and wait a long time for the mutex before giving
up. Should increase performance slightly.
* sigproc.cc (maintid): New external symbol.
* sigproc.cc (maintid): Make this global since it is used
in other places now.
(sig_dispatch_pending): Don't wait for wait_sig to complete
if there are no pending signals. Avoids a race and should
be faster.

since it is not signal safe.
* syscalls.cc (_read): Remove duplicate CreateEvent typo.

thread handle since it is protected.
Thu Sep 24 18:59:25 1998 Geoffrey Noer <noer@cygnus.com>
* path.cc (mount): don't verify that path is an existing
directory. Instead
* utils/mount.cc: verify that path is an existing directory
and print warning if it's not. Still do the mount.
Thu Sep 24 11:45:04 1998 Christopher Faylor <cgf@cygnus.com>
* debug.cc: locker class variables must be NO_COPY since
they contain data that should not be precisely duplicated
after a fork. This hopefully fixes a "SIGSEGV" problem.

signal mask calculation based on whether binary was linked with
"older" or "newer" cygwin.

output.
* termios.cc (tcflow): Signal protection.
(tcgetattr): Ditto.
(tcsetattr): Make signal protection synchronous.

PROG and return extension found or NULL if no matching file.

(dll_crt0_1): calls insert_files before building argv
Wed Mar 25 15:25:26 1998 Geoffrey Noer <noer@cygnus.com>
And more:
* {fhandler.cc, fhandler.h, tty.cc, net.cc, console.cc}: make
ioctl calls' cmd arg unsigned, ditto for access arg of init calls.
* console.cc (fhandler_console::fillin_info): add parens around
assignment used as truth value.
(FakeReadFile): make copied_chars a size_t
(fhandler_console::read): make i in loop unsigned
* environ.cc (setenv): make l_value unsigned, add parens around
assignments used as truth values.
* exceptions.cc (call_handler): supposed to return an int and
wasn't at the end of control flow. Now returns 1 there.
* fhandler.h (~fhandler_base): destructor should be marked virtual
* misc.cc (login): add parens around assignment used as truth
value.
* net.cc: cast INVALID_SOCKET to int in comparisons
(fhandler_socket::ioctl): remove int cast to FIONBIO since cmd
is now unsigned
(get_win95_ifconf): add cast to signed vs unsigned int comparison.
* ntea.cc (NTReadEA): add cast to signed vs unsigned int
comparison.
* path.cc (getcwd_inner): make len a size_t
* pinfo.cc (cygwin32_winpid_to_pid): add comment
* select.cc (cygwin32_select): make wait_ret an int
* signal.cc (kill_worker): add parens around assignments used as
truth values.
* sigproc.cc (wait_sig): make rc a DWORD
(sig_send): add parens around assignment used as truth value.
* strace.cc: make inqueue global a static DWORD
* tty.cc (do_output): add cast to signed vs unsigned int
comparison.
(fhandler_pty_master::open): remove unused handle nh
Tue Mar 24 18:03:59 1998 Geoffrey Noer <noer@cygnus.com>
More spring cleaning:
* net.cc: move LOAD macro definition out of winsock_init,
correction to make it valid ANSI C++.
* grp.cc (read_etc_group): pass default line directly to
add_grp_line call
Mon Mar 23 19:21:00 1998 Geoffrey Noer <noer@cygnus.com>
patch from cgf@bbc.com (Christopher Faylor):
* spawn.cc (spawn_guts): Don't call close_all_files if a cygwin
process has been spawned. Otherwise, we close tty handles twice.
Fri Mar 20 23:01:24 1998 Geoffrey Noer <noer@cygnus.com>
* pinfo.cc (pinfo_list::init): Initialize next_pid to PBASE.
(pinfo_list::operator []): Now index is given by pid mod size().
(pinfo_list::allocate_pid): Allow more pid numbers than spaces in
the process table. Pids now can range from PBASE (1000) to
INT_MAX. At that point they wrap to 1000 again. For speed, use
modular arithmetic to map pids into table.
* winsup.h: move PBASE to pinfo.cc, rename next_pid_index to
next_pid
* utils/ps.cc (main): reorg of what's printed where, listing pid
first.
Thu Mar 19 15:05:07 1998 Geoffrey Noer <noer@cygnus.com>
* winsup.h: Change section name in NO_COPY definition. We were
using a .data$nocopy section to avoid copying certain data on
fork. The linker used to include this between __data_start__ and
__data_end__, but that broke building the cygwin32 dll. The fix
is to rename the section ".data_cygwin_nocopy" and explictly
include it after __data_end__.
Wed Mar 18 15:03:51 1998 Geoffrey Noer <noer@cygnus.com>
* tty.h: fix ttyslot proto; it returns an int
* glob.h: fix glob proto; it returns an int

