Version 1.2 (August 10, 2009)

Alexander Lamaison tracked down that my previous commit broke SFTP
reads in some aspects. The reversion now gets back to always recv()
until EAGAIN is returned so that the code no longer treats a short
read as an indication that it is "enough for now".

The bad commit in particular had another independent change included,
which is to clear the direction-bits first in the transport read
and write functions, but this reversion does not revert that change.
Clearing those bits first is a good thing.

+Version 1.2 (August 10, 2009)
+-----------------------------
+
+* (August 02 2009) Alexander Lamaison:
+
+ - changed _libssh2_rsa_new_private and _libssh2_rsa_new_private so that they
+   no longer use the OpenSSL functions that take a FILE* argument.  Passing
+   CRT-created objects across a DLL boundary causes crashes on Windows of the
+   DLL and the client aren't linked to the exact same verison of the CRT. Now
+   we pass the keys as strings to avoid this issue.
+
+* (May 29 2009) Daniel Stenberg:
+
+ - Updated the knownhost API and there are now 9 functions, and all of them
+   have man pages. The libssh2.h now defines HAVE_LIBSSH2_KNOWNHOST_API to
+   ease things for applications to check for the correct release before trying
+   to use it.
+
+* (May 23 2009) Daniel Stenberg:
+
+ - Anonymous bug report #2795816 revealed that doing subsequent
+   libssh2_sftp_init() calls on the same session failed.
+
+* (May 20 2009) Daniel Stenberg:
+
+  - made libssh2_sftp_write() properly deal with huge/any sized input buffers.
+
+  - fixed libssh2_channel_write_ex() to return the correct return code, and
+    deal with sending off huge buffers better
+
+* (May 7 2009) Daniel Stenberg:
+
+  - linked list code. I got a bit tired of the fact that we don't have any
+    generic linked-list functions within libssh2 so I wrote up the first embryo
+    for one that I use for this new functionality. The plan would then be to
+    move all existing code that uses linked lists to use this new set.
+
+  - base64 encode. I had to add a base64 encoding function which was missing
+    in the code base so it helps to "bloat" my patch.
+
+  - The knownhost API is currently:
+
+    _init() - init a bundle of known hosts
+    _add()  - add a known host
+    _del()  - delete a known host
+    _free() - free an entire bundle of known hosts
+    _check() - check if a host+key is present in the bundle
+
+    The convenience function:
+
+    _parsefile() - reads a ~/.ssh/known_hosts file and add all entries to the
+                   given bundle
+
+   - there's no docs other than some comments in the code/headers yet
+
+  - the patch includes changes to example/simple/ssh2_exec.c that makes use of
+    a few of these functions. Using that I've verified that the functions in
+    fact can verify my localhost's key agains my ~/.ssh/known_hosts file
+
+* (Apr 30 2009) Daniel Stenberg:
+
+  Markus posted a bug report about a bad 0-return from libssh2_channel_read:
+  http://libssh2.haxx.se/mail/libssh2-devel-archive-2009-04/0076.shtml
+
+  And it was indeed a bad loop that terminated too early due to a receveived
+  close packet.
+
+* (Apr 14 2009) Daniel Stenberg:
+
+  libssh2_poll() and libssh2_poll_channel_read() are now considered and
+  documented deprecated and they will be removed at next soname bump. It also
+  saves us from fixing some rather quirky bugs in libssh2_poll()...
+
+
+Version 1.1 (April 2, 2009)
+---------------------------
+
+- (Mar 28 2009) Daniel Stenberg:
+
+  Jean-Louis Charton found a memory leak in
+  libssh2_userauth_hostbased_fromfile_ex()
+
+- (Mar 25 2009) Daniel Stenberg:
+
+   * Renamed the functions in src/transport.c to be _libssh2_transport_ prefixed
+     and introduced a transport.h header.
+
+   * Fixed the blocking mode to only change behavior not the actual underlying
+     socket mode so we now always work with non-blocking sockets. This also
+     introduces a new rule of thumb in libssh2 code: we don't call the
+     external function calls internally. We use the internal (non-blocking)
+     ones!
+
+   * libssh2_channel_receive_window_adjust2 was added and
+     libssh2_channel_receive_window_adjust is now deprecated
+
+   * Introduced "local" header files with prototypes etc for different parts
+     instead of cramming everything into libssh2_priv.h. channel.h is the
+     first.
+
+- (Mar 19 2009) Daniel Stenberg: based on a patch by "E L" we now use errno
+  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!
+
+- (Mar 17 2009) Simon Josefsson:
+
+  Added a Libtool -export-symbols-regex flag to reduce the number of
+  exported symbols in shared libraries.  Reported by Mikhail Gusarov.
+
+- (Mar 16 2009) Daniel Stenberg:
+
+  I renamed a few man pages to match the exact name of the functions they
+  describe. I also added template versions for the 13 functions that
