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.
2015-01-17http_negotiate: Return CURLcode in Curl_input_negotiate() instead of intSteve Holme
2014-12-04http_perhapsrewind: don't abort CONNECT requestsStefan Bühler
...they never have a body
2014-12-04HTTP: Free (proxy)userpwd for NTLM/Negotiate after sending a requestStefan Bühler
Sending NTLM/Negotiate header again after successful authentication breaks the connection with certain Proxies and request types (POST to MS Forefront).
2014-12-04HTTP: don't abort connections with pending Negotiate authenticationStefan Bühler
... similarly to how NTLM works as Negotiate is in fact often NTLM with another name.
2014-11-27http.c: Fixed compilation warnings from features being disabledSteve Holme
warning: unused variable 'data' warning: variable 'addcookies' set but not used ...and some very minor coding style policing.
2014-11-20http.c: log if it notices HTTP 1.1 after a upgrade to http2Daniel Stenberg
2014-11-20http: Disable pipelining for HTTP/2 and upgraded connectionsTatsuhiro Tsujikawa
This commit disables pipelining for HTTP/2 or upgraded connections. For HTTP/2, we do not support multiplexing. In general, requests cannot be pipelined in an upgraded connection, since it is now different protocol.
2014-11-15http2: Don't send Upgrade headers when we already do HTTP/2Tatsuhiro Tsujikawa
2014-11-13http2: Deal with HTTP/2 data inside response header bufferTatsuhiro Tsujikawa
Previously if HTTP/2 traffic is appended to HTTP Upgrade response header (thus they are in the same buffer), the trailing HTTP/2 traffic is not processed and lost. The appended data is most likely SETTINGS frame. If it is lost, nghttp2 library complains server does not obey the HTTP/2 protocol and issues GOAWAY frame and curl eventually drops connection. This commit fixes this problem and now trailing data is processed.
2014-11-05http_digest: Use CURLcode instead of CURLdigestSteve Holme
To provide consistent behaviour between the various HTTP authentication functions use CURLcode based error codes for Curl_input_digest() especially as the calling code doesn't use the specific error code just that it failed.
2014-10-27HTTP: return larger than 3 digit response codes tooDaniel Stenberg
HTTP 1.1 is clearly specified to only allow three digit response codes, and libcurl used sscanf("%3d") for that purpose. This made libcurl support smaller numbers but not larger. It does now, but we will not make any specific promises nor document this further since it is going outside of what HTTP is. Bug: http://curl.haxx.se/bug/view.cgi?id=1441 Reported-by: Balaji
2014-10-25ntlm: Only define ntlm data structure when USE_NTLM is definedSteve Holme
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)

2014-09-07Ensure progress.size_dl/progress.size_ul are always >= 0Brandon Casey
Historically the default "unknown" value for progress.size_dl and progress.size_ul has been zero, since these values are initialized implicitly by the calloc that allocates the curl handle that these variables are a part of. Users of curl that install progress callbacks may expect these values to always be >= 0. Currently it is possible for progress.size_dl and progress.size_ul to by set to a value of -1, if Curl_pgrsSetDownloadSize() or Curl_pgrsSetUploadSize() are passed a "size" of -1 (which a few places currently do, and a following patch will add more). So lets update Curl_pgrsSetDownloadSize() and Curl_pgrsSetUploadSize() so they make sure that these variables always contain a value that is >= 0. Updates test579 and test599.

2014-08-15http: fix the Content-Range: parserDaniel Stenberg
... to handle "*/[total]". Also, removed the strange hack that made CURLOPT_FAILONERROR on a 416 response after a *RESUME_FROM return CURLE_OK. Reported-by: Dimitrios Siganos Bug: http://curl.haxx.se/mail/lib-2014-06/0221.html
2014-08-02HTTP2: Support expect: 100-continueTatsuhiro Tsujikawa
"Expect: 100-continue", which was once deprecated in HTTP/2, is now resurrected in HTTP/2 draft 14. This change adds its support to HTTP/2 code. This change also includes stricter header field checking.
2014-07-23http2: more and better error checkingDaniel Stenberg
1 - fixes the warnings when built without http2 support 2 - adds CURLE_HTTP2, a new error code for errors detected by nghttp2 basically when they are about http2 specific things.
2014-07-23docs: Improve inline GSS-API naming in code documentationMichael Osipov
2014-07-23curl.h/features: Deprecate GSS-Negotiate macros due to bad namingMichael Osipov
- Replace CURLAUTH_GSSNEGOTIATE with CURLAUTH_NEGOTIATE - CURL_VERSION_GSSNEGOTIATE is deprecated which is served by CURL_VERSION_SSPI, CURL_VERSION_GSSAPI and CURUL_VERSION_SPNEGO now. - Remove display of feature 'GSS-Negotiate'
2014-07-23HTTP: Remove checkprefix("GSS-Negotiate")Michael Osipov
That auth mech has never existed neither on MS nor on Unix side. There is only Negotiate over SPNEGO.
2014-07-16Fix negotiate auth to proxies to track correct stateDavid Woodhouse
2014-07-16Don't abort Negotiate auth when the server has a response for usDavid Woodhouse
It's wrong to assume that we can send a single SPNEGO packet which will complete the authentication. It's a *negotiation* — the clue is in the name. So make sure we handle responses from the server. Curl_input_negotiate() will already handle bailing out if it thinks the state is GSS_S_COMPLETE (or SEC_E_OK on Windows) and the server keeps talking to us, so we should avoid endless loops that way.
2014-07-16Don't clear GSSAPI state between each exchange in the negotiationDavid Woodhouse
GSSAPI doesn't work very well if we forget everything ever time. XX: Is Curl_http_done() the right place to do the final cleanup?

