FRIGN 7d2683ddf2 Sort includes and more cleanup and fixes in util/ 2014-11-14 10:54:10 +00:00
Evan Gates 0810c61154 add -D_DEFAULT_SOURCE to placate gcc 2014-11-14 10:37:52 +00:00
sin ee55fbe9e9 Just make $(HDR) a prereq for $(OBJ) 
The result is always correct but it might do redundant builds.
Not really an issue as sbase builds very fast.  The alternative is
to track the header deps manually but this is already incomplete and
unlikely to be kept up to date.

FRIGN eee98ed3a4 Fix coding style 
It was about damn time. Consistency is very important in such a
big codebase.

sin e35d9e62a5 Just use HOST_NAME_MAX in hostname(1) 
Using sysconf() + malloc() is overkill.

We should investigate the current state of the tools one by one
and mark out those that are complete and POSIX conformant.

sin 5773a8f22b Implement concat() using read(2) and write(2) 
This forces the data to be read as soon as they are available
and a simple cat(1) when stdin is referring to a tty works as
expected.

Michael Forney 6164445cce Fix symbolic mode parsing in parsemode 
I found quite a lot of bugs, so I ended up pretty much rewriting as I
followed the spec¹.

Now, it works as follows:

- Determine a mask (who) of bits that can be modified for the subsequent
  operations. If none are specified, select all file mode bits.
- In a loop, determine which operation (+, -, =) to apply.
- If the next character is a permcopy (u, g, o), set the new permissions
  (perm) corresponding to the bits set in the user, group or other parts
  of the existing mode.
- Otherwise, set the new permissions by looping through the next r, w,
  x, s, t characters.
- Now, the set of bits we want to add or remove is (who & perm). Set or
  remove these bits according the the operation (first clearing the
  appropriate bits if the operation is =).
- Continue from the top if the next character is a comma, otherwise,
  process the next operation.

I tested this on some made up inputs, and I believe it is working
correctly now:

  parsemode("g+w", 0644, 0),    before: 0606, now: 0664, fixed
  parsemode("u+rx", 0222, 0),   before: 0077, now: 0722, fixed
  parsemode("+x", 0644, 023),   before: 0754, now: 0754, still works
  parsemode("+w", 0444, 022),   before: 0644, now: 0644, still works
  parsemode("+w", 0444, 0),     before: 0666, now: 0666, still works
  parsemode("+s", 0755, 0),     before: 0755, now: 6755, fixed
  parsemode("u+s", 0755, 0),    before: 0055, now: 4755, fixed
  parsemode("g+s", 0755, 0),    before: 0705, now: 2755, fixed
  parsemode("g=u", 0700, 0),    before: 0000, now: 0770, fixed
  parsemode("go=u-w", 0700, 0), before: 0000, now: 0755, fixed
  parsemode("o+u-g", 0641, 0),  before: 0000, now: 0643, fixed
  parsemode("u=rx,o+w,g-r", 0654, 0) before: error, now: 0516, fixed
  parsemode(",", 0654, 0), before: error, now: error, still works

Michael Forney 6327290cf2 grep: Fix -c flag 2014-11-02 09:46:52 +00:00
Michael Forney 1ca8a314f8 grep: Remove newlines before matching a line 
Otherwise, a pattern with a '$' anchor will never match and POSIX says that

  "By default, an input line shall be selected if any pattern ... matches any
   part of the line excluding the terminating <newline>"

Michael Forney 0e8a8c9426 tar: Support typeflag '\0' when extracting 
POSIX recommends that "For backwards-compatibility, a typeflag value of
binary zero ( '\0' ) should be recognized as meaning a regular file when
extracting files from the archive".
