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.

2011-09-08libssh2: use calloc as alloc function for libssh2 versions older than 1.3Yang Tse
This workarounds old libssh2 versions not properly initializing some ssh session variables, which would trigger memory debuggers warnings on memory being used without having been initialized.

2011-08-19tcpconnect: follow-up commit after b998d95bDaniel Stenberg
As I modified conn->bits.tcpconnect to become an array that holds one bool for each potential connection all uses of that struct field must index it correctly.

2011-06-04Curl_socket_ready: make timeout a 'long'Daniel Stenberg
It was mostly typecasted to int all over the code so switching to long instead all over should be a net gain.

2011-05-05RTSP: convert protocol-specific checks to genericDaniel Stenberg
Add a 'readwrite' function to the protocol handler struct and use that for the extra readwrite functionality RTSP needs.
2011-05-01SSH: set non-blocking earlierDaniel Stenberg
Introduce an INIT state for the SSH state machine and set libssh2 non-blocking in that so that it is set properly before libssh2_session_startup() is called. Bug: http://curl.haxx.se/mail/archive-2011-05/0001.html

2011-04-27source cleanup: unify look, style and indent levelsDaniel Stenberg
By the use of a the new lib/checksrc.pl script that checks that our basic source style rules are followed.
2011-04-20SFTP: close file before postquoteDaniel Stenberg
Make sure that files are closed before the post quote commands run as if they operate on the just transferred file they could otherwise easily fail. Patch by: Rajesh Naganathan (edited)
2011-04-20CURL_DOES_CONVERSIONS: cleanupDaniel Stenberg
Massively reduce #ifdefs all over (23 #ifdef lines less so far) Moved conversion-specific code to non-ascii.c
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.
2011-03-13ssh_statemach_act: set cselect for sftp uploadDaniel Stenberg
For uploads we want to use the _sending_ function even when the socket turns out readable as the underlying libssh2 sftp send function will deal with both accordingly. This is what the cselect_bits magic is for. Fixes test 582.
2011-03-13SFTP: gracefully handle shutdown earlyDaniel Stenberg
When using the multi interface and a handle using SFTP was removed very early on, we would get a segfault due to the code assumed data was there that hadn't yet been setup. Bug: http://curl.haxx.se/mail/lib-2011-03/0066.html Reported by: Saqib Ali
2011-03-12sftp upload: expire to advance state machineDaniel Stenberg
When using the multi_socket API to do SFTP upload, it is important that we set a quick expire when leaving the SSH_SFTP_UPLOAD_INIT state as there's nothing happening on the socket so there's no read or write to wait for, but the next libssh2 API function needs to be called to get the ball rolling. This is one of the problems detected by test 582. Reported by: Henry Ludemann <misc@hl.id.au>
2011-02-26ssh_connect: treat libssh2 return code betterDaniel Stenberg
libssh2_knownhost_readfile() returns a negative value on error or otherwise number of parsed known hosts - this was previously not documented correctly in the libssh2 man page for the function. Bug: http://curl.haxx.se/mail/lib-2011-02/0327.html Reported by: murat
2011-01-06SSH: speedcheck clobbered existing errorDaniel Stenberg
The just added speedcheck must not ruin the error code if already set due to a problem.
2011-01-05SSH: acknowledge speedcheckDaniel Stenberg
Check for speedcheck limits during the state machine traversals
2011-01-04Curl_timeleft: s/conn/data in first argumentDaniel Stenberg
As the function doesn't really use the connectdata struct but only the SessionHanadle struct I modified what argument it wants.
2011-01-03SSH: avoid PATH_MAX with allocDaniel Stenberg
We cannot assume that PATH_MAX will be enough for the remote path name so allocating room for it is the only sensible approach.
2011-01-01SFTP: make pwd output result to header callbackDaniel Stenberg
Sending "pwd" as a QUOTE command only sent the reply to the DEBUGFUNCTION. Now it also sends an FTP-like header to the header callback to allow similar operations as with FTP, and apps can re-use the same parser.

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.

2010-10-20SSH: use libssh2_session_handshake()Daniel Stenberg
In libssh2 1.2.8, libssh2_session_handshake() replaces libssh2_session_startup() to fix the previous portability problem with the socket type that was too small for win64 and thus easily could cause crashes and more.
2010-10-20SSH: avoid using the libssh2_ prefixDaniel Stenberg
It is a bad idea to use the public prefix used by another library and now we realize that libssh2 introduces a symbol in the upcoming version 1.2.8 that conflicts with our static function named libssh2_free.
2010-10-12SFTP: more ignoring negative file sizesDaniel Stenberg
As the change in 5f0ae7a0626cbe709 added a precaution against negative file sizes that for some reason managed to get returned, this change now introduces the same check at the second place in the code where the file size from the libssh2 stat call is used. This check might not be suitable for a 32 bit curl_off_t, but libssh2.h assumes long long to work and to be 64 bit so I believe such a small curl_off_t will be very unlikely to occur in the wild.
2010-09-30SFTP: avoid downloading negative sizes!Daniel Stenberg
It is still not clarified exactly why this happens, but libssh2 sometimes report a negative file size for the remote SFTP file and that deeply confuses libcurl (or crashes it) so this precaution is added to avoid badness. Reported by: Ernest Beinrohr Bug: http://curl.haxx.se/bug/view.cgi?id=3076430

2010-08-04SCP: send large files properly with new enough libssh2Daniel Stenberg
libssh2 1.2.6 and later handle >32bit file sizes properly even on 32bit architectures and we make sure to use that ability. Reported by: Mikael Johansson Bug: http://curl.haxx.se/mail/lib-2010-08/0052.html

2010-06-02SSH: corrected the inability to respect the timeoutDaniel Stenberg
Jason McDonald posted bug report #3006786 when he found that the SFTP code didn't timeout properly in several places in the code even if a timeout was set properly. Based on his suggested patch, I wrote a different implementation that I think addressed the issue better and also uses the connect timeout for the initial part of the SSH/SFTP done during the "protocol connect" phase. (http://curl.haxx.se/bug/view.cgi?id=3006786)
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.
2010-04-16Curl_setup_transfer: no longer returns anythingDaniel Stenberg
This function could only return CURLE_OK and by changing it to a void instead, we can simplify code all over.
