2010-05-11sendrecv: make them two pairs of send/recv to properly deal with FTPSHoward Chu
FTP(S) use two connections that can be set to different recv and send functions independently, so by introducing recv+send pairs in the same manner we already have sockets/connections we can work with FTPS fine. This commit fixes the FTPS regression introduced in change d64bd82.
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.
2010-04-16GnuTLS: make the connection phase non-blockingJerome Vouillon
When multi interface is used, the SSL handshake is no longer blocking when GnuTLS is used.
2010-04-16SSL_RECV: EOF is not an error hereDaniel Stenberg
The recent overhaul of the SSL recv function made this treat a zero returned from gnutls_record_recv() as an error, and this caused our HTTPS test cases to fail. We leave it to upper layer code to detect if an EOF is a problem or not.

2009-08-01- Curt Bogmine reported a problem with SNI enabled on a particular server. WeDaniel Stenberg
should introduce an option to disable SNI, but as we're in feature freeze now I've addressed the obvious bug here (pointed out by Peter Sylvester): we shouldn't try to enable SNI when SSLv2 or SSLv3 is explicitly selected. Code for OpenSSL and GnuTLS was fixed. NSS doesn't seem to have a particular option for SNI, or are we simply not using it?
2009-07-22- David Binderman found a memory and fd leak in lib/gtls.c:load_file()Michal Marek
(https://bugzilla.novell.com/523919). When looking at the code, I found that also the ptr pointer can leak.
2009-05-05I simplified the SSL session id re-use code now to *always* ditch the previousDaniel Stenberg
one and store the current one, as it makes the code less complex and I'm not even sure I can check for the same session id using memcmp() like that.
2009-05-04- Inspired by Michael Smith's session id fix for OpenSSL, I did theDaniel Stenberg
corresponding fix in the GnuTLS code: make sure to store the new session id in case the re-used one is rejected.
2009-04-21libcurl's memory.h renamed to curl_memory.hYang Tse
2009-03-08- Andre Guibert de Bruet fixed the gnutls-using code: There are a few placesDaniel Stenberg
in the gnutls code where we were checking for negative values for errors, when the man pages state that GNUTLS_E_SUCCESS is returned on success and other values indicate error conditions.
2009-02-25- As Daniel Fandrich figured out, we must do the GnuTLS initing in theDaniel Stenberg
curl_global_init() function to properly maintain the performing functions thread-safe. We've previously (28 April 2007) moved the init to a later time just to avoid it to fail very early when libgcrypt dislikes the situation, but that move was bad and the fix should rather be in libgcrypt or elsewhere.

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!
2008-10-16Renamed Curl_ascii_equal to Curl_raw_equal and bugfixed the my_toupper functionDaniel Stenberg
used in strequal.c so now all test cases run fine for me again.
2008-10-15- Pascal Terjan filed bug #2154627Daniel Stenberg
(http://curl.haxx.se/bug/view.cgi?id=2154627) which pointed out that libcurl uses strcasecmp() in multiple places where it causes failures when the Turkish locale is used. This is because 'i' and 'I' isn't the same letter so strcasecmp() on those letters are different in Turkish than in English (or just about all other languages). I thus introduced a totally new internal function in libcurl (called Curl_ascii_equal) for doing case insentive comparisons for english-(ascii?) style strings that thus will make "file" and "FILE" match even if the Turkish locale is selected.

2008-06-06- Axel Tillequin and Arnaud Ebalard added support for CURLOPT_ISSUERCERT, forDaniel Stenberg
OpenSSL, NSS and GnuTLS-built libcurls.

2008-02-26Added support for server name indication (RFC 4366).Gunter Knauf
Patch submitted by Kaspar Brand.
2008-02-25- Kaspar Brand made GnuTLS-built libcurl properly acknowledge the option thatDaniel Stenberg
forces it to prefer SSLv3.
2008-02-20oops, fixed to buildDaniel Stenberg
2008-02-20- Based on initial work done by Gautam Kachroo to address a bug, we now keepDaniel Stenberg
better control at the exact state of the connection's SSL status so that we know exactly when it has completed the SSL negotiation or not so that there won't be accidental re-uses of connections that are wrongly believed to be in SSL-completed-negotiate state.
2008-02-20- We no longer support setting the CURLOPT_URL option from inside a callbackDaniel Stenberg
such as the CURLOPT_SSL_CTX_FUNCTION one treat that as if it was a Location: 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.
2008-02-16oops, that was debug code not meant to be committed like this...Daniel Stenberg
2008-02-16fix warnings about shadowingDaniel Stenberg
2008-02-15- Made the gnutls code path not even try to get the server cert if no peerDaniel Stenberg
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
2008-02-08- Mike Hommey filed and fixed bug report #1889856Daniel Stenberg
(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.
2008-02-07- Refactored a lot of timeout code into a few functions in an attempt to makeDaniel Stenberg
them all use the same (hopefully correct) logic to make it less error-prone and easier to introduce library-wide where it should be used.
2007-11-07if () => if()Daniel Stenberg
while () => while() and some other minor re-indentings
2007-10-03I renamed the CURLE_SSL_PEER_CERTIFICATE error code toDaniel Stenberg
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.
2007-08-30Renamed several libcurl error codes and options to make them more generalDan Fandrich
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)
2007-08-24Remove leading space in curl_version_info ss_version field.Patrick Monnerat
2007-08-01Patrick Monnerat and I modified libcurl so that now it *copies* all stringsDaniel Stenberg
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.
2007-07-29Bug report #1759542 (http://curl.haxx.se/bug/view.cgi?id=1759542). A bad useDaniel Stenberg
of a socket after it has been closed, when the FTP-SSL data connection is taken down.
2007-07-20Made some const arrays static to avoid unnecessary stack usage.Dan Fandrich
2007-07-107.16.4 prepsDaniel Stenberg
2007-04-28Peter O'Gorman fixed libcurl to not init GnuTLS as early as we did before,Daniel Stenberg
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.
2007-04-21Daniel Black filed bug #1704675 (http://curl.haxx.se/bug/view.cgi?id=1704675)Daniel Stenberg
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.
