| | | | | | | | | | | | | | | | | | | | * src/w32.c (fdutimens): Call utimensat instead of utime. (set_file_times): Function deleted. (convert_from_timespec): Renamed from convert_from_time_t and modified to accept 'struct timespec' argument instead of 'time_t'. (utimensat): Renamed from utime and modified to accept 'struct timespec [2]' argument and an additional argument FLAG. Emulate Posix 'utimensat'. Call 'convert_from_timespec'. (w32_copy_file): Call 'utimensat' instead of 'set_file_times'. * src/fileio.c (Fcopy_file) [WINDOWSNT]: Make the error message be identical to that on Posix platforms. * nt/inc/sys/stat.h (utimensat): Provide prototype. * nt/mingw-cfg.site (ac_cv_func_futimens) (gl_cv_func_futimens_works, ac_cv_func_utimensat) (gl_cv_func_utimensat_works): Override Gnulib tests. * nt/gnulib-cfg.mk (OMIT_GNULIB_MODULE_futimens) (OMIT_GNULIB_MODULE_utimensat): Disable these Gnulib modules.

| | | | | This catches some URLs I missed in my previous scan, or perhaps were added after the scan.
* Remove unneeded stuff from nt/inc/sys/time.hEli Zaretskii2017-05-151-23/+1
| | | | | | | | * nt/inc/sys/time.h (_TIMEVAL_DEFINED, struct timevat, timerisset) (timercmp, timerclear): Don't define. Instead, include the system header sys/time.h, and add only the interval timers stuff. This avoids compiler warnings about 'gettimeofday's prototype, and also avoids redefinition of macros from system headers.
* Remove gettimeofday from w32 sourcesEli Zaretskii2017-05-141-19/+0
| | | | | | * lib-src/ntlib.c (gettimeofday): * nt/inc/sys/time.h (gettimeofday, struct timezone): Remove unused function 'gettimeofday' and all of its supporting code.

(file_attributes): New function, with most of the old Ffile_attributes. (directory_files_internal, Ffile_attributes): Use it. (file_attributes, file_name_completion_stat): First arg is now fd, not dir name. All uses changed. Use fstatat rather than lstat + stat. (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p. * src/fileio.c: Include <allocator.h>, <careadlinkat.h>. (emacs_readlinkat): New function, with much of the old Ffile_symlink_p, but with an fd argument for speed. It uses readlinkat rather than careadlinkatcwd, so that it need not assume the working directory. (Ffile_symlink_p): Use it. * src/filelock.c (current_lock_owner): Use emacs_readlinkat rather than emacs_readlink. * src/lisp.h (emacs_readlinkat): New decl. (READLINK_BUFSIZE, emacs_readlink): Remove. * src/sysdep.c: Do not include <allocator.h>, <careadlinkat.h>. (emacs_norealloc_allocator, emacs_readlink): Remove.

(sys_wait): Remove prototype. * nt/config.nt (HAVE_SYS_WAIT_H): Define to 1. * src/w32proc.c (create_child): Don't clip the PID of the child process to fit into an Emacs integer, as this is no longer a restriction. (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by reaping only the process specified by PID argument, if that is positive. Use PID instead of dead_child to know which process to reap. Wait for the child to die only if WNOHANG is not in OPTIONS. (sys_select): Don't set dead_child. * src/sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion, as it is no longer needed. * src/process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions, no longer needed. (record_child_status_change): Remove the setting of record_at_most_one_child for the !WNOHANG case. 2012-11-03 Paul Eggert <eggert@cs.ucla.edu> Fix a race condition that causes Emacs to mess up glib (Bug#8855). This is a backport from the trunk. The symptom is a diagnostic "GLib-WARNING **: In call to g_spawn_sync(), exit status of a child process was requested but SIGCHLD action was set to SIG_IGN and ECHILD was received by waitpid(), so exit status can't be returned." The diagnostic is partly wrong, as the SIGCHLD action is not set to SIG_IGN. The real bug is a race condition between Emacs and glib: Emacs does a waitpid (-1, ...) and reaps glib's subprocess by mistake, so that glib can't find it. Work around the bug by invoking waitpid only on subprocesses that Emacs itself creates. * src/process.c (create_process, record_child_status_change): Don't use special value -1 in pid field, as the caller now must know the pid rather than having the callee infer it. The inference was sometimes incorrect anyway, due to another race. (create_process): Set new 'alive' member if child is created. (process_status_retrieved): New function. (record_child_status_change): Use it. Accept negative 1st argument, which means to wait for the processes that Emacs already knows about. Move special-case code for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of processes that have already been waited for, by testing and clearing new 'alive' member. (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change now does this internally. (handle_child_signal): Let record_child_status_change do all the work, since we do not want to reap all exited child processes, only the child processes that Emacs itself created. * src/process.h (Lisp_Process): New boolean member 'alive'.
| * | Fix the MS-Windows build.Eli Zaretskii2012-12-241-0/+1
| | | | | | | | | | | | | | | | | | nt/inc/sys/stat.h (S_ISMPX): Define to zero, to accommodate changes in lib/filemode.c that broke the MS-Windows build. Suggested by Andy Moreton <andrewjmoreton@gmail.com>.
| * | Support Posix ACL APIs on MS-Windows.Eli Zaretskii2012-12-171-0/+25

(SDDL_REVISION_1): Define if not already defined. (g_b_init_get_security_descriptor_dacl) (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd) (g_b_init_is_valid_security_descriptor) (g_b_init_set_file_security): New static flags. (globals_of_w32): Initialize them to zero. (SetFileSecurity_Name): New string constant.

| * | Speed up most calls to 'stat' and 'lstat' on MS-Windows.Eli Zaretskii2012-12-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | src/w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not try to get accurate owner and group information from NT file security APIs. This is to make most callers of 'stat' and 'lstat', which don't need that information, much faster. src/dired.c (Ffile_attributes) [WINDOWSNT]: Set w32_stat_get_owner_group to a non-zero value, to request accurate owner and group information from 'lstat'. nt/inc/sys/stat.h: Declare w32_stat_get_owner_group.
