2013-08-06FTP: when EPSV gets a 229 but fails to connect, retry with PASVDaniel Stenberg
This is a regression as this logic used to work. It isn't clear when it broke, but I'm assuming in 7.28.0 when we went all-multi internally. This likely never worked with the multi interface. As the failed connection is detected once the multi state has reached DO_MORE, the Curl_do_more() function was now expanded somewhat so that the ftp_do_more() function can request to go "back" to the previous state when it makes another attempt - using PASV. Added test case 1233 to verify this fix. It has the little issue that it assumes no service is listening/accepting connections on port 1... Reported-by: byte_bucket in the #curl IRC channel
2013-08-03multi: remove data->state.current_conn struct fieldDaniel Stenberg
Not needed
2013-08-03multi: remove the one_easy struct fieldDaniel Stenberg
Since the merge of SessionHandle with Curl_one_easy, this indirection isn't used anymore.
2013-08-03multi: rename all Curl_one_easy to SessionHandleDaniel Stenberg
2013-08-03multi: remove the multi_pos struct fieldDaniel Stenberg
Since Curl_one_easy is really a SessionHandle now, this indirection doesn't exist anymore.
2013-08-03multi: remove easy_handle struct fieldDaniel Stenberg
It isn't needed anymore
2013-08-03multi: remove 'Curl_one_easy' struct, phase 1Daniel Stenberg
The motivation for having a separate struct that keep track of an easy handle when using the multi handle was removed when we switched to always using the multi interface internally. Now they were just two separate struct that was always allocated for each easy handle. This first step just moves the Curl_one_easy struct members into the SessionHandle struct and hides this somehow (== keeps the source code changes to a minimum) by defining Curl_one_easy to SessionHandle The biggest changes in this commit are: 1 - the linked list of easy handles had to be changed somewhat due to the new struct layout. This made the main linked list pointer get renamed to 'easyp' and there's also a new pointer to the last node, called easylp. It is no longer circular but ends with ->next pointing to NULL. New nodes are still added last. 2 - easy->state is now called easy->mstate to avoid name collision
2013-07-18CURLOPT_XFERINFOFUNCTION: introducing a new progress callbackDaniel Stenberg
CURLOPT_XFERINFOFUNCTION is now the preferred progress callback function and CURLOPT_PROGRESSFUNCTION is considered deprecated. This new callback uses pure 'curl_off_t' arguments to pass on full resolution sizes. It otherwise retains the same characteristics: the same call rate, the same meanings for the arguments and the return code is used the same way. The progressfunc.c example is updated to show how to use the new callback for newer libcurls while supporting the older one if built with an older libcurl or even built with a newer libcurl while running with an older.

2013-04-21url: Removed unused text length constantsSteve Holme
2013-04-20url: Added support for parsing login options from the CURLOPT_USERPWDSteve Holme
In addition to parsing the optional login options from the URL, added support for parsing them from CURLOPT_USERPWD, to allow the following supported command line: --user username:password;options
2013-04-13url: Added support for parsing login options from the URLSteve Holme
As well as parsing the username and password from the URL, added support for parsing the optional options part from the login details, to allow the following supported URL format: schema://username:password;options@example.com/path?q=foobar This will only be used by IMAP, POP3 and SMTP at present but any protocol that may be given login options in the URL will be able to add support for them.
2013-04-05Curl_open: restore default MAXCONNECTS to 5Daniel Stenberg
At some point recently we lost the default value for the easy handle's connection cache, and this change puts it back to 5 - which is the former default value and it is documented in the curl_easy_setopt.3 man page.
2013-03-13Multiple pipelines and limiting the number of connections.Linus Nielsen Feltzing
Introducing a number of options to the multi interface that allows for multiple pipelines to the same host, in order to optimize the balance between the penalty for opening new connections and the potential pipelining latency. Two new options for limiting the number of connections: CURLMOPT_MAX_HOST_CONNECTIONS - Limits the number of running connections to the same host. When adding a handle that exceeds this limit, that handle will be put in a pending state until another handle is finished, so we can reuse the connection. CURLMOPT_MAX_TOTAL_CONNECTIONS - Limits the number of connections in total. When adding a handle that exceeds this limit, that handle will be put in a pending state until another handle is finished. The free connection will then be reused, if possible, or closed if the pending handle can't reuse it. Several new options for pipelining: CURLMOPT_MAX_PIPELINE_LENGTH - Limits the pipeling length. If a pipeline is "full" when a connection is to be reused, a new connection will be opened if the CURLMOPT_MAX_xxx_CONNECTIONS limits allow it. If not, the handle will be put in a pending state until a connection is ready (either free or a pipe got shorter). CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE - A pipelined connection will not be reused if it is currently processing a transfer with a content length that is larger than this. CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE - A pipelined connection will not be reused if it is currently processing a chunk larger than this. CURLMOPT_PIPELINING_SITE_BL - A blacklist of hosts that don't allow pipelining. CURLMOPT_PIPELINING_SERVER_BL - A blacklist of server types that don't allow pipelining. See the curl_multi_setopt() man page for details.

