2026-05-26ARRAYELTS → countofPaul Eggert
C2y will standardize countof as the macro that Emacs uses the name ARRAYELTS for. Switch to the standard name, which is supported by GCC 16+, by Clang 21, and by the Gnulib stdcountof-h module already in use for compilers that do not support countof. Also, use countof in a few places where we missed using ARRAYELTS. * admin/coccinelle/arrayelts.cocci: Suggest countof, not ARRAYELTS. * admin/merge-gnulib (GNULIB_MODULES): Add stdcountof-h, as it is now a direct rather than an indirect dependency. * exec/trace.c, src/lisp.h, src/sfnt.c: Include <stdcountof.h>. (ARRAYELTS): Remove. All uses replaced by countof. * lib-src/ebrowse.c, lib-src/etags.c, lib-src/make-docfile.c: * lib-src/seccomp-filter.c, lwlib/lwlib-Xaw.c: Prefer <stdcountof.h> and countof to doing things by hand.

2025-03-14Increase FD_SETSIZE on Windows to support more subprocessesYue Yi
Earlier versions of Emacs were limited to at most 32 subprocesses or network connections on Windows due to the 64-object limit imposed by WaitForMultipleObjects. To overcome this, a simple waiting thread pool is implemented, allowing Emacs to efficiently wait on up to 2048 objects. Each thread in the pool can wait on up to 63 objects, and a total of 32 threads are used, together with the main thread, to expand the waiting capability. This enables Emacs to support approximately 1024 subprocesses, which is comparable to the 'pty' method on GNU/Linux when using the default FD_SETSIZE of 1024. To minimize overhead, the threads remain active instead of being frequently created and destroyed, reducing unnecessary system resource consumption. Idle threads can be terminated after a period of inactivity to free up memory. * src/w32.h (FD_SETSIZE): Change from 64 to 2048. * src/w32.c (term_ntproc): Call 'free_wait_pool' to free waiting threads. * src/w32proc.c (WFO_ABANDONED, WFO_TIMEOUT, WFO_FAILED) (WFO_MAX_WAIT): New macros. (wait_objects_context, wait_objects_pool, wait_objects_info): New structures for managing the thread pool. (wait_objects_pool, wait_objects_info): New static variables for managing the thread pool. (wait_objects_thread, start_wait_objects, stop_wait_objects) (end_wait_and_return, shrink_wait_pool, free_wait_pool): New functions for waiting and managing the thread pool. (wait_for_objects, msg_wait_for_objects): New functions as replacements for WaitForMultipleObjects and MsgWaitForMultipleObjects. (wait_pid): Use 'wait_for_objects' and new macros. (sys_select): Make some variables static to avoid stack allocation. Use 'wait_for_objects', 'msg_wait_for_objects', and the new macros.

A new Windows-specific function for validating process ID is introduced that does TRT with possibly negative PID values returned by 'getpid' on Windows 9X and also with values larger than INT_MAX, since PID on Windows is actually an unsigned 32-bit value. * src/w32proc.c (w32_valid_process_id): New function. * src/w32common.h (VALID_PROCESS_ID): Define for WINDOWSNT. * src/filelock.c [WINDOWSNT]: Include w32common.h.

* src/coding.c (CHECK_FIXNAT_CAR, CHECK_FIXNAT_CDR): * src/lisp.h (CHECK_FIXNUM_CAR, CHECK_FIXNUM_CDR): Remove. All uses removed. These seem to have been based on the assumption that the argument cons needs to be modified, an assumption that is incorrect for fixnums.

2018-08-27Improve bignum support for system typesPaul Eggert
Use bignums when Emacs converts to and from system types like off_t for file sizes whose values can exceed fixnum range. Formerly, Emacs sometimes generted floats and sometimes ad-hoc conses of integers. Emacs still accepts floats and conses for these system types, in case some stray Lisp code is generating them, though this usage is obsolescent. * doc/lispref/files.texi (File Attributes): * doc/lispref/hash.texi (Defining Hash): * doc/lispref/nonascii.texi (Character Sets): * doc/lispref/os.texi (User Identification): * doc/lispref/processes.texi (System Processes): * etc/NEWS: Document changes. * src/bignum.c (mpz_set_uintmax, make_biguint) (mpz_set_uintmax_slow, bignum_to_intmax, bignum_to_uintmax): New functions.
