* etc/NEWS: Document this. * nt/inc/unistd.h (O_NOFOLLOW): New macro. * src/filelock.c: Include <c-ctype.h>. (MAX_LFINFO): New top-level constant. (lock_info_type): Remove members pid, boot_time. Add members at, dot, colon. Change user member to be the entire buffer, not a pointer. This allows us to handle the case where a foreign pid or boot time exceeds the local range. All uses changed. (LINKS_MIGHT_NOT_WORK): New constant. (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing. (defined_WINDOWSNT): Remove. (MAKE_LOCK_NAME, file_in_lock_file_name): Always use .#FILE (not .#-FILE) for the file lock, even if it is a regular file. (rename_lock_file): New function. (create_lock_file): Use it. (create_lock_file, read_lock_data): Prefer a symbolic link for the lock file, falling back on a regular file if symlinks don't work. Do not try to create symlinks on MS-Windows, due to security hassles. Stick with POSIXish functions (open, read, write, close, fchmod, readlink, symlink, link, rename, unlink, mkstemp) when creating locks, as a GNUish host may be using a Windowsish file system, and cannot use MS-Windows-only system calls. Fall back on mktemp if mkstemp doesn't work. Don't fail merely because of a symlink-contents length limit in the current file system; fall back on regular files. Increase the symlink contents length limit to 8 KiB, this should be big enough for any real use and doesn't crunch the stack. (create_lock_file, lock_file_1, read_lock_data): Simplify allocation of lock file buffers now that they fit in 8 KiB. (lock_file_1): Return error number, not bool. All callers changed. (ELOOP): New macro, if not already defined. (read_lock_data): Return size of lock file contents, not Lisp object. All callers changed. Handle a race condition if some other process replaces a regular-file lock with a symlink lock or vice versa, while we're trying to read the lock. (current_lock_owner): Parse contents more carefully, to help avoid confusing a regular-file lock with some other application's use of the file. Check for lock file contents being too long, or not parsing correctly. (current_lock_owner, lock_file): Allow foreign pid and boot times that exceed the local range. (current_lock_owner, lock_if_free, lock_file): Simplify allocation of lock file contents. * src/w32.c (sys_rename_replace): New function, containing most of the contents of the old sys_rename. (sys_rename): Use it. (fchmod): New dummy function. * src/w32.h (sys_rename_replace, fchmod): New decls. Fixes: debbugs:13807 |
