This temporary, upgrade-oriented logic depends on two assumptions:
- If the metadata-store is not running, we are still in the process of
applying the upgrade.
- If the above is true, all chats are /~host/name, all groups are
/~/~host/name, and they have a strict one-to-one relation.
Armed with those assumptions, we can deduce groups from chats and vice
versa without depending on the metadata-store, allowing us to carry on
as if it were already running.
If we %add-owned, then we add an entry to the access-control jug matching the
data we put into the synced map. When a permission gets deleted, we remove it
from synced, but previously neglected to clean up the matching access-control
entry.
This ensures that if a permission was deleted, and we had it registered as
owned, that the relevant access-control entry is removed from state.
We want to move from group/permission paths of the form /chat/~host/name
to /~/~host/name, merging the ./read and ./write permission paths into a
single permission matching the group path.
(The leading /~ signifies an "unmanaged" group, one used by apps
internally, and not explicitly exposed to the user as a contacts group.)
This upgrade logic does roughly the following, for every chat path, to
accomplish the migration:
1. delete ./read and ./write groups associated with the chat
2. create a new group containing an approximate "uni" of the old groups
3. register the chat + new group with the metadata-store
4. hook the group up to its matching permission set
Note that because existing groups are hooked up through the
permission-group-hook, doing step 1 deletes the associated permissions.
Step 4 then re-establishes that relation for the newly created group.
The logic here scries into the metadata-store, and as such depends on
that having been started prior to this upgrade process.
When permissions change, find out which chats are impacted (on the
assumption that permission paths are group paths), then perform actions
wrt that chat accordingly.
When a chat is interacted with, find out which groups the chat is
associated with, then use those to perform permission checks. If the
check passes for any group, permission is granted.
We may %hear or %read content that was posted some time ago, so we need
to make sure we add it at the appropriate position (wrt timestamp)
rather than just sticking it at the head of the list.
Shortcuts the existing retry timer by having new members send out a poke
when they acknowledge joining the group.
The existing retry logic is left in place to deal with other cases of
subscription failure.
Also fixes an incorrect relevancy check during subscription retries, now
properly preventing duplicate subscriptions.
We were scrying for /gx/path instead of /gx/=link-store=/path.
In the %annotations case, that path wasn't even correct.
Also refactors scries out into a +scry-for helper.
This lines up the input with the "Set location" button,
and makes the latitude/longitude setting error
more concise, in order to fit within the tile without overflow.
This commit also removes some Tachyons-specific CSS classes.
Specifically, this commit removes the add action from the contact-view
and replaces it with a listener within contact-hook for additions
to groups. This means that when a ship is added to a group that the
contact-hook is watching, the ship is automatically sent an invite to
join that "managed group" from the contacts application. This also
includes the UI integration work on the management screen and settings
screen for working with the new group / permission structure.
On the frontend, updates the route path to include the (base64-encoded)
url. Uses that and the load-single functionality to support loading
directly into a submission page, which fetches just the requested
submission.
Also ensures we don't open duplicate comment subscriptions.
