ChangeLog

2010-10-07  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* Initial support for Python 3.x throughout the codebase.

2010-09-14  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* OpenSSL/crypto/netscape_spki.c: Fix an off-by-one mistake in the
	  error handling for NetscapeSPKI.verify.  Add additional error
          checking to NetscapeSPKI.sign to handle the case where there is no
          private key.

	* OpenSSL/crypto/x509.c: Fix an overflow bug in the subject_name_hash
	  method of the X509 type which would cause it to return negative
	  values on 32 bit systems.

	* OpenSSL/crypto/x509req.c: Fix an off-by-one mistake in the error
	  handling for X509Req.verify.

	* OpenSSL/ssl/context.c: Fix the error handling in the load_tmp_dh
	  method of the Context type which would cause it to always raise
	  MemoryError, regardless of the actual error (such as a bad file
	  name).

	* OpenSSL/test/: Numerous unit tests added, both for above fixes
	  and for other previously untested code paths.

2010-07-27  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* Re-arrange the repository so that the package can be built and
	  used in-place without requiring installation.

2010-02-27  James Yonan <james@openvpn.net>

	* src/crypto/crypto.c: Added crypto.sign and crypto.verify methods
	  that wrap EVP_Sign and EVP_Verify function families, using code
	  derived from Dave Cridland's PyOpenSSL branch.

	* test/test_crypto.py: Added unit tests for crypto.sign and
	  crypto.verify.

2010-01-27  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/ssl/connection.c, src/util.h: Apply patch from Sandro Tosi to
	  fix misspellings of "compatibility".

2009-11-13  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* Release 0.10

2009-11-07  Žiga Seilnacht, Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/ssl/connection.c, src/ssl/context.c: Add set_client_ca_list,
	  add_client_ca, and get_client_ca_list to Context for manipulating
	  the list of certificate authority names which are sent by servers
	  with the certificate request message.
	* src/util.h: Add ssize-related defines if the version of Python
	  being used does not have them.
	* setup.py: Significant changes to the way Windows builds are done,
	  particularly the way OpenSSL headers and libraries are found (with
	  the new --with-openssl argument to build_ext).

2009-08-27  Rick Dean  <rick@fdd.com>, Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/crypto/pkcs12.c: Add setters to the PKCS12 type for the
	  certificate, private key, ca certificate list, and friendly
	  name, and add a getter for the friendly name.  Also add a method
	  for exporting a PKCS12 object as a string.
	* test/test_crypto.py: Add lots of additional tests for the PKCS12
	  type.
	* doc/pyOpenSSL.tex: Documentation for the new PKCS12 methods.

2009-07-17  Rick Dean  <rick@fdd.com>, Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/crypto/x509ext.c: Add subject and issuer parameters to
	  X509Extension, allowing creation of extensions which require that
	  information.  Fixes LP#322813.

2009-07-16  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* test/util.py: Changed the base TestCase's tearDown to assert that
	  no errors were left in the OpenSSL error queue by the test.
	* src/crypto/crypto.c: Add a private helper in support of the
	  TestCase.tearDown change.
	* src/crypto/x509name.c: Changed X509Name's getattr implementation
	  to clean up the error queue.  Fixes LP#314814.
	* test/util.c: Changed flush_error_queue to avoid a reference
	  counting bug caused by macro expansion.

2009-07-16  Rick Dean  <rick@fdd.com>

	* src/rand.c: Added OpenSSL.rand.bytes to get random bytes directly.
	* src/util.c: Added generic exceptions_from_error_queue to replace
	  the various other implementations of this function.  Also updated
	  the rest of the codebase to use this version instead.

2009-07-05  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* test/util.py, test/test_ssl.py, test/test_crypto.py: Fold the
	  Python 2.3 compatibility TestCase mixin into the TestCase defined
	  in util.py.

