-Changelog
-=========
-
-__3.0.10__
-----------
-
-* Removed C style casts and eliminated all clang warnings. Fixed `instanceId`
- reading from only one byte in the message deserialization. Cleaned up
- serialization code using `QDataStream`. Changed connection type to use
- `quint8 enum` rather than `char`.
-* Renamed `SingleAppConnectionType` to `ConnectionType`. Added initialization
- values to all `ConnectionType` enum cases.
-
- _Jedidiah Buck McCready_
-
-__3.0.9__
----------
-
-* Added SingleApplicationPrivate::primaryPid() as a solution to allow
- bringing the primary window of an application to the foreground on
- Windows.
-
- _Eelco van Dam from Peacs BV_
-
-__3.0.8__
----------
-
-* Bug fix - changed QApplication::instance() to QCoreApplication::instance()
-
- _Evgeniy Bazhenov_
-
-__3.0.7a__
-----------
-
-* Fixed compilation error with Mingw32 in MXE thanks to Vitaly Tonkacheyev.
-* Removed QMutex used for thread safe behaviour. The implementation now uses
- QCoreApplication::instance() to get an instance to SingleApplication for
- memory deallocation.
-
-__3.0.6a__
-----------
-
-* Reverted GetUserName API usage on Windows. Fixed bug with missing library.
-* Fixed bug in the Calculator example, preventing it's window to be raised
- on Windows.
-
- Special thanks to Charles Gunawan.
-
-__3.0.5a__
-----------
-
-* Fixed a memory leak in the SingleApplicationPrivate destructor.
-
- _Sergei Moiseev_
-
-__3.0.4a__
-----------
-
-* Fixed shadow and uninitialised variable warnings.
-
- _Paul Walmsley_
-
-__3.0.3a__
-----------
-
-* Removed Microsoft Windows specific code for getting username due to
- multiple problems and compiler differences on Windows platforms. On
- Windows the shared memory block in User mode now includes the user's
- home path (which contains the user's username).
-
-* Explicitly getting absolute path of the user's home directory as on Unix
- a relative path (`~`) may be returned.
-
-__3.0.2a__
-----------
-
-* Fixed bug on Windows when username containing wide characters causes the
- library to crash.
-
- _Le Liu_
-
-__3.0.1a__
-----------
-
-* Allows the application path and version to be excluded from the server name
- hash. The following flags were added for this purpose:
- * `SingleApplication::Mode::ExcludeAppVersion`
- * `SingleApplication::Mode::ExcludeAppPath`
-* Allow a non elevated process to connect to a local server created by an
- elevated process run by the same user on Windows
-* Fixes a problem with upper case letters in paths on Windows
-
- _Le Liu_
-
-__v3.0a__
----------
-
-* Depricated secondary instances count.
-* Added a sendMessage() method to send a message to the primary instance.
-* Added a receivedMessage() signal, emitted when a message is received from a
- secondary instance.
-* The SingleApplication constructor's third parameter is now a bool
- specifying if the current instance should be allowed to run as a secondary
- instance if there is already a primary instance.
-* The SingleApplication constructor accept a fourth parameter specifying if
- the SingleApplication block should be User-wide or System-wide.
-* SingleApplication no longer relies on `applicationName` and
- `organizationName` to be set. It instead concatenates all of the following
- data and computes a `SHA256` hash which is used as the key of the
- `QSharedMemory` block and the `QLocalServer`. Since at least
- `applicationFilePath` is always present there is no need to explicitly set
- any of the following prior to initialising `SingleApplication`.
- * `QCoreApplication::applicationName`
- * `QCoreApplication::applicationVersion`
- * `QCoreApplication::applicationFilePath`
- * `QCoreApplication::organizationName`
- * `QCoreApplication::organizationDomain`
- * User name or home directory path if in User mode
-* The primary instance is no longer notified when a secondary instance had
- been started by default. A `Mode` flag for this feature exists.
-* Added `instanceNumber()` which represents a unique identifier for each
- secondary instance started. When called from the primary instance will
- return `0`.
-
-__v2.4__
---------
-
-* Stability improvements
-* Support for secondary instances.
-* The library now recovers safely after the primary process has crashed
-and the shared memory had not been deleted.
-
-__v2.3__
---------
-
-* Improved pimpl design and inheritance safety.
-
- _Vladislav Pyatnichenko_
-
-__v2.2__
---------
-
-* The `QAPPLICATION_CLASS` macro can now be defined in the file including the
-Single Application header or with a `DEFINES+=` statement in the project file.
-
-__v2.1__
---------
-
-* A race condition can no longer occur when starting two processes nearly
- simultaneously.
-
- Fix issue [#3](https://github.com/itay-grudev/SingleApplication/issues/3)
-
-__v2.0__
---------
-
-* SingleApplication is now being passed a reference to `argc` instead of a
- copy.
-
- Fix issue [#1](https://github.com/itay-grudev/SingleApplication/issues/1)
-
-* Improved documentation.

-SingleApplication
-=================
-
-This is a replacement of the QtSingleApplication for `Qt5`.
