2024-08-19Cygwin: pipe: do short writes only once in nonblocking case tooCorinna Vinschen1-2/+1
If a nonblocking write requires short writes, just try it once as in the blocking case. After all, we are nonblocking, so don't loop unnecessarily. Fixes: 170e6badb621 ("Cygwin: pipe: improve writing when pipe buffer is almost full") Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2024-08-18Cygwin: pipe: improve writing when pipe buffer is almost fullCorinna Vinschen3-18/+75
So far fhandler_pipe_fifo::raw_write always returns -1/EINTR if a signal arrived. Linux does not do that if there's still space left in the pipe buffer. The Linux buffer handling can't be emulated by Cygwin, but we can do something similar which makes it much more likely to still write successfully even if the buffer is almost full. Utilize pipe_data_available to return valid pipe buffer usage to raw_write, allowing a more sophisticated way to fill the buffer while maintaining comaptibility with non-Cygwin pipes.

2024-08-18Cygwin: select: set pipe writable only if PIPE_BUF bytes leftCorinna Vinschen1-9/+9
Linux select(2) returns the pipe as writable if at least one free page (4K onl most systems) is left in a page-oriented buffer handling. This is the same as PIPE_BUF. Emulate this behaviour by only returning the pipe as writable if at least 4K space is left in the buffer. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2024-08-18Cygwin: pipe: handle signals explicitely in raw_writeCorinna Vinschen1-3/+12

2024-08-07Cygwin: asm/socket.h: drop outdated castsCorinna Vinschen1-2/+2
The _IOR anbd _IOW macros cast the sizeof of their third arg uselessly to long. The _IO definitions have been taken from BSD in 1995 and never changed again. The fact that the sizeof() gets cast to long is probably a remnant from the past when the stuff was supposed to be used on 16 bit machines, but the value was supposed to be 32 bit. Given that the values are not supposed to be ever bigger than 32 bit, we drop the (long) cast. Compare with current FreeBSD, which does not cast at all.

2024-07-09libc/arm: add missing .cfi_sectionsClément Chigot7-0/+7
The modifications added by the series "M-profile PACBTI-enablement" (see 9d6b00511e50a54d2472d11f75f7c0f2b4a98b24) have introduced a couple of .cfi_* instructions. Like for e6459123e497409a9e3d845c39829a9602ba55a4, these instructions create object files which contain .eh_frame sections. However, ARM uses its own unwind info format, not .eh_frame, which is generated by ARM-specific directives, not .cfi_*. The .eh_frame sections are useless, but also not removed by strip and may be harmful with some linker scripts. Adding ".cfi_sections .debug_frame" (as in glibc) moves the generated directives towards .debug_frame instead of .eh_frame. Making them easier to handle. * libc/machine/arm/aeabi_memmove-thumb2.S: Use .cfi_sections .debug_frame. * libc/machine/arm/aeabi_memset-thumb2.S: Likewise. * libc/machine/arm/memchr.S: Likewise. * libc/machine/arm/memcpy-armv7m.S: Likewise. * libc/machine/arm/setjmp.S: Likewise. * libc/machine/arm/strlen-armv7.S: Likewise. * libc/machine/arm/strlen-thumb2-Os.S: Likewise.

More, there are some subtle differences between the <atomic> C++ header, and C11+ stdatomic.h provided features.

2024-07-09sys/sys: further adoption of SPDX licensing ID tags.Pedro F. Giffuni1-0/+2
Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task.

We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.
2024-07-09Cygwin: console: Fix for GNU screen/tmux in ConEmuTakashi Yano1-1/+18
If the master process of GNU screen or tmux is started in ConEmu and ConEmu is closed, reattaching to the GNU screen/tmux in another console will not work correctly. This is because the ConEmu master process was already closed even though some console APIs are hooked by ConEmuHk64.dll to communicate with ConEmu master process. With this patch, to make them unhooked, DllMain() of ConEmuHk64.dll is called with DLL_PROCESS_DETACH. Fixes: 3721a756b0d8 ("Cygwin: console: Make the console accessible from other terminals.")

2024-07-09Cygwin: console: Fix race issue on allocating console simultaneously.Takashi Yano6-56/+57
Previously, if two or more processes request to allocate a console at the same time, the same device number could be accidentally allocated. This patch fixes the issue by creating a named mutex (input_mutex) and checking if GetLastError() is ERROR_ALREADY_EXIST or not to ensure the unit number will be allocated in an atomic way. Thanks to this, EnumWindow() is not necessary anymore to scan console units. This also makes minor device numbers unique and console devices visible across sessions. This disallows duplicated device number for different sessions, so the MAX_CONS_DEV has been increased from 64 to 128. Additionally, the console allocation and scanning will be faster as a side effect of eliminating EnumWindows().

2024-07-03Cygwin: console: Fix conflict on shared names between sessions.Takashi Yano2-4/+14
Previously, shared names in the console were created using get_minor(). However, get_minor() was not unique to the console across sessions. This is because EnumWindows(), which is used to look for console windows, cannot enumerate windows across sessions. This causes conflict on the shared names between sessions (e.g. sessions of different users, different services, a service and a user session, etc.). With this patch, GetConsoleWindow() is used instead of get_minor(). GetConsoleWindow() has been used for the name of shared memory, which should be unique to each console.

2024-07-01Cygwin: pty: Avoid client deadlock when pty master stops to read.Takashi Yano2-3/+26
Previsouly, the following commands hangs: mintty -e timeout 1 dash -c 'yes aaaaaaaaaaaaaaaaaaaaaaaaa | cat' The mechanism is as follows. When the child process (timeout) is terminated, mintty seems to stop reading pty master even if yes or cat still alive. If the the pipe used to transfer output from pty slave to pty master is full due to lack of master reader, WriteFile() to the pipe is blocked. WriteFile() cannot be canceled by cygwin signal, therefore, pty slave hangs. This patch avoids hanging by checking pipe space before calling WriteFile() and prevents writing data more than space.