Mon Mar 16 11:56:23 1998 Geoffrey Noer <noer@cygnus.com>
patch from cgf@bbc.com (Christopher Faylor):
* tty.cc (fhandler_tty_slave::dup): Don't set flags to 0. Flags
have already been set in wrapper.

* termios.cc: ditto
* time.cc: ditto
Tue Mar 10 15:54:04 1998 Geoffrey Noer <noer@cygnus.com>
* version.h: up CYGWIN_DLL_VERSION_MINOR
Tue Mar 10 15:41:29 1998 Geoffrey Noer <noer@cygnus.com>
patch from cgf@bbc.com (Christopher Faylor):
* spawn.cc (spawn_guts): Make argument handling after `#! pgm'
handle spaces similarly to UNIX. Close "linearized" file handles
when a non-cygwin32 binary is executed or suffer hangs on exit.
Reorganize lpReserved2 buffer to avoid conflicts with Microsoft
usage which resulted in incorrect stdin/stdout operation with
programs compiled using MSVC.
* pinfo.cc (pinfo_init): Accomodate change to lpReserved2
organization.
Mon Mar 9 19:27:17 1998 Geoffrey Noer <noer@cygnus.com>
* syscalls.cc (_open): modify to take a variable number of
arguments to match newlib's fcntl.h.
* environ.cc (parse_options): rewrite struct known to conform
to ANSI standards. Can't statically initialize, so do so
dynamically at the beginning of the function instead.
patch from jeffdb@netzone.com (Mikey):
* dcrt0.cc (build_argv, compute_argc): need to escape quotes
Sat Feb 28 16:41:54 1998 Geoffrey Noer <noer@cygnus.com>

ScreenGetCursor, ScreenSetCursor.
Sun Feb 22 17:44:55 1998 Geoffrey Noer <noer@cygnus.com>

compiles with egcs. Will rewrite/enable later.
Sun Feb 22 13:49:10 1998 Geoffrey Noer <noer@cygnus.com>

(fhandler_tty_slave::open): Set slave_opened.
(fhandler_pty_master::open): Initialize slave_opened.
* tty.cc (fhandler_pty_master::read): Change type of n to DWORD.
If there are no characters to read, and the descriptor is in
nonblocking mode, just return EGAIN.
Mon Feb 16 15:11:25 1998 Ian Lance Taylor <ian@cygnus.com>
* tty.h (class tty): Remove handle_pid and slave_handles fields.
(class tty_list): Add getcount method.

(tty_list::free_tty): If we just freed the last reference to this
tty, close input_handle and output_handle.
(fhandler_tty_master::init): Don't initialize handle_pid and
slave_handles.
(do_output): Instead of just calling ReadFile, loop using
PeekNamedPipe and check whether the tty has been closed. Return 0
on EOF and -1 on error.
(process_output): Only print debugging error message if error
occurs in do_output.
(fhandler_tty_slave::open): Always duplicate handles from master.
Never close handles in source. Don't change slave_handles.

