2017-08-27darwinssl: handle long strings in TLS certsDaniel Stenberg
... as the previous fixed length 128 bytes buffer was sometimes too small. Fixes #1823 Closes #1831 Reported-by: Benjamin Sergeant Assisted-by: Bill Pyne, Ray Satiro, Nick Zitzmann
2017-08-24imap: use defined names for response codesDaniel Stenberg
When working on this code I found the previous setup a bit weird while using proper defines increases readability. Closes #1824
2017-08-23imap: support PREAUTHDaniel Stenberg
It is a defined possible greeting at server startup that means the connection is already authenticated. See https://tools.ietf.org/html/rfc3501#section-7.1.4 Test 846 added to verify. Fixes #1818 Closes #1820
2017-08-23config-tpf: define SIZEOF_LONGJay Satiro
Recent changes that replaced CURL_SIZEOF_LONG in the source with SIZEOF_LONG broke builds that use the premade configuration files and don't have SIZEOF_LONG defined. Bug: https://github.com/curl/curl/issues/1816
2017-08-22config-dos: add missing defines, SIZEOF_* and two othersGisle Vanem
Bug: #1816
2017-08-22makefile.m32: add support for libidn2Viktor Szakats
libidn was replaced with libidn2 last year in configure. Caveat: libidn2 may depend on a list of further libs. These can be manually specified via CURL_LDFLAG_EXTRAS. Closes https://github.com/curl/curl/pull/1815
2017-08-22config-win32: define SIZEOF_LONGViktor Szakats
Recent changes that replaced CURL_SIZEOF_LONG in the source with SIZEOF_LONG broke builds that use the premade configuration files and don't have SIZEOF_LONG defined. Closes https://github.com/curl/curl/pull/1814

2017-08-18http2_recv: return error better on fatal h2 errorsDaniel Stenberg
Ref #1012 Figured-out-by: Tatsuhiro Tsujikawa
2017-08-18http: Don't wait on CONNECT when there is no proxyJan Alexander Steffens (heftig)
Since curl 7.55.0, NetworkManager almost always failed its connectivity check by timeout. I bisected this to 5113ad04 (http-proxy: do the HTTP CONNECT process entirely non-blocking). This patch replaces !Curl_connect_complete with Curl_connect_ongoing, which returns false if the CONNECT state was left uninitialized and lets the connection continue. Closes #1803 Fixes #1804 Also-fixed-by: Gergely Nagy
2017-08-17CURL_SIZEOF_LONG: removed, use only SIZEOF_LONGDaniel Stenberg

... as they're not used externally and internally we check for the sizes already in configure etc. Closes #1767

Fixes #1782 Closes #1787 Reported-by: Peter Lamare
2017-08-17ssh: add the ability to enable compression (for SCP/SFTP)Viktor Szakats
The required low-level logic was already available as part of `libssh2` (via `LIBSSH2_FLAG_COMPRESS` `libssh2_session_flag()`[1] option.) This patch adds the new `libcurl` option `CURLOPT_SSH_COMPRESSION` (boolean) and the new `curl` command-line option `--compressed-ssh` to request this `libssh2` feature. To have compression enabled, it is required that the SSH server supports a (zlib) compatible compression method and that `libssh2` was built with `zlib` support enabled. [1] https://www.libssh2.org/libssh2_session_flag.html Ref: https://github.com/curl/curl/issues/1732 Closes https://github.com/curl/curl/pull/1735
2017-08-16http_proxy: fix build error for CURL_DOES_CONVERSIONSMaksim Stsepanenka
Closes https://github.com/curl/curl/pull/1793
2017-08-16configure: check for __builtin_available() availability (#1788)Nick Zitzmann
This change does two things: 1. It un-breaks the build in Xcode 9.0. (Xcode 9.0 is currently failing trying to compile connectx() in lib/connect.c.) 2. It finally weak-links the connectx() function, and falls back on connect() when run on older operating systems.

2017-08-15cmake: remove dead code for DISABLED_THREADSAFEBenbuck Nason
Closes #1786
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

2017-08-06easy_events: make event data staticDaniel Stenberg
First: this function is only used in debug-builds and not in release/real builds. It is used to drive tests using the event-based API. A pointer to the local struct is passed to CURLMOPT_TIMERDATA, but the CURLMOPT_TIMERFUNCTION calback can in fact be called even after this funtion returns, namely when curl_multi_remove_handle() is called. Reported-by: Brian Carpenter
2017-08-05gssapi: fix memory leak of output token in multi round contextIsaac Boukris
When multiple rounds are needed to establish a security context (usually ntlm), we overwrite old token with a new one without free. Found by proposed gss tests using stub a gss implementation (by valgrind error), though I have confirmed the leak with a real gssapi implementation as well.

2017-08-03CMake: set MSVC warning level to 4Marcel Raad
The MSVC warning level defaults to 3 in CMake. Change it to 4, which is consistent with the Visual Studio and NMake builds. Disable level 4 warning C4127 for the library and additionally C4306 for the test servers to get a clean CURL_WERROR build as that warning is raised in some macros in older Visual Studio versions. Ref: https://github.com/curl/curl/pull/1667#issuecomment-314082794 Closes https://github.com/curl/curl/pull/1711
2017-08-01curl_threads: fix MSVC compiler warningMarcel Raad
Use LongToHandle to convert from long to HANDLE in the Win32 implementation. This should fix the following warning when compiling with MSVC 11 (2012) in 64-bit mode: lib\curl_threads.c(113): warning C4306: 'type cast' : conversion from 'long' to 'HANDLE' of greater size Closes https://github.com/curl/curl/pull/1717
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).