2009-07-05  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* test/util.py, test/test_ssl.py, test/test_crypto.py: Stop trying
	  to use Twisted's TestCase even when it's available.  Instead,
	  always use the stdlib TestCase with a few enhancements.

2009-07-04  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* Changed most extension types so that they can be instantiated
	  using the type object rather than a factory function.  The old
	  factory functions are now aliases for the type objects.
	  Fixes LP#312786.

2009-05-27  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* Changed all docstrings in extension modules to be friendlier
	  towards Python programmers.  Fixes LP#312787.

2009-05-27  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/crypto/x509ext.c: Correctly deallocate the new Extension
	  instance when there is an error initializing it and it is not
	  going to be returned.  Resolves LP#368043.

2009-05-11  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* test/test_crypto.py: Use binary mode for the pipe to talk to the
	  external openssl binary.  The data being transported over this
	  pipe is indeed binary, so previously it would often be truncated
	  or otherwise mangled.

	* src/ssl/connection.h, src/ssl/connection.c, test/test_ssl.py:
	  Extend the Connection class with support for in-memory BIOs.  This
	  allows SSL to be run without a real socket, useful for
	  implementing EAP-TLS or using SSL with Windows IO completion
	  ports, for example.  Based heavily on contributions from Rick
	  Dean.

2009-04-25  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* Release 0.9

2009-04-01  Jean-Paul Calderone  <exarkun@twistedmatrix.com>
            Samuele Pedroni  <pedronis@openend.se>

	* src/util.h: Delete the TLS key before trying to set a new value
	  for it in case the current thread identifier is a recycled one (if
	  it is recycled, the key won't be set because there is already a
	  value from the previous thread to have this identifier and to use
	  the pyOpenSSL API).

2009-04-01  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/crypto/crypto.c: Add FILETYPE_TEXT for dumping keys and
	  certificates and certificate signature requests to a text format.

2008-12-31  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/crypto/x509ext.c, test/test_crypto.py: Add the get_short_name
	  method to X509Extension based on patch from Alex Stapleton.

2008-12-31  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/crypto/x509ext.c, test/test_crypto.py: Fix X509Extension so
	  that it is possible to instantiate extensions which use s2i or r2i
	  instead of v2i (an extremely obscure extension implementation
	  detail).

2008-12-30  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* MANIFEST.in, src/crypto/crypto.c, src/crypto/x509.c,
	  src/crypto/x509name.c, src/rand/rand.c, src/ssl/context.c: Changes
	  which eliminate compiler warnings but should not change any
	  behavior.

2008-12-28  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* test/test_ssl.py, src/ssl/ssl.c: Expose DTLS-related constants,
	  OP_NO_QUERY_MTU, OP_COOKIE_EXCHANGE, and OP_NO_TICKET.

2008-12-28  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/ssl/context.c: Add a capath parameter to
	  Context.load_verify_locations to allow Python code to specify
	  either or both arguments to the underlying
	  SSL_CTX_load_verify_locations API.
	* src/ssl/context.c: Add Context.set_default_verify_paths, a wrapper
	  around SSL_CTX_set_default_verify_paths.

2008-12-28  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* test/test_crypto.py, src/crypto/x509req.c: Added get_version and
	  set_version_methods to X509ReqType based on patch from Wouter van
	  Bommel.  Resolves LP#274418.

2008-09-22  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* Release 0.8

2008-10-19  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* tsafe.py: Revert the deprecation of the thread-safe Connection
	  wrapper.  The Connection class should not segfault if used from
	  multiple threads now, but it generally cannot be relied on to
	  produce correct results if used without the thread-safe wrapper.
	* doc/pyOpenSSL.tex: Correct the documentation for the set_passwd_cb
	  callback parameter so that it accurately describes the required
	  signature.

2008-09-22  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* Release 0.8a1

2008-09-21  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/ssl/ssl.h, src/ssl/ssl.c: Add a thread-local storage key
	  which will be used to store and retrieve PyThreadState pointers
	  whenever it is necessary to release or re-acquire the GIL.