patch from cgf@bbc.com (Christopher Faylor):
* utils/cygwin.cc: Modify -s option to use new strace_mask entry
in pinfo. Prepare for future ability to specify an strace file.
Thu Feb 12 11:57:26 1998 Geoffrey Noer <noer@cygnus.com>
* grp.cc (read_etc_group): add a default /etc/group in memory
if /etc/group isn't found

of returning a default group
Wed Feb 11 15:59:10 1998 Geoffrey Noer <noer@cygnus.com>
patch from sos@prospect.com.ru (Sergey Okhapkin):
* strace.cc (strace_open): do not close u->strace_file if it
points to stderr.
* malloc.cc (malloc_init): do not check for application's malloc
in a forkee, this breaks memory coherency in a forkee and forker.
use_internal_malloc flag now copies on fork.
Tue Feb 10 18:11:30 1998 Geoffrey Noer <noer@cygnus.com>
patch from cgf@bbc.com (Christopher Faylor)
Throughout sources, mark statics and globals as NO_COPY where
appropriate.
* fork.cc (cygwin_fork_helper1): Remove #if 0 around fork_copy of
cygwin data/bss. Remove __malloc_copy since it is no longer
necessary.
Tue Feb 10 15:30:19 1998 Geoffrey Noer <noer@cygnus.com>
patch from cgf@bbc.com (Christopher Faylor)
* console.cc (fhandler_console::write): Implement xterm style

avoiding running the destructor.
Mon Feb 9 13:53:50 1998 Geoffrey Noer <noer@cygnus.com>
patch from cgf@bbc.com (Christopher Faylor):
Moves all environment manipulation into environ.cc.
Switches to CYGWIN32 for settings:
set CYGWIN32=[no]title [no]strip_title [no]binmode [no]glob
strace=mask:cache,file [no]tty
(set STRACE=whatever is still honored).
Propagates tty settings to all subprocesses regardless of
unsetting of environment variable.
Moves strace mask into pinfo structure for easier future
manipulation by external program. Moves strace_file into the
vacated position for automatic use in forked processes.
Propagates old title to execed processes so that they can
correctly restore the correct title when they exit.
* console.cc: Use PID_USETTY setting in process_state so that
tty state can be easily inherited.
(set_console_title): New function to set console title.
* syscalls.cc: Use PID_USETTY setting in process_state so that
tty state can be easily inherited.
* tty.cc: Ditto.
* hinfo.cc: Ditto.
(hinfo_vec::de_linearize_fd_array): Return last location in buffer
for further potential processing.
* dcrt0.cc: Add global variables for control of glob and title,
set by environ_init. Mark some variables as NO_COPY.
Remove routines and variables for dealing with environment.
(dll_crt0_1): Move environment initialization into separate
function. Honor 'noglob' CYGWIN32 setting.
* environ.cc (environ_init): New function to initialize the
environ table. Also scans for CYGWIN32 environment variable,
setting appropriate values.
(ucenv): New function. Upper cases an environment variable.
(parse_options): New function. Parse CYGWIN_* environment
variable.
(posify): New function. Convert a Windows env path spec to
cygwin.
(env_sort): New function. Sort an environ block.
(winenv): New function. Returns a windows style environment
block.
* fhandler.cc (fhandler_base::read): Reflect change to location of
strace_mask.
* fork.cc (cygwin_fork_helper1): Remove save/restore of some
settings since this is automatic now with new dll data copy. Save
PID_USETTY setting in child process_state.
* strace.h: Cosmetic change.
* pinfo.cc (pinfo_init): Call environ_init here since it may
affect further processing in this function. Use old console title
from "parent" process if execed process. Reflect change to
location of strace_mask.
* spawn.cc (spawn_guts): Remove environment manipulation code.
Use new winenv function call instead. Save old title in block of
memory copied to newly execed process if title is being displayed.
* strace.cc: Changes to reflect new location for strace_mask and
strace_file. These are now automatically inherited on fork.
* winsup.h: Move strace_mask into pinfo to allow possible
manipulation by other processes. Put u->strace_file in uptr
structure so that it will be automatically duplicated on fork,
removing the necessity of initializing strace in a forked
process. Add functions/variables associated with environment
manipulation and console title setting.
Mon Feb 9 03:06:56 1998 Geoffrey Noer <noer@cygnus.com>
Extensive reformatting in new files from next patch.
Rename dllinit.h file to dll_init.h and likewise for dll_init.cc.
Rename cygwin_detach_dll to cygwin32_detach_dll throughout.
Similarly, rename cygwin_attach_dll and _cygwin_dll_entry.
And rename sanityAndSyncCheck to check_sanity_and_sync.
Also:
* dll_init.h: don't include winsup.h
* dll_init.cc: include winsup.h here instead
* dlfcn.cc: include winsup.h, don't include windows.h
* cygwin.din: rename cygwin_detach_dll to cygwin32_detach_dll.
patch from giac@dalim.de (Philippe Giacinti):
Copy data areas of cygwin-compiled dlls on fork(),
implement dlopen/dlsym/dlclose/dlerror calls.
* Makefile.in: add dlfcn.o and dllinit.o to DLL_OFILES, add
dllinit.h dependencies
* cygwin.din: dll_dllcrt0, cygwin_detach_dll, dlopen, dlclose,
dlsym, dlerror, dlfork -- new exports.
* dcrt0.cc: include dllinit.h, mark u pointer as NO_COPY.
(sanityAndSyncCheck): new, code moved from dll_crt0_1.
Initialize all linked dlls before calling main().
* dlfcn.cc: new file.
* dllinit.cc: new file.
* dllinit.h: new file.
* exceptions.cc: mark some variables with NO_COPY.
* fork.cc: include dllinit.h; declare cygwin.dll data/bss
start/end.
(cygwin_fork_helper1): copy data/bss of cygwin.dll itself to child
process (the code is disabled now); copy data areas of
linked/loaded dlls (if any); free loaded dll list on cleanup.
* include/cygwin32/cygwin_dll.h: new file.
* include/dlfcn.h: new file.
* libccrt0.cc (cygwin_crt0_common): new, code derived from