+  previously lacked man pages. While these don't contain any docs just yet, it
+  will now be easier to add the info as the foundation is there!
+
+- (Mar 15 2009) Daniel Stenberg:
+
+  * libssh2_channel_read_ex() was simplified and enhanced. It now adjusts the
+    window less frequent and uses much larger window that now allows MUCH
+    faster transfers.
+
+  * SCP send/recv now allow file names with whitespaces etc, thanks to a patch
+    by Heiner Steven
+
+- (Mar 13 2009) Daniel Stenberg: Cleanups, that do seem to have boosted SFTP
+  download performance up to 300% in 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
+
+- (Mar 7 2009) Olivier Hervieu pointed out a flaw in the
+  libssh2_channel_x11_req_ex() function that made it produce a crappy random
+  chunk of data. Peter Stuge improved the fix to not do out-of-boundary
+  writes. I (Daniel Stenberg) replaced the snprintf() with a plain sprintf()
+  since the size argument wasn't adding anything anyway.
+
+- (Feb 23 2009) Added libssh2_version()
+
+- (Feb 20 2009) libssh2_channel_direct_tcpip_ex() bug #1902169 fixed, which
+  caused it to fail when called a second time.
+
+- (Feb 12 2009) Romain Bondue extended Markus Moeller fix from Feb 8, based on
+  a previous (uncommitted) patch by Erik Brossler. It improves
+  libssh2_channel_write_ex in blocking situations when the socket is set non-
+  blocking.
+
+- (Feb 8 2009) Markus Moeller fixed a flaw in libssh2_channel_write_ex() that
+  would occur on EAGAIN situations.
+
+Version 1.0 (December 26 2008)
+------------------------------
+
+- (Dec 20 2008) Based on Alexander Lamaison's patch, there's now a new
+  function called libssh2_sftp_tell64() that returns the 64 bit file offset,
+  as the existing libssh2_sftp_tell() only returns a size_t.
+
+- (Dec 18 2008) Markus Moeller fixed the issue also reported by Alexander
+  Lamaison which caused SFTP reads with large buffers to fail.
+
+- Several flaws were fixed that prevented at least SFTP to work reliably
+
+- Vlad Grachov brought the new function called
+  libssh2_session_block_directions() which returns a bitmask for what
+  directions the connection blocks. It is to be used applications that use
+  non-blocking sockets and when a libssh2 function returns
+  LIBSSH2_ERROR_EAGAIN this function can be used to figure out in which
+  direction the socket would block and thus it can wait for the socket to
+  again be ready for communication in that direction before it calls libssh2
+  again.
+
+- Vincent Jaulin brought the new libssh2_channel_request_pty_size_ex()
+  function.
+
+- Carlo Bramini fixed the build for msys+mingw. Bug #1943976.
+
+- Neil Gierman provided improved Visual Studio 2008 code in bug #1946268
+
+- Bug #1862727 fixed libssh2_poll() to work on windows (by defining
+  HAVE_SELECT).
+
+- Based on bug #1815692, we introduce libssh2_sftp_seek64() that allows
+  seeking beyond the 2GB margin even on 32bit machines.
+
+- Based on a patch in bug #1878059 by Steven Ayre libssh2 now parses >2GB file
+  sizes when downloading SCP files.
+
+- Bug #2064371 pointed out that the SSH2 banner may not use dash
+  ('-'). Reported by Bjorn Stenborg.
+
+- Sean Peterson fixed a key re-exchange bug:
+  http://daniel.haxx.se/projects/libssh2/mail/libssh2-devel-archive-2008-06/0002.shtml
+
+- Mike Protts filed the bug report #1908724 that identified and fixed a problem
+  with SFTP stat on files >4GB in size. Previously it used 32bit math only.
+
+- Removed a stderr debug message that was accidentally left in (bug #1863153)
+
+- OpenSSL and libz detection changed to make cross-compiling to Mingw
+  work.  See README for parameters to use if the auto-detection does
+  not work for you.  From Simon Josefsson.
+
+- Simon Josefsson added a self-test that uses libssh2 to connect to a
+  local sshd (only enabled if if OpenSSH is installed).
+
+Version 0.18 (November 11 2007)
+-------------------------------
+
+- Various changes that improve non-blocking operations and prevent stalls.
+  Especially noticable on Windows since libssh2 just didn't work properly
+  non-blocking on Windows before.
+
+- Peter O'Gorman reported how a SCP transfer would hang for him, and it was
+  fairly easy reproducable. One bug was in the transport layer, ignoring to
+  read more data while there was data left even though it couldn't decrypt the
+  data that was left due to it being too little... The other bug was in the
+  channel layer, where the libssh2_channel_receive_window_adjust() function
+  missed to set the state variables at times and thus this function would
+  misbehave on repeated invokes.
+
+- Changed the signature of libssh2_channel_setenv_ex to add const to the
+  "varname" parameter (Dan Fandrich)
+
+- Satish Mittal and David J Sullivan fixed an infinit recv() loop in
+  libssh2_banner_receive()
+

