* src/checkpoint.c: Include <flexmember.h>.
(struct checkpoint_action): New member commandbuf.
(checkpoint_action_tail): Now pointer to pointer,
to simplify updating. All uses changed.
(alloc_action): New arg quoted_string, to lessen number of
separate allocations. All uses changed.
* src/checkpoint.c (copy_string_unquote, getarg)
(format_checkpoint_string): Prefer idx_t to size_t.
(copy_string_unquote): Simplify by using ximemdup0.
(getarg): Avoid quadratic reallocation behavior by
using xpalloc.
* src/buffer.c (flush_write_ptr, flush_bufmap, bufmap_locate):
(struct zip_magic, available_space_after, _flush_write)
(short_read, flush_archive, try_new_volume)
(gnu_add_multi_volume_header, simple_flush_read)
(simple_flush_write, _gnu_flush_read, _gnu_flush_write)
(gnu_flush_write): Prefer idx_t to size_t when either will do, as
signed types are typically safer. For a tiny value in memory,
just use ‘char’.
* src/buffer.c (start_offset): New variable.
(get_archive_status): If reading from seekable stdin, store the
position in the stream corresponding to record_start in start_offset.
(seek_archive): Compute current offset relative to start_offset.
This fixes an extra argument left over in a function call by commit
0dfcfa4aa4. Reported by Matteo Croce.
* src/buffer.c (_open_archive): Fix extra argument to paxfatal.
* src/extract.c (ALL_MODE_BITS, RECOVER_NO, RECOVER_OK)
(RECOVER_SKIP): Now constants or inline functions, not macros.
(maybe_recoverable): Return enum recover, not int.
* src/create.c (CACHEDIR_SIGNATURE, CACHEDIR_SIGNATURE_SIZE)
(MAX_VAL_WITH_DIGITS, MAX_OCTAL_VAL): Now constants or
inline functions or removed, instead of macros.
(max_octal_val): Accept size rather than type.
In common.h, replace macros with constants or functions when that
is easy. This makes code a bit more reliable (functions evaluate
their args exactly once) and easier to debug (many debugging
environments cannot access macros).
* src/common.h (CHKBLANKS): Remove. All uses removed.
(NAME_FIELD_SIZE, PREFIX_FIELD_SIZE, UNAME_FIELD_SIZE)
(GNAME_FIELD_SIZE, TAREXIT_SUCCESS, TAREXIT_DIFFERS)
(TAREXIT_FAILURE, LG_8, LG_256, DEFAULT_CHECKPOINT)
(MAX_OLD_FILES, TF_READ, TF_WRITE, TF_DELETED, XFORM_REGFILE)
(XFORM_LINK, XFORM_SYMLINK, XFORM_ALL, WARN_ALONE_ZERO_BLOCK)
(WARN_BAD_DUMPDIR, WARN_CACHEDIR, WARN_CONTIGUOUS_CAST)
(WARN_FILE_CHANGED, WARN_FILE_IGNORED, WARN_FILE_REMOVED)
(WARN_FILE_SHRANK, WARN_FILE_UNCHANGED, WARN_FILENAME_WITH_NULS)
(WARN_IGNORE_ARCHIVE, WARN_IGNORE_NEWER, WARN_NEW_DIRECTORY)
(WARN_RENAME_DIRECTORY, WARN_SYMLINK_CAST, WARN_TIMESTAMP)
(WARN_UNKNOWN_CAST, WARN_UNKNOWN_KEYWORD, WARN_XDEV)
(WARN_DECOMPRESS_PROGRAM, WARN_EXISTING_FILE, WARN_XATTR_WRITE)
(WARN_RECORD_SIZE, WARN_FAILED_READ, WARN_MISSING_ZERO_BLOCKS)
(WARN_VERBOSE_WARNINGS, WARN_ALL, EXCL_DEFAULT, EXCL_RECURSIVE)
(EXCL_NON_RECURSIVE): Now enum constants rather than macros.
(time_option_initialized, isfound, wasfound, warning_enabled):
Now functions rather than macros TIME_OPTION_INITIALIZED, ISFOUND,
WASFOUND, WARNING_ENABLED. All uses changed.
(OLDER_STAT_TIME, OLDER_TAR_STAT_TIME, EXTRACT_OVER_PIPE)
(TAR_ARGS_INITIALIZER): Remove. All uses replaced with their
definiens or equivalent.
* src/sparse.c (struct ok_n_block_ptr): New type.
(decode_num): Revamp API so that it does the work of both
the old decode_num and the old COPY_BUF. Always read to the
next newline even if there is a lot of junk in between.
(pax_decode_header): Use the new API.
(COPY_BUF): Remove.
* src/sparse.c (struct block_ptr):
New type, to allow a functional style.
(dump_str_nl, floorlog10): New static functions.
(COPY_STRING): Remove. All uses replaced by dump_str_nl.
(pax_dump_header_1): Use floorlog10 instead of creating a string.
Simplify size calculation.
Simplify the code by assuming C99 initializers.
* src/list.c (base_64_digits): Remove.
(base64_map): Now a constant. Now has its (old value + 1) % 65,
as that’s the only easy portable way to do it with a static
initializer (even on platforms where CHAR_BIT != 8); all uses changed.
(base64_init): Remove; only use removed.
(from_header): Adjust to new values in base64_map.
* src/list.c (base_64_digits): Remove; no longer needed.
(base64_map): Now const, initialized statically, and with
invalid entries being 0 not 64, and with valid entries
being 1 greater than before.
* src/tar.c (assert_format, decode_options):
Prefer signed to unsigned integers.
(optloc_save): Prefer enum to unsigned integer.
Simplify allocation.
(decode_options): No need to call ngettext for a value known
to be plenty large.
This works better on platforms where SIZE_MAX < OFF_MAX.
* src/common.h (struct common locus):
* src/names.c (struct name_elt):
Use intmax_t for line numbers. All uses changed.
