2022-08-08Cygwin: fold common.din and x86_64.din into cygwin.dinCorinna Vinschen
We don't need a target-specific DEF file anymore Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2022-07-28Cygwin: rename __cygwin_environ and drop env redirection via cur_environ()Corinna Vinschen
Back in early Cygwin development a function based access to the environment was exported, the internal environ in Cygwin was called __cygwin_environ and cur_environ() was used to access the environment indirectly . The history of that necessity is not documented, but kept in i686 for backward compatibility. The x86_64 port eventually used __cygwin_environ directly and exported it as DATA under the usual name environ. We don't need the i686 workaround anymore, so just rename __cygwin_environ to environ, drop the cur_environ() macro and simply export environ under its own name.

2020-08-30Cygwin: Add C11 threads APICorinna Vinschen
Code taken from FreeBSD, which implements C11 threads as wrapper around pthreads. Fix up machine/_threads.h which is called from newlib's machine-independent threads.h to match Cygwin's pthreads types. Add the FreeBSD source files to libc subdir and take opportunity to define LIBC_OFILES var in Makefile. Add new symbols to common.din and sort symbols.

2020-08-30Cygwin: make pthread_yield available for internal usageCorinna Vinschen
In preparation of importing FreeBSDs stdthreads functions, change the way pthread_yield is exported, so that the symbol can be used internally as well. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2019-06-28Cygwin: Fix return value of sched_getaffinityMark Geisert
Have sched_getaffinity() interface like glibc's, and provide an undocumented internal interface __sched_getaffinity_sys() like the Linux kernel's sched_getaffinity() for benefit of taskset(1).
2019-06-24Cygwin: Implement sched_[gs]etaffinity()Mark Geisert
This patch set implements the Linux syscalls sched_getaffinity, sched_setaffinity, pthread_getaffinity_np, and pthread_setaffinity_np. Linux has a straightforward view of the cpu sets used in affinity masks. They are simply long (1024-bit) bit masks. This code emulates that view while internally dealing with Windows' distribution of available CPUs among processor groups.

2019-01-16Cygwin: timers: implement timerfdCorinna Vinschen
First cut of a timerfd implementation. Still TODO: - fork/exec semantics - timerfd_settime TFD_TIMER_CANCEL_ON_SET flag - ioctl(TFD_IOC_SET_TICKS) - bug fixes Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2019-01-14Cygwin: signal: implement signalfdCorinna Vinschen
First cut of a signalfd implementation. Still TODO: Non-polling select. This should mostly work as on Linux except for missing support for some members of struct signalfd_siginfo, namely ssi_fd, ssi_band (both SIGIO/SIGPOLL, not fully implemented) and ssi_trapno (HW exception, required HW support).

2018-07-25POSIX Asynchronous I/O support: other filesMark Geisert
Updates to misc files to integrate AIO into the Cygwin source tree. Much of it has to be done when adding any new syscalls. There are some updates to limits.h for AIO-specific limits. And some doc mods.

2018-06-27Cygwin: Implement pthread_tryjoin_np and pthread_timedjoin_npCorinna Vinschen
- Move pthread_join to thread.cc to have all `join' calls in the same file (pthread_timedjoin_np needs pthread_convert_abstime which is static inline in thread.cc) - Bump API version Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

There are two common sigpause variants, both of which take an int argument.

2016-08-23Add pthread_getname_np and pthread_setname_npJon Turney
This patch adds pthread_getname_np and pthread_setname_np. These were added to glibc in 2.12[1] and are also present in some form on NetBSD and several UNIXes. The code is based on NetBSD's implementation with changes to better match Linux behaviour. Implementation quirks: * pthread_setname_np with a NULL pointer segfaults (as linux) * pthread_setname_np returns ERANGE for names longer than 16 characters (as linux) * pthread_getname_np with a NULL pointer returns EFAULT (as linux) * pthread_getname_np with a buffer length of less than 16 returns ERANGE (as linux) * pthread_getname_np truncates the thread name to fit the buffer length. This guarantees success even when the default thread name is longer than 16 characters, but means there is no way to discover the actual length of the thread name. (Linux always truncates the thread name to 16 characters) * Changing program_invocation_short_name changes the default thread name (on linux, it has no effect on the default thread name) I'll leave it up to you to decide if any of these matter. This is implemented via class pthread_attr to make it easier to add pthread_attr_[gs]etname_np (present in NetBSD and some UNIXes) should it ever be added to Linux (or we decide we want it anyway).

2016-08-20Implement missing POSIX function nl_langinfo_lCorinna Vinschen
Change nl_langinfo to nl_langinfo_l using locale given as argument. Remove outdated TRANSITION_PERIOD_HACK. The codeset is stored in the locale for quite some time now. For !MB_CAPABLE targets, just return "US_ASCII" as codeset. Implement nl_langinfo by calling nl_langinfo_l. Export nl_langinfo_l from Cygwin DLL and bump minor API version number.
