* Make dc_msg_get_summarytext_by_raw safe
* use dc_truncate method in all places
* Fix tests and add docs to dc_truncate()
* Make text argument an AsRef<&str> and rename type_0 to viewtype
* Fix too early return in dc_msg_get_summarytext_by_raw. Fixes https://github.com/deltachat/deltachat-core-rust/issues/313
This marks the function safe and returns Result, it also now returns
the ConfiguredAddr since it has to look this up anyway and it makes
testing more easy. Turns out it reduces some duplicate SQL query in
some callers too.
More test code has been moved from dc_imex to test_utils as it's
more genrally applicable.
* refactor(contact): rename and rusty memory allocations
* refactor(contact): use enum to indidcate origin
* refactor(contact): safe blocking and unblocking api
* refactor(contact): only safe and no more cstrings
Add a trait for str.strdup() to replace to_cstring() which avoid the
signature ambiguity with .to_string().
Also instruduce CString::yolo() as a shortcut to
CString::new().unwrap() and use it whenever the variable does can be
deallocated by going out of scope. This is less error prone.
Use some Path.to_c_string() functions where possible.
This change removes global override of `non_shake_case' warning and replaces it
with per-function overrrides. This way, compiler will complain about style
guide violation in new code.
It should be noted, that `rustc' is not smart enough to emit warning when
override is no longer needed, it must be checked manually.
With this change, passing invalid utf8 string to `dc_send_text_msg' does not
crash application, it prints warning and returns error code.
It should be admitted that this fix is sub-optimal: if input C string is valid
utf8 (which is likely), result of successful conversion to `&str' is discarded
in `dc_send_text_msg', and the same input C string is converted again with
`as_str' in `prepare_msg_raw'.
It is not clear how to fix it in non-disruptive way, since input C string is
passed down to call stack as part of `dc_msg_t' struct, which is part of C ABI.
pattern -- re-indentation will come after this commit with a pure application of "cargo fmt"
- bring back comment from C code
- make some path helpers return bool
