Reduce the total startup time of the application and maintain sufficient responsiveness of the UI during startup due to the following:
1. Load resume data from disk asynchronously in separate thread;
2. Split handling of loaded resume data in chunks;
3. Reduce the number of emitting signals.
PR #16840.
The goal is to improve responsiveness of qbt when CPU resources are scarce.
Instead of lowering libtorrent threads priority, it is chosen to raise main event loop thread
priority to avoid getting messy with libtorrent internals.
Also on Windows, threads doesn't inherit thread priority from the parent thread and it always
use the default (normal) priority.
PR #17278.
You can already control the cache size in libtorrent 1.2.x so it doesn't make sense to implement this limit for all use cases. Also there are some downsides to using working set size to limit memory usage such as unresponsive GUI when limit gets hit.
PR #17275.
Originally, it was just a wrapper for libtorrent::torrent_handle class, so it mimicked its name.
It was then transformed into a more complex aggregate, but the name was retained (just by inertia).
Unlike libtorrent::torrent_handle class in whose name "handle" means the pattern used,
it does not matter for qBittorrent classes and just eats up space in the source code.
Enable portable mode if "profile" directory exists in the app dir.
Remove "--portable" command line argument.
Add logging of current profile config directory.
Closes#9445.
It may be useful to have different configurations either for portable
versions or for debugging purposes. To implement this we add two
options, avaliable via command line switches
1. An option to change configuration name ("--configuration"). The name
supplied via this option is appended to
QCoreApplication::applicationName() to form "qBittorrent_<conf_name>"
name for the configuration files.
2. An option to provide a path do directory where all the settings are
stored (kind of profile directory). There is a shortcut "--portable"
which means "use directory 'profile' near the executable location".
In order to implement that we have to perform initialisation of the
profile directories before the SettingStorage and Preferences singletones
are initialised. Thus, options parsing shall be performed without defaults
read from preferences.
Huge thanks to paolo-sz for bringing this to my attention, for the various patches he tried to submit and for testing.
See issue #1984 for complete history.
Closes#1535.
All MainWindow child widgets use constructors with 'parent' parameter
that allows parent widget to delete them at its destruction.
Some other MainWindow cleanup code replaced to destructor.
Application manages MainWindow instance and remove it when aboutToQuit()
signal emitted.
Application process message and split it into params list itself (this
prevents code duplication).
Application store params unless other components ready to process them.
Application incapsulate all QMacApplication and SessionApplication logic
(this is too small to have separate classes).
Change project directory structure according to application structure.
Change 'nox' configuration option to something more meaningful 'nogui'.
Rename 'Icons' folder to 'icons' (similar to other folders).
Partially add 'nowebui' option support.
Remove QConf project file.
