4132561c17 touch: Handle nanosecond timestamps 2015-05-16 13:34:00 +01:00
Michael Forney
1d28fbd6cf mv, cp: Preserve nanosecond timestamps
Otherwise, we run into problems in a typical autoconf-based build
system:

  - config.status is created at some point between two seconds.
  - config.status is run, generating Makefile by first writing to a file
    in /tmp, and then mv-ing it to Makefile.
  - If this mv happens before the beginning of the next second, Makefile
    will be created with the same tv_sec as config.status, but with
    tv_nsec = 0.
  - When make runs, it sees that Makefile is older than config.status,
    and re-runs config.status to generate Makefile.

0545d32ce9 Handle '-' consistently
In general, POSIX does not define /dev/std{in, out, err} because it
does not want to depend on the dev-filesystem.
For utilities, it thus introduced the '-'-keyword to denote standard
input (and output in some cases) and the programs have to deal with
it accordingly.

Sadly, the design of many tools doesn't allow strict shell-redirections
and many scripts don't even use this feature when possible.

Thus, we made the decision to implement it consistently across all
tools where it makes sense (namely those which read files).

Along the way, I spotted some behavioural bugs in libutil/crypt.c and
others where it was forgotten to fshut the files after use.

347f0828f3 mktemp improvements
- add -p dir, -t and -u.
- fix dirname(tmp) check (did not check null terminator).

the semantics of mktemp is now the same as OpenBSD mktemp.

8f4b2e8689 ln: only check existence of src/to for hardlinks
This allows for creating dangling symlinks with force applied:

    # Before:
    $ ln -sf non-existant target
    ln: stat non-existent: No such file or directory
    $ ls -l target
    ls: lstat target: No such file or directory

    # After:
    $ ln -sf non-existant target
    $ ls -l target
    lrwxrwxrwx    1 eu    users   12 May 08 07:50 target -> non-existent

This also allows creating relative non-dangling symlinks with force applied:

    touch existant; mkdir dir

    # Before
    $ ln -sf ../existant dir
    ln: stat ../existant: No such file or directory
    $ ls -l dir

    # After
    $ ln -sf ../existant dir
    $ ls -l dir
    lrwxrwxrwx    1 eu    users   11 May 08 07:53 existant -> ../existant

The check for whether each src and to pairs are on the same device with the
same inode are only needed for hardlinks so that a forcefull link does
not remove the underlying file:

    touch f; mkdir dir

    # Before:
    $ ln -f f f dir
    ln: f and f are the same file
    $ ls -i f dir/f
    3670611 dir/f
    3670611 f

    # After:
    $ ln -f f f dir
    ln: f and f are the same file
    $ ls -i f dir/f
    4332236 dir/f
    4332236 f

b333176b8c Refactor and audit which(1)
Use the *at functions instead of building paths manually. We do
still have path-building in recurse() and other areas, but the
long-term goal is to rid most interfaces of that for practical
and security reasons.
In this case, it's more or less trivial.

Also, refactor the manpage to be more consistent with the others.

BUGFIX: Return exit status 3 on error.

5595af5742 Convert humansize() to accept a size_t instead of a double
General convention is to use size_t to store sizes of all kinds.
Internally, the function uses double anyway, but at least this
doesn't clobber up the API any more and there's a chance in the
future to make this function a bit cleaner and not use this dirty
static buffer hack any more.

9016d288f1 Do not use arg.h for tools which take no flags
We've already seen the issue with echo(1): Before we changed it to
ignore "--", the command

$ echo --

did not work as expected. Given POSIX mandated this and makes most
sense, in the interest of consistency the other tools need to be
streamlined for that as well.
Looking at yes(1) for instance, there's no reason to skip "--" in
the argument list.
We do not have long options like GNU does and there's no reason to
tinker with that here.

The majority of tools changed are ones taking lists of arguments
or only a single one. There's no reason why dirname should "fail"
on "--". In the end, this is a valid name.

The practice of hand-holding the user was established with the GNU
coreutils. "--help" and "--version" long-options are a disgrace to
what could've been done properly with manpages.
