Summary:
Ref T4103. This removes these options:
{F1660585}
The jump nav option came from T916, when we had a separate jump nav on the home page. Essentially no one has ever been confused by the behavior of search or disabled this feature. Here are the stats for this install:
| Total Users | 36656 |
| Have Set Any Preference | 3084 |
| Have Disabled Jump | 6
| Are Not "Security Researchers" | 2
| Any Account Activity | 0
The "/" option came in the same change, but the preference came from T989. This keystroke conflicts with a default Firefox keystroke. Almost no one cares about this either, but I count 6 real users who have disabled the behavior. I suspect the number of real users who //use// it may be smaller.
In Safari and Firefox, the "tab" key does the same thing.
In Chrome, the "tab" key does the same thing if {nav Preferences > Web Content > "Pressing Tab highlights..."} is disabled.
Upshot: jump nav is great, bulk of the change in T989 was clearly great, specific preferences that came out of it seem not-so-great and now is a good time to kill them as we head into T4103.
Test Plan:
- Grepped for removed constants.
- Pressed "/".
- Searched for `T123`.

Summary:
Ref T10917. Currently, when you delete an SSH key, we really truly delete it forever.
This isn't very consistent with other applications, but we built this stuff a long time ago before we were as rigorous about retaining data and making it auditable.
In partiular, destroying data isn't good for auditing after security issues, since it means we can't show you logs of any changes an attacker might have made to your keys.
To prepare to improve this, stop destoying data. This will allow later changes to become transaction-oriented and show normal transaction logs.
The tricky part here is that we have a `UNIQUE KEY` on the public key part of the key.
Instead, I changed this to `UNIQUE (key, isActive)`, where `isActive` is a nullable boolean column. This works because MySQL does not enforce "unique" if part of the key is `NULL`.
So you can't have two rows with `("A", 1)`, but you can have as many rows as you want with `("A", null)`. This lets us keep the "each key may only be active for one user/object" rule without requiring us to delete any data.
Test Plan:
- Ran schema changes.
- Viewed public keys.
- Tried to add a duplicate key, got rejected (already associated with another object).
- Deleted SSH key.
- Verified that the key was no longer actually deleted from the database, just marked inactive (in future changes, I'll update the UI to be more clear about this).
- Uploaded a new copy of the same public key, worked fine (no duplicate key rejection).
- Tried to upload yet another copy, got rejected.
- Generated a new keypair.
- Tried to upload a duplicate to an Almanac device, got rejected.
- Generated a new pair for a device.
- Trusted a device key.

Summary:
Ref T10860. This allows us to recover if the connection to the database is lost during a push.
If we lose the connection to the master database during a push, we would previously freeze the repository. This is very safe, but not very operator-friendly since you have to go manually unfreeze it.
We don't need to be quite this aggressive about freezing things. The repository state is still consistent after we've "upgraded" the lock by setting `isWriting = 1`, so we're actually fine even if we lost the global lock.
Instead of just freezing the repository immediately, sit there in a loop waiting for the master to come back up for a few minutes. If it recovers, we can release the lock and everything will be OK again.
Basically, the changes are:
- If we can't release the lock at first, sit in a loop trying really hard to release it for a while.
- Add a unique lock identifier so we can be certain we're only releasing //our// lock no matter what else is going on.
- Do the version reads on the same connection holding the lock, so we can be sure we haven't lost the lock before we do that read.
Test Plan:
- Added a `sleep(10)` after accepting the write but before releasing the lock so I could run `mysqld stop` and force this issue to occur.

When we read (e.g., `git fetch`) the logic goes like this:
- Get the read lock (unique to device + repository).
- Read all the versions of the repository on every other device.
- If any node has a newer version:
- Fetch the newer version.
- Increment our version to be the same as the version we fetched.
- Release the read lock.
- Actually do the fetch.
This makes sure that any time you do a read, you always read the most recently acknowledged write. You may have to wait for an internal fetch to happen (this isn't actually implemented yet) but the operation will always work like you expect it to.
When we write (e.g., `git push`) the logic goes like this:
- Get the write lock (unique to the repository).
- Do all the read steps so we're up to date.
- Mark a write pending.
- Do the actual write.
- Bump our version and mark our write finished.
- Release the write lock.
This allows you to write to any replica. Again, you might have to wait for a fetch first, but everything will work like you expect.
There's one notable failure mode here: if the network connection between the repository node and the database fails during the write, the write lock might be released even though a write is ongoing.
The "isWriting" column protects against that, by staying locked if we lose our connection to the database. This will currently "freeze" the repository (prevent any new writes) until an administrator can sort things out, since it'd dangerous to continue doing writes (we may lose data).
(Since we won't actually acknowledge the write, I think, we could probably smooth this out a bit and make it self-healing //most// of the time: basically, have the broken node rewind itself by updating from another good node. But that's a little more complex.)
Test Plan:
- Pushed changes to a cluster-mode repository.
- Viewed web interface, saw "writing" flag and version changes.
- Pulled changes.
- Faked various failures, got sensible states.

Summary:
Ref T4571. Allows users to click the "read-only mode" notification to get more information about why an install is in read-only mode.
Installs can be in this mode for several reasons (explicit administrative action, no masters defined, no masters reachable), and it's useful to be able to tell the difference.

Summary:
Ref T4571. This adds a new option which allows you to upgrade your one-host configuration to a multi-host configuration by configuring it.
Doing this currently does nothing. I wrote a lot of words about what it is //supposed// to do in the future, though.
Test Plan:
- Tried to configure the option in all the possible bad ways, got errors.
- Read documentation.
