2020-03-15transfer: cap retries of "dead connections" to 5Daniel Stenberg
When libcurl retries a connection due to it being "seemingly dead" or by REFUSED_STREAM, it will now only do it up five times before giving up, to avoid never-ending loops. Reported-by: Dima Tisnek Bug: https://curl.haxx.se/mail/lib-2020-03/0044.html Closes #5074

2020-03-15connect: happy eyeballs cleanupDaniel Stenberg
Make sure each separate index in connn->tempaddr[] is used for a fixed family (and only that family) during the connection process. If family one takes a long time and family two fails immediately, the previous logic could misbehave and retry the same family two address repeatedly.

2020-03-14easy: Fix curl_easy_duphandle for builds missing IPv6 that use c-aresJay Satiro
- Ignore CURLE_NOT_BUILT_IN errors returned by c-ares functions in curl_easy_duphandle. Prior to this change if c-ares was used as the resolver backend and either it was too old or libcurl was built without IPv6 support then some of our resolver functions could return CURLE_NOT_BUILT_IN to curl_easy_duphandle causing it to fail. Caused by c8f086b which shipped in 7.69.1. Reported-by: Karl Chen Fixes https://github.com/curl/curl/issues/5097 Closes https://github.com/curl/curl/pull/5100

2020-03-07mime: fix the binary encoder to handle large data properlyPatrick Monnerat
New test 666 checks this is effective. As upload buffer size is significant in this kind of tests, shorten it in similar test 652. Fixes #4860 Closes #4833 Reported-by: RuurdBeerstra on github
2020-03-07mime: do not perform more than one read in a rowPatrick Monnerat
Input buffer filling may delay the data sending if data reads are slow. To overcome this problem, file and callback data reads do not accumulate in buffer anymore. All other data (memory data and mime framing) are considered as fast and still concatenated in buffer. As this may highly impact performance in terms of data overhead, an early end of part data check is added to spare a read call. When encoding a part's data, an encoder may require more bytes than made available by a single read. In this case, the above rule does not apply and reads are performed until the encoder is able to deliver some data. Tests 643, 644, 645, 650 and 654 have been adapted to the output data changes, with test data size reduced to avoid the boredom of long lists of 1-byte chunks in verification data. New test 667 checks mimepost using single-byte read callback with encoder. New test 668 checks the end of part data early detection. Fixes #4826 Reported-by: MrdUkk on github
2020-03-07mime: latch last read callback status.Patrick Monnerat
In case a read callback returns a status (pause, abort, eof, error) instead of a byte count, drain the bytes read so far but remember this status for further processing. Takes care of not losing data when pausing, and properly resume a paused mime structure when requested. New tests 670-673 check unpausing cases, with easy or multi interface and mime or form api. Fixes #4813 Reported-by: MrdUkk on github

2020-03-06multi: skip EINTR check on wakeup socket if it was closedJay Satiro
- Don't check errno on wakeup socket if sread returned 0 since sread doesn't set errno in that case. This is a follow-up to cf7760a from several days ago which fixed Curl_multi_wait to stop busy looping sread on the non-blocking wakeup socket if it was closed (ie sread returns 0). Due to a logic error it was still possible to busy loop in that case if errno == EINTR. Closes https://github.com/curl/curl/pull/5047
