+
+ Port to LFS and C9X in general, and to Solaris 2.6 in particular.
+
+ * NEWS: Describe ls -h, -H, rounding, new SI prefixes,
+ 64-bit accumulators, and LFS.
+
+ * acconfig.h (HAVE_INTTYPES_H, uintmax_t): New macros.
+
+ * configure.in (CPPFLAGS, LDFLAGS, LIBS): Set to appropriate
+ values if large file support needs explicit enabling.
+ (HAVE_INTTYPES_H, uintmax_t): New macros to configure.
+
+ * doc/fileutils.texi: Describe new -H option, new ls -h option.
+ Clarify about powers of 1000 vs 1024.
+
+ * lib/Makefile.am (libfu_a_SOURCES): Add new file human.c.
+ (noinst_HEADERS): Add new file human.h.
+
+ * lib/fileblocks.c (st_blocks): long -> off_t.
+ Avoid arithmetic overflow when size is near max.
+ Depend on _POSIX_SOURCE and BSIZE, not _POSIX_VERSION, for
+ compatibility with system.h.
+ (BSIZE): Remove definition, since if BSIZE is not defined
+ we're never invoked.
+
+ * lib/fsusage.c: Do all calculations using uintmax_t.
+ Include <inttypes.h> if available.
+ (adjust_blocks, CONVERT_BLOCKS): Remove.
+ (get_fs_usage): Set new member fsu_blocksize, and do not convert
+ numbers to 512-byte block units; this avoids overflow here.
+ Cast lseek arg to off_t, not long.
+
+ * lib/fsusage.h (struct fs_usage): New member fsu_blocksize.
+ Other members are now uintmax_t, not long.
+
+ * lib/human.c, lib/human.h: New files. The interface is inspired
+ by the human_readable function that was in du.c, but it's pretty
+ much rewritten from scratch.
+
+ * lib/idcache.c (getuidbyname, getgidbyname): Names can now
+ be NULL in cache. This change merely fixes ifdeffed-out code.
+
+ * lib/savedir.c (savedir): Check for size zero before invoking
+ malloc; this can occur if st_size arg overflows on conversion to
+ unsigned int. All callers now cast st_size arg to unsigned int.
+
+ * src/chgrp.c (<limits.h>, UINT_MAX, UINT_MAX): Remove; now
+ done by system.h.
+
+ * src/copy.c (copy_reg): Store file size as off_t, not long.
+ Do not assume st_size has been normalized to 512 byte blocks,
+ or that it fits in size_t after dividing by the blocksize.
+
+ * src/cp-hash.c (<inttypes.h>): Include if HAVE_INTTYPES_H.
+ (hash_insert2): Cast inode number to uintmax_t; this prevents
+ negative remainders if the inode number is negative and ino_t
+ is longer than unsigned.
+
+ * src/dd.c, src/df.c, src/du.c, src/ls.c (<inttypes.h>): Include if
+ HAVE_INTTYPES_H.
+ ("human.h"): Include.
+
+ * src/dd.c (input_blocksize, output_blocksize, conversion_blocksize):
+ Now size_t instead of long. 0 means unset.
+ (skip_records, seek_record, max_records): Now uintmax_t, not long.
+ (w_partial, w_full, r_partial, r_full, r_truncate):
+ Now uintmax_t instead of unsigned.
+ (print_stats): Print counts as uintmax_t, not unsigned.
+ (main, skip): Check for overflow when computing file offsets.
+ (skip): Records count arg is uintmax_t, not long; blocksize arg is
+ size_t, not long. Try lseek even on non regular files, as per comment.
+ (oc, col): Now size_t, not int.
+ (copy): No need to check max_records >= 0 any more, as the
+ default value is now effectively infinity.
+ Cast lseek arg to off_t.
+ (copy, copy_with_block): conversion_blocksize - col can never
+ be negative now, since it's unsigned, so rewrite loops to
+ avoid problems with unsigned.
+ (scanargs): Parse numeric args using uintmax_t, not int.
+ Check for overflow when converting block size args to size_t.
+ Blocksize options are now unsigned, and are now 0 when not set yet.
+ (parse_integer): Return uintmax_t, not int; accept new int * arg
+ to store error indicator, since all returned values are now valid.
+ Check for overflow when scanning integer.
+
+ * src/df.c (LONGEST_HUMAN_READABLE_1K_BYTE_BLOCKS): Remove.
+ (human_readable_base): Renamed from human_blocks; value is now
+ zero or positive integer, not just zero or nonzero.
+ (output_units): New variable;
+ replaces booleans kilobyte_blocks and megabyte_blocks.
+ (long_options): Add --si or -H.
+ (print_header): Adjust to renamed option variables.
+ (human_readable_1k_blocks): Remove.
+ (show_dev): Count blocks using uintmax_t, not long.
+ Calculate percentages using double, not long; this still isn't
+ perfect as it suffers double rounding, but it's more likely to
+ round correctly in practice than using long did.
+ Adjust to renamed option variables.
+ Use new human_readable library function to format uintmax_t values.
+ (usage): Add -H, --si.
+ (main): Adjust to renamed option variables.
+ Use -H if BLOCKSIZE is SI. Add -H.
+
+ * src/du.c (LONGEST_HUMAN_READABLE, enum Output_units): Remove.
+ (count_entry): Now returns uintmax_t, not long.
+ (human_readable_base): Renamed from opt_human_readable; value is now
+ zero or positive integer, not just zero or nonzero.
+ (output_units): Now an integer giving output size.
+ (tot_size): Now uintmax_t, not long.
+ (long_options, usage): Add --si or -H.
+ (main): Adjust to renamed option variables.
+ Use -H if BLOCKSIZE is SI. Add -H.
+ (human_readable): Remove; rewritten and now in lib/human.c.
+ (print_size): Rewrite in terms of human_readable.
+ Accept extra arg to be printed after size; all callers changed.
+
+ * src/install.c (BITSPERBYTE): Remove.
+ (UID_T_MAX, GID_T_MAX): Define in terms of TYPE_MAXIMUM.
+
+ * src/ls.c (<limits.h>): Don't include; system.h does it now.
+ (INT_MAX): Remove.
+ (longdiff): Remove bogus definition that uses subtraction;
+ it gives the wrong answer when overflows occur.
+ (convert_blocks): Remove.
+ (output_units): New variable;
+ replaces booleans kilobyte_blocks and megabyte_blocks.
+ (human_readable_base): New variable.
+ (long_options, usage): Add -h or --human-readable and -H or --si.
+ (decode_switches): Adjust to renamed option variables.
+ Use -H if BLOCKSIZE is SI. Add -h, -H.
+ (print_dir): Count blocks using uintmax_t, not int.
+ (gobble_file): Now returns uintmax_t, not int.
+ Don't convert blocks to 512 byte units, as this might overflow;
+ let caller handle the problem. Deduce what caller will print
+ by invoking human_readable.
+ (print_long_format, print_file_name_and_frills): Don't assume
+ inode number, block count, file size fit in unsigned long.
+ Use human_readable to do block count conversion and to print
+ file sizes.
+ (prep_non_filename_text): Print decimal string for time if
+ localtime fails due to enormous time_t.
+
+ * src/system.h (<limits.h>): Include if HAVE_LIMITS_H.
+ (CHAR_BIT, TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM, INT_MAX, UINT_MAX):
+ New macros.
+ (ST_NBLOCKS): Now counts actual blocks, not 512-byte blocks.
+ (ST_NBLOCKSIZE): New macro.
+

* src/sys2.h: New file -- but just temporary.
