2024-08-31 Un point sur l'état d'avancement du client:
TODO (bottlenecks)
- images (++)
- arbres (et listes) (++)
- logging (ref : /var/log/messages)
- menus (pas indispensables à ce stade)
À redéfinir: répartition des tâches (mesures) client/serveur.
Comment traiter le cas extrême où *toutes* les règles
sont des règles d'intérêt ?
(cas d'une erreur rare, non systématique où il faut "remonter le temps",
pas à pas, à partir du premier état qui met l'erreur en évidence)
Pour effectuer cette "remontée", il faut une liste complète
de toutes les règles appliquées.
Cette liste doit comporter, pour chaque item (= chaque exécution d'une règle):
- identité de la règle
- lieu d'exécution (dans l'espace global)
- date d'exécution
NB Il ne peut y avoir d'ambiguité ou d'erreur due au parallélisme
car, si les espaces locaux de deux exécutions de règles se recouvrent,
elles ne peuvent avoir été exécutées simultanément.
À mon avis, le serveur ne peut effectuer cette tâche car
la "remontée dans le temps" nécessite l'inspection 'de visu' de chaque état.
Inspection veut dire ici: reconnaissance de formes
et ce travail (visuel) ne peut être pré-programmé
(bien qu'il doive être systématique), car le concepteur du modèle
ne sait pas quelle est l'erreur et ne peut prévoir ce qu'il va découvrir.
Ceci n'exclut pas qu'il puisse - qu'il doive - effectuer plusieurs essais
(de "remontée dans le temps") en sélectionnant, par exemple,
différentes règles d'intérêt à chaque fois
ni qu'il puisse se programmer des outils d'aide
(mais tout ceci ne semble pas avoir sa place dans le serveur).
NB À ce stade de la conception d'un modèle, les erreurs sont encore fréquentes
et les 'runs' sont nécessairement de brève durée.
Des 'runs' de longue durée n'ont de sens qu'une fois ce débuggage effectué.
Il y a donc peu de problèmes à craindre du fait de la limite de la bande passante.

A GtkListItemFactory creates widgets for the items taken from a GListModel.
https://docs.gtk.org/gtk4/class.ListItemFactory.html
GtkBuilderListItemFactory is a GtkListItemFactory that creates widgets by instantiating GtkBuilder UI templates.
The templates must be extending GtkListItem, and typically use GtkExpressions to obtain data from the items in the model.
https://docs.gtk.org/gtk4/class.BuilderListItemFactory.html
GListModel is an interface that represents a mutable list of GObjects. Its main intention is as a model for various widgets in user interfaces, such as list views, but it can also be used as a convenient method of returning lists of data, with support for updates.
