The user-visible change here is that it allows the FFI API to save
keys in the database for a context. This is primarily intended for
testing purposes as it allows you to get a key without having to
generate it.
Internally the most important change is to start using the
SignedPublicKey and SignedPrivateKey types from rpgp instead of
wrapping them into a single Key object. This allows APIs to be
specific about which they want instead of having to do runtime checks
like .is_public() or so. This means some of the functionality of the
Key impl now needs to be a trait.
A thid API change is to introduce the KeyPair struct, which binds
together the email address, public and private key for a keypair.
All these changes result in a bunch of cleanups, though more more
should be done to completely replace the Key type with the
SignedPublicKye/SignedPrivateKey + traits. But this change is large
enough already.
Testing-wise this adds two new keys which can be loaded from disk and
and avoids a few more key-generating tests. The encrypt/decrypt tests
are moved from the stress tests into the pgp tests and split up.
This should prevent accidental sending of unencrypted messages when
parent_is_encrypted returns an error. For example, if the database is
busy due to other thread activity, parent_is_encrypted should not return
false. Instead, message sending job should retry later.
Also create a common parent_query() function to make sure we use the
same message as a parent when determining if it is encrypted and when
actually replying to it.
This is a new feature in Rust 1.40, it means users outside the crate
will not be able to create these structs, allowing us to add fields
without breaking the public API.
This is the first experiment towards using structs to define the API.
It adds it as a new method on the existing Chat struct.
The types in this struct could improve as well as many other things.
But this is a straight forward translation of the existing json! macro
into a struct.
This effectively reverts
https://github.com/deltachat/deltachat-core-rust/pull/964 for chat.rs,
which in that PR was thought to fix something. So maybe something is
still broken? But after improving tests the previous code seems to be
correct.
- Update Python bindings to not always use dc_prepare_msg path when
sending messages with attachements. When using dc_prepare_msg the
blobs need to be created in the blobdir since they will not get
copied and many tests where not doing this.
- Add a test that ensures that calling dc_prepare_msg with a
file **not** in the blobdir fails.
- Add a test that ensures that calling dc_send_msg directly with a
file **not** in the blobdir copies the file to the blobdir. This
test cheats a little by knowing what the filename in the blobdir
will be which is implementation-dependent and thus a bit brittle.
But for now it proves correct behaviour so let's go with this.
- Improve the test_forward_increation test to ensure that the
in-creation file only has it's final state before calling
dc_send_msg. This checks the correct file data is sent out and not
the preparing data, this fails with the chat.rs changes in
#964 (reverted here to make this work again). Also fix the test to
actually create the in-creation file in the blobdir.
- Fix test_send_file_twice_unicode_filename_mangling to not use
in-creation. It was not creating it's files in the blobdir and that
is an error when using in-creation and it didn't seem it was trying
to test something about the in-creation logic (which is tested in
test_increation.py already).
- Fix Message._msgtate code which presumably was not used before?
- Rename `BlobObject::create_from_path` to
`BlobObject::new_from_path`. All the `BlobObject::create*` calls
now always create new files which is much more consistent. APIs
should do what is obious.