* strace.cc: mark some data as NO_COPY
* winsup.h: add dll_dllcrt0 proto, NO_COPY macro.
Sun Feb 8 17:51:26 1998 Geoffrey Noer <noer@cygnus.com>
* getopt.c: new. Import Berkeley getopt code modified for use
in Cygnus' kerberos implementation (including the writing of
getopt_long by Chris Provenzano (proven@cygnus.com)) then modified
a bit more to get it working in Cygwin32. Although we were
going to remove getopt, it appears that too many programs would
need fixing to remove it completely. Whether getopt should be
included in Cygwin32 should be decided at a later time.
* include/getopt.h: new. Import Berkeley getopt.h.
* Makefile.in: add getopt.o to LIBCOS
* utils/Makefile.in: remove include of ../../include since
getopt.h is now in winsup/include, also revert recent change
of addition of GETOPT_OBJS.
Fri Feb 6 16:28:19 1998 Geoffrey Noer <noer@cygnus.com>

which is linked in for cygwin.exe
Thu Feb 5 17:59:12 1998 Geoffrey Noer <noer@cygnus.com>
syscalls.cc: move ppc dll_entry asm code to...
dcrt0.cc: ...here
Import new globbing code from NetBSD 1.3

from DLL_IMPORTS, fix dcrt0 glob.h dependency
* configure.in: don't configure glob subdirectory
* configure: regenerate
* dcrt0.cc: include glob.h, not glob/glob.h.
(globify): don't call glob with GLOB_NOESCAPE which isn't a valid
flag with this glob
Wed Feb 4 16:14:13 1998 Geoffrey Noer <noer@cygnus.com>
patch from sos@prospect.com.ru (Sergey Okhapkin):
Allow system administrator to enter into the HKLM registry tree
a predefined mount table inherittable by all cygwin users. The
predefined mounts are non-mandatory so the user's mount table has
a higher priority than the default one. Cygwin reads HKLM tree
in read-only mode.
* path.cc (read_mounts): new, code derived from
mount_info::from_registry().
(mount_info::from_registry): call read_mounts from user's table,
then from system-wide mount table.
* registry.cc (reg_session::reg_session): key and access arguments
added.
(reg_key::init): access argument added.
(reg_key::reg_key): access argument added.
* registry.h (class reg_key): init prototype changed, default
argument of reg_key added.
(class reg_session): default arguments of constructor added.
Wed Feb 4 15:38:59 1998 Geoffrey Noer <noer@cygnus.com>
* include/a.out.h: new coff header file
Wed Feb 4 01:55:18 1998 Geoffrey Noer <noer@cygnus.com>
* uinfo.cc: define DEFAULT_UID/GID here
* winsup.h: removed DEFAULT_UID/GID defs and unused
set_console_title proto. Did some major reorganizing,
and a little reformatting, commenting.
Tue Feb 3 23:59:23 1998 Geoffrey Noer <noer@cygnus.com>
patch from cgf@bbc.com (Chris Faylor):
Replace u->self and this_procinfo () with new `myself' pointer
wherever appropriate. Also replace get_pid() calls with a
simple ->pid reference.
Mon Feb 2 12:34:49 1998 Geoffrey Noer <noer@cygnus.com>