-
-Keeps the Primary Instance of your Application and kills each subsequent
-instances. It can (if enabled) spawn secondary (non-related to the primary)
-instances and can send data to the primary instance from secondary instances.
-
-Usage
------
-
-The `SingleApplication` class inherits from whatever `Q[Core|Gui]Application`
-class you specify via the `QAPPLICATION_CLASS` macro (`QCoreApplication` is the
-default). Further usage is similar to the use of the `Q[Core|Gui]Application`
-classes.
-
-The library sets up a `QLocalServer` and a `QSharedMemory` block. The first
-instance of your Application is your Primary Instance. It would check if the
-shared memory block exists and if not it will start a `QLocalServer` and listen
-for connections. Each subsequent instance of your application would check if the
-shared memory block exists and if it does, it will connect to the QLocalServer
-to notify the primary instance that a new instance had been started, after which
-it would terminate with status code `0`. In the Primary Instance
-`SingleApplication` would emit the `instanceStarted()` signal upon detecting
-that a new instance had been started.
-
-The library uses `stdlib` to terminate the program with the `exit()` function.
-
-You can use the library as if you use any other `QCoreApplication` derived
-class:
-
-```cpp
-#include <QApplication>
-#include <SingleApplication.h>
-
-int main( int argc, char* argv[] )
-{
- SingleApplication app( argc, argv );
-
- return app.exec();
-}
-```
-
-To include the library files I would recommend that you add it as a git
-submodule to your project and include it's contents with a `.pri` file. Here is
-how:
-
-```bash
-git submodule add git@github.com:itay-grudev/SingleApplication.git singleapplication
-```
-
-Then include the `singleapplication.pri` file in your `.pro` project file. Also
-don't forget to specify which `QCoreApplication` class your app is using if it
-is not `QCoreApplication`.
-
-```qmake
-include(singleapplication/singleapplication.pri)
-DEFINES += QAPPLICATION_CLASS=QApplication
-```
-
-The `Instance Started` signal
-------------------------
-
-The SingleApplication class implements a `instanceStarted()` signal. You can
-bind to that signal to raise your application's window when a new instance had
-been started, for example.
-
-```cpp
-// window is a QWindow instance
-QObject::connect(
- &app,
- &SingleApplication::instanceStarted,
- &window,
- &QWindow::raise
-);
-```
-
-Using `SingleApplication::instance()` is a neat way to get the
-`SingleApplication` instance for binding to it's signals anywhere in your
-program.
-
-__Note:__ On Windows the ability to bring the application windows to the
-foreground is restricted. See [Windows specific implementations](Windows.md)
-for a workaround and an example implementation.
-
-
-Secondary Instances
--------------------
-
-If you want to be able to launch additional Secondary Instances (not related to
-your Primary Instance) you have to enable that with the third parameter of the
-`SingleApplication` constructor. The default is `false` meaning no Secondary
-Instances. Here is an example of how you would start a Secondary Instance send
-a message with the command line arguments to the primary instance and then shut
-down.
-
-```cpp
-int main(int argc, char *argv[])
-{
- SingleApplication app( argc, argv, true );
-
- if( app.isSecondary() ) {
- app.sendMessage( app.arguments().join(' ')).toUtf8() );
- app.exit( 0 );
- }
-
- return app.exec();
-}
-```
-
-*__Note:__ A secondary instance won't cause the emission of the
-`instanceStarted()` signal by default. See `SingleApplication::Mode` for more
-details.*
-
-You can check whether your instance is a primary or secondary with the following
-methods:
-
-```cpp
-app.isPrimary();
-// or
-app.isSecondary();
-```
-
-*__Note:__ If your Primary Instance is terminated a newly launched instance
-will replace the Primary one even if the Secondary flag has been set.*
-
-API
----
-
-### Members
-
-```cpp
-SingleApplication::SingleApplication( int &argc, char *argv[], bool allowSecondary = false, Options options = Mode::User, int timeout = 100 )
-```
-
-Depending on whether `allowSecondary` is set, this constructor may terminate
-your app if there is already a primary instance running. Additional `Options`
-can be specified to set whether the SingleApplication block should work
-user-wide or system-wide. Additionally the `Mode::SecondaryNotification` may be
-used to notify the primary instance whenever a secondary instance had been
-started (disabled by default). `timeout` specifies the maximum time in
-milliseconds to wait for blocking operations.
-
-*__Note:__ `argc` and `argv` may be changed as Qt removes arguments that it
-recognizes.*
-
-*__Note:__ `Mode::SecondaryNotification` only works if set on both the primary
-and the secondary instance.*
-
-*__Note:__ Operating system can restrict the shared memory blocks to the same
-user, in which case the User/System modes will have no effect and the block will
-be user wide.*
-
----
-
-```cpp
-bool SingleApplication::sendMessage( QByteArray message, int timeout = 100 )
-```
-
-Sends `message` to the Primary Instance. Uses `timeout` as a the maximum timeout
-in milliseconds for blocking functions
-
----
-
-```cpp
-bool SingleApplication::isPrimary()
-```
-
-Returns if the instance is the primary instance.
