feat(v3/linux): allow overriding the GTK application id#5972overlordtm wants to merge 12 commits into
Conversation
appNew hardcoded the id as "org.wails." plus a sanitised Options.Name. WebKit derives the accessibility bus name it asks the portal to own from that id, and a flatpak may only own names prefixed with its own app id, so the request is refused and the web process aborts. The abort reaches Go as a SIGTRAP raised during the cgo call to g_application_run, which reads as a Wails or GTK crash rather than a permission refusal. Add Options.Linux.ApplicationID, defaulting to the derived id when unset, so an app can match the id its packaging requires.
The Linux options block listed fields with no explanation. Describe the three, and call out that sandboxed builds have to set the application id, since the symptom otherwise reads as a crash in Wails or GTK rather than a permission refusal.
Assert that ApplicationID is used verbatim when set and that an application which leaves it unset keeps the id it had before the option existed, since that fallback is what makes the option backward compatible. The test file is tagged for linux && cgo without excluding gtk3, so it runs against both backends, which derive the id identically.

GTK3 still has a failure path through ProgramName, gtk3 gives wayland its appid via |
GTK only asserts on the application id, so a value that g_application_id_is_valid() rejects made gtk_application_new() return NULL and took the process down during startup, far away from the option that caused it. Check the id against the same contract up front, report it through the error handler and start with the derived org.wails.<name>. Both backends carried identical copies of sanitizeAppName and applicationID, so the id logic moves to application_linux_appid.go and is shared by the GTK3 and GTK4 builds rather than duplicating the validator as well. Deriving an id could not satisfy that contract either: sanitizeAppName prefixed a leading digit with an underscore and then trimmed it right back off, so Name "1Password" produced org.wails.1password, whose last element starts with a digit. Prefix after the trim, and clamp the derived id to the 255 character limit.
GTK takes the Wayland surface app_id from g_get_prgname(), not from the application id, so setting only ApplicationID left windows matching the executable name instead of the .desktop file. ProgramName now inherits the resolved application id. Setting it explicitly still wins, and applications that set neither option keep the executable name.

Functionality looks good, Thank you @overlordtm for addressing those changes. @leaanthony talisin seemed to clobber a bunch of extra stuff in Implementation.md, which should likely be removed in general from the project? outside scope of this PR though. It also added Changelog changes? which I thought we get rid of? we likely should assess the value its adding in general but certainly update some prompting. It changed no functionality from OP's original efforts and just kinda added a bunch of useless stuff and made merge conflicts. IMO it should not be just taking on PR's adding whatever and then getting merged/committed without any approvals. Thanks again Andraz |

My bad! Bot was far too eager. There was a triage cron job which originally was focused on issues but didn't take into account existing PRs. Apologies @overlordtm and @atterpac - I'll tidy up 🙏 |
Merge current master, preserve the contributor's ApplicationID implementation, and remove the automation-added implementation tracker expansion and manual unreleased changelog entries.

Description
A Wails v3 app packaged as a flatpak is killed on startup by its own WebKit web
process, and no application option can prevent it:
A flatpak may only own bus names prefixed with its own app id. WebKit derives the
accessibility bus name it asks the portal to own from the GtkApplication id, and
appNewhardcoded that id:org.wails.*can never match the app id of any flatpak, whatever the manifestsays, and nothing in
application.Optionscould change it. Every Wails v3 apppackaged as a flatpak with a webview hits this. The abort reaches Go as a
SIGTRAPraised during the cgo call tog_application_run, which reads as aWails or GTK crash rather than a permission refusal.
This adds
Options.Linux.ApplicationID, which overrides the id and defaults tothe existing derived value when unset. Both backends route through a new
applicationID(options)helper, andappNewnow takes the finished id insteadof assembling it.
Setting it to the packaging's app id also lets the desktop match windows to the
installed
.desktopentry, which the derived id never does.v3/examples/linux-flatpak-appid(deleted in last commit for cleanup reasons) demonstrates it, with a manifest whose app id differs from the derived id.Opt-in and backward compatible: an app that does not set
ApplicationIDgetsexactly the id it gets today.