patch from sos@prospect.com.ru (Sergey Okhapkin):
* console.cc (FakeReadFile): limit bytes to read to 30000 due to
Win NT 4.0 SP3 bug. Kill foreground process group with SIGWINCH
on console buffer size change if tty support enabled.
* include/sys/termios.h: define more constants.
* tty.cc (fhandler_pty_master::ioctl): kill foreground process
group with SIGWINCH on window resizing.
Mon Feb 2 12:14:49 1998 Geoffrey Noer <noer@cygnus.com>
patch from cgf@bbc.com (Chris Faylor):
* dcrt0.cc (dll_crt0_1): Initialize u->self here, early in a
forked process so the correct pid is used in strace output and so
signals do not end up being erroneously sent to the parent.
* exceptions.cc: Make a global variable static. Some minor
optimizations.
(call_handler): Make sure that the signal mask is restored when
sig_dispatch mutex is unavailable.
Reorder asm statements to prevent clobbering of flags register by
preceding ors or risk random inexplicable behavior when returning
from a signal handler.
* fork.cc (cygwin_fork_helper1): Put setjmp restore in child's
pinfo. Have the child figure out its pid earlier in the
initialization process. Don't print a "child failed" error if the
child failed during initialization due to a CTRL-C. This is still
not quite right (see comment).
* sigproc.cc (sig_send): Remove unlock/lock_pinfo or suffer
consistent hangs in zsh. Make {allow,block}_sig_dispatch globally
available.
(wait_sig): Fix problem where blocked signals would still be
processed if queued. Add debugging SIGNOQUEUE conditional to turn
off signal queueing, making cygwin more like traditional UNIX.
* sigproc.h: Add {allow,block}_sig_dispatch functions.
Mon Jan 26 17:33:57 1998 Geoffrey Noer <noer@cygnus.com>
* path.cc (mount_info::init): don't hardcode C: as the default
slash mount. Instead, use the drive letter that the OS is loaded
on.
Mon Jan 26 13:33:57 1998 Geoffrey Noer <noer@cygnus.com>
patch from cgf@bbc.com (Chris Faylor):
* fork.cc (cygwin_fork_helper): Move setting PID_INITIALIZING
process_state here to avoid erroneously setting it permanently
via proc_register().
* pinfo.cc (pinfo_init): Delay notifying "parent" when execing
until this process is ready to receive signals or risk a race
condition if exec parent calls sigproc_terminate prior to
the child exec.
* sigproc.cc (proc_subproc): Don't set PID_INITIALIZING here.
It is too late in the process creation.
(sig_send): Reset sigsuspend mutex prior to use to avoid a race.
(wait_sig): Create sigsuspend mutex as an auto reset to attempt
to avoid a race condition. Notify parent that this process is
ready if we were execed (code moved from pinfo_init). Change
PulseEvents to SetEvents to avoid races
* spawn.cc (spawn_guts): Move setting PID_INITIALIZING
process_state here to help avoid race.
Fri Jan 23 12:31:37 1998 Ian Lance Taylor <ian@cygnus.com>

