Ubuntu 17.04 launch results in segfault if the build was done
by GCC 6.2 (works fine with GCC 4.9). Backtrace shows that it
crashes in gtk_init_check() call somewhere in libmirclient and
tests show that it works fine with GDK_BACKEND=x11.
So we use gdk_set_allowed_backends() method to explicitly state
that we support only "x11" GDK backend, that way it doesn't try
to use libmirclient and it does not crash.
Fix#3176#3162
Also replacing the Buy keyboard button with Receipt if the invoice
was payed already (like in mobile apps). This required to move the
inline markup apply before the media apply in message editing.
Now we use only new authorization keys for signing in. If we are
preparing to sign in and we see, that some of the authorization
keys were not generated in this launch, but were read from file, we
destroy all existing auth keys and generate a completely new set.
ShellExecute() call reenters Qt event loop, so each time we
schedule a delayed action (like destroying FileLoader) and after
that we call ShellExecute (in psOpenFile) we destroy it inside
this call and can't use it after.
So now we perform ShellExecute calls only delayed (using task queue).
Fix a regression introduced in 8d354382a4 which caused an overflow
in _parAnalysis access. We were resizing _parAnalysis array for a
line width without the pending newline character while we used it
for painting a line including the pending newline character. It was
not a problem before, when we were trimming them from the end of
the string, but it results in a buffer overflow and crashes in the
lastest versions. So now we just don't include the newline in the
painted string, so it has exactly the same size as _parAnalysis.
A regression was introduced in 1.0.12 version which led to wrong
activations of the main window: if a custom popup menu was shown
for the tray icon or a custom notification was clicked.
If we want to pin a chat and we have reached the limit we now check
for a deactivated (converted to supergroup) chat that is pinned and
is not in the chats list and just silently unpin it if it is found.
Also possible UB fix for a waveform encoding and decoding.
Media::Player::Instance started to notify about all sound
playback updates, even for video files (which do not have
DocumentData filled in), while Media::Player widgets were
relying on the existance of DocumentData in each update.