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.
2014-05-20http2: make connection re-use workDaniel Stenberg
Http2 connections would wrongly get closed after each individual request. Co-authored-by: Tatsuhiro Tsujikawa Bug: http://curl.haxx.se/bug/view.cgi?id=1374
2014-05-15HTTP: CREDSPERREQUEST is for HTTP tooDaniel Stenberg
Commit 517b06d657ace (in 7.36.0) that brought the CREDSPERREQUEST flag only set it for HTTPS, making HTTP less good at doing connection re-use than it should be. Now set it for HTTP as well.

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
2014-04-04PROXYHEADER: send these headers in "normal" proxy requests tooDaniel Stenberg
Updated the docs to clarify and the code accordingly, with test 1528 to verify: When CURLHEADER_SEPARATE is set and libcurl is asked to send a request to a proxy but it isn't CONNECT, then _both_ header lists (CURLOPT_HTTPHEADER and CURLOPT_PROXYHEADER) will be used since the single request is then made for both the proxy and the server.
2014-04-04CURLOPT_HEADEROPT: addedDaniel Stenberg
Modified the logic so that CURLOPT_HEADEROPT now controls if PROXYHEADER is actually used or not.

2014-03-31http2: remove _DRAFT09 from the NPN_HTTP2 enumDaniel Stenberg

2014-03-25url: Fixed connection re-use when using different log-in credentialsSteve Holme
In addition to FTP, other connection based protocols such as IMAP, POP3, SMTP, SCP, SFTP and LDAP require a new connection when different log-in credentials are specified. Fixed the detection logic to include these other protocols. Bug: http://curl.haxx.se/docs/adv_20140326A.html
2014-03-19polarssl: fix possible handshake timeout issue in multi.Gaël PORTAY
Because of the socket is unblocking, PolarSSL does need call to getsock to get the action to perform in multi environment. In some cases, it might happen we have not received yet all data to perform the handshake. ssh_handshake returns POLARSSL_ERR_NET_WANT_READ, the state is updated but because of the getsock has not the proper #define macro to, the library never prevents to select socket for input thus the socket will never be awaken when last data is available. Thus it leads to timeout.
2014-02-17http2: Support HTTP POST/PUTTatsuhiro Tsujikawa
This patch enables HTTP POST/PUT in HTTP2. We disabled Expect header field and chunked transfer encoding since HTTP2 forbids them. In HTTP1, Curl sends small upload data with request headers, but HTTP2 requires upload data must be in DATA frame separately. So we added some conditionals to achieve this.
2014-02-05http2: rely on content-encoding headerFabian Frank
A server might respond with a content-encoding header and a response that was encoded accordingly in HTTP-draft-09/2.0 mode, even if the client did not send an accept-encoding header earlier. The server might not send a content-encoding header if the identity encoding was used to encode the response. See: http://tools.ietf.org/html/draft-ietf-httpbis-http2-09#section-9.3
2014-02-04HTTP2: add layer between existing http and socket(TLS) layerTatsuhiro Tsujikawa
This patch chooses different approach to integrate HTTP2 into HTTP curl stack. The idea is that we insert HTTP2 layer between HTTP code and socket(TLS) layer. When HTTP2 is initialized (either in NPN or Upgrade), we replace the Curl_recv/Curl_send callbacks with HTTP2's, but keep the original callbacks in http_conn struct. When sending serialized data by nghttp2, we use original Curl_send callback. Likewise, when reading data from network, we use original Curl_recv callback. In this way we can treat both TLS and non-TLS connections. With this patch, one can transfer contents from https://twitter.com and from nghttp2 test server in plain HTTP as well. The code still has rough edges. The notable one is I could not figure out how to call nghttp2_session_send() when underlying socket is writable.
2014-01-30http2: switch into http2 mode if NPN indicatesFabian Frank
Check the NPN result before preparing an HTTP request and switch into HTTP/2.0 mode if necessary. This is a work in progress, the actual code to prepare and send the request using nghttp2 is still missing from Curl_http2_send_request().

2014-01-20HTTP POST: omit Content-Length if data size is unknownCédric Deltheil
This prevents sending a `Content-Length: -1` header, e.g this ocurred with the following combination: * standard HTTP POST (no chunked encoding), * user-defined read function set, * `CURLOPT_POSTFIELDSIZE(_LARGE)` NOT set. With this fix it now behaves like HTTP PUT.
