2016-04-01upload: missing rewind call could make libcurl hangDaniel Stenberg
When an upload is done, there are two places where that can be detected and only one of them would rewind the input stream - which sometimes is necessary for example when doing NTLM HTTP POSTs and more. This could then end up libcurl hanging. Figured-out-by: Isaac Boukris Reported-by: Anatol Belski Fixes #741
2016-03-30multi: multi_reconnect_request is the former Curl_reconnect_requestDaniel Stenberg
now a file local function in multi.c
2016-03-16transfer: Removed redundant HTTP authentication include filesSteve Holme
It would also seem that share.h is not required here either as there are no references to the Curl_share structure or functions.
2016-02-03URLs: change all http:// URLs to https://Daniel Stenberg
2016-01-08http2: Ensure that http2_handle_stream_close is calledTatsuhiro Tsujikawa
Previously, when HTTP/2 is enabled and used, and stream has content length known, Curl_read was not called when there was no bytes left to read. Because of this, we could not make sure that http2_handle_stream_close was called for every stream. Since we use http2_handle_stream_close to emit trailer fields, they were effectively ignored. This commit changes the code so that Curl_read is called even if no bytes left to read, to ensure that http2_handle_stream_close is called for every stream. Discussed in https://github.com/bagder/curl/pull/564
2015-11-02http redirects: %-encode bytes outside of ascii rangeDaniel Stenberg
Apparently there are sites out there that do redirects to URLs they provide in plain UTF-8 or similar. Browsers and wget %-encode such headers when doing a subsequent request. Now libcurl does too. Added test 1138 to verify. Closes #473
2015-10-15fread_func: move callback pointer from set to state structDaniel Stenberg
... and assign it from the set.fread_func_set pointer in the Curl_init_CONNECT function. This A) avoids that we have code that assigns fields in the 'set' struct (which we always knew was bad) and more importantly B) it makes it impossibly to accidentally leave the wrong value for when the handle is re-used etc. Introducing a state-init functionality in multi.c, so that we can set a specific function to get called when we enter a state. The Curl_init_CONNECT is thus called when switching to the CONNECT state. Bug: https://github.com/bagder/curl/issues/346 Closes #346
2015-09-27readwrite_data: set a max number of loopsDaniel Stenberg
... as otherwise a really fast pipe can "lock" one transfer for some protocols, like with HTTP/2.
2015-09-26FTP: fix uploading ASCII with unknown sizeDaniel Stenberg
... don't try to increase the supposed file size on newlines if we don't know what file size it is! Patch-by: lzsiga
2015-07-25HTTP: ignore "Content-Encoding: compress"Michael Kaufmann
Currently, libcurl rejects responses with "Content-Encoding: compress" when CURLOPT_ACCEPT_ENCODING is set to "". I think that libcurl should treat the Content-Encoding "compress" the same as other Content-Encodings that it does not support, e.g. "bzip2". That means just ignoring it.
2015-06-23pretransfer: init state.infilesize here, not in add_handleDaniel Stenberg
... to properly support that options are set to the handle after it is added to the multi handle. Bug: http://curl.haxx.se/mail/lib-2015-06/0122.html Reported-by: Stefan Bühler
2015-06-10debug: remove http2 debug leftoversDaniel Stenberg
2015-05-20read_callback: move to SessionHandle from connectdataDaniel Stenberg
With many easy handles using the same connection for multiplexing, it is important we store and keep the transfer-oriented stuff in the SessionHandle so that callbacks and callback data work fine even when many easy handles share the same physical connection.
2015-05-19transfer: remove erroneous and misleading commentDaniel Stenberg
2015-05-19transfer: Replace __func__ instances with function nameJay Satiro
.. also make __func__ replacement in multi. Prior to this change debug builds would fail to build if the compiler was building pre-c99 and didn't support __func__.
2015-05-18CURLMOPT_PIPELINE: bit 1 is for multiplexingDaniel Stenberg
2015-05-18http2: force "drainage" of streamsDaniel Stenberg
... which is necessary since the socket won't be readable but there is data waiting in the buffer.
