If there are no modules at all before an exec: section is
reached (e.g. right now due to a bug in module-loading)
then the last() call would crash. Instead, use a nullptr
for the last-module-loaded.
While here, apply code-formatting.
For methods that log a bunch of things, and which want to
consistently use SubEntry, but don't know when the **first**
log entry is within the method, Logger::Once can be used
to log one regular message (with function info) and the
rest are subentries.
- parameter instanceKey was left over from previous work that
special-cased the weight of Python modules.
- while here, consistently do `~T() override`
With 1 CPU, Calamares still spawns 9 threads or so: eventloop,
dbus loop, QML loop, ... many of those are invisible to the
application. Contention occurs on startup when the UI is constructed,
and we end up with the module manager creating widgets alongside,
or ahead of, the main window UI. This can result in deadlock:
- in CalamaresApplication::initViewSteps
- in QML imports
This is partly because the signal-slots connections get "deep":
from loadModules() we emit *modulesLoaded* which ends up showing
the main window in initViewSteps(). Avoid this with a QTimer:
drop back to the event loop and release whatever locks are held,
so the QML thread can get on with it already. Then the timer
goes off and the view steps are created.
- point to main Calamares site in the 'part of' headers instead
of to github (this is the "this file is part of Calamares"
opening line for most files).
- remove boilerplate from all source files, CMake modules and completions,
this is the 3-paragraph summary of the GPL-3.0-or-later, which has
a meaning entirely covered by the SPDX tag.
- CC0-1.0 for the uninteresting version-headers
- GPL-3.0-or-later for the services
- add SPDX identifiers to Calamares C++ libraries and application sources
- add SPDX identifiers to Calamares QML (panels and slideshow)
- the `qmldir` is a list of names of things in the directory,
so CC0-1.0 it as "uninteresting"
- QRC files are lists of names of things in the directory,
so CC0-1.0 them as well
- The weight is the module (instance) weight, which can be
- the default weight of 1
- the weight specified for the module (in module.desc / the module
descriptor; this defaults to 1, above)
- the weight specified for the instance (in settings.conf)
The last of these "wins"; weights are constrained to 1..100
The weight isn't actually used in progress computation yet.
- For testing purposes, it's useful to load a module externally
and then register it to the ModuleManager (this hands off ownership).
- Refactor overall module loading to use the exposed single-module method.
- It is the requirements model (checking) that reports progress, and now
the model is accessible (ask for it with requirementsModel(), make the
messages come from there.
- The architecture of letting someone build up a list of requirements
from data emitted by the ModuleManager is broken: if it gets loaded
later, it will miss data; passing around complicated objects is
no fun anyway. Get rid of it, on the way to "ModuleManager has
its own model of requirements".
- Give the ModuleManager a RequirementsModel -- that is the source
of truth about the module-requirements of the modules managed
by that particular ModuleManager.
- Let the RequirementsChecker operate on a given RequirementsModel.
- the checker only collects and calls requirements; it has no
UI component, and only manages data (and a thread to do the
checking). Move it out of the UI library.
- this function lives in Module -- and is the only thing typing
Module to the ViewSteps and JobTypes. Split it out into its
own funciton. Nothing else in Module needs to befriend the
ViewSteps, so we move the friend declaration around a bit
as well.
- while here, apply coding style.
This is prep-work for moving module to libcalamares.
- Different libraries should have different EXPORTs, so that
you can IMPORT one while building the other. Reported (and
kindly explained) by Kevin Kofler.
- Stick to one header file, though.
While here, update copyright on file.
- The scattering of DLL export macro's is kind of useless;
there are several headers, and then the export macro isn't
even applied consistently. Just drop the one for UI exports,
which was only used in libcalamaresui.
This is an ugly hack, using Bill Auger's support for Job weights.
The unpackfs job is arbitrarily awarded a weight of 12. That makes it
(in a Netrunner install) use progress from 12% to 40% or so, overall,
as all the files are unpacked.
Also fixes bug reported by Kevin Kofler that unpackfs was only reporting
progress when it hit an exact multiple of 100 (instead of over 100).
SEE #1176
- this is currently just an alias for QVariantMap, which is
the type already in use.
- future plan is to tighten this up and have an actual
Descriptor class that carries only the information
actually needed for the module descriptor.
- Replace stringlist with a stronger-typed list of InstanceKey objects
- Move smashing-that-to-stringlist into consumers of the list
(just one, the debug window)
- introduce NamedEnum lookup tables for interface and type
- drop "final" and "virtual" from methods that don't make
sense as virtual
- shuffle declaration order so the virtual API for modules
sits together
