When a source file contains an explicit include with a filename
following the "moc_<actual-filename>.cpp" pattern, then CMake's
AUTOMOC generation tool will recognize the matching pair and generate
the replacement header file and add the required include directory
entries.
For all files which do contain Q_OBJECT or similar declarations but do
not have an explicit include directive, the global mocs_compilation.cpp
file will still be generated (which groups all "missing" generated
headers).
The larger this global file is, the more expensive incremental
compilation will be as this file (and all its contained generated
headers) will be re-generated regardless of whether actual changes
occurred.
When we use the server error to respond to user's failing to start a
stream it is slow to return an error and unclear to the user what went
wrong. This diff introduces a simple settings check before attempting
to stream and catch and explain specific URL/key issues to the user.
In the case of preset services we check there is a Stream Key before
attempting to start a stream.
In the case of "custom" we only verify there is a URL since for some
services that's all that is required or the user may use user/password
authentication.
Pull UI validation and its helpers to their own class. This class will
be used to validate forms and perform UI-action checks such as
checking stream keys aren't empty and in this diff now holds the logic
to ensure there is a source before the person starts a stream.