+Of course we would have nothing without the great work by Sara Golemon that
+we're extending and building upon.

 libssh2 - SSH2 library
 ======================
 
-Version 0.3
------------
+libssh2 is a library implementing the SSH2 protocol, available under
+the revised BSD license.
 
-  Fixed libssh2_channel_read_ex().  Packet loop initialized BEFORE transport polled for new packets (should have been after).
+Web site: http://www.libssh2.org/
 
-  Fixed blocking issues in scp_send()/scp_recv().
+Mailing list: http://cool.haxx.se/mailman/listinfo/libssh2-devel
 
-  Fixed degree of indirection in macerror callback.
+Generic installation instructions are in INSTALL.  Some ./configure
+options deserve additional comments:
 
-  Changed packet read mechanism to use a fixed buffer and avoid unnecessary alloc/free calls. (especially while non-block looping)
+	* --enable-crypt-none
 
-  Added channel close callback.
+		The SSH2 Transport allows for unencrypted data
+		transmission using the "none" cipher.  Because this is
+		such a huge security hole, it is typically disabled on
+		SSH2 implementations and is disabled in libssh2 by
+		default as well.
 
-  Added SFTP support (Using its own header file: libssh2_sftp.h)
+		Enabling this option will allow for "none" as a
+		negotiable method, however it still requires that the
+		method be advertized by the remote end and that no
+		more-preferable methods are available.
 
-Version 0.2
------------
+	* --enable-mac-none
 
-  Changed extended data ignorance mechanism:
-    libssh2_channel_ignore_extended_data() changed to libssh2_channel_handle_extended_data()
-    Macro introduced for backward compatability during beta phase.
-    *** THE LIBSSH2_CHANNEL_IGNORE_EXTENDED_DATA() MACRO WILL BE REMOVED PRIOR TO 1.0 RELEASE ***
-    libssh2_channel_handle_extended_data() may be passed one of three "ignore_mode" constants
-      LIBSSH2_CHANNEL_EXTENDED_DATA_NONE       Default behavior, queue ED packets and return them with read_ex
-      LIBSSH2_CHANNEL_EXTENDED_DATA_IGNORE     Equivalent to libssh2_channel_ignore_extended_data()
-                                               IGNORE will implicitly flush the extended data stream(s)
-      LIBSSH2_CHANNEL_EXTENDED_DATA_MERGE      Calls to channel_read() will check both the standard data stream
-                                               and the extended data stream(s) for the first available packet
+		The SSH2 Transport also allows implementations to
+		forego a message authentication code.  While this is
+		less of a security risk than using a "none" cipher, it
+		is still not recommended as disabling MAC hashes
+		removes a layer of security.
 
-  Changed libssh2_session_disconnect_ex() to return an error code when alloc fails
+		Enabling this option will allow for "none" as a
+		negotiable method, however it still requires that the
+		method be advertized by the remote end and that no
+		more-preferable methods are available.
 
-  Added libssh2_channel_flush_ex() and basic macros: ..._flush() ..._flush_stderr()
-    flush_ex accepts either the streamid (0 for standard data, 1 for stderr) or one of the two following constants:
-      LIBSSH2_CHANNEL_FLUSH_ALL                Flush all streams
-      LIBSSH2_CHANNEL_FLUSH_EXTENDED_DATA      Flush all streams EXCEPT the standard data stream
+	* --disable-gex-new
 
-  Added libssh2_session_callback_set() for setting ignore/debug/disconnect/macerror callbacks
+		The diffie-hellman-group-exchange-sha1 (dh-gex) key
+		exchange method originally defined an exchange
+		negotiation using packet type 30 to request a
+		generation pair based on a single target value.  Later
+		refinement of dh-gex provided for range and target
+		values.  By default libssh2 will use the newer range
+		method.
 
