following. The patch that introduced this feature was done for 7.11.0, but
this code and functionality has been broken since about 7.15.4 (March 2006)
with the introduction of non-blocking OpenSSL "connects".
It was a hack to begin with and since it doesn't work and hasn't worked
correctly for a long time and nobody has even noticed, I consider it a very
suitable subject for plain removal. And so it was done.
verification is requested. Previously it would even return failure if gnutls
failed to get the server cert even though no verification was asked for.
- Fix my Curl_timeleft() leftover mistake in the gnutls code
(http://curl.haxx.se/bug/view.cgi?id=1889856): When using the gnutls ssl
layer, cleaning-up and reinitializing curl ends up with https requests
failing with "ASN1 parser: Element was not found" errors. Obviously a
regression added in 7.16.3.
CURLE_PEER_FAILED_VERIFICATION (standard CURL_NO_OLDIES style), and made this
return code get used by the previous SSH MD5 fingerprint check in case it
fails.
and allow reuse by multiple protocols. Several unused error codes were
removed. In all cases, macros were added to preserve source (and binary)
compatibility with the old names. These macros are subject to removal at
a future date, but probably not before 2009. An application can be
tested to see if it is using any obsolete code by compiling it with the
CURL_NO_OLDIES macro defined.
Documented some newer error codes in libcurl-error(3)
passed to it with curl_easy_setopt()! Previously it has always just refered
to the data, forcing the user to keep the data around until libcurl is done
with it. That is now history and libcurl will instead clone the given
strings and keep private copies.
since it then inits libgcrypt and libgcrypt is being evil and EXITS the
application if it fails to get a fine random seed. That's really not a nice
thing to do by a library.
identifying a double-free problem in the SSL-dealing layer, telling GnuTLS to
free NULL credentials on closedown after a failure and a bad #ifdef for NSS
when closing down SSL.
and CURLOPT_CONNECTTIMEOUT_MS that, as their names should hint, do the
timeouts with millisecond resolution instead. The only restriction to that
is the alarm() (sometimes) used to abort name resolves as that uses full
seconds. I fixed the FTP response timeout part of the patch.
Internally we now count and keep the timeouts in milliseconds but it also
means we multiply set timeouts with 1000. The effect of this is that no
timeout can be set to more than 2^31 milliseconds (on 32 bit systems), which
equals 24.86 days. We probably couldn't before either since the code did
*1000 on the timeout values on several places already.
curl that uses the new CURLOPT_FTP_SSL_CCC option in libcurl. If enabled, it
will make libcurl shutdown SSL/TLS after the authentication is done on a
FTP-SSL operation.
(http://curl.haxx.se/bug/view.cgi?id=1480821) He found and identified a
problem with how libcurl dealt with GnuTLS and a case where gnutls returned
GNUTLS_E_AGAIN indicating it would block. It would then return an unexpected
return code, making Curl_ssl_send() confuse the upper layer - causing random
28 bytes trash data to get inserted in the transfered stream.
The proper fix was to make the Curl_gtls_send() function return the proper
return codes that the callers would expect. The Curl_ossl_send() function
already did this.
#1334338 (http://curl.haxx.se/bug/view.cgi?id=1334338). When reading an SSL
stream from a server and the server requests a "rehandshake", the current
code simply returns this as an error. I have no good way to test this, but
I've added a crude attempt of dealing with this situation slightly better -
it makes a blocking handshake if this happens. Done like this because fixing
this the "proper" way (that would handshake asynchronously) will require
quite some work and I really need a good way to test this to do such a
change.
(missing file, bad file, etc), gnutls will no longer handshake properly but it
just loops forever. Therefore, we must return error if we get an error when
setting the CA cert file name. This is not the same behaviour as with OpenSSL.

internally, with code provided by sslgen.c. All SSL-layer-specific code is
then written in ssluse.c (for OpenSSL) and gtls.c (for GnuTLS).
As far as possible, internals should not need to know what SSL layer that is
in use. Building with GnuTLS currently makes two test cases fail.
TODO.gnutls contains a few known outstanding issues for the GnuTLS support.
GnuTLS support is enabled with configure --with-gnutls
