I added three new public error codes, and then modified the return
codes we use in the transport layer to use the generic error codes
so that there won't be any risk of internal confusions due to
different error code sets.
know that when this define exists, the API exists. And the version number can
be used for run-time checks. 1.1.1 is not likely to be the release version as
I think we'll go with 1.2 instead but 1.1.1 OR LATER should still work.
application can get a pointer back to the internal representation of the host
it just added. Useful for example when the app wants to add a host, and then
convert that exact same host to a line for storing in a known host file.
'store' can also be set to NULL to simple not care.
host so we now only return pointers to structs instead of having the app
allocate a full struct
I moved the private struct definition into knownhosts.c instead of exposing it
wider in libssh2_priv.h
I thus modified the proto for two functions that previously used 'struct
libssh2_knownhost *' to receive data.
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.
pains in apps relying on it, but it is broken by design and we should not
rely on it at all. Go for the LIBSSH2_VERSION_* defines instead if you need
to check for versions.
the making of the release archive.
Added 'maketgz' as a script to build release archives with, including automated
snapshots or whatever. It updates the defines in include/libssh2.h.
configure now extracts the version number from the include/libssh2.h header in
the source tree instead of using it fixed set in the script (to remove the
need for regenerating the configure script when we run maketgz).
Makefile.am now has a dist-hook that puts ".dist" files in the release tree
instead of the file without the .dist extension, so that we can easily add
modified files in release archives. Like maketgz.
calling functions to support that with the following API notes:
* libssh2_publickey_shutdown(), libssh2_session_free() changed
to return an "int" to allow signaling of LIBSSH2_ERROR_EAGAIN.
* libssh2_scp_recv(), libssh2_scp_send_ex() and libssh2_sftp_init()
will loop in on libssh2_channel_free() when there is an error.
It is not possible to return LIBSSH2_ERROR_EAGAIN in this condition
in these 3 functions and not lose the original error code.
all the way up to the user interface. All code modules bug sftp.c have
been completed.
Functions that return an "int", or similar return LIBSSH2CHANNEL_EAGAIN to
indicate some part of the call would block, in non-blocking mode.
Functions that return a structure, like "LIBSSH2_CHANNEL *", return NULL
and set the libssh2 error. The error can be obtained with either
libssh2_session_last_error() or libssh2_session_last_errno(). Either of
these will return the error code of LIBSSH2_ERROR_EAGAIN if the
call would block, in non-blocking mode.
The current state of a function and some variable are keep in the
structures so that on the next call the operation that would block can
be retried again with the same data.
the recent commits converted the tabs to 4 spaces, which matched the
initial indent size. Other commits converted the tabs to 8 spaces, this
didn't match.
All the code has been converted to 4 space indents. No changes to line
lengths or actual code was performed. This is in preperation to my up
coming non-blocking work so my commits should only be code changes and
line lengths in the code I am working on.
