Following examples show the cases.
% ktrace -f - false >/dev/null && echo wrong
wrong
% ktrace -f - -i /usr/sbin/update >/dev/null
(does not return to command line)
That is, back out last change and restore the roles of parent/child for
ktrace(1). The ktruss(1) stuff still remains.
Yes, ktruss(1) has the problems. Better implementation is expected.
- add `usage'; displays the usage of a command.
implemented by calling the c_handler() with argc = 0, argv = "funcname".
- add `passive auto'; does the same as $FTPMODE=auto.
- add `set [option value]'; display all options, or set an option to a value.
- add `unset option'; unset an option.
- add getoptionvalue() to retrieve an option's value, and replace a few
global variables with calls to this.
- implement cleanuppeer(), which resets various bits of state back to
`disconnected'. call in disconnect() and lostpeer().
- support completing on `options'.
- improve recovery after a SIGINT may have closed the connection.
XXX: there's still a couple to fix
other stuff:
- various consistency fixes in the man page.
- ensure that the command usage strings in the code and man page match reality.
- mput/mget: check that the connection still exists before each xfer.
- minor cosmetic changes in confirm().
- set code correctly in sizecmd() and modtime()
- don't need \n in err() strings.
- change lostpeer to take an argument (rather than casting (sig_t)lostpeer
in signal handlers)
- knf and whitespace police.
only return a header length of 0 if we are using -f (force), not
in the case when we know how long the header is. this stops from
playing the audio header.
* simplify main loop (don't need `top' variable any more)
* use a struct sockaddr_in6.sin6_addr for the result from inet_pton(),
rather than u_char buf[16]
* add a few more comments
* confirm(): move from util.c to cmds.c. display mnemonic string in its prompt.
add support for `q' (terminate current xfer), `?' (show help list)
* in various signal handlers, output a linefeed only if fromatty.
* if fgets(stdin) returned NULL (i.e, EOF), clearerr(stdin) because you don't
want future fgets to fail. this is not done for the fgets() in the main
command loop, since ftp will quit at that point.
* unless ftp is invoked with -a, don't retain the anonftp setting between
hosts (`ftp somehost:' sets anonftp, but you don't want that to `stick'
if you close that connection and open a new one).
stage. if this occurs, just call lostpeer() to close the connection. whilst this
might be considered brutal, it's also extremely handy if you're impatient or there's
lossage at the remote end.
don't save the signal mask on some foreign systems.
* ensure signal handlers don't use stdio and do reset errno if they
don't exit with siglongjmp()
* use a common SIGINT handler for {send,recv}request()
(work around editline's override)
* minor cleanup of signal handler (along the lines of similar work in
recvrequest()). the handlers should now be reset everytime the cleanup
handler was callled.
prints out info if bytes > 0). only set the handler if SIGINFO is defined
* hijack SIGQUIT to be the same as SIGINFO (foreign ports have this, and it's
annoying to have SIGQUIT dump core on netbsd when it prints info on other
systems)
* in {recv,send}request(), factor a lot of duplicated code out into a
`cleanup' section at the end
* rework shell() a bit
* implement xsignal_restart(), which only sets the SA_RESTART flag if
specifically requested
* xsignal() is now a wrapper to xsignal_restart(). INFO, USR1, USR2 and WINCH
are restartable, ALRM, INT, PIPE and QUIT are not.
* improve getreply()'s timeout code to take advantage of the above.
other changes:
* improve wording of how globbing works for `classic' URLs (host:path).
suggested by John Refling <johnr@imageworks.com> in relation to PRs
[bin/8519] and [bin/8520]
* always compile in the `edit' command even if NO_EDITCOMPLETE defined.
it's just a no-op in the latter case, which is more consistent to
the users.
* always compile in about: support (i.e, remove NO_ABOUT).
i'm entitled to some vanity in this program...
* clean up some whitespace
the disabled state can be overridden by toggling epsv4.
(I got sick of the errors about EPSV not being supported on almost
every server I connect to. This way we retain support for epsv4, but
it's not so whiny after the first failure...)
to "extern" if it's not set. define GLOBAL to (empty) in main.c.
this effectively moves all the globals into main.c whilst retaining
namespace access to them in other source files.
(global vars in header files confuse foreign linkers)
should be in host order. found/fixed by Matthias Pfaller <leo@dachau.marco.de>
* parse_url(): improve checking of portnum, and add an extra argument to pass
back the parsed portnum to the caller (reduces a bit of code duplication)
* Move the KAME/WIDE copyrights after the BSD/TNFi ones. Since there was
significantly less code added under the former, it's only fair on the latter.
