2011-03-25fix: re-use of bound connectionsDaniel Stenberg
When asked to bind the local end of a connection when doing a request, the code will now disqualify other existing connections from re-use even if they are connected to the correct remote host. This will also affect which connections that can be used for pipelining, so that only connections that aren't bound or bound to the same device/port you're asking for will be considered.
2011-03-14protocols: use CURLPROTO_ internallyDaniel Stenberg
The PROT_* set of internal defines for the protocols is no longer used. We now use the same bits internally as we have defined in the public header using the CURLPROTO_ prefix. This is for simplicity and because the PROT_* prefix was already used duplicated internally for a set of KRB4 values. The PROTOPT_* defines were moved up to just below the struct definition within which they are used.
2011-03-14protocol handler: added flags fieldDaniel Stenberg
The protocol handler struct got a 'flags' field for special information and characteristics of the given protocol. This now enables us to move away central protocol information such as CLOSEACTION and DUALCHANNEL from single defines in a central place, out to each protocol's definition. It also made us stop abusing the protocol field for other info than the protocol, and we could start cleaning up other protocol-specific things by adding flags bits to set in the handler struct. The "protocol" field connectdata struct was removed as well and the code now refers directly to the conn->handler->protocol field instead. To make things work properly, the code now always store a conn->given pointer that points out the original handler struct so that the code can learn details from the original protocol even if conn->handler is modified along the way - for example when switching to go over a HTTP proxy.
2011-03-13SSH: add protocol lock directionDaniel Stenberg
Some protocols have to call the underlying functions without regard to what exact state the socket signals. For example even if the socket says "readable", the send function might need to be called while uploading, or vice versa. This is the case for libssh2 based protocols: SCP and SFTP and we now introduce a define to set those protocols and we make the multi interface code aware of this concept. This is another fix to make test 582 run properly.
2011-03-12PROT_CLOSEACTION: added SFTP and SCPDaniel Stenberg
Both SFTP and SCP are protocols that need to shut down stuff properly when the connection is about to get torned down. The primary effect of not doing this shows up as memory leaks (when using SCP or SFTP with the multi interface). This is one of the problems detected by test 582.

2010-12-23multi: connect fail => use next IP addressDaniel Stenberg
When using the multi interface and connecting to a host name that resolves to multiple IP addresses, there was no logic that made it continue to the next IP if connecting to the first address times out. This is now corrected.
2010-12-18ares: ask for both IPv4 and IPv6 addressesTommie Gannert
Make the c-ares resolver code ask for both IPv4 and IPv6 addresses when IPv6 is enabled. This is a workaround for the missing ares_getaddrinfo() and is a lot easier to implement. Note that as long as c-ares returns IPv4 addresses when IPv6 addresses were requested but missing, this will cause a host's IPv4 addresses to occur twice in the DNS cache.

2010-12-15urldate: undef hideous memory definesDaniel Stenberg
The public axTLS header (at least as of 1.2.7) redefines the memory functions. We #undef those again immediately after the public header to limit the damage. This should be fixed in axTLS.
2010-12-15Preparing for axTLS. Actual SSL API functions are only stubbed.Eric Hu
Added axTLS to autotool files and glue code to misc other files. axtls.h maps SSL API functions, but may change. axtls.c is just a stub file and will definitely change.
2010-12-06url: provide dead_connection flag in Curl_handler::disconnectKamil Dudka
It helps to prevent a hangup with some FTP servers in case idle session timeout has exceeded. But it may be useful also for other protocols that send any quit message on disconnect. Currently used by FTP, POP3, IMAP and SMTP.

