libssh2 automatically handles this sort of partial write chunking when the channel is set to blocking.

no. see in libssh2-0.8/src/channel.c
LIBSSH2_API int libssh2_channel_write_ex(LIBSSH2_CHANNEL *channel, int stream_id, const char *buf, size_t buflen)

this function only wait for first window frame and send data of it's size, instead of buflen.

    if (buflen > channel->local.window_size) {
        buflen = channel->local.window_size;
    }
    if (buflen > channel->local.packet_size) {
        buflen = channel->local.packet_size;
    }

Ah, I see what you're talking about now.

I'm actually going to fix this in libssh2_channel_write so that blocking write really does mean blocking write.

Thanks for your persistence.
