2001-03-02'sort' race condition fixes.Jim Meyering
Defend against a DoS attack where someone else creates a temporary file with the same name as ours. Use mkstemp to do this, supplying our own mkstemp if the system doesn't have one. Also, fix a race condition during cleanup on hosts without sigaction. (NAME_MAX_IN_DIR): Remove. (sigprocmask, sigset_t): New macros, defined only on older hosts. (caught_signals): New var. (xtmpfopen, tempname): Removed. (create_temp_file): New function, combining the functions of the old xtmpfopen and tempname. All callers changed. Use mkstemp to create the file. (sighandler): On hosts without sigaction, ignore signals while cleaning up, instead of letting them interrupt cleanup. (main): Initialize caught_signals. On hosts with sigaction, block all caught signals while handling one. Remove duplicate code.

consistency with the other enum values.
2001-02-20(SI_OPTION): New enum value.Jim Meyering
(long_options): Use it instead of 'H' for --si. (decode_switches): Warn that -H will change soon. (usage): Likewise.

2001-02-20`ls -Fd symlink-to-directory' would print a trailing `/'Jim Meyering
Now it prints a trailing `@'. (gobble_file): Don't clobber lstat stats of command line arguments when using -d and -F (--directory and --classify) options.

2001-02-19Fix a race condition: freed storage accessed during a signal handler.Jim Meyering
(struct tempnode.next): Now volatile. (zaptemp): Free the file name after removing it from the temp list, not before, because a signal can arrive between the two actions and cleanup () traverses the list.

2001-02-19(jm_CHECK_ALL_HEADERS): Check for sys/resource.h.Jim Meyering

2001-02-19Check for input size, and do not overallocate memory.Jim Meyering
Also check for memory quotas. Revamp storage management so that line tables and character data are taken from the same buffer. Line tables are now in reverse order, since they grow down while the character data grow up. (<sys/resource.h>): Include if HAVE_SYS_RESOURCE_H. (struct rlimit, getrlimit): Define a replacement if RLIMIT_DATA is not defined. (RLIMIT_AS): Define to RLIMIT_DATA if not defined. (struct lines): Remove. (struct buffer): New members nlines, line_bytes, eof. Remove member newline_free; no longer needed, since the code no longer runs out of line table space. (SORTALLOC_MIN, SORTALLOC_DEFAULT_MIN): Remove. (sort_size): Renamed from sortalloc; now applies to the sum of the character data and the line table, not just the character data. (MIN_SORT_SIZE, INPUT_FILE_SIZE_GUESS): New macros. (linelength): remove. (specify_sort_size): Don't worry about the distinction between the character data and the line table; that is now the caller's responsibility. (default_sort_size): Return the value, instead of being executed for side effect. Return half of available memory, or 1/16 of total memory, whichever is greater; except do not exceed 1/2 of quota. (sort_buffer_size): New function. (initbuf): New arg LINE_BYTES. Ensure that the line array is properly aligned. Initialize the new set of struct buffer members. (buffer_linelim): New function. (fillbuf): Return int, not size_t, since the callers merely care whether the result is nonzero. New arg FILE so that error messages can report the file name. Keep track of eof. Initialize the line table too, taking its memory from the input buffer's memory; this subsumes the old findlines function and removes the need for worrying about running out of line table entries. (checkfp, mergefps, sortlines, merge, sort): Adjust to the new storage management regime, in particular the fact that line tables are now filled in by fillbuf and are in reverse order. (checkfp): Now takes char *, not const char *, since subroutines require that now. Rewrite to avoid lint and duplicate code. If line length alloc calculation overflows, simply allocate enough memory to hold the line. (mergefps): New arg FILES, used for buffer size calculation and error messages. Rewrite to avoid lint. Do not loop if savealloc*2 overflows. (mergefps, merge): Zap temporary files eagerly rather than lazily; this is needed because we now pass FILES to mergefps. (sortlines): Args now point at end of arrays, not at beginnings. (sort): Do not allocate temporary line array for sortlines; instead, take the space from the same buffer. (main): Adjust to sort_size and default_sort_size changes.
