Both SFTP and SCP are protocols that need to shut down stuff properly
when the connection is about to get torned down. The primary effect of
not doing this shows up as memory leaks (when using SCP or SFTP with the
multi interface).

This is one of the problems detected by test 582.

As we know how much to send, we can and should stop once we've sent that
much data as it avoids having to rely on other mechanisms to detect the
end.

This is one of the problems detected by test 582.

When using the multi_socket API to do SFTP upload, it is important that
we set a quick expire when leaving the SSH_SFTP_UPLOAD_INIT state as
there's nothing happening on the socket so there's no read or write to
wait for, but the next libssh2 API function needs to be called to get
the ball rolling.

This is one of the problems detected by test 582.

All C and H files now (should) feature the proper project curl source
code header, which includes basic info, a copyright statement and some
basic disclaimers.

Instead of using haxx.se as a fixed magic host name in lots of tests,
this is a first step to move toward the generic example.com host
instead.

... since search engines find what they think is a URL in this, they
hammer www.haxx.se on this port!

This is the modified existing files commit.

CyaSSL (available from git@github.com:cyassl/cyassl.git) has been
added to the SSL abstraction layer.

To test:
1) git CyaSSL sources
2) autoreconf -i
3) ./configure --disable-static
4) make
5) sudo make install
6) autoreconf -i
7) git curl sources (and this patch)
8) ./configure --disable-shared --with-cyassl --without-ssl --enable-debug
9) make
10) normal testing

Please send questions or comments to todd@yassl.com .

Stress that it is for client certificates and then mention that it also
works for all other SSL-based protocols apart from HTTPS and
FTPS. Namely POP3S, IMAPS and SMTPS for now.

Accidentally not included in commit 0e74e1d8

Add test 582 for uploading a file using sftp and the multi interface.

(Patch and test slightly tweaked by Daniel Stenberg)

Initially marked as disabled until it is fixed in the source.

The end-of-file #endif in rawstr.h was not correcly positioned after all
prototypes.

Test 558 was just a subset of 559 which is something that can be
easily added later.

These are for when a test failure makes it impossible to continue
running further tests.

libssh2_knownhost_readfile() returns a negative value on error or
otherwise number of parsed known hosts - this was previously not
documented correctly in the libssh2 man page for the function.

|premature| is used in Curl_http_done.

The stopserver function would append pids to kill and could append them
without separating them with space properly. The result would be a very
large number that by (some implementations of) kill would be interpreted
as a negative number and that process group would be wiped...

Flaw introduced in fc77790b and present in curl-7.21.4.
Bug: https://bugzilla.redhat.com/669702#c16

Extend the docs to clarify that CURLOPT_SSH_KEYFUNCTION is only called
if the known hosts option is also correctly set!

CURLOPT_HTTPAUTH was mentioning CURLOPT_USERPASSWORD instead of
CURLOPT_PASSWORD.

This is not needed anymore as we have unit testing running on it.

Removed the "netrc_debug" keyword replaced with --netrc-file additions.
Removed the debug code from Curl_parsenetrc as it is superseeded by
--netrc-file.

This enables people to specify a path to the netrc file to use.
The new option override --netrc if both are present. However it
does follow --netrc-optional if specified.
