Paul Eggert eeb96e1a 2006-09-16T19:58:25 * lib/dirchownmod.c: Don't include fcntl.h; no longer needed. (dirchownmod): New arg FD. All callers changed. Use FD rather than opening the directory ourself, as opening is now the caller's responsibility. * lib/dirchownmod.h: Likewise. * lib/mkancesdirs.c: Include <sys/types.h>, for portability to older hosts that require <sys/types.h> before <sys/stat.h>. Include fcntl.h, savewd.h, and unistd.h, not dirname.h and stat-macros.h. (test_dir): Remove. (mkancesdirs): Return length of prefix of FILE that has already been made, or -2 if there is a child doing the work. Redo algorithm so that it is O(N) rather than O(N**2). Optimize away ".", and treat ".." specially since it might stray back into already-created areas. Use a subprocess if necessary. New arg WD; all users changed. MAKE_DIR function should now return 1 if it creates a directory that is not readable. Return -2 if a child process is spun off. * lib/mkancesdirs.h: Include <stddef.h>, for ptrdiff_t. Adjust signature to match code. * lib/mkdir-p.c: Include dirname.h, for IS_ABSOLUTE_FILE_NAME. (make_dir_parents): Use a subprocess if necessary. New arg WD; all users changed. * lib/savewd.c, lib/savewd.h: New files. * m4/savewd.m4: New file. * modules/mkancesdirs (Depends-on): Add fcntl. * modules/savewd: New file. * MODULES.html.sh (File system functions): Add savewd.
Paul Eggert 5f531596 2006-07-17T06:06:48 Import from coreutils. * MODULES.html.sh: Add mkancestors. * modules/mkancesdirs: New module. * modules/mkdir-p (Files): Remove lib/chdir-safer.c, lib/chdir-safer.h, lib/same-inode.h, m4/afs.m4, m4/chdir-safer.m4. The chdir-safer and afs files are now orphans; I'll remove them unless someone speaks up. Add lib/dirchownmod.c, lib/dirchownmod.h. (Depends-on): Remove alloca, chown, save-cwd, dirname. Add lchown, mkancesdirs. (Maintainer): Add self. * lib/dirchownmod.c, lib/dirchownmod.h: * lib/mkancesdirs.c, lib/mkancesdirs.h: New files. * lib/mkdir-p.c: Don't include alloca.h, stdio.h, sys/types.h, unistd.h, string.h, chdir-safer.h, dirname.h, lchmod.h, lchown.h, save-cwd.h. Instead, include dirchownmod.h and mkancesdirs.h. (make_dir_parents): New args MAKE_ANCESTOR, OPTIONS, ANNOUNCE, MODE_BITS. Remove options VERBOSE_FMT_STRING, CWD_ERRNO. All callers changed. Revamp internals significantly, by not attempting to create directories that are temporarily more permissive than the final results. Do not attempt to use save_cwd/restore_cwd; it isn't worth it for mkdir and install. This removes some race conditions, fixes some bugs, and simplifies things. Use new dirchownmod function to do owner and mode changes. * lib/mkdir-p.h: Likewise. * lib/modechange.c (octal_to_mode): New function. (struct mode_change): New member mentioned. (make_node_op_equals): New arg mentioned. All callers changed. (mode_compile): Keep track of which mode bits the user has explicitly mentioned. (mode_adjust): New arg DIR, so that we implement the X op correctly. New arg PMODE_BITS, to keep track of which mode bits the user mentioned; it treats S_ISUID and S_ISGID speciall. All callers changed. * lib/modechange.h: Likewise. * mkancesdirs.m4: New file. * mkdir-p.m4 (gl_MKDIR_PARENTS): Mention dirchownmod.c, dirchownmod.h. Don't require AC_FUNC_ALLOCA, gl_AFS, gl_CHDIR_SAFER; no longer needed. Require gl_FUNC_LCHOWN, since dirchownmod.c needs it.