	* src/ssl/context.c: Change global_verify_callback so that it
	  unconditionally manipulates the Python threadstate, rather than
	  checking the tstate field which is now always NULL.

2008-04-26  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/ssl/context.c: Change global_passphrase_callback and
	  global_info_callback so that they acquire the GIL before
	  invoking any CPython APIs and do not release it until after they
	  are finished invoking all of them (based heavily on on patch
	  from Dan Williams).
	* src/ssl/crypto.c: Initialize OpenSSL thread support so that it
	  is valid to use OpenSSL APIs from more than one thread (based on
	  patch from Dan Williams).
	* test/test_crypto.py: Add tests for load_privatekey and
	  dump_privatekey when a passphrase or a passphrase callback is
	  supplied.
	* test/test_ssl.py: Add tests for Context.set_passwd_cb and
	  Context.set_info_callback.

2008-04-11  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* Release 0.7

2008-03-26  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/crypto/x509name.c: Add X509Name.get_components

2008-03-25  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/crypto/x509name.c: Add hash and der methods to X509Name.
	* src/crypto/x509.c: Fix a bug in X509.get_notBefore and
	  X509.get_notAfter preventing UTCTIME format timestamps from
	  working.

2008-03-12  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* Fix coding problems in examples/.  Remove keys and certificates
	  and add a note about how to generate new ones.

2008-03-09  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/crypto/x509.c: Add getters and setters for the notBefore and
	  notAfter attributes of X509s.
	* src/crypto/pkey.h, src/crypto/pkey.c, src/crypto/x509req.c,
	  src/crypto/x509.c: Track the initialized and public/private state
	  of EVP_PKEY structures underlying the crypto_PKeyObj type and
	  reject X509Req signature operations on keys not suitable for the
	  task.

2008-03-06  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/crypto/x509name.c: Fix tp_compare so it only returns -1, 0, or
	  1.  This eliminates a RuntimeWarning emitted by Python.
	* src/crypto/x509req.c: Fix reference counting for X509Name returned
	  by X509Req.get_subject.  This removes a segfault when the subject
	  name outlives the request object.
	* src/crypto/x509.c: Change get_serial_number and set_serial_number
	  to accept Python longs.
	* doc/pyOpenSSL.tex: A number of minor corrections.

2008-03-03  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/ssl/connection.c: Expose SSL_get_shutdown and
	  SSL_set_shutdown. (patch from James Knight)
	* src/ssl/ssl.c: Expose SSL_SENT_SHUTDOWN and SSL_RECEIVED_SHUTDOWN.
	  (patch from James Knight)

2008-02-19  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

	* src/ssl/context.c: Expose SSL_CTX_add_extra_chain_cert.
	* src/crypto/x509name.c: Fix memory leaks in __getattr__ and
	  __setattr_ implementations.

	  Ibanescu.

2004-08-09  Martin Sjögren  <msjogren@gmail.com>

	* setup.py src/crypto/: Add support for Netscape SPKI extensions
	  based on a patch from Tollef Fog Heen.
	* src/crypto/crypto.c: Add support for python passphrase callbacks
	  based on a patch from Robert Olson.

2004-08-03  Martin Sjögren  <msjogren@gmail.com>

	  X509.subject_name_hash and X509.digest.

2004-08-02  Martin Sjögren  <msjogren@gmail.com>

	* src/crypto/crypto.c src/ssl/ssl.c: Applied patch from Bastian
	  Kleineidam to fix full names of exceptions.

2002-10-06  Martin Sjögren  <martin@strakt.com>

	* __init__.py: Import tsafe too!

2002-10-05  Martin Sjögren  <martin@strakt.com>

	* src/crypto/x509name.c: Use unicode strings instead of ordinary
	  strings in getattr/setattr. Note that plain ascii strings should
	  still work.

