Hello
I've written two example programs that do SCP and SFTP downloads in a
non-blocking manner, and both of the now run fine here.
There's a few BUTs to this claim, and I'd like to share them with you:
1 - not all functions are or will be non-blocking, as there is a vast amount
of them and fixing all is a large job that isn't possible for me to do
right now. I've so far focused on the main ones used for SCP and SFTP
downloads (libssh2_channel_read and libssh2_sftp_read) and I intend to
work on the upload versions next.
2 - for LOTS of functions we need to change the prototypes to allow them to
return a "EAGAIN" error code (instead of blocking) until they are done and
can return ok. A few examples are libssh2_sftp_init(),
libssh2_sftp_open(), libssh2_scp_recv(). I would really appreciate some
input on how to proceed on that. I figure we should make them all return
an 'int' and have them get handles passed back in a pointer pointer
argument. Or does anyone have any other thoughts on this?
Like before, I'll provide patches on request until I'll be able to commit
this.
