Get list of original recipients after decrypting

Indeed. The native interface has not updated for a while. Pushed a fix: 84b4934

Wow, cool, that was fast, thanks a lot!

Unfortunately when trying to use it, I always end up with gpgme_op_decrypt_result': NULL pointer given (ArgumentError). The code works fine without the GPGME::gpgme_op_decrypt_result(ctx) call.

Here's what I'm trying to use:

  options = {}
  plain_data   = GPGME::Data.new(options[:output])
  cipher_data  = GPGME::Data.new(encrypted)

  rctx = []
  err = GPGME::gpgme_new(rctx)
  exc = GPGME::error_to_exception(err)
  raise exc if exc
  ctx = rctx[0]

  err = GPGME::gpgme_op_decrypt_verify(ctx, cipher_data, plain_data)
  exc = GPGME::error_to_exception(err)
  raise exc if exc

  GPGME::gpgme_op_decrypt_result(ctx)

  GPGME::gpgme_release(ctx)

  plain_data.seek(0)
  decrypted_val = plain_data.read

Well, the code works here. Could you provide the complete error message? By the way, a simpler test case can be something like:

require 'gpgme'

ctx = GPGME::Ctx.new
cipher = GPGME::Data.new(ARGF)
ctx.decrypt(cipher)
p ctx.decrypt_result

and you will get:

$ ruby decrypt.rb test.txt.gpg
#<GPGME::DecryptResult:0x0000000186bbd0 @wrong_key_usage=0, @recipients=[#<GPGME::Recipient:0x0000000186bb58 @pubkey_algo=1, @keyid="50AD4600C8C530D6", @status=0>], @file_name="test.txt">

I've tried on different machine, and very same code seems to work fine (both machines are OS X Mavericks, with ruby 2.0.0p247, used same way to create & install gem). I'll try to find out more what's the issue when I'll get back home to the other machine.

hey, I've added tests for this (and missing attr_readers):
https://github.com/ueno/ruby-gpgme/blob/master/test/ctx_test.rb#L44
and they seems to be ok on travis:
https://travis-ci.org/ueno/ruby-gpgme

Closing this for now. If you find anything more, please reopen.

Thanks, I wasn't able to reliably reproduce this. It's somehow related to the version of compiler used to build the native extension, but as ruby & gcc weren't consistent across my machines, I've simply fixed this by rebuilding the gem using gcc48 provided by homebrew and I wasn't able to reproduce same error again since.

Hello

I can reliably reproduce this on OSX, Ubuntu, Debian, and Travis I've added a failing test on my fork to demonstrate the behaviour.
