Signed-off-by: Justus Winter

python: Port more tests.

2016-07-08T16:03:36Z

* lang/python/tests/Makefile.am (pytests): Add new file. * lang/python/tests/t-import.py: New file. Signed-off-by: Justus Winter

python: Fix raising stashed exceptions.

2016-07-08T09:45:08Z

Fixes an issue with newer versions of Python. * lang/python/helpers.c (pygpgme_raise_callback_exception): Be more careful when restoring the exception. Signed-off-by: Justus Winter

python: Fix distcheck.

2016-07-07T12:10:36Z

* lang/python/INSTALL: Drop obsolete file. * lang/python/Makefile.am (EXTRA_DIST): Add missing files. (CLEANFILES): Remove generated files. (clean-local): Fix permissions of copied files. * lang/python/tests/Makefile.am (TESTS): Use our own setup and teardown scripts. (EXTRA_DIST): Add missing files. * lang/python/tests/final.py: New file. * lang/python/tests/initial.py: Likewise. Signed-off-by: Justus Winter

python: Improve autmatically generated docstrings.

2016-06-16T12:19:17Z

* lang/python/gpgme.i: Add comment. * lang/python/pyme/core.py (__getattr__): Rewrite automatically generated doctrings for the wrapper methods. Signed-off-by: Justus Winter

python: Make result objects more robust.

2016-06-16T12:19:17Z

Results returned by the GPGME are fragile, i.e. they are only valid until the next operation is performed in the context. We cannot arbitrarily constrain the lifetime of Python objects, we therefore create deep copies of the results. * lang/python/gpgme.i (gpgme_tofu_info_t): Turn these into a list. (gpgme_*_result_t): Create deep copies of these objects. * lang/python/helpers.c (pygpgme_wrap_fragile_result): New function. * lang/python/helpers.h (pygpgme_wrap_fragile_result): New prototype. * lang/python/pyme/results.py: New file. Signed-off-by: Justus Winter

python: Avoid creating SWIG proxy classes.

2016-06-16T12:19:17Z

* lang/python/Makefile.am (gpgme_wrap.c): Use '-builtin' to make SWIG generate builtin types for c types. * lang/python/gpgme.i (pygpgme_wrap_gpgme_data_t): Adapt slightly. Signed-off-by: Justus Winter

python: Simplify wrapping glue.

2016-06-16T12:19:17Z

* lang/python/pyme/core.py: Rename '_getctype' to '_ctype' and turn it into a string. Likewise rename '_getnameprepend' to '_cprefix'. * lang/python/helpers.c: Adapt accordingly. Signed-off-by: Justus Winter

python: Rework callbacks.

2016-06-16T12:19:17Z

Simplify how the lifetime of callback arguments is managed. * lang/python/gpgme.i (gpgme_edit_cb_t): Check arguments. (PyObject_p_p, void_p_p): Drop rather dangerous interface. (pygpgme_unwrap_gpgme_ctx_t): New function. * lang/python/helpers.c (pygpgme_clear_generic_cb): Drop dangerous function. (pyPassphraseCb): Assert contract. (pygpgme_set_passphrase_cb): Use Python's calling convention so that we can raise exceptions. Hand in 'self', get the wrapped object, and simply store the hook data as attribute of the wrapper object. (pyProgressCb, pygpgme_set_progress_cb): Likewise. (pygpgme_set_status_cb): Likewise. (pygpgme_data_new_from_cbs): Likewise. * lang/python/helpers.h (pygpgme_clear_generic_cb): Drop prototype. (pygpgme_set_passphrase_cb): Update prototype. (pygpgme_set_progress_cb): Likewise. (pygpgme_set_status_cb): Likewise. (pygpgme_data_new_from_cbs): Likewise. (pygpgme_unwrap_gpgme_ctx_t): New prottotype. * lang/python/pyme/core.py (Context, Data): Update callsites. Signed-off-by: Justus Winter

python: Wrap objects implementing the buffer protocol.

2016-06-16T12:19:17Z

* lang/python/Makefile.am: Add the toplevel source directory to CFLAGS when compiling the bindings so that we can use private header files. * lang/python/gpgme.i (gpgme_data_t): Rework the object wrapping. Do not create a Python wrapper object, merely a gpgme_data_t object, and keep references to buffer objects, if any. If necessary, update the buffer after the function call. (pygpgme_wrap_gpgme_data_t): New function. * lang/python/helpers.c (object_to_gpgme_data_t): Rework object wrapping. Also wrap objects implementing the buffer protocol. * lang/python/helpers.h (object_to_gpgme_data_t): Update prototype. (pygpgme_wrap_gpgme_data_t): New prototype. * lang/python/tests/t-idiomatic.py: Demonstrate this. Signed-off-by: Justus Winter
