"A notable implementation where std::random_device is deterministic is old
versions of MinGW (bug 338, fixed since GCC 9.2)."
Although time is less random off Windows, we don't need a strongly random
number for this, and using time avoids having to use platform specific code.
Fix#2917
* Reorder class data members and/or constructor initialisers to match,
reducing confusion about when members will be initialised.
* Remove (most) unused variables. Not removed: some global variables with
`TODO(sudden6)` on them for using them in the future. I don't know how
far into the future sudden6 wants to use them, so I left them there for
now.
* Distinguish different bootstrap nodes in the logs by index in the
bootstrap node list. Originally, we used to log the address/port of the
node we're bootstrapping to. This was removed out of privacy concerns
(even though the bootstrap nodes are public). This made the logs much
less useful when debugging why the client isn't connecting. Having
indices makes it easier to see that different nodes are being selected,
and makes it possible to determine which node was selected.
* Explicitly cast unused results of Tox API functions to `void` when all
we want is to know whether the function succeeds or not.
* Don't try to `#include <unistd.h>` on Windows. It does not exist on
MSVC.
* Remove extra `;` after function definitions.
* Remove reference indirection of QJsonValueRef, since a copy of that ref
(small pointer-like object) has to be made anyway when iterating over
QJsonArrays.
* Make some file-scope global state `static`.
* Use `nullptr` instead of `NULL`.
* Add `#if DESKTOP_NOTIFICATIONS` around the code that implements desktop
notifications, so it becomes a bit easier to compile everything with a
single compiler command - useful for manually running static analysers.
* Fix an error on MSVC where `disconnect` is looked up to be a non-static
member function and the `this` capture is missing.
* Consistently use `struct` and `class` tags for types.
* Use references in ranged-for where it reduces copies.
* Move private static data members out of the Style class and into
file-local scope. There is no need for them to be in the class. Also
marked them `const` where possible.
* Removed unused lambda capture.
* Ensure qTox can compile under NDEBUG with `-Wunused-variable` by
inlining the unused variable into the `assert` that was its only
target.
* Minor reformatting in core_test.cpp.
Our previous SQLCiper upgrade code attempted to set SQLCipher 4.0
default params. If SQLCipher 3.x was used at that time, it would result
in only half upgrading the params, since SQLCipher 3.x doesn't support
PRAGMA cipher_hmac_algorithm or PRAGMA cipher_kdf_algorithm. This means
that our databases could be saved with any of three sets of SQLCipher
params.
This will prevent qTox from auto-accepting arbitrarily large avatars. Avatars
are already limited by TCS 2.2.4 to 64KB, so we would only receive larger
avatars from badly behaving clients.
Don't add Wzero-as-null-pointer-constant by default, since on older Qt
versions that we stil support and that our CI runs agains, Qt API themselves
cause warnings which lead to build errors all over the place.
Fix#6008
Enable warnings for both. Favour casting to signed rather than casting to
unsigend for comparisons. Per isocpp's core guidelines ES.102, signed
arithmetic gives more expected results. If we need one extra bit of range,
using longer signed types achives that.
Fix#6010Fix#6012
Message caching is handled by SessionChatLog in memory even when history is
disabled. ChatLog doesn't need to worry about how the messages its rendering
are being stored. Dynamic loading up and down in chatlog is sitll functional.
Checking if history pointer is valid is not sufficient, the setting must also
be checked. This caused asserts in history when history was disabled in
settings.
Makes the CoreAV thread own all ToxCalls in order to prevent signals
from being emitted via a Direct connection from Audio to CoreAV.

c-toxcore calls the groupCallCallback from it's main thread instead of
the ToxAV thread as expected, this was triggering an assertion.
Aditionally the destructors of Core and CoreAV were fixed, because they
now either crashed or deadlocked qTox when it was closed while a group
call was still running.
(cherry picked from commit 141cbf8870)
This actually fixes two problems:
1) CoreAV and Audio thread both locked the callsLock and audioLock in
different orders, resulting in a deadlock of both threads. This fixed by
using a ReadWriteLock in the CoreAV thread.
2) Multiple functions were emitting signals while holding a lock. This
is unsafe, because the connected slot may acquire any other lock. This
is fixed by releasing the locks before emitting signals.
(cherry picked from commit 4b9e4a571d)
It doesn't really make sense to assert that the callbacks are coming
from any other thread than CoreAV, when we actually want to ensure the
callback is coming from Core thread.
Remove over agressive assert from sendGroupCallAudio(...), this function

Additionally remove the call timeout, it creates timers from different

(cherry picked from commit 98cfe9838f)
This commit fixes the behavior when a message is received while the
chatlog is scrolled to the bottom. With this change, the chatlog will
stick to the bottom when it is scrolled all the way down. If it is
somewhere in the middle (e.g. for search) the chatlog will not change
its position.

The netcam covers much of the chat in groups, and has nothing to show since
group video calls aren't possible. Who is speaking in call is already shown by
the bold names at the top of the group, taking much less space.

As of 2019-10-09, toxme.io was taken offline permanently. Remove UI and code
in qTox relating to it. Revert this commit if it comes back online in the
future.

When re-evaluating our dependencies we decided that the update bridge
has a high potential for security issues because it's not widely used.
Additionally similar functionality is already present in qTox.

