This affects FKs pointing to both Contact and ContactHistory. This is in
preparation to us deleting all rows in those two tables, and then subsequently
removing all application logic having to do with contacts entirely.
I analyzed SQL statements run during the following flows and EXPLAIN
ANALYZEd each of them to figure out if there are any additional hash
indexes we could add that could be particularly helpful. Note: it's not
worth adding a hash index on the host_repo_id field in DomainHost
because so many rows (domains) use the same host.
- domain create
- domain delete
- domain info
- domain renew
- domain update
- host create
- host delete
- host update
I skipped the ones that use the read-only replica, as well as contact
flows (we're getting rid of them), and domain transfer/restore-related
flows as those are extremely infrequent.
I went through all the SQL statements generated by some sample
DomainCreateFlow and DomainDeleteFlow cases to find situations where we
were either SELECTing from, or UPDATEing, tables with a direct "field =
value" format. These are the situations that I found where we can add
hash indexes. This does two things:
1. Makes these queries slight faster, since these are usually queries on
columns that are either unique or very close to unique, and O(1) is
faster than O(log(n))
2. Spreads around the optimistic predicate locks on the previously-used
btree indexes. Many of our serialization errors came from the fact
that we were autogenerating incrementing ID values for various
tables, meaning that SELECTs, INSERTs, and UPDATEs would all try to
take predicate locks out on the same page of the btree index. Using a
hash index means that the page locks will be spread out to various
index pages, rather than conflicting with each other.
Running load tests on alpha I see significant improvements in speed and
error rates. Speed is hard to quantify due to the nature of the way the
load tests distribute tasks among the queues but it could be more than
50% improvement, and serialization errors in the logs drop by more than
90%.
We've moved these over to the User class, so we should remove these for
clarity. In addition, we should make it clear (in Java at least) that
the field in the RegistryLock object refers to the email address used
for the lock in question.
This is the first in a series of PRs to implement the expiry access period
(XAP). The overall fee schedules will be set in YAML config files, so the only
DB change necessary should be this single new boolean column on the Tld entity,
which defaults to false so as to require XAP explicitly being turned on for a
given TLD.
BUG=http://b/437398822
Postgresql-17.6 introduces two new lines in pg_dump output as a
security feature: `\restricted {HASH}` and `\unrestricted {HASH}`.
We filter out lines starting with these two prefixes when comparing
schemas.
The db upgrade also adds two empty lines to the pg_dump output. We
know ignore all empty lines when comparing schemas.
A future PR will add the actions that save and use this object. That
future PR will also require loading RegistrarPoc objects given the
registrar ID, hence the change in that class.
1. This doesn't remove the SQL tables yet (this is necessary to pass
tests and also good practice just in case we need or want to look at
history for a little bit)
2. This also removes the Registrar, RegistrarPoc, and User base classes
that were only necessary because we were saving copies of those
objects in the old history classes.
This changes the code to only save console histories of this type. We
keep the old Java code (and, necessarily, the corresponding SQL code)
for now because there's no harm in doing so and we want to avoid hastily
deleting too much.
We now pin to postgreSQL v17 when running tests, which means that minor
version might increase without our intervention. This causes (at least)
the comment in the golden schema to change, and failing the test as a
result.
This PR adds the ability to strip lines that we deem as comment from the
comparison, so we don't have to do trivial upgrades to the gold schema
whenever there's minor version upgrade.
I obtained access to an IBM s390x VM so I thought I'd see how multi-arch
Nomulus is.
Our main application is in Java so it is already multi-arch, but several
tests use docker images that are by default x64. Luckily postgres has an
s390x port, but selenium does not. So I had to disable Screenshot tests
when the arch is not amd64.
- We never delete rows from DomainHistory (and even if we do in the
future, they'll be old / the references won't matter)
- This is likely creating lock contention when lots of requests come
through at once for domains with many DomainHistory entries
There are some breaking method changes in the 10.x.y versions and we're encountering exceptions when trying to run the flywayMigrate task thanks to those.
We only include the deletion time if the domain is in the 5-day
PENDING_DELETE period after the 30 day REDEMPTION period. For all other
domains, we just have an empty string as that field.
This is behind a feature flag so that we can control when it is enabled
* Include discount price in domai n pricing
* Partial progress in logic
* Tests and logic passing
* Change pricing for multi year create
* Tests for discount pricing logic
* Token currency check
* Add some comments
* Java formatting
* Discount price to Optional
* Change discount price to be optional nullable
* Re-add deleted tests
This is the first step in the field removal (second will be removing the
column from SQL once this is deployed).
There's no point in using a UserDao versus just doing the standard
loading-from-DB that we do everywhere else. No need to special-case it.
