2017-09-11Curl_checkheaders: make it available for IMAP and SMTP tooDaniel Stenberg
... not only HTTP uses this now. Closes #1875
2017-09-05mime: unified to use the typedef'd mime structs everywhereDaniel Stenberg
... and slightly edited to follow our code style better.
2017-09-02mime: new MIME API.Patrick Monnerat
Available in HTTP, SMTP and IMAP. Deprecates the FORM API. See CURLOPT_MIMEPOST. Lib code and associated documentation.
2017-08-15progress: Track total times following redirectsRyan Winograd
Update the progress timers `t_nslookup`, `t_connect`, `t_appconnect`, `t_pretransfer`, and `t_starttransfer` to track the total times for these activities when a redirect is followed. Previously, only the times for the most recent request would be tracked. Related changes: - Rename `Curl_pgrsResetTimesSizes` to `Curl_pgrsResetTransferSizes` now that the function only resets transfer sizes and no longer modifies any of the progress timers. - Add a bool to the `Progress` struct that is used to prevent double-counting `t_starttransfer` times. Added test case 1399. Fixes #522 and Known Bug 1.8 Closes #1602 Reported-by: joshhe on github
2017-08-13redirect: skip URL encoding for host namesSalah-Eddin Shaban
This fixes redirects to IDN URLs Fixes #1441 Closes #1762 Reported by: David Lord
2017-07-03url: make the original string get used on subsequent transfersDaniel Stenberg
... since CURLOPT_URL should follow the same rules as other options: they remain set until changed or cleared. Added test 1551 to verify. Fixes #1631 Closes #1632 Reported-by: Pavel Rochnyak
2017-05-30transfer: init the infilesize from the postfields...Daniel Stenberg
... with a strlen() if no size was set, and do this in the pretransfer function so that the info is set early. Otherwise, the default strlen() done on the POSTFIELDS data never sets state.infilesize. Reported-by: Vincas Razma Bug: #1294
2017-05-23redirect: store the "would redirect to" URL when max redirs is reachedDaniel Stenberg
Test 1261 added to verify. Reported-by: Lloyd Fournier Fixes #1489 Closes #1497
2017-05-10multi: use a fixed array of timers instead of mallocDaniel Stenberg
... since the total amount is low this is faster, easier and reduces memory overhead. Also, Curl_expire_done() can now mark an expire timeout as done so that it never times out. Closes #1472
2017-05-10multi: assign IDs to all timers and make each timer singletonDaniel Stenberg
A) reduces the timeout lists drastically B) prevents a lot of superfluous loops for timers that expires "in vain" when it has actually already been extended to fire later on
2017-05-01buffer: use data->set.buffer_size instead of BUFSIZEDaniel Stenberg
... to properly use the dynamically set buffer size!
2017-05-01upload: UPLOAD_BUFSIZE is now for the upload bufferDaniel Stenberg
2017-05-01transfer: fix minor buffer_size mistakeDaniel Stenberg
2017-04-25transfer: remove 'uploadbuf' pointer and cleanup readwrite_upload()Daniel Stenberg
The data->req.uploadbuf struct member served no good purpose, instead we use ->state.uploadbuffer directly. It makes it clearer in the code which buffer that's being used. Removed the 'SingleRequest *' argument from the readwrite_upload() proto as it can be derived from the Curl_easy struct. Also made the code in the readwrite_upload() function use the 'k->' shortcut to all references to struct fields in 'data->req', which previously was made with a mix of both.
2017-04-04llist: replace Curl_llist_alloc with Curl_llist_initDaniel Stenberg
No longer allocate the curl_llist head struct for lists separately. Removes 17 (15%) tiny allocations in a normal "curl localhost" invoke. closes #1381

2017-02-07transfer: only retry nobody-requests for HTTPMarkus Westerlind
Using sftp to delete a file with CURLOPT_NOBODY set with a reused connection would fail as curl expected to get some data. Thus it would retry the command again which fails as the file has already been deleted. Fixes #1243

