32a4a82829 Fix an off-by-one error (> where >= should have been used) which caused 
_fetch_writev() to incorrectly report EPIPE in certain cases.

Also fix a number of const warnings by using __DECONST(), plus a signed /
unsigned comparison by casting the rhs to ssize_t.

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.

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.

9f788e9c90 Eliminate two cases of undefined behaviour: total in _fetch_write() was 
not initialized before use, and _http_growbuf() did not return a value
on success.

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).

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.

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.

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.

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.
