to what the manpage and POSIX say) copied as symlinks, even without -R.
Return ENOENT instead. Closes PR 6975 by Johan Danielsson <joda@pdc.kth.se>.
From FreeBSD: return correct error message if source directory is
unreadable; remove unnecessarily included headers.
string legally (it strdup()s the argument). How pax-as-tar `-o' ever
worked without a coredump is beyond me...
Also modify pax-as-tar `-o' to do three things, which depend on the
create/extract mode:
- write V7 format archives (which, though part of GNU tar, actually
goes along with the following point--after all, old pax-as-tar created
V7 archives by default);
- write archives with "write_opt=nodir", as pax already did, and as
specified by 4.2BSD;
- extract archives with owner/group set to invoking user, as specified
by SUS.
even if the specified file is not in the PATH.
This change enforces security and makes it conform to POSIX.
Closes PR #6794.
I thought Christos committed this but not appeared yet. :)
The setstackmark()/popstackmark() pair in dotcmd(), used for freeing
stack storage possibly allocated by find_dot_file(), is redundant for now
since dotcmd() is surrounded by another pair in evalcommand().
This redundancy, however, may help future modifications
(suggested by Christos).
The problem was that system calls got restarted after a signal,
instead of returning EINTR. Thus the read builtin, had no way to
know that a signal occured that could change the course of execution.
Since the code has sprinkled checks for EINTR all over the place,
it is supposed to work properly with non restartable syscalls.
The fix is to use siginterrupt(signo, 1), before setting a signal
handler, to make sure that system calls don't get restarted.
Rewrite man page in mandoc format rather than nasty man format.
Fix a ton of parsing errors, and generate proper .Xr's.
document all known environment variables.
suggest ksh rather than bash.
The last two fix PR #1966. Wheee!
Somebody with access to the POSIX spec needs to go in here, and document
our adherence, or lack thereof.
