2011-12-02multi interface: only use non-NULL function pointer!Daniel Stenberg
If the socket callback function pointer hasn't been set, we must not attempt to use it. Commit adc88ca20 made it more likely to occur.
2011-12-02multi: handle timeouts on DNS servers by checking for new socketsJason Glasgow
If the first name server is not available, the multi interface does not invoke the socket_cb when the DNS request to the first name server timesout. Ensure that the list of sockets are always updated after calling Curl_resolver_is_resolved. This bug can be reproduced if Curl is complied with --enable_ares and your code uses the multi socket interfaces and the CURLMOPT_SOCKETFUNCTION option. To test try: iptables -I INPUT \ -s $(sed -n -e '/name/{s/.* //p;q}' /etc/resolv.conf)/32 \ -j REJECT and then run a program which uses the multi-interface.
2011-12-01POP3: fixed escaped dot not being striped outSteve Holme
Changed the eob detection to work across the whole of the buffer so that lines that begin with a dot (which the server will have escaped) are passed to the client application correctly.

2011-11-29POP3: detect when LIST returns no mailsDaniel Stenberg
By making sure the function can detect an "end of body" sequence immediately on the first line, test 811 is now enabled.
2011-11-29POP3: fix end of body detectionDaniel Stenberg
Curl_pop3_write() now has a state machine that scans for the end of a POP3 body so that the CR LF '.' CR LF sequence can come in everything from one up to five subsequent packets. Test case 810 is modified to use SLOWDOWN which makes the server pause between each single byte and thus makes the POP3 body get sent to curl basically one byte at a time.

2011-11-25SSLSESSION_SHARED: new macro to check if session is sharedDaniel Stenberg
Added convenience macro to use to check if a handle is using a shared SSL session, and fixed so that Curl_ssl_close_all() doesn't lock when the session isn't shared.

2011-11-25tvdiff_secs(): sub-zero time difference adjustmentYang Tse
Skip a floating point addition operation when integral part of time difference is zero. This avoids potential floating point addition rounding problems while preserving decimal part value.
2011-11-25telnet: fix macros to allow proper semicolon useDaniel Stenberg
Macros that look like function calls need to be made so that we can use semicolons properly for indentation and for reducing the risk for mistakes when using them.
2011-11-25TELNET: improved treatment of optionsLaurent Rabret
1) enables the Window Size option 2) allows the server to enable the echo mode 3) allows an app using libcurl to disable the default binary mode Signed-off-by: Laurent Rabret
2011-11-24query-part: ignore the URI part for given protocolsJonas Schnelli
By setting PROTOPT_NOURLQUERY in the protocol handler struct, the protocol will get the "query part" of the URL cut off before the data is handled by the protocol-specific code. This makes libcurl adhere to RFC3986 section 2.2. Test 1220 is added to verify a file:// URL with query-part.

2011-11-23gnutls: only translate winsock errors for old versionsMark Brand
Bugfix: https handshake fails using gnutls 3 on windows http://sourceforge.net/tracker/index.php?func=detail&aid=3441084&group_id=976&atid=100976 New gnutls versions have an error handler that knows about Winsock errors, which is why gnutls_transport_set_global_errno() was deprecated and then removed. This is a correction of commit f5bb370 (blame me) which meant to reimplement gnutls_transport_set_global_errno(), which is not necessary.
2011-11-21protocol_connect: show verbose connect and set connect timeDaniel Stenberg
Regression: commit b998d95b (shipped first in release 7.22.0) made the condition always equal false that should reset the TIMER_CONNECT timer and call the Curl_verboseconnect() function. Reported by: "Captain Basil" Bug: http://curl.haxx.se/mail/archive-2011-11/0035.html

2011-11-06ftp PORT: don't hang if bind() failsDaniel Stenberg
When the user requests PORT with a specific port or port range, the code could lock up in an endless loop. There's now an extra conditional that makes sure to special treat the error and try the local address only once so a second failure will abort the loop correctly.

