sin eca23e5308 tail: Add -num to usage and fix manpage to align with head.1 2015-03-05 08:16:58 +00:00
Hiltjo Posthuma 31f0624f3d code-style: minor cleanup and nitpicking 2015-02-20 13:29:38 +01:00
FRIGN 31572c8b0e Clean up #includes 2015-02-14 21:12:23 +01:00
FRIGN 7c578bf5b0 Scrap writerune(), introducing fputrune()
Interface and function as proposed by cls.
Code is also shorter, everything else analogous to fgetrune().

FRIGN a5ae899a48 Scrap readrune(), introducing fgetrune()
Interface as proposed by cls, but internally rewritten after a few
considerations.
The code is much shorter and to the point, aligning itself with other
standard functions. It should also be much faster, which is not bad.

sin 989127e525 tail: Skip leading spaces in tail -n " +20" 2015-02-09 16:10:00 +00:00
sin fe3fc41838 tail: Fix tail -n -val to handle leading spaces
Previously 'tail -n "    -20" foo' was broken, now it works.

sin 124cb7415a tail: Ignore anything other than FIFOs and regular files for -f 2015-02-09 15:03:35 +00:00
sin a25a57f6ac tail: Add rudimentary support to detect file truncation
We cannot in general detect that truncation happened.  At the moment
we use a heuristic to compare the file size before and after a write
happened.  If the new file size is smaller than the old, we correctly
handle truncation and dump the entire file to stdout.

If it so happened that the new size is larger or equal to the old size
after the file had been truncated without any reads in between, we will
assume the data was appended to the file.

There is no known way around this other than using inotify or kevent
which is outside the scope of sbase.

sin 080a1ee833 No need to free the buffer for every call to getline()
It will realloc as necessary if the new line size exceeds the
capacity of the allocated buffer.

Enough with this insanity!

There are more instances of this problem.

FRIGN e17b9cdd0a Convert codebase to use emalloc.c utility-functions
This also definitely increases readability and makes OOM-conditions
more consistent.

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

Hiltjo Posthuma fab4b384e7 use agetline instead of agets
also use agetline where fgets with a static buffer was used previously.

sin b8edf3b4ee Add weprintf() and replace fprintf(stderr, ...) calls
There is still some programs left to be updated for this.

Many of these programs would stop on the first file that they
could not open.

This is useful to support the obsolete syntax -NUM for tools like
head, tail and fold.

Fixed for consistency purposes.

sin 7d4d519a51 Fix segfault in tail(1)
We should not be looking at optarg, that's uninitialized.  We
are not using getopt.