* When the DB schema was too new we were accessing history anyways. This
has potential to just completely corrupt the DB
* When history was disabled there was a chance we would attempt to write
to history anyways. Added more checks in this area
* Chatform was accessing invalid iterators when there were no displayed
messages. Added a guard for this case
Group calls are supposed to show the name of each member under their
avatars. The color of the text was previously fixed to white regardless
of the background ignoring the color of the background.
This fix ensures that the background color is not the same color as the
label text
Avatars for group members currently in a call are resized depending on
the area they are displayed in. Previously a scrollbar would appear and
disapear based on the size of the contents. This resulted in
oscillations that ended in a SIGSEGV.
This fix avoids the oscillations by fixing the scrollbar to always be
shown

The call to Core::getGroupPeerNames is expected to return a list where
the index in the list is the group member id. In any error case we were
previously breaking this constraint. It turns out that every time
someone joins a group we call this function before they have a valid
name resulting in their id not being added to the list.
This fix ensures that the list coming out of Core::getGroupPeerNames
always has a full list.
Fixes#5838
On application close we used to access invalid memory associated with
the audio subsystem. This was because on destruction of static variables
we tried to access state associated with an already destructed item.
These variables seem to have no good reason to be static. They should be
tied to a single CoreAV instance and are only accessed through an
existing CoreAV instance.
The previous implementation of hiding the date line would cause 100% cpu
usage. When the date line was shown it would hide the top line, causing
the date line to be hidden again due to a state change in which dates
was visible.
This is a minimal patch to work around the issue by pretending the line
covered by the date line is the first visible line when the dateline is
shown

Before a bug in qTox would make it possible for a user to try to send an empty
action type message. This would fail to send at toxcore, but still be persisted
in history, causing it to fail every time FauxOfflineEngine tried to resend
it. Moving these stuck messages into the broke_messages table will stop qTox
from attempting to deliver them on each connect, and display in the GUI to
users that the messages aren't really pending anymore.
Otherwise sending just "/me " calls down to core with 0-length action, which
causes a toxcore send error.
There may be messages that are stuck in history as pending with "/me " content,
causing them to fail to send on every start. Those should be moved to the new
broken_messages table, similar to stuck pending messages from #5776. There's no
reason this fix to stop adding more broken messages needs to wait on the
history fix, though.
"Sent" to "Delivered", since that's what we're tracking also rename "isOffline"
to "isPending", which is boolean the same, but "isOffline" was opposite of its
correct value before, so boolean reverse the assignment.
Fix#5776
Due to a long standing bug, faux offline message have been able to become stuck
going back years. Because of recent fixes to history loading, faux offline
messages will correctly all be sent on connection, but this causes an issue of
long stuck messages suddenly being delivered to a friend, out of context,
creating a confusing interaction. To work around this, this upgrade moves any
faux offline messages in a chat that are older than the last successfully
delivered message, indicating they were stuck, to a new table,
`broken_messages`, preventing them from ever being sent in the future.
This allows upgrade steps to query the db at the last version and run C++ code
on the results, then do a single transaction to make the upgrade, instead of
all actions of each upgrade step being required to be part of the overall
upgrade transaction.
* Fix callback hookup order in ChatHistory
* Add correct call to SessionChatLog to insert an unfinished message
* Fix incorrect logic in parsing History database response

This commit makes LoginScreen return QDialog::Rejected (0) and
QDialog::Accepted (1) instead of C standard return values. This should be more
robust with regards to special cases in Qt implementation.
Fixes#5781
qTox added specialized tray icon backends over time to work around bugs with
the default implementation, since then our GTK+2 backend has stopped working,
our appindicator backend was never selected by default by cmake, and
statusnotifier was never selected at SystemTrayIcon construction, leaving us
only ever using the broken GTK+2 backend, or theoretically the Unity backend,
which I didn't see selected on Ubuntu 16.04 Unity. In all other cases we would
fall back to the Qt backend.
Qt icon has improved over time, and our platform specific icons have become
stale, with GTK+2 becoming deprecated and GTK+3 not having a similar feature,
QSystemTrayIcon has been tested on a variety of DEs and works as well or better
in all cases, as shown in the table at

Errors are parsed and printed, but which specific node is being connected to
isn't very relevant to any errors that would occur, and the nodes list is
already updated to prune offline nodes based on nodes.tox.chat periodically.
This provides some extra privacy about which connections are being made,
even though the bootstrap nodes are already public.
Use a macro to embed line number of call sight, instead of just using line
number of log site, since logger functions can be called from different
toxcore API usages.
ChatLogIdx is a strong type where the underlying data is only supposed
to be used in very rare circumstances. The ChatLog providing the indexes
provides no guarantees about what the first ChatLogIdx or last
ChatLogIdx will be. This commit removes unnecessary casts to underlying
data and fixes assumptions made about the underlying data
The button didn't work that well and caused all kinds of issues inside
the code, so I replaced it by a notice that changes to the Advanced
settings only apply after a restart of qTox.
In the process I also removed all code that was exclusively used for
that feature.
We may add it back later when qTox's internal architecture makes it less
cumbersome.
Fix#5763
remove restriction to not update messages not in last slot in chatform,
allowing completed messages to be timestamped at any position. Fixes
stuck spinner in cases where a second message was sent quickly, or an
incoming message was received before the last send message was completed.
This is a quick fix to load settings before Core is started. Ideally
this would not need to be inside the Profile, but at the moment the
decryption key is not available before starting Core.
