Ref T9028. This allows us to detect when commits are unreachable:
- When a ref (tag, branch, etc) is moved or deleted, store the old thing it pointed at in a list.
- After discovery, go through the list and check if all the stuff on it is still reachable.
- If something isn't, try to follow its ancestors back until we find something that is reachable.
- Then, mark everything we found as unreachable.
- Finally, rebuild the repository summary table to correct the commit count.
Test Plan:
- Deleted a ref, ran `pull` + `refs`, saw oldref in database.
- Ran `discover`, saw it process the oldref, mark the unreachable commit, and update the summary table.
- Visited commit page, saw it properly marked.

Ref T9028. This improves the daemon behavior for unreachable commits. There is still no way for commits to become marked unreachable on their own.
- When a daemon encounters an unreachable commit, fail permanently.
- When we revive a commit, queue new daemons to process it (since some of the daemons might have failed permanently the first time around).
- Before doing a step on a commit, check if the step has already been done and skip it if it has. This can't happen normally, but will soon be possible if a commit is repeatedly deleted and revived very quickly.
- Steps queued with `bin/repository reparse ...` still execute normally.

- Used `bin/repository reparse` to run every step, verified they all mark the commit with the proper flag.

Ref T9028. Fixes T6878. Currently, we only fetch and discover branches. This is fine 99% of the time but sometimes commits are pushed to just a tag, e.g.:
```
git checkout <some hash>
nano file.c
git commit -am '...'
git tag wild-wild-west
git push origin wild-wild-west
```
Through a similar process, commits can also be pushed to some arbitrary named ref (we do this for staging areas).
With the current rules, we don't fetch tag refs and won't discover these commits.
Change the rules so:
- we fetch all refs; and
- we discover ancestors of all refs.
Autoclose rules for tags and arbitrary refs are just hard-coded for now. We might make these more flexible in the future, or we might do forks instead, or maybe we'll have to do both.
Test Plan:
Pushed a commit to a tag ONLY (`vegetable1`).

Summary:
Ref T4292. For hosted, clustered repositories we have a good way to increment the internal version of the repository: every time a user pushes something, we increment the version by 1.
We don't have a great way to do this for observed/remote repositories because when we `git fetch` we might get nothing, or we might get some changes, and we can't easily tell //what// changes we got.
For example, if we see that another node is at "version 97", and we do a fetch and see some changes, we don't know if we're in sync with them (i.e., also at "version 97") or ahead of them (at "version 98").
This implements a simple way to version an observed repository:
- Take the head of every branch/tag.
- Look them up.
- Pick the biggest internal ID number.
This will work //except// when branches are deleted, which could cause the version to go backward if the "biggest commit" is the one that was deleted. This should be OK, since it's rare and the effects are minor and the repository will "self-heal" on the next actual push.
Test Plan:
- Created an observed repository.
- Ran `bin/repository update` and observed a sensible version number appear in the version table.
- Pushed to the remote, did another update, saw a sensible update.
- Did an update with no push, saw no effect on version number.
- Toggled repository to hosted, saw the version reset.

Summary:
Ref T4292. Currently, we hold one big lock around the whole `bin/repository update` workflow.
When running multiple daemons on different hosts, this lock can end up being contentious. In particular, we'll hold it during `git fetch` on every host globally, even though it's only useful to hold it locally per-device (that is, it's fine/good/expected if `repo001` and `repo002` happen to be fetching from a repository they are observing at the same time).
Instead, split it into two locks:
- One lock is scoped to the current device, and held during pull (usually `git fetch`). This just keeps multiple daemons accidentally running on the same host from making a mess when trying to initialize or update a working copy.
- One lock is scoped globally, and held during discovery. This makes sure daemons on different hosts don't step on each other when updating the database.
If we fail to acquire either lock, assume some other process is legitimately doing the work and bail more quietly instead of fataling. In approximately 100% of cases where users have hit this lock contention, that was the case: some other daemon was running somewhere doing the work and the error didn't actually represent an issue.
If there's an actual problem, we still raise a diagnostically useful message if you run `bin/repository update` manually, so there are still tools to figure out that something is hung or whatever.
Test Plan:
- Ran `bin/repository update`, `pull`, `discover`.
- Added `sleep(5)`, forced processes to contend, got lock exceptions and graceful exit with diagnostic message.

