2016-08-28http2: make sure stream errors don't needlessly close the connectionDaniel Stenberg
With HTTP/2 each transfer is made in an indivial logical stream over the connection, making most previous errors that caused the connection to get forced-closed now instead just kill the stream and not the connection. Fixes #941
2016-08-04multi: make Curl_expire() work with 0 ms timeoutsDaniel Stenberg
Previously, passing a timeout of zero to Curl_expire() was a magic code for clearing all timeouts for the handle. That is now instead made with the new Curl_expire_clear() function and thus a 0 timeout is fine to set and will trigger a timeout ASAP. This will help removing short delays, in particular notable when doing HTTP/2.
2016-08-04transfer: return without select when the read loop reached maxcountDaniel Stenberg
Regression added in 790d6de48515. The was then added to avoid one particular transfer to starve out others. But when aborting due to reading the maxcount, the connection must be marked to be read from again without first doing a select as for some protocols (like SFTP/SCP) the data may already have been read off the socket.

2016-08-03curl_multi_cleanup: clear connection pointer for easy handlesDaniel Stenberg
CVE-2016-5421 Bug: https://curl.haxx.se/docs/adv_20160803C.html Reported-by: Marcelo Echeverria and Fernando Muñoz
2016-06-22typedefs: use the full structs in internal code...Daniel Stenberg
... and save the typedef'ed names for headers and external APIs.
2016-06-22internals: rename the SessionHandle struct to Curl_easyDaniel Stenberg
2016-05-15ftp wildcard: segfault due to init only in multi_performDaniel Stenberg
The proper FTP wildcard init is now more properly done in Curl_pretransfer() and the corresponding cleanup in Curl_close(). The previous place of init/cleanup code made the internal pointer to be NULL when this feature was used with the multi_socket() API, as it was made within the curl_multi_perform() function. Reported-by: Jonathan Cardoso Machado Fixes #800
2016-04-29lib: include curl_printf.h as one of the last headersDaniel Stenberg
curl_printf.h defines printf to curl_mprintf, etc. This can cause problems with external headers which may use __attribute__((format(printf, ...))) markers etc. To avoid that they cause problems with system includes, we include curl_printf.h after any system headers. That makes the three last headers to always be, and we keep them in this order: curl_printf.h curl_memory.h memdebug.h None of them include system headers, they all do funny #defines. Reported-by: David Benjamin Fixes #743
2016-04-25multi: accidentally used resolved host name instead of proxyDaniel Stenberg
Regression introduced in 09b5a998 Bug: https://curl.haxx.se/mail/lib-2016-04/0084.html Reported-by: BoBo
2016-04-17news: CURLOPT_CONNECT_TO and --connect-toMichael Kaufmann
Makes curl connect to the given host+port instead of the host+port found in the URL.
2016-04-11http2: Add handling stream level errorTatsuhiro Tsujikawa
Previously, when a stream was closed with other than NGHTTP2_NO_ERROR by RST_STREAM, underlying TCP connection was dropped. This is undesirable since there may be other streams multiplexed and they are very much fine. This change introduce new error code CURLE_HTTP2_STREAM, which indicates stream error that only affects the relevant stream, and connection should be kept open. The existing CURLE_HTTP2 means connection error in general. Ref: https://github.com/curl/curl/issues/659 Ref: https://github.com/curl/curl/pull/663
2016-04-05multi: remove trailing space in debug outputDaniel Stenberg
2016-04-03code: style updatesDaniel Stenberg
2016-03-30multi: turn Curl_done into file local multi_doneDaniel Stenberg
... as it now is used by multi.c only.
2016-03-30multi: multi_reconnect_request is the former Curl_reconnect_requestDaniel Stenberg
now a file local function in multi.c
2016-03-30multi: move Curl_do and Curl_do_done to multi.c and make staticDaniel Stenberg
... called multi_do and multi_do_done as they're file local now.
2016-03-23multi: fix "Operation timed out after" timerDaniel Stenberg
Use the local, reasonably updated, 'now' value when creating the message string to output for the timeout condition. Fixes #619
2016-03-14multi: simplified singlesocketDaniel Stenberg
Since sh_getentry() now checks for invalid sockets itself and by narrowing the scope of the remove_sock_from_hash variable.
2016-03-14multi: introduce sh_getentry() for looking up sockets in the sockhashDaniel Stenberg
Simplify the code by using a single entry that looks for a socket in the socket hash. As indicated in #712, the code looked for CURL_SOCKET_BAD at some point and that is ineffective/wrong and this makes it easier to avoid that.
2016-03-14multi hash: ensure modulo performed on curl_socket_tJaime Fullaondo
Closes #712
2016-03-13multi_runsingle: avoid loop in CURLM_STATE_WAITPROXYCONNECTMaksim Kuzevanov
Closes #703
2016-03-10curl_multi_wait: never return -1 in 'numfds'Daniel Stenberg
Such a return value isn't documented but could still happen, and the curl tool code checks for it. It would happen when the underlying Curl_poll() function returns an error. Starting now we mask that error as a user of curl_multi_wait() would have no way to handle it anyway. Reported-by: Jay Satiro Closes #707
2016-02-23multi_remove_handle: keep the timeout list until after disconnectDaniel Stenberg
The internal Curl_done() function uses Curl_expire() at times and that uses the timeout list. Better clean up the list once we're done using it. This caused a segfault. Reported-by: 蔡文凱 Bug: https://curl.haxx.se/mail/lib-2016-02/0097.html
2016-02-03URLs: change all http:// URLs to https://Daniel Stenberg
2015-10-16multi: fix off-by-one finit[] array sizeDaniel Stenberg
introduced in c6aedf680f6. It needs to be CURLM_STATE_LAST big since it must hande the range 0 .. CURLM_STATE_MSGSENT (18) and CURLM_STATE_LAST is 19 right now. Reported-by: Dan Fandrich Bug: http://curl.haxx.se/mail/lib-2015-10/0069.html
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