2011-11-06pingpong: change two comments wrongly referring "FTP"Daniel Stenberg
Just a sign of where the code originally was ripped out from. Now it is generic "pingpong".
2011-11-06HTTP auth: fix proxy Negotiate bugRene Bernhardt
If a proxy offers several Authentication schemes where NTLM and Negotiate are offered by the proxy and you tell libcurl not to use the Negotiate scheme then the request never returns when the proxy answers with its HTTP 407 reply. It is reproducible by the following steps: - Use a proxy that offers NTLM and Negotiate ( CURLOPT_PROXY and CURLOPT_PROXYPORT ) - Tell libcurl NOT to use Negotiate CURL_EASY_SETOPT(CURLOPT_PROXYAUTH, CURLAUTH_BASIC | CURLAUTH_DIGEST | CURLAUTH_NTLM ) - Start the request The call to CURL_EASY_PERFORM never returns. If you switch on debug logging you can see that libcurl issues a new request As soon as it received the 407 reply. Instead it should return and set the response code to 407. Bug: http://curl.haxx.se/mail/lib-2011-10/0323.html
2011-11-04ssluse.c: fix calling of OpenSSL's ERR_remove_state(0)Yang Tse
Move calling of ERR_remove_state(0) a.k.a ERR_remove_thread_state(NULL) from Curl_ossl_close_all() to Curl_ossl_cleanup(). In this way ERR_remove_state(0) is now only called in libcurl by curl_global_cleanup(). Previously it would get called by functions curl_easy_cleanup(), curl_multi_cleanup and potentially each time a connection was removed from a connection cache leading to premature destruction of OpenSSL's thread local state hash. Multi-threaded apps using OpenSSL enabled libcurl should still call function ERR_remove_state(0) or ERR_remove_thread_state(NULL) at the very end end of threads that do not call curl_global_cleanup().
2011-11-03url.c and file.c: fix OOM triggered segfaultYang Tse
2011-11-03rename ftp_ssl: the struct field is used for many protocolsDaniel Stenberg
Now called 'use_ssl' instead, which better matches the current CURLOPT name and since the option is used for all pingpong protocols (at least) it makes sense to not use 'ftp' in the name.
2011-11-02gtls_connect_step1: remove use of deprecated functionsDaniel Stenberg
Use gnutls_priority_set_direct() instead of gnutls_protocol_set_priority(). Remove the gnutls_certificate_type_set_priority() use since x509 is the default certificate type anyway. Reported by: Vincent Torri

2011-10-27multi: start ftp state machine when switching to DO_MOREDaniel Stenberg
This extends the fix from commit d7934b8bd491 When the multi state is changed within the multi_runsingle from DOING to DO_MORE, we didn't immediately start the FTP state machine again. That then left the FTP state in FTP_STOP. When curl_multi_fdset() was subsequently called, the ftp_domore_getsock() function would return the wrong fd info. Reported by: Gokhan Sengun
2011-10-24ftp.c: some OOM handling fixesYang Tse
2011-10-21curl_multi_fdset: correct fdset with FTP PORT useDaniel Stenberg
After a PORT has been issued, and the multi handle would switch to the CURLM_STATE_DO_MORE state (which is unique for FTP), libcurl would return the wrong fdset to wait for when curl_multi_fdset() is called. The code would blindly assume that it was waiting for a connect of the second connection, while that isn't true immediately after the PORT command. Also, the function multi.c:domore_getsock() was highly FTP-centric and therefore ugly to keep in protocol-agnostic code. I solved this problem by introducing a new function pointer in the Curl_handler struct called domore_getsock() which is only called during the DOMORE state for protocols that set that pointer. The new ftp.c:ftp_domore_getsock() function now returns fdset info about the control connection's command/response handling while such a state is in use, and goes over to waiting for a writable second connection first once the commands are done. The original problem could be seen by running test 525 and checking the time stamps in the FTP server log. I can verify that this fix at least fixes this problem.

2011-10-20Curl_smtp_escape_eob: first byte is index 0...Daniel Stenberg
Fix a bug with with commit 2621dd42a4d that happened due to my last second pre-commit cleanup of the change without proper testing afterwards!
2011-10-20gtls: only call gnutls_transport_set_lowat with <gnutls-2.12.0Tim Harder
The default lowat level for gnutls-2.12* is set to zero to avoid unnecessary system calls and the gnutls_transport_set_lowat function has been totally removed in >=gnutls-3 which causes build failures. Therefore, the function shouldn't be used except for versions that require it, <gnutls-2.12.0.
2011-10-20Curl_smtp_escape_eob: fix EOB escapingDaniel Stenberg
As the EOB string can come byte by byte over a series of writes we must match byte-wise. Bug: http://curl.haxx.se/mail/lib-2011-10/0172.html
2011-10-17singleipconnect: unstick the ipv6-connection booleanDaniel Stenberg
Previously the bit was set before the connection was found working so if it would first fail to an ipv6 address and then connect fine to a IPv4 address the variable would still be TRUE. Reported by: Thomas L. Shinnick Bug: http://curl.haxx.se/bug/view.cgi?id=3421912
