INVALID_SOCKET is a special value in Windows representing a
non-valid socket identifier. We were #defining this to -1 on
non-Windows platforms, causing unneccessary namespace pollution.
Let's have our own identifier instead.
Thanks to Matt Lawson for pointing this out.
Some SFTP servers send SFTP packets larger than 40000. Since the limit
is only present to avoid insane sizes anyway, we can easily bump it.
The define was formerly in the public header libssh2_sftp.h but served
no external purpose and was moved into the source dir.
Bug: http://www.libssh2.org/mail/libssh2-devel-archive-2011-11/0004.shtml
Reported by: Michael Harris
When cross compiling to Windows, libssh2.h include Windows header files
with upper case filenames : BaseTsd.h and WinSock2.h.
These files have lowercase names with mingw-w64 (iirc, it's the same with
mingw). And as on Windows, being lowercase or uppercase does not matter.
As discussed on the mailing list, it was wrong for win64 and using the
VC-provided type is the safest approach instead of second- guessing
which one it should be.
We now allow libssh2_session_flag() to enable compression with a new
flag and I added documentation for the previous LIBSSH2_FLAG_SIGPIPE
flag which I wasn't really aware of!
The function libssh2_session_startup() is now considered deprecated due
to the portability issue with the socket argument.
libssh2_session_handshake() is the name of the replacement.
No idea why we had this ifdef at all but MSVC, MingW32, Watcom
and Borland all have no sys/uio.h header; so if there's another
Win32 compiler which needs it then it should be added explicitely
instead of this negative list.
The condition around the ssize_t typedef depended on both LIBSSH2_WIN32
*and* _MSC_VER being defined when it should be enough to depend on
_MSC_VER only. It also makes it nicer so libssh2-using code builds fine
without having custom defines.
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.
OpenSSH has ways to add hosts to the knownhosts file that include
a specific port number which makes the key associated with only
that specific host+port pair. libssh2 previously did not support
this, and I was forced to add a new function to the API to
properly expose this ability to applications:
libssh2_knownhost_checkp()
To *add* such hosts to the knownhosts file, you make sure to pass
on the host name in that manner to the libssh2_knownhost_addc()
function.
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.
Comments in known_hosts file were not handle properly. They were parsed as
part of the key causing key matching to return a mismatch if the entry had a
comment. This adds a new API function that takes an optional comment and
changes libssh2_knownhost_readline to parse the comment as pass it to the
new function.
Fixes#164.
