1f3345b9e6 Staticise some symbols in tr(1) 2015-01-10 14:26:32 +00:00

a582cb8a2f Rewrite tr(1) in a sane way
tr(1) always used to be a saddening part of sbase, which was
inherently broken and crufted.
But to be fair, the POSIX-standard doesn't make it very simple.
Given the current version was unfixable and broken by design, I
sat down and rewrote tr(1) very close to the concept of set theory
and the POSIX-standard with a few exceptions:

 - UTF-8: not allowed in POSIX, but in my opinion a must. This
          finally allows you to work with UTF-8 streams without
          problems or unexpected behaviour.
 - Equivalence classes: Left out, even GNU coreutils ignore them
                        and depending on LC_COLLATE, which sucks.
 - Character classes: No experiments or environment-variable-trickery.
                      Just plain definitions derived from the POSIX-
                      standard, working as expected.

I tested this thoroughly, but expect problems to show up in some
way given the wide range of input this program has to handle.
The only thing left on the TODO is to add support for literal
expressions ('\n', '\t', '\001', ...) and probably rethinking
the way [_*n] is unnecessarily restricted to string2.

The list is getting too long.  Leave the maintainers at the top
and add a section of authors/contributors below the license statement.

bb59d2eb34 ls: No need to set errno to zero
Consider the following code:

pw = getpwuid(uid);
if (!pw) {
	if (errno)
		...
	else
		...
}

If the entry was not found then as per POSIX errno is not set
because that is not considered to be a failing condition.  errno
is only set if an internal error occurred.

If errno happened to be non-zero before the getpwuid() call
because of a previous error then we'll report a bogus error.

In this case, we have to set errno to zero before the call to
getpwuid().

However in ls(1) we only really care if the password entry was found
and we do not report any errors so setting errno to 0 is not necessary.

0d7822f866 Don't free the line buffer for each file
There's no point free-ing memory when the kernel can do it for us.
Just reuse the already allocated memory to hold lines.

Thanks Truls Becken for pointing this out.

e14e0becce cp: Rename -d option to -P
The -d option is a GNU extension and is equivalent to its "-P
--preserve=links" options.

Since we don't implement the --preserve=links functionality anyway (it
means preserve hard links between files), just call it -P, which is
specified by POSIX.

Additionally, there is no need to check for cp_Pflag again before
copying the symlink itself because the only way the mode in the stat
will indicate a symlink is if we used lstat (which we only do if -P is
specified).

757cf0651a Fix basename suffix treatment
Explicitly use "." instead of the result of basename(3) when argv[0] is
an empty string in order to avoid a segfault.

Skip suffix treatment if the result of basename(3) is "/", per POSIX.

Fix the suffix check, which was previously checking for a match at any
location in the string.
