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.
This new command attempts to send malformed utf8 string to current chat with
dc_send_text_msg() function. Currently, instead of error code it causes
application crash with following backtrace:
thread 'main' panicked at 'Non utf8 string: '[255]' (Utf8Error { valid_up_to: 0, error_len: Some(1) })', src/dc_t

- remove usage of "attr.s" across the code
- make msg.set_file() copy a file into blobdir if it isn't already
- regroup tests
- add set_draft/get_draft API
pattern -- re-indentation will come after this commit with a pure application of "cargo fmt"

This patch changes output of following command (from README.md)
$ cargo run --example repl -- /tmp/main.db
from
First time init: creating tables in ""/tmp/main.db""
[...]
Opened ""/tmp/main.db"".
to
First time init: creating tables in "/tmp/main.db"
[...]
Opened "/tmp/main.db".
Note lack of double quotation mark, which was confusing and could have been
interpreted as part of file name.
Previously, dc_send_text_msg() silently returned 0 in case of incorrect
input. This way "send" command in repl reported "Sending failed" without
any clue what exactly went wrong.
dc_location_t is an incomplete copy of _dc_location
The difference is that it lacks `int independent` field.
As a result, calloc did not allocate memory for this field.
deltachat-core (C version) has only one dc_location_t, that includes the last field.
This is writes pkg-config/deltachat.pc file in the target directory,
using the PREFIX environment variable at build time. If this is
undefined at build time /usr/local is used.
For a few of the locations where error handling is done correctly this
does the right thing. For most other places it gracefully ignores any
issues which is what the original code did as well. Errors are
already logged by the called functions in those cases.
- Pass extra_link_args when using an installed libdeltachat
- Allow setting the liveconfig by envvar
- Show lifeconfig path in the pytest summary line
- Pass required envvars through tox
- Fix broken liveconfig passing in run-integration-test.sh
PEP-0394 (https://www.python.org/dev/peps/pep-0394/) recommends to use more specific shebangs.
For example, Debian allows /usr/bin/python to be configured to python2 via `update-alternatives python`, but the script does not work with Python 2.
