devbufalign.
(class fhandler_dev_floppy): Remove member bytes_per_sector;
* fhandler_floppy.cc (bytes_per_sector): Define as devbufalign.
(fhandler_dev_floppy::open): Set devbufalign to a multiple of the
sector size and handle devbuf allocation and alignment in !O_DIRECT
case here. Change comment accordingly.
Call FSCTL_ALLOW_EXTENDED_DASD_IO for partitions as well.
(fhandler_dev_floppy::raw_write): Fix comment. Rewrite and fix
writing behaviour when application uses read and lseek.
(fhandler_dev_floppy::lseek): Use rounddown macro. Call
SetFilePointerEx rather than the old SetFilePointer.
(fhandler_dev_floppy::ioctl): Reformat switch. Call
IOCTL_DISK_UPDATE_PROPERTIES rather than IOCTL_DISK_UPDATE_DRIVE_SIZE
in BLKRRPART case. Support BLKIOMIN, BLKIOOPT, BLKPBSZGET and
BLKALIGNOFF.
* fhandler_raw.cc (fhandler_dev_raw::fhandler_dev_raw): Initialize
all devbuf-related members.
(fhandler_dev_raw::~fhandler_dev_raw): Delete devbufalloc rather than
devbuf.
(fhandler_dev_raw::open): Drop allocating devbuf.
(fhandler_dev_raw::dup): Allocate devbufalloc and set devbuf to support
new sector-aligned devbuf handling.
(fhandler_dev_raw::fixup_after_exec): Ditto.
* fhandler_tape.cc (fhandler_dev_tape::open): Ditto, set devbufalign
to 1.
* include/cygwin/fs.h (BLKIOMIN): Define.
(BLKIOOPT): Define.
(BLKALIGNOFF): Define.
(BLKPBSZGET): Define.
output_mutex on CTRL-S/CTRL-Q to avoid a deadlock.
* fhandler_tty.cc (fhandler_pty_slave::write): Loop when output_stopped is
detected before acquiring output_mutex. Acquire output_mutex in the loop for
each write.
* tty.h: Remove some obsolete defines.
(tty_min::output_stopped): Make 'bool'.
* cygtls.h (_cygtls::push): Inline.
(_cygtls::interrupt_now): Change signal number argument to siginfo_t argument.
(_cygtls::interrupt_setup): Ditto.
(_cygtls::set_siginfo): Delete declaration.
(_cygtls::reset_signal_arrived): Don't reset signal_arrived signal. Just reset
flag.
* exceptions.cc (_cygtls::interrupt_now): Reflect argument changes. Pass si to
interrupt_setup.
(_cygtls::interrupt_setup): Reflect argument changes. Fill out tls infodata
here using passed-in si. Use si.si_signo instead of sig.
(sigpacket::setup_handler): Move this function into sigpacket class. Use si
field from the class as appropriate.
(sigpacket::process): Don't call tls->set_siginfo here since setup_handler
could fail. Eliminate now-unneeded sig argument.
* sigproc.h (sigpacket::setup_handler): Move setup_handler to this class.
read-ahead buffer for reading Windows clipboard if caller's
buffer is too small for complete characters.
* include/limits.h: Remove outdated TODO comment.
* cygtls.cc (_cygtls::operator HANDLE): Return NULL when tid is not set.
* exceptions.cc (setup_handler): Don't try to suspend a thread if it has no
handle.
(_cygtls::set_signal_arrived): Lock creation of signal_arrived.
* cygwait.cc (cancelable_wait): Ignore signal_arrived event if _my_tls 'sig'
element does not exist.
* exceptions.cc (_cygtls::interrupt_setup): Create signal_arrived if recipient
thread has not created it.
* sigproc.h (sigdelayed): Make symbol globally available.
* gendef (sigdelayed): Specifically zero incyg and stacklock.
* signal.cc (sigwaitinfo): Lock _my_tls and try harder to clean up signal
information.
Add regparm attribute.
* fhandler_socket.cc (fhandler_socket::read): Call recv_internal with
second parameter set to false.
(fhandler_socket::readv): Ditto.
(fhandler_socket::recvfrom): Ditto.
(fhandler_socket::recv_internal): Convert use_recvmsg from local
variable to parameter. Use as request for using WSARecvMsg. Only
fail if WSARecvMsg can't be loaded and wsamsg->Control.len > 0,
otherwise use WSARecv{From}. Restrict dwFlags to MSG_PEEK when using
WSARecvMsg.
(fhandler_socket::recvmsg): Prefer using WSARecvMsg. Change priority
of tests for not using WSARecvMsg. Call recv_internal with second
parameter set accordingly.
variable. Explain why. Add a muto to guard overwriting the changed_h
handle by multiple concurrent threads.
* path.h (class etc): Drop unused changed_h member.
problem.
* cygwin/winlean.h: Define constant which will be needed eventually. Remove
hack in favor of another hack.
* cygwin/lib/crt0.h: Use "winlean.h".
