Net::SSH2, the Perl wrapping module for libssh2 implements several features*
on top of libssh2 that can fail and so need some mechanism to report the error
condition to the user.
Until now, besides the error state maintained internally by libssh2, another
error state was maintained at the Perl level for every session object and then
additional logic was used to merge both error states. That is a maintenance
nighmare, and actually there is no way to do it correctly and consistently.
In order to allow the high level language to add new features to the library
but still rely in its error reporting features the new function
libssh2_session_set_last_error (that just exposses _libssh2_error_flags) is
introduced.
*) For instance, connecting to a remote SSH service giving the hostname and
port.

Despite we announced the CMake support in libssh2-1.6.0 release notes,
the files required by the CMake build system were not included in the
release tarballs. Hence, the only way to use CMake for build was the
upstream git repository.
This commit makes CMake actually supported in the release tarballs.
The new libssh2_sftp_fsync API causes data and metadata in the
currently open file to be committed to disk at the server.
This is an OpenSSH extension to the SFTP protocol. See:
https://bugzilla.mindrot.org/show_bug.cgi?id=1798
Someone on IRC pointed out that we don't have these documented so I
wrote up a first set based on the information in the wiki:
http://trac.libssh2.org/wiki/KeepAlive
Split off libssh2_sftp_seek64 from the libssh2_sftp_seek man page, and
mentioned that we consider the latter deprecated. Also added a mention
about the dangers of doing seek during writing or reading.
I found an undocumented public function and we can't have it like
that. The description here is incomplete, but should serve as a template
to allow filling in...
As the long-term goal is to get rid of the extensive set of
macros from the API we can just as well start small by not adding
new macros when we add new functions. Therefore we let the
function be libssh2_sftp_statvfs() plainly without using an _ex
suffix.
I also made it use size_t instead of unsigned int for the string
length as that too is a long-term goal for the API.
The previously existing libssh2_scp_send_ex() function has no way
to send files that are larger than 'size_t' which on 32bit
systems mean 4GB. This new API uses a libssh2_int64_t type and
should thus on most modern systems be able to send enormous
files.
all #defined macros in the public headers are considered to be part
of the API and I've generated individual man pages for each of them
to A) make it easier to figure out what each function/macro actually
is for so that automated lookups work better and for B) make sure we
have all public functions document (both macros and functions) to
make it easier for us to work away from all the macros in a future
release.
and introduced a transport.h header.
* Fixed the blocking mode to only change behavior not the actual underlying
socket mode so we now always work with non-blocking sockets. This also
introduces a new rule of thumb in libssh2 code: we don't call the
external function calls internally. We use the internal (non-blocking)
ones!
* libssh2_channel_receive_window_adjust2 was added and
libssh2_channel_receive_window_adjust is now deprecated
* Introduced "local" header files with prototypes etc for different parts
instead of cramming everything into libssh2_priv.h. channel.h is the
first.
libssh2_session_block_directions() which returns a bitmask for what
directions the connection blocks. It is to be used applications that use
non-blocking sockets and when a libssh2 function returns
LIBSSH2_ERROR_EAGAIN this function can be used to figure out in which
direction the socket would block and thus it can wait for the socket to
again be ready for communication in that direction before it calls libssh2
again.
