When we move the exit() out of venprintf(), we can reuse it for
weprintf(), which basically had duplicate code.
I also renamed venprintf() to xvprintf (extended vprintf) so it's
more obvious what it actually does.
getrhs() must remove \ excepts in the case of & and \d
(where d is a digit), because in this case are sequences
understood by addsub(), so addsub() must be able to see
them.
The majority of the systems define PRIO_MAX and PRIO_MIN,
but there is an obscure system, whose name I am not going
to tell, where they were not defined.
Every system is going to have a different configuration
so the only solution is to put an ifdef guard for every
value. To do this, we generate the header at compile time
with a shell script.
When a error occurs it is important to remove all the modifications
done by the offending command and restore the value of dot to the
state before of executing the command.
by re-ordering when chmod/chown is done, only a list of directories (not
all files) need be kept for fixing mtime.
this also fixes an issue where set-user-id files in a tar may not work. chmod
is done before chown and before the file is written. if ownership changes, or
the file is being written as a normal user, the setuid bit would be cleared.
also fixes ownership of symbolic links. previously a chown() was called,
which would change the ownership of the link target. lchown() is now
used for symbolic links.
renamed all ent, ent* functions to dir* as it better describes what they
do.
use timespec/utimensat instead of timeval/utimes to get AT_SYMLINK_NOFOLLOW
This reverts commit a564a67c4ea70e90a4dc543814458e4903869d3e.
Not as trivial as I thought. This breaks cp when used as:
cp -r /foo/bar /baz
The old code expands this to:
cp -r /foo/bar /baz/bar
This can happen if you move a file from one filesystem to another.
rename(2) will fail and we will fall through to a manual cp + rm.
Initiate the rm through recurse() like we do for rm(1).
Thanks to Heiko for reporting this.
POSIX says
Copying shall begin at the point in the file indicated by the -c
number or -n number options.
The origin for counting shall be 1; that is, -c +1 represents the
first byte of the file, -c -1 the last.
The origin for counting shall be 1; that is, -n +1 represents the
first line of the file, -n -1 the last.
ls was using (old) UNIX spec (struct stat).st_[acm]time.
It now uses POSIX (struct stat).(struct timespec st_[acm]tim) which
gives time resolution in seconds and nanoseconds.
If two files have the same time in seconds, we extend the comparision to
nanoseconds.
