2022-08-05Cygwin: Reorganize cygwin source dirCorinna Vinschen1-135/+0
Create subdirs and move files accordingly: - DevDocs: doc files - fhandler: fhandler sources, split fhandler.cc into base.cc and null.cc - local_includes: local include files - scripts: scripts called during build - sec: security sources Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2021-01-20Cygwin: console: Fix "Bad file descriptor" error in script command.Takashi Yano via Cygwin-patches1-0/+7
- After the commit 72770148, script command exits occasionally with the error "Bad file descriptor" if it is started in console on Win7 and non-cygwin process is executed. This patch fixes the issue.
2020-03-23Cygwin: serial: use per call OVERLAPPED structsCorinna Vinschen1-1/+20
Sharing the OVERLAPPED struct and event object in there between read and select calls in the fhandler might have been a nice optimization way back when, but it is a dangerous, not thread-safe approach. Fix this by creating per-fhandler, per-call OVERLAPPED structs and event objects on demand. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2020-03-22Cygwin: serial: revamp overlapped IO in read and selectCorinna Vinschen1-8/+1
Get rid of WaitCommEvent and using overlapped_armed to share the same overlapped operation between read and select. Rather, make sure to cancel the overlapped IO before leaving any of these functions. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2020-01-13Cygwin: select: Speed up select() call for pty, pipe and fifo.Takashi Yano1-0/+1
- The slowing down issue of X11 forwarding using ssh -Y, reported in https://www.cygwin.com/ml/cygwin/2019-12/msg00295.html, is due to the change of select() code for pty in the commit 915fcd0ae8d83546ce135131cd25bf6795d97966. cygthread::detach() takes at most about 10msec because Sleep() is used in the thread. For this issue, this patch uses cygwait() instead of Sleep() and introduces an event to abort the wait. For not only pty, but pipe and fifo also have the same problem potentially, so this patch applies same strategy to them as well.
2019-09-05Cygwin: pty: Fix select() with pseudo console support.Takashi Yano1-0/+2
- select() did not work correctly when both read and except are polled simultaneously for the same fd and the r/w pipe is switched to pseudo console side. This patch fixes this isseu.
2019-08-18Cygwin: select: revamp non-polling code for signalfdCorinna Vinschen1-9/+2
Rather than waiting for signalfd_select_wait in a thread, which is racy, create a global event "my_pendingsigs_evt" which is set and reset by wait_sig depending only on the fact if blocked signals are pending or not. This in turn allows to WFMO on this event in select as soon as signalfds are present in the read descriptor set. Select's peek and verify will then check if one of the present signalfds is affected. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2019-03-27Cygwin: FIFO: update selectKen Brown1-0/+7
Add static functions peek_fifo, thread_fifo, start_thread_fifo, and fifo_cleanup to select.cc. These are based on the corresponding pipe functions, the main difference being that peek_fifo loops through the connected clients to see if any of them have data available for reading. Add the fhandler_fifo methods select_read, select_write, and select_except. Add accessor methods get_nclients, get_handle, and is_connected that are needed by peek_fifo.
2019-01-14Cygwin: signalfd: implement non-polling selectCorinna Vinschen1-2/+10
Allow the signal thread to recognize we're called in consequence of select on a signalfd. If the signal is part of the wait mask, don't call any signal handler and don't remove the signal from the queue, so a subsequent read (or sigwaitinfo/sigtimedwait) still gets the signal. Instead, just signal the event object at _cygtls::signalfd_select_wait for the thread running select. The addition of signalfd_select_wait to _cygtls unearthed the alignment problem of the context member again. To make sure this doesn't get lost, improve the related comment in the header file so that this (hopefully) doesn't get lost (again). Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2019-01-14Cygwin: select: always store the running thread's TLS into select_recordCorinna Vinschen1-1/+3
This allows select threads to access our current tls if required. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2016-06-23Switching the Cygwin DLL to LGPLv3+, dropping commercial buyout optioncygwin-2_5_2-releaseCorinna Vinschen1-3/+0
Bump GPLv2+ to GPLv3+ for some files, clarify BSD 2-clause. Everything else stays under GPLv3+. New Linking Exception exempts resulting executables from LGPLv3 section 4. Add CONTRIBUTORS file to keep track of licensing. Remove 'Copyright Red Hat Inc' comments. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
