2017-08-28vtls: remove obsolete declarations of SSL backend functionalityJohannes Schindelin
These functions are all available via the Curl_ssl struct now, no need to declare them separately anymore. As the global declarations are removed, the corresponding function definitions are marked as file-local. The only two exceptions here are Curl_mbedtls_shutdown() and Curl_polarssl_shutdown(): only the declarations were removed, there are no function definitions to mark file-local. Please note that Curl_nss_force_init() is *still* declared globally, as the only SSL backend-specific function, because it was introduced specifically for the use case where cURL was compiled with `--without-ssl --with-nss`. For details, see f3b77e561 (http_ntlm: add support for NSS, 2010-06-27). Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28schannel: reorder functions topologicallyJohannes Schindelin
The _shutdown() function calls the _session_free() function; While this is not a problem now (because schannel.h declares both functions), a patch looming in the immediate future with make all of these functions file-local. So let's just move the _session_free() function's definition before it is called. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28axtls: reorder functions topologicallyJohannes Schindelin
The connect_finish() function (like many other functions after it) calls the Curl_axtls_close() function; While this is not a problem now (because axtls.h declares the latter function), a patch looming in the immediate future with make all of these functions file-local. So let's just move the Curl_axtls_close() function's definition before it is called. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: move the SUPPORT_HTTPS_PROXY flag into the Curl_ssl structJohannes Schindelin
That will allow us to choose the SSL backend at runtime. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: convert the have_curlssl_* constants to runtime flagsJohannes Schindelin
The entire idea of introducing the Curl_ssl struct to describe SSL backends is to prepare for choosing the SSL backend at runtime. To that end, convert all the #ifdef have_curlssl_* style conditionals to use bit flags instead. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: move sha256sum into the Curl_ssl structJohannes Schindelin
The SHA-256 checksumming is also an SSL backend-specific function. Let's include it in the struct declaring the functionality of SSL backends. In contrast to MD5, there is no fall-back code. To indicate this, the respective entries are NULL for those backends that offer no support for SHA-256 checksumming. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: move md5sum into the Curl_ssl structJohannes Schindelin
The MD5 summing is also an SSL backend-specific function. So let's include it, offering the previous fall-back code as a separate function now: Curl_none_md5sum(). To allow for that, the signature had to be changed so that an error could be returned from the implementation (Curl_none_md5sum() can run out of memory). Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: use the Curl_ssl struct to access all SSL backends' functionalityJohannes Schindelin
This is the first step to unify the SSL backend handling. Now all the SSL backend-specific functionality is accessed via a global instance of the Curl_ssl struct. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: declare Curl_ssl structs for every SSL backendJohannes Schindelin
The idea of introducing the Curl_ssl struct was to unify how the SSL backends are declared and called. To this end, we now provide an instance of the Curl_ssl struct for each and every SSL backend. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: introduce a new struct for SSL backendsJohannes Schindelin
This new struct is similar in nature to Curl_handler: it will define the functions and capabilities of all the SSL backends (where Curl_handler defines the functions and capabilities of protocol handlers). Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: make sure every _sha256sum()'s first arg is constJohannes Schindelin
This patch makes the signature of the _sha256sum() functions consistent among the SSL backends, in preparation for unifying the way all SSL backends are accessed. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: make sure all _data_pending() functions return boolJohannes Schindelin
This patch makes the signature of the _data_pending() functions consistent among the SSL backends, in preparation for unifying the way all SSL backends are accessed. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: make sure all _cleanup() functions return voidJohannes Schindelin
This patch makes the signature of the _cleanup() functions consistent among the SSL backends, in preparation for unifying the way all SSL backends are accessed. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: use consistent signature for _random() implementationsJohannes Schindelin
This will make the upcoming multissl backend much easier to implement. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

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.

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.

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.

2017-08-15progress: 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

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.
