fd8f6d2269 Don't close a FILE * which we know is bogus. 2003-08-29 15:54:12 +00:00

39082bb4a5 Some servers respond to RETR in active mode with 125 (connection already 
open) rather than 150 (opening connection).  There's no reason why we
shouldn't accept that.

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.

9601e333a8 Wrap everything in struct connection, and enforce timeouts everywhere 
(except for DNS operations).  Always use funopen() for HTTP, to support

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.

6c81eb523e Somewhere along the line, I misunderstood the whole FTP_PASSIVE_MODE debate 
and had libfetch selecting passive mode even when FTP_PASSIVE_MODE was not
set at all, which is really quite surprising unless you know about it. So
change it to the agreed default behaviour of selecting passive mode if
FTP_PASSIVE_MODE is set, but not "no".

c7d40ef296 Use funopen() instead of fdopen(). This fixes three problems: 
- ftpTimeout was not honored when reading actual data, as opposed to
   talking protocol

 - connection caching was broken because _ftp_cached_connect() would see
   the result of the transfer instead of the result of the NOOP.

 - if the RETR succeeded, but an error occurred later (as can happen
   when talking to a proxy), the error would not be detected.

There still remains to register an atexit(3) callback to close the cached
connection gracefully instead of just dropping it on the floor.

0f27c7838c Don't fail if _ftp_stat() reports a protocol error, since that most likely

hard failure.