Corrected comment for opt_no_body variable to CURLOPT_NOBODY.
2013-02-23imap: Introduced a custom IMAP structure for per-request dataJiri Hruska
Created a new IMAP structure and changed the type of the imap proto variable in connectdata from FTP* to the new IMAP*. Moved the mailbox variable from the per-connection struct imap_conn to the new per-request struct and fixed references accordingly.
2013-02-15PolarSSL: changes to entropy/ctr_drbg/HAVEGE_RANDOMWillem Sparreboom
Add non-threaded entropy and ctr_drbg and removed HAVEGE_RANDOM define
2013-02-12darwinssl: Fix send glitchiness with data > 32 or so KBNick Zitzmann
An ambiguity in the SSLWrite() documentation lead to a bad inference in the code where we assumed SSLWrite() returned the amount of bytes written to the socket, when that is not actually true; it returns the amount of data that is buffered for writing to the socket if it returns errSSLWouldBlock. Now darwinssl_send() returns CURLE_AGAIN if data is buffered but not written. Reference URL: http://curl.haxx.se/mail/lib-2013-02/0145.html
2013-01-17always-multi: always use non-blocking internalsDaniel Stenberg
Remove internal separated behavior of the easy vs multi intercace. curl_easy_perform() is now using the multi interface itself. Several minor multi interface quirks and bugs have been fixed in the process. Much help with debugging this has been provided by: Yang Tse
2013-01-09build: fix circular header inclusion with other packagesYang Tse
This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact.

2012-12-07Introducing a new persistent connection caching system using "bundles".Linus Nielsen Feltzing
A bundle is a list of all persistent connections to the same host. The connection cache consists of a hash of bundles, with the hostname as the key. The benefits may not be obvious, but they are two: 1) Faster search for connections to reuse, since the hash lookup only finds connections to the host in question. 2) It lays out the groundworks for an upcoming patch, which will introduce multiple HTTP pipelines. This patch also removes the awkward list of "closure handles", which were needed to send QUIT commands to the FTP server when closing a connection. Now we allocate a separate closure handle and use that one to close all connections. This has been tested in a live system for a few weeks, and of course passes the test suite.
2012-11-06CURLOPT_SSL_VERIFYHOST: stop supporting the 1 valueDaniel Stenberg
After a research team wrote a document[1] that found several live source codes out there in the wild that misused the CURLOPT_SSL_VERIFYHOST option thinking it was a boolean, this change now bans 1 as a value and will make libcurl return error for it. 1 was never a sensible value to use in production but was introduced back in the days to help debugging. It was always documented clearly this way. 1 was never supported by all SSL backends in libcurl, so this cleanup makes the treatment of it unified. The report's list of mistakes for this option were all PHP code and while there's a binding layer between libcurl and PHP, the PHP team has decided that they have an as thin layer as possible on top of libcurl so they will not alter or specifically filter a 'TRUE' value for this particular option. I sympathize with that position. [1] = http://daniel.haxx.se/blog/2012/10/25/libcurl-claimed-to-be-dangerous/
2012-09-09curl_schannel.c: Reference count the credential/session handleMarc Hoersken
Reference counting the credential handle should avoid that such a handle is freed while it is still required for connection shutdown
2012-07-25darwinssl: fixed freeze involving the multi interfaceNick Zitzmann
Previously the curl_multi interface would freeze if darwinssl was enabled and at least one of the handles tried to connect to a Web site using HTTPS. Removed the "wouldblock" state darwinssl was using because I figured out a solution for our "would block but in which direction?" dilemma.
2012-06-26DarwinSSL: several adjustmentsNick Zitzmann
- Renamed st_ function prefix to darwinssl_ - Renamed Curl_st_ function prefix to Curl_darwinssl_ - Moved the duplicated ssl_connect_done out of the #ifdef in lib/urldata.h - Fixed a teensy little bug that made non-blocking connection attempts block - Made it so that it builds cleanly against the iOS 5.1 SDK

