python: Fix wrong use of write.

2023-05-23T13:52:25Z

* lang/python/helpers.c (pyPassphraseCb): Use gpgme_io_writen. (_gpg_interact_cb): Ditto. * lang/python/helpers.h (write) [W32]: Remove bad write macro. -- GnuPG-bug-id: T6501 Using write(2) without checking for EINTR is a not a good idea. Futher gpgme_io_writen is the correct way to send data from a callback. This also fixed the wrong use of a simple macro for Windows.

python: Rename Python module from PyME to gpg.

2016-10-31T14:42:27Z

This follows weeks of discussion on the gnupg-devel mailing list. Hopefully it will make it easier for people using Python to use GnuPG in the future. Signed-off-by: Daniel Kahn Gillmor

python: Include 'config.h'.

2016-09-26T14:54:57Z

* lang/python/Makefile.am: Pass 'top_builddir' to 'setup.py'. * lang/python/gpgme.i: Include 'config.h'. * lang/python/helpers.c: Likewise. * lang/python/helpers.h: Likewise. * lang/python/setup.py.in: Make sure that 'config.h' can be found. -- Fixes build on 32 bit platforms with large file support. Signed-off-by: Justus Winter

python: Add a flag identifying in-tree builds.

2016-08-02T16:45:10Z

* lang/python/helpers.c (pyme_in_tree_build): New variable. * lang/python/helpers.h (pyme_in_tree_build): New declaration. * lang/python/pyme/version.py.in (in_tree_build): New variable. * lang/python/setup.py.in: Rework macro handling, set 'IN_TREE_BUILD' as appropriate.

python: Rename exported functions.

2016-07-28T13:26:43Z

Avoid the name pygpgme, as this is the name of another popular Python binding for GPGME. This commit renames all functions that are exported to the Python world. * lang/python/helpers.c: Rename all exported functions. * lang/python/helpers.h: Likewise. * lang/python/pyme/core.py: Likewise. Signed-off-by: Justus Winter

python: Rename private functions.

2016-07-28T13:26:43Z

Avoid the name pygpgme, as this is the name of another popular Python binding for GPGME. This commit renames all functions that are not exported to the Python world. * lang/python/gpgme.i: Rename all private functions. * lang/python/helpers.c: Likewise. * lang/python/helpers.h: Likewise. * lang/python/private.h: Likewise. Also move the SWIG runtime helper prototypes here. Signed-off-by: Justus Winter

python: Expose less functions to the Python world.

2016-07-28T08:23:32Z

* lang/python/Makefile.am (EXTRA_DIST, COPY_FILES): Add new file. * lang/python/gpgme.i: Include new file and add comments. * lang/python/helpers.c: Include new file. * lang/python/helpers.h: Move functions we do not need to expose... * lang/python/private.h: ... here. 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: 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
