(long_options): Use it instead of 'H' for --si.
(decode_switches): Warn that -H will change soon.
(usage): Likewise.

|
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.
|
|
|
|
(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.

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.

(wc): Rename local `wc' to avoid shadowing function name.
|
|
(remove_file): Revert last change.
|
|
|
|
Remove workaround macros for hosts that have mbrtowc but not
mbstate_t, as we now insist on proper declarations for both
before using mbrtowc.

(wheel_tab): New global table.
(WHEEL_START, WHEEL_END): Define.
(factor): Remove the loop that special-cased `2'.
Instead of incrementing by `2', use the offsets from the wheel table.

Use UINT_MAX_32_BITS in the cpp conditions that determine
the `word32' typedef. Using a literal `0xffffffff' failed with
HPUX10.20's /bin/cc.

don't remove the symlink. Reported by David Luyer as Debian bug#82089,
via Michael Stone.

Set *copy_into_self in the new code that detects that.
Make diagnostic more consistent: s/won't/will not/.
[move_mode, copy_into_self]: Give a diagnstic here, now that
we have the top_level_* globals. Remove the corresponding diagnostic
from mv.c.
Add a FIXME comment.

Set `fail' to nonzero in the primary `if (copy_into_self)' block
rather than in its own tiny one below.

now that we've overloaded it a little, in order to detect and diagnose
the copying-directory-into-self problem.
(new_file): Remove global.
(htab): Declare global to be static.
(remember_created): Insert file name instead of dummy pointer, so
that copy.c can use the just-created directory name to detect
the copying-directory-into-self problem.
