* src/key.c (gpgme_key_unref): Always free address if set.
(_gpgme_key_append_name): Remove memory optimization for address.

--
The check if address is not allocated would now be more complicated
then just comparing it to email because email is set to address
also when an email was not parsed from the user id.

a28d31fdb6 core: Improve mailbox only uid handling
* src/key.c (_gpgme_key_append_name): Set email and remove name
for uid only keys.

--
If we have a name and no email but the name can be parsed as
an address we now treat the address as email and remove the name.

This fixes downstream users that rely on email to show email
addresses and don't expilicity handle this case.

E.g. A userid foo@example.com was:
uid->name = "foo@example.com"
uid->email = ""
uid->address = "foo@example.com"

It is now:
uid->name = ""
uid->email = "foo@example.com"
uid->address = "foo@example.com"

gpg(1) documents session key export as useful for key escrow, and is
rightly dubious of that use case.  However, session key export is also
useful in other use cases.  Two examples from MUA development (where
this functionality would be specifically useful to me right now):

 * If the MUA stores a local copy of the session key upon decrypting
   the message, it can re-decrypt the message without expensive
   asymmetric operations.  When rendering a thread with dozens of
   encrypted messages, this can represent a significant speedup.

 * A user may have expired encryption-capable secret key material,
   along with many messages encrypted to that material.  If she stores
   the session keys for those messages she wants to keep, she can
   destroy her secret key material and make any messages she has
   deleted completely unrecoverable, even to an attacker who gets her
   remaining secret keys in the future.

This patchset makes a two specific implementation decisions that could
have gone in different ways.  I welcome feedback on preferred outcomes.

 0) session key representation: we currently represent the session key
    as an opaque textual string, rather than trying to provide any
    sort of in-memory structure.  While it wouldn't be hard to parse
    the data produced by gpg's --export-session-key, I chose to use
    the opaque string rather than lock in a particular data format.

 1) API/ABI: i've added a member to gpgme_op_decrypt_result_t.  This
    has the potential to cause an out-of-bound memory access if
    someone uses code compiled against the newer verision, but linked
    at runtime against an older version.  I've attempted to limit that
    risk by documenting that users must verify
    gpgme_get_export_session_keys() before accessing this new struct
    member -- this means that code expecting this capability will
    require the symbol at link-time, and will refuse to link against
    older versions.

    Another approach to solving this problem would be to avoid
    modifying gpgme_op_decrypt_result_t, and to introduce instead a
    new function gpgme_op_session_key(), which could be called in the
    same places as gpgme_op_decrypt_result().  Depending on the
    representation of the session key, this might introduce new
    memory-management burdens on the user of the library, and the
    session key is certainly part of a decryption result, so it seemed
    simpler to go with what i have here.

If anyone has strong preferences that these choices should be solved
in a different way, i'm happy to hear them.

Additionally, I note that i'm also still pretty unclear about how the
"UI Server" fits into this whole ecosystem. In particular, I don't
know whether it's kosher to just add an --export-session-key flag to
the DECRYPT operation without actually having implemented it anywhere,
but i don't see where i would actually implement it either :/

If this patch (or some variant) is adopted, i will supply another
patch that permits offering a session key during decryption (e.g. "gpg
--override-session-key"), but I wanted to get these implementation
choices ironed out first.

On the concern of adding a new field to a structure: It may not be
clearly documented but we don't expect that a user ever allocates such
a structure - those result structure may only be created bu gpgme and
are read-only for the user.  Adding a new member constitutes a
compatible ABI change and thus an older SO may not be used by code
compiled with a header for the newer API.  Unless someone tinkers with
the build system, this should never happen.  We have added new fields
to result structure may times and I can't remember any problems.

core: Non-zero values should set _armor, _textmode, and _online.
* src/gpgme.c (gpgme_set_armor, gpgme_set_textmode,
gpgme_set_offline): Ensure that non-zero values actually set the
appropriate internal bit.

--

The documentation for these functions says things like "disabled if
YES is zero, and enabled otherwise", where YES is an integer.
However, if you pass an even integer, it will be aliased back to 0
because the context member variables are declared as single bits.

This should make the implementation match the documentation.

core: Use better error code when using select with a too high fd.
* src/posix-io.c (_gpgme_io_select): Return EMFILE instead of EBADF.
--

Also EBADF seem more correct, EMFILE (Too man open files) gives
a clearer message to the user that there are somehow too many files
open.  The problem can be exhibited by running lots of threads,

We should eventually move to poll but that would be a large change and
so we better fix it with the planned migration of the I/O subsystem to
libgpgrt (currently known as libgpg-error).

--
Using gpgrt locks instead of pthread locks removes
the neccessity to link pthread directly to gpgme and
have a different, thread safe flavor of gpgme. Now
gpgme is thread-safe if the conditions mentioned
in the doc are met.

As the cpp bindings linked against libgpgme
and not libgpgme-pthread this fixes threading problems
with them.

libgpgme-pthread is removed but gpgme-config still supports
--thread=pthread for compatibility with find scripts.

be provided.  Not all flags are currently implemented.

 ./run-genkey --unprotected --force test@example.com

Create a new standard key with the given user id.  --force is used to
allow creating more than one key with that user id in the keyring.

 ./run-genkey --unprotected --force \
      test@example.com default default 2145826800

Creates a new standard key with an expiration date of 2037-12-31.

 ./run-genkey --unprotected --force \

This feature allows an application to declare that the encrypted or

What is missing is a way to return that information to the application
after decryption/verification.  This can be done by setting the
encoding of the output data object; however this requires some
internal additions to our processing model.

Fix regression with gpgsm 2.0 due to "OPTION with-secret".
* src/engine-gpgsm.c (gpgsm_assuan_simple_command): Do not terminate
on a status lines.
--

This bug has been with us since the support for gpgsm: If there is no
status line handler but a status line is received anyway the command
handling loop terminates and thus the command/answer order gets out of
sync.  In the case of the bug report this is triggered by sending an
option which starts the agent and that starting emits a "PROGRESS"
status line.

The solution is not to stop reading after a status line but record a
possible error code and return that only after OK or ERR.

Since gcc 4.8 there is a regression in Mingw64 in that plain C

libgcc_s_sjlj.dll.  This is for example triggered by using long long
arithmetic on a 32 bit Windows (e.g symbol __udivdi3).

Note that we don't use this patch for the Qt version which, as C++

Bummer.  Why did I subtracted one from the size?  Did I assume a

Not a real problem though because malloc will anyway round up the

* src/sign.c (gpgme_op_sign_result): Test that invalid and valid
signatures add up to gpgme_signers_count().
--

When invalid and valid signatures do not equal gpgme_signers_count() it
means that there was a bad passphrase during signing after the first
signer. This leaves the result.signatures from previous signers intact
which isn't correct since gpg will report:

gpg: number of one-pass packets does not match number of signature
packets
gpg: can't handle this ambiguous signature data

during verify. So when this happens append the valid signatures to the
.invalid_signers list with .reason set to GPG_ERR_GENERAL.
