2018-06-23multi: fix crash due to dangling entry in connect-pending listJavier Blazquez
Fixes #2677 Closes #2679
2018-06-16multi: fix memory leak when stopped during name resolveDaniel Stenberg
When the application just started the transfer and then stops it while the name resolve in the background thread hasn't completed, we need to wait for the resolve to complete and then cleanup data accordingly. Enabled test 1553 again and added test 1590 to also check when the host name resolves successfully. Detected by OSS-fuzz. Closes #1968
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
2018-06-03spelling fixesViktor Szakats
Detected using the `codespell` tool (version 1.13.0). Also secure and fix an URL.
2018-06-01multi: remove a DEBUGF()Daniel Stenberg
... it might call infof() with a NULL first argument that isn't harmful but makes it not do anything. The infof() line is not very useful anymore, it has served it purpose. Good riddance! Fixes #2627
2018-05-31strictness: correct {infof, failf} format specifiersRikard Falkeborn
Closes #2623
2018-05-28psl: use latest psl and refresh it periodicallyPatrick Monnerat
The latest psl is cached in the multi or share handle. It is refreshed before use after 72 hours. New share lock CURL_LOCK_DATA_PSL controls the psl cache sharing. If the latest psl is not available, the builtin psl is used. Reported-by: Yaakov Selkowitz Fixes #2553 Closes #2601
2018-04-27checksrc: force indentation of lines after an elseDaniel Gustafsson
This extends the INDENTATION case to also handle 'else' statements and require proper indentation on the following line. Also fixes the offending cases found in the codebase. Closes #2532
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
2018-03-17add_handle/easy_perform: clear errorbuffer on start if setDaniel Stenberg
To offer applications a more defined behavior, we clear the buffer as early as possible. Assisted-by: Jay Satiro Fixes #2190 Closes #2377
2018-03-16multi: improved pending transfers handling => improved performanceDaniel Stenberg
When a transfer is requested to get done and it is put in the pending queue when limited by number of connections, total or per-host, libcurl would previously very aggressively retry *ALL* pending transfers to get them transferring. That was very time consuming. By reducing the aggressiveness in how pending are being retried, we waste MUCH less time on putting transfers back into pending again. Some test cases got a factor 30(!) speed improvement with this change. Reported-by: Cyril B Fixes #2369 Closes #2383
2018-03-16pause: when changing pause state, update socket stateDaniel Stenberg
Especially unpausing a transfer might have to move the socket back to the "currently used sockets" hash to get monitored. Otherwise it would never get any more data and get stuck. Easily triggered with pausing using the multi_socket API. Reported-by: Philip Prindeville Bug: https://curl.haxx.se/mail/lib-2018-03/0048.html Fixes #2393 Closes #2391
2018-03-16rate-limit: use three second window to better handle high speedsDaniel Stenberg
Due to very frequent updates of the rate limit "window", it could attempt to rate limit within the same milliseconds and that then made the calculations wrong, leading to it not behaving correctly on very fast transfers. This new logic updates the rate limit "window" to be no shorter than the last three seconds and only updating the timestamps for this when switching between the states TOOFAST/PERFORM. Reported-by: 刘佩东 Fixes #2386 Closes #2388
2018-03-12http2: mark the connection for close on GOAWAYDaniel Stenberg
... don't consider it an error! Assisted-by: Jay Satiro Reported-by: Łukasz Domeradzki Fixes #2365 Closes #2375
2018-02-15TODO fixed: Detect when called from within callbacksBjörn Stenberg
Closes #2302
2018-01-18http2: don't close connection when single transfer is stoppedKartik Mahajan
Fixes #2237 Closes #2249
2017-12-10multi_done: prune DNS cacheDaniel Stenberg
Prune the DNS cache immediately after the dns entry is unlocked in multi_done. Timed out entries will then get discarded in a more orderly fashion. Test506 is updated Reported-by: Oleg Pudeyev Fixes #2169 Closes #2170
2017-12-05conncache: fix several lock issuesDaniel Stenberg
If the lock is released before the dealings with the bundle is over, it may have changed by another thread in the mean time. Fixes #2132 Fixes #2151 Closes #2139
2017-11-09share: add support for sharing the connection cacheDaniel Stenberg
2017-10-28Curl_timeleft: change return type to timediff_tDaniel Stenberg
returning 'time_t' is problematic when that type is unsigned and we return values less than zero to signal "already expired", used in several places in the code. Closes #2021
2017-10-26wildcards: don't use with non-supported protocolsMax Dymond
Fixes timeouts in the fuzzing tests for non-FTP protocols. Closes #2016
2017-10-25multi: allow table handle sizes to be overriddenMax Dymond
Allow users to specify their own hash define for CURL_CONNECTION_HASH_SIZE so that both values can be overridden. Closes #1982
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
2017-10-08Revert "multi_done: wait for name resolve to finish if still ongoing"Daniel Stenberg
This reverts commit f3e03f6c0ac52a1bf396e03f7d7e9b5b3b7165fe. Caused memory leaks in the fuzzer, needs to be done differently. Disable test 1553 for now too, as it causes memory leaks without this commit!
