Backporting

Timeline

  • Immediate: patchset needed as soon as possible
  • Next Minor Stable Release: patchset that needs to be verified in nightly before backport
  • Eventually: patchset that needs to be verified in alpha before backport
  • No Backport (preferred): patchset for the next major stable

(Optional) Justification

  • Emergency security update: patchset fixes CVEs, 0-days, etc
  • Censorship event: patchset enables censorship circumvention
  • Critical bug-fix: patchset fixes a bug in core-functionality
  • Consistency: patchset which would make development easier if it were in both the alpha and release branches; developer tools, build system changes, etc
  • Sponsor required: patchset required for sponsor
  • Localization: typos and other localization changes that should be also in the release branch
  • Other: please explain

Merging

  • Merge to tor-browser - !fixups to tor-browser-specific commits, new features, security backports
  • Merge to base-browser - !fixups to base-browser-specific commits, new features to be shared with mullvad-browser, and security backports
    • NOTE: if your changeset includes patches to both base-browser and tor-browser please clearly label in the change description which commits should be cherry-picked to base-browser after merging

Change Description

With this patch we send some TorConnect events to Android.

We might need to tweak them a little bit to include additional information (like we do in TorConnectParent), but so far they're what TorConnect emits.

This would be important to restore the tab bar after the bootstrap ends.

Also, added a temporary message to open settings from the HTML page, otherwise users risk to be trapped in it.

How Tested

I've added an observer to the events in TorController.kt (because I knew it was a place where I could add stuff that is launched early).

However, something similar should be added to the UI section, or somewhere else at least to open the settings.

I bootstrapped and checked that I got notifications in logcat.

Also, I checked that I got a log entry for clicking in the open settings button.

Finally, checked that "Configure Connection" still works on desktop 😂.
