An app whose page has a beforeunload handler (CoinSpectrum) could not be
closed: tabs answer the page's "stay?" request, app windows had nothing
listening, and Electron reads silence as a veto. Closing the window is now
always the user's call; a reload or navigation inside the app asks, as a
tab does.
Removing it looked dead for a related reason. The confirmation was drawn
as Theseus's sheet in the main window, where the user was not looking (or
nowhere, with the main window closed), and the removal then closed the app
window with the same call the page vetoes. The question is now asked on
the app window that asked, and removal destroys the window.
Installed apps were only reachable from the address-bar chip while on the
site. Settings gets an Apps page, at theseus://settings/apps, that lists
them with Open and Remove and follows installs, removals and open windows.
The three list calls it uses are settings-only now.
A preload belongs to the WebContents, not the page: a website loaded into
the Settings tab kept window.cfg and could read every vault password, flip
settings and install extensions without consent. Settings and add-on tabs
now never load web content, and the channels behind settings-preload check
their sender. `navigate` no longer accepts calls from web pages.
Add-on updates trusted any publisherSig, whatever name it carried, even for
bundled add-ons. The trust root is now the installed addon.json (publisher,
or the operator key when there is none); versions must be plain dotted
numbers; a community install can't take over a bundled or foreign id.
Also:
- autofill matches and fills against the live URL, not a stale prov.host
- bns:// forwards the raw request path (..%2F escaped the name's bucket)
- clipboard-read denied, openExternal asks; forged collision choices ignored
- web pages can't window.open file:/chrome:/theseus:; data:/blob: no longer
go to the search engine; the quick-links panel loses home-preload
- clear-history-on-quit is awaited and removes history.json too
- update helper takes its paths from the environment (non-ASCII profiles)
- electrum poll has a deadline; misses wait at most 2.5 s
- p records go through Tor; add-on proxy credentials are actually used
- whole-folder require-cache bust on add-on version change; failed
activate() no longer leaks its request filter
- approvals released when the window closes; web-app ids stay on-origin
Install-this-app, remove-app, the extension install flow (install,
already installed, installed, not found, failed) and the add-on restart
question were still bare OS message boxes titled "theseus-navigator"
after page dialogs moved to the sheet. askSheet() is a drop-in for
dialog.showMessageBox with the same options and result: title as the
headline, detail under it, the caller's buttons with the default first,
an optional checkbox, and the app's or extension's icon when there is
one. Tone follows the box type (error, warning) or the wording. The
native box stays as the fallback when the browser window is not there,
and for the two synchronous cases (beforeunload, app windows).
0.3.56 was cut from the Aegis line (WizardConnect auto-detection, Aegis
0.8.x, PDF Editor and VPN updates) on top of 0.3.55; 0.3.57 carries that
plus the install-as-app feature and the two main-process crash fixes.
Electron ships Chromium's renderer without the browser-side web-app
install machinery, so beforeinstallprompt never fires and every site's
own "Install our app" chip (coin-spectrum.com's, for one) stays hidden
in Theseus. The browser side now exists:
- webapps.js reads a page's <link rel="manifest">, accepts it when it
names an app with a standalone-style display mode and a start_url on
the page's origin, and records the descriptor on the tab.
- The address bar shows an install chip for such pages (filled once the
app is installed: click then opens or removes it); the page context
menu carries the same entry.
- Pages get a synthetic beforeinstallprompt whose prompt() routes to the
Theseus install dialog and resolves userChoice like Chrome, and an
appinstalled event afterwards, so sites' own chips appear and work.
- Installing stores the app under <userData>/webapps/, wraps the
manifest icon into an .ico, writes a Start Menu (optionally desktop)
shortcut that launches Theseus with --app=<start_url>, and opens the
app in a chromeless window with its own taskbar identity. The window
shares the session, BCNR resolution, fingerprint and add-on bridges
with tabs; popups and "open in Theseus" go to the browser window,
Alt+arrows / F5 / Ctrl+R cover navigation without a toolbar.
- Theseus takes the single-instance lock so a shortcut launch lands in
the running browser (second-instance) instead of a second profile
owner; launched cold, --app= opens only the app window and a later
plain launch brings the browser window back.