2010-11-13urldata: Capitalize enum protect_level values.Julien Chaffraix
This makes it easier to spot the enum values from the variables. Removed some unneeded DEBUGASSERT added in the previous commit.
2010-11-13security: tighten enum protection_level usage.Julien Chaffraix
While changing Curl_sec_read_msg to accept an enum protection_level instead of an int, I went ahead and fixed the usage of the associated fields. Some code was assuming that prot_clear == 0. Fixed those to use the proper value. Added assertions prior to any code that would set the protection level.
2010-11-11ip_version: moved to connection structDaniel Stenberg
The IP version choice was previously only in the UserDefined struct within the SessionHandle, but since we sometimes alter that option during a request we need to have it on a per-connection basis. I also moved more "init conn" code into the allocate_conn() function which is designed for that purpose more or less.
2010-11-08CURLOPT_RESOLVE: addedDaniel Stenberg
CURLOPT_RESOLVE is a new option that sends along a curl_slist with name:port:address sets that will populate the DNS cache with entries so that request can be "fooled" to use another host than what otherwise would've been used. Previously we've encouraged the use of Host: for that when dealing with HTTP, but this new feature has the added bonus that it allows the name from the URL to be used for TLS SNI and server certificate name checks as well. This is a first change. Surely more will follow to make it decent.
2010-11-05Revert: use Host: name for SNI and cert name checksDaniel Stenberg
This reverts commit b0fd03f5b8d4520dd232a9d13567d16bd0ad8951, 4b2fbe1e97891f, afecd1aa13b4f, 68cde058f66b3
2010-11-04host: get the custom Host: name more genericlyDaniel Stenberg
When given a custom host name in a Host: header, we can use it for several different purposes other than just cookies, so we rename it and use it for SSL SNI etc.

2010-08-25http: handle trailer headers in all chunked responsesDaniel Stenberg
HTTP allows that a server sends trailing headers after all the chunks have been sent WITHOUT signalling their presence in the first response headers. The "Trailer:" header is only a SHOULD there and as we need to handle the situation even without that header I made libcurl ignore Trailer: completely. Test case 1116 was added to verify this and to make sure we handle more than one trailer header properly. Reported by: Patrick McManus Bug: http://curl.haxx.se/bug/view.cgi?id=3052450
2010-08-15multi: support timeoutsDaniel Stenberg
Curl_expire() is now expanded to hold a list of timeouts for each easy handle. Only the closest in time will be the one used as the primary timeout for the handle and will be used for the splay tree (which sorts and lists all handles within the multi handle). When the main timeout has triggered/expired, the next timeout in time that is kept in the list will be moved to the main timeout position and used as the key to splay with. This way, all timeouts that are set with Curl_expire() internally will end up as a proper timeout. Previously any Curl_expire() that set a _later_ timeout than what was already set was just silently ignored and thus missed. Setting Curl_expire() with timeout 0 (zero) will cancel all previously added timeouts. Corrects known bug #62.
2010-08-10parse_remote_port: fix ;type= URL suffix over HTTP proxyDaniel Stenberg
Test 563 is enabled now and verifies that the combo FTP type=A URL, CURLOPT_PORT set and proxy work fine. As a bonus I managed to remove the somewhat odd FTP check in parse_remote_port() and instead converted it to a better and more generic 'slash_removed' struct field. Checking the ->protocol field isn't right since when an FTP:// URL is sent over a HTTP proxy, the protocol is HTTP but the URL was handled by the FTP code and thus slash_removed is set TRUE for this case.

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.
2010-05-05PolarSSL: initial support addedHoi-Ho Chan
This is Hoi-Ho Chan's patch with some minor fixes by me. There are some potential issues in this, but none worse than we can sort out on the list and over time.
2010-04-29telnet: Allow programatic use of telnet.Ben Greear
The main change is to allow input from user-specified methods, when they are specified with CURLOPT_READFUNCTION. All calls to fflush(stdout) in telnet.c were removed, which makes using 'curl telnet://foo.com' painful since prompts and other data are not always returned to the user promptly. Use 'curl --no-buffer telnet://foo.com' instead. In general, the user should have their CURLOPT_WRITEFUNCTION do a fflush for interactive use. Also fix assumption that reading from stdin never returns < 0. Old code could crash in that case. Call progress functions in telnet main loop. Signed-off-by: Ben Greear <greearb@candelatech.com>

2010-01-01update copyright year since we are in 2010 nowDaniel Stenberg
2010-01-01- Ingmar Runge enhanced libcurl's FTP engine to support the PRET command. ThisDaniel Stenberg
command is a special "hack" used by the drftpd server, but even though it is a custom extension I've deemed it fine to add to libcurl since this server seems to survive and people keep using it and want libcurl to support it. The new libcurl option is named CURLOPT_FTP_USE_PRET, and it is also usable from the curl tool with --ftp-pret. Using this option on a server that doesn't support this command will make libcurl fail.
