holger krekel	bf692b5739	split qr tests	2019-09-19 19:38:19 +02:00
Dmitry Bogatov	030aec7373	Read example GPG keys from files using `include_str!` For consistency with other tests that use example public and private keys, replace use of `concat!` macro with `include_str!`. This way, key data embedded into source with single line of code.	2019-09-19 18:57:39 +02:00
B. Petersen	6a351de4f9	cargo fmt	2019-09-19 18:42:29 +02:00
B. Petersen	bbff1c9c3e	test that bad credentials do not panic	2019-09-19 18:42:29 +02:00
B. Petersen	bbb8144129	do not panic when 0 (=failure) is passed to the progress! macro	2019-09-19 17:00:01 +02:00
Friedel Ziegelmayer	83f3e23297	improve python caching (#468 ) (@dignifiedquire and @hpk42) - introduce rust-caching to python test runs - skip release and ffi runs, they are check using python bindings - shuffle files such that ci_scripts/ contains all the ci scripts - partly parallelize python tox runs	2019-09-19 13:10:19 +02:00
B. Petersen	4f880932ae	change oder of typedefs, function-definitions and defines as c is top-down, we start with the typedefs so that functions can use them freely. after that, the functions are declared and finally the #defines (for less noise in the function sections). grouping is done by classes.	2019-09-19 12:58:26 +02:00
B. Petersen	62e8c2497c	add missing doxygen commands, fix typo	2019-09-19 12:58:26 +02:00
Simon Laux	37f854be3e	Add provider info functions to the FFI API A lot of work from @Hocuri and @Simon-Laux mostly. This exposes the API of the deltachat-provider-overview crate on the deltachat FFI API, allowing clients to use it to help users set up their accounts.	2019-09-19 07:17:44 +02:00
Dmitry Bogatov	e0e82e1877	Fix ffi interoperability issue Clients expect empty "dbfile" argument to be treated as NULL value. This change fulfills their expectations. Closes: #530	2019-09-19 07:15:35 +02:00
Dmitry Bogatov	95d8665dbe	Refine signature of dc_get_oauth2_access_token() Previously, `dc_get_oauth2_access_token` accepted "flags" argument, that actually had only one possible field: 0x1 == DC_REGENERATE. This change replaces "flags" argument with single boolean argument "regenerate".	2019-09-18 19:29:39 +02:00
dignifiedquire	8667de994e	use proper Result instead of Option for encryption and decryption	2019-09-18 19:21:41 +02:00
holger krekel	cee0e22ce7	fix #538 -- don't crash on wrong setup codes for ac-message, don't use "expect(), added test	2019-09-18 19:21:41 +02:00
holger krekel	dc8a2f54e5	use utf8 lossy strings for saved mime headers (as discussed on PR and IRC with @r10s)	2019-09-18 16:47:04 +02:00
dignifiedquire	b3bc5b2520	fix(receive_imf): do not attempt to convert raw body to utf8	2019-09-18 16:47:04 +02:00
B. Petersen	00e929afac	reformat: use shorter lines (max. 80 chats) and try to add linebreaks semantically	2019-09-18 15:20:34 +02:00
