This is for + efficiency, so that we don't call zaptemp so often. + All callers changed. + (sort): Don't create array in reverse order, since the list of + temporaries is now in the correct order. + + (zaptemp): Protect against race condition: if 'sort' is + interrupted in the middle of zaptemp, it might unlink the + temporary file twice, and the second time this happens the file + might already have been created by some other process. + + (zaptemp): Warn if a temporary file is not removed. + + (create_temp_file): Use offsetof for clarity. + (die): Move it up earlier, to clean up the code a bit. + + * src/pr.c (strtoumax): Declare if not declared. + (skip_to_page, first_page_number, last_page_number, page_number, + first_last_page, print_header): + Use uintmax_t for page numbers. + (first_last_page): Remove unnecessary forward declaration. + Do not modify arg (it is now a const pointer). + Return a true if successful, false (without print a diagnostic) + otherwise. + (main): If +XXX does not specify a valid page range, treat it + as a file name. This follows the response to Open Group XCU ERN 41 + <http://www.opengroup.org/sophocles/show_mail.tpl?source=L&listname=austin-group-l&id=7717>, + which says the behavior is allowed. + (skip_to_page): When starting page number exceeds page count, + print both numbers in the diagnostic. + (print_header): Detect page number overflow. + +2004-11-07 Jim Meyering <jim@meyering.net> + + * src/uname.c [__APPLE__]: Include <mach/machine.h> and <mach-o/arch.h>. + (main) [__APPLE__]: Get the processor type via syscall rather than + hard-coding "powerpc".

Move most of the code to.... + (avoid_trashing_input): New function. + (merge): Avoid some silly merges, e.g., copying a single file to + a temporary file when there are exactly 17 input files to merge. + Take a count of temporary files rather than a max_merge arg. + All uses changed. + +2004-11-06 Jim Meyering <jim@meyering.net> + + * src/sort.c (xfclose): Don't close stdout here (just flush it), + since close_stdout now closes stdout unconditionally. + +2004-11-05 Paul Eggert <eggert@cs.ucla.edu> + + * src/sort.c (inittables, sort_buffer_size, getmonth, mergefps, + first_same_file, merge, sort, main): Use size_t for indexes to arrays. + This fixes some unlikely havoc-wreaking bugs (e.g., more than INT_MAX + temporary files). + (getmonth, keycompare, compare): Rewrite to avoid need for alloca, + thus avoiding unchecked stack overflow in some cases. As a side + effect this improve the performance of "sort -M" by a factor of 4 + on my benchmarks. + +2004-11-03 Paul Eggert <eggert@cs.ucla.edu> + + * src/stty.c: Include "vasprintf.h" since we use vasprintf now. + + * src/Makefile.am (check-AUTHORS): Don't assume \? works in a sed + expression; it's not portable. Problem reported by Albert Chin. + Don't invoke a program more than once. + * src/groups.sh (version): New variable, containing author info, + for benefit of AUTHORS check. Use it when acting on --version option. + * AUTHORS: Remove duplicate lines. Remove bogus "chroot:" + in groups line. + + * src/system.h: Don't #define and #undef getopt around <stdlib.h>, + as this breaks the new regime that does "#define getopt rpl_getopt". + Problem reported by Albert Chin for Solaris 9 with Sun cc in: + http://lists.gnu.org/archive/html/bug-gnulib/2004-11/msg00019.html + I suppose this may cause problems on ancient hosts with + incompatible getopt declarations, but we'll cross that bridge if + the problem gets reported to us by someone who can test the fix. + +2004-11-03 Jim Meyering <jim@meyering.net> + + * src/tac.c: quote(...) file names in diagnostics. + +2004-10-29 Paul Eggert <eggert@cs.ucla.edu> + + * NEWS: Document getdate changes. + +2004-10-29 Jim Meyering <jim@meyering.net> + + * src/tac.c (tac_file): Remove temporary prototype and move this + function `down' so that it precedes definition of tac_nonseekable. + + `tac /proc/modules' would print nothing + Reported by Harald Dunkel in http://bugs.debian.org/278604. + + * src/tac.c (copy_to_temp): Renamed from save_stdin, since + now it copies a general file descriptor, not just stdin. + (tac_nonseekable): Renamed/adapted from tac_stdin. + (tac_file): Get fd via `open' directly rather than via fopen/fileno, + since we never used the stream. Perform "-" to stdin mapping here + rather than in main. Determine whether a file is seekable, + by trying to `lseek' to its end, and dispatch to tac_seekable or + tac_nonseekable accordingly. + (main): Rewrite argument handling now that it uses only tac_file. + * NEWS: Mention it here. + +2004-10-21 Jim Meyering <jim@meyering.net> + + * tests/mv/leak-fd: New file. + * tests/mv/Makefile.am (TESTS): Add it. + * tests/rm/dot-rel: New file. + * tests/rm/Makefile.am (TESTS): Add it. + + Correct my patch of 2004-10-18. + * src/remove.c (rm): Destroy the saved_cwd here (via cwd_state), + if necessary, not in remove_dir.
