We reserve ^libssh2_ for public symbols and we use _libssh2 as
prefix for internal ones. I fixed the intendation of all these
edits with emacs afterwards, which then changed it slightly more
than just _libssh2_error() expressions but I didn't see any
obvious problems.
This function no longer has any special purpose code for the
single entry case, as it was pointless.
The previous code would overflow the buffers with an off-by-one
in case the file name or longentry data fields received from the
server were exactly as long as the buffer provided to
libssh2_sftp_readdir_ex.
We now make sure that libssh2_sftp_readdir_ex() ALWAYS zero
terminate the buffers it fills in.
The function no longer calls the libssh2_* function again, but
properly uses the internal sftp_* instead.
When we ignore the EAGAIN from the transport layer within channel_write, we
now drain the outgoing transport layer buffer so that remainders in that
won't cause any problems in the next invoke of _libssh2_transport_write()
When sending data in a loop, we must not return EAGAIN if we
managed to send data in an earlier round. This was reported in
bug #126 => http://libssh2.stuge.se/ticket/126
When _libssh2_channel_write() is asked to send off 9 bytes, the
code needs to deal with the situation where less than 9 bytes
were sent off and prepare to send the remaining piece at a later
time.
As reported in bug report #166http://libssh2.stuge.se/ticket/166
by 'ptjm', the maximum window size must be less crazy for libssh2
to do better with more server implementations. I did not do any
testing to see how this changes raw SCP performance, but the
maximum window size is still almost 4MB. This also has the upside
that libssh2 will use less memory.
commit 7317edab61 cleared the outbound
blocking bit when send_existing() returned PACKET_NONE and *ret=0, as
opposed to before even calling send_existing(), but because *ret=1 when
sending parts 2..n of an existing packet, the bit would only be cleared
when calling libssh2_transport_write() for a new packet.
Clear the direction flag after the final part of a packet has been sent.
Suyog Jadhav pointed out that when receiving a window adjust to
a channel not found, the code would reference a NULL pointer.
Now it will instead output a message about that fact.
Comments in known_hosts file were not handle properly. They were parsed as
part of the key causing key matching to return a mismatch if the entry had a
comment. This adds a new API function that takes an optional comment and
changes libssh2_knownhost_readline to parse the comment as pass it to the
new function.
Fixes#164.
