fd5847ef09 828. [bug] The errno value from recvfrom() could be overwritten 
by logging code. [RT #1293]

5e194abb5b 814. [bug] Socket objects left over from accept() failures 
were incorrectly destroyed, causing corruption
                        of socket manager data structures.

 813.   [bug]           File descriptors exceeding FD_SETSIZE were handled
                        badly. [RT #1192]

7900390a52 Previous change turned invalid peer address returns from accept() 
into hard errors - they should be soft errors

a84cfaa3f2 The bug fix in socket.c 1.189 was less than ideal: if a socket 
got wedged in a state where accept() always returns EBADF, the server would loop calling
internal_accept() repeatedly.  Implemented an alternative fix where a hard
error in accept() causes an event with a nonzero result code to be sent, and
the new socket object to be freed

2eb3dafdcf Add the socket flag ISC_R_NORETRY, which makes the socket code treat 
a soft error as a hard error on send (that is, not retry it).  It also
modifies the code calling sendmsg() to retry on EINTR.

c05eeed3c9 754. [bug] Certain failure returns from sendto() could 
cause the server to retry the transmission
                        indefinitely. [RT #902]

1f7f8d5c07 Add isc_socket_sendto2() and isc_socket_recv2(). These versions take 
a partially constructed event and flags.  The flags can include
ISC_SOCKFLAG_IMMEDIATE, which means that if the operation completes, the
event is filled in and not sent.

df0bcff664 extend change #727 to check returned address length for zero. 2001-02-07 23:40:28 +00:00
Andreas Gustafsson
9a3ee1570d "hard" errors in accept() were handled really badly. They were logged 
twice, and the socket object for the new socket was never destroyed,
causing the server to hang on exit (if multithreaded) or dump core on exit
(if singlethreaded).  Now the only difference between "hard" and "soft" errors
is that the latter are not logged.

8dab78b566 as a workaround for various OS bugs, do not INSIST() that 
accept() returns a valid peer address; instead just log an ugly error message
and continue if the peer address is left unchanged or insane by accept()

dfb0717d75 - Receive and send operations on UDP sockets no longer need to acquire 
the socket lock.  (Assuming the operation succeeds immediately, and doesn't
need to be queued.)

- Communications with the watcher thread tweaked to reduce the need for
locking.

801dceea23 Revert my last change. It was stupid, which I if I had been thinking clearly 
I would have seen *before* I commited anything.  So, include isc/thread.h,
isc/mutex.h and isc/condition.h even if ISC_PLATFORM_USETHREADS is not defined.

(What caused me to bother with this at all was a problem that I resolved
a few days ago by fixing configure ... though now that I think about it,
that probably means there is some other latent problem with inconsistent
definitions that could maybe be handled better.  I'll look into it more
later, AFTER vacation.)

isc_msgcat_get() and speed things up.
