2024-09-02Cygwin: pipe: Fix a regression that raw_write() slows downTakashi Yano2-2/+7
After the commit 7f3c22532577, writing to pipe extremely slows down. This is because cygwait(select_sem, 10, cw_cancel) is called even when write operation is already completed. With this patch, the cygwait() is called only if the write operation is not completed. Addresses: https://cygwin.com/pipermail/cygwin/2024-August/256398.html Fixes: 7f3c22532577 ("Cygwin: pipe: handle signals explicitely in raw_write") Reported-by: Jim Reisert AD1C <jjreisert@alum.mit.edu> Reviewed-by: Corinna Vinschen <corinna@vinschen.de> Signed-off-by: Takashi Yano <takashi.yano@nifty.ne.jp>
2024-08-31Cygwin: console: Disable cons_master_thread in win32-input-modeTakashi Yano3-2/+14
When win32-input-mode (which is supported by Windows Termainal) is set by "\033[?9001h", cons_master_thread does not work properly and consumes larger and larger memory space. This is because sending event by WriteConsoleInput() is translated into the sequence that is used by win32-input-mode. Due to this behaviour, write-back of the INPUT_RECORDs does not work as expected. With this patch, cons_master_thread is disabled on win32-input-mode where the signal keys such as Ctrl-C, Ctrl-Z etc. never comes. Addresses: https://cygwin.com/pipermail/cygwin/2024-August/256380.html Fixes: ff4440fcf768 ("Cygwin: console: Introduce new thread which handles input signal.")

2024-08-22locales: Fix definition of lc_messages_T::codesetCorinna Vinschen1-1/+3
nl_langinfo_l accesses lc_messages_T::codeset as soon as __HAVE_LOCALE_INFO__ is defined, but codeset only exists if __HAVE_LOCALE_INFO_EXTENDED__ is defined. Fix this by defining lc_messages_T::codeset depending on __HAVE_LOCALE_INFO__.

2024-08-22nl_langinfo_l: drop erroneus messages::codeset entryCorinna Vinschen1-1/+0
The nl_ext array contains offsets into the extended info of locale structures, the index being equivalent to the nl_item values in langinfo.h. For the lc_messages_T struct, nl_ext erroneusly contains an entry for the codeset member, which is in fact not part of the extended info in nl_item. However, due to that, the offsets for subsequent entries are off by one. Fix this by dropping the messages::codeset entry from nl_ext.

2024-08-21arc64: Add port for Synopsys DesignWare ARCv3 ISAYuriy Kolerov33-528/+4639
Synopsys ARCv3 ISA includes 32-bit ARC HS5x targets and 64-bit ARC HS6x targets. Both CPU families are placed in "arc64" subdirectories as it done for GCC port. Target name arc64 is used for historical reasons and Synopsys ARCv3 baremetal toolchains contain multilib configurations both for 32-bit and 64-bit families. arc32 target name is reserved for 32-bit ARC HS5x targets in case of non-multilib 32-bit builds. Note that libgloss libraries for ARCv3 are compatible with libgloss for ARCv1/2. Thus, Makefile.inc for libgloss uses sources from libgloss/arc directory except crtX.S files.

2024-08-19Cygwin: pipe: do short writes only once in nonblocking case tooCorinna Vinschen1-2/+1

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.

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.