Thu Jan 22 18:46:40 1998 Ian Lance Taylor <ian@cygnus.com>
* tty.h (class tty): Change slave_handles to int.
* tty.cc (fhandler_tty_slave::open): Check for invalid tty
handles. If this is the first slave, set slave_handles to 2;
otherwise, increment slave_handles.
(fhandler_tty_slave::close): Only close the tty handles if the
slave_handles field drops to 1.
(fhandler_tty_slave::write): Add a debugging message if WriteFile
fails.
(fhandler_tty_slave::dup): Set ttynum of new fhandler. Increment
slave_handles if appropriate.
(fhandler_pty_master::close): Only close the tty handles if the
tty is no longer allocated.

* tty.cc (attach_tty): Call connect_tty even if use_tty is not
set.
(detach_tty): Don't check use_tty.
(fhandler_tty_master::init): Initialize handle_pid and
slave_handles of tty.
(do_input): Treat \r as end of line character.
(do_output): Only set output_done_event if it is not NULL.
(fhandler_tty_slave::open): Don't worry if we can't open
output_done_event. Check slave_handles field of tty to decide
from where to duplicate the handles. Call detach_tty on error.
If we are now the owner of the slave handles, mark the tty
appropriately.
(fhandler_tty_slave::close): Only close output_done_event if it is
not NULL. Check for errors from CloseHandle. Close the tty
handles if we own them.
(fhandler_tty_slave::write): Only wait for output_done_event if it
is not NULL.
(fhandler_tty_slave::read): If nobody owns the tty, return EOF.
(fhandler_tty_slave::dup): Attach the tty. Don't duplicate
output_done_event if it is NULL. Detach the tty on error.
(fhandler_pty_master::open): Initialize handle_pid and
slave_handles of tty. Don't create output_done_event.
(fhandler_pty_master::close): Only close output_done_event if it
is not NULL. Check for errors from CloseHandle. Only close the
tty handles if we own them.
(fhandler_pty_master::read): Only set output_done_event if it is
not NULL.
* hinfo.cc (de_linearize_fd_array): Don't set use_tty just because
we find a tty to delinearize.

(mount_info::to_registry): ditto
(mount_item::getmntent): when setting ret.mnt_opts, only consider
text vs binary flag
(mount_item::init): remove init of mixed
* path.h: remove mixed_p, mixed from path_conv class. Remove
unmixedcaseify proto.
* include/sys/mount.h: comment out MOUNT_MIXED define, protect
header against multiple inclusion
A little header file cleanup. Mostly to protect headers against
multiple inclusion. Some aren't strictly speaking necessary but...
* include/sys/cygwin.h: protect header against multiple inclusion
* include/sys/smallprint.h: ditto, also add cplusplus wrapper
* include/sys/strace.h: comment last endif
* include/cygwin32/in.h: change _LINUX_IN_H protect defines
to _CYGWIN32_IN_H