2016-11-24proxy: Support HTTPS proxy and SOCKS+HTTP(s)Alex Rousskov
* HTTPS proxies: An HTTPS proxy receives all transactions over an SSL/TLS connection. Once a secure connection with the proxy is established, the user agent uses the proxy as usual, including sending CONNECT requests to instruct the proxy to establish a [usually secure] TCP tunnel with an origin server. HTTPS proxies protect nearly all aspects of user-proxy communications as opposed to HTTP proxies that receive all requests (including CONNECT requests) in vulnerable clear text. With HTTPS proxies, it is possible to have two concurrent _nested_ SSL/TLS sessions: the "outer" one between the user agent and the proxy and the "inner" one between the user agent and the origin server (through the proxy). This change adds supports for such nested sessions as well. A secure connection with a proxy requires its own set of the usual SSL options (their actual descriptions differ and need polishing, see TODO): --proxy-cacert FILE CA certificate to verify peer against --proxy-capath DIR CA directory to verify peer against --proxy-cert CERT[:PASSWD] Client certificate file and password --proxy-cert-type TYPE Certificate file type (DER/PEM/ENG) --proxy-ciphers LIST SSL ciphers to use --proxy-crlfile FILE Get a CRL list in PEM format from the file --proxy-insecure Allow connections to proxies with bad certs --proxy-key KEY Private key file name --proxy-key-type TYPE Private key file type (DER/PEM/ENG) --proxy-pass PASS Pass phrase for the private key --proxy-ssl-allow-beast Allow security flaw to improve interop --proxy-sslv2 Use SSLv2 --proxy-sslv3 Use SSLv3 --proxy-tlsv1 Use TLSv1 --proxy-tlsuser USER TLS username --proxy-tlspassword STRING TLS password --proxy-tlsauthtype STRING TLS authentication type (default SRP) All --proxy-foo options are independent from their --foo counterparts, except --proxy-crlfile which defaults to --crlfile and --proxy-capath which defaults to --capath. Curl now also supports %{proxy_ssl_verify_result} --write-out variable, similar to the existing %{ssl_verify_result} variable. Supported backends: OpenSSL, GnuTLS, and NSS. * A SOCKS proxy + HTTP/HTTPS proxy combination: If both --socks* and --proxy options are given, Curl first connects to the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS proxy. TODO: Update documentation for the new APIs and --proxy-* options. Look for "Added in 7.XXX" marks.
2016-11-18lib: fix compiler warnings after de4de4e3c7cMarcel Raad
Visual C++ now complains about implicitly casting time_t (64-bit) to long (32-bit). Fix this by changing some variables from long to time_t, or explicitly casting to long where the public interface would be affected. Closes #1131
2016-10-31strcasecompare: all case insensitive string compares ignore locale nowDaniel Stenberg
We had some confusions on when each function was used. We should not act differently on different locales anyway.
2016-10-31strcasecompare: is the new name for strequal()Daniel Stenberg
... to make it less likely that we forget that the function actually does case insentive compares. Also replaced several invokes of the function with a plain strcmp when case sensitivity is not an issue (like comparing with "-").
2016-10-18select: switch to macros in uppercaseDaniel Stenberg
Curl_select_ready() was the former API that was replaced with Curl_select_check() a while back and the former arg setup was provided with a define (in order to leave existing code unmodified). Now we instead offer SOCKET_READABLE and SOCKET_WRITABLE for the most common shortcuts where only one socket is checked. They're also more visibly macros.
2016-09-11http: refuse to pass on response body with NO_NODY was setDaniel Stenberg
... like when a HTTP/0.9 response comes back without any headers at all and just a body this now prevents that body from being sent to the callback etc. Adapted test 1144 to verify. Fixes #973 Assisted-by: Ray Satiro
2016-09-05http2: return EOF when done uploading without known sizeDaniel Stenberg
Fixes #982
2016-09-04speed caps: not based on average speeds anymoreOlivier Brunel
Speed limits (from CURLOPT_MAX_RECV_SPEED_LARGE & CURLOPT_MAX_SEND_SPEED_LARGE) were applied simply by comparing limits with the cumulative average speed of the entire transfer; While this might work at times with good/constant connections, in other cases it can result to the limits simply being "ignored" for more than "short bursts" (as told in man page). Consider a download that goes on much slower than the limit for some time (because bandwidth is used elsewhere, server is slow, whatever the reason), then once things get better, curl would simply ignore the limit up until the average speed (since the beginning of the transfer) reached the limit. This could prove the limit useless to effectively avoid using the entire bandwidth (at least for quite some time). So instead, we now use a "moving starting point" as reference, and every time at least as much as the limit as been transferred, we can reset this starting point to the current position. This gets a good limiting effect that applies to the "current speed" with instant reactivity (in case of sudden speed burst). Closes #971
2016-08-11HTTP: retry failed HEAD requests tooDaniel Stenberg
Mark's new document about HTTP Retries (https://mnot.github.io/I-D/httpbis-retry/) made me check our code and I spotted that we don't retry failed HEAD requests which seems totally inconsistent and I can't see any reason for that separate treatment. So, no separate treatment for HEAD starting now. A HTTP request sent over a reused connection that gets cut off before a single byte is received will be retried on a fresh connection.

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. Reported-by: Dan Donahue Bug: https://curl.haxx.se/mail/lib-2016-07/0057.html
2016-06-22internals: rename the SessionHandle struct to Curl_easyDaniel Stenberg
2016-05-15ftp: fix incorrect out-of-memory code in Curl_pretransferJay Satiro
- Return value type must match function type. s/CURLM_OUT_OF_MEMORY/CURLE_OUT_OF_MEMORY/ Caught by Travis CI
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
2016-04-03code: style updatesDaniel Stenberg
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
