Attempting to run DeleteOldCommitLogs in prod resulted in a lot of DatastoreTimeoutException errors. The assumption is that attempting to load so many CommitLogManifests (over 200 million of them), when each one has a slight possibility of failure, has a very high probability of error.
The shard aborts after 20 of these errors, and by eliminating as many loads as possible and retrying the remaining loads inside a transaction we are effectively eliminating any exceptions "leaking" out to the mapreduce framework, which will hopefully keep us bellow 20. At least, that's our best guess currently as to why the mapreduce fails.
EppResources are loaded in the map stage to get the revisions, and CommitLogManifests are only loaded in the reduce stage for sanity check so we don't accidentally delete resources we need in prod. Both of these are wrapped in transactNew to make sure they retry individually.
The only "load" not done inside a transaction is the EppResourceIndex, but there's no getting around that without rewriting the EppResourceInputs.

The auth logging has been useful, but it now generates a sizeable percentage of all logging, because it spits out three to five lines for every request in the system. This CL reduces that to two to three. We may eventually want to reduce it further, but this is a good start.

When the registrar console code determines that a user has not logged in, it redirects to a login page. But when authenticating as an internal request (which should never happen), the redirection code encountered an exception, resulting in a 500 error.

A NullPointerException reported via StackDriver appears to stem from trying to load the claims list right at the moment it was being updated. Since the update only happens once every 12 hours, retrying the load once should fix the problem, if this is really the cause.

It was buggy (didn't work) and was never actually used.
Why never actually used: for it to be used executeWithLock has to be called
with different requesters on the same lockId. That never happend in the code.
How it was buggy: Logically, the queue is deleted on release of the lock (meaning it was
meaningless the only time it mattered - when the lock isn't taken). In
addition, a different bug meant that having items in the queue prevented the
lock from being released forcing all other tasks to have to wait for lock
timeout even if the task that acquired the lock is long done.
Alternative: fix the queue. This would mean we don't want to delete the lock on release (since we want to keep the queue). Instead, we resave the same lock with expiration date being START_OF_TIME. In addition - we need to fix the .equals used to determine if the lock the same as the acquired lock - instead use some isSame function that ignores the queue.
Note: the queue is dangerous! An item (calling class / action) in the first place of a queue means no other calling class can get that lock. Everything is waiting for the first calling class to be re-run - but that might take a long time (depending on that action's rerun policy) and even might never happen (if for some reason that action decided it was no longer needed without acquiring the lock) - causing all other actions to stall forever!

This will make DNS issues easier to debug retroactively as we will be
able to determine, by looking at the logs, if the queue size was growing
unbounded.
Also adds some logging helpers to allow programmatically choosing the level
of logging.

This makes the code more understandable from callsites, and also forces
users of this function to deal with the situation where the registrar
with a given client ID might not be present (it was previously silently
NPEing from some of the callsites).
This also adds a test helper method loadRegistrar(clientId) that retains
the old functionality for terseness in tests. It also fixes some instances
of using the load method with the wrong cachedness -- some uses in high-
traffic situations (WHOIS) that should have caching, but also low-traffic
reporting that don't benefit from caching so might as well always be
current.

Note that even though the nomulus command line tool now supports multiple
DNS writers for all subcommands, this still won't work quite yet because
the DNS task queue format migration from [] is still in progress.
After next week's push that migration will be complete and we can remove
the final restriction against only having one DNS writer per TLD.

that are too young, but this adds an explicit sanity check for safety's

This change is motivated by the sandbox run where we saw the backend instances overwhelmed by the 100 default shards to the point where they couldn't even answer a simple status request.
Production has 50 backend instances, so 20 will leave a lot of spare for other tasks.

This is written in such a way that it can safely handle task items in the
old format so long as the DNS writer to use for the given TLD is unambiguous
(which it is for now, until we allow multiple DNS writers to be configured).

We want to be safer and more explicit about the authentication needed by the many actions that exist.
As such, we make the 'auth' parameter required in @Action (so it's always clear who can run a specific action) and we replace the @Auth with an enum so that only pre-approved configurations that are aptly named and documented can be used.

This is the first step in a multi-step data migration to allow multiple
DNS writers per TLD. The overall process looks like this:
1. Add a plural DNS writers field with backfill (this commit).
2. Deploy it.
3. Run the ResaveEnvironmentEntitiesCommand to populate this new field
on all entities.
4. Update the code to use the new field everywhere.
5. Deploy it.
6. Delete the now-unreferenced, old deprecated singular value field.
This process is rollback-safe.

We're already storing this as a metric, but on a registry of our
scale these operations tend to only happen on a daily-ish basis,
for which seeing results in logs is easier to deal with than metrics
(and also still very light-weight).

into App Engine, as an official part of the Nomulus package. This copies the
structure of RDE uploads, with a few changes specific to monthly reporting.
I've left some TODOs related to actually testing it on the ICANN endpoint, as we're still not sure how files to be uploaded will be staged, and whether we can actually ping their endpoint on valid ports (80 or 443).

This will allow us to migrate one TLD at a time by refreshing all zones
on the specified TLD after dual-writing is enabled.
Note that the TLDs parameter is required, which seems reasonable given
that almost all imagined use cases would be on a by-TLD basis.

Up to now, our search wildcard rules have been that there must be an initial string of at least two characters. If a wildcard is present after that, it can optionally be followed by a suffix specifying the TLD (for domains) or domain (for nameservers). So domain queries can look like:
example.tld
ex*
ex*.tld
and nameserver queries can look like:
ns1.example.tld
ns*.example.tld
ns*
But you can't do a domain query for *.tld, nor a nameserver query for *.example.tld. It would be nice to support such queries, and the presence of a valid TLD or domain makes them relatively efficient. This CL relaxes the restrictions to allow wildcards with no initial string if the suffix is present. For nameservers, the suffix must be a valid domain in the system, to avoid having to loop through all nameservers.
A side effect of the changes is to fix a shortcoming in the logic which caused wildcard nameserver searches to fail if the specified domain suffix referred to an external domain.
Entity searches are not affected, since they do not support suffixes.
