* Cygwin: Define FSCTL_PIPE_FLUSHCorinna Vinschen2018-03-071-0/+3
| | | | | | This fsctl might come in handy at one point... Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Cygwin: AF_UNIX: Implement read, readv, recvfrom, write, writev, sendtoCorinna Vinschen2018-03-071-20/+88
| | | | | | All of these functions just call recvfrom/sendmsg which are still TODO Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Cygwin: AF_UNIX: fix accept behaviourCorinna Vinschen2018-03-071-15/+37
| | | | | | | | | * Use correct cygwait/WFSO invocation to not die on cancel and signals uncontrolled. * Manage io handles under io_lock. * Copy peer address to user space under SEH to avoid a resource leak. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Cygwin: AF_UNIX: make sure connect wait thread is cleanly interruptibleCorinna Vinschen2018-03-072-8/+49
| | | | | | | | | | | | | | Using TerminateThread potentially leaks resources. In our case, the connect wait thread may be forcefully terminated after having successfully opened a client side pipe handle. If this occurs, we have a stale pipe server instance, so the pipe will never be closed as long as the process lives. Avoid this by changing the npfs handle to non-blocking, so we can wait on a termination event object from inside the thread itself and cleanly exit from the thread instead of terminating.

* Cygwin: AF_UNIX: some pipe errors may have multiple status codesCorinna Vinschen2018-03-071-3/+26
| | | | | | | | Depending on the exact circumstances, some erros are indicated by different status codes. Add helper macros to handle them together. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Cygwin: AF_UNIX: fix creation of npfs handleCorinna Vinschen2018-03-073-25/+23
| | | | | | | | | The handle to the device is never needed. As the name impies, FSCTL_PIPE_WAIT works on the file system, not on the device level. Drop opening the device and make sure to open only one handle to NPFS. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Cygwin: AF_UNIX: Add create_event helper and use throughoutCorinna Vinschen2018-03-071-15/+25

* RTEMS: Use int for _CLOCKID_T_Sebastian Huber2018-03-061-0/+3
| | | | | | | | | Linux and FreeBSD use int as well. In addition, this fixes an Ada incompatiblity problem on 64-bit targets. See also GCC: gcc/ada/libgnarl/s-osinte__rtems.ads Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
* Make _CLOCKID_T_ system configurableSebastian Huber2018-03-061-0/+3
| | | | | | | Let systems optionally provide the _CLOCKID_T_ type via <machine/_types.h>. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
* Cygwin: move sun_name_t constructors into fhandler_socket_unix.ccCorinna Vinschen2018-03-052-12/+19
| | | | | | | | | | They are only used there anyway and it allows to use the AF_UNIX macro without tweaking header files. While at it, improve both constructors. The default constructor now creates the name of an unnamed socket, the constructor taking parameters carefully checks its input. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Cygwin: drop debug_printf statement from start_transactionCorinna Vinschen2018-03-051-4/+1
| | | | | | | start_transaction is now defined in ntdll.h and we can't rely on debug_printf being available Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Locale modifier @cjkwide to adjust ambiguous-width in non-CJK localesThomas Wolff2018-03-051-16/+23
| | | | | | | | | | Locale modifier @cjkwide makes Unicode "ambiguous width" characters wide. So ambiguous width characters can be enforced to have width 2 even in non-CJK locales. This gives e.g. users of "Powerline symbols" the opportunity to adjust their width to the desired behaviour (and the behaviour apparently expected by some tools) without having to set a CJK locale and without losing consistence of terminal character width with wcwidth/wcswidth locale width.
* Cygwin: AF_UNIX: drop try/except block in bind methodCorinna Vinschen2018-03-021-27/+21

* Cygwin: add transform_chars_af_unix helperCorinna Vinschen2018-03-022-2/+13
| | | | | | | | | This function is going to be used for transposing sun_path of abstract sockets. This also adds a transposition of the NUL character to tfx_chars since NUL-bytes in abstract socket names are perfectly valid. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

| | | | | | | | | | * check_reparse_point_target returns a path flag mask, rather than just 1. Return PATH_SYMLINK | PATH_REP for symlinks and directory mount points, PATH_SOCKET | PATH_REP for AF_UNIX sockets. * Define Cygwin AF_UNIX socket reparse tag and GUID in ntdll.h.

* Cygwin: reduce size of fhandler_cygdrivenewlib-snapshot-20180226Corinna Vinschen2018-02-262-27/+26
| | | | | | | | | | | fhandler_cygdrive has a size of 696 bytes on x86_64, while the next biggest fhandler type, fhandler_pty_master, is 584 bytes. The members responsible for the size are private to opendir/readdir/closedir usage. fhandler_disk_file stores private readdir data in DIR->__d_internal instead. Use equivalent method with fhandler_cygdrive. This drops the size to 464 bytes. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