2015-05-18http2: move the mem+len pair to the stream structDaniel Stenberg
2015-05-18http2: more stream-oriented data, stream ID 0 is for connectionsDaniel Stenberg
2015-04-07lib/transfer.c: Remove factor of 8 from sleep time calculationDa-Yoon Chung
The factor of 8 is a bytes-to-bits conversion factor, but pkt_size and rate_bps are both in bytes. When using the rate limiting option, curl waits 8 times too long, and then transfers very quickly until the average rate reaches the limit. The average rate follows the limit over time, but the actual traffic is bursty. Thanks-to: Benjamin Gilbert
2015-03-24curl_memory: make curl_memory.h the second-last header file loadedDan Fandrich
This header file must be included after all header files except memdebug.h, as it does similar memory function redefinitions and can be similarly affected by conflicting definitions in system or dependent library headers.

2015-03-17checksrc: use space before paren in "return (expr);"Daniel Stenberg
2015-03-03mprintf.h: remove #ifdef CURLDEBUGDaniel Stenberg
... and as a consequence, introduce curl_printf.h with that re-define magic instead and make all libcurl code use that instead.
2015-01-14Curl_pretransfer: reset expected transfer sizesDaniel Stenberg
Reported-by: Mohammad AlSaleh Bug: http://curl.haxx.se/mail/lib-2015-01/0065.html
2014-11-30transfer: Code style policingSteve Holme
Prefer ! rather than NULL in if statements, added comments and updated function spacing, argument spacing and line spacing to be more readble.
2014-11-30transfer: Fixed existing scratch buffer being checked for NULL twiceSteve Holme
If the scratch buffer already existed when the CRLF conversion was performed then the buffer pointer would be checked twice for NULL. This second check is only necessary if the call to malloc() was performed by the first check.
2014-11-30smtp: Fixed dot stuffing being performed when no new data readSteve Holme
Whilst I had moved the dot stuffing code from being performed before CRLF conversion takes place to after it, in commit 4bd860a001, I had moved it outside the 'when something read' block of code when meant it could perform the dot stuffing twice on partial send if nread happened to contain the right values. It also meant the function could potentially read past the end of buffer. This was highlighted by the following warning: warning: `nread' might be used uninitialized in this function
2014-11-26smtp: Added support for the conversion of Unix newlines during mail sendSteve Holme
Added support for the automatic conversion of Unix newlines to CRLF during mail uploads. Feature: http://curl.haxx.se/bug/view.cgi?id=1456
2014-11-03Curl_single_getsock: fix hold/pause sock handlingCarlo Wood
The previous condition that checked if the socket was marked as readable when also adding a writable one, was incorrect and didn't take the pause bits properly into account.
2014-11-01resume: consider a resume from [content-length] to be OKDaniel Stenberg
Basically since servers often then don't respond well to this and instead send the full contents and then libcurl would instead error out with the assumption that the server doesn't support resume. As the data is then already transfered, this is now considered fine. Test case 1434 added to verify this. Test case 1042 slightly modified.

2014-10-29transfer: drop the code handling the ssl_connect_retry flagKamil Dudka
Its last use has been removed by the previous commit.
2014-10-24code cleanup: we prefer 'CURLcode result'Daniel Stenberg
... for the local variable name in functions holding the return code. Using the same name universally makes code easier to read and follow. Also, unify code for checking for CURLcode errors with: if(result) or if(!result) instead of if(result == CURLE_OK), if(CURLE_OK == result) or if(result != CURLE_OK)
2014-06-09transfer: fix info messages when switching method on 301 and 302Alessandro Ghedini
The method change is forbidden by the obsolete RFC2616, but libcurl did it anyway for compatibility reasons. The new RFC7231 allows this behaviour so there's no need for the scary "Violate RFC 2616/10.3.x" notice. Also update the comments accordingly.
2014-05-22bits.close: introduce connection close trackingDaniel Stenberg
Make all code use connclose() and connkeep() when changing the "close state" for a connection. These two macros take a string argument with an explanation, and debug builds of curl will include that in the debug output. Helps tracking connection re-use/close issues.
2014-04-26INFILESIZE: fields in UserDefined must not be changed run-timeDaniel Stenberg
set.infilesize in this case was modified in several places, which could lead to repeated requests using the same handle to get unintendent/wrong consequences based on what the previous request did!
