GIFs get paused if some other layer is displayed above.
Media preview > Box or layer > Saved GIFs panel > Inline bot results.
If any of those is displayed, GIFs inside message history pause too.
WebDocument size field is not a reliable information,
it can be > 0 and != upload.WebFile size field, so just ignore it
and load all WebDocument files as files with unknown size.
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.
We load a WebDocument with an unknown size the same way as we load
normal photos with FileLocation, that doesn't contain size as well.
If the size information from WebDocument and upload.WebFile is
inconsistent we still fail to load the file.
New button type keyboardButtonBuy just shows a box with information.
WebDocument photo type is not supported yet, 'photo' is ignored.
Also HistoryMediaPtr is now implemented as a std::unique_ptr wrapper.
It seems that heavy using std::shared_ptr and std::make_shared
like it was before completely kills the compilation time.
Also HistoryItem::_create now uses perfect forwarding.
Read media information (image / song / video) in SendFileBox in the
same way it is read in FileLoadTask::process() and reuse it in
FileLoadTask if it was loaded already for the box.
Currently the build without implicitly included precompiled header
is not supported anyway (because Qt MOC source files do not include
stdafx.h, they include plain headers).
So when we decide to support building without implicitly included
precompiled headers we'll have to fix all the headers anyway.
When we load previous messages in chat history we add all authors
of the messages to lastAuthors in regular groups (so that we can
suggest them in mention autocomplete). The same logic was (blindly)
applied to supergroups lastParticipants list which is used not only
for the mention autocomplete but also in Profile members list. That
way we were showing there users who could've already left the group.
Now base::lambda can be copied and can wrap any immutable lambda.
For mutable lambdas there is base::lambda_once (which you're
supposed to call only once to pass data through lambda captures,
for example by using std::unique_ptr). Generally base::lambda is
passed by value and base::lambda_once is passed by rvalue reference.
User names in groups, text and links in messages and names
in files and shared contacts not can have different colors
in plain inbox / outbox messages and in selected messages.
Now we can use a separate color for selected parts in Text.
Also fixed drag-n-drop images from Firefox in Windows.
Also some additional colors added to themes palette:
HistoryToDown button now has separate colors.
Windows title bar and buttons have separate active/inactive colors.