2002-09-17  Martin Sjögren  <martin@strakt.com>

	* Released version 0.5.1.

2002-09-09  Martin Sjögren  <martin@strakt.com>

	* setup.cfg: Fixed build requirements for rpms.

2002-09-07  Martin Sjögren  <martin@strakt.com>

	* src/ssl/connection.c: Fix sendall() method. It segfaulted because
	  it was too generous about giving away the GIL.
	* Added SecureXMLRPCServer example, contributed by Michal Wallace.

2002-09-06  Martin Sjögren  <martin@strakt.com>

	* setup.cfg: Updated the build requirements.
	* src/ssl/connection.c: Fix includes for AIX.

2002-09-04  Anders Hammarquist  <iko@strakt.com>

	* Added type checks in all the other places where we expect
	  specific types of objects passed.

2002-09-04  Martin Sjögren  <martin@strakt.com>

	* src/crypto/crypto.c: Added an explicit type check in the dump_*
	  functions, so that they won't die when e.g. None is passed in.

2002-08-25  Martin Sjögren  <martin@strakt.com>

	* doc/pyOpenSSL.tex: Docs for PKCS12.

2002-08-24  Martin Sjögren  <martin@strakt.com>

	* src/crypto: Added basic PKCS12 support, thanks to Mark Welch
	  <mark@collab.net>

2002-08-16  Martin Sjögren  <martin@strakt.com>

	* D'oh! Fixes for python 1.5 and python 2.1.

2002-08-15  Martin Sjögren  <martin@strakt.com>

	* Version 0.5. Yay!

2002-07-25  Martin Sjögren  <martin@strakt.com>

	* src/ssl/context.c: Added set_options method.
	* src/ssl/ssl.c: Added constants for Context.set_options method.

2002-07-23  Martin Sjögren  <martin@strakt.com>

	* Updated docs
	* src/ssl/connection.c: Changed the get_cipher_list method to actually
	  return a list! WARNING: This change makes the API incompatible with
	  earlier versions!

2002-07-15  Martin Sjögren  <martin@strakt.com>

	* src/ssl/connection.[ch]: Removed the fileno method, it uses the
	  transport object's fileno instead.

2002-07-09  Martin Sjögren  <martin@strakt.com>

	* src/crypto/x509.c src/crypto/x509name.c: Fixed segfault bug where
	  you used an X509Name after its X509 had been destroyed.
	* src/crypto/crypto.[ch] src/crypto/x509req.c src/crypto/x509ext.[ch]:
	  Added X509 Extension support. Thanks to maas-Maarten Zeeman
	  <maas@awanim.com>
	* src/crypto/pkey.c: Added bits() and type() methods.

2002-07-08  Martin Sjögren  <martin@strakt.com>

	* src/ssl/connection.c: Moved the contents of setup_ssl into the
	  constructor, thereby fixing some segfault bugs :)
	* src/ssl/connection.c: Added connect_ex and sendall methods.
	* src/crypto/x509name.c: Cleaned up comparisons and NID lookup.
	  Thank you Maas-Maarten Zeeman <maas@awanim.com>
	* src/rand/rand.c: Fix RAND_screen import.
	* src/crypto/crypto.c src/crypto/pkcs7.[ch]: Added PKCS7 management,
	  courtesy of Maas-Maarten Zeeman <maas@awanim.com>
	* src/crypto/x509req.c: Added verify method.

2002-06-17  Martin Sjögren  <martin@strakt.com>

	* rpm/, setup.cfg: Added improved RPM-building stuff, thanks to
	  Mihai Ibanescu <misa@redhat.com>

2002-06-14  Martin Sjögren  <martin@strakt.com>

	* examples/proxy.py: Example code for using OpenSSL through a proxy
	  contributed by Mihai Ibanescu <misa@redhat.com>
	* Updated installation instruction and added them to the TeX manual.

