2019-02-26strerror: make the strerror function use local buffersDaniel Stenberg
Instead of using a fixed 256 byte buffer in the connectdata struct. In my build, this reduces the size of the connectdata struct by 11.8%, from 2160 to 1904 bytes with no functionality or performance loss. This also fixes a bug in schannel's Curl_verify_certificate where it called Curl_sspi_strerror when it should have called Curl_strerror for string from GetLastError. the only effect would have been no text or the wrong text being shown for the error.

2019-02-24multi: call multi_done on connect timeoutsDaniel Stenberg
Failing to do so would make the CURLINFO_TOTAL_TIME timeout to not get updated correctly and could end up getting reported to the application completely wrong (way too small). Reported-by: accountantM on github Fixes #3602 Closes #3605
2019-02-23examples: remove recursive calls to curl_multi_socket_actionDaniel Stenberg
From within the timer callbacks. Recursive is problematic for several reasons. They should still work, but this way the examples and the documentation becomes simpler. I don't think we need to encourage recursive calls. Discussed in #3537 Closes #3601

2019-02-22url: change conn shutdown order to unlink data as last stepJay Satiro
- Split off connection shutdown procedure from Curl_disconnect into new function conn_shutdown. - Change the shutdown procedure to close the sockets before disassociating the transfer. Prior to this change the sockets were closed after disassociating the transfer so SOCKETFUNCTION wasn't called since the transfer was already disassociated. That likely came about from recent work started in Jan 2019 (#3442) to separate transfers from connections.

2019-02-20curl: remove MANUAL from -M outputDaniel Stenberg
... and remove it from the dist tarball. It has served its time, it barely gets updated anymore and "everything curl" is now convering all this document once tried to include, and does it more and better. In the compressed scenario, this removes ~15K data from the binary, which is 25% of the -M output. It remains in the git repo for now for as long as the web site builds a page using that as source. It renders poorly on the site (especially for mobile users) so its not even good there. Closes #3587
2019-02-20http2: verify :athority in push promise requestsDaniel Stenberg
RFC 7540 says we should verify that the push is for an "authoritative" server. We make sure of this by only allowing push with an :athority header that matches the host that was asked for in the URL.

2019-02-20singlesocket: fix the 'sincebefore' placementDaniel Stenberg

2019-02-19http: make adding a blank header thread-safeDaniel Stenberg
Previously the function would edit the provided header in-place when a semicolon is used to signify an empty header. This made it impossible to use the same set of custom headers in multiple threads simultaneously. This approach now makes a local copy when it needs to edit the string.

2019-02-18easy: fix win32 init to work without CURL_GLOBAL_WIN32Jay Satiro
- Change the behavior of win32_init so that the required initialization procedures are not affected by CURL_GLOBAL_WIN32 flag. libcurl via curl_global_init supports initializing for win32 with an optional flag CURL_GLOBAL_WIN32, which if omitted was meant to stop Winsock initialization. It did so internally by skipping win32_init() when that flag was set. Since then win32_init() has been expanded to include required initialization routines that are separate from Winsock and therefore must be called in all cases. This commit fixes it so that CURL_GLOBAL_WIN32 only controls the optional win32 initialization (which is Winsock initialization, according to our doc). The only users affected by this change are those that don't pass CURL_GLOBAL_WIN32 to curl_global_init. For them this commit removes the risk of a potential crash.

2019-02-14connection_check: restore original conn->data after the checkJay Satiro
- Save the original conn->data before it's changed to the specified data transfer for the connection check and then restore it afterwards. This is a follow-up to 38d8e1b 2019-02-11. History: It was discovered a month ago that before checking whether to extract a dead connection that that connection should be associated with a "live" transfer for the check (ie original conn->data ignored and set to the passed in data). A fix was landed in 54b201b which did that and also cleared conn->data after the check. The original conn->data was not restored, so presumably it was thought that a valid conn->data was no longer needed. Several days later it was discovered that a valid conn->data was needed after the check and follow-up fix was landed in bbae24c which partially reverted the original fix and attempted to limit the scope of when conn->data was changed to only when pruning dead connections. In that case conn->data was not cleared and the original conn->data not restored. A month later it was discovered that the original fix was somewhat correct; a "live" transfer is needed for the check in all cases because original conn->data could be null which could cause a bad deref at arbitrary points in the check. A fix was landed in 38d8e1b which expanded the scope to all cases. conn->data was not cleared and the original conn->data not restored. A day later it was discovered that not restoring the original conn->data may lead to busy loops in applications that use the event interface, and given this observation it's a pretty safe assumption that there is some code path that still needs the original conn->data. This commit is the follow-up fix for that, it restores the original conn->data after the connection check.

2019-02-14transfer.c: do not compute length of undefined hex buffer.Patrick Monnerat
On non-ascii platforms, the chunked hex header was measured for char code conversion length, even for chunked trailers that do not have an hex header. In addition, the efective length is already known: use it. Since the hex length can be zero, only convert if needed. Reported by valgrind.