(strace_init): Set strace_stderr.
(system_printf): If not strace_stderr, use debug_printf to put the
message in a trace file.
* fhandler.h (fhandler_pty_master): Add neednl_ field.
* tty.h (RESTART_OUTPUT_EVENT): Change to be different from
IOCTL_DONE_EVENT.
* tty.cc (fhandler_tty_master::init): Initialize neednl_.
(do_output): Handle a length of one by using neednl_ to record an
expansion of \n to \r\n which doesn't fit. Never expand \r to
\r\n. Correct order of \r\n.
(fhandler_tty_slave::open): Improve error handling. Use
DUPLICATE_CLOSE_SOURCE to close the pipes in the master process.
(fhandler_tty_slave::dup): Duplicate the handles, rather than
calling fhandler_tty_slave::open.
(fhandler_pty_master::open): Initialize neednl_.
(fhandler_pty_master::read): Return EOF for ERROR_BROKEN_PIPE,
rather than error. Set errno correctly.
* hinfo.cc (digits): New static function.
(build_fhandler): Always accept /dev/ptmx and /dev/ttyDDD, even if
use_tty is not set. use_tty now only controls the interpretation
of /dev/tty.
Mon Jan 19 14:49:45 1998 Geoffrey Noer <noer@cygnus.com>
* sigproc.cc (sig_send): lock_pinfo_for_update during this
function
Fri Jan 16 18:09:59 1998 Geoffrey Noer <noer@cygnus.com>
* sigproc.cc (sigproc_init): if we can't create a signal
thread or can't create sync_proc_subproc mutex, fail with
an api_fatal call rather than just returning
Fri Jan 16 18:08:49 1998 Geoffrey Noer <noer@cygnus.com>
patch from cgf@bbc.com (Chris Faylor):
Changed signal handling to use one semaphore and one shared
memory array which is manipulated via Interlocked*() functions.
* exceptions.cc (lock_cs): Comment. Report on error.
(unlock_cs): Add debugging statement.
(sig_dispatch_pending): Remove obsolete function.
(set_process_mask): Adapt to new signal method.
(call_handler): Clear wait()ing threads here while main thread is
suspended to avoid timing screwups. Avoid calling the handler if
can't get dispatch mutex (code moved from sig_handle). Return
status of acquiring the sig_dispatch mutex.
(sighandle): Adapt to new signal method. Reorganize to *always*
honor sig_dispatch mutex or suffer deadlock on fatal signals when
someone else has the mutex and we're attempting to cleanup.
(events_init): Reflect change in cygname() arguments.
* fork.cc (stack_dummy): New function. Returns address of
argument to determine bounds for eventual stack copy.
(cygwin_fork_helper1): Call subproc_init to start up subproc
thread if it is not alreay started. Ensure that signals are
blocked while forked process is initializing. Change method of
calculation for lower stack bounds to slightly more foolproof
method. Preserve some global settings in forked process.
* misc.cc (cygname): Remove an unused argument.
* pinfo.cc (pinfo_list::allocate_pid): Add a useful debugging
statement.
* shared.cc (open_shared_file_map): Reflect change in cygname()

(sigpending): Adapt to new signal method.
* sigproc.cc: Many changes to adapt to new signal method. Also
delay waits for thread initialization until the thread needs to be
contacted.
* sigproc.h: Ditto.
* spawn.cc (spawn_guts): Fix potential off-by-one error(?) in
transcribing the argument list and add paranoid code to detect
future overruns. Change priority to highest so that waiting
process will clear out quickly.
(_spawnve): Call subproc_init() to start up subproc thread if is
not already started.
* strace.cc (strace_printf): Increase size of internal buffer so
that long argument lists printed from spawn_guts do not overrun it
so easily.
* wait.cc (wait4): Set status flag to -1 prior to exit. This will
cause previous wait that was interrupted by a signal which
dispatched to another wait to return the correct error value.
* winsup.h (pinfo): Add _sigtodo array for new signal method.
Remove obsolete field. Reflect change in cygname arguments.
Thu Jan 15 13:07:07 1998 Ian Lance Taylor <ian@cygnus.com>

(_unlink): Don't permit the file to be removed if the directory is
not writable.
(rename): Don't permit the rename if either the source or
destination directory is not writable.
* syscalls.cc (chown): Set username and groupname lengths to UNLEN
+ 1, rather than 100. If getpwuid fails, try to look up the real
user name to see if it is the same. Don't report an error if
there is no security mapping.
Wed Jan 14 15:34:20 1998 Ian Lance Taylor <ian@cygnus.com>
* syscalls.cc (setegid): New function which just returns ENOSYS.