Summary:
Fixes T10940. Two issues currently:
First, `PullLocal` deamon refuses to update non-cluster repositories on cluster devices. However, this is surprising/confusing/bad because as soon as you enroll a repository host in the cluster, most of the repositories on it stop working until you `clusterize` them. This is especially confusing because the documentation gives you a very nice, gradual walkthrough about going through things slowly and being able to check your work at every step, but we really drop you off a bit of a cliff here. The workflow implied by the documentation is a desirable one.
This operation is generally only unsafe/problematic if the daemon would be creating a //new// working copy. If a working copy already exists, we can reasonably guess that it's almost certainly because you've enrolled a previously un-clustered host into a new cluster. This allows the nice, gradual workflow the documentation describes to proceed as expected, without any weird surprises.
Instead of refusing to update these repositories, only refuse to update them if updating would create a new working copy. This should make transitioning much smoother without any meaningful reduction in safety.
Second, the lower-level `bin/repository update`, `refs`, `mirror`, etc., commands don't apply this same check. However, these commands are potentially just as dangerous. Use the same code to do a similar check there, making sure we only operate on repositories that are either expected to be on the current device, or which already exist here.
Test Plan:
- Ran `bin/phd debug pull`, saw diagnostic information choose to update most repositories (including some non-cluster repositories) but properly skip non-cluster repositories that do not exist locally.
- Ran `bin/repository update`, etc., saw the command apply consistent rules to the rules applied by `PullLocal` and refuse to update non-local repositories it would need to create.

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.
- Pushed like this:
```
$ echo D >> record && git commit -am D && git push

Summary:
Ref T4292. Sometimes, we may not have a working copy for a repository. The easiest way to get into this condition is to deactivate a repository.
We could try to clone + fetch in this case, but that's kind of complex, and there's an easy command that administrators can run manually. For now, just tell them to do that.
This affects the inactive repositories on `secure`, like rGITCOINS.
Test Plan: Removed working copy, got message.

Summary:
Ref T4292. When the daemons make a query for repository information, we need to make sure the working copy on disk is up to date before we serve the response, since we might not have the inforamtion we need to respond otherwise.
We do this automatically for almost all Diffusion methods, but this particular method is a little unusual and does not get this check for free. Add this check.
Test Plan:
- Made this code throw.
- Ran `bin/repository reparse --message ...`, saw the code get hit.
- Ran `bin/repository lookup-user ...`, saw this code get hit.
- Made this code not throw.

Summary:
Ref T4292. Right now, repository versions only get marked when a write happens.
This potentially creates a problem: if I pushed all the sync code to `secure` and enabled `secure002` as a repository host, the daemons would create empty copies of all the repositories on that host.
Usually, this would be fine. Most repositories have already received a write on `secure001`, so that working copy has a verison and is a leader.
However, when a write happened to a rarely-used repository (say, rKEYSTORE) that hadn't received any write recently, it might be sent to `secure002` randomly. Now, we'd try to figure out if `secure002` has the most up-to-date copy of the repository or not.
We wouldn't be able to, since we don't have any information about which node has the data on it, since we never got a write before. The old code could guess wrong and decide that `secure002` is a leader, then accept the write. Since this would bump the version on `secure002`, that would //make// it an authoritative leader, and `secure001` would synchronize from it passively (or on the next read or write), which would potentially destroy data.
Instead:
- Refuse to continue in situations like this.
- When a repository is on exactly one device, mark it as a leader with version "0".
- When a repository is created into a cluster service, mark its version as "0" on all devices (they're all leaders, since the repository is empty).
This should mean that we won't lose data no matter how much weird stuff we run into.
Test Plan:
- In single-node mode, used `repository update` to verify that `0` was written properly.
- With multiple nodes, used `repository update` to verify that we refuse to continue.
- Created a new repository, verified versions were initialized correctly.