2015-06-10debug: 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: 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__.
2015-05-18hostip: fix unintended destruction of hash tableAnthony Avina
.. and added unit1602 for hash.c
2015-05-18pipeline: switch some code over to functionsDaniel Stenberg
... to "compartmentalize" a bit and make it easier to change behavior when multiplexing is used instead of good old pipelining.
2015-05-18http2: set default concurrency, fix ConnectionExists for multiplexDaniel Stenberg
2015-05-18bundles: store no/default/pipeline/multiplexDaniel Stenberg
to allow code to act differently on the situation. Also added some more info message for the connection re-use function to make it clearer when connections are not re-used.
2015-05-18http2: separate multiplex/pipelining + cleanup memory leaksDaniel Stenberg
2015-05-18CURLMOPT_PIPELINE: bit 1 is for multiplexingDaniel Stenberg
2015-05-18http2: leave WAITPERFORM when conn is multiplexedDaniel Stenberg
No need to wait for our "spot" like for pipelining
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.
2015-05-12bundles: merged into conncache.cDaniel Stenberg
All the existing Curl_bundle* functions were only ever used from within the conncache.c file, so I moved them over and made them static (and removed the Curl_ prefix).
2015-05-12hostcache: made all host caches use structs, not pointersDaniel Stenberg
This avoids unnecessary dynamic allocs and as this also removed the last users of *hash_alloc() and *hash_destroy(), those two functions are now removed.
2015-05-12multi: converted socket hash into non-allocated structDaniel Stenberg
avoids extra dynamic allocation
2015-05-12connection cache: avoid Curl_hash_alloc()Daniel Stenberg
... by using plain structs instead of pointers for the connection cache, we can avoid several dynamic allocations that weren't necessary.

2015-04-03move Curl_share_lock and ref counting into Curl_fetch_addrStefan Bühler
2015-03-29multi: remove_handle: move pending connectionsDaniel Stenberg
If the handle removed from the multi handle happens to be the one "owning" the pipeline other transfers will be waiting indefinitely. Now we move such handles back to connect to have them race (again) for getting the connection and thus avoid hanging. Bug: http://curl.haxx.se/bug/view.cgi?id=1465 Reported-by: Jiri Dvorak
2015-03-26multi: on a request completion, check all CONNECT_PEND transfersDaniel Stenberg
... even if they don't have an associated connection anymore. It could leave the waiting transfers pending with no active one on the connection. Bug: http://curl.haxx.se/bug/view.cgi?id=1465 Reported-by: Jiri Dvorak
