(hard_LC_COLLATE): Define even if ! ENABLE_NLS.
(main): Always initialize hard_LC_COLLATE.
Put initialization next to other locale-related stuff.
Include <langinfo.h> even if ! ENABLE_NLS.
(decimal_point, th_sep): Depend on HAVE_SETLOCALE, not ENABLE_NLS.
(main): Likewise.
(MONTHTAB_CONST): Remove; all uses removed.
(struct_month_cmp, inittables): Do not depend on ENABLE_NLS.
(main): hard_LC_TIME locale does not depend on ENABLE_NLS.
|
|
(usage): Document only the intersection of the old and new behaviors,
to encourage portability.
(short_options): Remove; no longer needed.
(COMMON_SHORT_OPTIONS): New macro.
(main): Parse options using POSIX 1003.1-2001 rules if
conforming to that standard. Do not warn of obsolete options.
|
|
support of obsolete "-N" option syntax in expand, head, fold,
split, tail, unexpand, uniq, and which prohibits options with
optional arguments in od and pr.
(main): Check for obsolete options.
(short_options): New constant.
|
|
Use xmemcoll instead of memcoll.
(die): Do not invoke cleanup; atexit does this now.
(main): Use atexit to invoke cleanup on exit.
Set xmemcoll_exit_failure to SORT_FAILURE.
|
|
between two size_t values can be stored in an int; this doesn't
work, for example, on 64-bit Solaris.
|
|
|
|
|
|
support of obsolete "+" option syntax in sort, tail, and uniq.
(usage, main): Implement this.
|
|
|
|
now preferred, as it connotes 1024) as well as 'k'.
|
|
HELP_OPTION_DESCRIPTION and VERSION_OPTION_DESCRIPTION.
|
|
instead of hard-coding --help and --version descriptions.
|
|
Split usage strings so that --help and --version descriptions are alone
in their own string.
Likewise for the one that says:
Mandatory arguments to long options are mandatory for short options too.
|
|
|
|
cpp directive that guards the use.
|
|
Use fputs, not printf.
|
|
That can cause problems (now documented in coreutils.texi).
|
|
``Mandatory arguments to long options are mandatory for short options too.\n\''
|
|
Instead, allocate at least sort_size bytes total.
|
|
`and'.
|
|
|
|
|
|
`multi-character' rather than `multibyte' in a diagnostic.
|
|
code, since RLIMIT_RSS is similar (and is not standardized).
(default_sort_size): Don't allocate more than the RSS limit,
if this host has such a limit.
|
|
(usage, main): Add support for long options, and check option
syntax as POSIX requires, though (as usual for GNU apps)
options can follow file names unless POSIXLY_CORRECT is set.
Many diagnostic revamped.
(long_options): New constant.
(badfieldspec): New arg MSGID. Mark as noreturn.
(parse_field_count): New arg MSGID; if null, just return null on error.
(new_key): Renamed from key_init. All callers changed. Now allocates
the new key.
|

|
better. All callers changed.
|
|
(sort_size): Now the user-specified sort size.
(MIN_MERGE_BUFFER_SIZE): New macro.
(MIN_SORT_SIZE): Use it.
(merge_buffer_size): New variable.
(fillbuf): Increase merge_buffer_size if a longer line is encountered.
(checkfp, mergefps): Do not allocate a buffer smaller than
merge_buffer_size.
(sort): Use the default_sort_size if sort_size is zero.
(main): Do not set sort_size to default_sort_size.
|
|
|
|
the inner scope where they're used.
(sort): Likewise.
|
|
(xfopen): Use stdout if *how != 'r'.
(mergefps): Remove FPS arg.
Open all input files, and close all files when done.
If OFP is null, open the output file (but after opening input files).
All callers changed.
(first_same_file): New function.
(sort, merge): Remove arg OFP; we now open the output file as needed.
All callers changed.
(merge): New arg MAX_MERGE. All callers changed.
(sort): For "sort F -o F", close the input before opening the output.
(main): Do not use close_stdout; 'sort' and 'merge' now close stdout.
(This also fixes a close-stdout-twice bug.)
Remove test for overlapping input and output files, as 'sort' no longer
needs to worry about overlap, and 'merge' checks for overlap itself.
Use first_same_file to inform 'merge' about how much to merge at
the top level, to avoid overlap.
|
|
(create_temp_file, xfopen, xfclose, write_bytes, sort_buffer_size,
fillbuf, main): Use it to regularize error messages. The only change
in behavior is that write_bytes and the final close used to say "write
error" but now give just the output file name, which should be enough.
|
|
on error. All callers changed.
|
|
the output file in the error message; mention "-" instead.
|
|
Use fopen_safer, not fopen, to avoid subtle bugs when fopen returns
stdin, stdout, or stderr.
(xfclose): stdout is no longer a special case.
(main): Close output file, don't just flush it; there might be
an error on the close.
|
|
allocated, repeatedly halve it until allocation succeeds.
|
|
|
|
representing temp files. This improved CPU performance of
'sort -S 1 *.[ch]' by 17% on my host.
(struct tempnode): name member now uses struct hack.
(temphead): Now a pointer, not a structure. All uses changed.
(create_temp_file): Allocate node using struct hack.
(zaptemp): Free node using struct hack. Use pointer comparison, not
string comparison.

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.
|
|
into the inner scope where they are used.
|
|
|
|
(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.

(SORTALLOC, mergealloc, LINEALLOC): Remove.
(sortalloc): Default to zero at program startup.
(SORTALLOC_MIN, SORTALLOC_DEFAULT_MIN): New macros.
(usage, main): Add support for new -S SIZE option.
(specify_sort_size, default_sort_size): New functions.
(initlines): Do not let alloc exceed limit.
(findlines): Likewise.
(checkfp, mergefps, sort): Use sortalloc to size everything
else, instead of relying on precomputed sizes.
