+Hey Emacs, this is -*- org -*- mode!
+
+* Document all the new stuff.
+* Fix the remaining UI Server problems:
+** VERIFY --silent support.
+** ENCRYPT/DECRYPT/VERIFY/SIGN reset the engine, shouldn't be done with UISERVER?
+
+* IMPORTANT
+** When using descriptor passing, we need to set the fd to blocking before
+ issueing simple commands, because we are mixing synchronous
+ commands into potentially asynchronous operations.
+** Might want to implement nonblock for w32 native backend! Right now,
+ we block reading the next line with assuan.
+
+* Before release:
+** Some gpg tests fail with gpg 1.3.4-cvs (gpg/t-keylist-sig)
+ The test is currently disabled there and in gpg/t-import.
+** When gpg supports it, write binary subpackets directly,
+ and parse SUBPACKET status lines.
+
+* ABI's to break:
+** Old opassuan interface.
+** Implementation: Remove support for old style error codes in
+ conversion.c::_gpgme_map_gnupg_error.
+** gpgme_edit_cb_t: Add "processed" return argument
+ (see edit.c::command_handler).
+** I/O and User Data could be made extensible. But this can be done
+ without breaking the ABI hopefully.
+** All enums should be replaced by ints and simple macros for
+ maximum compatibility.
+** Compatibility interfaces that can be removed in future versions:
+*** gpgme_data_new_from_filepart
+*** gpgme_data_new_from_file
+*** gpgme_data_new_with_read_cb
+*** gpgme_data_rewind
+*** gpgme_op_import_ext
+*** gpgme_get_sig_key
+*** gpgme_get_sig_ulong_attr
+*** gpgme_get_sig_string_attr
+*** GPGME_SIG_STAT_*
+*** gpgme_get_sig_status
+*** gpgme_trust_item_release
+*** gpgme_trust_item_get_string_attr
+*** gpgme_trust_item_get_ulong_attr
+*** gpgme_attr_t
+*** All Gpgme* typedefs.
+
+
+* Thread support:
+** When GNU Pth supports sendmsg/recvmsg, wrap them properly.
+** Without timegm (3) support our ISO time parser is not thread safe.
+ There is a configure time warning, though.
+
+* New features:
+** Flow control for data objects.
+ Currently, gpgme_data_t objects are assumed to be blocking. To
+ break this assumption, we need either (A) a way for an user I/O
+ callback to store the current operation in a continuation that can
+ be resumed later. While the continuation exists, file descriptors
+ associated with this operation must be removed from their
+ respective event loop. or (B) a way for gpgme data objects to be
+ associated with a waitable object, that can be registered with the
+ user event loop. Neither is particularly simple.
+** Extended notation support. When gpg supports arbitrary binary
+ notation data, provide a user interface for that.
+** notification system
+ We need a simple notification system, probably a simple callback
+ with a string and some optional arguments. This is for example
+ required to notify an application of a changed smartcard, The
+ application can then do whatever is required. There are other
+ usages too. This notfication system should be independent of any
+ contextes of course.
+
+ Not sure whether this is still required. GPGME_PROTOCOL_ASSUAN is
+ sufficient for this.
+
+** --learn-code support
+ This might be integrated with import. we still need to work out how
+ to learn a card when gpg and gpgsm have support for smartcards. In
+ GPA we currently invoke gpg directly.
+
+** Might need a stat() for data objects and use it for length param to gpg.
+** Implement support for photo ids.
+** Allow selection of subkeys
+** Allow to return time stamps in ISO format
+ This allows us to handle years later than 2037 properly. With the
+ time_t interface they are all mapped to 2037-12-31
+** New features requested by our dear users, but rejected or left for
+ later consideration:
+*** Allow to export secret keys.
+ Rejected because this is conceptually flawed. Secret keys on a
+ smart card can not be exported, for example.
+ May eventually e supproted with a keywrapping system.
+*** Selecting the key ring, setting the version or comment in output.
+ Rejected because the naive implementation is engine specific, the
+ configuration is part of the engine's configuration or readily
+ worked around in a different way
+*** Selecting the symmetric cipher.
+*** Exchanging keys with key servers.
+
+* Documentation
+** Document validity and trust issues.
+** In gpgme.texi: Register callbacks under the right letter in the index.
+
+* Engines
+** Do not create/destroy engines, but create engine and then reset it.
+ Internally the reset operation still spawns a new engine process,
+ but this can be replaced with a reset later. Also, be very sure to
+ release everything properly at a reset and at an error. Think hard
+ about where to guarantee what (ie, what happens if start fails, are
+ the fds unregistered immediately - i think so?)
+ Note that we need support in gpgsm to set include-certs to default
+ as RESET does not reset it, also for no_encrypt_to and probably
+ other options.
