2011-04-05return code cleanup: build, init and run-time errorsDaniel Stenberg
Stop the abuse of CURLE_FAILED_INIT as return code for things not being init related by introducing two new return codes: CURLE_NOT_BUILT_IN and CURLE_UNKNOWN_OPTION CURLE_NOT_BUILT_IN replaces return code 4 that has been obsoleted for several years. It is used for returning error when something is attempted to be used but the feature/option was not enabled or explictitly disabled at build-time. Getting this error mostly means that libcurl needs to be rebuilt. CURLE_FAILED_INIT is now saved and used strictly for init failures. Getting this problem means something went seriously wrong, like a resource shortage or similar. CURLE_UNKNOWN_OPTION is the option formerly known as CURLE_UNKNOWN_TELNET_OPTION (and the old name is still present, separately defined to be removed in a very distant future). This error code is meant to be used to return when an option is given to libcurl that isn't known. This problem would mostly indicate a problem in the program that uses libcurl.
2011-03-14sslgen: define Curl_ssl_connect_nonblocking for non-SSLDaniel Stenberg
The non-blocking connect improvement for IMAP showed that we didn't properly define the Curl_ssl_connect_nonblocking function for non-SSL builds. Reported by: Tor Arntsen
2010-05-07sendrecv: split the I/O handling into private handlerHoward Chu
Howard Chu brought the bulk work of this patch that properly moves out the sending and recving of data to the parts of the code that are properly responsible for the various ways of doing so. Daniel Stenberg assisted with polishing a few bits and fixed some minor flaws in the original patch. Another upside of this patch is that we now abuse CURLcodes less with the "magic" -1 return codes and instead use CURLE_AGAIN more consistently.

2009-05-04- Michael Smith posted bug report #2786255Daniel Stenberg
(http://curl.haxx.se/bug/view.cgi?id=2786255) with a patch, identifying how libcurl did not deal with SSL session ids properly if the server rejected a re-use of one. Starting now, it will forget the rejected one and remember the new. This change was for OpenSSL only, it is likely that other SSL lib code needs similar fixes.
2008-11-11- Rainer Canavan filed bug #2255627Daniel Stenberg
(http://curl.haxx.se/bug/view.cgi?id=2255627) which pointed out that a program using libcurl's multi interface to download a HTTPS page with a libcurl built powered by OpenSSL, would easily get silly and instead hand over SSL details as data instead of the actual HTTP headers and body. This happened because libcurl would consider the connection handshake done too early. This problem was introduced at September 22nd 2008 with my fix of the bug #2107377 The correct fix is now instead done within the GnuTLS-handling code, as both the OpenSSL and the NSS code already deal with this situation in similar fashion. I added test case 560 in an attempt to verify this fix, but unfortunately it didn't trigger it even before this fix!

2008-09-05- Introducing CURLOPT_CERTINFO and the corresponding CURLINFO_CERTINFO. ByDaniel Stenberg
enabling this feature with CURLOPT_CERTINFO for a request using SSL (HTTPS or FTPS), libcurl will gather lots of server certificate info and that info can then get extracted by a client after the request has completed with curl_easy_getinfo()'s CURLINFO_CERTINFO option. Linus Nielsen Feltzing helped me test and smoothen out this feature. Unfortunately, this feature currently only works with libcurl built to use OpenSSL. This feature was sponsored by networking4all.com - thanks!
2008-07-05fix compiler warning: empty body in an if-statementYang Tse
2008-06-11- I did a cleanup of the internal generic SSL layer and how the various SSLDaniel Stenberg
libraries are supported. Starting now, each underlying SSL library support code does a set of defines for the 16 functions the generic layer (sslgen.c) uses (all these new function defines use the prefix "curlssl_"). This greatly simplified the generic layer in readability by involving much less #ifdefs and other preprocessor stuff and should make it easier for people to make libcurl work with new SSL libraries. Hopefully I can later on document these 16 functions somewhat as well. I also made most of the internal SSL-dependent functions (using Curl_ssl_ prefix) #defined to nothing when no SSL support is requested - previously they would unnecessarily call mostly empty functions.

2007-01-05- Linus Nielsen Feltzing introduced the --ftp-ssl-ccc command line option toDaniel Stenberg
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.
2006-11-11cleaned up Curl_write() and the sub functions it uses for various protocols.Daniel Stenberg
They all now return ssize_t to Curl_write(). Unfortunately, Curl_read() is in a sorrier state but it too would benefit from a similar cleanup.

2006-05-10David McCreedy provided a fix for CURLINFO_LASTSOCKET that does extendedDaniel Stenberg
checks on the to-be-returned socket to make sure it truly seems to be alive and well. For SSL connection it (only) uses OpenSSL functions.
2006-03-21Xavier Bouchoux made the SSL connection non-blocking for the multi interfaceDaniel Stenberg
(when using OpenSSL).
2005-04-07GnuTLS support added. There's now a "generic" SSL layer that we use all overDaniel Stenberg
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