2014-04-23handler: make 'protocol' always specified as a single bitDaniel Stenberg
This makes the findprotocol() function work as intended so that libcurl can properly be restricted to not support HTTP while still supporting HTTPS - since the HTTPS handler previously set both the HTTP and HTTPS bits in the protocol field. This fixes --proto and --proto-redir for most SSL protocols. This is done by adding a few new convenience defines that groups HTTP and HTTPS, FTP and FTPS etc that should then be used when the code wants to check for both protocols at once. PROTO_FAMILY_[protocol] style. Bug: https://github.com/bagder/curl/pull/97 Reported-by: drizzt
2014-03-14chunked-encoding: provide a readable error string for chunked errorsDaniel Stenberg
2014-02-28transfer.c: Fixed non-HTTP2 builds from commit cde0cf7c5eSteve Holme
2014-02-28Fix bug that HTTP/2 hangs if whole response body is read with headersTatsuhiro Tsujikawa
For HTTP/2, we may read up everything including responde body with header fields in Curl_http_readwrite_headers. If no content-length is provided, curl waits for the connection close, which we emulate it using conn->proto.httpc.closed = TRUE. The thing is if we read everything, then http2_recv won't be called and we cannot signal the HTTP/2 stream has closed. As a workaround, we return nonzero from data_pending to call http2_recv.
2014-02-13transfer: make Expect: 100-continue timeout configurable.Tiit Pikma
Replaced the #define CURL_TIMEOUT_EXPECT_100 in transfer.c with the CURLOPT_EXPECT_100_TIMEOUT_MS option to make the timeout configurable.
2014-02-06100-continue: fix timeout conditionRemi Gacogne
When using the multi socket interface, libcurl calls the curl_multi_timer_callback asking to be woken up after CURL_TIMEOUT_EXPECT_100 milliseconds. After the timeout has expired, calling curl_multi_socket_action with CURL_SOCKET_TIMEOUT as sockfd leads libcurl to check expired timeouts. When handling the 100-continue one, the following check in Curl_readwrite() fails if exactly CURL_TIMEOUT_EXPECT_100 milliseconds passed since the timeout has been set! It seems logical to consider that having waited for exactly CURL_TIMEOUT_EXPECT_100 ms is enough. Bug: http://curl.haxx.se/bug/view.cgi?id=1334
2014-01-12multi: remove MULTI_TIMEOUT_INACCURACYDaniel Stenberg
With the recently added timeout "reminder" functionality, there's no reason left for us to execute timeout code before the time is ripe. Simplifies the handling too. This will make the *TIMEOUT and *CONNECTTIMEOUT options more accurate again, which probably is most important when the *_MS versions are used. In multi_socket, make sure to update 'now' after having handled activity on a socket.
2013-12-31mprintf: Replaced internal usage of FORMAT_OFF_T and FORMAT_OFF_TUSteve Holme
Following commit 0aafd77fa4c6f2, replaced the internal usage of FORMAT_OFF_T and FORMAT_OFF_TU with the external versions that we expect API programmers to use. This negates the need for separate definitions which were subtly different under different platforms/compilers.
2013-12-26FILE: we don't support paused transfers using this protocolDaniel Stenberg
Make sure that we detect such attempts and return a proper error code instead of silently handling this in problematic ways. Updated the documentation to mention this limitation. Bug: http://curl.haxx.se/bug/view.cgi?id=1286
2013-12-20vtls: renamed sslgen.[ch] to vtls.[ch]Daniel Stenberg
2013-12-20vtls: created subdir, moved sslgen.[ch] there, updated all include linesDaniel Stenberg
2013-12-15multi: add timer inaccuracy margin to timeout/connecttimeoutDaniel Stenberg
Since all systems have inaccuracy in the timeout handling it is imperative that we add an inaccuracy margin to the general timeout and connecttimeout handling with the multi interface. This way, when the timeout fires we should be fairly sure that it has passed the timeout value and will be suitably detected. For cases where the timeout fire before the actual timeout, we would otherwise consume the timeout action and still not run the timeout code since the condition wasn't met. Reported-by: He Qin Bug: http://curl.haxx.se/bug/view.cgi?id=1298
2013-10-07HTTP: Output http response 304 when modified time is too oldDerek Higgins
When using the -w '%{http_code}' flag and simulating a Not Modified then 304 should be output.
2013-08-28multi_socket: improved 100-continue timeout handlingDaniel Stenberg
When waiting for a 100-continue response from the server, the Curl_readwrite() will refuse to run if called until the timeout has been reached. We timeout code in multi_socket() allows code to run slightly before the actual timeout time, so for test 154 it could lead to the function being executed but refused in Curl_readwrite() and then the application would just sit idling forever. This was detected with runtests.pl -e on test 154.