+** Optimize the case where a data object has an underlying fd we can pass
+ directly to the engine. This will be automatic with socket I/O and
+ descriptor passing.
+** Move code common to all engines up from gpg to engine.
+** engine operations can return General Error on unknown protocol
+ (it's an internal error, as select_protocol checks already).
+** When server mode is implemented properly, more care has to be taken to
+ release all resources on error (for example to free assuan_cmd).
+** op_import_keys and op_export_keys have a limit ion the number of keys.
+ This is because we pass them in gpg via the command line and gpgsm
+ via an assuan control line. We should pipe them instead and maybe
+ change gpg/gpgsm to not put them in memory.
+
+* GPG breakage:
+** gpg 1.4.2 lacks error reporting if sign/encrypt with revoked key.
+** gpg 1.4.2 does crappy error reporting (namely none at all) when
+ smart card is missing for sign operation:
+ [GNUPG:] CARDCTRL 4
+ gpg: selecting openpgp failed: ec=6.110
+ gpg: signing failed: general error
+ [GNUPG:] BEGIN_ENCRYPTION 2 10
+ gpg: test: sign+encrypt failed: general error
+** Without agent and with wrong passphrase, gpg 1.4.2 enters into an
+ infinite loop.
+** Use correct argv[0]
+ In rungpg.c:build_argv we use
+ argv[argc] = strdup ("gpg"); /* argv[0] */
+ This should be changed to take the real file name used in account.
+
+
+* Operations
+** Include cert values -2, -1, 0 and 1 should be defined as macros.
+** If an operation failed, make sure that the result functions don't return
+ corrupt partial information. !!!
+ NOTE: The EOF status handler is not called in this case !!!
+** Verify must not fail on NODATA premature if auto-key-retrieval failed.
+ It should not fail silently if it knows there is an error. !!!
+** All operations: Better error reporting. !!
+** Export status handler need much more work. !!!
+** Import should return a useful error when one happened.
+*** Import does not take notice of NODATA status report.
+*** When GPGSM does issue IMPORT_OK status reports, make sure to check for
+ them in tests/gpgs m/t-import.c.
+** Verify can include info about version/algo/class, but currently
+ this is only available for gpg, not gpgsm.
+** Return ENC_TO output in verify result. Again, this is not available
+ for gpgsm.
+** Genkey should return something more useful than General_Error.
+** If possible, use --file-setsize to set the file size for proper progress
+ callback handling. Write data interface for file size.
+** Optimize the file descriptor list, so the number of open fds is
+ always known easily.
+** Encryption: It should be verified that the behaviour for partially untrusted
+ recipients is correct.
+** When GPG issues INV_something for invalid signers, catch them.
+
+* Error Values
+** Map ASSUAN/GpgSM ERR error values in a better way than is done now. !!
+** Some error values should identify the source more correctly (mostly error
+ values derived from status messages).
+** In rungpg.c we need to check the version of the engine
+ This requires a way to get the cached version number from the
+ engine layer.
+
+
+* Tests
+** Write a fake gpg-agent so that we can supply known passphrases to
+ gpgsm and setup the configuration files to use the agent. Without
+ this we are testing a currently running gpg-agent which is not a
+ clever idea. !
+** t-data
+*** Test gpgme_data_release_and_get_mem.
+*** Test gpgme_data_seek for invalid types.
+** t-keylist
+ Write a test for ext_keylist.
+** Test reading key signatures.
+
+* Debug
+** Tracepoints should be added at: Every public interface enter/leave,
+ before and in every callback, at major decision points, at every
+ internal data point which might easily be observed by the outside
+ (system handles). We also trace handles and I/O support threads in
+ the w32 implementation because that's fragile code.
+ Files left to do:
+ data-fd.c data-mem.c data-stream.c data-user.c debug.c rungpg.c
+ engine.c engine-gpgsm.c funopen.c w32-glib-io.c wait.c
+ wait-global.c wait-private.c wait-user.c op-support.c decrypt.c
+ decrypt-verify.c delete.c edit.c encrypt.c encrypt-sign.c export.c
+ genkey.c import.c key.c keylist.c passphrase.c progress.c signers.c
+ sig-notation.c trust-item.c trustlist.c verify.c
+** Handle malloc and vasprintf errors. But decide first if they should be
+ ignored (and logged with 255?!), or really be assertions. !
+
+* Build suite
+** Make sure everything is cleaned correctly (esp. test area).
+** Enable AC_CONFIG_MACRO_DIR and bump up autoconf version requirement.
+ (To fix "./autogen.sh; ./configure --enable-maintainer-mode; touch
+ configure.ac; make"). Currently worked around with ACLOCAL_AMFLAGS???
+
+* Error checking
+** engine-gpgsm, with-validation
+ Add error checking some time after releasing a new gpgsm.