-
----
-
-```cpp
-bool SingleApplication::isSecondary()
-```
-Returns if the instance is a secondary instance.
-
----
-
-```cpp
-quint32 SingleApplication::instanceId()
-```
-
-Returns a unique identifier for the current instance.
-
----
-
-```cpp
-qint64 SingleApplication::primaryPid()
-```
-
-Returns the process ID (PID) of the primary instance.
-
-### Signals
-
-```cpp
-void SingleApplication::instanceStarted()
-```
-
-Triggered whenever a new instance had been started, except for secondary
-instances if the `Mode::SecondaryNotification` flag is not specified.
-
----
-
-```cpp
-void SingleApplication::receivedMessage( quint32 instanceId, QByteArray message )
-```
-
-Triggered whenever there is a message received from a secondary instance.
-
----
-
-### Flags
-
-```cpp
-enum SingleApplication::Mode
-```
-
-* `Mode::User` - The SingleApplication block should apply user wide. This adds
- user specific data to the key used for the shared memory and server name.
- This is the default functionality.
-* `Mode::System` – The SingleApplication block applies system-wide.
-* `Mode::SecondaryNotification` – Whether to trigger `instanceStarted()` even
- whenever secondary instances are started.
-* `Mode::ExcludeAppPath` – Excludes the application path from the server name
- (and memory block) hash.
-* `Mode::ExcludeAppVersion` – Excludes the application version from the server
- name (and memory block) hash.
-
-*__Note:__ `Mode::SecondaryNotification` only works if set on both the primary
-and the secondary instance.*
-
-*__Note:__ Operating system can restrict the shared memory blocks to the same
-user, in which case the User/System modes will have no effect and the block will
-be user wide.*
-
----
-
-Versioning
-----------
-
-Each major version introduces either very significant changes or is not
-backwards compatible with the previous version. Minor versions only add
-additional features, bug fixes or performance improvements and are backwards
-compatible with the previous release. See [`CHANGELOG.md`](CHANGELOG.md) for
-more details.
-
-Implementation
---------------
-
-The library is implemented with a QSharedMemory block which is thread safe and
-guarantees a race condition will not occur. It also uses a QLocalSocket to
-notify the main process that a new instance had been spawned and thus invoke the
-`instanceStarted()` signal.
-
-To handle an issue on `*nix` systems, where the operating system owns the shared
-memory block and if the program crashes the memory remains untouched, the
-library binds to the following signals and closes the program with
-`error code = 128 + signum` where signum is the number representation of the
-signal listed below. Handling the signal is required in order to safely delete
-the `QSharedMemory` block. Each of these signals are potentially lethal and will
-results in process termination.
-
-* `SIGHUP` - `1`, Hangup.
-* `SIGINT` - `2`, Terminal interrupt signal
-* `SIGQUIT` - `3`, Terminal quit signal.
-* `SIGILL` - `4`, Illegal instruction.
-* `SIGABRT` - `6`, Process abort signal.
-* `SIGBUS` - `7`, Access to an undefined portion of a memory object.
-* `SIGFPE` - `8`, Erroneous arithmetic operation (such as division by zero).
-* `SIGSEGV` - `11`, Invalid memory reference.
-* `SIGSYS` - `12`, Bad system call.
-* `SIGPIPE` - `13`, Write on a pipe with no one to read it.
-* `SIGALRM` - `14`, Alarm clock.
-* `SIGTERM` - `15`, Termination signal.
-* `SIGXCPU` - `24`, CPU time limit exceeded.
-* `SIGXFSZ` - `25`, File size limit exceeded.
-
-Additionally the library can recover from being killed with uncatchable signals
-and will reset the memory block given that there are no other instances running.

-Windows Specific Implementations
-================================
-
-Setting the foreground window
------------------------------
-
-In the `instanceStarted()` example in the `README` we demonstrated how an
-application can bring it's primary instance window whenever a second copy
-of the application is started.
-
-On Windows the ability to bring the application windows to the foreground is
-restricted, see [`AllowSetForegroundWindow()`][AllowSetForegroundWindow] for more
-details.
-
-The background process (the primary instance) can bring its windows to the
-foreground if it is allowed by the current foreground process (the secondary
-instance). To bypass this `SingleApplication` must be initialized with the
-`allowSecondary` parameter set to `true` and the `options` parameter must
-include `Mode::SecondaryNotification`, See `SingleApplication::Mode` for more
-details.
-
-Here is an example:
-
-```cpp
-if( app.isSecondary() ) {
- // This API requires LIBS += User32.lib to be added to the project
- AllowSetForegroundWindow( DWORD( app.getPrimaryPid() ) );
-}
-
-if( app.isPrimary() ) {
- QObject::connect(
- &app,
- &SingleApplication::instanceStarted,
- this,
- &App::instanceStarted
- );
-}
-```
-
-```cpp
-void App::instanceStarted() {
- QApplication::setActiveWindow( [window/widget to set to the foreground] );
-}
-```
