* Fix various OS-related commentsCorinna Vinschen2016-06-241-2/+2

* Handle up to 63 partitions per driveCorinna Vinschen2016-06-231-11/+6
| | | | | | | | | | | | | | Revamp device parsing code. Introducing support for more partitions into the shilka-generated parser has the unfortunate side-effect of raising the size of the DLL by almost 2 Megs. Therefore we split out the handling for /dev/sdXY devices into a tiny bit of hand-written code. While at it, remove some unused cruft from devices.* and generally clean up the device class to provide access methods instead of direct access to members.

Use new copyto() fhandler method to copy from/to found archetype. * fhandler.h: Throughout, delete size(), add copyout, clone, and fhandler_* (void *) methods. (fhandler_base::reset): Rename from operator =(). (fhandler_termios::is_dev_tty): Delete. (fhandler_termios): change "protected" region to "private". (fhandler_termios::is_dev_tty): Delete.

(fhandler_pty_master::~fhandler_pty_master): Declare new method. (fhandler_nodevice): Remove commented out function declaration. * fhandler_console.cc: Use get_ttyp() instead of tc() throughout. (fhandler_console::dup): Define new function to set controlling ctty on dup, as appropriate. (fhandler_console::ioctl): Reflect ioctl_termios name change. (fhandler_console::setup): Rename from get_tty_stuff. (fhandler_console::open_setup): Reflect argument change in pinfo::set_ctty. (fhandler_console::fhandler_console): Set _tc here. * fhandler_termios.cc (handler_termios::ioctl): Rename. Take a void * arg like other ioctl functions. * fhandler_tty.cc (fhandler_pty_slave::dup): Call myself->set_ctty to potentially reset the controlling terminal. (fhandler_pty_slave::ioctl): Reflect name/arg change for ioctl_termios. (fhandler_pty_slave::fhandler_pty_slave): Take a "unit" argument. Call setup() here so that we will know the unit number of this fhandler as soon as possible. Set the unit as appropriate. (handler_pty_master::open): Move most stuff to constructor and open_setup. (handler_pty_slave::open_setup): Reflect argument change in pinfo::set_ctty. (handler_pty_master::open_setup): Define new function.

(fhandler_pty_master::~fhandler_pty_master): Define new method. (fhandler_pty_master::ioctl): Reflect name/arg change for ioctl_termios. (fhandler_pty_master::setup): Allocate tty here. Rely on handles being returned from allocated test rather than opening them here. Avoid setting _need_nl here since it is already zeroed in the constructor. Set up device information with DEV_TTYM_MAJOR. * path.h (path_conv &operator =): Take a const argument. (path_conv::dup): Ditto. (pathconv_arg::PC_OPEN): New enum. (pathconv_arg::PC_CTTY): Ditto.

(path_conv::isctty_capable): Ditto. * path.cc (path_conv::check): Set PATH_OPEN and PATH_CTTY as appropriate. * pipe.cc (fhandler_pipe::open): Use copyto to copy pipe handle. * syscall.cc (open): Reinstate fd > 2 check to disallow resetting ctty on non-std* handles. * tty.cc (tty_list::allocate): Pass out handles for allocated tty. use `not_allocated' to find unallocated ttys. Avoid keeping the lock since the allocation of the tty should be sufficient to prevent multiple access. (tty::not_allocated): Clarify comment. Rename. Return handles when an unused tty is found. Simply test for existing tty. (tty::exists): Rewrite to use `not_allocated'. * tty.h (NTTYS): Reset down to actual number supported by devices.in. (tty::not_allocated): Declare new function. (tty_list::allocate): Pass out read/write tty handles. Zero them when not found. * fhandler_proc.cc: Reflect name change from FH_PTYM -> FH_PTMX. * pinfo.h (pinfo::set_ctty): Reduce/reorder arguments passed in. * pinfo.cc (pinfo::set_ctty): Ditto. Just use tc() built into the passed-in fhandler_termios pointer. Return true if ctty is assigned. * syscalls.cc (open): Call build_fh_pc with PC_OPEN flag. Set PC_CTTY if appropriate. (stat_worker): Remove is_dev_tty () stuff.
* * cygwin.din: Remove some _tc* exports. Add tcgetsid().Christopher Faylor2011-10-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * dtable.cc (fh_alloc): Revert ill-advised setting of major/minor. Use new is_dev_tty to remember that this device was opened as /dev/tty. * fhandler.cc (fhandler_base::fstat): Remove leftover debugging statement. (fhandler_base::tcgetsid): New function. * fhandler.h ((fhandler_base::tcgetsid): Declare new function. (fhandler_base::is_dev_tty): Ditto. (fhandler_termios::opened_as_dev_tty): Declare new field.
