If connection loss occurs, it calls session_disconnect() eventually.
This function clears saved account data which is required for
reconnection. Therefore, when reconnect timer expires, we get errors:
02/06/2019 04:53:42: stderr: ERR: (profanity:17115): GLib-CRITICAL **:
04:53:42.305: g_key_file_has_group: assertion
'group_name != NULL' failed
02/06/2019 04:53:43: prof: ERR: Unable to reconnect, account no longer
exists: (null)
To solve it, don't clear the saved data in session_disconnect(). It will
be cleared properly on connection loss if reconnect timer is not
configured. But won't be cleared with /disconnect command.
So, after /disconnect the data will live in memory until the next
/connect.
Also, remove some copy-paste in connection loss path.
When connection is lost, profanity tries to disconnect what leads
to an infinite loop. The loop occurs, because connection_disconnet()
runs xmpp_run_once() separately and waits for XMPP_CONN_DISCONNECT
event. But it doesn't happen, because the connection object is
disconnected.
As solution, don't disconnect after XMPP_CONN_DISCONNECT is received.
Also, don't free libstrophe objects while the event loops executes,
because the event loop continues using objects after callbacks quit.
mblen will fail with return code -1 if the locale used by the unit tests
isn't available on the machine. This will lead to an off by one error in some
tests where the needle is at the end of the haystack.
Since prof_occurrences expect null-terminated strings, the character after
the needle can simply be found by incrementing the address of the found needle
with strlen(needle).
Unit tests on 32-bit architectures were failing due to
"cast to pointer from integer of different size" warnings.
mock_ptr_type silences those by first casting to uintptr_t.
`/occupants char` now sets a character that is displayed before the nick
in MUCs. Similar like `/roster char` is displaying a char for the roster.
Regards #690
This is actually not needed because result will always be set.
hartmann had problems building profanity on OpenBSD and he proposed this
patch.
Let's use it to make the compiler happy there.
`/occupants header char` now sets a character that is displayed before
the role (moderator, visitor..) in a room. Similar to `/roster header
char` is displaying a char for the roster.
