2018-07-31HTTP: Don't attempt to needlessly decompress redirect bodyHarry Sintonen
This change fixes a regression where redirect body would needlessly be decompressed even though it was to be ignored anyway. As it happens this causes secondary issues since there appears to be a bug in apache2 that it in certain conditions generates a corrupt zlib response. The regression was created by commit: dbcced8e32b50c068ac297106f0502ee200a1ebd Discovered-by: Harry Sintonen Closes #2798
2018-06-12Curl_debug: remove dead printhost codeDaniel Stenberg
The struct field is never set (since 5e0d9aea3) so remove the use of it and remove the connectdata pointer from the prototype. Reported-by: Tejas Bug: https://curl.haxx.se/mail/lib-2018-06/0054.html Closes #2647
2018-06-11cppcheck: fix warningsMarian Klymov
- Get rid of variable that was generating false positive warning (unitialized) - Fix issues in tests - Reduce scope of several variables all over etc Closes #2631
2018-05-11setup_transfer: deal with both sockets being -1Daniel Stenberg
Detected by Coverity; CID 1435559. Follow-up to f8d608f38d00. It would index the array with -1 if neither index was a socket.
2018-05-04transfer: don't unset writesockfd on setup of multiplexed connsDaniel Stenberg
Curl_setup_transfer() can be called to setup a new individual transfer over a multiplexed connection so it shouldn't unset writesockfd. Bug: #2520 Closes #2549
2018-05-03URL: fix ASCII dependency in strcpy_url and strlen_urlStephan Mühlstrasser
Commit 3c630f9b0af097663a64e5c875c580aa9808a92b partially reverted the changes from commit dd7521bcc1b7a6fcb53c31f9bd1192fcc884bd56 because of the problem that strcpy_url() was modified unilaterally without also modifying strlen_url(). As a consequence strcpy_url() was again depending on ASCII encoding. This change fixes strlen_url() and strcpy_url() in parallel to use a common host-encoding independent criterion for deciding whether an URL character must be %-escaped. Closes #2535
2018-04-25strcpy_url: only %-encode values >= 0x80Daniel Stenberg
OSS-Fuzz detected https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=8000 Broke in dd7521bcc1b7
2018-04-24ctype: restore character classification for non-ASCII platformsStephan Mühlstrasser
With commit 4272a0b0fc49a1ac0ceab5c4a365c9f6ab8bf8e2 curl-speficic character classification macros and functions were introduced in curl_ctype.[ch] to avoid dependencies on the locale. This broke curl on non-ASCII, e.g. EBCDIC platforms. This change restores the previous set of character classification macros when CURL_DOES_CONVERSIONS is defined. Closes #2494
2018-04-20http2: handle GOAWAY properlyDaniel Stenberg
When receiving REFUSED_STREAM, mark the connection for close and retry streams accordingly on another/fresh connection. Reported-by: Terry Wu Fixes #2416 Fixes #1618 Closes #2510
2018-03-15transfer: make HTTP without headers count correct body sizeDaniel Stenberg
This is what "HTTP/0.9" basically looks like. Reported on IRC Closes #2382
2018-03-12readwrite: make sure excess reads don't go beyond buffer endDaniel Stenberg

Closes #2302
2017-11-05HTTP: support multiple Content-EncodingsPatrick Monnerat
This is implemented as an output streaming stack of unencoders, the last calling the client write procedure. New test 230 checks this feature. Bug: https://github.com/curl/curl/pull/2002 Reported-By: Daniel Bankhead
2017-10-26transfer: Fix chunked-encoding upload bugJay Satiro
- When uploading via chunked-encoding don't compare file size to bytes sent to determine whether the upload has finished. Chunked-encoding adds its own overhead which why the bytes sent is not equal to the file size. Prior to this change if a file was uploaded in chunked-encoding and its size was known it was possible that the upload could end prematurely without sending the final few chunks. That would result in a server hang waiting for the remaining data, likely followed by a disconnect. The scope of this bug is limited to some arbitrary file sizes which have not been determined. One size that triggers the bug is 475020. Bug: https://github.com/curl/curl/issues/2001 Reported-by: moohoorama@users.noreply.github.com Closes https://github.com/curl/curl/pull/2010
2017-10-26wildcards: don't use with non-supported protocolsMax Dymond
Fixes timeouts in the fuzzing tests for non-FTP protocols. Closes #2016
2017-10-25time: rename Curl_tvnow to Curl_nowDaniel Stenberg
... since the 'tv' stood for timeval and this function does not return a timeval struct anymore. Also, cleaned up the Curl_timediff*() functions to avoid typecasts and clean up the descriptive comments. Closes #2011
2017-10-25timediff: return timediff_t from the time diff functionsDaniel Stenberg
... to cater for systems with unsigned time_t variables. - Renamed the functions to curlx_timediff and Curl_timediff_us. - Added overflow protection for both of them in either direction for both 32 bit and 64 bit time_ts - Reprefixed the curlx_time functions to use Curl_* Reported-by: Peter Piekarski Fixes #2004 Closes #2005

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.