-  Added libssh2_session_method_pref() to selectively set methods and method preferences.
+		If you experience trouble connecting to an old SSH
+		server using dh-gex, try this option to fallback on
+		the older more reliable method.
 
-  Added libssh2_session_methods() to determine what methods were negotiated.
+  	* --with-libgcrypt
+  	* --without-libgcrypt
+	* --with-libgcrypt-prefix=DIR
 
-  Added libssh2_session_abstract() for retreiving &session->abstract
+		libssh2 can use the Libgcrypt library
+		(http://www.gnupg.org/) for cryptographic operations.
+		Either Libgcrypt or OpenSSL is required.
 
-  Added libssh2_session_last_error() for retreiving error codes/messages
+		Configure will attempt to locate Libgcrypt
+		automatically.
 
-Version 0.1
------------
+ 		If your installation of Libgcrypt is in another
+		location, specify it using --with-libgcrypt-prefix.
 
-  Initial Release:
-    KEX methods: diffie-hellman-group14-sha1, diffie-hellman-group-exchange-sha1, diffie-hellman-group1-sha1
-    Hostkey methods: ssh-rsa, ssh-dss
-    Cipher methods: aes256-cbc, rijndael-cbc@lysator.liu.se, aes192-cbc, aes128-cbc, blowfish-cbc, arcfour, cast128-cbc, 3des-cbc, none*
-    Compression methods: zlib, none
-    MAC methods: hmac-sha1, hmac-sha1-96, hmac-ripemd160, hmac-ripemd160@openssh.com none*
-    *Cipher/MAC "none" is disabled by default for security purposes,
-     Use --enable-crypt-none and/or --enable-mac-none with ./configure to enable
+	* --with-openssl
+	* --without-openssl
+	* --with-libssl-prefix=[DIR]
+
+		libssh2 can use the OpenSSL library
+		(http://www.openssl.org) for cryptographic operations.
+		Either Libgcrypt or OpenSSL is required.
+
+		Configure will attempt to locate OpenSSL in the
+		default location.
+
+		If your installation of OpenSSL is in another
+		location, specify it using --with-libssl-prefix.
+
+	* --with-libz
+	* --without-libz
+	* --with-libz-prefix=[DIR]
+
+		If present, libssh2 will attempt to use the zlib
+		(http://www.zlib.org) for payload compression, however
+		zlib is not required.
+
+		If your installation of Libz is in another location,
+		specify it using --with-libz-prefix.
+
+	* --enable-debug
+
+		Will make the build use more pedantic and strict compiler
+		options as well as enable the libssh2_trace() function (for
+		showing debug traces).

-* More Crypt Methods
-* hmac-md5, hmac-md5-96
-* Review callbacks
+Things TODO
+===========
+
+* make sure the windowing code adapts better to slow situations so that it
+  doesn't then use as much memory as today
+
+* Introduce a 'libssh2_socket_t' type for sockets in internal code
+
+* Provide a libssh2_scp_send() API for files larger than 4GB (32bit size)
+
+* Convert the linked list code used all over to use the (new) generic linked
+  list code. See the _libssh2_list_*() functions in src/misc.c
+
+* Add more info to the man pages.
+
+* Decrease the number of mallocs. Everywhere.
+
+* Use SO_NOSIGPIPE for Mac OS/BSD systems where MSG_NOSIGNAL doesn't exist/work
+
+* Extend the test suite to actually test lots of aspects of libssh2
+
+* Fix all compiler warnings (some can't be done without API changes)
+
+At next SONAME bump
+===================
+
+* stop using #defined macros as part of the official API. The macros should
+  either be turned into real functions or discarded from the API.
+
+* fix the parts of the API where object pointers and function pointers are

+This function is deprecated in 1.1. Use

+
+Adjust the receive window for a channel by adjustment bytes. If the amount to

+made to return a 'long' which may not be 32 bit on all platforms.

+In 1.0 and earlier, this function returns LIBSSH2_ERROR_EAGAIN for
+non-blocking channels where it would otherwise block. However, that is a
+negative number and this function only returns an unsigned value and this then
+leads to a very strange value being returned.
