* Add support for component aliasesArttu Tarkiainen2023-09-141-0/+9
| | | | | | | | | | | | | | | | | | Introduce concept of component aliases, which act as an alternative way for referring a set of related components. Component aliases are declared in an alias definition file, which is included to the created installer's binary layout as a resource. The file lists the available aliases, including metadata - such as name, version, and description - and the list of components and other aliases the alias requires. Aliases can be referred only from the CLI for the time being, with the supported commands 'install' and 'search'.

* Add common base class for the installer calculator classesArttu Tarkiainen2023-02-081-30/+10
| | | | | | | | As the classes already share similar features and public API, it would make sense to inherit a common abstract class to define the interface. Change-Id: I7ed278b1b049b7ec12c4401e55fdf39306b0ab85 Reviewed-by: Katja Marttila <katja.marttila@qt.io>
* Cleanup installer calculator classesKatja Marttila2022-11-301-16/+11
| | | | | | | | | | | | | | As there are several optimizations done, the single click of component in component selection tree is not slow anymore. Cleaning the code so it is easier to maintain. Basically this revers commit a28cf55b5a5007c0dd952b3012c076d9da329f0f but as there are bug fixes made after that so pure revert could not be done.

* Optimize retrieving components by nameArttu Tarkiainen2022-10-111-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The PackageManagerCore::componentByName(const QString &name) -function is called repeatedly by the InstallerCalculator class and at minimum once for each install script, because we automatically inject a snippet which stores the return value of the function in the 'component' variable for the script context. Create a <name, component> hash once per each component model reset to make the lookups faster: * This avoids constructing a flat list of components and all their descendants again and again when calling the function. * The linear lookup from the component list is slow because it calls componentMatches() for each element until the satisfactory component was found or the list ends. * The average time complexity of the key lookup from the QHash is constant even for large hashes.

* Fix bug when installer is not installing required componentsKatja Marttila2022-06-201-0/+1
| | | | | | | | | | | | | | | | | | | Components can be requested to install by several components using dependency. Components should have a reference count to inform how many components are requesting the install, so that the component can be removed from install when nobody has requested it, or user has not explicitly selected it for install. Dependency reference count was not calculated correctly, user selection was ignored if component was already added as dependency. Also if component which is added as dependency is also autodependency to same component should not increase the reference count, as the component is uninstalled when the reference count is zero. Having both autodependency and dependency would never cause the reference count to be zero.

* Fix updating autodependency componentsKatja Marttila2022-05-131-1/+2
| | | | | | | | | | | Autodependency components were always forcely updated, even if 'Deselect All' was selected in component selection page. Fixed so that the autodependency component update is updated only when one of its dependants is updated.

* Speed up component selection in component selection pagesKatja Marttila2022-04-281-15/+24
| | | | | | | | | | | | | | | | | If a lot of components are installed, maintenancetool was slow to select/unselect a single component. This was caused because the whole tree's components were recalculated. Fixed so that only the selected/unselected components and their dependencies and autodependencies are recalculated instead of whole tree. This change speeds up clicking tree item from zero to 90 percent, depending on how much components are already installed. The more components are installed as autodependency, the slower it gets to select the items.

* Make installer to check the dependency versionKatja Marttila2017-03-231-2/+2
| | | | | | | | | | | | | | Installer was able to install dependency correctly. However, it ignored the version dependency might have. Dependencies>componentA->=4.0</Dependencies> If there was already a dependency installed with lower version number, the newer version, which was required by the selected component, was not installed. Fixed so that maintenancetool will not only check if the dependency is installed but also the installed version.