2002-06-13  Martin Sjögren  <martin@strakt.com>

	* src/ssl/context.c: Changed global_verify_callback so that it uses
	  PyObject_IsTrue instead of requring ints.
	* Added pymemcompat.h to make the memory management uniform and
	  backwards-compatible.
	* src/util.h: Added conditional definition of PyModule_AddObject and
	  PyModule_AddIntConstant
	* src/ssl/connection.c: Socket methods are no longer explicitly
	  wrapped. fileno() is the only method the transport layer object HAS
	  to support, but if you want to use connect, accept or sock_shutdown,
	  then the transport layer object has to supply connect, accept
	  and shutdown respectively.

2002-06-12  Martin Sjögren  <martin@strakt.com>

	* Changed comments to docstrings that are visible in Python.
	* src/ssl/connection.c: Added set_connect_state and set_accept_state
	  methods. Thanks to Mark Welch <mark@collab.net> for this.

2002-06-11  Martin Sjögren  <martin@strakt.com>

	* src/ssl/connection.c: accept and connect now use SSL_set_accept_state
	  and SSL_set_connect_state respectively, instead of SSL_accept and
	  SSL_connect.
	* src/ssl/connection.c: Added want_read and want_write methods.

2002-06-05  Martin Sjögren  <martin@strakt.com>

	* src/ssl/connection.c: Added error messages for windows. The code is
	  copied from Python's socketmodule.c. Ick.
	* src/ssl/connection.c: Changed the parameters to the SysCallError. It
	  always has a tuple (number, string) now, even though the number
	  might not always be useful.

2002-04-05  Martin Sjögren  <md9ms@mdstud.chalmers.se>

	* Worked more on the Debian packaging, hopefully the packages
	  are getting into the main Debian archive soon.

2002-01-10  Martin Sjögren  <martin@strakt.com>

	* Worked some more on the Debian packaging, it's turning out real
	  nice.
	* Changed format on this file, I'm going to try to be a bit more
	  verbose about my changes, and this format makes it easier.

2002-01-08  Martin Sjögren  <martin@strakt.com>

	* Version 0.4.1
	* Added some example code
	* Added the thread safe Connection object in the 'tsafe' submodule
	* New Debian packaging

2001-08-09  Martin Sjögren  <martin@strakt.com>

	* Version 0.4
	* Added a compare function for X509Name structures.
	* Moved the submodules to separate .so files, with tiny C APIs so they
	  can communicate
	* Skeletal OpenSSL/__init__.py
	* Removed the err submodule, use crypto.Error and SSL.Error instead

2001-08-06  Martin Sjögren  <martin@strakt.com>

	* Version 0.3
	* Added more types for dealing with certificates (X509Store, X509Req,
	  PKey)
	* Functionality to load private keys, certificates and certificate
	  requests from memory buffers, and store them too
	* X509 and X509Name objects can now be modified as well, very neat when
	  creating certificates ;)
	* Added SSL_MODE_AUTO_RETRY to smooth things for blocking sockets
	* Added a sock_shutdown() method to the Connection type
	* I don't understand why, but I can't use Py_InitModule() to create
	  submodules in Python 2.0, the interpreter segfaults on the cleanup
	  process when I do. I added a conditional compile on the version
	  number, falling back to my own routine. It would of course be nice to
	  investigate what is happening, but I don't have the time to do so
	* Do INCREF on the type objects before inserting them in the
	  dictionary, so they will never reach refcount 0 (they are, after all,
	  statically allocated)

2001-07-30  Martin Sjögren  <martin@strakt.com>

	* Version 0.2
	* Lots of tweaking and comments in the code
	* Now uses distutils instead of the stupid Setup file
	* Hacked doc/tools/mkhowto, html generation should now work

2001-07-16  Martin Sjögren  <martin@strakt.com>

	* Initial release (0.1, don't expect much from this one :-)