* syscalls.cc (setmode): Rename from _setmode. Change to return
the old mode. Remove old setmode function.
* cygwin.din: Make _setmode an alias for setmode.
Wed Jan 14 14:46:00 1998 Geoffrey Noer <noer@cygnus.com>
* Makefile.in: don't strip cygwin.dll by default

Mon Jan 12 13:53:03 1998 Geoffrey Noer <noer@cygnus.com>
patch from cgf@bbc.com (Chris Faylor):
Speed up cygwin pid calculation by staying in the range
1000 through (1000 + PSIZE - 1).
* pinfo.cc (pinfo_list::init): Change to reflect new pid
calculation method.
(pinfo_list::operator []): Ditto.
(pinfo_list::allocate_pid): Ditto.
* winsup.h (pinfo): Move pid and ppid into non-zeroed region since
they are always set by allocate_pid.
(pinfo_list): Change pid_base to next_pid_index to reflect new pid
calculation method.
(PBASE): New constant for new pid calcuation method.
Sat Jan 10 12:06:38 1998 Geoffrey Noer <noer@cygnus.com>
* syscalls.cc (process_deletion_queue): remove wrapper function

s->delqueue.process_queue instead of using above wrapper.
* winsup.h: remove process_deletion_queue proto
* delqueue.h: up MAX_DELQUEUES_PENDING to 100 for now. Rename
v to dqueue for clarity.
* delqueue.cc: v renamed to dqueue throughout. Add FIXME
describing why this whole delqueue system needs rewriting.
Fri Jan 9 13:18:44 1998 Geoffrey Noer <noer@cygnus.com>
Remove some historical baggage:
* syscalls.cc (cygwin_set_attributes): remove commented-out code,
add FIXME since this function should go away next time an
incompatible change to cygwin.din is made. Stop including
include/sys/cygwin.h.
* include/sys/cygwin.h: remove cygwin_set_attributes proto.
Remove CYGWIN_FMODE_ALL_BINARY define.
* hinfo (hinfo_vec::init_std_file_from_handle): remove old
commented-out code

Conform to POSIX method for sending SIGHUP to stopped processes.
* dcrt0.cc (do_exit): Use new kill_pgrp function to kill orphaned
children on group leader exit iff the children are stopped (per
POSIX).

patch from cgf@bbc.com (Chris Faylor):
* fhandler.cc (fhandler_base::open): include
FILE_FLAG_BACKUP_SEMANTICS in file_attributes when file is
a directory. Allows opening of directory as a file. Allows
use of handle to perform some operations on both directories and
files.
(fhandler_base::fstat): Loop when attempting to get volume serial
number. Works around an apparent Windows NT 3.51 bug.
* times.cc (utimes): use FILE_FLAG_BACKUP_SEMANTICS flag
to allow accessing directory times (may only work under NT;
until now it didn't work under either OS).
* winsup.h: Add O_DIROPEN constant.
Mon Jan 5 19:18:01 1998 Geoffrey Noer <noer@cygnus.com>
* Makefile.in: make winsup.h depend on winsup.h in accordance
with below
patch from cgf@bbc.com (Chris Faylor):

for kill_pgrp.
Mon Jan 5 18:30:37 1998 Geoffrey Noer <noer@cygnus.com>
Fix spoofing of directory inodes.
* syscalls.cc (hash_path_name): instead of initializing the
hash to zero, take the value of the initial hash as a new
argument.
(_stat_worker): fix up hash_path_name reference in light of above
* dirsearch.cc (opendir): initialize dir->__d_dirhash to the
hash of the full directory name so readdir can make use of it.
(readdir): compute d_ino by combining the directory hash
calculated by opendir with the hash of the filename.
* fhandler.cc: fix up hash_path_name reference in light of above
* winsup.h: remove unnecessary protos for getkey, kbhit. Adjust
hash_path_name proto.
