(OPEN_NO_FOLLOW_SYMLINK): Remove definition. Use O_NOFOLLOW in
place of all uses, since it is guaranteed (system.h) to be defined.
|

Remove umask_kill, don't change the process umask, and let the kernel
apply the umask where appropriate.
(make_dir_parents_private): Fix logic for POSIX ACLs.
|
|
On systems with an ACL library, arrange
to link with it via $(LIB_ACL), for the utilities that need it.
|
|
(copy_reg, copy_internal): Use copy_acl and set_acl
instead of fchown/chown. Fix the logic for POSIX ACLs.
(chown_succeded): Remove; we now always copy acls and
preserve S_ISUID, S_ISGID, and S_ISVTX when needed, no matter if we
did a chown before or not.
|
|
is no requirement for ACL support; particularly, it does not exist
on systems that have POSIX ACLs.
|
|
(OPENAT_CWD_RESTORE__ALLOW_FAILURE): Likewise.
(fd_to_subdirp): Remove openat_cwd_restore_allow_failure arg; its
value is now signified by whether cwd_errno is null.
(fd_to_subdirp, remove_dir, rm_1); Change cwd failure indicator from
pointer-to-bool to pointer-to-errno-value. All callers changed.
(rm_1): Don't bother setting a local cwd failure flag and then
ORing it into the caller's. Just set the caller's.
(rm): Use cwd failure errno value to print a slightly-better
diagnostic.

end of a --printf format string. Reported by Paul Eggert.
|
|
|
|
add new option: --printf=FMT
(isodigit, octtobin, hextobin): Define.
(PRINTF_OPTION): Define.
(interpret_backslash_escapes, trailing_delim): New globals.
(usage): Document them. Alphabetize on long option names.
(print_esc_char): New function.
(print_it): Rewrite, in order to handle backslash escapes.
(main): Handle new option. Set globals for --format, too.
|
|
(check_ordering_compatibility, main): Use it.
(main): Check for -c and -o.
Don't bother with a usage message for
"sort -c a b", for consistency with other error diagnostics.
|
|
(main): Use it.

Don't include md5.h; it wasn't needed.
(struct keyfield): Rename random_hash to random, for consistency
with the other member names. All uses changed.
(usage): Tweak wording to mention STRING for --seed option.
(short_options): Rorder for consistency with other programs.
(rand_state): Now a struct, not a pointer to one. All uses changed.
(HASH_WORDS, HASH_SIZE): Remove.
(get_hash): Remove comments around resbuf size, since we can assume C89.
Use a "more-kosher" (but slower) approach of invoking isaac_refill.
(keycompare): Adjust to the new get_hash.
Add a FIXME.
(badfieldspec): Omit recently-introduced comment; it isn't needed.
(main): Don't set need_random simply because gkey has it set; that
doesn't necessarily mean we'll need random numbers.
Redo seeding to match new get_hash approach.
|
|
(fillrand, dopass, main): Undo previous change.

changing it to allow for varying numbers of words in the state.
Alter so that we include rand-isaac.c directly rather than
compiling it and linking to it. Don't include config.h or
system.h; that's the includer's responsibility.
(ISAAC_LOG, ISAAC_WORDS, ISAAC_BYTES, struct isaac_state, ind):
(isaac_step, struct irand_state):
Resurrect these, with the same defns that used to be in shred.c.
(ISAAC_SIZE, isaac_new, isaac_copy): Remove.
(isaac_refill, isaac_seed_start, isaac_seed_data, irand_init, irand32):
static again.
(struct isaac_state, isaac_refill, isaac_mix, isaac_init):
(isaac_seed_start, isaac_seed_data, isaac_seed_finish, isaac_seed):
(irand_init, irand32, irand_mod):
Number of words is constant again.

Make the local an `int' instead.
|
|
(isaac_refill): Don't try to negate a
local of type uint32_t. Convert it to int32_t first.
|
|
|
|
Mark all other functions as `extern' so the tight-scope
part of `make distcheck' passes once again.
* src/rand-isaac.h (isaac_mix): Remove declaration.
|
|
(main): Split a long line so it fits in 80 columns.
|
|
|
|
causing `make distcheck' to fail.
|
|
(usage): Add options --random-sort and --seed to implement a random
shuffle.
Include md5.h and rand-isaac.h.
(get_hash): New function.
(rand_state): New var.
(HASH_WORDS, HASH_SIZE): New macros.
|
|
(fillrand, main): Adjust to the fact that the state size is now
runtime-configurable.
|
|
(shred_SOURCES, sort_SOURCES): New macros, so we compile rand-isaac.c.
|
|
Make state size runtime-configurable.
(isaac_new, isaac_copy): New functions.

|
(set_owner, preserve_author): New functions, factored out of copy_reg.
(copy_reg): Use them.
(copy_internal): Use them here, too.

testing-only option to start with `-', so that it cannot render
ambiguous any prefix it happens to share with some other option name.

(usage): -a includes dummy file systems, not size-0 file systems.

to avoid collision with POSIX name space. All uses changed.
