* The following low level packet routines now fully support non-blocking:
libssh2_sftp_packet_read()
libssh2_sftp_packet_ask()
libssh2_sftp_packet_require()
libssh2_sftp_packet_requirev()
* libssh2_sftp_readdirnb() functions completely in non-blocking mode
* The rest of the routines which call the libssh2_sftp_packet_* routine
loop on a return code of PACKET_EAGAIN. This maintains the current
functionality until they fully support non-blocking
* The state of all function are labeled with either NB-SAFE or NB-UNSAFE,
for those that are know. NB-UNSAFE?? for those that haven't been
examined.
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.
include/ into the src/ directory. The include/ dir is now strictly for public
headers.
Also, I removed the special win32 source package creation target in the
makefile and I modified the contact email address in configure.in to point out
the libssh2-devel list.
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.
