Neil Gierman's patch adds a gettimeofday() function for win32
for the libssh2_trace() functionality. The code originates from
cygwin and was put in the public domain by the author
Danny Smith <dannysmith@users.sourceforge.net>
Steven Van Ingelgem introduces libssh2_socket_t as a generic socket
type to use internally to avoid compiler warnings and mistakes. Also,
the private struct iovec declaration for windows is now made to look
like the POSIX struct does.
Each SFTP file handle is now handled by the "mother-struct"
using the generic linked list functions. The goal is to move
all custom linked list code to use this set of functions.
I also moved the list declarations to the misc.h where they
belong and made misc.h no longer include libssh2_priv.h itself
since now libssh2_priv.h needs misc.h...
In misc.c I added a #if 0'ed _libssh2_list_insert() function
because I ended up writing one, and I believe we may need it here
too once we move over more stuff to use the _libssh2_list* family.
properly after recv() and send() calls (that internally are now known as
_libssh2_recv() and _libssh2_send()) so that the API and more works fine on
windows too!
some tests:
* cut off "_ex" from several internal function names
* corrected some log outputs
* simplified libssh2_channel_read_ex() and made it much faster in the process
* cut out {{{ and }}} comments that were incorrect anyway
* fixed sftp_packet_ask() to return the correct packet by using memcmp() and
not strncmp()
* fixed mkdir()'s wait for packet to use the correct request_id - it
semi-worked previously because strncmp() in sftp_packet_ask() made it
match far too easily.
* took away the polling functionality from sftp_packet_ask() since it wasn't
used
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.
various stuff if libssh2 was built with debug. If built without debug, the
function does nothing.
2 - configure --enable-debug is now enough to build a debug version (including
picky compiler options)
3 - internally, we no longer need/use #ifdef/#endif around all uses of the
_libssh2_debug() function/macro.
The scp.c example is the first application to test this new debug logging.
blocking way. The channel code is now responsible for enabling/disabling
blocking status and to work with it.
I've also modified indenting and fixed compiler warnings at places, and
added a bunch of new examples in example/simple that I've used to verify that
the code still runs like before.
libssh2_channel_{read|write}nb_ex() and libssh2_sftp_{read|write}nb() are the
four new functions that supposedly work non-blocking.
The convience functions pass in the return from strlen() which is "size_t",
usually an "unsigned long". This created the possiblility of passing in
a value that could look negative.
All "int" lengths were converted to "unsigned int". Ideally they should
all become "size_t", but that is a bigger change. This is a good start.