2017-10-07remove_handle: call multi_done() first, then clear dns cache pointerDaniel Stenberg
Closes #1960
2017-10-07multi_done: wait for name resolve to finish if still ongoingDaniel Stenberg
... as we must clean up memory.
2017-10-06multi_cleanup: call DONE on handles that never got thatDaniel Stenberg
... fixes a memory leak with at least IMAP when remove_handle is never called and the transfer is abruptly just abandoned early. Test 1552 added to verify Detected by OSS-fuzz Assisted-by: Max Dymond Closes #1954

2017-08-01multi: fix request timer managementBrad Spencer
There are some bugs in how timers are managed for a single easy handle that causes the wrong "next timeout" value to be reported to the application when a new minimum needs to be recomputed and that new minimum should be an existing timer that isn't currently set for the easy handle. When the application drives a set of easy handles via the `curl_multi_socket_action()` API (for example), it gets told to wait the wrong amount of time before the next call, which causes requests to linger for a long time (or, it is my guess, possibly forever). Bug: https://curl.haxx.se/mail/lib-2017-07/0033.html
2017-07-28timeval: struct curltime is a struct timeval replacementDaniel Stenberg
... to make all libcurl internals able to use the same data types for the struct members. The timeval struct differs subtly on several platforms so it makes it cumbersome to use everywhere. Ref: #1652 Closes #1693
2017-07-27multi: mention integer overflow risk if using > 500 million socketsDaniel Stenberg
Reported-by: ovidiu-benea@users.noreply.github.com Closes #1675 Closes #1683
2017-06-14http-proxy: do the HTTP CONNECT process entirely non-blockingDaniel Stenberg
Mentioned as a problem since 2007 (8f87c15bdac63) and of course it existed even before that. Closes #1547
2017-06-08expire: remove Curl_expire_latest()Daniel Stenberg
With the introduction of expire IDs and the fact that existing timers can be removed now and thus never expire, the concept with adding a "latest" timer is not working anymore as it risks to not expire at all. So, to be certain the timers actually are in line and will expire, the plain Curl_expire() needs to be used. The _latest() function was added as a sort of shortcut in the past that's quite simply not necessary anymore. Follow-up to 31b39c40cf90 Reported-by: Paul Harris Closes #1555
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
2017-05-12multi: remove leftover debug infof() calls from e9fd794a6Daniel Stenberg
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
2017-04-22multi: clarify condition in curl_multi_waitAlan Jenkins
`if(nfds || extra_nfds) {` is followed by `malloc(nfds * ...)`. If `extra_fs` could be non-zero when `nfds` was zero, then we have `malloc(0)` which is allowed to return `NULL`. But, malloc returning NULL can be confusing. In this code, the next line would treat the NULL as an allocation failure. It turns out, if `nfds` is zero then `extra_nfds` must also be zero. The final value of `nfds` includes `extra_nfds`. So the test for `extra_nfds` is redundant. It can only confuse the reader. Closes #1439
2017-04-22llist: no longer uses mallocDaniel Stenberg
The 'list element' struct now has to be within the data that is being added to the list. Removes 16.6% (tiny) mallocs from a simple HTTP transfer. (96 => 80) Also removed return codes since the llist functions can't fail now. Test 1300 updated accordingly. Closes #1435
2017-04-11Curl_expire_latest: ignore already expired timersDaniel Stenberg
If the existing timer is still in there but has expired, the new timer should be added. Reported-by: Rainer Canavan Bug: https://curl.haxx.se/mail/lib-2017-04/0030.html Closes #1407
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
2017-04-03multi: make curl_multi_wait avoid malloc in the typical caseDaniel Stenberg
When only a few additional file descriptors are used, avoid the malloc. Closes #1377
2017-03-28pause: handle mixed types of data when pausedDaniel Stenberg
When receiving chunked encoded data with trailers, and the write callback returns PAUSE, there might be both body and header to store to resend on unpause. Previously libcurl returned error for that case. Added test case 1540 to verify. Reported-by: Stephen Toub Fixes #1354 Closes #1357
2017-03-27multi: fix MinGW-w64 compiler warningsMarcel Raad
error: conversion to 'long int' from 'time_t {aka long long int}' may alter its value [-Werror=conversion]
2017-03-21multi: fix streamclose() crash in debug modeDaniel Stenberg
The code would refer to the wrong data pointer. Only debug builds do this - for verbosity. Reported-by: zelinchen@users.noreply.github.com Fixes #1329
2017-03-13Improve code readbilitySylvestre Ledru
... by removing the else branch after a return, break or continue. Closes #1310
