Jake Burkholder 7b628f43e0 Reduce WARNS level to 3 in the non-crypto case to fix make release on sparc64. 
This may only be turning up now to changes in the cpp predefines for sparc64,
which may be turning on more strict alignment checking.

Dag-Erling Smørgrav 1a5424b137 Slight amendment to rev 1.34: instead of considering any short read an 
error, only report an error if no data was read at all (unless len was
0 to start with).  Otherwise, the final read of practically any transfer
will end in a fatal error.

Dag-Erling Smørgrav 2761348f78 Introduce _fetch_writev(), which is the conn_t version of writev(2). In 
the SSL case, it is no different from the old _fetch_write(), but in the
non-SSL case it uses writev(2) to send the entire vector as a single
packet (provided it can fit in one packet).  Implement _fetch_write()
and _fetch_putln() in terms of _fetch_writev().

This should improve performance in the non-SSL case (by reducing protocol
overhead) and solve the problem where too-smart-for-their-own-good
firewalls reject FTP packets that do not end in CRLF.

Dag-Erling Smørgrav e24f60e74f Back out the previous commit, and fix the bug rather than try to hide its 
symptoms: make timeouts and short transfers fatal, and set errno to an
appropriate value (ETIMEDOUT for a timeout, EPIPE for a short transfer).

Nate Lawson 13cc1c8394 The FTP connection caching needs a better interface -- connections are 
closed through _fetch_close() which is the only one who knows the connection
REALLY was closed (since ref -> 0).  However, FTP keeps its own local
cached_connection and checks if it is valid by comparing it to NULL.  This
is bogus since it may have been freed elsewhere by _fetch_close().

This change checks if we are closing the cached_connection and the ref is 1
(soon to be 0).  If so, set cached_connection to NULL so we don't
accidentally reuse it.  The REAL fix should be to move connection caching
to the common.c level (_fetch_* functions) and NULL the cache(s) in
_fetch_close().  Then all layers could benefit from caching.

Tim J. Robbins 9d649c1fd0 When recycling a cached connection, increment the reference count so that 
the heap block does not get freed and reused. This should fix the
pkg_add -r crashes that have been happening for months.

Dag-Erling Smørgrav 3f4823c55d Fix a bug I introduced in the chunk decoder in the previous commit.. 2002-06-05 10:23:19 +00:00
Dag-Erling Smørgrav dea29ca1d5 First step towards SSL support: wrap connections in a 'struct connection' 
which contains the socket descriptor, the input buffer and (yet unused)
SSL state variables.  This has the neat side effect of greatly improving
reentrance (though we're not *quite* there yet) and opening the door to
HTTP connection caching.

This commit is inspired by email conversations with and patches from
Henry Whincup <henry@techiebod.com> last fall.

Mark Murray 4cd0119367 Do not use __progname directly (except in [gs]etprogname(3)). 
Also, make an internal _getprogname() that is used only inside
libc. For libc, getprogname(3) is a weak symbol in case a
function of the same name is defined in userland.