2012-06-14urldata.h: fix cyassl/openssl/ssl.h build clash with wincrypt.hGisle Vanem
Building with CyaSSL failed compilation. Reason being that OCSP_REQUEST and OCSP_RESPONSE are enum values in CyaSSL and defines in <wincrypt.h> included via <winldap.h> in ldap.c. http://curl.haxx.se/mail/lib-2012-06/0196.html
2012-06-11schannel: Code cleanup and bug fixesMarc Hoersken
curl_sspi.c: Fixed mingw32-gcc compiler warnings curl_sspi.c: Fixed length of error code hex output The hex value was printed as signed 64-bit value on 64-bit systems: SEC_E_WRONG_PRINCIPAL (0xFFFFFFFF80090322) It is now correctly printed as the following: SEC_E_WRONG_PRINCIPAL (0x80090322) curl_sspi.c: Fallback to security function table version number Instead of reporting an unknown version, the interface version is used. curl_sspi.c: Removed SSPI/ version prefix from Curl_sspi_version curl_schannel: Replaced static buffer sizes with defined names curl_schannel.c: First brace when declaring functions on column 0 curl_schannel.c: Put the pointer sign directly at variable name curl_schannel.c: Use structs directly instead of typedef'ed structs curl_schannel.c: Removed space before opening brace curl_schannel.c: Fixed lines being longer than 80 chars

2012-04-05PolarSSL: add support for asynchronous connectDag Ekengren
2012-03-22CONNECT: fix multi interface regressionDaniel Stenberg
The refactoring of HTTP CONNECT handling in commit 41b0237834232 that made it protocol independent broke it for the multi interface. This fix now introduce a better state handling and moved some logic to the http_proxy.c source file. Reported by: Yang Tse Bug: http://curl.haxx.se/mail/lib-2012-03/0162.html
2012-02-14smtp_mail: Added support to MAIL FROM for the optional AUTH parameterSteve Holme
Added a new CURLOPT_MAIL_AUTH option that allows the calling program to set the optional AUTH parameter in the MAIL FROM command. When this option is specified and an authentication mechanism is used to communicate with the mail server then the AUTH parameter will be included in the MAIL FROM command. This is particularly useful when the calling program is acting as a relay in a trusted environment and performing server to server communication, as it allows the relaying server to specify the address of the mailbox that was used to authenticate and send the original email.
2012-02-14cyassl: update to CyaSSL 2.0.x APItoddouska
Modify configure.ac to test for new CyaSSL Init function and remove default install path to system. Change to CyaSSL OpenSSL header and proper Init in code as well. Note that this no longer detects or works with CyaSSL before v2
2012-02-09CURLOPT_SSL_OPTIONS: addedDaniel Stenberg
Allow an appliction to set libcurl specific SSL options. The first and only options supported right now is CURLSSLOPT_ALLOW_BEAST. It will make libcurl to disable any work-arounds the underlying SSL library may have to address a known security flaw in the SSL3 and TLS1.0 protocol versions. This is a reaction to us unconditionally removing that behavior after this security advisory: http://curl.haxx.se/docs/adv_20120124B.html ... it did however cause a lot of programs to fail because of old servers not liking this work-around. Now programs can opt to decrease the security in order to interoperate with old servers better.
2012-02-09add library support for tuning TCP_KEEPALIVEDave Reisner
This adds three new options to control the behavior of TCP keepalives: - CURLOPT_TCP_KEEPALIVE: enable/disable probes - CURLOPT_TCP_KEEPIDLE: idle time before sending first probe - CURLOPT_TCP_KEEPINTVL: delay between successive probes While not all operating systems support the TCP_KEEPIDLE and TCP_KEEPINTVL knobs, the library will still allow these options to be set by clients, silently ignoring the values.

2011-12-20FTP: move FTP-specific struct field to ftpc_connDaniel Stenberg
"wait_data_conn" was added to the connectionbits in commit c834213ad5 for handling active FTP connections but as it is purely FTP specific and now only ever accessed by ftp.c I moved it into the FTP connection struct.
